This may be caused by too much current during operation, so that the voltage will be sharply reduced, which will also cause the battery to heat up. The battery is an important part of the car, in the absence of starting the engine, is responsible for the battery for the whole car electronic equipment power supply, the battery is also responsible for starting the engine.
When starting the engine, the starter needs to work, the fuel supply system needs to work, and the ignition system also needs to work, which are inseparable from electricity.
After starting the engine, it is the generator that supplies power to the whole car electronics, and after starting the engine, the generator also charges the battery. The battery is a wearing part that needs to be replaced regularly, the battery on the general car can be used for 3 to 4 years, but the battery of many cars can not be used for such a long time, which is due to the incorrect use of the owner's habits. When the engine is not started, do not sit in the car for a long time to use the electronic equipment in the car.
If it is a slight heat is OK, but if the battery itself is very hot, the aging of the battery, the internal resistance becomes large, the electrolyte dries up, and the internal short circuit causes heat. The battery increases with the number of times it is used, which includes discharge and charging, and it is best to replace the battery with a new one
2) The charger problem, the general charger has no pulse function, and there is no negative pulse to eliminate polarization function
In order to fundamentally solve the battery heat caused by the charger problem, it is necessary to correctly choose the electric vehicle charger, the battery charging process is an electrochemical reaction process, in this process, if the battery appears a small amount of heat is normal heat, if the heat is abnormal, in the case of good battery performance is the charger reason
The battery charging is hot, indicating that the power is large for a long time, the ventilation effect is poor, and the ventilation and cooling should be stopped first, otherwise the consequences are not envisaged.
