Test the battery in the following order of 500 cycles:
a) Overvoltage charging;
b) After the protection device acts, stand for 1min
During over-voltage charging, the charging current is the maximum charging current ICM, charging to n * 6.0V or the highest voltage value that may be borne (whichever is higher), ,
The overvoltage charging protection circuit of the battery pack shall act during each cycle.
