digital batteries

1, the pricing of common sense

Here, we must first note that the load is an important step in the use of rechargeable batteries. Load appropriate and reasonable to extend the battery life is very good, while the random brutal life of the rechargeable Laptop battery will be greatly affected. On one side, said the current lithium batteries are based on the basic package of each product individually and not jointly, if different products to provide their own equipment for loading, and not common, when in service as long as you can use to follow their instructions. While it is the introduction of the battery refers mainly nickel-cadmium batteries and nickel-hydride batteries in metal.

The battery compartment on nickel and nickel hydride batteries, metal, there are two ways in which we are known as “fast charge” and “trickle charge”. Quick charge and trickle charge is the charge of an important concept, and only learned about the fast charge and trickle charge in order to properly grasp the load.

Firstly, the fast charge and trickle charge is a relative concept. Some people have asked, my charger with charge current of 200mA is not load quickly? The answer is not absolute, should have answered some batteries is fast charging, and some batteries, it is simply loaded slow. So how can we judge fast charge or slow charge it?

For example, a 5, Ni-MH power capacity IBM ThinkPad T41 battery of 1200 mAh, while the other section is 1600mAh. We have a battery capacity is called 1B, 1C see is a logical concept, the same 1C, are not equal.

During loading, the load current is less than 0.1C, we called the trickle charge. As its name implies, refers to the current very low. In general, the burden of maintaining the battery can be comprehensive without harming the battery, but the trickle charge to use the time spent far too long, so rarely used alone, but rather, and other pricing methods used in combination.

0.1C, 0.2C charge current between the two, we called the trickle charge. Load current is greater than 0.2C is less than 0.8c is a fast charge. When the load current is greater than 0.8c, we call it super-fast loading.

Precisely because the concept of 1C is a logical rather than absolute values, therefore, according to 1C slow conversion of the fast charge is a charge of relative value. Mentioned in the previous example 200mA charging current for Dell Inspiron 1420 battery 1200mAh fills slowly, but it is for the 700mAH battery fast charge.

Aware of the concept of fast and slow filling, we also need to understand the situation charger can charge the battery properly. Charger on the market can be divided into two types of constant current charger and automatic battery charger

2, constant current charger

Constant current charger is the most common chargers, nickel-cadmium batteries of the time we started to use the charger with constant current. Constant current chargers typically use a load current slow, its use is relatively simple, just put the battery in the battery can be charged storage. Note that the calculation of the charging time must be accurate.

The calculation of the charge time has a simple formula: Hour = 1.5C / load current. For example: on the charger 1200mAH hp Pavilion ZE2000 battery charge current of 150mA, then the time to 1800mAH/150mA equal to 12 hours. Of course, in many cases can not be calculated exactly the time we can choose the nearest half an hour to facilitate the chronograph. For example: charger current 160mA, right 1400mAH battery charging, then time for 2100mAH/160mA about 13 hours, instead of calculating the points.

Construction of a simple constant current charger, labor stability, is a good way to charge little effect on battery life. But it also has its limitations, we must first calculate the time, while nickel-metal hydride batteries with a capacity for growth, the constancy of the time course load required for longer and longer, the use of ’cause a number of drawbacks. Thus, in recent years, rapid charger system is also very popular

3 autoloader and quick

Fast automatic charger in these two years are always better received, he has the speed of loading, security and so on. But there are also some people have doubts about this because of the fast chargers are essentially using current fast charge to charge, the impact of these people will be scared about the life of the sony VGP-BPS5 battery. So the current situation?

Firstly need to be sure that the current charging high impact on the life of the battery is very low, and in many cases, we use fast charge and even ultra-fast load, the current load can sometimes reach 2C or higher. Mainstream is not a killer battery, the real impact on battery life is the heat capacity at high current generated during charging.

