The invention discloses a self-heating system and method for a power battery of a hydrogen energy fuel cell automobile. The system comprises a vehicle control unit VCU, a vehicle-mounted T-BOX, a battery management system BMS, a trip computer ECU1, a fuel cell controller FCU and a mobile phone APP. The vehicle control unit VCU, the vehicle-mounted T-BOX, the battery management system BMS and the trip computer ECU1 are connected and communicate through a CAN bus. The vehicle-mounted T-BOX and the mobile phone APP communicate with the service provider TSP through a wireless network. The method specifically comprises the steps that a service provider TSP obtains the local temperature in real time in the power-off parking period, and when the environment temperature of the geographic position where a vehicle is located is lower than a set threshold value A, the service provider TSP sends a vehicle using reminding plan to a mobile phone APP through a wireless network; the mobile phone APP feeds back whether the vehicle is used or not, and if the vehicle is fed back within the preset time T1, a power battery automatically enters a heating state; and otherwise, the service provider TSP sends the vehicle use reminding plan again after a certain period of time. The invention has the beneficial effects that the cost is low, and the heating energy consumption of the power battery can be saved.
本发明公开了一种氢能燃料电池汽车动力电池自加热系统及方法,系统包括:整车控制器VCU、车载T‑BOX、电池管理系统BMS、行车电脑ECU1、燃料电池控制器FCU和手机APP;其中,整车控制器VCU、车载T‑BOX、电池管理系统BMS、行车电脑ECU1通过CAN总线进行连接通讯;车载T‑BOX和手机APP通过无线网络与服务商TSP通信。方法具体为:所述服务商TSP在断电停车期间实时获取当地温度,当车辆所在地理位置环境温度低于设定的阈值A时,所述服务商TSP通过无线网络向手机APP发送提醒用车计划;手机APP反馈是否用车,若在预设时间T1内反馈用车,则动力电池自动进入加热状态;否则,服务商TSP间隔一定时间后再次发送提醒用车计划。本发明的有益效果是:成本低,可节约动力电池加热能耗。
