Technology and Key Strategy of IE4 Permanent Magnet Brushless DC Motor Drive for Electric Vehicle Application

Abstract

Environmental protection and energy conservations are the main concern of 21st century Asia Pacific developing countries. This concern has compelled to design and develop zero pollution road transportation Electric Vehicles (EVs). The EV system consist of energy storage devices such as battery, fuel cell, ultra-capacitors along with electric propulsion, body of the vehicle and energy management system with the diversified technology of electrical, electronics, mechanical, automotive and chemical engineering. The objective of electric vehicle is to produce commercial viable range, efficient performance, and comfort with safety and reliable operations at cheaper price than its counterpart the Internal Combustion Engine Vehicle (ICEV). The PMBLDC motors are the present choice of automobile industries and researchers because of its high power density, compact size, reliability, with noise free and minimum maintenance requirements. The present state of art Permanent Magnet Brushless DC (PMBLDC) Motor drive for the electric vehicle application is studied / reviewed in this paper.. In addition the study also reveals the advancement of the Power Processing Unit (PPU) which consists of Microelectronics and Controls (Me and C) to produce the super-premium efficiency PMBLDC drive system for EV applications.