We charge the battery when using the nominal voltage above the battery voltage to make, but the battery itself, the load current produces a back EMF, it is part of the current to compensate the the back-EMF and in vain for power and transformed into heat. When the load current is larger, more electrical energy is converted into heat, charging the higher temperature. Too high a temperature on rechargeable batteries is harmful, and a slow charger with constant current, because it is slow charging, the heat generated within the control box, so no need to take special measures. But in the ADF rapidly using a fast charge current will generate high temperatures. Therefore, currently available rapid charger automatically have adopted various methods to reduce the load when the temperature, typically using the cosine law is not a constant current load, but it has intensity current wave of cosines The changes that will reduce heat buildup, thus controlling the temperature within a certain range. Since this type of charger is no longer using the constant load current, charger current is constant in the past, a clear distinction between

To use the quick charger Another problem is that when the charging time is counted if you forget to stop after charging damage the toshiba PA3284U-1BRS battery charger to be much larger than the current slow constant overload resulting damage. Therefore, to solve the problem of overload, voltage fast charger is generally used as the France and other methods to determine the slope to determine if the battery is nearly full, these chargers are used to control the circuit, or IC chip to perform this task. When the battery is almost full, the control circuit will automatically slow charge mode, trickle charge the battery. Used trickle charge current of the battery on the advantages are obvious, the one mentioned above, can trickle charge the battery charge very complete, followed by anxiety billing question, if the maximum use of chargers such advantage n is not obliged to go computing time. The specific use to consult the manual for instructions specific to avoid improper operation.

It is a branch of the fast charger is ultra-fast charger, line battery charger applications of these small, design, structure and processes are very complex, so the prices are quite expensive.

On special occasions, people need in a time short of a good rechargeable apple M8403 battery, which requires the use of ultra-high speed charger. As the ultra-fast charger requires a lot of load current, and some have even used the 2C-3C load current, the heating problem is particularly serious, just by using the cosine wave accusation is not enough, both of these chargers adopted a cosine wave in the post – Insert a landfill very short this approach. This approach can reduce the back-EMF due to the consumption charge current generated by the accumulation of heat, so an additional control of temperature.

4, discharge

Were introduced to a memory effect of rechargeable batteries, we also know that when the memory effect gradually accumulated, would be the actual use of the battery capacity has dropped significantly. To reduce the memory effect caused by the negative role of an effective discharge. In general, nickel-cadmium batteries because of the memory effect most obvious, it is recommended to use 5-10 times after repeated charge for a discharge, while nickel-metal hydride memory effect of batteries must be better, you can charge made after the use of 20-30 times per discharge.

On the market a number of high-end loader to carry out their functions, but the vast majority of feeder medium and low Aspire 3000 battery is impossible to perform functions, then how can we do? To understand the principles of the landfill, we can also try to have the battery discharge.

We already know that nickel-cadmium batteries and nickel-metal hydride battery nominal voltage is 1.2V, but in fact, the battery voltage is a change of values, the adequacy of electricity around the volatility of 1.2 V or more. Generally fluctuated between 1V-1.4V, different brands of batteries vary in regularity, the fluctuation of voltage is not fully consistent with

Discharge the battery is to use a low current discharge, the battery voltage falls slowly to 0.9V-1V between the discharge should stop. Not recommended under the discharge of the battery of 0.9V, it will cause excessive discharge, the battery is not irreversible damage, said on a rechargeable battery is not suitable for use in appliances to the remote, because the use of the remote being very low for a long period of the remote is easy to use cause an excessive discharge. Following a performance of the VGP-BPS9A/B battery, you’ll be pleasantly surprised to find the battery capacity has recovered its original level, so when the battery capacity has been found to decline, it is preferable to a landfill.

His discharge the battery so there is easy way to make a small bead like electric charge, but you must use the meter to monitor voltage changes, to avoid excessive discharge.

For the shipper to choose the shipper to choose fast or slow charger with constant current, which depends mainly on the orientation of their own use. Such as the frequent use of digital cameras and other equipment from a friend, you should choose a quick charger, to meet time requirements, and even ultra-fast charger, you can buy, but only the use of portable devices listening as a friend, a constant current charger will be able to meet the needs of

In controlling the correct charge and knowledge of the landfill, everything will be better able to use their own rechargeable batteries. Please do not adhere rigidly to a fast charge.

2, focusing on the quality of the installation. The quality of installation, including storage, installation, capacity, and many other aspects of the experiment, so the transportation and storage must be careful not to collide during the installation process should pay attention tandem with the Dell Inspiron 1420 battery of the match between the battery carefully very unequal stakes race. In the extreme tightening of the stack, the force can neither too large nor too small. Will a bunch of very large forces in all loops of copper excess, too small, it follows from the convergence of poor contact with the fuel cell to install the best use of a convoy of supplied power was the key, or in accordance with manufacturers to provide a reference kilogram force, using the appropriate key kg. The facility should also be attentive to DC battery and the screen in each group between the battery positive and cathode, anode and cathode of the length of the line as much as possible to maintain the high discharge current battery, a balance between the two groups.

