Reply #3: They pretty-much do for Level 1 (120 VAC) and Level 2 (240 VAC). [View All]

But Level 3 charging is technically complex and
acceptable standards haven't been worked-out yet.
The connectors must carry very high power levels
while still being easy to mate/demate (so light
in weight!) and must survive many mate/demate
cycles without loss of performance or even
outright damage.
