June 25 evening, the ministry of populace alphabetic character announced afresh automotive vehicle constructing accompanies of Department of Energy and conventions from access direction intersections, and comprised effectual along July 1. Industry psychoanalysts appraisal that the convention first the grandness by nickel-hydride batteries, metal beyond lithium batteries, a lot of towards the later evolution of Communist China Modern DOE vehicles.
According to an functionary alphabetic character about the prescribed site from the Ministry of Communications, the fresh energy fomites, admitting hybrid electric automobile vehicles, consummate electric car vehicles, electric car vehicles to fuel cell, hydrogen vehicles, centrifugal d ' early energy beginnings (such storage devices, superior, dimethyl aether) self-propelled and extra cartesian product categories. Centre is in the main on the new Department of Energy self-propelled three circumstances: compliance with safety, environmental security, push saving, condom and extra standards by authorised letter of the alphabet Department of the denominated testing organization proved and don't contravene the intellectual belongings rights of others.
The rule testament cost afresh DOE automobiles comprised divided into early on leg, once the period of developing, brings about of due date of 3 different technologies. Fomite fire cellphone, hydrogen elevator car and the car engine dimethylether initial stage, lithium-ion Laptop battery high-powered hybrid cars, commercial vehicles and complete electrical vehicles dwelt to the period of growing; nickel-metal hydride batteries, lead battery-acid barrage production from hybrid cars, complete electric car vehicles, pure electric and electronics are completely mature commercial product.
Depth psychology of the investment advisor car Sheng-mao said: "Surprisingly, ahead the industry's brightest BYD dual-mode electrical vehicle, dwelling to Li-battery car ion in the accession rules are classified as mathematical product* inwards exploitation, the future While we mass, only only to the blessing of the regional apply in marketing.”
He likewise noted that "governs embodied introduced, commemorating the Energy Department manufacture new to car fashionable the acceleration form, the intersection structure is corrected. The various intersections of new get-up-and-go vehicles will case another future. As nickel-hydride barrages, metal companionships’ automobiles are an crucial right. "
When enquired why such that a change comes about, he explained: "The reason wherefore the body politic is at present central to the development of lithium Ni-hydride batteries, metal, the main reason is that the nickel - hydride technology of metals of the Dell Inspiron E1505 battery is more matured than lithium batteries, mineral resourcefulnesses more fitly in future come through lighter for new Energy Department vehicles in the commercialization degree. is now the chairing supplier of nickel-hydride batteries in metal are far Keli
Li Sheng-mao, according to the interpretation of the decree is additional significant import costs that for the country after the introduction of consumer subsidies because Modern energy fomites, also because 10 metropolises pre-1000 model work to litter in the future the various auto companies will constitute supported the standard applications programme, report their new get-up-and-go frameworks.
From June 26, the day the commercialise reaction, the banal car doesn't happen fortify. "Now, everyone has the new energy vehicles, the rules birth little impact on-duty the grocery store, but industriousness has a normative part, first on that point are hp PB991A battery standards to enter the path of industrial development.”Pacific Securities Research Institute researcher to discuss inter-vehicle to consider.

(0) A1012, VGP-BPS2, F2024A, Dell FK890, Laptop battery
Often see friends asking to buy lithium batteries are to see how much voltage (V), or the number of discharge (C)?
Regarding the voltage and discharge capacity (which can be understood as the discharge capacity of the Laptop battery, the more C's highest output current of the battery), there is too much battery capacity I will not explain. I can only talk about how in the end kind of battery to buy the most profitable.
A lithium battery generally three indicators:
1. Voltage, in general, we use the most is 11.1V, of course, there are 7.4 V, but few people use.
2. Who is the subject of both battery HA (mA), we often 1500MHA, 1800MHA, 2000MHA etc.
3. Discharge parameters is the battery on the number of C, C indicates that the number of the larger piece of the Dell FK890 battery can perform most of the current. In fact, C is the number of battery current, an expression such as a battery 2000MHA 10C, then the current maximum is 2000x10 = 20000 mA, which is 20A. If 2000MHA 20C battery, it is then the maximum discharge current is 2000X20 = 40000 mA, which is 40A.
If we compare to a bucket of the battery and the voltage (V) can be interpreted as a bucket placed on the height, if the bucket to the higher, the power of water erosion, while the ability to on behalf of the bucket may be how to load the water, of course, the higher the capacity of the packed, then use the most, all that well understood. Discharge is the root of this network, it picks up more crude oil to turn the water pipe, water pipes coarser (C slightly larger) on the release of water at the same time, more time and more in the unit can power the most.
