Abstract

The invention belongs to the technical field of vehicles, and discloses a battery pack and a vehicle. The battery pack comprises a battery shell; the battery shell is internally provided with a first battery module, a second battery module, first supports and a supporting rib assembly; the second battery module is arranged below the first battery module and is at least partially overlapped with the projection of the first battery module in the height direction; the first supports are arranged on the two sides of the first battery module in the length direction, and the first supports are connected to the first battery module and the second battery module correspondingly and can abut against the side face of the first battery module and the side face of the second battery module correspondingly; the supporting rib assembly is arranged in the first supports and used for restraining deformation of the first supports. The supporting rib assembly is arranged in the first supports, the strength and rigidity of the first supports are improved, the risk that the first supports deform is reduced, and thus the stability of the whole structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery pack and a vehicle. Background technique [0002] Since the energy density of the battery pack is directly related to the improvement of the mileage of the vehicle, most of the existing pure electric vehicles use a moduleless battery pack to increase the energy density of the battery pack to achieve the purpose of saving the cost of the battery pack. However, the battery module adopts a non-module setting method, which will expand in the length direction during subsequent processing and use. If there are no structural parts to resist the expansion force of the battery cell, the safety of the battery pack will be seriously affected. [0003] If the battery pack adopts a single-layer battery module, when electric vehicles and other electrical equipment have relatively high power requirements (for example, to increase battery life), the battery pack needs to make full use...
