摘要
以HX_N6混合动力机车为载体,电池管理系统为研究对象,从方案设计、实际应用情况、特殊环境下的SOC(剩余电池电量)算法研究出发,提出了一种基于充电状态下动态校准SOC策略。在宽电流范围采集精度不准的情况下,解决了SOC估算偏差过大问题,具有良好的工程应用前景。
The battery management system of the HX_N6 hybrid diesel locomotive was researched.From the plan design,practical application and the special circumstances of the SOC（remaining battery power） algorithm,a dynamic SOC calibration strategy based on charge stating was proposed.Under the condition of inaccurate acquisition accuracy in wide current range,the problem of too large estimation bias of SOC was solved,which had good engineering application prospect.
