What is the control method of overcharge?

2021-04-27

1. Peak voltage control: Determine the end of charging by detecting the peak voltage of the battery;
2.dT/dt control: Determine the end of charging by detecting the peak temperature change rate of the battery;
3.T control: When the battery is fully charged, the difference between the temperature and the ambient temperature will reach the maximum;
4.-V control: when the battery is fully charged and reaches a peak voltage, the voltage will drop a certain value
5. Timing control: control the end point of charging by setting a certain charging time, generally set the time required to charge 130% of the nominal capacity to control;
6. TCO control: Taking into account the safety and characteristics of the battery, it should be prevented from charging at high temperatures (except for high temperature batteries), so charging should be stopped when the battery temperature rises by 60.
