A high voltage power management module 100 supplies power to one or more motors 118 for driving a fuel cell electric vehicle (FCEV). An E-machine interface subsystem 110 exchanges DC power with an inverter 116 that provides AC power to the motor(s) for driving a drivetrain of the vehicle. A storage interface subsystem 102 exchanges DC power with an electrical energy store 112 (e.g. battery) for providing transient power to drive the vehicle. A fuel cell interface subsystem 104 receives DC power from a fuel cell stack 114 of the vehicle that directly drives the motor(s) through the E-machine interface subsystem. A switching module 106 directs the voltage between the DC power of the storage interface, fuel cell interface and E-machine interface subsystems. The switching module can rapidly switch between, or simultaneously combine, DC power from the storage interface and fuel cell interface subsystems to provide DC power to the E-machine interface subsystem to drive the motor(s). Control circuitry 108 is coupled to, and controls, the switching module to select, or combine, a source of DC power from the electrical energy store and the fuel cell stack to provide DC power to the E-machine interface subsystem.
