1Object-affected harmful factors
If a flame-retardant sheet with an inclined surface is attached to a battery module, then heat transfer between battery modules is reduced, but alignment accuracy is degraded
Solution Approach 1:
The pressurizing device is divided into two independent pressurizing units that can apply pressure in different directions (first direction along the inclined surface, second direction perpendicular to the first direction). This segmentation allows independent control of pressure application in each direction, enabling precise alignment while maintaining effective attachment to the inclined surface for heat transfer reduction.
Solution Approach 2:
The solution introduces a second pressurizing direction perpendicular to the first pressurizing direction. The first pressurizing unit applies pressure along the inclined surface in the first direction, while the second pressurizing unit applies pressure in the second direction (perpendicular to the first). This two-dimensional pressurizing approach enables precise alignment control on the inclined surface while maintaining effective attachment.
2Reliability
If a flame-retardant sheet is attached to prevent flame transfer, then safety is improved, but heat transfer between battery modules increases
Solution Approach 1:
The pressurizing device applies pressure locally at specific contact points on the inclined surface of the flame-retardant sheet. By concentrating pressure at optimized locations (through the two pressurizing units acting in perpendicular directions), the attachment achieves effective flame barrier functionality while minimizing thermal interference and heat transfer between battery modules.

AI summary
A flame-retardant sheet attaching device is disclosed. The flame-retardant sheet attaching device may include a first pressurizing device configured to move in a first direction and apply pressure to a flame-retardant sheet, and a second pressurizing device configured to move in the first direction, the second pressurizing device having at least a portion inserted into a groove of the flame-retardant sheet. The flame-retardant sheet may be configured to move, based on the movement of the second pressurizing device, in a second direction, perpendicular to the first direction. The first pressurizing device may be configured to restrict the movement of the flame-retardant sheet in the first direction, when the flame-retardant sheet moves in the second direction.
