END COVER ASSEMBLY, ENERGY STORAGE APPARATUS, AND ELECTRICITY-CONSUMPTION DEVICE

An end cover assembly, an energy storage apparatus, and an electricity-consumption device are provided in the disclosure. The end cover assembly includes a top cover, a lower plastic member, a sealing member, and a terminal post. The lower plastic member is fixed to the top cover and defines a hollow hole and a first flow passage. The hollow hole extends through the lower plastic member in a direction from the lower plastic member to the top cover. One end of the first flow passage is in communication with a side wall of the hollow hole, and another end of the first flow passage is in communication with an outside. The sealing member includes a first sealing portion disposed in the hollow hole. The terminal post has a flange portion. The flange portion is disposed on one side of the first sealing portion facing away from the top cover and covers the first sealing portion. The flange portion and the top cover cooperatively compress the first sealing portion. The flange portion is insulated and separated from the top cover by the lower plastic member.
