Problems solved by technology

[0005] 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;
[0006] 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;
[0007] 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;
[0008] 4. The single battery needs to be assembled into a battery module and then placed in the storage device. The operation steps are complicated

Abstract

The disclosure relates to an electric vehicle, at least one accommodating device (200) is formed on the electric vehicle, the at least one accommodating device (200) is a cavity (300) formed on the electric vehicle, and a plurality of single batteries (100) are arranged in the accommodating device (200). The single batteries play a role of a cross beam and / or a longitudinal beam, the space utilization rate of the containing device is increased, and the cruising ability of the electric vehicle is improved.

Description

[0001] This application is a divisional application with the filing date of "2019-06-21", the application number of "201910544937.8", and the application name of "power battery pack, energy storage device and electric vehicle". technical field [0002] The present disclosure relates to the technical field of power electric vehicles, and in particular, relates to an electric vehicle. Background technique [0003] In the prior art, the power battery pack mainly includes a receiving device and a plurality of battery modules installed in the receiving device. The battery module is mainly assembled from a plurality of single cells. The beams are arranged around the base plate. In order to make the receiving device have sufficient strength and facilitate the installation of the battery module, a plurality of crossbeams and longitudinal beams are usually arranged between the side beams, and the plurality of crossbeams, longitudinal beams, side beams and the bottom plate together de...
