Tesla warns against wet towel trick to speed up Supercharging

Tesla says: > Placing a wet cloth on Supercharger cable handles does not increase charging rates

Earlier in the article: > Plugged in at 2% SoC - ramped up to 147kW as normal and thermal throttled at 34% down to 58kW. Slapped that room temperature soaking wet rag and it climbed back to 119kW where it hit the internal charge profile limit.

So it seems it _does_ increase charging speed.

Also nitpick: Article says: > Sending high-voltage current through small cables creates a lot of heat.

High voltage has absolutely nothing to do with how much heat is generated. Actually, the higher the voltage, the less heat is generated for the same power transfered. It depends on current, and higher voltage is used precisely to transfer high power with less current, thus less heating loss.

I find it funny that people writing stuff for web about electric cars have no idea about basics of electricity.

It's wild to think that people would use the same sort of trick you used to use to revive a dead Xbox to charge their car faster...
