Millet is often the wonder: If he can not quite understand what the discharge of certain measures. The possibility has completely expired, how do? Loaded until the Laptop battery is in the automatic shutdown, or how much to keep? 

And as pointed out some familiarity Search

If you now have the same problem, such as millet can refer to a look

 

Should first understand a little on the battery

 

Secondary Batteries Battery.

 

Re-use after discharge batteries, including nickel-metal hydride batteries, nickel-cadmium batteries and lithium batteries. The amount of the charge-discharge cycles, mainly due to the reversibility of the electrodes, membranes and structural materials in the charge-discharge cycle stability. The most important use of rechargeable batteries for mobile phones, laptops, digital cameras, portable DVD and so on, the main producing countries to Japan.

  

Lithium Batteries

 

To isolate the second Dell Inspiron 700m battery (ie rechargeable) lithium batteries Art lithium aluminum oxide cathode, liquid organic electrolyte and anode materials made of carbon, but also separates between the positive and negative electrodes on the diaphragm, the positive and negative, to prevent short circuits, while the liquid organic electrolyte is contained in a multi-porous plastic insulation membrane is responsible for the work of the ionic charge conduction.

 

Lithium battery with energy density, operating voltage of the high temperature range, no memory effect, long life, etc., but the higher price.

 

The latest digital cameras with lithium batteries, there is no memory effect, open the flash and color LCD display faster than the use of nickel-metal hydride batteries to be efficient. But the mobile phone market, especially nickel-hydrogen batteries have memory effect, more power than the standard nickel-cadmium batteries, a long and load faster. Memory effect in nickel-cadmium VGP-BPS9 batteries are the heaviest.

  

Memory effect

 

If each charge in the negative electrode, the role of cadmium and have produce hydroxide to metallic cadmium in the negative electrode deposited surface discharge, the negative electrode surface of the metal cadmium in response to the formation of cadmium hydroxide, which is broken – the deposit reaction when the charge incomplete discharge, the electrodes inside the cadmium metal slowly produces large crystals Er Shi hampered by the chemical reaction, leading to capacity to reduce the performance of the material, namely the so-called memory effect. Early use of nickel-cadmium batteries, this effect is most evident.

 

Nickel-cadmium batteries, because of strong memory effect, it is easy to load and unload because of poor, which leads to less available capacity, should facilitate the use of 10-that is to do a full charge and discharge when it memory effect, then three times in succession can do on the five complete charge and discharge cycles to release the memory. Ni-MH battery memory effect due to the weak (can be said that almost none), so about 50 times when we used to do in order to complete loading and unloading.

 

The next step is to deal with a lot 

 

To start in the following cases, the battery for processing:

1. Has recently opened a new battery.

2. For a long time the battery not the battery from your computer using a storage situation is now being re-enable this battery.

3. A long time do not use the battery from the notebook or laptop stand of memory (more than two or three months) and are now re-enable the battery.

 

The battery to start treatment methods:

Start the chemicals in the battery to maximize hp F4812A battery performance, by repeatedly charging and discharging of the battery (fully charged and then fully discharged) three times. The so-called complete charge and discharge cycles: the normal boot, so that the battery consumption to 3% of battery power (preferably once exhausted, can be divided into several times to come to power, but not too long) break, and it must immediately shut down the battery twelve hours.

 

Here, stressed the need to immediately charge the battery because the battery will be carried out without the use of self-discharge when the battery to 3% of the electricity in that time if the battery can time the phenomenon of self-discharge of the battery easily lead to over-discharge costs of the battery discharge on lithium batteries is a big taboo.

 

Start the battery charging process, the machine must be switched to. If the machine at this point to wait until the conclusion of the State may, if the load is up to 3 ~ 4 hours after the green power status indicator lights no longer beat, the machine will automatically stop charging the apple A1022 battery, so the battery is not fully loaded. If the discharge to 3% of electricity, the machine will automatically go into sleep mode immediately should this time be rebooted the machine, the machine starts the process, click Stop button on the bottom left of the screen, so that the machine is shut down.

 

If this operation had a good view of every detail, and the quality of your battery is not a problem, we may very well start the battery of chemical substances in order to maximize the performance of the battery, is basically a normal battery after each use of the be able to charge to 100%.

Battery pollution affects human health

Posted by admin on November 20, 2009
Digital battery / No Comments

We must eliminate the gasoline cars pollute the environment and the development of new energy vehicles, but used in the production process and recycling of batteries of pollution on human health, it is worth?

 

Fuel cells, hybrids, pure electric, three sets of new energy vehicles, and more hybrid cars must use oil, the rest has no oil.

  

The first with hydrogen, the latter with the power, it is known as green products (hybrids can reduce exhaust emissions).

