Real-time simulation of EV propulsion systems in RT-LAB OP4510

RT Spotlight Zurich - ​​Simulation is widely used for the development of modern electric drives that constitute electric vehicle (EV) propulsion systems. Using conventional offline simulation, it is possible to design and fine tune their controllers, and also to evaluate system performance under steady state and short transient conditions. However, in the EV context, it can be of great interest to analyse the performance of the power system and its control and modulation algorithms under realistic driving conditions, as this can provide valuable information regarding efficiency, autonomy and thermal cycling, among others. However, driving cycles include long transient conditions that are unfeasible to be simulated in a reasonable time frame when conventional simulation approaches are followed. Considering all these, the experience of the Applied Electronics Research Team (UPV/EHU) regarding real-time simulation of EV propulsion systems in an OP4510 platform is covered in this presentation, with special emphasys on implementation details and on the usage of the eHS solver for this purpose.
