Abstract
A method of handling a fault in a battery pack, the method comprising: a battery module supplying a voltage to a high-voltage circuit; a battery management system transmitting a heartbeat signal to the battery module via a fault bus; the battery module preventing the heartbeat signal from being transmitted back to the battery management system in response to the battery module detecting a critical condition; and the battery management system shutting off the supply of voltage from the battery module to the high-voltage circuit in response to the battery module preventing the heartbeat signal from being transmitted back to the battery management system. The battery module transmits battery data to the battery management system via a communication bus, which is distinct from the fault bus, and the battery management system transmits one or more commands to the battery module via the communication bus.
