Battery-Super Capacitor-based Hybrid E-Vehicle

Abstract

A growing concern in today’s world is environmental protection and energy conservation. Automotive manufacturers are developing alternatives to existing fossil fuel-driven vehicles. This has paved way for the development of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV). While HEVs tend to reduce the emissions from internal combustion vehicles as a result of greater fuel efficiency, they do not completely solve theproblem. Electric vehicles on the other hand are much more energy efficient, produce absolutely no tail pipe emissions and requires less maintenance as compared to the conventional internal combustion engine (ICE) vehicles. However, the reason the automotive industry has not gone pure electric or able to compete favorably with existing gasoline cars, lies in the inherent problem of existing battery technologies. Presently the only viable solution to this problem is to combine a high energy storage device such as an electrochemical battery or fuel cell with a high-power device such as an Electric Double Layer Capacitor (EDLC) or ultra-capacitor or more often called a super capacitor. The research work classified in to two different categories, i.e., simulation in MATLAB and its hardware implementation. In this paper Supercapacitor is connected in parallel with Batteries and its comparison is done. These paper presents simulation on BLDC motor with battery and supercapacitor. Key words – Battery, Super Capacitor, Boost Converter, Electric hybrid vehicles, HESS.
