COMPARATIVE STUDY OF SINGLE PHASE AND THREE PHASE REAL TIME SIMULATION OF EV BATTERY CHARGING SYSTEM

It is necessary that alternating sources for oil reserves that are exhaustible in future need to be found. Due to combustion of oil, it will create environmental pollution problem. Most of the vehicles now a day are dependent on internal combustion engine for their operation which is cause of worry because they are responsible for air pollution so, vehicle manufacturer now a day are looking for alternative sources that can reduce pollution. Due to arising problem of pollution plug in hybrid electric vehicles are veryessential for the future. The Hybrid electric vehicle consists of two propulsion sources that are an electrical motor and internal combustion engine. Electrical road vehicle derives all part of their energy from on board battery. On-board chargers are mounted with in the vehicles and designed to operate only on the vehicles. The Plug in Hybrid Electric Vehicles are driven by the energy stored in the battery. Through conductive AC charging method, Electric vehicle supply equipment is connected to Electric vehicle for charging the battery. Apart from charging it can also help in creating trustworthy equipment ground track and exchange control data among Electric vehicle and Electric vehicle supply equipment. This project discusses electrical interface between Electric vehicle and Electric vehicle supply equipment to facilitate conductive charging and design of an on-board charger for fast charging of the hybrid electric vehicle. The aim of this project is to design interfacing system between Electric vehicle and Electric vehicle supply equipment as per automotive industry standard and to design of 3.45 kw on-board charger using Matlab software. By modelling the charger, charging of Li-ion battery can be done which is used for providing propulsion torque and through various stages of charger voltage and current level is controlled and make them desired for charging. This project shows how one can design conductive charging system as per automotive industry Standards.
