NEMA 14-50 Question

Dangerous thinking by SilverString. Please do not use use extensions cords for charging, especially ones that are undersized and can burn your house down.

The car will sense a voltage drop when using an extension cord (probably if using incorrectly-sized wiring as well) and will drop the charging amps accordingly. This is a safeguard against burning your house down. I'm not sure if all EVs do this, but I know Tesla does.

This doesn't mean you should be reckless, but it's nice knowing that the car is smart enough to mitigate unscrupulous users.

Except that it is not reckless and charges at a steady 240/32A from 10 to 90% with zero heat at any point, anywhere. But never mind the facts, this has become a fear mongering thread. No need to continue.

I have run this extension cord long-term with ZERO issues:

No heat, no problems, charging everyday. Especially ia a hot south Florida garage.

I have a 15ft version of the same cable for when I'm too lazy to back into my garage.

Yup, keep doing what you're doing and things will probably be OK. Good luck.
