When Does The Electric Vehicle Battery Need To Be Maintained And Charged?

The electric vehicle battery needs to be maintained and charged when one of the following situations occurs: (1) The battery capacity decays and decelerates too fast; (2) The battery is lagging behind; (3) After the battery loses fluid, refill it; (4) After the battery is placed for a long time; (5) After the battery is seriously over-discharged; (6) The battery is working in a low temperature environment for a long time; (7) The charging parameters are unreasonable and under-charged for a long time; How to set the charging parameters for maintenance charging; Stage constant current charging. The parameters of the pre- and mid-charging are basically the same as those of the car-equipped charger, except that the maximum charging voltage is increased to a higher value in the later stage of charging. That is, using WD charging, deep charging to repair the battery that has fallen behind. Maintenance charging is also called equalizing charging.
