Overvoltage charging protection

Partial certification program

Overvoltage charging protection test requirements

CQC certification

The battery samples were tested in the following sequence for 500 cycles:
a) overvoltage charging;
b) After the protection device is activated, it is allowed to stand for 1 min.
During overvoltage charging, the charging current is the maximum charging current Icm, charging to n*6.0V or the highest voltage that may be tolerated (both higher).
The overvoltage charging protection circuit of the battery pack should be activated every cycle.
