The invention relates to a fast charging relay technology, and discloses a relay fast charging safety protection method, a charging control system, equipment and a medium, the method is applied to the charging control system controlled by at least one fast charging relay, and the method comprises the following steps: carrying out adhesion failure detection according to voltages at two ends of the fast charging relay; when it is detected that the fast charging relay is adhered, direct current charging is forbidden, and state detection is carried out on a charging protection inner cover plate; and when it is detected that the charging protection inner cover plate is in an open state, a main relay in a charging loop is disconnected, so that the charging port is prevented from being in a charged state. The safety of automobile charging can be improved based on relay control.

    本发明涉及快充继电器技术,揭露了一种继电器快充安全防护方法、充电控制系统、设备及介质,所述方法应用于通过至少一个快充继电器控制的充电控制系统,包括:根据所述快充继电器的两端的电压进行粘连失效检测;在检测到所述快充继电器发生粘连时,禁止直流充电,并对充电保护内盖板进行状态检测;在检测到所述充电保护内盖板处于打开状态时,断开充电回路中的主继电器,以避免充电口处于带电状态。本发明可以基于继电器控制提高汽车充电的安全性。
