Five Critical Material Applications in EV Chargers
From high-power converter assemblies to the charging connector, OPUTE materials support thermal control, insulation, environmental protection and reliable assembly.
Power Module Thermal Interface
A single correctly sized silicone thermal pad can fill the interface between an IGBT, SiC or power-conversion module and its heatsink or cold plate. Dispensable thermal gel is an alternative for suitable assembly designs.
Magnetic Components Potting
Silicone potting protects inductors, transformers and related magnetic assemblies while supporting thermal management, electrical insulation and vibration resistance.
PCB Protection & Component Fixing
Conformal coating provides a protective film for exposed circuit boards. RTV silicone adhesives can be used locally to secure components and solder-joint areas where appropriate.
Charging Gun Potting & Sealing
Selected insulating silicone compounds can protect internal cable terminations and connector cavities, while RTV sealants support enclosure and cable-entry sealing.
Enclosure Bonding & Sealing
Neutral-cure silicone sealants help bond and seal selected charger housings, seams and interfaces where moisture and environmental resistance are required.
Materials Applied Where Protection Is Needed
Thermal interface materials are placed between power-device surfaces and a compatible heat sink or cold plate, while silicone potting and coating materials are selected for specific electronic assemblies.
Charging connectors and enclosures require careful evaluation of insulation, mechanical strength, adhesion, cure chemistry and environmental exposure.
