This method is suitable for modules with low energy density and small size. Large modules have a large number of cells and a longer length. Usually, a fixing plate is arranged in the middle of the cells to provide additional support and connection points to improve the overall structural strength of the cells after they are grouped. The module will not be deformed due to its too large length during transportation and installation. Therefore, the existing module fixture cannot satisfy the group work of a large module with a fixed plate in the middle.
