The HV vehicle network can already be virtually dimensioned with this system simulation at the time of specification. The successive reduction of the cable cross-sections shows a considerable optimization potential - with the use of the Rosenberger HVS®240 connector with 50 mm² cross-section, for example, volume and weight savings of 30% as well as a reduction of the cable cross-sections of almost 50% could be achieved compared to the original design.
To verify the simulation models, Rosenberger and Leoni developed a demonstrator - consisting of cable, connector and power unit. In the process, the calculated saving potentials could be confirmed in practice.
On request, Rosenberger will provide these parameters in accordance with the ZVEI guideline for the HV product portfolio.
