Battery, Ultra-capacitor based Hybrid Energy Storage System (HESS) for EV applications with PI and Fuzzy logic controllers

The extensive use of vehicles based on IC engines has contributed to serious effects the environment and accelerated depletion fossil fuel reserves which led a rapid increment in cost over past few decades. By consideration these undesirable effects, automotive industry will move towards electrified drivetrains for obtaining zero-emission higher efficiency. In vehicles, drive is coupled entirely partially by e-motors powered energy storage sources. choice simple structured HESS topology make better understanding power flow controlling circuits limits existing sources contribute electrification drive. main intention this paper, excessive current required motor draw from ultra-capacitor without burdening battery. This improve efficiency also smooth running document examines feasibility capacity integrates battery units through PI Fuzzy controllers.
