The invention relates to the technical field of power supply power consumption control, in particular to a vehicle low-voltage power consumption control method and device, a vehicle and a storage medium, and the control method comprises the steps that in response to the fact that a vehicle is powered on and enters an external discharging state, a VCU controls a DC/DC and a DC/AC to work, a vehicle low-voltage load and a storage battery are charged through the DC/DC, and external discharging of the vehicle is achieved through the DC/AC; the storage battery voltage and the DC/DC output current are obtained, if the storage battery voltage is smaller than or equal to an undervoltage threshold value or the DC/DC output current is larger than or equal to a short circuit overcurrent threshold value, the VCU controls the DC/AC to be closed, and the DC/DC maintains low-voltage output and executes load throwing according to a preset strategy. The power supply of the low-voltage load of the whole vehicle can be ensured, and the feed of the storage battery is avoided.

    本发明涉及电源功耗控制技术领域,具体涉及一种整车低压功耗控制方法、装置、车辆及存储介质,所述控制方法包括:响应于整车上电且进入对外放电状态,VCU控制DC/DC和DC/AC工作,通过所述DC/DC供给整车低压负载和蓄电池充电,通过所述DC/AC实现整车对外放电;获取蓄电池电压和DC/DC输出电流,若蓄电池电压≤欠压阈值或DC/DC输出电流≥短路过流阈值时,VCU控制DC/AC关闭,DC/DC维持低压输出且按预设策略执行抛负载。其能够保证整车低压负载的功率供给,避免蓄电池馈电。
