The application provides an end cover device and an energy storage device. The end cover device comprises a bracket and a roller shutter. The bracket has a socket, a receiving cavity and a sliding groove. The socket is configured to expose a connector of the energy storage device. The socket is in communication with the receiving cavity. The sliding groove is in the form of a curved groove section in the receiving cavity. The roller shutter is in the form of a straight groove section in the socket. The roller shutter is arranged on the bracket and is configured to slide along the sliding groove. When the connector is not used, the roller shutter is slid to the straight groove section, and the roller shutter at least partially covers the socket. When the connector needs to be used, the roller shutter is in the curved groove section, the roller shutter is curvedly received in the receiving cavity, and the socket is avoided. The curved roller shutter can reduce the occupied space. Compared with a rigid translation structure, the roller shutter can leave more space through the curling, so that the internal structure of the energy storage device is more compact. Compared with a flip structure, the roller shutter can save the reserved space in front of the connector through the sliding. Even in a narrow scene, the roller shutter can successfully cover and expose the connector.
