Modeling and Integration of Electric Vehicle Regenerative and Friction Braking for Motor/Dynamometer Test Bench Emulation
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 controller of an EV hardware in the loop (HIL) test bench, and its performance is validated in real time. The effect of adding the brake model is further investigated by comparing the experimental HIL energy consumption results with those obtained from ADvanced VehIcle SimulatOR (ADVISOR)
