Insulation sheet for EV battery
ODM
Based on the drawings provided by the customer, we evaluate and propose manufacturing methods and equipment to finalize specifications, thereby delivering cost-effective solutions.
Feasibility study on realizing customer drawing specifications
Proposal for applying insulation sheets to EV battery cases
| Specification meetings regarding drawings to be submitted to the client |
|---|
 |
| Evaluation of construction methods and structures meeting specifications |
|
| Specification evaluation using existing and prototype dies (adhesion strength, insulation properties, and sheet defects such as air bubbles, cracks, and wrinkles) |
|
| Evaluation of mass-production feasibility (e.g., assessment of automated machinery) |
Verification of insulating sheet lamination via room-temperature and high-temperature pressing
An evaluation of whether heating the insulating sheet improves its conformability to the aluminum during the press-bending of an aluminum sheet laminated with said insulating sheet.
Dielectric strength test of an insulating sheet laminated to an aluminum plate
A test to check for pinholes or cracks in an insulating sheet by performing a withstand voltage test.
