2.2 Cell Retention & Mechanical Support

Designing effective cell retention and mechanical support is crucial for ensuring the safety and longevity of the battery module. Engineers must create mechanisms that securely hold individual cells in place, preventing any movement or damage resulting from vibration, shock, or natural cell expansion and contraction during cycling. For pouch and prismatic cells, managing and maintaining compressive forces is a key consideration. The design must also ensure adequate spacing between cells for electrical insulation and to accommodate thermal expansion. Throughout this process, Design for Manufacturability (DfM) and Design for Assembly (DfA) principles are applied to ensure the retention system can be efficiently and reliably produced and assembled.
