Abstract

A battery pack casing, a battery pack using the battery pack casing, and a vehicle with the battery pack are provided. The battery pack casing comprises a tray, a middle beam, a cover plate and a mounting member. The tray comprises a bottom plate and a plurality of side beams, which together form a receiving space for accommodating a battery unit, wherein the receiving space is open at one side, and the cover plate is configured to close the open side of the receiving space. The plurality of side beams comprise two first side beams arranged opposite to each other. The middle beam is located in the receiving space and two ends of the middle beam along a length direction are respectively spaced by a predetermined distance from or in contact with the two first side beams. The length of the middle beam is greater than a projection dimension of the battery unit along the length direction of the middle beam. The mounting member is configured to sequentially extend through and fasten the bottom plate, the middle beam and the cover plate, and also configured to be connected and fixed to the transverse beam of the vehicle body. The battery pack casing aims to improve the ability of the battery pack casing to withstand collisions from the side, which is beneficial to the decrease in the design strength of a transverse beam of a vehicle body.
