Battery device and electric device

Abstract

A battery device (10) and an electric device. The battery device (10) comprises a case (11), battery cells (30) and a protective plate (20), wherein the battery cells (30) are accommodated within the case (11), and the protective plate (20) is connected to the case (11). The protective plate (20) comprises a first fiber resin layer (21) and a reinforcing plate (22), wherein the first fiber resin layer (21) is arranged on at least one side of the reinforcing plate (22) in the direction of thickness; the elongation after fracture e1 of the reinforcing plate (22) is ≥28％, and the strain hardening exponent N of the reinforcing plate (22) is ≥0.25. The provided battery device (10) helps reduce the risk of deformation of the protective plate (20), and also helps reduce the risk of fracture of the protective plate (20).
