摘要

鉴于目前电动汽车电站缺乏对电池组的定期性能评估和安全预警，动力电池荷电状态(SOC)的估算对于电站的安全运行和延长电池寿命具有重要意义。本文对动力电池SOC监测系统进行了研究，设计了动力电池监测系统架构。提出了一种改进的扩展卡尔曼滤波方法来检测动力电池的荷电状态。在上位机上采用c#和MATLAB的混合编程，最后实现了监控系统的验证。

Development of SOC monitoring system for power packs in Battery Swap Station

In view of the lack of periodic performance evaluation and safety warning of battery packs in electric vehicle power station, the estimation of power battery state of charge (SOC) is of great significance for the safety of power station and the extension of battery life. In this paper, the power battery SOC monitoring system is studied, and the system architecture of power battery monitoring is designed. The improved extended Kalman filter is proposed to detect the SOC of power battery. The mixed programming of C # and MATLAB is used on the host computer, and finally the verification of the monitoring system is realized.
