The invention discloses a storage battery charging control method and system. The method comprises the following steps of acquiring a current battery state fed back by a battery management system and battery actual measurement voltages at two ends of a storage battery, determining a target charging control logic based on the current state of the battery and the actually measured voltage of the battery, and based on the target charging control logic, controlling a power battery connected with the battery management system to work, adjusting the current state of the battery, and controlling a high-voltage relay arranged between the power battery and the storage battery to be closed or opened. According to the method and the system, switching of two working states of charging and non-charging of the power battery can be controlled based on the target charging control logic, so that frequent switching of the two working states is avoided, and the service life of the battery and the safety of the charging process are guaranteed; and the high-voltage relay is controlled to be switched on or off, so that the problem of failure of the high-voltage relay caused by frequent switching of the two working states is avoided, and the service life of the high-voltage relay is guaranteed.
