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: A method to control an output voltage of a DC-DC converter, and voltage control logic operable to generate a voltage command to implement the control method, the method including sensing a voltage of a bus of an electric-drive vehicle; increasing a command voltage signal from the sensed voltage to a nominal voltage during a first time period; increasing the command voltage signal from the nominal voltage to a desired voltage during a second time period greater than the first time period; and generating a voltage output based on the command voltage signal.

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.
