The utility model relates to the technical field of batteries, and particularly discloses an insulating cap, a battery module, an energy storage plug-in box and an energy storage system. The insulating cap comprises a top plate and a side plate, the top plate comprises a top plate body and a sleeve, the sleeve is arranged on the top plate body, and a positioning groove is formed in the sleeve and can be clamped and matched with the bolt head. The side plates are arranged on the periphery of the top plate body in a surrounding mode to form the side wall of the insulation cover cap. And the top plate covers the connection position of the output tab and the output copper bar of the battery module, so that the connection position is prevented from being exposed outside, and the insulating property of the connection position is improved. Through clamping cooperation of the positioning groove in the sleeve and the bolt head at the connection position, rapid installation of the insulation cap is realized. The insula
