插入式混合动力电动汽车电池管理系统设计与试验研究

摘要

The battery management system of a PHEV was analyzed and designed .The SOC dynamic calculation ,signal pro-cessing ,charging process of BMS waking up and sleep mode ,and relay auxiliary contact monitor were studied and verified by the laboratory and vehicle test .The test results show that the designed SOC battery management system of PHEV features in accurate dynamic calculation ,reliable monitoring of insulation state ,reasonable charging process and high anti-interference abil-ity and can meet the requirement of vehicle design .%针对某款插入式混合动力电动汽车（PHEV）的电池管理系统进行了分析和研究，设计了适合PHEV的车用电池管理系统，对SOC动态估算、信号的处理方式、BM S的充电唤醒和退出流程以及继电器的辅助触点检测进行了研究，并进行了试验室和实车试验验证。试验结果表明，设计的PHEV电池管理系统SOC动态估算准确，绝缘状态检测可靠，充电启动和退出流程合理，满足车用设计要求，并且具有良好的抗干扰性。