To see some friends here, says he will think so, and you said for a long time is that the more the better buy these indicators well.
Oh, is not everything. Standard Lithium-Ion hp F2024A battery is now empty of serious side, even if you purchased a large number of outside power lithium-C, it is certainly good?
Generally speaking, the more C, plus the battery capacity of more expensive, higher capacity battery, the higher the volume, sometimes affect our use, for example does not fit into the M4, G36, MP5 care Muli these dogs, if you want to increase the battery discharge current can improve the parameters of discharge (C) l '. But the example you buy a piece of 11.1V 4000MHA 30C Lithium is not the rate of fire can do better than 11.1V 2000MHA 15C load faster? Not necessarily! Because the battery does not gear driven gear-driven engine is! While the motor voltage and current have a certain limit, so it is easy to burn the engines too, the original engine and high-speed motors in the same dogs, with a performance of the sony VGP-BPS2 battery case is completely different is the original engine at high speed and engine power, it is different, high-power engine speed much higher than the original engine, so the high-speed motor replaced after the battery faster and easier to heat reasons. Therefore, for a high-speed motors need replaced after a high-performance batteries, to ensure that the use of more time.
Original car is not normally need to buy more than the current production of over 20A battery, it will be very easy to burn motor, while the high-speed motors will have to motor performance, according to buy batteries on the one hand, play the largest engine performance, but not the motor burn out. In general, high-coil motor speed motors, high torque and the engine must be original hard, they are able to withstand higher current, this time the number of C may be larger, high-Twist Motor Coils slightly smaller, so C is preferable not be too many.
Currently, several friends have purchased a high torque motor, the firing rate is not high, we use high-current battery to red, then in May believe the rate will rise, but after all belongs to over clocking, use a long period will certainly be damaged engine. Therefore, when the main battery to buy depends on your engine's performance and quality. In order not to receive the battery power is too small engines do not play the best performance or power output of the apple A1012 battery is too high and burnt the motor tragedy.

Experts say the future of hydrogen fuel battery is energy storage power station
hp PB992A, VGP-BPS2B, Dell Inspiron 5150, Laptop battery
Hydrogen as energy carrier for fuel battery has been the development of new energy vehicles. Recently, however, Automotive Engineering, Tsinghua University and Development Research Institute, Mr. Song Jian, Vice-President stressed that the high cost of vehicle fuel Laptop battery, hydrogen is difficult, the technology of fuel batteries for development of new energy vehicles does not seem practical.
The high cost of vehicles to hydrogen fuel battery is difficult
Vehicle fuel battery operating principle is: always sent by the fuel battery hydrogen fuel and oxygen under the influence of the catalyst in water while producing electricity driven generator to drive the wheels turning. Although this new energy vehicles emit virtually zero, but due Song, costs are high, restricting future development of hydrogen is difficult. "Fuel Dell Inspiron 5150 batteryin the car can not replace anything, just a device for converting energy, is equivalent to the rising cost of cars." Song said: "The current generation technology of fuel batteries, the price per kilowatt-General to $ 20,000
In addition to manufacturing costs are high, the hydrogen is also difficult for low-cost access to one of the problems encountered. Song said: "At this hydrogen by electrolysis of water: the acquisition, use a high cost. Because it is gas, there is a huge and difficult, it is difficult to store and transport. And even in the small spark of static electricity can easily ignite under, there are a security risk. "optimal use:
The most appropriate storage of solar wind
The technology of fuel VGP-BPS2B batteries for the development of new energy vehicles does not seem practical. But Song made, using similar techniques to construct the station energy storage power, stabilize the voltage, frequency, regulate peak electricity and the valley, but it added a good choice. "Wind energy, solar energy by the excellent weather conditions and volatile output, if they are directly integrated into the grid, would damage the quality of food." He explained, "it would better as a fuel conversion device batteries, wind energy, energy issues Solar Electric in situ electrolysis of water into hydrogen and oxygen, then through the fuel battery to generate the electricity. it would lead to the voltage stability of power, frequency stability, and better suited to enter the gate. when hydrogen becomes a storage medium for energy. "
Song also said that, initially designed for generators to power fuel hp PB992A battery car, has the characteristics of fast start, can not simply be used to adjust peak and valley. Consumption in the trough, to ensure energy efficiency, excess capacity may be the first store. Wait until rush hour, just 12 seconds of time, fuel batteries can bring electricity to be released.
However, given the current high cost of fuel batteries and abroad have not used it as an attempt of energy storage power plants.

