Abstract: Presented are mobile charging stations for recharging electrified vehicles, methods for making/using such mobile charging stations, and parking facilities equipped with such mobile charging stations. A mobile charging station includes a frame with multiple drive wheels and a prime mover operable to drive the wheels to propel the charging station. A hydrogen storage container and fuel cell are mounted to the frame. The fuel cell oxidizes hydrogen received from the storage container to generate electrical current. An electrical coupling mechanism connects the fuel cell to a traction battery pack of an electric-drive vehicle. A resident or remote controller is programmed to receive charge requests to recharge vehicles, and responsively determines path plan data for the mobile charging station. The controller commands the prime mover to propel the mobile charging station from the charger's origin to a charger destination, and enables the fuel cell to transmit electrical current to the vehicle.

Abstract: A mobile fuel cell system includes a fuel cell generator generating a stack output signal. Multiple boost converter circuits converting the stack output signal into multiple recharge signals while in a first mode. A boost converter circuit converting the stack output signal into a local signal while in a second mode. Multiple charging handles connectable to multiple electric vehicles. A switch circuit presenting the recharge signals to the charging handles, remove the recharge signals from the charging handles and present the local signal while in the second mode. An auxiliary load may be connected to the fuel cell generator and the switch circuit. A rechargeable energy storage circuit powers the auxiliary load while in the first mode and stores energy received in the local signal while in the second mode. The auxiliary load is powered with the local signal while in the second mode.
