Abstract

The present disclosure relates to an electric vehicle, at least one accommodating device (200) is formed on the electric vehicle, a plurality of single cells (100) are arranged in the accommodating device (200), and each single cell (100) includes an opposite At the first end and the second end, the accommodating device (200) includes a first frame (201) and a second frame (202) oppositely arranged along the first direction (A1), and a plurality of single cells (100) are arranged on the first frame (201) and the second frame (202). Between the frame (201) and the second frame (202), the length of the single cell along the first direction (A1) is L1, and between the first frame (201) and the second frame (202) along the first direction (A1) ) is L2, where L1 / L2 ≥ 50%. Since only one single battery is arranged in the first direction, the single battery itself can play the role of a beam and / or a longitudinal beam, thereby improving the space utilization rate of the accommodating device and improving the battery life of the electric vehicle.

Description

Technical field [0001] The present disclosure relates to the technical field of powered electric vehicles, and in particular, to an electric vehicle. Background technique [0002] In the prior art, the power battery pack mainly includes a containing device and a plurality of battery modules installed in the containing device. The battery module is mainly assembled from a plurality of single cells. The containing device usually includes a bottom plate and a side beam. The beams are arranged around the bottom plate. In order to make the accommodating device have sufficient strength and facilitate the installation of the battery module, a plurality of transverse beams and longitudinal beams are usually arranged between the side beams, and the plurality of transverse beams, longitudinal beams and the side beams and the bottom plate jointly define a plurality of There are multiple accommodating spaces for battery modules, and each battery module is arranged in a corresponding accommo...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the existence of beams and longitudinal beams, the volume utilization rate of the storage device is low, about 40%, and the number of single batteries that can be installed is limited, which cannot effectively improve the battery life of the power battery pack;

[0005] 2. The traditional power battery pack contains many battery modules. During the assembly process, each battery module needs to be fixed to the beam, and a large number of screws and other fasteners are required to fasten the modules. At the same time The beam or stringer has a certain weight, resulting in an increase in the weight of the containment device;

[0006] 3. Beams and longitudinal beams are arranged in the containment device, and the structure is complex, which increases the complexity of the manufacturing process of the containment device;

[0007] 4. The single battery needs to be assembled into a battery module and then placed in the storage device. The operation steps are complicated
