Abstract: A system is provided for performing an electric power charging process for one or more electric devices. Included in the system is a charging system installed on-board the electric vehicle. The charging system is configured to receive electric power from the electrified vehicle's powertrain, convert the received electric power into an electric current capable of charging the one or more electric devices, and charge the one or more electric devices based on the converted electric current.

Abstract: An inverter system is provided such that the system includes a direct-current (DC) voltage supply, an inverter, an electric machine such as a motor, and a controller coupled with the inverter. The inverter has four or more legs, each with two switches operating complementary to each other. The controller can determine which three of the four or more legs are selected to operate the inverter and uses a remaining one of the four or more legs to operate the inverter by activating/deactivating certain switches during null vector state.

Abstract: The present disclosure generally relates to systems and methods for implementing power a power split between a first and a second power source in a fuel cell powertrain system. The method includes receiving an input into a processor of the fuel cell powertrain system, determining an output by the processor, communicating the output by the processor to a system controller and determining a power split by the system controller. The first power source includes a fuel cell system and the second power source is selected from a battery system or an engine, and the input includes a life or health of at least one of the first power source or the second power source.
