just myself

Recently, the United States, University of Illinois at Urbana - Champaign (University of Illinois at Urbana-Champaign) of the John Rogers (John Rogers), led by scientists discovered a new high-efficiency silicon solar cell production. This means the production of silicon solar cells is the flexibility and scalability to roll in pencil, a transparent and even as the building and automotive glass windows of colorants laptop battery  .

Published in the online journal “Nature - Materials” (Nature Materials) on a report that a new type of method can be used to the traditional silicon processing, is about to cut crispbread fragile silicon micro-thin ultra-fine Silicon, and then carefully transfer them to another extension of the flexible material on the surface.

The new leader of the research Rogers said: “We can make super-thin silicon can be attached to the plastic on any curl. Can also make silicon thin film or a film-like, glass, construction incorporation. This Building for the use of solar battery energy has become a platform opens up space. ”

As the global oil prices, coupled with people’s concerns about global warming, greatly increased the demand for solar cells.

Many of the world, such as Japan consumer electronics maker Sharp Corporation (Sharp Corp) and the German photovoltaic cell giant Q’s (Q-Cells) have a thin film solar cell production, however, this type of thin film solar cells in solar energy will be converted to electrical energy On the general efficiency of less than traditional solar cells.

Rogers said the technology used in the traditional silicon, they are “rugged, high efficiency, however, now appears to be too rigid and therefore fragile.” Rogers they adopted a method of etching silicon to deal with these Hp battery   . In a large silicon surface Guaxia small debris, the debris than the thin silicon wafers would also like to book 10 times to 100 times, and because of the small size, more user-friendly.

Guaxia silicon debris, the equivalent of a “rubber stamp” of these devices Zhanqu debris, and then they will be “printed” into other substances on the surface.

Rogers said: “These Guaxia Lai silicon debris as ink. Guaxia debris after the big silicon thin silicon surface has become the ’stamp pad’. Just ’seal’ to ’stamp pad’ in the silicon debris’ India ‘to other objects to the surface. ”

He said that as long as the final step in the electronic equipment used in solar cells will power Export it  HSTNN-LB31 .

Silicon material to increase the flexibility of making silicon solar cells more lightweight, easy to carry. Rogers looking forward to the future of silicon solar cells “can be rolled up like a carpet into the same truck.”

He said that the newly established North Carolina’s Durham County Semprius is the registration of the technical consultation.

Rogers said: “We only change the way we have the advantage of familiar things.”

In April 2008, Xiasha in Hangzhou Economic and Technological Development Zone, a petty building, Long Yan Energy Science and Technology (Hangzhou) Co., Ltd. was established. The total investment of 24,000,000 U.S. dollars of the company to do things very advanced: CdTe thin film batteries and components can be. Although their product is still in the stage of research and development laboratory, to be formally put into operation in 2009, they set up in the company to get on the first day of the domestic venture capital investment  ThinkPad R50 battery   in Lenovo’s big money, and Legend Capital Partners for the “Success” is very happy to invest.

