Regenerative Braking in Electric Vehicles

Abstract

This paper deals with the implementation of regenerative braking in electric vehicles using PMDC motor. Regenerative braking is the transformation of the vehicle’s energy when the brakes are applied into a stored energy in the battery, which can be used for some other applications within the vehicle. Short range distance covering characteristics of EVs has always beem a major setback for electric cars gaining popularity among users. The exclusive property of a hybrid electric vehicle to recover the energy lost in the form of heat when the driver applies brakes is a major advantage of a hybrid electric cars and has an edge over the other electric vehicles in the market. This problem is solved by increasing the range of these cars. The majority of the kinetic energy kept in a moving vehicle is wasted as heat and some part of it is absorbed by rolling resistance, mechanical friction and aerodynamics of the vehicle. The present day development to merge the drivetrain and brake systems to provide better traction and stability control can be made simpler with the use of electric drive operation. In this process we use simulation tools like simulink and solid works before going for real time circuit. Aim of this project is to create a sustainable future EV which will be a solution to the fuel crisis in near future
