Tesla engineer warns against using extension cords at Superchargers

[Zprime29]

I seem to recall reading A2Z responded to that post by the Tesla engineer and said A2Z will claim liability if their cable is shown to be the reason of failure. If the connectors are the same as our free adaptors as built by Tesla, the only concern then is the cable portion over heating. Easily solved with a temp sensor that stops the charge just like the 2 already in the current adaptors. I don't think I'll be buying one, but if gifted one (from A2Z) I would use it without fear.

Just received an email stating “DC | NACS Extension Cord | 6-9 FT (2-3 meters) is available now!”
However, the website still just says coming soon.

it's amazing how much time we devote to discussing 'extension cables', as, in reality, every cable is an extension cable - there is no 'direct run' to the power plant.

Yeah I got that e-mail as well. I have an NACS extension cord in my cart but thought I'd wait. The copy on the product page is still showing a variable length of 6' to 9'. I'd hope that I'd be able to back the truck into charging stalls with whatever cord length they have available.

I guess we are just wondering what type of extension cord beyond what Tesla provides could handle the high current required for ~150kW for an extended time.

True, but when the cable is carrying 100 times more power than a household extension cable, engineering and safety issues become a lot more significant. Probably need to pay attention to what the actual engineers are saying.

what I really mean is that some always cringe at the notion of using any 'extension' cable, just because, well, it's an 'extension' cable. The term does mean by default that it is 'less than' the other cables that already handle the power. My point is that ANY wire, by nature, is AN EXTENSION CABLE.
