Laser Welding for Automotive EV Battery Pack Baffle Plates

Date：2026-04-15 09:24 Source：daokedao Browse：3

Battery pack baffle plates separate battery modules, preventing thermal runaway and ensuring uniform heat dissipation, requiring high flame retardancy, insulation, and structural strength. Traditional mechanical fastening has gaps, leading to uneven heat distribution, while adhesive bonding degrades under high temperatures. DaokeDao plastic laser welding provides a reliable joining solution for flame-retardant PP and PA66-GF baffle plates, complying with UL94 V-0 flame retardant standards and EV battery safety regulations. The laser forms a dense, continuous weld with tensile strength ≥24MPa, ensuring no deformation under battery expansion pressure. The non-contact process avoids damage to battery modules, with a heat-affected zone ≤0.25mm, maintaining insulation performance (insulation resistance ≥10¹²Ω). The equipment supports automated multi-point welding, with a production capacity of 85 pieces per hour, full parameter traceability, and online quality detection, helping battery manufacturers improve battery pack safety and thermal management efficiency.
