In order to overcome the problem of the corrosion resistance of existing battery pack bottom protection plates being insufficient due to a surface PVC layer peeling under impact, the present application provides a battery protection bottom plate, comprising a protection layer, a metal plate and a fiber-reinforced resin layer. The metal plate is located between the protection layer and the fiber-reinforced resin layer, and the metal plate and the fiber-reinforced resin layer satisfy the condition in formula I. 0.4≤d1d2*e−ε0∗σ2σ0∗ε2+0.5≤2.0In addition, further disclosed in the present application are a battery pack composite protection structure comprising the battery protection bottom plate, and a vehicle.
