摘　　要：为了解决锂电池组串联充电每个电池单体个性差异的问题,采用并联充电方式,设计了一种基于LabVIEW的锂离子电池组充电管理系统。上位机程序使用图形化开发软件LabVIEW编写,完成人工设定充电参数,实时监测80块电池单体的电压、电流、电量、电池状态并进行相应数据的存储,发生故障时,及时进行报警并保存故障信息等功能。上下位机之间采用CAN总线以主从的方式进行通讯,运用队列的方式作为接收数据缓存区,解决了80块电池单体与上位机通信协调问题。对电池组进行充电实验,显示电池组状态信息,表明充电管理运行良好,可靠性强,具有较好的实际应用前景。To solve the problem of batteries＇ individual difference when they were charged in series,a new battery charging management system was designed based on LabVIEW,which allowed batteries to be charged in parallel.Host computer programs were written in LabVIEW.The system has functions of setting charging parameters,monitoring battery＇s voltage,current,power,status as well as storing corresponding data.When errors occurred,the system would alarm and save these errors.Host computer used CAN bus to communicate with controllers and queens as data cache to receive data.This method solved communication coordination problems.The battery packs charging experiment was conducted.LabVIEW interface showed charging results,which explained that the battery charging management system worked well.It is reliable and has a wide range of practical application.
