Energy Recovery in Three-Wheeler Electric Vehicle Through Regenerative Braking in Hilly Region

This paper presents an integrated system in a three-wheeler Electric Vehicle (EV) where two modes of Regenerative Braking (RB) energy recovery exist. The first one is the Energy Recovery Mode through FOC (conventional method) and the second is the Efficient Energy Recovery Mode through Reduced Switching (ERTRS). The selection of an RB energy recovery mode depends on the user-defined input. Both the modes have been simulated in MATLAB/Simulink with the existing three-wheeler vehicle data and hilly terrain slope. The ERTRS mode has faster and more efficient braking characteristics. It provides higher energy recovery than the conventional method in the hilly region for the same driving and loading conditions.
