The “Hy4Drive-System” is an electronic Drive Management System for the Hydrogen Bus HYDRON, completely developed in-house by the technicians of Italian ebus specialist Rampini. Basically the vehicle functions like a battery bus with a robust 170 kWh LFP-battery, but it is coupled with a 30 kW Fuel Cell. In order to accomplish the most flexible and efficient way to integrate the Fuel Cell into the Drive System, the “Hy4Drive-System” offers four different modes of usage of the Fuel Cell and thus of the whole Drive System. As the first compact H2-Range Extender vehicle in a booming hydrogen market, the flexible Drive-System demonstrates that also small bus builders can be very innovative.
