Battery device and electric device

Abstract

Provided in the present application are a battery device and an electric device. The battery device comprises a case and a plurality of battery cells, wherein the case is provided with a connecting portion; the plurality of battery cells are accommodated in the case; each battery cell comprises a casing, an electrode assembly and an electrode terminal, wherein the casing comprises a first casing wall and a second casing wall opposite to each other in a first direction, the first casing wall supports the electrode assembly, the electrode terminal is arranged on the second casing wall and is electrically connected to the electrode assembly, and at least part of the connecting portion is located on the side of the second casing wall facing away from the first casing wall in the first direction; and the plurality of battery cells comprise at least one first battery cell, the second casing wall of the first battery cell comprises a first part and a second part, the second part protrudes from a surface of the first part facing away from the first casing wall, the electrode terminal is arranged on the first part, and the second part is connected to the connecting portion in the first direction. The stability of the first battery cell in the case can be improved, and the impact resistance and the vibration resistance of the battery device are improved, thereby improving the reliability of the battery device.
