Daoke Dao Laser Welding for Automotive Battery Sensor Plastic Housings (EV): Insulating & Leak-Proof
Date:2026-02-25 14:57     Source:daokedao     Browse:5
Automotive EV battery sensors use plastic housings, which require insulating and leak-proof welding to ensure accurate battery parameter measurement and avoid electrolyte leakage. Traditional welding has poor insulation and sealing, leading to short circuits and electrolyte leakage, endangering battery safety. Daoke Dao plastic laser welding equipment provides reliable solutions. Suitable for insulating plastic materials such as PC and PP, the welds have excellent electrical insulation performance (breakdown voltage ≥2kV), preventing short circuits. The hermetic weld seam achieves a helium leak rate ≤1×10⁻⁹ mbar·L/s, effectively preventing electrolyte leakage. The low-heat process avoids plastic deformation, ensuring measurement accuracy. Compliant with IEC 62133 and IATF 16949 standards, it integrates into automated EV battery assembly lines with a welding speed of 2 sensors per second. The equipment supports small-size plastic housing welding with high precision. Daoke Dao supports new energy vehicle manufacturers to improve battery safety. Contact us for insulation test reports.