Must be put into service until the electricity surcharge. The installation of sealed batteries generally dates from the date of manufacture of a longer time, sealing the battery after long-term self-discharge, the significant loss of capacity must be based on a simple float hard to restore its ability origin. In addition, only difference in the size of the battery discharge, resulting in the proportion of the voltage across the battery so there is no balance, is not set service to complement the first, individual cells will be further expanded in the back of the hp PB992A battery or the phenomenon of anti-pole.

3, improving the quality of maintenance

The maintenance staff must fully understand the valve regulated lead acid batteries in the product specification of the requirements under the principle of engaging in maintenance work, improving the quality of maintenance.

⑴ temperature of the battery capacity discharge, life, self-discharge, greater shock resistance and other aspects, although the supply of power switching function with temperature compensation, but its sensitivity and magnitude, after all limited. Therefore, the hall of the battery must be installed in air conditioning and temperature control between 22 ℃ ~ 25 ℃. This not only extends battery life, but also has the best battery capacity.

⑵ once a month should be checked whether the charging device operating parameters under qualified, with or without alarm fault. In any case, the sony VGP-BPS2A battery float voltage must not exceed the manufacturer for a floating charge given, and by changes in temperature, at any time using the factor of voltage regulation of ± 3 mV / ℃ to adjust values of float voltage.

⑶ right valve view of the unbalanced nature of the impact of lead acid batteries must be used to float the lower limit for the floating voltage.

⑷ imbalance in the battery than the depth of discharge after the battery is running in one quarter, should be a balanced approach to supplement the battery. In the equalizing charge should pay attention to changes in environmental temperature and the temperature of the environment, but will decrease the value of balanced voltage settings. For example, if the temperature increases 1 ℃, then the equilibrium value of the charging voltage is necessary to reduce the 3mV.

⑸ try to use free pulse of the way “backwards battery” to charge the batteries to promote the activation and recovery.

⑹ careful maintenance, the valve regulated toshiba PA3191U-4BRS battery before going into production should be carefully recorded each voltage single cell and data on the internal resistance as raw data kept on file for six months for each subsequent performance is required to run the data compare with the original data, if the abnormal situation should be handled promptly.

⑺ must be measured once a month, the battery voltage and the voltage across monomer. Batteries sealed terminal measuring voltage can be in the floating state should be conducted in the state of discharge. Sealed battery voltage terminal to reflect the good working conditions 10 is an important parameter. Floating state, the measurement terminals of the battery voltage, due to the presence of the applied voltage, measure the voltage across the battery could easily lead to false. Although some anti-pole or open-circuit the battery can also measure the normal values (in fact, the applied voltage in the battery caused by the voltage difference at both ends), which is easily lost in the exchange sub electrical substations and power plants caused by the accident. Regularly discharge the voltage across the apple A1012 battery under the state measurement, this is completely avoided.

⑻ To ensure that the battery has sufficient capacity to conduct an annual test of the resilience (that is the great burden of Da-Fang), so that activation of the material inside activation of the battery to restore the battery capacity. The main method is to charge the battery from the machine into the battery pack controlled both ends of the load, while the current resurgence of the battery 0.1 times the rated capacity of each half-hour recording time voltage of the battery until the battery voltage to 1.8V / only (for 2V / only a single battery) or 10.8 V / only (for 12V / only a single battery) after the cessation of discharge, and save time. Put it aside, at 2am, then the same size of current on the battery to charge at constant current, the battery voltage up to 2.35V / only or 14.1V / just to keep the voltage on the load Battery 8am balance is a constant voltage of 2.25V voltage read / only or 13.5 V / only to perform a floating charge. The above method, you can make 80% of battery capacity due to the inclusion of the safe operation of the battery capacity can also be released for 30% to 50%, which should be verified and the discharge curve of the Aspire 3000 battery.

⑼ VRLA battery life is running in the 1 / 2, the need to appropriately increase the frequency of testing, particularly for single 12V battery to increase the test. If the battery internal resistance of a sudden increase in value or voltage instability measure (in particular, to two decimal places) should immediately as a “behind the battery” to carry out an activation treatment.

