[0002] A battery refers to a cup, trough or other container or part of a composite container that contains electrolyte solution and metal electrodes to generate current. It is a device that can convert chemical energy into electrical energy. It has positive and negative electrodes. With the advancement of science and technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as energy sources, we can obtain current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the battery has a simple structure, is easy to carry, and is easy to charge and discharge. It is not affected by external climate and temperature. The performance is stable and reliable, and it plays a great role in all aspects of modern social life. Compared with fuel vehicles, pure electric vehicles mainly differ in four major components: drive motor, speed controller, power battery, and on-board charger. Compared with gas stations, it has public ultra-fast charging stations. The quality difference of pure electric vehicles depends on these four major components, and their value also depends on the quality of these four major components. The purpose of pure electric vehicles is also directly related to the selection and configuration of the four major components.
