What's wrong with the heating of electric car battery charging?

What's wrong with the charging heat of electric car batteries? However, we found no. The electric cars we use every day, its batteries are sometimes very hot, especially when charging, even hot. What is going on today? Let’s take a look at the reasons for the hot charging of electric vehicle batteries! 1. Lack of electrolyte If there is no electrolyte, the normal electrochemical reaction of the battery will be adversely affected, the battery is prone to heat, even deformation, and the service life is terminated early. To this end, you can choose to add electrolyte for maintenance. Generally, high-purity dilute sulfuric acid with a specific gravity of 1.05 is used, because the electrolyte contains iron, copper and other impurities that will cause the battery to short-circuit. This can effectively prevent the lack of battery electrolyte and prevent it from heating during charging. 2. Hybrid electric vehicle chargers Due to the popularity of electric vehicles, many household users have electric vehicles with more than two units, and some users often use 48v chargers for convenience. If the battery is used for 60v chargers, because the voltage is not Matching will cause the temperature of the battery to rise. In addition, the charger is very dangerous and even directly bad the charge. Therefore, a dedicated car charger is recommended. 3. The battery has been aging and damaged since the battery from the General Electric factory, but as time goes by, after the battery has been used for a long period of time, it will be aging or damaged due to various reasons, even if it is within a long period of time at this time. The charge cannot save the battery. The battery will become hotter and hotter. It is recommended to replace the battery, otherwise it will be dangerous. 4. Single battery short circuit If a single battery is short circuited, it will also cause the battery temperature to be too high during charging. In this regard, the correct method is to use a multimeter to detect battery problems. You can choose to replace a single battery, provided of course that there is a battery of the same specification, or the entire battery is to be replaced.
