digital batteries

In the new energy vehicle development in countries and regions around the world have been based on their assessment of different options, research the appropriate technology and Laptop battery development and to encourage support for taking a different strategy. In the current situation as a whole, Japan and the United States and Europe has focused on lithium batteries and fuel cells, but our country to take into account the resources and the maturity of technologies, the accent newly released policies on the promotion of nickel-hydride batteries in metal.

Ni-MH battery to become the object of political support China’s current

In our letter of the Department of June 25, the “new energy automotive manufacturing companies and the rules of access management products,” the vehicle, according to new energy vehicles, systems and key deadlines assembly technology, the degree of IBM ThinkPad R51 battery perfection of the national and industry standards, and industrial degree of difference will be divided into initial phase where the development period, three different stages of maturity of the technology and give Management classified.

According to state regulators, the home-products only in the production of small volumes, and only in approved areas, scope, duration and conditions of model runs, and the operational status of all products for real-time monitoring, product development phase allows the mass production only the approved area, scope, duration and conditions of sale, use, and at least 20% of sales of products running in the real-time monitoring, mature products and conventional products for the Dell Inspiron 1300 battery automobile, “the automakers and ad management product even in the sale and use of the same products with conventional automotive .

This means that in China, December 31, 2010, equipped with lithium batteries and hybrid electric vehicles will be limited to the sale and use areas, use nickel-metal hydride battery and hybrid electric vehicles can be sold and used across the country.

Experts believe that the reason why countries are now central to the development of lithium nickel-hydride batteries, metal, the main reason is that the nickel-hydride technology of metals of the hp PB992A battery is more mature than the Lithium, the most abundant mineral resources, the future of new energy vehicles will track better access to the advertising phase.

“Ni-MH – Lithium-Ion battery – fuel cell,” Industrialization Path

In the three commonly used types of car batteries, batteries lead acid to cause serious pollution of the environment has long been out of the consumer applications, nickel-metal hydride batteries, although the marketing of the integrating the moment, but key indicators of laboratory data were lower than lithium batteries, and the theory Basically, there is no room for; lithium despite superior performance, but still can not be guaranteed safety and the relatively high costs have also affected its business.

Experts predict that the new energy vehicles will be in the “Ni-MH – Lithium-Ion sony VGP-BPS5 battery- fuel cell” industry-oriented development path. From the trend of development and rates, and short-term performance can be achieved only with nickel-hydrogen batteries, nickel-hydride technology of metal drums since the most mature in the next three years, will remain the mainstream new energy vehicles, followed by nickel-hydride technology of metals of the lithium and iron phosphate, hydrogen fuel cells, one third of the world, 5-lithium year and will gradually replaced by fuel cells. Battery giant Panasonic and Sanyo also found that lithium-ion battery can be replaced within 2 ~ 3 years, nickel-hydrogen batteries, mainly due to cheaper nickel-safe hydrogen batteries, has reached high production wide. Lithium batteries also need to continue to research topics such as security, so take time business.

According to economic analysis of Japan Fuji mainstream nickel-metal hydride batteries will be able to continue until 2011, but after 2011, Li-ion toshiba PA3465U-1BRS battery will gradually erode the market share of nickel-hydride batteries, metal The agency predicted in 2009 car-use nickel-metal hydride rechargeable batteries in the world market size than the previous year by 23.7% to ¥ 92,000,000,000, but the 2015 Ni-MH rechargeable battery-vehicle market will be reduced to ¥ 55,000,000,000.

Market demand for nickel-hydrogen batteries to save 2-3 years of rapid growth in

Nickel-technology hydrogen fuel cell, and the industry chain to determine their maturity will be a period of time with the coexistence of lithium batteries, lithium iron phosphate cathode material for lithium batteries allows the emergence of performance and cost advantage has been achieved, but stable, production capacity and lack of effective management of the lack of apple A1175 battery testing continues to be a part of the new energy discourage automobile manufacturers, however, batteries nickel Hydrogen-crossed many years of fighting, technical and industrial chains are quite perfect, in a short period of time can form a stable vehicle support capabilities, and therefore can still be a period of time in vehicles new energy and widely applicable.

According to industry estimates, the market for nickel-hydrogen cell is still expected to get 2-3 years of rapid growth over the next 2-3 years, “10 City 1000″ program, the growing popularity of hybrid cars and export markets overseas for nickel and other factors make hydrogen market demand from the Aspire 3000 battery to strong growth, and when the nickel-hydride batteries, metal and batteries Lithium is still Nanfenbozhong when the nickel-hydrogen batteries will usher in a short period of rapid growth.

