The invention provides a V2L overcurrent prevention method and device for an electric vehicle battery. The method comprises the steps that in response to starting of a V2L mode, direct current output by a battery is converted into low-frequency alternating current lower than a preset frequency through an inverter, and the low-frequency alternating current is output; and in response to detecting that the electric appliance is connected to the alternating current, gradually increasing the frequency of the output alternating current to the working frequency of the electric appliance.

    本申请提供一种电动汽车电池的V2L防过流方法和装置。其中,所述方法包括:响应于启动V2L模式,通过逆变器将电池输出的直流电转化成低于预设频率的低频率的交流电进行输出;响应于检测到用电器连接到所述交流电,逐渐提升输出的所述交流电的频率至用电器工作频率。
