Charging Guns
How can we help build a world in which passengers have access to Level III DC (Direct Current) fast-charging infrastructure? A key piece of that puzzle is the reliability of charging guns (connectors).
Incorporating our thermally conductive, silicone protection and assembly materials into charging gun designs can bring a more reliable driving experience to consumers and significantly enhance the EV charging process – improving reliability, safety, functionality, and efficiency.
Charging gun application areas
Thermal Management
We have a wide range of high-performance silicone materials designed to support the transfer and release of heat generated from high-current charging gun cables, including:
- Silicone heat transfer fluid
- High-consistency silicone rubbers (HCR)
- Liquid silicone rubbers (LSR)
- Sealants and adhesives
- Encapsulants and pottants
- Gap fillers
Protection and Assembly
Interiors of printed circuit board (PCB) modules, charging gun connectors and charging housing cabinets contain sensitive components, such as capacitors, semiconductors and magnetic devices, and power devices with high heat output.
DOWSIL™ silicone conformal coatings, pottants and encapsulants can be used in rigid and flexible circuit boards, connector pin sealing, sensitive components, and other fine-pitched designs to protect against environmental contaminants and heat while meeting varied reliability standards.
Engineering Resins
Public charging guns can face harsh weather conditions ad heavy use. To endure these challenges an extend lifespan, the thermoplastics in charging gun housing and handles need to be modified with additives.
PARALOID™️ Impact Modifiers enhance toughness and impact resistance, even at low temperatures, in various engineering resins for EV charging guns. Our modifiers also support processability and mechanical recyclability for reuse in other demanding applications.
Exceptional Performance
VORANOL™ polyols and ISONATE™ isocyanates provide unique, cost-effective formulation strategies for thermoplastic polyurethanes (TPUs) for charging guns and electrical cables.
Longevity
Invest in quality fluids to ensure freeze protection and longevity for EV charging infrastructure.
DOWFROST™ and DOWTHERM™ Heat Transfer Fluids can aid in keeping charging station components cool through effective heat transfer, while helping to extend the life of the system.
Charging Cables & Busbars
Smarter, more intuitive, and more electric vehicles mean more complicated internal components. Electrical cables and wire connectors play an important role in vehicle design, whether it’s for converting voltage, streamlining communication, or enabling faster charging. With silicones, smaller more complex designs can be achieved.
Thermal Management
DOWSIL™ silicone cooling fluid provides high thermal stability and excellent electrical insulation in a wide temperature range – making it suitable for charging guns and other electrical equipment that operate at high or extremely low temperatures.
SILASTIC™ high-consistency silicone rubbers (HCR) and ceramifying HCR are also reliable materials for coolant tubes, charging cable insulation and busbars. They offer high thermal conductivity that supports transfer and release of heat generated from high-current charging gun cables or for high-voltage cable insulation with excellent thermal resistance, mechanical properties and high flexibility.
Charing Station Housings
MobilityScience™ offers a wide range of thermal management and protection technologies that can help address your specific challenges in EV charging station housings – helping unlock reliability, charging speed, safety, compatibility and efficiency.
Charging station housings application areas
Thermal Management
Dow’s high performance silicone thermal management materials, including sealants and adhesives for shell and door applications, are designed to address varying requirements for adhesion, component staking, vibration damping, and compression.
VORATRON™ Polyurethane Systems allow the development of thermally conductive adhesives, gap fillers and pottants, that help enhance safety and fire protection.
Protection and Assembly
DOWSIL™ silicone adhesives offer durable bonding, sealing and gaskets for charging pile cabinet doors, helping improve safety and performance. DOWSIL™ silicone foam offers rapid room-temperature curing, crevice-filling, vibration-buffering, and excellent heat and flame protection.
We also engineer VORAFORCE™ composite solutions, which offer significant load bearing strength, corrosion and UV resistance, and improved flame retardancy properties, for cable management applications such as cable trays.
Toughness and Resiliency
Charging station housings must be resilient to tough weather conditions and public use. Contributing to extended lifespan and mechanical recyclability, PARALOID™ Impact Modifiers facilitate improved durability, toughness, impact resistance and processability in the full range of engineering resins for EV charging housings.
Power Electronics
This new era of e-mobility demands safer, more durable vehicle electronics that are sensitive to environmental contamination and heat. From PCB modules to charging stations, MobilityScience™ has innovative materials that can not only protect power electronics and devices from harmful contamination, but also support high-power fast charging.
Informed by decades of experience in protectives for electronic control units (ECUs) and power electronics, our broad range of DOWSIL™ and SILASTIC™ technologies can be tailored to meet desired performance targets, including:
- Thermal conductivity
- Easier processing
- Next-level durability
- Corrosion-resistance
- Proper insulation for high-voltage systems
Thermal Management for IGBT / Inverters
Dow offers different types of high-performance thermal management materials for IGBT and inverter applications, including:
- Compounds
- Gap fillers
- High-temperature gels
- Pottants
- Encapsulant
Thermal management and protection for control units
DOWSIL™ electromagnetic conductive adhesives and conformal coatings can be used in the control box and PCB of X-DC power electronics control units.
Structural Security
VORATRON™ polyurethane systems help ensure strong bonding and enhanced performance, even under extremely demanding conditions.
These high-strength adhesives and sealants are versatile, providing adhesion across a wide range of substrates such as plastics, metals, cement, wood and ceramic. They offer easy handling with long pot life with fast cure times and excellent fatigue resistance.
