Optimization potential for HV vehicle networks by system simulation

Rosenberger brings the ZVEI guideline TLF0101 to life as one of the first suppliers and shows amazing optimization potentials for practice. The guide describes a standardized format for exchanging parameters of electro-thermal component models for the system simulation of the vehicle electrical network. This thermal optimization process can greatly reduce connector size and weight, wire cross-section, and development times depending on the installation situation.

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.
