Abstract

The present application is applicable to the field of battery technologies, and provides a battery device (100), an energy storage device, and an electric device. The battery device includes: a box body (10); a battery cell (20), accommodated in the box body; and an electric control assembly (30), accommodated in the box body. The electric control assembly includes a bracket (31) and an electric control component. The bracket includes a bracket body (311). A side that is of the bracket body and that faces the battery cell is connected to a protruding structure (312), and a side that is of the bracket body and that is away from the battery cell is provided with the electric control component. The electric control assembly further includes a heat insulation plate (32) disposed on the side that is of the bracket body and that faces the battery cell. The heat insulation plate, the bracket body, and the protruding structure enclose to form a cavity. In the battery device provided in embodiments of the present application, the protruding structure is disposed on the side that is of the bracket body and that faces the battery cell, and the heat insulation plate, the protruding structure, and the bracket body enclose to form the cavity, so that the cavity and the heat insulation plate jointly function to hinder heat transfer and provide a heat insulation effect.