In the use of lithium batteries should be noted that for a period of time after the battery is placed into hibernation, lower than normal capacity at this time, the time has also come to shorten. However, lithium batteries can easily activated, as long as after 3-5 times the normal charge-discharge cycle of the laptop battery can be activated, the resumption of normal capacity.
As the battery lithium own characteristics, its decision is almost no memory effect. Therefore, cell phone users in a new lithium battery in the activation process does not require special methods and equipment. Not only is the theory that, from my own practice, from the very beginning, the use of standard methods of charging that “activation” is the best way.
Lithium batteries for the “activation”, a large number of claims: the time to charge more than 12 hours, repeated three times to do in order to activate the battery. “The first three necessary and sufficient to charge more than 12 hours”, it is obvious from the nickel battery (such as nickel-cadmium and nickel metal hydride) inherited. This is why it can be said is the beginning of miscommunication. Lithium batteries and nickel battery charge and discharge characteristics of a very big difference, but also very clear to tell you that I have had access to all the serious official stressed that all technical information and charge-off will discharge lithium batteries, especially lithium liquid Ion powerbook battery causing great harm. According to the charge and therefore the best time and method of charging standards, in particular for not more than 12 hours of super-long charge. Typically, the statement introduced mobile phone charging method is suitable for the mobile phone standard method of charging.
In addition, the lithium battery in the phone or battery charger will automatically stop after a charge, there is no electricity nickel charger for 10 hours the so-called “trickle” charge. In other words, if your lithium batteries in full, on the white charger is also sufficient. And we can not guarantee that no one battery charge and discharge protection circuit features and never change the quality of safety, so your batteries will be in the long-term hovering on the brink of danger. This is also another charge against the chief reason.
In addition to certain mobile phones, the charge for more than a certain amount of time, if not remove the charger, this time not only to stop charging system, will be the beginning of discharge - charge cycle. This is perhaps the manufacturer has its own purpose, it is clear that on the phone and battery / charger is the life span of a negative. At the same time, long charging would take a long time, often at night, and to our country’s power grid situation, at night in many parts of the relatively high voltage, but also volatile. Said earlier, the lithium iBook G3 battery is very delicate than nickel in the electric charge and discharge aspects of fluctuations in the capacity of resistance is much less, so this brings additional risk.
In addition, can not be ignored other aspects of a lithium battery that is not the same for over-discharge, over-discharge of lithium batteries is also very unfavorable. This leads to the following question.
2, in normal use when the charge should be
In our forums, often see this as the number of charging and discharging is limited, so should the cell phone battery power used up as much as possible and then charge. But I find on a lithium-ion battery charge and discharge cycle test table, on the life cycle of figures is as follows:
Life cycle (10% DOD):> 1000 times
Life cycle (100% DOD):> 200 times
DOD is the depth of the discharge of which the initials.
Can be seen from the table, the number of rechargeable and about the depth of discharge, 10% DOD at the time of the life cycle than 100% DOD’s a lot longer. Of course, if the actual charge equivalent to the total capacity of the relative:
10% * 100 = 1000
100% * 200 = 200, which is the complete charge and discharge, or better than some, but in front of friends do say that some of the amendments: Under normal circumstances, you should have a reservation in accordance with the remaining battery power and then run out of charge to the principle Charge, but if your battery is expected in the first 2 days you can not
To adhere to the whole day, should start on time charge, of course, if you are willing to carry another charger to the office when Bielun.
And you need to charge in order to cope with the anticipated upcoming busy communications will lead to an important event, even if the iBook G4 battery is still
There are a lot more than power, then you just charge ahead of time because you do not have a real loss “1″ sub-charge cycle life, it
Is the “0.x” times, but often this will be a very small x.
The remaining battery power and then run out of charge to the principle does not mean that you go to the extreme. And charging the same length of a widespread,
“As far as possible the cell phone’s battery run out of power, it is best to use automatic shutdown.” This is only a matter of fact on nickel batteries,
The purpose is to avoid occurrence of memory effect, unfortunately, it is also spread of lithium batteries on this. It has been because the cell phone PowerBook G4 battery had
Low warning appears, do not continue to use the charge has been used in automatic shutdown of the case. The outcome of this case, the phone in
Later in the boot of charge and there was no response, had to give customer service overhaul. In fact, this is due to the battery as a result of the excessive discharge as a result
Low voltage that does not have the normal charge of the boot and conditions.
3, Li-ion battery for mobile phones boils down to the correct approach, I lithium batteries used in mobile phone charging and discharging of the most important tips are:
1, in accordance with standard procedures and charging time, even before the three to do so;
2, When the phone prompts when electricity is too low and should start charging as much as possible in a timely manner;
3, lithium batteries do not need to activate the special method, in a normal cell phone use in lithium batteries would be natural to activate. If you insist on spreading the use of “three times before the 12-hour long activation charge” approach, in fact there will not be the effect.
As a result, all 12 hours long pursuit of the lithium iBook G3 battery and rechargeable cell phone used in automatic shutdown, are wrong. If you are used to be in accordance with the wrong done, please correct in a timely manner, perhaps not too late.
Of course, cell phones and chargers to protect themselves and control the quality of a good circuit, for the protection of lithium batteries or have guaranteed. Therefore, understanding the rules of the charge is the key, in some cases also may make some concessions. For example, you found your cell phone the night before bed charge, you can also start charging before going to bed. The crux of the matter is that you should know what is the right thing to do, and not in accordance with the deliberately wrong to do.

TDK at the “CEATEC JAPAN 2008″ on display at the use of organic pigments and zinc oxide (ZnO) flexible dye-sensitized solar cells. The company’s measurement of self-conversion efficiency of 7.9%. In the type of dye-sensitized solar cells, this is a very high value. The solar cells are bright colors, including red, yellow, green, purple, and so on, the company disclosed in Ju Peng with a live demonstration of the power generation.

In the type of dye-sensitized solar cells, this is a very high value. The solar cells are bright colors, including red, yellow, green, purple, and so on, the company disclosed in Ju Peng with a live demonstration of the power generation.

