Tesla has filed for a new patent on a design for a liquid-cooled charging connector, like the one used at its Supercharger stations.

With the advent of faster-charging electric vehicles, charging station manufacturers need to develop higher-powered DC fast charger and those machines generate more heat that needs to be dissipated.

When introducing its new V3 Supercharger, Tesla fixed this issue for the cable with a new “significantly lighter, more flexible, and more efficient” liquid-cooled cable than their previous air-cooled cable found on the V2 Superchargers.
