摘要
在电动汽车动力电池组充放电过程中,必须通过电池管理系统对电池组总电压、充放电电流、工作温度、组内单体电池电压进行实时准确的监测,从而保证电池安全性,延长其使用寿命。本文搭建了基于LabVIEW的电池管理系统监测平台,实现了对电池多参数的实时采集、处理、显示、存储等功能,进而对电池的充放电过程进行有效控制,并为电池荷电状态(SOC)的估计算法的有效性测试提供硬件平台及软件接口。测试结果表明,该电池监测平台能够有效实现电池管理系统的监测,并具有一定的功能扩展性。
In the process of charging and discharging of electric vehicle battery pack, the real time and accurate moni- toring on the parameters like the total voltage of the battery pack, charge and discharge current, single cell voltage within the group and operating temperature of battery management system is needed, thus ensuring the battery securi- ty, and extending their useful life. This paper builds a battery management system monitoring platform based on Lab- VIEW, to achieve real-time acquisition of battery parameters, processing, display, storage and other functions, thus effectively control the battery charging and discharging process, and provide the estimation algorithm on battery state of charge(SOC) the test hardware platform and software interface. The test results show that the battery monitoring plat- form can effectively achieve the monitoring of the battery management system, and with certain extensions.
