Abstract

Regenerative braking is one of the important features for electric vehicle. It serves to convert part of mechanical energy as known as kinetic energy into electric energy during braking. This energy can be stored in device such as rechargeable battery or any storing devices such as super-capacitor for EV improvement. So regenerative braking plays an important role in reducing the energy consumption of EV. It also will increase the driving range and improve its performance. Research forces on electrical vehicles due to the energy crisis. The regenerative braking energy was used to improve the efficiency of an electric vehicle as it recovers energy that could go to waste. A new method of regenerative braking system was tested for a small scale electrical remote control car. The proposed system use an ultra-capacitor bank to absorb and store energy which could be used to regenerate back to the motor to reduce the battery usage due to higher voltage and the higher starting current required by the Brush DC motor for starting. When motor accelerates in regenerative mode, the switching frequency of the current place an important role in controlling the negative torque applied by the motor. The research will show that the proposed regenerative braking system is important in recover energy losses and improve the torque performance than before by 40%. This project involved mechanical, electrical design and construction. Till the end of this project all development and result including analysis, conclusion and recommendation for future have been made in this report.
