The invention provides a charging control method, device and equipment for a charging pile and a medium, and the method comprises the steps: controlling the first live wire and the zero wire of a power input end of the charging pile to be conducted when it is detected that the first live wire and the zero wire of a power grid connected with the charging pile are in a normal state, and the second live wire and/or the third live wire are/is in an open-phase state; and the second live wire and the third live wire are disconnected, so that the vehicle-mounted charger performs single-phase charging. With the adoption of the embodiment of the invention, when the charging pile detects that other phases except the L1 phase in the accessed power grid are open and the vehicle-mounted charger works in the single-phase charging state, the power transmission line between the other phases and the vehicle-mounted charger is actively disconnected, so that the phenomenon that the vehicle-mounted charger is damaged in the single-phase charging process can be avoided; therefore, the charging reliability of the vehicle-mounted charger is further improved, and the compatibility of the vehicle-mounted charger and a vehicle with a power grid is further improved.

    本发明提供了一种充电桩的充电控制方法、装置、设备及介质,所述方法包括:当检测到充电桩接入的电网的第一火线与零线处于正常状态,且第二火线和/或第三火线处于缺相状态时,控制充电桩的电力输入端的第一火线和零线导通,以及第二火线和第三火线断开,以使车载充电机进行单相充电。采用本发明实施例,能够在充电桩检测到接入的电网中除L1相以外的其他相缺相,而使车载充电机工作在单相充电状态下时,通过主动断开其他相与车载充电机之间的输电线路,以避免在车载充电机进行单相充电的过程中,出现因其他相的突然导通而导致的故障现象发生,从而进一步提高车载充电机的充电可靠性,以及车载充电机和车辆对电网的兼容性。
