1. A system, comprising:
a battery pack including a first battery module, a second battery module, and a busbar coupled to the first battery module and the second battery module;
a battery management controller, including a first wireless transceiver; and
a battery monitor coupled to the first battery module and to the busbar, the battery monitor including:
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 transition from a lower-power state to a higher-power state.
