    I've understood that Tesla (and other EV producers) discourage the use of extention cords when charging. This must be a safety issue?*

    For example: if I charge from a 220V 16A outlet and I use a cord only rated for 10A it could get hot and start a fire. The way I've understood though is that the car (Tesla) will sense the increased resistance and lower the current flow? Or maybe stop charging all together?

    However, if I were to charge with a quality extention cord , with the proper dimensions and insulation, how would that be a problem? And would there be any way the car could "know" that there is an extention in use?

    1) stop charging and say "extension cord detected" for an error.

    2)The correct answer is: it won't know the difference.

    This topic has been discussed at large in other areas.
