How to solve the problem of excessive charging of electric vehicle battery?

1. Lack of electrolyte

If the electrolyte is lacking, the battery will increase in resistance and heat during charging and discharging, which will affect the battery life. In this regard, it is possible to add an electrolyte stock solution, generally 1.25 to 1.28 of dilute sulfuric acid, which must be of high purity, and some impurities are very bad for the battery, such as iron and copper. After opening the lid, add 10ml to each well. Don't add, not as much as possible. This can only avoid the lack of electrolyte, so that the battery does not heat, and cannot increase the capacity, can extend the life of a few months. Really want to increase capacity, must be replaced.

2, the charger and battery do not match

Due to the popularity of electric vehicles, many users have more than two electric vehicles, and some users often mix chargers for convenience. If the battery is a 60V charger, the battery temperature will rise due to voltage mismatch. In addition, this practice is very dangerous, and even directly burns the electric car. Therefore, it is recommended to use a special charger for the car.

3. The battery is aging or damaged.

Everyone knows that since the battery does not allow the addition of heavy metals such as cadmium, the service life of everyone has dropped a lot. Coupled with the fact that some electric vehicles have been aging or damaged after a few years of use, then the battery will be replaced when it is replaced, and it can no longer be absorbed. Therefore, there is a possibility that the temperature is too high when the battery is charged.

4, a single battery short circuit situation

If a single battery is short-circuited, it can also cause the battery temperature to be too high during charging. In this regard, the correct way is to use a multimeter to find the problem battery, you can choose to replace a single battery, of course, if you have a battery with the same performance, otherwise you can only choose to renew.

In fact, in life, only pay more attention to strengthen battery maintenance, in order to maximize the performance of the battery.
