Battery pack and vehicle

The utility model discloses a battery pack and a vehicle, the battery pack comprises a box body and a battery module, an installation space is formed in the box body, an installation beam is arranged in the installation space, the battery module is arranged in the installation space, and a fixed end plate of the battery module is fixedly arranged on the installation beam; and the supporting block is arranged in the mounting space and connected with the inner side wall of the mounting space, and the supporting block and the fixed end plate are oppositely arranged. Therefore, by arranging the supporting blocks, when the battery pack is laterally extruded, the supporting blocks are in contact with the fixed end plates to apply extrusion force to the fixed end plates, and the fixed end plates transmit the extrusion force to the mounting beams, so that the supporting range of the mounting beams is expanded, the lateral supporting strength of the box body is improved, and the risk that the battery cells of the batt
