The invention discloses an emergency starting system of a vehicle, the vehicle and a control method of the vehicle. The input end of the power distribution unit is connected with the M series battery cells of the power battery, the output end of the power distribution unit is connected with a battery management system of the power battery, and the sum of the voltages of the M series battery cells is matched with the working voltage of vehicle-mounted electric equipment of the vehicle; the low-voltage input end of the DC/DC converter is connected with the output end of the power distribution unit; when the vehicle is ignited and started, the power distribution unit is conducted, so that the M series-connected battery cells provide a starting power source for the DC/DC converter and the battery management system, and the battery management system and the DC/DC converter are started. The technical problem that the success rate of vehicle emergency starting is low is solved.
本发明公开了一种车辆的应急启动系统、车辆及其控制方法,该系统包括:动力电池;配电单元,配电单元的输入端与动力电池的M个串联电芯连接,配电单元的输出端与动力电池的电池管理系统连接,M个串联电芯的电压之和与车辆的车载用电设备的工作电压匹配;DC/DC转换器,DC/DC转换器的低压输入端与配电单元的输出端连接;其中,在车辆点火启动时,导通配电单元,以使M个串联电芯向DC/DC转换器和电池管理系统提供启动电源,以启动电池管理系统和DC/DC转换器。通过本发明解决了车辆应急启动的成功率低的技术问题。
