Battery device and electric device

Abstract

The battery device comprises a first box body, a second box body and a battery monomer assembly, the first box body comprises a heat exchange plate, the heat exchange plate comprises a bottom plate and a first connecting plate, the interior of the bottom plate is of a hollow structure, and an open hole is formed in the side, facing the first connecting plate, of the bottom plate; the first connecting plate is arranged on one side of the hole in the bottom plate to form a module beam, and the hole is communicated with the outside through the first connecting plate; the battery monomer assembly is in heat conduction connection with the bottom plate, and the battery monomer assembly is connected to the module beam. According to the scheme provided by the invention, the first connecting plate not only can enable the opening in the bottom plate to communicate with the outside, but also can be used as a module beam to improve the strength of the first box body, so that the first connecting plate integrates the functions of the module beam and the runner, and the whole device does not need to be independently provided with the module beam; the number of parts is reduced while the requirement for the assembly space is reduced, and the effects of meeting the assembly requirement, reducing procedures and lowering cost are achieved.
