摘要
混合动力轿车锂离子电池组的管理中需要检测大量的电池单体电压.为降低对电池组单体电压的采样循环时间,增强管理系统数据采集的实时性,该文设计了一种基于分时并联采样方式的电池管理系统,它能够可靠地实现对动力电池运行时状态参数的监测,提高电池SOC的估算精度.
It is necessary to sample many single batteries＇ voltage when the Li - ion battery managed. To reduce the loop time of the single battery voltage sampling, and enhance the pack used in an HEV is BMS＇s real -time character, a concentrative structure battery management system was designed based on a new cell - voltage sampling method of time - sharing and parallel connection in accordance to the use of driven Li - ion batteries on HEV. The BMS achieves to detect the battery＇s states, and enhances the precision of battery SOC estimation.
