The invention discloses a charging control circuit, a battery pack and an electric device. The charging control circuit comprises a negative voltage isolation module, a charging switch module and a discharge module. The first end of the negative voltage isolation module is connected with a charging signal. The negative voltage isolation module is used for isolating negative voltage generated by the charger; the control end of the charging switch module is connected with the second end of the negative voltage isolation module, the first end of the charging switch module is connected with the energy storage module, and the second end of the charging switch module is connected with the charger; the charging switch module is used for controlling whether a charging loop of the energy storage module is conducted or not; the first end and the second end of the discharge module are connected with the control end of the charging switch module, and the third end of the discharge module is connected with the second end of the charging switch module; and the discharge module is used for releasing charges stored in the charging switch module so as to turn off the charging switch module. According to the charging control circuit provided by the embodiment of the invention, the influence of negative voltage generated by the charger on the charging switch module is avoided, and the charging reliability and safety are improved.
