Emulating electric vehicle regenerative and friction braking effect using a Hardware-in-the-Loop (HIL) motor/dynamometer test bench

摘要

This paper provides a new approach for emulating electric vehicle (EV) braking performance on a motor/dynamometer test bench. The brake force distribution between regenerative braking and friction braking of both the front and rear axles are discussed in detail. A brake controller is designed, which represents a very close model of an actual EV braking system and takes into account both regenerative and friction braking limitations. The proposed brake controller is then integrated into the existing controller of an EV Hardware-in-the-Loop (HIL) test bench, and its performance is validated in real-time using the same experimental setup.
