Solutions to electric vehicle heating

Short circuit of single battery
If a single battery is short circuited, the battery temperature will be too high when charging. In this regard, the correct way is to use a multimeter to check the problem battery, you can choose to replace a single battery, of course, the premise is that you have a battery of the same specification performance, otherwise you can only choose to replace it.
In fact, in life, only pay more attention to strengthen the maintenance of the battery, in order to let the battery play a great role.
Battery aging or damage
As we all know, since the battery is not allowed to add heavy metals such as cadmium, the service life of our battery has been greatly reduced. In addition, some electric vehicles in use after a few years, the battery has already appeared aging or damage, then the battery at this time to replace, and then choose to charge, it can no longer absorb. Therefore, the temperature will be too high when the battery is charged.
Lack of electrolyte
If there is no electrolyte, the battery resistance will increase and heat during the charging and discharging process, which will affect the battery life. For this, you can choose to add electrolyte stock solution, generally 1.25-1.28 dilute sulfuric acid, which needs to be of high purity. Some impurities, such as iron and copper, are very bad for the battery. After opening the cover, add 10ml to each hole, do not add more, not the more, the better. This can only avoid the lack of electrolyte, so that the battery does not heat, does not increase the capacity, can slightly extend the life of a few months. If you really want to increase the capacity, you need to replace it.
Charger and battery do not match
Due to the popularity of electric vehicles, many users have more than two electric vehicles in their homes, and some users often mix chargers for convenience. Electric vehicle manufacturers remind that if the battery is 48V and 60V charger is used, the battery temperature will rise due to voltage mismatch. In addition, this practice is very dangerous, even directly charging the electric vehicle. Therefore, it is recommended to use charger for special vehicle.
