A novel configuration of regenerative braking system to improve the energy efficiency of an electric vehicle with Dual­Stator Dual-Rotor BLDC motor

Electric propulsion for vehicles is gaining importance day by day making it right choice for future transportation including rail, road and airways. The major drawback of Electric vehicle is the energy efficiency, which need to be improved in par with gasoline engine to make them economically viable solution for transportation. In the similar lines, this paper proposes a novel configuration of Regenerative Braking System (RBS) to improve the energy efficiency of Electric vehicle with a Dual-stator Dual-rotor BLDC motor. Complete mathematical modeling and simulation of electric vehicle is carried out with the proposed configuration and all the performance indices of the vehicle are derived. The results are very encouraging showing an increment of range by 75% for same battery pack compared to conventional configuration.