TDK earlier in the CEATEC exhibition also had dye-sensitized solar cells. The difference this time is: (1) and the bottom of the packaging material by the glass has become a flexible plastic conversion, (2) test module conversion efficiency from 7.2% to 7.9%, (3) to adopt more Module size and is equipped with the Ju Peng, (4), through the replacement of pigment to achieve a richer color, and so on.

TDK based on the use of organic pigments and ZnO solar cells, lower-cost pigment, the temperature control process in the plastic will not melt temperatures of up to 80 ℃. The company created the low-temperature process can make use of the advantages of using plastic floor of the solar cell.

The manufacturer of the battery cell and test tone, focus more on product conversion efficiency. The display of solar cell modules is even more focus on the bright color degrees. TDK did not open for each color conversion efficiency of solar cells, but “other than the green IPCE (photoelectric conversion efficiency) for the maximum 80%” (TDK), is relatively high. IPCE is that a specific wavelength of a single photon energy conversion efficiency values.

To display the concept of “environmental protection, family DC”

TDK will be the CEATEC exhibition concepts as “green DC family (Eco-house)”. The aim is to install renewable energy such as the DC power generation system, the output current is converted to non-AC, but the direct supply to the home use of direct current operation of household electrical appliances. As a result, in addition to a live demonstration at the Che Peng on solar power, but also a display of household wind power installations.

Third, the Internet giant Google, Microsoft, Apple in operating systems, browsers, smart mobile phones in the field to start the real battle for hegemony

September 8, 1998, Google in a garage in the United States was born, and after 10 years, the company has become a market value of monster 160,000,000,000 U.S. dollars, its market value at the front of Microsoft and IBM, which Google’s reach Height, respectively, by a quarter of a century and three quarters of a century.

Even so, the “fast track” the Google did not actually want to slow down last Tuesday, the search engine company released a browser product Chrome, so Microsoft suffers opponent, fired a heavy again.

Microsoft’s growth in the course, Novell, Netscape (Netscape), Real Network, Sun (Sun Microsystem), and so have the names of great glory, has become a stepping stone. But Microsoft’s business in the chain, whether it is Google or Apple in the manufacture of “big trouble.”

Tripartite structure has taken shape in the future has become complicated and confusing.

“Computing cloud” over the next run-off

Chrome aimed at the birth of Microsoft’s core market. In the browser market, Microsoft is dominant, IE browser share to 73%, Firefox (Firefox) accounted for 19%, while Apple’s own Safari as the global research and development of the popular iPod, iPhone and the iMac, have also been 6% share. The market had nothing to do with Google, but now it wants to share this laptop battery .

“What we need is not just a ‘browser’, but a modern platform, you can browse the Web, use Web applications and to support those who have just started the function.” Google vice president of global product management, engineering director of R & D Saunders. Pike Hai (Sundar Pichai) explained that such a release Chrome background.

Today, the development of Google Docs, calendar and other network “cloud computing” features of Google, users have to enter the network platform - the browser market, make a difference.

Google’s supporters believe that Chrome simple convenience, the extension of Google’s style, there is no “rogue” embedded in the toolbar or other products, for the sake of the future users of products; However, some features that are not propaganda The so strong.

“And not for Apple Computer’s browser version.” New York City software engineer at the University of Derek (Derek) said, “This is to allow users to use Apple’s not the opportunity to try.” Chrome Although Google drew on the part of Apple Code technology, but the current version of the Beta can not run on the Mac, which is quite popular Macintosh U.S. consumers, is a regret. “This is against their old foe - Microsoft.” Drake told reporters.

In fact, Google is targeting the so-called “cloud computing” the future of the picture. Google considers the future of the Internet users through the functions of all PC functions, and in the “cloud” on the storage of information.

Now, as the most fashionable concept, in fact, Microsoft, Yahoo also acquired shortly after the failure of the case, spoke of his “Cloud”, and IBM, Yahoo and Amazon, they all agree that the “cloud” of the idea, but Not come up with specific solutions.

In the foreseeable future, all released new products and strategies against opponents, Google is to “cloud the future” in preparation for war, in the context of this strategy, the success or failure of the browser market is an introduction, is not The ultimate goal.

Seize the hearts of consumers with laptop battery ?

In the face of Microsoft’s “dilemma” and “retire” BillG (Bill. Gates, Microsoft co-founder of the in-house nickname) has also recently appeared in your field of vision,. And his well-known talk show host Seinfeld (Jerry Seinfield) together, make a determined to improve Vista, and consumers to listen to the voice of advertising.

