Module structural components—End plates + Insulation + Fastening (Source: Douyin): Standard practice: Aluminum alloy end plates (Source: Dagong); Core elements: Insulation sheets + foam (Source: Douyin); Note: Steel strap fastening (Source: Patsnap).
I.
End Plates
Aluminum alloy: Lightweight and high-strength (Source: Dagong); Thermal conductivity: Excellent heat conduction aids dissipation (Source: Douyin); Hollow design: Cut-out design reduces weight (Source: Dagong); Dimensions: 169×175×19.5mm (Source: Dagong); Composite: Composite end plates increase rigidity (Source: Patsnap)—End plates: Aluminum alloy + thermal conductivity + hollow design (three key features).
II.
Insulation Sheets
End plate: End plate insulation sheet (Source: Douyin); Side: Side insulation sheet (Source: Douyin); Epoxy: 0.5mm epoxy board (Source: Douyin); Positioning: Positioning insulation sheet (Source: Patsnap); Bottom: Bottom insulation plate (Source: Douyin)—Insulation: End plate + side + epoxy (three locations).
III. Foam
Between cells: Foam between cells (Source: Douyin); Top beam: Anti-impact foam for the top beam (Source: Douyin); Cushioning: Shock-absorbing cushion pads (Source: Patsnap); Thermal insulation: Thermal insulation pads (Source: Patsnap); Compensation: Expansion compensation (Source: Douyin)—Foam: Cushioning + Thermal Insulation + Compensation (Three functions).

VI.
Housing Components
Top cover: Module top cover (Source: Douyin); Base plate: Insulating base/protective plate (Source: Douyin); Explosion-proof: Explosion-proof valve with four screws (Source: Douyin); BMS mount: BMS mounting base (Source: Douyin); Service window: Maintenance access window (Source: Douyin)—Housing: Top cover + Explosion-proof valve + Service window (Three components).
7. Procurement Recommendations
First, select end plates (aluminum alloy); second, configure insulation (epoxy insulation sheets); third, add foam (for cushioning and thermal insulation); fourth, specify busbars (copper, aluminum, or CCS);
and fifth, verify fixation (steel straps or tie rods)—structural components: end plates + insulation + fixation (the three core elements).
