BATTERY PROTECTION CIRCUIT FOR USE WITH BIDIRECTIONAL POWER CONVERTER
A battery is electrically coupled to a bidirectional power converter (i) to output discharge current through a first electrical path between battery cells and the bidirectional power converter, and (ii) to receive charging current through the first electrical path from the bidirectional power converter. A battery management system is configured to monitor the battery cells, detect a fault condition of the battery cells, transmit a first control signal to the bidirectional power converter to control the bidirectional power converter to cease operating in response to detecting the fault condition of the one or more battery cells, and transmit a second control signal to a switching element to close the switching element to cause a short circuit between a positive side and a negative side of the battery to cause a first overcurrent protection device to open to prevent current from flowing into or out of the battery cells.