⑽ on a regular basis to check whether the onset of valve regulated lead acid batteries deformation and abnormal heat, carefully check the safety valves have been around the stain spray in order to determine if the valve Security tightened or damaged.

⑾ Battery capacity alone is not enough, because in need of replacement, only once replaced all, not just performance alone is not enough to replace the sony VGP-BPS5 battery down, otherwise they will be affected by imbalances in the internal resistance of batteries all the band playing drums and shorten the entire group of living cells.

⑿ not only the increase or decrease the number of single charge of battery cells, resulting in the ability of imbalance single battery charge and inconsistency, which reduces battery life. If the whole group as part of the stack to feed others, or the charge is not together with the discharge stack.

⒀ use of technical means to strengthen surveillance, such as the use of batteries on monitoring devices online, real-time monitoring of battery condition of employment. Pairs of substations unattended must also be sent to the central monitoring of information collected, the timely warning unusual processed quickly.

In short, we must attach importance to the maintenance of valve-regulated lead acid batteries, according to the different characteristics of valve regulated lead acid batteries, valve lead acid batteries, which affect a major factor in life and constantly improve the level of maintenance to achieve the goal of improving life in order to improve the sub-stations, power plants and the safe operation of the station level communication.

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.

Currently, internal research and development of electric vehicles are mainly used in lithium-ion batteries, but aside from battery production BYD, the majority of mileage endurance and speed are very limited, short duration, while security must be improved, currently, many failure rate of the Laptop battery is greater than one millionth of the level of security, burning vehicles and problems arise. These problems make electric cars the field of large-scale participation of private cars, there are many obstacles, which are common problems encountered in the world by other manufacturers.

Beijing Institute of Technology, an electric car expert said, a very important reason is that production of the 40Y6797 battery has not yet industrialized, there is a lot of batteries or a hand, small production, and therefore difficult to ensure the quality and unity. At the same time, users still have a lot of battery to use inappropriate need for more guidance.

Institute of Electrical Engineering Chinese Academy of Sciences, one expert said that the life of the current mileage is not enough battery electric cars at low speed using the scope is limited. At the same time, although some argue that the majority of electric vehicles can use the family 220V load voltage, but the actual operating point of view, usually filled with a Dell Latitude X1 battery lasts 10 hours or so, so long cooldown is neither convenient nor practical to use for this building Fast Chargers needed.

Charging station is difficult to achieve large-scale construction of

Improved facilities at the loading station of the electric vehicle is the key to the promotion scale. National Grid is currently pricing of infrastructure has accelerated the pace, Zhengzhou and Wuhan, a small number of charging stations and other places have been commissioned, but because of the high cost of station construction load, uniform standards for Jianzhan missing, investors are not clear and the relevant government departments to coordinate the hp F3172A battery large-scale construction makes the charging station in the short term is unrealistic.

“In fact, the current total capacity of electricity generation to meet domestic electricity demand electric vehicles, shortages of electricity does not exist, the key is that the feeding stations many The lack of capacity of storage, a large number of peaks and valleys are the loss of electricity. In addition, coal remains the major current sources of national electricity production, this sony VGP-BPS2 battery is not conducive to environmental protection, the State must increase investment in wind energy and nuclear power. “Beijing University of Technology, an electric car expert said.

In addition, construction of facilities so as to take charge of standards that must be resolved. China Lithium-standard system battery power ion drafting group of a person in charge, how to ensure that the construction of fast-charging toshiba PA3399U-2BRS battery charging station is key to ensuring the charging station can buses, taxis and private cars are able to apply, just as importantly, the technical level, there are some difficulties.

F3DM electricity as fuel costs ordinary vehicle 1 / 6

BYD dual-mode electric vehicles can be buttons F3DM in pure electric (EV) and hybrid (HEV) to switch between two modes. Holder of the battery life of iron in pure electric mode to achieve mileage of 100 kilometers with a total mileage of more than 600,000 miles lifetime of the vehicle to a maximum target of 10 years. Regarding power, BYD DM electric vehicle equipped with dual-mode power up 50kW / L power hair aluminum engine with 75kW, the apple A1061 battery power output reaches 125kW. In carrying load, BYD dual-mode electric vehicle can reach the office of professional equipment fast 10 minutes filled with 50% of the ordinary household socket can be used while charging, 7 hours can be fully charged.

