An electrical vehicle environment was established to promote research and technology development in the area of high power energy management. The project incorporates a topology that permits parallel development of an alternative energy delivery system and an energy storage system. The objective of the project is to develop technologies, specifically power electronics, energy storage electronics and controls that provide efficient and effective energy management between electrically powered devices in alternative energy vehicles--plug-in electric vehicles, hybrid vehicles, range extended vehicles, and hydrogen-based fuel cell vehicles. In order to meet the project objectives, the Vehicle Energy Management System (VEMS) was defined and subsystem requirements were obtained. Afterwards, power electronics, energy storage electronics and controls were designed. Finally, these subsystems were built, tested individually, and integrated into an electric vehicle system to evaluate and optimize the subsystems performance.

Motor operates as the power source of the vehicles,which is one of the most important parts in the vehicle system.This paper is going to find out the speed control method of the DC motor of Golf electrical cars from both theory and practice.A virtual instrument,which produces the Pulse Width Modulation (PWM) signal,is developed with LabVIEW to control the motor speed.This smart motor speed controller differs from the traditional mechanical control of DC motor in daily life,and is instructive and significant as a new speed control method of vehicle motor.
