Swiss Turned EV Charging Pins for Next-Generation Charging Systems
Direct answer: Swiss turned EV charging pins for next-generation 800V to 1000V charging systems require C18150 chromium-zirconium copper for thermal stability at 350 kW+ continuous current, 5-8 micrometers silver plating per ASTM B700 over nickel strike, and tight plus or minus 0.01 mm tolerances per IEC 62196-3, SAE J3400, and UL 2251 specifications. VOLCRIX has machined EV charging pins for next-generation high-power charging systems since 1991.

FAQ
What is the next-generation EV charging system voltage?
Next-generation EV charging systems operate at 800V to 1000V DC compared to legacy 400V systems. 800V is the current mainstream for high-end EVs launched from 2019 onwards, supporting 350 kW DC fast charging. 1000V is the emerging standard for ultra-fast charging stations. Benefits: reduced current for same power 350 kW at 800V requires 437A vs 875A at 400V, reducing cable size and thermal load. Higher voltage requires C18150 Cr-Zr copper for thermal stability, upgraded insulation, and reinforced safety standards.
Why is C18150 chromium-zirconium copper preferred for 800V charging pins?
C18150 Cr-Zr copper is preferred for 800V+ charging pins due to its superior thermal stability at elevated temperatures. Standard C11000 ETP copper softens significantly above 200 degrees C, losing mechanical strength and contact force. C18150 maintains its strength up to 425 degrees C due to chromium and zirconium precipitates that pin dislocations.
What is liquid-cooled charging and why is it needed?
Liquid-cooled charging uses dielectric coolant circulation through the charging cable and connector to remove heat from high-current charging pins. Liquid cooling enables 350-500A continuous current in compact cable designs that would otherwise require much larger cable diameters for passive cooling. Benefits: lighter cables 50-60 percent weight reduction, smaller charging guns, longer cable life, higher continuous current capability 500A vs 200A for air-cooled.
What is V2G vehicle-to-grid charging?
V2G vehicle-to-grid charging is bidirectional charging that allows EVs to discharge power back to the electrical grid during peak demand and charge during off-peak hours. V2G applications include: peak shaving for commercial buildings, frequency regulation for grid operators, backup power for homes, and renewable energy storage.
