The invention relates to the technical field of charging management, and provides an AC charging pile relay protection control method, a charging pile and a storage medium. The control method comprises the steps that under the condition that it is monitored that the charging pile is switched from a charging state to a preparation state, a main relay of the charging pile is controlled to be cut off, and under the condition that a charging gun is not pulled out of a target vehicle, waiting time is started to be calculated; and when it is monitored that the working state of the charging pile is switched from the preparation state to the charging state and the waiting duration which does not reach the first duration threshold exists, the main relay is not controlled to be closed. By adopting the technical scheme, whether the main relay is controlled to be closed or not can be determined on the basis of whether the duration of switching the charging pile from the charging state to the preparation state last time reaches the first duration threshold value or not under the condition that the working state of the charging pile is monitored to be switched from the preparation state to the charging state; in this way, frequent switching-off and switching-on of the main relay can be avoided, and then relay damage to the charging pile can be avoided.

    本申请涉及充电管理技术领域,提供了交流充电桩继电器保护控制方法、充电桩及存储介质。控制方法包括:在监测到充电桩从充电状态切换至预备状态的情况下,控制充电桩的主继电器切断,并在充电枪未从目标车辆拔出的情况下,开始计算等待时长;在监测到充电桩的工作状态从预备状态切换至充电状态且存在未达到第一时长阈值的等待时长的情况下,不控制主继电器闭合。通过采用上述技术上方案,可以在监测到充电桩的工作状态从预备状态切换至充电状态的情况下,基于距离充电桩上一次从充电状态切换为预备状态的时长是否达到第一时长阈值来确定是否控制主继电器闭合,如此可以避免主继电器频繁的切断和闭合,进而可以有助于避免充电桩发生继电器损坏。
