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.
