Module structure and optimization descriptions The module structure surrounding battery cells should be optimized to maximize cell volume or weight while satisfying mechanical and thermal safety constraints. This section presents the basic module structure used in this study and summarizes the optimization process.
Conclusions This study proposes an optimization framework for a battery module structure that maximizes the energy density while satisfying both the mechanical and thermal constraints of pouch cell LIBs. To this end, mechanical and thermal models of module structures have been developed.
A battery module is a complex assembly of individual battery cells, housing, thermal management systems, and safety mechanisms. Selecting the type of cells to be used in an EV battery module is a crucial decision that impacts the vehicle’s performance, range, safety, and cost.
Selecting the type of cells to be used in an EV battery module is a crucial decision that impacts the vehicle’s performance, range, safety, and cost. The choice between cylindrical cells, prismatic cells, and pouch cells depends on a range of factors, including design, packaging, and performance considerations.
A thermal module-level model was used to optimize the battery module structure while satisfying the safety constraints, including the maximum temperature and temperature deviations. Chen et al. proposed a double-directional liquid heating system in a battery module.
From the contours, we can observe that the battery module with cylindrical cells and curvilinear cooling lines has lower displacement but experiences a slightly higher stress than the battery module with prismatic cells and C-shaped cooling lines.
