Heterogeneous battery system and method

Abstract:

An electrical power management system for a vehicle and method of operation are described. The electrical power management system includes a control circuit configured to monitor and control power to a battery bus of the vehicle. The electrical power management system also includes a first coupler configured to be coupled to a first battery and to the battery bus, the first coupler responsive to the control circuit to selectively couple the first battery to the battery bus, the first battery having a first battery chemistry. The electrical power management system includes a second coupler configured to be coupled to a second battery and to the battery bus, the second coupler responsive to the control circuit to selectively couple the second battery to the battery bus, the second battery having a second battery chemistry distinct from the first battery chemistry.
