What is the serious imbalance of high-voltage batteries?

The serious imbalance of high-voltage batteries is that the battery of the car can only travel a short distance after being fully charged. For example, the vehicle battery of BYD e6 can only travel about 80 kilometers after being fully charged. It can be repaired by using the maintenance computer to diagnose the fault code.

　　

Electric vehicles include fuel cell vehicles, and power vehicles, solar vehicles, etc., with relatively low exhaust emissions, all of which use unconventional vehicle fuels as power sources. With the continuous development of the automobile industry, lead-acid batteries have developed into maintenance-free batteries, and no need to add electrolyte or distilled water. The daily maintenance of ordinary lead-acid batteries is frequent. It is necessary to check the concentration of the electrolyte and the height of the liquid level. If the liquid level is lower than the standard scale line, distilled water needs to be added.
