After charging the battery car does not remove the charging device, it will not automatically power off, and the charging device will continue to charge the battery. The charging device has a protection device, which automatically breaks off the main charging device after it is full and enters the floating charging state. Floating charge is a continuous, long time constant voltage charging method. The floating charging voltage is slightly higher than trickle charging, which is enough to compensate for the self-discharge loss of the battery and can quickly restore the battery to the nearly fully charged state after the battery discharge.
The electric vehicle lead-acid battery charger has an automatic power off function. The specific working principle is to use voltage balance to control the output of the power supply, when the battery voltage is lower than the charger output voltage, the charger current begins to output, charging work, once the battery is full, the battery voltage and the charger output voltage to maintain balance, then the automatic balance cut off the power module starts to work, cut off the power when the electric vehicle stops charging work.
Electric vehicles have charging protection function, the battery is full of automatic power off