A New Material Makes Lithium-ion Batteries Safer
A new material developed by researchers aims to put an end to fires and explosions caused by the lithium-ion batteries commonly found in phones and other mobile devices.
Lithium-ion technology is used in batteries for most electronic devices today, from iPods and the iPhones to laptops, digital cameras and more. The technology has been considered safe for years, but damage and production defects have led to high profile fires and small explosions. A few years ago, several laptop battery fires prompted Sony to spend hundreds of millions of dollars on a massive lithium-ion battery recall.
This same battery technology is now being used in hybrid vehicles and electric cars.
To make lithium-ion batteries safer, Taiwan's publicly funded Industrial Technology Research Institute (ITRI) developed a new polymer, STOBA (self-terminated oligomers with hyper-branched architecture) to keep them from overheating. The polymer is added to the cathode material inside a lithium-ion IBM ThinkPad R52 battery.
"Fires or explosions in these batteries are caused by short circuits," said Wu Hung-chun, a researcher at ITRI, explaining that even minor mishandling such as dropping the handset could result in damage causing a short circuit.
The answer was to develop STOBA, which suppresses thermal heat in case of a puncture or other severe damage. Wu showed a video of tests of a common nail puncturing a mobile phone battery, which caused it to heat up to over 650 degrees and explode. A second test on a mobile phone battery with STOBA technology saw the heat reach only 140 degrees. The researcher warned that people should not try such experiments at home.
ITRI is currently working on a production process for STOBA, Wu said, adding that the technology will only add about 2 or 3 percent to the overall cost of a lithium-ion Dell GD761 battery.
"The technology is ready for lithium-ion batteries used in electronic devices, mobile phones, laptops, no problem," he said. ITRI has already started testing STOBA on electric car batteries.
The Taiwanese research group isn't the first to develop safety technology for lithium-ion batteries. Sony, Toshiba and other lithium-ion battery makers have been working to improve the batteries for years. Three years ago, Panasonic announced a heat-resistive insulating layer inside its battery cells meant to keep the batteries from overheating in the event of a short circuit.
ITRI also on Thursday announced an agreement to work with E-One Moli Energy to explore ways to make lithium-ion batteries for hybrid cars and electric cars safer and more efficient.
The five-year deal was made in part to take advantage of government incentives to promote alternative energy projects and to take advantage of new technology for lithium-ion batteries.
E-One makes batteries for BMW's Mini E, an experimental electric car that uses lithium-ion batteries.
E-One's latest electric car battery prototype, the eTaxi BEV, costs US$100,000 currently, gives a car a range of 120-150 miles (190-240-kilometers) before needing a recharge, charges in two to five hours and accelerates from 0 to 60 miles per hour in 7 seconds. The battery contains 5,000 cells, compared to the 3 to 8 cells found in common laptop batteries.

Apple laptop battery use method
Apple battery, laptop, battery
Just a quick note you can maximize the use of battery life Apple's Notebook (which must be recharged before use of the time), and battery life. One of the most important points is that in the temperature range appropriate to use your Apple laptop battery, (please refer "Notebook PC temperature). Do not be trapped in the heat of summer on closed areas.
Your new laptop
When you bought the laptop using the new computer, consider full power, then run Software Update to ensure that your computer is equipped with the latest software. Apple will release updates of software on a regular basis to improve battery performance.
Standard maintenance
For the lithium battery to maintain it is very important is to make the battery in the electronic version continues to flow from the state. Apple recommends that you should not use a portable power. Ideally, the use of the method will use your laptop batteries Apple back in the office using the power supply for recharging. This can maintain the flow of liquid from the battery. On the other hand, if you use the desktop in the enterprise, but only when they emerge from time to time using a laptop computer, Apple recommends charging the battery at least the time of discharge per month. Need not be reminded? ICal calendar on your desktop that you can add an event reminder.
In the long term storage
If your laptop is left idle for more than six months, Apple recommends that you remove the battery, and maintained at 50% of the power state. If the store where the power is equal to zero, the battery will be due to excessive discharge can not afford any charge. On the contrary, if the store when the battery is fully charged, will be some loss of battery capacity, is to shorten battery life. Please remove the A1045 battery after storage at proper temperatures. (Apple notebook computer running at optimal temperature of 50 ° to 95 °. You must be stored in an environment of -13 ° to 113 °. In other words, 10 ° to 35 ° and -25 ° to 45 ° is running and the proper temperature for storing laptops. Try to get close to Apple at room temperature (22 ° C) is the best.)
Best Set
You can choose how to use notebook Apple to maximize battery life.
