Abstract

The invention relates to the technical field of energy storage equipment. The invention provides a battery pack and a vehicle. The battery pack comprises: a box body and a plurality of battery modules, the plurality of battery modules are arranged in the box body and are arranged in the horizontal direction, the battery module comprises a plurality of battery cells electrically coupled to each other by a first busbar, the battery cell comprises a battery case and electrode terminals, each electrode terminal of a first battery module located at a first outermost side in a horizontal direction among the plurality of battery modules faces the second battery module, and each electrode terminal of a second battery module located at a second outermost side in the horizontal direction faces the first battery module. The battery pack provided by the invention can effectively avoid short circuit of the electrode terminals of the battery modules caused by inward collapse of the box body, and thesafety of the battery pack is improved.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a battery pack and a vehicle. Background technique [0002] Secondary batteries have the advantages of high energy density, long service life, energy saving and environmental protection, and are widely used in new energy vehicles. [0003] When in use, usually multiple battery cells are stacked and electrically connected to each other through bus bars to form a battery module, and then multiple battery modules are assembled in the box and electrically connected to each other through wires to form a battery pack. The battery pack and the new energy vehicle The drive motor is electrically connected. Because the car will inevitably have traffic accidents such as rollover and side impact during driving, these traffic accidents may cause the side of the battery pack on the car to be compressed and deformed. The box of the battery pack is usually made of conductive m...
