The battery pack composite includes a battery pack and a battery protection bottom plate. The battery protection bottom plate includes a metal plate and is disposed below the battery pack. A buffer zone is disposed between the battery pack and the battery protection bottom plate, and the buffer zone and the metal plate satisfying:0.018≤(d-0.4)⁢hσ*ε≤0.0⁢8⁢5,where d is a thickness in mm of the metal plate, σ is a tensile strength in MPa of the metal plate, ε is an elongation at break of the metal plate, and h is a height in mm of the buffer zone.
