What should I do if the electric vehicle does not turn on when charging?

Electric vehicles will encounter many problems during the charging process. Among them, the charging does not turn on the light is a common problem. The following author will tell you the reason why the charging does not turn on the light.　　 1. The charger current is too small and the charging time is long. The battery cannot be fully charged within the expected time, causing the charger to not turn on the light.　　2. The charging environment temperature is too high (≥45℃), causing the battery terminal charging voltage to not reach the limit voltage value, and the charging current is always maintained at a large value and cannot be reduced to the inflection point current value, causing the charger to not turn on the light. 3. The charger parameter setting does not match the battery, causing the battery to be overcharged or undercharged for a long time, and eventually cause the battery to lose water, and the charger will not turn on the light (overcharge, direct water loss; undercharge, after salting, 'hot Out of control' loss of water).　　　　 4. Too much acid is stored inside the battery, causing poor oxygen circulation in the battery, causing 'thermal runaway' and causing the charger to charge and not turn the lights.　　 5. The battery has insufficient acidity in its memory, and the charger does not turn on when the battery loses water in the later period of use.　　 6. There is a slight short-circuit inside the battery, causing the battery terminal charging voltage to not reach the limit voltage value, and the charging current is always maintained at a relatively large value and cannot be reduced to the inflection point current value, causing the charger to not turn the light.　　 I believe that everyone has a certain understanding of the non-returning lights on charging. If you encounter this problem in the future, you can solve the non-returning lights caused by the charger or temperature by yourself, and the internal reasons of the battery can consider replacing the battery with good quality and good after-sales.
