Abstract
The embodiment of the application discloses a battery device and an electric device, which comprise a box body and a first connecting bushing. The box body contains a battery monomer. The box body is provided with a mounting beam for mounting the battery device. The mounting beam comprises a first mounting surface. The first mounting surface is provided with a first through hole. The first connecting bushing is arranged on the first mounting surface and connected with the first mounting surface. The first connecting bushing comprises a second through hole. The second through hole is arranged in correspondence with the first through hole to pass through a fastener. The surface of the first connecting bushing towards the first mounting surface is a first surface. The edge of the first surface is provided with a first recess. The side wall of the first recess is provided with a second recess to make a sealing element away from a welding spot, so that the reliability of the battery device can be improved.
