Battery device, electric device, energy storage device, energy storage system, and charging network

Abstract

The present application relates to a battery device, an electric device, an energy storage device, an energy storage system, and a charging network. The battery device comprises: a housing provided with an accommodating cavity; a battery cell provided in the accommodating cavity, wherein an explosion-proof valve is provided on a first wall of the battery cell; a heat exchange plate provided in the accommodating cavity and located between the first wall and a cavity wall of the accommodating cavity, the heat exchange plate being provided with a first pressure relief port corresponding to the explosion-proof valve; and an isolation plate provided between the first wall and the heat exchange plate, at least part of the isolation plate being located in the first pressure relief port, and the part located in the first pressure relief port being provided with a second pressure relief port corresponding to the explosion-proof valve. In the present application, the first pressure relief port is mated with the second pressure relief port to implement smooth spraying of the explosion-proof valve, and the part of the isolation plate located in the first pressure relief port can also block a sprayed high-temperature medium, so that the probability that the high-temperature medium is sprayed onto the heat exchange plate or other structures in the battery device is reduced, thereby protecting the overall structure of the battery device.
