Abstract: Apparatus and method for controlling a pyro-fuse. A pyro-fuse control system includes a current sensing circuit and a diagnostic circuit. The current sensing circuit is configured to determine whether the current flowing in conductor exceeds a threshold current. The diagnostic circuit is coupled to the current sensing circuit. The diagnostic circuit is configured to determine whether an indication of current exceeding the threshold current generated by the current sensing circuit is caused by current flowing the conductor and is not caused by a fault in the current sensing circuit.

Abstract: A system includes a battery pack having a first battery module, a second battery module, and a busbar that couples the first and second battery modules; a battery management controller having a first wireless transceiver; and a battery monitor coupled to the first battery module and to the busbar. The battery monitor includes monitoring circuitry configured to receive a first indication of a parameter of the first battery module; a second wireless transceiver configured to provide the first indication to the battery management controller via a wireless connection to the first wireless transceiver; and a busbar voltage circuit configured to receive a second indication of a voltage across the busbar, and, responsive to the second indication being greater than a voltage threshold, provide a first signal to the second wireless transceiver to cause the second wireless transceiver to be in a higher-power state.
