NOVEL BUCK-BOOST CONTROLLED HESS TO DELIVER CONSTANT HIGH VOLTAGE FOR ELECTRIC VEHICULAR POWER SOURCE

Electric Vehicle which derives power from battery suffers from supply of continuous high voltage energy supply during transient and high load. So this paper details better efficient energy management between Lithium-Ion battery and Ultracapacitor (UC) for Electric Vehicle (EV) applications. This is achieve by using an novel buck-boost controlled method to supply required high voltage by the EV along with the efficient energy management scheme to deliver power from UC whenever high transient is demanded by the EV. Through simulations using MATLAB/SIMULINK, the delivery of high power and efficient energy management is implemented.