The ad’s plot Gates is a pair of shoes to the shoe store, met Song Fei, Song Fei and standing on the consumer’s point of view we look forward to running on the computer be summed up as “like a cake, so we work with computers, on the Chi Dangao as comfortable as easily. ”

And Microsoft’s new Vista product obviously runs counter to the original intention of the above. “Vista for the first time trial, that it is fundamentally not worth the original Windows Update.” Harvard Business School’s David. Yafu (David B. Yoffie) said that the slow speed, a huge invasion and occupation of hard disk space, there is no obvious improvement and application of experience, in addition to feeling more like Apple’s operating system, XP is not as stable and reliable system, a time full of complaints against Vista Media and networks.

Microsoft’s operating system, the world’s personal computers accounted for more than 90% market share, Apple began MacOS operating system to catch up with Microsoft, the phenomenon of the large number of fans in the Mac market, especially in the United States.

With the Microsoft anti-trust organizations have been repeatedly called in a different situation, Apple is a fashion, consumption, a synonym for the young and future. With Microsoft to provide software solutions, is provided by Apple personal computers, music and mobile communications equipment, software, Web browser vertical product program.

“Vista is the product of the market situation than six months ago still difficult.” Market, Microsoft’s product strategy and marketing senior vice president, Bill. Wei Jite (Bill Veghte) has to admit that. In the original internal Microsoft, Vista is a repeatedly postponed the date listed on the product, Microsoft Chief Executive Steve. Ballmer Vista in the final after the launch, had emergency Wei Jite transfer window to help the Ministry of products, but also to move out to Gates “put out the fire.”

Wei Jite is summoned to ease Vista’s “The market does not apply disease,” Microsoft’s Seattle headquarters building is also a special “retail experience centers” to test a variety of innovative applications in the consumer response. These creative ways to come from Microsoft’s competitors - Apple.

Apple as a consumer feedback attached great importance to the company, Microsoft’s competitors began to learn to make a new model of R & D - starting from the consumers.

“Smartphones” who is going to hit

Google released the browser might be expected, and the other a “blockbuster” I do not know when that will debut the “Gphone”.

The electronic communications market, Google is not the traditional areas of competition, but “walk in the clouds” in the future, and easy to carry mobile communications products, companies strive to be sure that the focus of one of the BlackBerry and iPhone in this area is the best .

“Silicon Valley engineers have also circulated a statement, Gphone in the future may not be an entity of the mobile phone, but a standard format for the norms of the mobile phone network links and network services.” Years of work in Silicon Valley, Mr. Meng told reporters.

Smart phone application is clearly the direction of the computer can achieve the full functionality of the existing 30,000,000 users will have a geometric growth, such as the 2008 date, the growth rate of users in North America compared with 77% increase over the same period last year.

Many manufacturers in this market, mouth-watering, even for a long time to do outsourcing business in Taiwan-based High Tech Computer related to Google co-operation to release the first smart phone products Android. Coincidentally, the nation’s largest Phone network operator Verizon Communications also recently with Google on a long-term cooperation projects with the objective of mobile phones in the first breakthrough in the field of search.

Prior to this competition, Apple and Google has always been to fight Microsoft, Google, but once the “meddle” smart phone market, and Apple’s iPhone will launch direct competition.

Google and Verizon negotiations with the outstanding issues, mobile search is the issue of storage of information, advertisers have been promising such a powerful force in the search, Verizon has also put particular importance on this part of the ownership of information.

“Google’s ambitions are too obvious, Gphone.com a few years ago, Google was found to be registered.” Wang told reporters. In the Google search engine has become the PC monopoly, aimed at mobile devices at once the search engine market.

In the last year of the American public survey, 63 percent of people choose not hesitate to enter the field at the site Google search, 34% of the people who sentimentally attached to the “myth” Yahoo. However, if the Gphone born Heng Kong, iPhone how to deal with, who took to the smart phone’s hegemony, will become the next Silicon Valley that hot topic.

1, lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V (4.1V, the batteries under the brands have different designs). (Li-ion batteries is the norm: lithium ion secondary battery)

2, to the requirements of lithium-ion rechargeable laptop battery (GB/T18287 2000 norms): First of all, constant current charge, that is, a certain current, and battery charging voltage as the process of gradually increased, when the battery terminal voltage to reach 4.2V (4.1V), Constant change Charge for the charging voltage, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process to continue to gradually reduce, when reduced to 0.01C, that the termination charge. (C batteries based on current nominal capacity of a control method that, if the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not mAh, 0.01C is 10mA.) Of course, that standard is 0.01 C5A, here I simplified.

