1. Most of the cases because the battery car itself is not ultra-low-temperature rechargeable battery, during the ultra-low temperature natural environment, due to the low temperature of the battery, the internal resistance of the battery results in the mechanical chemical characteristics of the internal resistance of the battery, resulting in internal resistance of the battery Suddenly lowered, even invalid. This area can be rotated to an appropriate temperature.
After a period of time, the rechargeable battery will repair a part of the work ability, often use, the rechargeable battery will be more severely attenuated or accounting due to ultra-low temperature lithium precipitation life. 2, battery car lithium ions often completely power out, is said to be overcharged and discharged, this personal behavior causes charging battery to charge without charging, that is, rechargeable batteries, leading to rechargeable batteries Attenuation coefficient is too fast, long service life. This non-changing battery.
3. Due to the common fault of the charging interface, short-circuit faults can cause battery car lithium-ion battery protection board to open the dimension, can not charge, not to repair. 4.
There is a problem with the battery car lithium ion charging head, and it is proposed to check the charging head.
