Hybrid Electric Vehicle Power Train Configuration with Battery Management System

Abstract

An HEV gives a different operating modes in a cycle which is a complete cycle and the operating modes are as follows: it gives the recharging of battery in a situation where acceleration happens and also in continuous braking and also it brings accelerating and cruising kind of operating modes. In the subsystem of electrical system there consists of main four parts they are like electric generator, motor and the batteries and DC-DC converter. The modelling of power split system model is given by planetary subsystem. The transmission of the mechanical motive force is done by the planetary system to system which done by combining and allocating the motors, engine and generators. 57 kilo watts with 670 rotation per minute of gasoline fuel engine is given by the Internal combustion engine by speed governor. The vehicles mechanical parts are given by the vehicle dynamics. The reference signal from the energy management system provides the signal for the drives such as motor drive, generater drive and for the internal combustion engine which makes the accurate power distribution from all these kind of different sources where it can use both the fuel energy and also can switch between electric motors where if there is no fuel situation or something and there will be a switching over to the electric drive by the internal combustion engine.
