Overcurrent charging protection

Partial certification program

Overcurrent 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.
When overvoltage charging, the charging current is 1.5 times the overcurrent charging protection current (1.5Icp), and the charging voltage is the charging upper limit voltage (Uup).
The overcurrent charging protection circuit of the battery pack should be activated every cycle.
