In this paper, we designing and developing controller and converter for the electric vehicles. In the electric vehicle battery is used as the energy source, by using of this battery operating electric motor. If we connect this battery direct to motor without any control device then it causes some unwanted problems in EV’s. Because of the output voltage of battery is not suitable to operating Electric vehicles. Which means without any control mechanism the output voltage cannot be controlled and it will give divergence in output voltage in terms of error signal. Its result battery output power will reduce and therefore the performance of electric vehicle is go down in terms of power torque to drive vehicle. So in electric vehicle use of control mechanism is mandatory to control the output voltage of battery and that can achieve proper power and torque by a proper feedback control system. But price of the EV’s are to much high higher the electric vehicle because of battery, motor and EV Controller.
