Design and Implementation of Automated Solar/Fuel Cell Power Controller for Hybrid Electric Vehicle

Abstract

With an ever increasing demand for energy for transportation and alarmingly high levels of pollution caused due to excessive consumption of fossil fuels, the Research & Development in Electric/Hybrid Electric Vehicles is be- ing carried out at an accelerated pace. The success of any of the above approaches will depend on the capabili- ties of the batteries i.e., power density, cost, maintenance and life span etc. This paper proposes a novel, flexible strategy for Multi Objective Control of Power Controller (MOPC) for a Hybrid Electric Vehicle (HEV). Here a new control strategy has been implemented with three different configurations like Constant Fuel Cell Current Mode, Constant Battery Current mode and Constant Battery Voltage Mode. Based on the load demand on the vehicle, control strategy is automatically selected for propulsion or charging purposes, by using computer and interfacing circuits.
