Design and Implementation of SEPIC Converter with Low Ripple Battery Current for Electric Vehicle Applications

This paper focuses on the energy management of battery for electric vehicle applications. The ultra capacitors are used in electric vehicle which protects the batteries from high peak current and therefore extend the life time of battery. The combination of ultra capacitor and battery are used to improve the power density in electric vehicles. The proposed system contains SEPIC converter which reduces the losses of converter and battery current ripple is minimized. The energy of electric vehicle consumption is increased due to converter losses.
