Battery/Supercapacitor Energy Management system for Electric Vehicle

Abstract

Electric vehicles (EVs) require appropriate design and sizing of their energy sources and proper management. The solution will be an energy efficient with cost-effective, increased lifespan, and an increase in the vehicle’s range. As per theory of evolution the model and rating calculations are discussed. Also this paper addresses the distribution of power within two energy sources, adopting a converter. Only one energy element unable to meet each preferred parameters. In addition to assisting electric vehicles in acceleration, the Hybrid Energy Storage System captures regenerative braking energy. By controlling the current of battery as consistent as viable at the time of picks, power management is primarily concerned with reducing battery stress and merging supercapacitors to supply instantaneous current at the time of pick and to recover power during deceleration. According to the results of HESS and experimental setup, current of battery is controlled as consistent as at the time of acceleration when the power management algorithm is implemented. In other words, only normal current is provided by the battery at the time of picks, while transitory current is provided via the ultracapacitor during acceleration.
