Description

Technical Field

[0001] The present invention relates to the field of hoisting tools for battery modules, and particularly to a hoisting tool for long battery modules. Background Art

[0002] Currently, in the rapid development of new energy vehicles, new energy vehicle models are constantly being developed, passenger vehicles are becoming increasingly mature, and commercial vehicles are also being continuously promoted and implemented. However, for the whole vehicle, higher requirements are put forward for the energy density of the battery system. There are two ways to improve the battery energy density: one is to increase the specific energy of a single cell; the other is to lighten the structure of the battery pack. Increasing the specific energy of a single cell is technically difficult, has a long R & D cycle, and requires a large amount of capital investment. In contrast, it is easier to lighten the structure of the battery pack.

[0003] The lightening of the module shows a trend of large modules, not only reducing the weight of the module end plate, but also releasing the space size. However, long modules and large modules also face structural problems, such as hoisting problems during the production and assembly process, long modules with poor rigidity, and easy deformation during hoisting. Under the current development requirements, increasing the length is inevitable. Only by solving the problem of the hoisting tool for the module can the production feasibility of large modules and long modules be met. Therefore, in order to meet the adaptability of the shelling tool, higher requirements are put forward for the structural design of the tool.