Currently, the two official offers F3DM mode electric vehicles from 14.98 million yuan, according to a state of pure electric load, F3DM dual-mode electric car 100 kilometers of pure electric consumption is 16 degrees (data advertising works), according to Peking current 0.48 yuan / kWh electricity and travel 20,000 kilometers per year calculated at 1536 yuan per year for electricity.

Ordinary F3 1.6 Sheng automatic version of the official bid 798 million, more than double F3DM vehicle’s electrical yuan less than 70 miles. Its Aspire 3000 battery fuel consumption is about 8 liters per 100 kilometers, according to an annual mileage of 20,000 kilometers and the No. 93 Beijing oil 5.56 yuan per liter, to calculate the cost of fuel a year to 8896 yuan, F3DM for nearly six times the dual-mode vehicles. About the use of new and more than a year and a half, two-vehicle electric car can recover more than the cost.

Prius 8 years to recoup the cost of

FAW Toyota Prius production hybrid, using battery-powered engine, do not need to recharge. Its effective use in the process of around 100 km fuel consumption average of about 5 liters displacement of 1.5 liters, but with the HSTNN-LB31 battery, power output roughly equivalent to conventional gasoline 2.0 The dynamic performance model.

Under an annual mileage of 20,000 kilometers and Beijing, 97 to calculate the price of oil, the Prius oil per year for the sum of 5920 yuan, while the low standard with the Prius is currently the official target price is 259, 8 miles yuan.

Link to a substantial 2.0-liter model powered by a fuel consumption of 12 liters integrated by calculating hundreds of kilometers, the annual fee required for oil to 12,000 yuan, but the market is the 2.0L integrate models, with a unit for the Toyota Camry 200G Deluxe Edition (non-minimum distribution) price of only 209.8 thousand yuan.

In other words, the Prius 6080 yuan per year savings in fuel costs, but the car that the Camry is about the cost has increased by 5 million euros, which was part of the cost of an extra car in the car after more than eight years by the cost savings to recover the oil.

Lifan 320 electricity bill of about 1536 yuan per year

Lifan 320 electric vehicles (EV) is motor vehicle Lifan energy of a new prime.

Lifan 320 (EV) on a single charge life mileage will reach 150 miles high, the road conditions are also integrated over 100 km. 0-50 km / hour h in 6 seconds or less, even with a 100 km / h maximum speed drive 30 minutes later, the speed still at 75 km / hour or more.

The distance of the unit energy consumption was about 0.16 kWh per mile, according to Peking current 0.48 yuan / kWh of electricity and traveling 20,000 kilometers per year calculated at 1536 yuan per year for electricity .

Greater endurance Chery S18 150 km

Currently, Chery S18 electric vehicles has been out of the factory, but not yet recorded, according to published by manufacturers of parameters, its speed can reach 120 km / h, a rechargeable Dell GK479 battery life can reach 120 km Mileage -150 km.

Chery S18 vehicle electric vehicles in the S18 platform, developed on a high-speed pure electric cars may be used for 220V civil charge, charging time is typically 4-6 hours, and also be used for fast charging, a half-hour rechargeable battery 80%.

The battery of multi-buyers wondered why the battery of my old? After reading the contents of one would understand that we must understand why the capacity of the battery down? “The reasons for the decline in capacity, and why?” “The battery internal resistance will affect the capacity?” We then explain in details.

Laptop battery capacity after repeated loading secondary discharge will decline, its causes are complex and diverse, not only after repeated accusation, the discharge capacity will decrease, even long not to use, have the same problem of declining hardware capacity, rather than the charge and repeated the battery is discharged more easily damaged, because the battery is the use of chemicals from the chemical energy into electrical energy products, chemicals to maintain their regular activity and only less than a deterioration of failure, when the original activity of two compounds role of the end or nearly out of season, and will not be able to perform chemical reactions, this time the decrease battery capacity, that is, the cells are already gone, the battery must declare died.

Volume decline over time tends to happen when?

A good quality of the secondary battery, the continuous load and discharge over 500 times the capacity can reach over 70% even higher, but the decay rate of the IBM FRU 92P1141 battery capacity, plus good or bad depends on the battery cell, based on the battery yet to match the user the use, storage, temperature, remarkable degrees to prolong battery life.

