In automobiles, large amount of energy loss due to braking takes place without any recycling. A brake is required to control the motion of an automobile. The conventional braking system uses friction of brake shoes and drums for conversion of kinetic energy developed by the vehicle into heat energy. In conventional braking system the heat energy generated at contact surfaces is dissipated to surroundings. In regenerative braking system the speed of the vehicle is reduced by the motors. No surplus energy of the vehicle will be wasted as the unwanted heat, the overhead wires receive electricity from the motors which act as a generator. In this paper, a novel technique of pulse width modulation on brushed DC motor is used for evaluating the availability of braking energy recovery. The vehicle receives power from the electrical energy taken from the battery is used by an electric motor that provides motive force to the wheels. To obtain more efficiency the regenerative braking should take place on the vehicle, so a model to control the speed of the motor has been simulated using circuit simulation software Proteus. The laboratory test has been performed on the built model before being mounted on the vehicle. The circuit is repeatedly tested for the desired wave functions and are absorbed on the oscilloscope. Results are presented for the amount of power generated during braking and variation of run speed of the vehicle with time for different rated speeds of the motor at different loads.
