The invention provides an electric appliance control method and device and an electric automobile, and relates to the technical field of electric automobile control. The electric appliance control method comprises the steps that when it is confirmed that charging of a storage battery breaks down, the current automobile speed is obtained; electric appliance limitation judgment is carried out according to the current vehicle speed, and a work judgment result of a target electric appliance is obtained; and controlling the working state of the target electric appliance according to the working judgment result. According to the scheme, when charging of the storage battery breaks down, the working state of the electric appliance can be limited, the power supply pressure of the storage battery is reduced, the safety of low-voltage power supply of the whole vehicle is guaranteed, and basic operation of the whole vehicle is maintained.

    本发明提供了一种用电器控制方法、装置及电动汽车,涉及电动汽车控制技术领域,所述用电器控制方法包括:在确认蓄电池充电发生故障时,获取当前车速;根据所述当前车速进行用电器限制判断,获取目标用电器的工作判断结果;根据所述工作判断结果,控制所述目标用电器的工作状态。本发明的方案在蓄电池充电发生故障时,可限制用电器的工作状态,降低蓄电池的供电压力,保证整车低压供电的安全性,以维持整车的基本运行。
