This may be just the ultimate fantasy. Roewe E50, for example, a cell phone battery capacity is 1 amp, and a car battery cell is 20 amps. E50 car battery pack is about 300 cell, which is 6,000 times the cell phone battery. To shorten such a huge gap, I am afraid that human technology can do it. What is the cost of the battery? Li Jun, director of FAW Technology Center, told reporters that the cost of a 1 kWh battery is about 2,000 yuan, and the cost of a 10 kWh battery is 20,000 yuan. Let 10 kwh electricity to achieve 50 km mileage, the weight of only 1000 kg the following vehicles; more than 1000 kg of car would have installed 20 kwh battery. The average A -class car weighs about 1350 kg or 1400 kg, which means that it has to be installed with 25 to 30 kWh of battery. The cost of the battery is only 70,000 yuan. Zhang Dong, head of the Roewe E50 project, told reporters that the battery cost is gradually declining, but it has not yet reached a level enough to compete with the internal combustion engine. How long is the battery life? People who buy traditional cars are basically not worried about replacing the engine, but people who buy electric cars are worried about the battery life. According to Xiao Chengwei, an expert in the overall expert group of electric vehicle major projects of the National “ 863 †program, the capacity of the battery will become smaller and smaller as the battery is continuously charged and discharged. When the battery capacity is less than 80% , it is not suitable for use as a power source for electric vehicles. According to a report by the German Solar and Hydrogen Energy Research Center, in existing electric vehicles, the life of other components is usually around 10 years, which is longer than the life of the battery. For the consumer's concerns, the auto company's answer is "the battery life is different depending on the use situation, such as the driving habits of the owner, the weather and other factors." After about 10,000 cycles, the capacity of the BYD iron battery can still reach the initial capacity. 70% , still working. Even if you charge twice a day, it will only be 730 times a year. You don't have to worry about using it for more than ten years. Jianghuai Automobile vehicle performance test director railing also told the media that, from the experimental point of view, five years 100,000 km battery life can be guaranteed. Is it expensive to replace the battery? During the warranty period, if the battery has quality problems, the car manufacturer will replace it free of charge. However, after the warranty period, the fee will be charged. The amount of the fee depends on the degree of battery damage. At present, electric vehicle manufacturers have a long warranty period for batteries, and some even reach 10 years, in order to avoid consumers' concerns about replacing battery costs. But if it is really necessary to change the battery, if the battery price is still high, it is better to change a car directly. How to deal with the scrapped battery? At present, scrapped batteries are mostly recycled by automobile manufacturers. Scrapped batteries are simply not suitable as a driving source, but can still be used in other areas, such as power storage in power plants. Japan has taken the lead in the secondary use of batteries, and China has no good solution. If you can't reuse it, just disassemble the battery and recycle the metal, there is basically no profit at all. How can I tell if the battery is broken? Significantly lower battery efficiency and significantly shorter mileage are the main features of battery damage. If you find the above symptoms, it is recommended to drive to an authorized repairer for inspection.
