Abstract:
A system comprises a battery cell, control logic, and a battery drain latch circuit. The control logic is coupled to the battery cell and determines whether a battery pack has experienced a failure condition. The battery drain latch circuit is activated by the control logic, upon detection of a failure condition, to cause the battery cell to drain energy therefrom.
