Abstract: Electric Vehicle (EV) brings zero emission concepts as positive result of electric motor propulsion system. Zero emission concepts can not only be applicable to a built in EV but also in converting a fossil fuelled vehicle into its electric version. Brush Less DC motor (BLDC) have been demanding as in-wheel motor in EV because of its high efficiency, desired torque versus speed characteristics, high power density and low maintenance cost. The major disadvantages voiced by the existing system are the charging woes, travelling range, overloaded batteries, lack of power, pollution. To tackle theses disadvantages so as to improve the driving range of EV along with efficient usage of energy a creative supervisory energy management strategy for Hybrid Energy Storage System (HESS) comprising of battery and super capacitor is proposed. Moreover a new Regenerative Braking System (RBS) is incorporated for a two-wheel EV with HESS driven by BLDC motor. The BLDC motor control is utilized with the traditional Proportional-Integral-Derivative (PID) controller while the distribution of braking force is determined with the fuzzy logic control. In this paper the battery state of charge, super capacitor state of charge, braking force and dc bus current are analyzed. Simulation results prove the effectiveness of proposed system and all the results are validated.