Energy: Energy Saver control panel offers several settings options for you to control energy use Apple laptop. While booting, the computer would be to flee. In the control setting of state power, the computer itself, as the screen brightness dimmed, and limited use of other features. If you change this setting to maximum performance, capacity will be exhausted more quickly.
Brightness: The brightness of the screen transferred to the comfort of the lower end, the battery can maximize use of time. For example, when watching DVDs on the plane, if all the surrounding lights off, you do not need the higher brightness of the screen.
AirPort wireless network: Even if you do not use features AirPort network, it will consume. Therefore, to save energy, you can disable it in Control Panel.
Bluetooth wireless connections: Also, do not use the Bluetooth function in the case of electricity will be consumed, so you can also use this function without having to disable it in order to prolong battery life.
Applications and external devices: Please disconnect temporarily out of use of equipment and unused external applications. CDs and DVDs should not when you're out of the CD-ROM drive.

Liquid-lithium-ion (Li-ion) as a vector of energy efficient has been widely used in communications, electronics industry, particularly mobile phones, PDAs and other personal communication tools. But in the last two years with the rapid development of communication technology, mobile phone technology color screen, multimedia technology, Bluetooth and cameras continued emergence of the battery capacity, size, weight and electrochemical performance indicators such as rising demands, the traditional liquid lithium has become increasingly unable to meet the new requirements. The emergence of new type of polymer lithium-ion battery (Li-Poly) supply that need. Polymer lithium-ion battery is the original steel, the aluminum battery developed on the basis of the third generation lithium-ion battery, with its lighter, thinner, characteristics of higher energy density by manufacturers of communications terminal domestic and international design companies to benefit. Polymer Lithium-ion batteries with liquid lithium-ion batteries the most fundamental difference is that the two different electrolytes used. The external view of Rechargeable lithium polymer electrolyte is solid state, known as solid polymer electrolyte. It is a kind of electrolyte in solid, but it can dissolve the liquid as the supporting electrolyte and the phenomenon of migration of ions can produce polymeric materials.
The following examples of the use of the eight major advantage of lithium polymer for the reference peer.
AKE 12V / 1300mAh samples of lithium polymer engineering, installation of automatic protection panels can short circuit, over charge, over discharge protection effective. And the VGP-BPS2B battery can be charged using the charger reliable shares, without having to worry about overcharging or charge does not eat into the atmosphere. Monomer voltage lithium-polymer is typically 3.7V, the maximum voltage of 4.2V.
1. Good safety performance
Lithium polymer on the use of flexible plastic packaging in the structure is different from piles of molten metal in case of potential safety problems, liquid batteries are explosive, while polymer batteries do drums.
2. The thickness is small, can do even thinner
Shell first custom ordinary liquid lithium PLC after the Serbian village of positive and negative ways to get the desired thickness of 3.6mm following, there are bottlenecks in technology, polymer laptop batteries, this problem did not exist, the thickness of 1 mm can be achieved below the threshold today with mobile phones guiding demand.
3. Weight
POLYMER BATTERIES lighter than steel of equal capacity lithium-standard 40 percent lighter than light aluminum battery 20%.
4. Large capacity
Polymer battery types of steel from the battery capacity even 10 ~ 15% higher than the battery aluminum 5 to 10%, a color of choice for mobile phones and multimedia mobile phones now available in a new color screen and MMS cellular phones were used primarily polymer batteries.
5. Resistance of small
POLYMER BATTERIES internal resistance of wet cell batteries is usually low, the current resistance domestically produced polymer batteries can even be below 35mΩ, which greatly reduces the car's battery consumption to extend timeout phone can be achieved with the international level. This important support discharge lithium-polymer course is ideal for remote-controlled models as the most promising alternative products for Ni-MH battery.
6. Form can be customized
Polymer battery based on customer needs to increase or decrease the thickness of cells, development of new cell type, inexpensive, the open mold cycle is short, and some can even be adapted to the shape mobile phone to enjoy the space battery shell, enhancing the capacity of the LCBTP03003 battery.
7. Excellent discharge characteristics
Batteries polymer electrolyte gel compared to liquid electrolyte, gel electrolyte of a stable discharge characteristics and improved shelf discharge.
8. Protection of the card design is simple and
Because polymer materials, batteries did not fire, not explode, the batteries themselves have sufficient security, so polymer battery protection circuit design may be deemed omitted and the PTC fuse, saving the cost of the battery.
Lithium-polymer safety, size, weight, capacity, performance discharge, both have great benefits, but the current production capacity, due to manufacturing costs are high, so high prices, the price has become Impact Universal Battery lithium-polymer bottleneck.
