Intelligent Test System on the Power Battery of Hybrid Electric Vehicle

The management system of battery plays an important role in prolong the service time of battery, improve the vehicle driving dynamic economy, reduce the using cost of hybrid electric vehicles and guarantee the safe, reliable operation. This article introduce a system of simulation and experience of based on ABIN company's computer hardware platform and software package. The system using distributed two levels control structure, upper computer is strong process PC, hypogenous computer has microprocessor, logic circuit control unit MC and channel measure unit constitute separate measure control system, PC-MC using 485 bus connect, MC can connect to several channels unit, every channel can measure the voltage and current separate. The additional temperature control component, temperature sensor, measure component and measure unit are make up battery management system's hardware system. The test system can simulate hybrid electric vehicle battery management system and complete dynamic test and battery experiment by program, so as to evaluate the performance of the power battery and battery management of hybrid electric vehicle provides an effective way.

I. Introduction

Hybrid Electric Vehicle conquered the disadvantage that simplex electric vehicle has, such as short continued drive mileage, long acceleration time. etc. it can be greatly decreased fuel consumption and emission of pollutants. Energy management system is the key technology of hybrid electric vehicle; it has function of managed, monitored and recovered the energy of hybrid electric vehicle which used in release, storage, distribution and baking time. Considering the cost factor, the capacity and volume of the battery impossible too large, after determined the dynamic system, how to effective and reasonable to exert the function of the dynamic battery. It plays an important role in prolong the service time of battery, improve the vehicle driving dynamic economy, reduce the using cost of hybrid electric vehicles and guarantee the safe, reliable operation.
