BATTERY PACK AND VEHICLE

This application provides a battery pack and a vehicle. The battery pack includes: a battery accommodation box (10), including a box body (11) and a cover body (13), where the box body (11) fits with the cover body (13) to form an accommodation space; a partition beam, disposed in the accommodation space to partition the accommodation space into a plurality of accommodation units (V), where the partition beam includes a hitch beam (20) that extends in a first direction (X) parallel to a bottom wall (111) of the box body (11), a bottom of the hitch beam (20) is fixed to the bottom wall (111) of the box body (11), and a top of the hitch beam (20) is connected to the cover body (13); and a plurality of battery modules, where the battery modules include a plurality of battery cells (40), and each battery module is disposed in a corresponding accommodation unit (V). In the third direction (Z) perpendicular to the bottom wall (111) of the box body (11), the top of the hitch beam (20) is higher than a top of the battery cells (40). When the battery pack and the vehicle are impacted by an external force, the hitch beam (20) can fully surround and protect the battery cells (40), thereby helping to prevent all or part of the battery cells (40) from being directly impacted by the external force, and helping to improve safety performance of the battery pack.
