The invention relates to the technical field of automobiles, in particular to a control device and a control method for quiescent current of a whole automobile, a power supply loop and the automobile. The control device for the quiescent current of the whole vehicle comprises a main control module; the grid electrode of the MOS tube is connected with the main control module, the source electrode of the MOS tube is used for being connected with the positive electrode of a storage battery of the whole vehicle, the drain electrode of the MOS tube is used for being connected with a low-voltage load of the whole vehicle, the voltage detection module is connected with the main control module, and the voltage detection module is used for detecting voltages at the two ends of the storage battery; wherein the main control module is used for controlling the MOS tube according to the voltage at the two ends of the storage battery, so that the storage battery is connected with or disconnected from the low-voltage load of the whole vehicle. Therefore, under the condition that the vehicle is parked for a long time, the power supply circuit of the storage battery and the low-voltage load of the whole vehicle can be disconnected through the control device, so that the power consumption of the storage battery is reduced, and the requirement of a long-distance transportation scene is met.

    本发明涉及汽车技术领域,具体涉及一种用于整车静态电流的控制装置、控制方法、电源回路和车辆。用于整车静态电流的控制装置包括:主控模块;MOS管,MOS管的栅极与主控模块相连接,MOS管的源极用于与整车的蓄电池的正极相连接,MOS管的漏极用于与整车的低压负载相连接,电压检测模块,与主控模块相连接,电压检测模块用于检测蓄电池的两端电压;其中,主控模块用于根据蓄电池的两端电压,控制MOS管,以使得蓄电池与整车低压负载接通或断开。这样,在车辆处于长时间停放的情况下,可以通过控制装置实现对蓄电池与整车低压负载的供电电路断开,进而降低蓄电池的电量消耗,以满足长距离运输场景需求。
