How to solve the problem of not charging the lithium-ion battery of electric vehicles

1. In most cases, the battery car itself is not an ultra-low temperature rechargeable battery. When used in an ultra-low temperature natural environment, the internal resistance of the battery is frozen due to the low internal temperature of the battery, which causes the mechanical and chemical characteristics of the internal resistance of the battery to decrease, resulting in the internal resistance of the battery Suddenly lowered or even failed This area can be rotated to an appropriate temperature. After a period of time, the rechargeable battery will repair part of its working capacity. Frequently used, the rechargeable battery will have a more serious attenuation coefficient or billing due to the ultra-low temperature lithium ion precipitation. 2. The application of battery car lithium is often completely out of power. It is said that the battery is overcharged and discharged. This personal behavior causes the rechargeable battery to be charged when the charging head is normal, that is, the rechargeable battery is often in a state of high power consumption, which causes the rechargeable battery to attenuate The coefficient is too fast and the service life is too long. The battery must be replaced. 3. Due to the common faults of the charging interface, short-circuit faults will cause the battery car lithium-ion battery protection board to turn on by itself and cannot be charged and must be repaired. 4. There is a problem with the lithium charging head of the battery car, it is recommended to check the charging head first.
