In a joint research project, the EDAG Group and Hexagon Purus (a specialist in composite high-pressure tanks) are investigating hybrid storage systems that combine the advantages of both hybrid and battery drive alternatives. The project, scheduled to run for 18 months, will develop a flexible storage system, designed to be installed in a vehicle floor, that features batteries and hydrogen pressure tanks installed in parallel.
The vehicle will be able to cover daily distances with battery electricity and long journeys with energy from a fuel cell supplied by hydrogen tanks.
This solution is based on the EDAG ScaleBase vehicle platform.
The only thing that is predefined in SCALEbase is the distance between the front wheel and the heel point. All other measures of length and width can be varied, as the steel structure makes extensive use of sections, making it possible for the floor assembly to be scaled to fit just about any mid-range or luxury-class EV.
Local concept, dimensioning, design and factory planning requirements imposed on the vehicle by an automaker can also be taken into account. EDAG says SCALEbase is also suitable for the structural integration of battery systems, and meets all crash requirements.
