US 2020/0052349 A1 · 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.

Dependent claims

An electrical power management system for a vehicle, comprising:

a control circuit configured to monitor and control power to a battery bus of the vehicle;
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;
and
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.

1 more element

A method of operating an electrical power management system for a vehicle, the method comprising:

receiving data indicating an electrical condition of a battery bus of the vehicle, the battery bus coupled to a first battery via a first coupler and coupled to a second battery via a second coupler, the second battery having a second battery chemistry distinct from a first battery chemistry of the first battery;
and
sending a first control signal to the first coupler and a second control signal to the second coupler to control power applied to the battery bus from the first battery and from the second battery responsive to the electrical condition.
