Electrical Contacts for EV Battery Disconnect
and DC Switching Systems

  • High-Voltage DC Switching and Contact Performance

    EV electrical contacts must interrupt and carry current under high-voltage DC conditions, where arc suppression, thermal management, and contact resistance are critical. Unlike AC systems, DC switching demands materials that manage sustained arcs and ensure reliable cycling. Checon supports EV applications through vertically integrated capabilities spanning contact materials, discrete components, and integrated bus bar and power assembly systems.
