摘　　要：分析了电动汽车领域电池组在使用过程中出现的问题,以及要求快速充电的特点。在目前国内外电池管理系统的发展基础上,提出了基于分只同时均充理念的电池管理系统。以AT89C51单片机为控制模块核心,利用压频转换器LM331、温度传感器DS18B20分别采集电压和温度参数,进行电压温度补偿,实现了对电池充电的电压控制,并具有一定的控制精度。The problems during the charging process of electric vehicle battery group and fast charging characteristics were analyzed. On the basis of domestic and overseas developing status of battery management system, a kind of battery management system based on the conception of charging single cell in the same time was proposed. Taking the AT89C51 as the core of control module, collecting voltage, temperature parameter by the V/F conversion machine-LM331 and DS18B20 respectively, and carrying on voltage with the compensation of temperature, the voltage control was achieved and the precision of control was gotten in the charging process.
