The embodiment of the invention provides a charging and discharging method and device of a charging pile, a storage medium and the charging pile. The method comprises the steps of supplying power to a power grid in a discharge mode if it is detected that the voltage of the power grid is smaller than a first set threshold or reaches first set time; and if it is detected that the power grid voltage is larger than a second set threshold value or reaches second set time, the electric vehicle is charged in the charging mode. According to the technical scheme provided by the embodiment of the invention, the V2L function of the electric vehicle and the V2G mode of the household AC charging pile can be utilized to realize energy exchange between the electric vehicle and the power grid, the operation cost of the charging pile can be reduced, and the utilization rate of electric quantity can be improved.

    本发明实施例提供了一种充电桩的充放电方法、装置、存储介质和充电桩。该方法包括:若检测到电网电压小于第一设定阈值或达到第一设定时间,通过放电模式为电网供电;若检测到电网电压大于第二设定阈值或达到第二设定时间,通过充电模式为电动汽车充电。本发明实施例提供的技术方案中,能够利用电动车辆的V2L功能和家用交流充电桩的V2G模式,实现电动车辆与电网之间的能量交换,能够降低充电桩的运行成本并提高电量的利用率。
