SHORT DETECTION IN BATTERY CELLS

Internal shorts and other failures in lithium-ion battery cells may be detected during balancing of the battery cells. A counter may-be used to detect when a battery cell is behaving differently than other battery cells by balancing more or less frequently.

This misbehaving battery cell may be faulty due to an internal short. If the faulty battery cell is not corrected by replacement with a different battery cell or corrected by a user resetting the counter, the misbehaving battery cell may be disconnected to prevent the overheating event.
