Electric car charger slight heat is normal, the charger is working, the transformer will always pass the current and voltage, high intensity current will make the transformer temperature rise, so the charger will also heat, of course, if it is charged in a high temperature environment, it will also affect the heat degree of the charger, it is best to charge in a cool place that blocks the sun.
？
If the charger is hot, it may be because the battery and the charger do not match (voltage mismatch), the charging time is too long, the battery electrolyte is missing (internal resistance is too large, the conversion efficiency is low caused by hot), the current and voltage are too large, and the radiator of the charger is damaged. It is recommended to unplug the power first, and try again after the charger cools, or it is very hot on behalf of the charger.
？
The charger must be original, regular, hot charger may also be a quality problem, charging to avoid direct sun or exposure to direct charging, after the end of the ride, the battery should be cooled for half an hour before charging, you can check whether the cooling fan in the charger has rotation, there will be no obvious electrical burning odor.
There is also the problem of the battery, resulting in no charging, the charger does not jump the green light for a long time, etc., of course, if you do not know the specific reasons, it is best to ask the electric vehicle store or after-sales store for professional maintenance.
1 Heat is normal
2 Electric car charger needs to convert electrical energy into chemical energy stored in the battery when charging, this process is inevitable will produce a certain amount of heat.
At the same time, the components inside the charger will also heat up due to the current passing through.
3 Under normal circumstances, the heat of the charger will not exceed a certain range, if it exceeds this range, it is necessary to pay attention to whether there is a fault.
At the same time, pay attention to safety when using the charger to avoid safety accidents caused by high temperature.
normal
If the electric car charger is slightly hot, it should be a normal phenomenon, but if the charger is very hot, it is abnormal. If the charger is hot, please check whether the battery and the charger do not match. When charging electric vehicles, try to use the original charger to charge.