3, 0.01C why that was the end of the charge: This is a national standard GB/T18287-2000 provided as well as the discussions. Previously it was generally for an end to 20mA, the Ministry of Posts and Telecommunications YD/T998-1999 industry standards provided for in the same way, that is, no matter how much battery capacity, to stop all current 20mA. GB 0.01C provided help to more full charge, through the identification of a party manufacturers benefit. In addition, the national standard provides for the charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours, and that the end of the charge. (No problem, the quality of the batteries should be 8 hours to reach 0.01C, the poor quality of the ibm battery, wait and meaningless)

4, What is the difference between battery 4.1V or 4.2V: consumers do not have the distinction, depending on batteries manufacturer of the product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is the basic 4.2V, but there are exceptions, such as Tianjin is the power of God 4.1V (but also by a 4.2V).

5, the rechargeable batteries of 4.1V to 4.2V happen: will increase the capacity of the battery, with a good feeling, and standby time, but will reduce battery life. For example, the original 500, reduced to 300. By the same token, to the 4.2V batteries have been sufficient, it will lower its short-lived. Lithium-ion batteries is very delicate.

6, since the battery inside a protective plate, we can rest assured that it had: No, because the board to protect the cut-off parameter is 4.35V (this is good, the bad to 4.4 to 4.5V), protection of the board is to meet in the event, If every time charge-off, the ThinkPad R51 battery will decay quickly.

7, much of the charge current is appropriate: In theory, the smaller of the more beneficial to the battery. But you can not order a battery charge, such as 3 days now. GB provides low-rate charge is 0.2C (standard arbitration charge), but also to the top of the battery capacity of 1000mAh, for example, is 200mA, so we have this battery can be estimated more than 5 hours to full charge. (MAh = current capacity mA × time h)

State technical supervision departments to identify capacity lithium-based high-rate charge of 1C to 0.2C low discharge rate, time to work out the value of capacity, the number of Test 5, 1st capacity to reach the end of the trial. (5 is the chance that if the first pass a test on the back of the 4th does not) allow for testing before the first cycle in advance, in order to 1C is the current charge that 4.2V to cease, and not behind the constant pressure to 0.01 C process, but not 14 hours.

8, Li-ion batteries can withstand much of the charge current: factory tests can be very high, but the elevation ratio requirement for the country 1C, also above the cell, for example, more than 1 hour can be filled. Such a charge current, battery can bear it? For the current lithium-ion batteries, is the only Xiaoyi Si. There are no national standards for the Chargers, enforced by the Ministry of Posts and Telecommunications is the industry standard YD/T998 1999 / 2, which provides for the current charger not to be more than 1C.

9, what is provided for in life: to put it simply refers to the ThinkPad T41 battery at 1C charge N after, 1C discharge, the capacity dropped to 70% at this time of the N is the life. Is not to say that 300 can also be used, the 301 can not be used. GB provides life shall be not less than 300. We usually do not detect the use of the conditions so harsh, life will be longer.

