Abstract:
A diagnostic system for a battery system having a battery module electrically coupled to a contactor is provided. The battery module has first, second, and third battery cells. The diagnostic system includes a first microcontroller that transitions the contactor to an open operational state if a first battery cell comparator overvoltage flag is equal to a first battery cell analog overvoltage flag value, or a battery module fault line voltage flag is equal to a first battery module fault line voltage flag value.
