A battery protection bottom plate includes a protective layer, a metal plate, and a fiber-reinforced resin layer. The metal plate is located between the protective layer and the fiber-reinforced resin layer, and the metal plate and the fiber-reinforced resin layer satisfies:0.4≤d1d2*e-ε0*σ2σ0*ε2+0.5≤2.where d1 is a thickness of the fiber-reinforced resin layer in mm, d2 is a thickness of the metal plate in mm, ε2 is an elongation at break of the metal plate, σ2 is a tensile strength of the metal plate in MPa, ε0 is an elongation at break of the fiber-reinforced resin layer, and σ0 is a tensile strength of the fiber-reinforced resin layer in MPa.