Along with the digital Blasting industry growth, Ni-MH battery for its benefits, environmental protection and the advantages of the players get more and more popular and bulk purchases, from the traditional use of small household electrical appliances: flashlights, clocks, lamps, radios, tape recorders, shaving To be a knife, washing phone, hair dryer, beauty, electric toothbrushes, and other widely used to our new MP3, PDA, WALKMAN, a digital camera, voice recorder, a video game, digital cordless phones and other products to China. A lot of friends through the Ni-MH laptop battery and battery box CRAB brands, with labels for different products for more than a match for the purchase of nickel-metal hydride batteries.
A number of domestic and foreign manufacturers continue to introduce the use of nickel-metal hydride battery of new products we have to speed up the procurement of heat, of course, her unique “quality”, such as energy density, the number of charge, a small memory effect, non-cadmium mercury and other harmful Metal advantage of a series of achievements have a nickel-metal hydride batteries in the market rising.
With everyone in the hands of the nickel-metal hydride batteries in the number of continuous increase in the use and maintenance of science gradually into the line of sight of the concern in the past. As we all know, brand Ni-MH battery life according to the official line is that the charge can be 500 -1000 times, in fact this is a good value, often less than this life. But as long as a reasonable use of the charger, a more in-depth understanding of the Ni-MH battery, we can still do her “longevity.”
1. Under normal circumstances, the new nickel-metal hydride batteries contain only small amounts of electricity, we must first purchase and then charge for use. However, if the battery factory relatively short time, the electricity is enough to recommend the use of first and then charge.
2.’s Purchase of the new nickel-metal hydride batteries generally go through 3-4 times the charge and the use of performance in order to play the best, a lot of friends met for the first time charge of the minor problems, such as charging for the first time after the shooting did not imagine the amount of PP You so much? In the 3-4 times charger and use after all be solved.
3. Although the Ni-MH battery memory effect of the small, we still recommend the use of as much as possible every time after the end charge and is full of one-time, I will not be sufficient for a moment and then charge. However, this “longevity” Oh, that’s important.
4. Rechargeable inspiron battery, charger should pay attention to the surrounding heat, too, what with the fan blowing deliberately not necessary, but bearing in mind that the charger is not to put too much around the debris. Ordinary users in the use of batteries, the batteries are not the exclusive use of storage bag; users to replace the battery after the customary battery placed at random, regardless of whether or not the release of the place clean, damp. The consequences of such a battery is easy to dirty and easy contact with the metal , for example, and other key contacts easily damp, and these are the enemy of batteries. : Users should set up a special cell to place, maintain and clean the battery. In order to avoid problems such as loss of electricity to keep the battery at both ends of the contact point and the internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.
5. Not for a long time, remember that the battery from the battery out of position, under dry conditions recommended card into the battery box, to avoid short-circuit the battery.
6.’s Not a long-term nickel-metal hydride batteries will be stored in a few months later, the battery into the nature of a “dormant” status, significantly reduce battery life. If the nickel-metal hydride batteries have been placed for a long time, I suggest you first slow to carry out sufficient charge is appropriate. Here is another key issue involved: Ni-MH battery, the battery is fully discharged and then save, or save live? These two very different point of view, it should be adopted? Many people believe should be the former, but I think a more reasonable to preserve the battery charged. Because: It has been tested, Ni-MH battery kept charged is the best conditions to preserve about 80 percent. This is because Ni-MH battery self-discharge more (10 percent -15 percent a month or so), if the battery completely discharge and then preserved for a long time not to use, the battery self-discharge phenomenon will cause the battery Over the discharge would damage the battery. Do not believe it? What do you think of buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. : More compared to rectify the wrong point of view, from the start in the right direction maintenance batteries, or else they will backfire.
7. Have made many friends in the post asked how the Ni-MH conduct discharge? The expert asked about the number of batteries, reached the same conclusion to remind friends. Do not try to nickel-metal hydride batteries, rechargeable lead-off put the failure to do so against much larger than their own Ni-MH Inspiron 8200 battery memory effect!
8. Multimeter battery is full of self-test or not. General in charge Ni-MH battery, 1.2V voltage below the normal voltage in full after about 1.4V. We use this to determine, it is easy to judge the status of the battery.
9. Charger can be broadly divided into fast and slow-filling charge. Slow flow of small charge, usually around 200mA, such as our common charge current is 160mA or so. Her charge for a long time and charging the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but the charge would be sufficient enough and does not hurt the battery. Fast flow usually charge more than 400mA, charging significantly reduce a lot of time ,3-4 hours you can get, and everyone’s favorite to win. Many types of fast filling, the prices vary. So often we all have doubts, are filling fast, and why the price is a big gap in it? Good charger in particular are filling fast with a good anti-over-charge protection, for example, we the Panasonic common charger Need BQ 390 in this regard was especially outstanding, excellent software, chip design capabilities in the battery charge, Also quick to charge batteries on the injury down to a minimum.
10. There is such a conflict: Slow injury is not sufficient battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the world is the best surface of the Need for Panasonic BQ390 charger can only be good to reduce the extent of injury , But can not be completely avoided. This contradiction can be resolved is to buy a quick charge and a charge slowly. With sufficient speed and sufficient period of time, for example, at 5, 10, Chong Chongdian slow to switch to one or two. This will also return to the performance of battery-top condition.
11. Batteries are generally used Inspiron 8100 battery, that is, 4 or 6 series, this time to maintain the balance of each cell is very important, otherwise, because of a battery problem affected the entire battery pack. First, the battery capacity to ensure consistent, it is best to choose the same brand of the same type of battery at the same time to buy. Then, to keep the internal battery power, said simply, is that the battery power is either full or empty. If there are more cell group composed of a number of batteries, you can try to “select” look. That is specific to capacity, similar to parameters such as voltage battery series into a single set of batteries, due to inadequate conditions, under normal circumstances, let us test after the end point of voltage and power good voltage washed it.
12. To talk about the final charge and discharge.
The high-grade NI-MH battery charger using a detection-DELTA V battery voltage to determine whether the battery is full. When the battery voltage discharge curve and a little bit similar to the beginning of a more rapid rise, followed by the slow rise until sufficient good, fast start and voltage drop in the rate of decline is not great. Before commonly used nickel-cadmium batteries are also similar, but the decline in the speed and range than the NI-MH are great. The largest number of chargers on the market (that’s less expensive) is often used in value-charge pressure, such as Po-old GP is the 1.4V charge voltage value, that is, into the battery when the 1.4V voltage in the absence of the poor, charging the end of . Such an outcome often is not full of batteries, especially older ones, some of the batteries, due to increasing resistance, the real increase in Inspiron 4000 battery on a lower voltage. This charger current and often smaller, often have to charge more than 10 hours. The use-DELTA V automatic cut off of the charger, because it can accurately control the charging time, it can be more reliable to use the current charge. Current nickel-metal hydride rechargeable batteries for the damage we did not imagine the stakes, the opposite, the use of DC now, more high-current charge. The first is a matter of time, do not have to speak. Then, Ni-MH battery has a characteristic that you charge the greater the current, it can release the greater the current, DC power is a tiger, not a small current, relatively speaking, therefore, the use of relatively large Current charge is a wise choice, can increase battery _ clean. 5, the general charge current should not exceed 1.5C, C for the battery capacity is 1000MAH batteries, not more than 1.5A. I normally charge for use of 0.5C (my current adjustable charger). Discharge, under normal circumstances, DC after the black screen will be able to take charge of, NI-MH little memory effect. But after a period of time, as well as to balance the battery cell activation, to control the discharge of the Inspiron 600m battery voltage termination. NI-MH battery voltage of the termination of 0.9V, the discharge time careful not to over-discharge, on each battery 0.9V when you can stop the discharge. NI-MH battery has not tough nickel-cadmium batteries, the charge had been released and are more sensitive to high temperatures. Charge-discharge temperature. In general, do not let the battery temperature higher than 45 degrees. The battery is full, the batteries will be fever, a high current when the temperature should be about 42 degrees and not more than 45 degrees, otherwise life will quickly reduce the battery internal resistance will increase. In addition, the battery charge after a high temperature, cooling, and so only after their charge, the money would also charge the battery cooling, and so on. Not long after the re-use, the best sufficient to reactivate the battery release several times. The use of normal time to pay attention to maintaining the integrity of packaging paper, there can not be broken in order to avoid a short circuit. Do not tempering the impact of the battery, so do not fire.

