Problems solved by technology

The expansion force usually affects the service life of the battery cell and the battery module, and will cause the battery capacity of the electromagnetic module to decrease
[0003] In order to solve this problem, the current hard-shell battery modules usually reserve a certain gap between the cells to reserve expansion space for the cells, but the gap reserved between the cells can only be used in the initial stage of cell expansion. Function, when the cell continues to expand and two adjacent cells are in contact, it will not be able to continuously improve the expansion force
Moreover, the internal structure of gap-type battery modules is not compact enough when they are grouped together, and there is no interaction force between the individual cells. When subjected to external shocks, the cells in the battery module will collide with each other, and the This causes the cell to fail

Abstract

Embodiments of the present invention provide a side panel structure, a battery module casing, and a battery module. The side panel structure includes: a first side panel and a second side panel arranged at intervals, and a first side panel and a second side panel The side plate includes a plurality of limiting grooves distributed successively in the length direction of itself; the stop member is located between the first side plate and the second side plate, and is connected to the first side plate and the second side plate through opposite ends. The side plate and the stop member are movably arranged along a plurality of limiting grooves, and can be limited in each limiting groove. Therefore, the side plate structure in the embodiment of the present invention can not only provide expansion space for the single cells in the battery module, but also ensure that the single cells will not collide with each other due to vibration.

Description

technical field [0001] The invention relates to the technical field of battery equipment, in particular to a side plate structure, a battery module casing and a battery module. Background technique [0002] During the use of the hard-shell battery module, the battery cells will generate gas and expand, and a large expansion force will be generated between the battery cells, the battery cells and the shell of the battery module. The expansion force usually affects the service life of the battery cell and the battery module, and will cause the battery capacity of the electromagnetic module to decrease. [0003] In order to solve this problem, the current hard-shell battery modules usually reserve a certain gap between the cells to reserve expansion space for the cells, but the gap reserved between the cells can only be used in the initial stage of cell expansion. Function, when the cell continues to expand and two adjacent cells are in contact, it will not be able to continuo...
