Abstract: An electric motor and energy management control system for use with at least one rechargeable battery and at least one hydrogen fuel cell in an electric powered marine vessel. A processor is configured to receive: a drive signal from a throttle unit in response to an operator command; a signal from a sensor connected a hydrogen fuel cell to provide a status. The processor is use transmits the output drive signal to a motor controller which is operative to supply a DC source to an electric motor of an electric powered marine vessel, to receive the output drive signal from the processor, and in response to the output drive signal to selectively switch between providing a DC supply from the rechargeable battery and/or a DC supply from the hydrogen fuel cell in order to optimize an available DC source to supply the electric motor.

Abstract: The present invention provides an electric motor and energy management control system for use with at least one rechargeable battery and at least one hydrogen fuel cell in an electric powered marine vessel. The electric motor and energy management control system comprises a processor configured in use to receive: a drive signal from a throttle unit in response to an operator command; a first signal from a first sensor connected to at least one rechargeable battery to provide an indication of battery level status; and a second signal from a second sensor connected to at least one hydrogen fuel cell to provide an indication of hydrogen fuel cell status. The processor is operative to derive an output drive signal from the drive signal level and from the first and second signals. The processor in use transmits the output drive signal to a motor controller. A motor controller is operative to supply a direct current source to at least one electric motor of an electric powered marine vessel.