What is the use of laptop batteries and maintenance of the taboo? Maintenance of notebook batteries in the end not to be pulled out books, out of power if the how to do? If the laptop battery maintenance of good words to use up to how long? See below, it will know.

Laptop battery life is longer, often dissatisfied with the charge, or even show damage, it must use some attention to the maintenance tips: Whether you use the laptop’s lithium notebook battery or Ni-MH battery, battery power as much as possible to use the basic And then do charge (less than 5% of electricity), which is to avoid the best way to the memory effect. In fact, the lithium-ion battery has some memory effect, Ni-MH battery is more than just a lot smaller. It should be noted that, however, charge, as far as possible to avoid too much time, the general control within 12 hours.

Battery life of notebook batteries, not by the total length of time, but by the charge and discharge to determine the number of times. Here is the notebook maintenance. If the battery will always be loaded to a notebook instead of taking down, even if the machine shut down and remove AC power, the battery would not like to imagine what it has been full of electricity when the state. As the laptop battery in the battery in the integrated control circuit, so even if the computer is shut down when power is power. As the one connected to AC power, will begin charging the battery, when turned on or off the power when your notebook battery will be recharged repeatedly and discharge affect battery life.

To this end, the use of external AC power supply when it is best to unplug the inspiron battery, or notebook battery for a long time in a state of fever have an impact on their life. To maintain the battery, do not have long-term, at least 12 months a red discharge in order to ensure its activity. In the custody of the battery when there is a need to pay attention to. At present, the vast majority of notebooks used in lithium-ion battery for a long time, if not in use, often prone to excessive discharge, may no longer be able to charge batteries for notebooks. In order to prevent the excessive discharge, in a state of semi-charge save in cool dry place, and then once every six months, and then the necessary and sufficient electricity to half of the state.

