Abstract

The embodiment of the invention discloses a CTP battery pack structure simulation method. The method comprises the steps of obtaining a three-dimensional model and a corresponding bill of materials of a CTP battery pack; building a finite element model of the CTP battery pack according to the three-dimensional model, and building a finite element mesh model by taking a single battery cell in the CTP battery pack as a part; according to the bill of materials and the actual situation of the CTP battery pack, establishing the relation between the parts in the finite element model, adding the material attributes of the parts and loading boundary constraint conditions; the material attribute is the inherent attribute of the material; solving and analyzing the finite element model to obtain a simulation result of the CTP battery pack mode; according to the difference between the simulation result and the corresponding preset target value, the finite element model is solved and analyzed again after the part is optimized till the simulation result is higher than the preset target value. According to the embodiment of the invention, the technical problem of how to improve the structural simulation precision of the CTP battery pack is solved.
