This study first compared the material properties and costs to determine the use of 45% by mass glass fiber (GF) reinforced nylon (PA). Based on the envelope, electrical performance, and insulation requirements given by the battery system,the structural design scheme of the integrated insulation structure battery housing has been determined. CAE analysis was conducted on this housing with integrated insulation structure. Equal proportion samples of the composite housing were manufactured using LFT-D technology and the insulation structure was integrated. Corresponding CFD analysis and insulation performance testing were carried out; Simulation analysis and sample testing have proven that the mechanical and insulation properties of this housing meet the design specifications, and compared to aluminum alloy housing, the housing also has the advantages of lightweight and low cost.
