Abstract
A battery protection plate, a battery pack, and a vehicle are provided. The battery protection plate includes a base layer and an energy-absorbing layer. The energy-absorbing layer is arranged on a side of the base layer. A tensile strength and an elastic modulus of the base layer are greater than a tensile strength and an elastic modulus of the energy-absorbing layer, and an elongation at break of the energy-absorbing layer is greater than an elongation at break of the base layer.
