just myself

Sometimes we go out and meet the urgent, just call the phone, on the tips of electricity shortage or interruption of the call, then again no place to recharge, telephone and must get through, how do  I think many of my friends also may encounter, if you really encounter such a situation, I can tell you the way to an emergency, can facilitate the use of battery to the original call or up to 20 minutes long, to address you The urgent need.

    If you encounter such a situation, you first Buyao Ji, here, you can open the phone the back, took out the battery, you can find in the phone Apple battery , generally there are three or four electrodes, you can take a small paper, The middle of a battery or two with small paper covered with electrodes, or covered with adhesive tape to stick, and then fitted with batteries, open the phone, the phone will display here may be “illegal battery” tips, you can Buqu Guan him, only To enter the surface of normal keys to call again, the general encountered such a situation, can call up at about 10-2 to the solution you need.

    Cell phones generally have three or four electrodes electrode, the middle one or two electrodes to test a battery, power supply for the electrodes on both sides of the pole, battery power, through the phone to detect whether a measurement of electricity, if you use plastic Paper or paper cover the test is, can not test the phone on VGP-BPS5A battery power, then you can call emergency, in most cases, mobile phone battery voltage dropped to 3. 6 V below, your phone will be prompted to lack of electricity, to tell you the phone To be charged, but cell phones are used in lithium, a nominal voltage of 3. 6-3. 75 V, due to a different cell phone manufacturers, set up by the threshold voltage is also differentiated, lithium, as long as the voltage of not less than 3 V, The,VGP-BPS4  batteries are not what effect, if the voltage is lower than 3 V, the phone would not work, so use this method of emergency only when necessary, can be used with a, but there is one point to note that after use, must be paper - Remove, or, charging the phone charging less than the same test, causing opponents to misjudge.

    Impression on almost half a year before, ZPower has just claimed that they had laptop computers with several contract manufacturers, is expected to start in August this year a new supply of silver zinc rechargeable laptop battery  (Silver-Zinc battery). However, the latest news that all this is just a hallucination, because ZPower this week in the Intel Science and Technology Forum, updated the shipping date to 2009 in one day.

ZPower as the silver zinc batteries that seems to many of the benefits. It can not only provide a more modern mainstream of the lithium  PCGA-BP2NY battery has a high 40 per cent of the electricity, and also offers a more stable chemical properties (that is less easy to see the pyrotechnics show passion performances). At the same time the whole PCGA-BP2R  battery have up to 95 percent of the material can recycling and reuse, not only to repeat the use of the valuable resources, coupled with ZPower provide an additional discount replacement of the old plan, users can save a lot of financial expenditure.

So » Now only hope that the new time will not be another dream.

Germany in the World Cup two years ago, RFID electronic tickets to enter people’s vision, although it difficult to effect the actual use of that perfect. Due to technical and cost reasons, the last Athens Olympics and did not use the technology, the Beijing 2008 Olympic Games the first history of the use of RFID electronic ticket laptop battery systems in the ground, the Chinese people will do better than the Germans? » Many people are waiting to see, this article will lead you to close virtual experience this new technology.

Energy to power batteries for electric vehicles is considered the 21st century green project, it will be the emergence of the development of the automotive industry into a new field. At present, the core components of electric vehicles in the motor, controller and three body parts in the theory and technology have been more mature laptop battery, while the other two major components batteries, chargers also the development of electric vehicles can not meet the requirements of a number of theoretical and Technical issues have yet to be key, has now become the impact of the development of electric transport bottlenecks.

– August 28, according to foreign media reports, sony battery company in Singapore a lithium-ion polymer battery manufacturing plant will be commissioned this week four.

The investment of 105 million U.S. dollars monthly factory can produce 8 million cell phone batteries, will employ 500 staff. Sony announced last August in Singapore this laptop battery  manufacturing plant construction projects to meet the fast-growing demand for lithium-ion polymer battery. Currently about half of lithium-ion polymer battery used in cell phones, the other half is used in notebook computers, cameras and other electronic products.

Earlier this month Sony announced the next two years raising 365 million U.S. dollars investment in lithium-ion Inspiron 5100 battery production project. The investment will be used in Japan for construction of the new production line and the existing production lines for technological transformation. Sony is expected in Japan, the additional capacity that will allow the company  Inspiron 700m battery units from the current monthly output of 41 million in 2010 to 74 million.

