The Tesla supercharging cables are pretty short, so they can also tolerate the higher losses associated with a thinner cable. They were even experimenting with a liquid cooled cable at one point in order to get thinner conductors and a more flexible cable by allowing to to be less efficient.

The experiment must have been a success, because the v3 supercharger uses liquid-cooled cables.

In fact, it is becoming standard in high-power chargers, with the new 175-350kW CCS units also using liquid cooling.
