The invention discloses a load loop of a vehicle distribution box, the vehicle distribution box and a control method. The vehicle distribution box comprises a load loop and a power supply end of the vehicle distribution box, the load loop of the vehicle distribution box comprises a controller, a main power supply output module, an auxiliary power supply output module, a pre-charging module and a voltage monitoring module, and the controller is connected with the main power supply output module, the auxiliary power supply output module, the pre-charging module and the voltage monitoring module. The main power output module, the auxiliary power output module and the pre-charging module are respectively connected with a power end and a load end, and the voltage monitoring module is connected with the load end. The pre-charging module supplies power to the load end firstly, the voltage monitoring module monitors the voltage of the load end in real time, and when the voltage of the load end reaches the threshold voltage, the main power output module is controlled to be started to supply power to the load end, so that the load end is prevented from bearing large current impact, and the service life of the load end is prolonged; and the production cost of the load loop of the vehicle distribution box is reduced.

    本申请公开了一种车辆配电盒的负载回路、车辆配电盒及控制方法。车辆配电盒包括车辆配电盒的负载回路和电源端,车辆配电盒的负载回路包括控制器、主电源输出模块、辅电源输出模块、预充模块和电压监测模块,控制器分别连接主电源输出模块、辅电源输出模块、预充模块和电压监测模块,主电源输出模块、辅电源输出模块和预充模块分别连接电源端和负载端,电压监测模块连接负载端。本申请采用预充模块先给负载端供电,并由电压监测模块实时监测负载端电压,在负载端电压达到阈值电压时,控制主电源输出模块开启,完成为负载端供电,避免了负载端承受大电流冲击,提升了负载端的使用寿命,降低了车辆配电盒的负载回路的生产成本。
