Designing a Battery Emulator/Tester from Scratch to Prototyping to Automated Testing within a HIL Digital Twin Environment

Developing and testing of high-voltage power supply systems becomes costlier and more timeconsuming due to their increased complexity. Therefore, new methods are required to decrease development time and optimize production processes. This paper shows how to design a battery emulator/tester system from scratch to prototyping to test automation within a HiL digital twin environment. A novel Dual-Mode switching topology and its advantages will be explained. The congruence of HiL system and model-based controller parameter tuning will be shown. Automated evaluation of dynamic performance will be illustrated.
