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: Presented are articulating roof assemblies for electrical generator systems, methods for making/using such roof assemblies, and fuel cell powered electric vehicle charging stations with such roof assemblies. An electrical generator system includes a mobile or stationary rigid support frame with an electrical generator that is mounted to the support frame and operable to generate electric power. At least one charging cable is electrically connected to the generator in order to transfer the electric power to a load. A control circuit is communicatively connected to the generator and governs the creation and transfer of electric power. Mounted onto the rigid support frame is a roof assembly with one or more roof panels. Each roof panel is movable between an undeployed position, whereat the roof panel at least partially covers the generator, and a deployed position, whereat the roof panel is obliquely angled to and/or projects outwardly from the rigid support frame.
