    Abstract: A battery tray (10), a battery pack, and an electric vehicle are provided. The battery tray (10) includes a tray body (100), a first protection plate (300), and a second protection plate (200). The first protection plate (300) includes an energy-absorbing plate (302) and high-strength plates (301) located on two sides of the energy-absorbing plate (302), and the energy-absorbing plate (302) is in a cellular structure. A wave impedance value of the second protection plate (200) is less than a wave impedance value of the high-strength plate.
