Tesla patent application discloses new liquid-cooled charging connector

November 18, 2019

--

In a recent patent filing, Tesla Inc. (“Tesla”) disclosed new designs for a liquid-cooled charging connector, similar to the one used at its Supercharger stations.

On September 26, 2019, the U.S. Patent & Trademark Office published Tesla’s application for a new charging connector that is claimed to be more efficient than previous models. Using a “significantly lighter, more flexible and more efficient” liquid-cooled cable than its previous air-cooled cable, Tesla’s charger may aid in developments to dissipate heat generated by the higher-power DC fast charger stations required by more technologically advanced, fast-charging vehicles.

It is unclear if this technology is currently used in Tesla’s V3 Superchargers, or if this technology will be introduced in future Tesla charging stations.
