Abstract

The invention provides a battery pack and a vehicle. The battery pack includes a lower casing, an upper battery module, a lower battery module, a module fixing structure, a first pressing member and an upper casing. The upper layer battery module is arranged above the lower layer battery module; the module fixing structure is arranged on the lower casing, and the module fixing structure is used to clamp the lower layer battery module in the lower casing and fix the upper layer battery module in the battery pack; the first The pressing part is used for pressing and fixing the lower layer battery module in the lower casing; the upper casing cover is arranged on the lower casing and is connected with the lower casing. Therefore, through the cooperation of the lower casing, the upper battery module, the lower battery module, the module fixing structure, the first pressing member and the upper casing, the assembly process and structure of the battery pack can be simplified, and the assembly efficiency of the battery pack can be improved. The production cost of the battery pack can also be reduced, the internal space of the battery pack can also be saved, and the energy density of the battery pack can be improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, and in particular, to a battery pack and a vehicle having the battery pack. Background technique [0002] In the related art, the battery module in the existing battery pack is provided with an end plate and a side plate structure. The end plate and the side plate increase the weight of the battery module and occupy the space in the battery pack, which is not conducive to the lightness of the battery pack. Quantitative design and improvement of energy density. In addition, the structure of the battery pack is relatively complex, resulting in high production cost of the battery pack. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a battery pack to solve the problems of complex structure and low energy density of the battery pack. [0004] In order to achieve the above object, the technical scheme of the present invention is achieved in this wa...
