The hot temperature of the train is not very high, then it is normal, and if it is very high, it means that there is a problem. So what exactly causes the battery to overcharge and burn? The old master tells you that there are generally four reasons!
1, lack of electrolyte If the lack of electrolyte, the battery in the charge and discharge process, will lead to increased battery resistance and heat, affecting the battery life. In this regard, you can choose to add electrolyte stock, generally 1.25 ~ 1.28 dilute sulfuric acid, must be high purity, some impurities are very bad for the battery, such as iron and copper. After opening the lid, add 10ml per hole, not more, not more is better. This can only avoid the lack of electrolyte, so that the battery does not heat, and can not increase the capacity, can slightly extend the life of a few months. To really increase capacity, you have to replace it.
2, charger and battery mismatch Due to the popularity of electric vehicles, many users have more than two electric vehicles, and some users for convenience, often mix the charger, if the battery is 48V with 60V charger, due to voltage mismatch, it will cause the battery temperature rise, in addition, this practice is very dangerous, and even directly charged bad electric vehicles. Therefore, it is recommended that special car charger.
3, battery aging or damage As we all know, since the battery is not allowed to add cadmium and other heavy metals, our service life has declined a lot. In addition, after some electric vehicles have been used for a few years, the battery has been aging or damaged, then the battery is time to replace, and then choose to charge, it can no longer absorb. Therefore, there will be excessive temperature when the battery is charged.
4, a single battery short circuit If a single battery short circuit, charging will also cause the battery temperature is too high. 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, the premise is that you have a battery with the same specifications, otherwise you can only choose to replace it. In fact, in life, only pay more attention to strengthen the battery maintenance, in order to make the battery play the maximum efficiency.
