Don't see where in that link the extension cord issue is mentioned.
I don't think anyone can fault a car manufacturer for this issue. Long extension cord with too small gauge wire will cause voltage drop. It's the same for any electrical load.
Actually now that I think about it, I guess they could include dynamic power factor correction in their charging hardware and software. But it seems like a silly extra expense just to correct for someone buying a cheap extension cord. I think my 100 foot 10awg cord that I used to power the neighbor's stuff after Hurricane Sandy was under $100.
"Complete discharge can happen even when the car is plugged in if it isn’t receiving sufficient current to charge, which can be caused by something as simple as using an extension cord. "
Yep, using the same care in choosing an extension cord as you would for work equipment and space heaters would be advisable with electric cars. Do not buy the cheapy cord.