Among them, China has launched a “10 City, 1000″ How to get the first batch of nickel demand hydrogen battery market. It is estimated that in “10 City, 1000″ program, about 3200-4000 vehicles, new energy vehicles (including buses and cars) using Chinese-made nickel-hydrogen batteries in three years , bringing a total of about 3.5-4.4 one million kilowatts-hour nickel-hydrogen , VGP-BPS2C needs.

Together, both domestic demand and exports weakened in 2012 after the nickel-hydrogen batteries are gradually replaced by lithium batteries.

Maintaining the pace of R & D policy

In the production of automotive Dell U4873 battery business in China with a production capacity of nickel-hydrogen batteries have represented the majority of companies, including Chunlan Group, Ke-Li Yuan, the Torch High Technology, Hunan Shenzhou share Kane etc., which Chunlan Group is the nickel-metal hydride HEV battery power technology, leading market shares in a leading position in the Torch High Technology and Hunan Shenzhou possessed a certain amount of technical base and position market.

As for the lithium battery, most domestic manufacturers are not capable of mass production, but the planning of the corresponding production has been implemented, it is expected after 2010 are capable of mass production .

Experts believe that technological advances, prices for cars in China and business related to the IBM ThinkPad X60 battery in addition to promoting the industrialization of nickel-hydride batteries, metal, more attention should be some of long term, to devote resources to research and lithium battery development, and maintaining fuel cell monitoring techniques to fill a broader energy market new car is ready.

Lithium-ion battery in 2-3 years, although difficult to replace the nickel-hydrogen batteries, however, not to ignore is the future of lithium batteries replace nickel-hydride batteries in the metal abreast of new energy vehicles. From a global viewpoint, Japan is the international motor current energy news and research cell power and application of more advanced countries, Japan has big businesses in automotive and HSTNN-LB31 battery has invested in building lithium-ion power line battery production, concentrated in the 2010-2011 production. Fuji economy as lithium-ion battery will begin in 2011 to gradually replace nickel-hydride batteries, metal, lithium-ion battery, as no doubt the future of consumer technology path.

Today, Japan In addition to switch focus on lithium batteries, the Japanese cars in the development of new energy and use, particularly in the development of fuel cell vehicles and promotion, many faster than expected China’s internal. Some years ago the Japanese economy, Trade and Industry on development of vehicle fuel cell law and the promotion of a calendar, its strategic objectives are as follows: In 2010, the Japanese used vehicles fuel cell to reach 50000; in 2020 to 5 million; 2030, year to universal access to cars to fuel cell.

Some people, against the battery of the laptop is the blood of the body, although not very precise, but the resulting battery cell can still see the importance of a laptop.

I bought second hand laptops have been for some time. When I started with the Laptop battery to supply a laptop for membership to 50 minutes before the time less and less, until eventually work more than 10 minutes. Although couples battery laptop second hand is unrealistic, too (as long as several minutes can be used to prevent a power failure may be caused by data loss), generally used as a UPS. But in fact I am always behind his back, often in places where there is no outlet to use it, so always expect the battery will work as long as possible because it can greatly improve the mobility of laptops.

Spent much energy on the market to find, but always the first wife did not find the battery. Relied on their own notebook batteries have a certain understanding, and repair of certain powers of the device, try to repair itself. The next operation, tools required are: multimeter, soldering iron, pliers, razor blades, pliers electrical tape, wire or a small bulb.

Capacity Restoration Act

Remove the IBM ThinkPad R40 battery from the laptop and discovered that the battery box labeled “Ni-Cd”, “9.6 V 2000mA” the words, indicating that the battery is a nickel-cadmium batteries (rechargeable batteries are worst case), rated voltage of 9.6V, 2000mAh capacity. A total of eight batteries metal interfaces, respectively, from left to right mark (the battery with the label side up) – TTI + I +.

Measured with the multimeter found that the battery has two batteries, the leftmost “-” and the right of the second “+” is a group, the second left “-” and the far right of the “+” is a group. Detection of two batteries are really for no-load voltage of 9.8V, and when the battery is low voltage alarm, after the mobile starts (and one might expect that there should not be too many ‘ electricity)! Concludes: the laptop to start with low voltage alarm goes off automatically after a while, but when the battery is not fully satisfied, it is a certain degree of residual power, while nickel batteries cadmium have memory effect and do not take full charge over time will reduce Dell GD761 battery capacity.

Then sent for two son of heating (which can also change a light bulb or power resistor) connected to each positive battery cell and negative ends (the discharge current can be controlled to 200mA ~ 500mA between the specific capacity the battery must be considered, while all – usually 0.2C ~ 0.5C is the battery nominal capacity of 0.2 to 0.5 magnification of the discharge current), to release the battery power of finished products base and then it stalls multimeter electrical current to 10A and finally exhausted the battery back in the laptop for a normal load. After such repeated four times and found that the hp PB995A battery was able to work more than 40 minutes from time, primarily to meet the requirements of use.

