Ehhh - the *internal* wiring of an EVSE, how can that be a standards thing? Who cares if the charging cable has copper, steel or aluminum wiring, as long as it meets the current spec (and possibly the max resistance if that is important (voltage drop)?

This is steel wire with a copper plating. If you have enough cross sectional area, you can still have a low enough resistance. It's far stronger and cheaper than copper. And much harder to cut, and next to worthless on the scrap market. > Excellent idea - only problem is that the standards for the supply device has been set on copper for a few years now. :( I'll ask some of the guys next week about this problem (standards meeting in Berlin for wireless charging).
