An Approach for Electric Vehicle Range Enhancement using Solar PV and Regenerative Braking Operation

SPV-powered electric vehicles with regenerative braking are good for the enhancement of battery range in the Indian Context. The regenerative method of braking of an electric vehicle (EV) helps in the efficient utilization of the battery power to increase the range of the vehicle. Methods presented in the study for the regeneration of power during electrical braking are designed to deal with the power flow during the alteration from the motoring to the regenerative braking mode of PM BLDC motor-driven EV. PMBLDCM (permanent-magnet brushless DC motor) has advanced characteristics in comparison to DC & induction motors and therefore becoming popular for a wide range of EV applications. This paper presents a solar PV fed BLDC motor based EV drive with InC based MPPT scheme for efficient and optimum power generation and regenerative braking mechanism. The overall scheme operates in two modes, the first mode is driving mode in which the battery can receive power from both SPV and regenerative braking and the second mode is charging mode in which the battery receives power from a conventional three-phase fast charger. The proposed scheme is simulated in a MATLAB-Simulink software environment and the obtained results are presented to prove the effectiveness of the proposed drive.
