Battery Pack Side Plate Structure for Module Swelling Control

The patent employs a flexible pouch structure for battery cells that can accommodate volume changes during charge/discharge cycles. The pouch type battery uses flexible packaging materials that allow controlled expansion and contraction, preventing rigid structural failure while maintaining lightweight characteristics. This resolves the contradiction by enabling the flexible shell to handle the swelling issue while preserving the weight advantage of pouch-type batteries.

The patent divides the battery system into modular units with optimized spacing and arrangement. By segmenting the battery module into smaller, strategically positioned cells with adequate thermal management channels between them, the design achieves high space utilization while maintaining effective heat dissipation pathways. This segmentation allows compact configuration without compromising thermal performance.

The patent converts the harmful heat generated during charge/discharge into a manageable parameter through optimized cell design and arrangement. By strategically designing the pouch structure, electrode configuration, and thermal management system, the heat that would otherwise cause electrolyte vaporization and side reactions is channeled through controlled pathways. This transforms the harmful thermal effect into a controlled parameter that enhances durability while maintaining operational efficiency.
