220 Extension Cord

[TEG]

What does that EVES do? It looks like it gets mounted to your wall and hard wired into your home's electricity? And what is necessary to hook up to 110? Can I run an extension cord from any 110 outlet anywhere, say at a friends house if I'm away from home?

Yes, those big EVSEs hard wire to the house. As was said, it provides safety (to only power up the connector when a car is detected as plugged in) and tells the car how much power is available.

For 120V portable, say at a friends house, you use one of these:

And yet another adapter cable if using public J1772 charging (like what the LEAF & Volt use) that are starting to show up various places:

Some people end up with a lot of adapters and cables in their trunk if they are going on a long road trip and need to be ready for any type of plug they find.

I had 150' of extension made for me by a specialist. It's in 50' segments. I use it when I'm road-tripping, to charge at campsites or using a set of breakers I have that can go into most panels. I have some other scary specialty gear that lets me charge at 70A on the road as well. It is expensive and heavy... if I load it all into the trunk, there's absolutely no room left and it's at the 110 lb weight limit. But it's fun. If you decide to go the extension route, I can put you in touch with my guy.

I found that if you make the extension cord from the same guage wire you have in the wall and you use a high quality plug then you have virtually no drop in current due to the extension cord and the system does not heat up more than it would without one. this way you can have quite a long extension. I am running a 30m cord and have never had a problem, neither with stopped charges or heating of the wires.

About 20 years ago in a prosperous farming area of Japan, I saw an extension cord that must have been half a mile long running along a road from one farm building to another. The best I can remember, it was approximately 1.5 inches diameter. I did not investigate the voltage.