 

It is expected that the loading of the Laptop battery power of hydro, wind, sunlight, power nuclear energy, thermal energy is also the valley of the night to use their power. This green energy sources and renewable electricity, of course. Hydrogen production from renewable electricity. Of course, hope that one day these ideas can become reality. Three sets of cars need to use the storage battery power or auxiliary drive vehicles, or vehicle main engine. The battery industry is currently the main strategy of the lithium battery. In the hybrid with the original nickel-metal hydride battery-based, pure electric vehicles using lead-acid battery Uehara.

 

Now the industry for several batteries or controversial, which one is better than both merits and demerits. Li-ion battery as the energy that can quickly download large load can quickly adapt to a wide range of temperature. In recent years, a greater increase in performance, the cost has decreased considerably, people placed great hopes. However, a relatively large number of constraints, is a technology development, research and development that require research.

 

Lithium resources of the world’s 15 million tones, China about 390 million tones, about 28% of world total, ranking second in the world. It is estimated that 1 g lithium metal Dell Inspiron 700m battery can be about 0.6 ~ 0.8Wh (and the synthesis of cathode materials related to materials and synthetic related to the negative performance of the electrolyte and synthetic).

 

For a compact car, for example, electricity consumption per 100 km of pipe approximately 15 units of electricity, online renewal mileage of about 150 km, the lithium storage capacity in the 30kW / h ~ 35kW / h, the group of lithium batteries lithium metal contained in 50 kg above, equivalent to about a mobile phone battery (rechargeable batteries 3.5Wh) 10,000 times. 121 Beijing Road, a model of pure electric passenger large, its total storage capacity of the lithium battery is said to 160kW / h, the total weight of about 2 tons, the lithium metal content is approximately 280 kg or more.

 

Toyota Prius hybrid is the use of nickel-hydride batteries in metal, but the storage capacity is not. Small reserves of nickel is used in electroplating, coins, stainless steel must be important. Lead-acid batteries oldest and most mature, maintenance free type has been widely used in many ways two-wheeled electric vehicle, costs may also be 3C-load current and the discharge can be of 2 hours and the rate of discharge current. Lead is rich in resources, huge production of China, representing about 40% of the total world. However, the refined lead metal, lead plate manufacturing, assembly of hp Pavilion dv2000 battery and recycling of waste batteries and regeneration of various links workers to harmful pollution of the environment. The consequences are increasingly shows that after a century of lead acid batteries, tough, with its space needs for energy storage is mainly used in soil, a large number of vehicles used must be controlled .

 

Lithium, nickel limited resources, need to use up too much power to the car battery is a disposable, not a path towards sustainable development. With lithium, nickel resources, the substitution of the limited resources of oil, it is not wise. Pollution, lead acid batteries can not be avoided, can the less the better. To replace the pollution it generated emissions of greenhouse gas emissions in the internal combustion engine, an exercise is a tiger wolf.

 

If we actually use lithium, nickel-metal batteries that traction and equipment in vehicles with new energy, and is also the industrialization of new energy vehicles, but also exported, so that enough resources for few years? Should not be used for other purposes? (Bus one group of lithium to 2 tons, while the lithium metal is about 280kg. Ni-MH VGP-BPS2C battery of about 4 tons and nickel how much, no one has published data).

 

If we use equipment of the lead acid battery, electric cars, electric buses, and the year may change a battery, then the large amount of surprise. Beijing City Bus has lead acid batteries, weighing about 6 tons, a compact car needs a hundred kilograms (maintenance free lead-acid battery-based storage capacity of its 35 – 40Wh / kg, while riding a bus if 60 people, the number of quality of care, certainly not 6 tonnes. It is 6 tons of batteries installed in the slope of the vehicle forward every day to and since the technique probably unreasonable, undesirable.

 

We develop new fuel-efficient vehicles (electric), replacing the oil on a tight end in itself, but to consume less resources, lithium, nickel-metal that science? Viable? We must eliminate the gasoline cars pollute the environment and the development of new energy vehicles, but used in the production process and recycling of batteries of pollution on human health, it is worth?

 

Energy vehicles Consequently, at present, new, if you want to use this storage device and energy storage means, it is necessary to explore his identity. Currently at prototype stage demonstration turned too late. “DDT” jokes will not be repeated here.

Hybrid electric vehicle is the best transition of goods, battery technology affect the development

Pure electric vehicles and vehicle fuel Laptop battery in the car using the process to achieve zero emissions, and can completely get rid of dependence on oil resources, development of new energy vehicles will be the ultimate goal, and choice the route of transition, due to cars alternative energy and health energy vehicles more dependent on physical energy associated with the development of regional characteristics, it is difficult in the global promotion, hybrid vehicles because improvement of the current automotive technology is relatively small, in the period of high oil prices have a better fuel economy and meet the emission standards high, the transition is the best way.

