Undervoltage discharge protection

Partial certification program

Undervoltage discharge protection test requirements

CQC certification

The samples were subjected to 500 cycles of testing in the following order:
a) undervoltage discharge;
b) After the protection device is activated, it is allowed to stand for 1 min.
When undervoltage discharge, the discharge current is the standard discharge current (Idr)
The undervoltage shutdown protection circuit of the battery pack should be activated every cycle. The minimum voltage should not be less than the smaller of the battery discharge cutoff voltage of n times or the discharge cutoff voltage of the other group.
