Abstract: The present disclosure relates to a casing for a battery pack and a battery pack. The casing has a receiving space and an opening in communication with the receiving space, the receiving space is formed by a wall portion of the casing, and the wall portion is formed from two or more stacked base plates, between which a plurality of cavities are formed. By forming a plurality of cavities in the wall portion, the casing for a battery pack provided by the present disclosure not only can improve the bearing capacity and the impact resistance of the casing, but also can achieve a thermal management of the battery assembly by filling the plurality of cavities with a phase change material or cooling liquid, which can further improve the mechanical property of the casing with a relatively light weight and relatively high reliability.

Abstract: The present disclosure provides a lower box body, a battery box and a vehicle, the lower box body comprises a base body, a first protecting assembly, a mounting hole. The base body comprises a bottom plate portion, a side plate portion, eave portions. The first protecting assembly is provided at outside of the base body, fixed to the base body and is attached to the eave portion. The mounting hole penetrates the eave portion and the first protecting assembly. The first protecting assembly improves the entirety structural strength of the lower box. Because the mounting hole is formed by penetrating the eave portion and the first protecting assembly, the structural stability of the mounting location of the lower box body is improved, thereby making the mounting location of the lower box body not be prone to be deformed or damaged when the battery box is subjected to the external force.