If your laptop battery is a similar situation, according to the above method a try, there may be unexpected pick up! In addition, if your laptop uses a lithium battery, the discharge of the battery cell in a note to be sure to jump the battery box of the circuit, because the only way to achieve good results.

Cell replacement laptop battery

With the method of recovery capabilities can be used to extend the sony VGP-BPS2A battery for some time to solve the problem, in addition to replacing the entire stack outside the (laptop batteries second hand is very difficult to find same model) can also change the core of the battery. But it also requires a better understanding of the knowledge of the battery, which powers the operation stronger. What follows is still my laptop batteries, for example (models of laptop is Fujitsu’s FMV-575NU / Y), introduced the replacement battery cell.

Although laptop batteries at the same time, there are two sets of batteries to power the machine, but with the test film multimeter Store Laptop batteries touching the spring, found the battery marked “+” or “-” the metal two springs in contact touch pads are interdependent, which means that the battery is actually two machines in parallel to food.

Battery with a blade along the slits on the sides of the battery carefully cut and found the battery box, a total of 16 monomers, which can be translated outside of a cell voltage and capacity, respectively: 1, 2 V, 1000mA. Although its shape and size and the general on the 5th, as the nickel cadmium batteries, but with the toshiba PA3465U-1BRS battery capacity on the market can not find. Finally, a store second-hand computer to find a Fujitsu FMV-575NS / batteries for laptops L, the label can be seen from the shell of the battery is Li-ion battery (Li-ion), tension 10.8V, capacity is 2400mA. And the battery on my laptop while Fujitsu, but the voltage, capacity and batteries are some differences in their nature, can replace the heart was not in the end, but still spent 180 yuan bought.

Home to the lithium battery open, rounding the circuit inside, remove the battery 6 monomer, a single cell parameters are: 3.6V, 1200 mA), according to the original arrangement of the circuit to the battery 22 in parallel and then series, using duct tape for six cells connected in a series of warehouses and under the battery of the laptop. Some laptop batteries in both positions with the “+” connected to a spring to choose the film touches arbitrary use with the battery cable connected to the positive terminal, so choose one with the “-” connected to the touch compressed spring and the battery connected to the anode. Finally, we need the original laptop batteries due to both labeled “T” word for the metal interface of an electronic component (this component is estimated laptop in the identification circuit of the battery to detect whether battery connected to the notebook) were removed, the welding position corresponding to the touch laptop spring on chip (if not this component, use the apple iBook G4 14 inch battery to the laptop power supply, the Power On Self Test appears after a while, the machine automatically shut off phenomenon). Of course, these operations must be conducted in the shutdown state.

As for the use of force after the reform, we should say is rather satisfactory: I just bought a laptop battery works more than 50 minutes, and disposal after use change of such methods, we found that the batteries of laptop computers can escape through the 2 hours continuous operation experimental 40 minutes, I was very surprised. Although this example is in my laptop Fujitsu’s experience from the successful experience of the current situation, but we can understand by analogy. It should be noted that the restructuring should take into account several key factors are: Battery voltage, nominal capacity and volume. A little different voltage and rated capacity, not a big problem, but if the TravelMate 290 battery after the reform are too large will not fit into the warehouse of the original battery, no matter how long laptop battery are not really meaningful (and you still can not laptop batteries outside, pulling a long wire with Jigen bar – if so, the portability of laptops is significantly reduced in!)

Ultimately remains to remind you that this method has great risks, for reference, there is no certainty do not apply. Otherwise, in the process of restructuring and unexpectedly, and my education “Chinese computer” are not responsible.

Editor’s Note: This article is mentioned in several respects, indeed, applied to a number of occasions, such as maintenance of mobile phone battery. In addition, the movements of exchange battery, as this author can buy the same second-brand laptop battery hand and get used the example of lithium batteries can be described as lucky. Lithium batteries performance is good, but can not make this event, readers can use in practice, instead of nickel-hydride batteries in metal. Currently, there are many sales in the electronics market nickel-hydride batteries, metal, we can buy as needed. Add that use nickel-hydride batteries in metal have several advantages: first, cheap, easy to access; Secondly, the nickel-metal hydride batteries are not “smart” lithium have not need more of the auxiliary circuit and turn it more convenient Completed batteries for laptop computer use in place a more secure world: the three, only the voltage nickel-metal hydride batteries to 1.2V, 3.6 cons V Li-Ion batteries need to be more easily combined into a voltage. Of course, gaps nickel-hydride batteries in metal are also very obvious, the weight of the component, a relatively low capacity of Dell U4873 battery the main problem.
