Hydrogen Storage Control Unit
For safe, hydrogen powered commercial vehicles

Tank control unit for hydrogen applications

We have developed the "Hydrogen Storage Control Unit" (HSCU) specifically for commercial vehicle applications. It monitors and controls the refueling process at hydrogen filling stations. Hydrogen is a promising – but also challenging – fuel for sustainable mobility solutions. Our new series production control unit makes a significant contribution to the safety and efficiency of hydrogen-powered vehicles.

Refuel, but safely.

The tank control unit or "Hydrogen Storage Control Unit" is part of the hydrogen tank system and ensures a controlled transfer of hydrogen – from the hydrogen filling station to the installed hydrogen tank storage and on to the combustion engine or fuel cell system. With its monitoring function, the HSCU also guarantees safe hydrogen storage in the vehicle in compliance with legal requirements. Another secondary function of the HSCU is the calculation of the hydrogen SOC ("state of charge").
