The invention discloses a hybrid electric vehicle storage battery charging system and method, and the system comprises a storage battery electric quantity detection module EBS, a vehicle body controller BCM, a vehicle-mounted communication module T-BOX, a server, an engine controller ECM, a vehicle control unit HCM, a power battery controller BMS and a voltage converter DCDC. The whole vehicle controller HCM is connected with the vehicle body controller BCM, the voltage converter DCDC, the engine controller ECM, the vehicle-mounted communication module T-BOX and the power battery controller BMS; the vehicle control unit HCM is used for controlling on and off of the high-voltage system and judging whether an engine is started or not. The power battery controller BMS is connected with the voltage converter and the storage battery and used for converting the voltage of the power battery into the voltage capable of charging the storage battery. According to the invention, the intelligence of the charging process is improved, and the defects of the charging system in the prior art are overcome.

    本发明公开了一种混合动力汽车蓄电池补电系统及方法,系统包括蓄电池电量检测模块EBS、车身控制器BCM、车载通信模块T‑BOX、服务器、发动机控制器ECM、整车控制器HCM、动力电池控制器BMS以及电压转换器DCDC,所述整车控制器HCM与所述车身控制器BCM、电压转换器DCDC、发动机控制器ECM连接、车载通信模块T‑BOX、动力电池控制器BMS连接;所述整车控制器HCM用于控制高压系统的闭合和断开,并判断是否启动发动机。所述动力电池控制器BMS和所述电压转换器和所述蓄电池分别连接,用于将动力电池的电压转换为可以给蓄电池充电的电压。本发明提升了补电过程的智能性,完善了现有技术补电系统的缺陷。