46 million mobile phone batteries, is not a small number, but Nokia is committed to the recall, or a replacement. In case of a laptop battery when not absolutely, Nokia’s the recall or wise. If Nokia phone batteries also wounding the incident or even dead, damaged the reputation of this is not the world’s largest cell phone manufacturers want to see. This person also Diubu Qi. Many battery manufacturers to bring embarrassment, the old laptop battery incident just dust off, handset manufacturers and ushered in the battery on the storm. When the injury continue to be seen in the media, we may be on the phone battery is also the harm caused more than a guard. This handset manufacturers have put new demands, smart phones now have the pop to make phone battery standby time is short to become a bottleneck in the development of mobile phones, today’s incident is unsafe for people to the development of a multi-cell phone a Worried.

The media revealed that the issue of mobile phone batteries replaced by: the use of the exact type of cell users, Nokia will be unified in the global DHL courier to send a new battery. DHL in China are not yet covered the region, Nokia will take other forms, such as express delivery, to ensure that consumers receive a new battery. However, whether the customer how to declare their own ibm thinkpad battery recall in this context, not a clear argument, which is also the test battery English interface, the authors are using the Nokia N70, also belong to the BL-5C battery models in the series, Nokia I call the customer service hotline of China market: 4008800123, but for
Several are not connected, in the final site for the English interface, does not belong to the scope of the recall.

We note that Nokia The recall covers the broad, then, Nokia’s current recall how much it costs » A free replacement battery, at present, BL-5C battery in the market price around 150 yuan, of course, there may be some differences around. Coupled with the courier service costs, a rough estimate, Nokia this Jizhao 46 million mobile phone ThinkPad T42 battery in the cost of around 8 billion yuan, of course, Nokia’s battery may have to lower procurement costs, courier fees specifically different, but in any case, Hundreds of millions of dollars in spending is the inevitable.

It is concerned that Nokia Why should take the initiative to propose the recall of this scale? » This, after all, the amount of money involved and influence still very great. As the world’s largest handset maker, Nokia quality is definitely to be pursued, but it is also based on the fundamental market, if in their own brand of mobile phones, mobile phone ThinkPad T60 battery in the worst affected, can not be tolerated, I am afraid this is Nokia Implementation of the recall of the largest purpose. Moreover, the current Nokia in the world have discovered about 100 batteries overheating, but there is no any serious injury or financial loss was reported.

Of course, we also concerned that the recall of Nokia’s global lead position will not affect » Samsung has surpassed Motorola, will continue to advance » This may not be non-existent, but at least there are still difficult. This is the first notebook PC battery recall there are some differences. It is said that is because Dell was caught in the laptop battery recall, market share has a certain impact, only to surpass Hewlett-Packard, leaped from the world’s largest PC maker. Nokia in this regard and the details are different ThinkPad T20 battery, and the PC market, its market advantage that is not the slightest bit.

In early August, IDC released a report that the second quarter of this year, Nokia’s global mobile phone market is still the boss. The second quarter of the global mobile phone makers sold a total of 272.7 million, representing a year-on-year increase of 16.5%. Nokia’s market share of 37 percent, Samsung and Motorola’s market share was 13.7 percent and 13 percent, followed by Sony - Ericsson’s 9.1%, LG’s 7 percent. As Nokia’s market share obvious advantages, so the recall of its impact should not be great. Although we have to pay the cost, but the market share of the impact of that change little. Moreover, the recall-based Matsushita also pay a fee.

It is far-reaching implications is that Nokia will be the recall to the opportunity ThinkPad T22 battery to Apple iPhone » Despite the current sales can not make the iPhone Apple ranked out of the big cell phone manufacturers, but it has prompted competitors to improve product design and user interface. Apple can even enable handset manufacturers to cell phone operators constitute the dominant position of greater challenges, because the iPhone marketing craze to force consumers to be more mobile as a fashion rather than practical tools. At present, Apple’s iPhone has shown a sales Wang Shi, when caught in Nokia cell of the storm, this new mobile phone manufacturers, it is an opportunity. Of course, this opportunity could be to enlarge the number of times it is very difficult to say, after all, Apple iPhone market development strategy there is still great limitations. There is no doubt that Nokia’s recall, is to make its brand a stronger market credibility and appeal, after all, the world’s first mobile phone brand is not Langdexuming.

In the use of small portable products, high energy density of modern cell technology to power applications throughout the rechargeable laptop battery voltage discharge and high efficiency within the scope of work. This will require 3.3 V bus voltage, lithium ion and lithium polymer battery-powered system brings design challenges. In particular, is 3.3 V bus voltage need to provide more than 0.5 A of the load current, more so. Although the buck converter with high efficiency will be good at 2.7 ~ 4.2 V lithium-ion battery voltage into the lower output voltage (1.8 V), boost converter can efficiently generate a higher output voltage (such as 5V), but the two converters are not always produce 3.3 V bus voltage. Single-ended primary inductance converter (SEPIC), a cascade boost and buck converter topology, and so can be used for battery power, but by low efficiency, high costs, an increase of the board area, a few more devices and design complexity Higher shortcomings of the problems.