Indeed, although marked as secondary batteries can be reused, but he still has his life there, so laptop battery, for example, the ability to label 4000MAH, but after the charge and discharge its capacity will be successively reduced by one year after the building are more likely to fall into the 3300mAh below, it is a normal phenomenon of secondary batteries, but can also see this problem is actually continues until that the battery technology, the use of both the meaning of love using a usually short period of time, and when using the battery Time is Running Free When this time to replace the battery.

What is a voltage difference?

Many Li-degradation capacity of ion Dell U4873 battery or failure due to a series within the battery due to voltage difference generated, resulting in cell battery produced the gap between tension can be avoided, because each battery string of battery cells nature can not be exactly the same, with a long time, there are some features of the natural and poor battery before aging, affecting the curve general discharge. It is with gratitude that the aging cell batteries have been the first full charge and discharge has also finished first place, but this time the ability of cells to the other battery is not fully utilized exhausted.

For example: load, others charge the battery kernel boot approaching saturation when the voltage is 4.2 V, while the aging of the battery cell may have been grateful to 4.3 V or a voltage even higher, causing an overload of electrical cords and other costs dissatisfied; discharge, when the strings are always large voltage range of work that is already grateful old battery or battery is already below the normal operating voltage , 3.0V, resulting in a unique string of low voltage protection, forming the hp PP2182D battery to discharge faster.

What is battery aging?

The aging self-styled drums, which, as the increased frequency of use and time, or long-term investment, leading to the capacity of the storage battery, the progressive deterioration, when battery is only one, the batteries, they will build the capacity reduction, while the group of battery Multi-core set-batteries in parallel, they generate all the associated voltage difference, this time the user is most likely aware, the battery is also clearly shown that over 50%, how suddenly dropped below 10%, and even non – normal shutdown, resulting from the use of time, simply said: 『aging the battery is a decrease in battery capacity 』.

Aging of the battery cell internal battery do what needs to be changed?

The aging batteries, the most frequently observed is the easiest to detect is the change in resistance, the internal resistance of the sony VGP-BPS2 battery when the nucleus is very small factory, but the charge and discharge over a long period, because of electrolyte in the battery, and a swimming pool in electronic activity of chemicals in the lower internal resistance of the whole because of increased electrolyte will gradually repeated load variability of discharge, the resistance will continue increase until the resistance as large as the power of the internal battery is not properly released, a common phenomenon is the mouth of the battery, this time, the battery is the so-called aging and capacity battery will decrease with respect, most of the aging of the battery is because the resistance has been caused in the cause can not be used.

Change of battery internal resistance include the following:

Changes in the cathode materials

The molecular structure of the battery, the positive and negative electrodes can hold rainfall on the hole structure of chemical molecules will gradually with the number of loading and unloading of collapse. Blocking, which is positive and negative active materials, passive, there may even be negative materials are polarized phenomenon, reduces the toshiba PA3383U-1BRS battery charge-discharge process can be free to move the number of ions.

Catalyst for Change

A catalytic role in the molecular structure of the catalyst, due to temperature, humidity, storage time, gradually changing its structure and nature of the final can not be catalytic.

Electrolyte metamorphic

Electrolyte because of the battery after charging and discharging several times, but it was bad, and even the loss, the low quality of basic battery is easier because the composition of the electrolyte under the control of undesirable while the faster deterioration.

Conclusion:

Again, the apple A1185 battery itself as a kind of oral consumption, with the increase in the number used in the battery charge storage capacity, the successive reduction of life cycle support of about 500 times more than the estimates of the time, if the first few days of use, between about 1-2 years we should move to a new battery a.

But for the laptop. The battery is expensive consumables, many people would say that I try to use less battery, or simply do not need batteries, so there is no life cycle of battery problem, but in fact, a This concept is not always the case is correct, the number of batteries affect the battery life conditions, but not the key, because, as mentioned in this article, the battery’s chemical energy of products will evolve with the passage of time, but to reduce its activity, stood not the same because of self-discharge and lead to an excessive discharge, and loss of activity and damage to the canal, so carefully When you pay attention to your battery at the same time, remember the proper use of batteries, but also the Aspire 3000 battery charge and discharge on a regular basis, so your battery to play a greater efficiency.
