Review on Electric Hybrid Vehicle

Abstract

 The rapid consumption of fuel and increased environmental damage caused by it have given a robust impetus to the expansion and development of fuel-efficient vehicles. Hybrid electric vehicles (HEVs) have evolved from their inchoate state and are proving to be a promising solution to the intense existential problem posed to the earth. Not only do HEVs provide better fuel economy and lower emissions satisfying environmental legislations, but also they dampen the effect of rising fuel prices on consumers. HEVs combine the drive powers of an indoor combustion engine and an electrical machine. The most components of HEVs are energy storage system, motor, bidirectional converter and maximum point trackers (MPPT, just in case of solar-powered HEVs). The performance of HEVs greatly depends on these components and its architecture. This paper presents an in depth review on essential components utilized in HEVs like their architectures with advantages and drawbacks , choice of bidirectional converter to get high efficiency, combining ultra-capacitor with battery to increase the battery life, traction motors’ role and their suitability for a specific application. Inclusion of solar cell in HEVs may be a fairly new concept and has been discussed intimately. Various MPPT techniques used for solar-driven HEVs also are discussed during this paper with their suitability.