 

Companies in the Japanese automotive industry to seize the lead

 

Hybrid cars work, you can use two types of mode of mechanical and electrical drive, for example, a plug-in hybrid technology makes the process more convenient pricing is the tendency of development of hybrid cars.

 

From the worldwide sales of hybrid electric vehicle distribution point of view, the United States is the largest sales of hybrid electric vehicle market in 2007, sales of 35 million units, representing 70% of sales Global, Japan, Britain and Canada, IBM ThinkPad R40 battery market shares, respectively 13.8%, 3.2% and 3%, while other countries, only 10% of the total share of the market to be developed more.

 

In the hybrid car in the United States, the largest consumer data, the Japanese auto companies, with its field of hybrid cars first advantage engine, has occupied the market. Market for hybrid cars from Toyota stood out, its 2007 revenues to U.S. $ 18 million, occupying 79% market share, Honda, Ford, GM and Nissan’s share of 10.2%, respectively, 7.1%, 1.5% and 2.4%.

 

Global sales reached one million of best-selling Toyota Prius in 2006, landing in China after the sale had been poor in sales volume in 2008 should remain Dell Inspiron 700m battery in the 1000 shows that the average current consumption of China Vehicle hybrid does not endorse the purchase of desire is low, the Chinese market will be developed.

 

Cost advantages of high-priced car

 

Compared with conventional cars, hybrid cars use the cost advantage is a prerequisite for development. Under current conditions, the use of hybrid cars benefit costs reflect the price of $ 20 or more cars, hybrid technology in the price of 5 million cars do not use cost advantages, even if we could reach 100% of the fuel economy effects, the use of cost – is still 22% higher than conventional vehicles, in the price of 100,000 yuan and 15 million motor vehicles, only 80% or more of the effect of fuel economy, only a small hp OmniBook XE3 battery cost advantage, in the price of 20 million yuan, 250,000 yuan and 30 million vehicles to achieve 40% -60% of fuel economy effects reflecting the use of certain cost advantages, indicating that hybrid technology has real value.

 

In essence, the cost advantages of hybrid vehicles is the cost of electricity compared to the cost of the benefit of oil. 93 # If the price of petrol has dropped 30 percent, or 4.46 yuan per liter, while the use of hybrid technology, cost advantage will be smaller, the sony VGP-BPS5 battery actual value, if 93 # Price Gasoline rose 30 percent, or 8.28 yuan per liter, then the mixture power technology will be most obvious practical value.

 

Technological progress is the development of hybrid cars, a powerful, if technological advances and determine the price of electricity decreased by 30%, its hybrid technology to enhance the role of cost-competitive with gasoline prices increasing 30 per cent have a significant impact.

 

Optimistic circumstances, the application of hybrid toshiba PA3399U-2BRS battery technology has broad prospects. 93 # If the price of gasoline rose 30% and 30% decrease electric drives simultaneously, then the application of the value of hybrid technology is very obvious price of 10 million yuan for the use of car have some cost advantages.

 

About the development of battery technology

 

The current hybrid cars use nickel-hydride technology battery metals major, but the nickel-metal hydride batteries have a number of technical performances, close to the theoretical limit, such as energy density, charge and the rate of firing. The lithium apple PowerBook G4 15 inch battery has an energy density, high capacity, no memory, etc., are car manufacturers and battery suppliers unanimous approval of the need to solve the problem today lies in its use of stability, security and cost of production.

 

Lithium iron phosphate is a lithium battery and high safety, high stability, high specific capacity, protection of the environment and the benefits of cheap, but its poor conductivity, is the need to address major problems. BYD Auto’s dual core technology of the vehicle mode is “AND-Power”, the use of technology in the lithium iron phosphate is, each battery voltage 3.3 V, 60 Ah, up to 2000 times the number of charge cycles and, especially, Zambia Di F6DM vehicle for living to 100 of the TravelMate 290 battery up to 430 km distance, 100 km in electric mode, the hybrid model of 330 kilometers, but actual production is still some time.

 

Compared was applied to the hybrid plug-in hybrid technology allows hybrid vehicles with better performance and ease of use. General Motors designed the Chevrolet Volt is to use technology lithium, PHEV, should be available in 2009, while the Toyota Prius is not due to technical problems the new technology of lithium used in cars. Volt lithium Dell HD438 battery on board is produced by the A123, the ability of 16kWh, the current Prius battery capacity 12 times, greatly improving the endurance capacity of hybrid vehicles, but “may be plug – in “design to allow for battery recharging more convenient, 110V under load of the interface can be filled with 6 hours.

 

In order to rapidly develop high performance, low power cost of the vehicle battery, the major automakers and battery manufacturers have adopted a cooperative approach to development, triggering a LCBTP03003 battery powering the vehicle for International Development in the world. General Motors moves in which the most active at the same time with the A123, Compact Power, Cobasys, and Saft four companies to cooperate, to seize the leading position in battery technology lithium, the intent is obvious.
