1. A method, comprising:
selecting, by a controller, an off-battery battery management system (BMS) to which to transmit parameter data associated with a battery of a system;
transmitting, by the controller, the parameter data to the selected off-battery BMS;
receiving, by the controller, an off-battery battery state determination from the selected off-battery BMS;
receiving, by the controller, an on-battery battery state determination from an on-battery BMS:
determining, by the controller, a battery state based at least in part on the off-battery battery state determination and the on-battery battery state determination; and
causing operation, by the controller, of the system based at least in part on the determined battery state.