Single-or two lithium-ion batteries are usually used 5 ~ 9 V of the AC adapter charge. Allow DC / DC converters used directly to replace the ibm thinkpad battery, AC adapter, batteries shorten the time. Of course, this requires converters can not only to the minimum input voltage of the battery to work, but also able to increase the input voltage. Traditionally, battery-powered handheld devices draw power directly from the battery, even when the battery charge is the same. This type of DC / DC converters also need a very low quiescent current, or to idle in standby mode save battery power.

Ground single lithium-ion ThinkPad T22 battery-powered handheld devices provided in the 3.3 V power rail is a complex problem, many companies have provided solutions, the transit of Stuart’s LTC3785 synchronous buck - step-up switching regulator DC / DC controller is one of them. Its proprietary buck - Boost topology requires only a single inductor, will be able to use higher, equal to or lower than the output voltage of the input voltage to the high efficiency of fixed output voltage. LTC3785 to 2.7 ~ 10 V input and output voltage, is ideal for single or two or lithium polymer lithium-ion batteries, nickel-hydrogen or alkaline metals, nickel-cadmium or alkaline batteries. This highly integrated controller to use only a few tiny external components, with many programmable features, such as soft-start, switching frequency and current limit threshold.

Efficiency curve as shown in Figure 1 circuit in sync, 4 switch buck - step-up DC / DC converters used in LTC3785 controller, and by 2.7 ~ 10 V input voltage to as high as 96% of the efficiency of a fixed 3.3 V/3A Output. LTC3785 provide all N-channel MOSFET gate drive for the use of low RDS (ON) single package and more power switch technology ThinkPad T23 battery to provide convenience. Its proprietary topology and control structure of the MOSFET RDS to detect forward and reverse current limit, to achieve unparalleled high efficiency. To improve the accuracy of the current limit, can use the sense resistor. In addition, LTC3785 in a burst mode (Burst Mode), when the light load quiescent current to less than 100 μ A, which extended battery life of portable applications is essential. LTC3785 also in the stands with real output disconnect the ability to ensure that the battery system and the load off.

     Hokkaido mountain-Nomura Co., Ltd. main business is producing a laptop battery  scrap processing and waste handling fluorescent lamps, 110 workers. This is due to built here in Japan found that the first water Silvermine. Nomura-annual production of waste from the acquisition of 13,000 tons, and discarded batteries of the nation’s 20 per cent of the collection method is 93 per cent of environmental protection through non-governmental organizations to collect, seven percent of the manufacturers through the collection. The operations carried out in 1985, to purify the volume has been increasing. The past, the recovery is mainly one of mercury, through high-temperature (600-700 ℃) incinerator burning of the mercury emissions rule out the collection, but Japan has no mercury-containing batteries, Toshiba battery  on the main recovery of the Tieke and “black” raw materials , And the development of secondary products manufacturers, such as the one product can be used in TV picture tubes. To deal with the cost of 80 yen / kg, the profit depends primarily on the production of waste batteries fees charged by the former (mainly manufacturing plant) and secondary use of the value, of which the latter is the key. Asus battery recycling occupy much space, Nomura is a middle-private enterprises, the Japanese government it has not invested a single penny, but Battery Industry Association of Japan has provided great help, and major Japanese manufacturers to coordinate some financial compensation. The handling capacity of up to 16,000 tons. In addition extraction of spent fluorescent lamps up to 40 tons of mercury a year, while Japan has only one year’s demand for 20 tons, and in this regard can be completely recycled, but also to ensure that its profits.

Other lead-acid batteries such as batteries, Japan could achieve 100% recovery, secondary batteries and cell phone manufacturers are also through active cooperation, in particular the recycling lithium-ion batteries in the lucrative cobalt. Through observation, combined with our country’s actual situation, I think at present is to resolutely implement the first nine ministries on the implementation of restrictions on the mercury content in batteries, as soon as possible to achieve the mercury-free batteries in China, will be a battery of harmful components of the environmental impact of mercury Through the law enforcement industry, manufacturers efforts to a minimum, followed through various publicity means to enhance civic awareness of environmental protection, a A3H battery recycling and buried, and establish a waste battery recycling system. There is the state encouraged the use of renewable technology of recycling to achieve as soon as possible after reuse. As for the issue of profits can take a variety of ways such as sharing to the consumers, development of market products, and so on.
