    摘要： The present invention discloses a battery pack and a vehicle. The battery pack includes: a battery core; a tray bottom plate (10), where the tray bottom plate (10) has a pressed area (112), and the pressed area (112) has an electrode core pressing area; and a side beam (23), having a side beam body with a supporting portion (22). In a first direction of the side beam (23), an orthographic projection of the supporting portion (22) and an orthographic projection of the electrode core pressing area have an overlapping area. In a second direction of the side beam (23), the orthographic projection of the supporting portion (22) and the orthographic projection of the electrode core pressing area have an overlapping length of M1, and M1 meets the relation formula: 9 mm ≤ M1.
