Evaluation of Regenerative Braking and its Functionality in Electric Vehicles

Regenerative braking is an efficient method of reusing the kinetic energy of decelerating e-vehicle by restoring the energy into the battery. The recovered energy can be used to supply power to the grid or it can be stored for the future. It reduces the wastage of energy and also helps to increase the traveling distance. BLDC and PMSM motor are used for e- vehicles due to its very good torque-speed characteristics. The mathematical modeling of the BLDC motor is done in this work. The study of vehicle dynamics for the regenerative braking system is done. This electronic commutation process is the same for both motoring and regenerative modes based on Hall sensor output. Our main aim is to have a compatible approach towards the utilization of electric vehicles for mountainous terrain and its comparison with the performance of e-vehicle on the plane region. A comparison between the two terrains will be done based on the inclination between the ground level and slope on which e-vehicle is running.
