Abstract

The invention relates to a cell grouping device for a quick-changing battery box of an electric car. The device comprises a cell grouping frame, a base and fixing pieces of the cell grouping frame and the base. The cell grouping frame is formed by connecting a horizontal component and a longitudinal component, so that the device can form a firm and stable mechanical structure. The surface of the device is filled with heat-radiating materials, so that the problem of non-uniform temperature in a cell grouping process is effectively managed and solved, the technical requirements on shock resistance and heat radiation can be met at the same time, and the cell grouping efficiency is improved.

Description

[0001] Technical field: [0002] The invention relates to a cell forming device, in particular to a battery cell forming device for a quick-change battery box of an electric vehicle. [0003] Background technique: [0004] The cell grouping device of the quick replacement battery box for electric vehicles refers to the equipment that provides power cell grouping technology for the quick replacement battery box. The equipment mainly includes the cell grouping frame, fixing parts and other components. The cell grouping device is an important part of the quick replacement battery box for electric vehicles, and the selection of the battery grouping device determines the design of the quick replacement battery box for electric vehicles. [0005] After long-term observation and research, it is found that the current cell grouping device cannot meet several requirements at the same time. Moreover, due to the non-standard design, it is not universal, making it difficult and expensive t...
