HIL Simulation of an Electric Race Car with Electric Differential and Regenerative Braking

Abstract

This work presents a Hardware-In-the-Loop (HIL) simulation of a Formula SAE electric race car considering the regenerative braking and electric differential. The car model is organized using the Energetic Macroscopic Representation (EMR) graphical formalism. Furthermore, the HIL simulation technique is used to validate the mathematical models of the battery and one electric machine. The effect of real equipment on the operation of the car is analyzed. Besides, the driving cycle and some information on the racetrack is presented. After this, a description of the test bench is presented. Finally, the experimental results obtained in the HIL simulation are compared to the ones obtained from the Matlab-Simulink simulation.
