基于Labview的锂离子电池组管理系统设计
|
摘要
在实际应用中,往往将单体电池串联或并联,组成锂离子电池组,来满足某一装置用电要求。串并联组合模式的电池组,在充放电时需要电压均衡管理。设计一款以STM32和LTC6803为核心的电池管理系统(BMS),该系统可根据SOC评估算法和均衡控制算法对电池组进行均衡保护,防止电池过充和过放,对采集的电池组数据进行处理并上传给上位机,上位机实时监测显示界面用LabVIEW软件编写。
In practical application, the single cell is usually connected in series or in parallel to form a lithium ion battery to meet the demand of a certain device. Voltage equalization management is required for series-parallelmode batteries during charging and discharging. A battery management system(BMS), based on STM32 and LTC6803 was designed. The system can protect the battery pack from overcharge and overdischarge according to the SOC evaluation algorithm and the equalization control algorithm. The collected battery pack data were processed and uploaded to the upper computer. The real time monitor and display interface of the upper computer was compiled by Labview software.
