The invention provides a vehicle and a low-voltage storage battery charging system, and the system comprises an operational circuit which is used for collecting a first voltage outputted by a positiveelectrode output end of a low-voltage storage battery, and outputting an activation voltage to a control unit when the first voltage is lower than a preset low-voltage threshold value, so as to wakeup the control unit; and the control unit is used for sending an awakening message to the bus after being awakened so as to awaken the energy storage system. According to the charging system of the low-voltage storage battery, on the premise of charging the low-voltage storage battery, the number of parts and the number of wiring harnesses can be reduced, and the cost is reduced.

    本发明提出一种车辆和低压蓄电池的补电系统,其中,所述系统包括:运算电路,用于采集低压蓄电池正极输出端输出的第一电压,并在第一电压低于预设的低电压阈值时,输出激活电压至控制单元,以唤醒控制单元;控制单元,用于在被唤醒后,向总线发送唤醒报文,以唤醒储能系统。本发明的低压蓄电池的补电系统,能够在对低压蓄电池充电的前提下,减少部件数量和线束数量,降低成本。
