Abstract

Provided is a power management system of an aircraft ground support vehicle. The power management system includes a power production control module in communication with a fuel cell system of the aircraft ground support vehicle to control production of electrical power by the fuel cell system. The fuel cell system may be configured as a sole source of power to directly power a traction system of the aircraft ground support vehicle and to provide electrical power to an auxiliary power output of the aircraft ground support vehicle. The power management system further includes a power distribution control module in communication with the fuel cell system to control distribution of the electrical power between the traction system and the auxiliary power output. The aircraft ground support vehicle may include a chassis, the traction system, the auxiliary power output, the fuel cell system, and the power management system.