In addition, the impact on battery life books of factors including the use of the environment temperature (30 ℃ suggested that the use of the following), storage batteries and the battery temperature suffered shock, such as size. Notebook batteries in use for some time would be after the aging (how maintenance is the same), the specific performance of the resistance is bigger in charge when both ends of the voltage rise faster, so that was easy to charge control circuit has been judged to be full of , The natural capacity is lower than before. Notebook battery is a correction to deal with the aging batteries effective way to a small number of notebook batteries have the exclusive use of correction software. If your laptop does not discharge the exclusive use of software, so the battery can be in accordance with the following steps for maintenance:

● screen saver will be banned;
● In the Windows power management will power scheme is set to “always open”;
● alarm at the tab will be “insufficient power warning” is set to 10% of the operation is set to “operate”;
● will be “a serious power shortage alert,” set to 3% of the operation as a “wait”;
● the screen brightness to the maximum;
● confirmed that all the windows closed, and save all the data before work;
● confirmed that the Inspiron 8100 battery charge in more than 80%, pulled out all external power supplies and equipment.

Discharge after the end of the notebook will automatically shut down after the power supply will be planted to allow notebook charge, the process can be repeated 2 to 3 times to enable the continued low current battery discharge, which discharge in the state of our day-to-day use is not possible Achieved, the effect of the discharge and those dedicated basically the same software.

Q: What kind of notebook can provide a longer battery life time?

DELL engineers: only low-value CPU frequency is wrong thinking to choose, because the selected components such as LCD can achieve energy-saving, and CPU can be dynamically adjusted according to application frequencies, it can not value the “Ultra Low Voltage.” In comparison, high-capacity battery configuration of the mainstream Centrino notebooks performed well, if conditions allow, can be equipped with the best recommendations of the second block the use of batteries. Usually use the same battery, the time to go out with the original Inspiron 4000 battery . In fact, to buy a piece of notebook batteries are not expensive, you can find those brands are specifically to help manufacturers who wish to purchase. Those manufacturers because there is no pressure on the brand, so prices less than the general.

2 weeks, informed sources in the Taiwan general manager of HP’s Personal Systems Group has been appointed Chen Jinghong Dopod CEO, the former head office Xu Weide COO. In this way, Dopod again in the outside world knowledge Huanshuai lightning.

The new CEO took office

“Dopod Chen Jinghong in the Shanghai headquarters has to go to work, the company in charge of overall work,” the Huanshuai, Dopod in-house staff to be confirmed Latitude D600 battery .

It is reported that on September 1, the board of directors formally appointed Chen Jinghong since September 1, 2008 has served as Wuhan Dopod Communication Co., Ltd. Chief Executive Officer (CEO). This is the second HP Personal Systems Group General Manager of Greater China, Song Chong is switched HTC, as the global business executive vice General Logistics Department, the Department of Hewlett-Packard executives to join another HTC’s e-business.

Chen Jinghong should be loose in the village are Hewlett-Packard Taiwan at the time of his subordinates. 4 and a half years ago, Song Chong is from Taiwan Asus battery  , general manager of HP’s personal systems he moved to China over China, general manager of HP’s personal systems, Chen Jinghong was only 37 years old, from a number of candidates able to compete successfully, Taiwan took over HP Personal Systems Division, General Manager , Hewlett-Packard Taiwan also reached the youngest general manager in the history of the record.

Chen Jinghong as the Dopod and CEO John song is not clear is how much relevance.

Xu Weide remain COO

This is the Dopod Huanshuai once again set up over the past few years. Dopod brand is “returnees” Yang Xingping single-handedly set up, but in March 2006, Yang Xingping president was removed from office, honorary chairman of the company name, company chief operating officer (COO) from David Lee on March 15 Yang Xingping officially take over duties from David Lee took over later. In May 2007, Dopod also announced that David Lee transferred, switched to Asia van den Bergh, e-business market operations, took office in 2006 Dopod China, Xu Weide COO of part-time CEO.

Chen Jinghong, the new CEO had been e-van den Bergh, will take over the Greater China business, but in fact served to Dopod.

Dopod insiders said Xu Weide retain the original post, which will focus on sales and channel management, Chen Jinghong is in charge of overall work, the company will continue to maintain relatively stable.

Huanshuai unexplained

The Huanshuai unexplained, however, when he was in office Xu Weide Dopod still full of riveting enough.

On the Dopod, 2007, is listed on the New year. Since 2002 in China since the founding of Dopod, Dopod listed a total of about 26 new models. But in 2007 Dopod listed on the 11 new models. Therefore, we can imagine in 2007.

At the same time, Xu Weide when he was in office for Dopod planning to carry out the product line is divided into five main categories: P series phone navigation, S series of stylish handsets, D series of business aircraft, E series of mobile application industry. It also set foot in a broad Dopod CDMA and TD-SCDMA mobile phones, Dopod these are beneficial to the long-term development.

However, parallel imports and the proliferation of smart phones in the field of competitors increase in long-standing issues such as Dopod, in the short term can not be resolved for any new CEO is a severe test.
