摘　　要：软包锂电池模组中的压板设计对于模组整体至关重要。为了实现压板的轻量化设计,减小软包锂电池模组的质量,进一步提高软包锂电池模组的比能量,本文基于碳纤维复合材料设计了一种新型压板模型。研究了多种不同的压板模型,采用不同的金属材料和碳纤维复合材料,在极限压力下对每种压板模型的形变进行有限元仿真计算。比较仿真结果,选择最优方案,并通过实验进行验证。结果表明,本文提出的压板模型在极限压力下形变程度较小,整体结构没有损伤,同时具有极小的质量,符合软包锂电池模组的轻量化设计需求。The design of the pressure plate in thelithium pouch cell module is crucial for the overall module.In order to achieve lightweight design of the pressure plate,reduce the mass of the lithium pouch cell module,and further improve the specific energy of the lithium pouch cell module,this paper designs a new pressure plate model based on carbon fiber composite materials.Multiple different pressure plate models are studied,and finite element simulation calculations are performed on the deformation of each pressure plate model under ultimate pressure by using different metal materials and carbon fiber composite materials.By comparingthe simulation results,the optimal solution is selected and verified through experiments.The results show that the pressure plate model proposed in this paper has a small degree of deformation under ultimate pressure,no damage to the overall structure and has extremely low mass,which meets the lightweight design requirements of lithium pouch cell module.
