Chademo charges a Leaf (or similar class car) to 80% in around the same time as SuperCharger does for a Tesla Model S, doesn't it?

If you want 100 miles of range, sure.

I can tell you charging chademo on a Model S is much slower.

Of course, but Chademo isn't designed for a Model S, it's designed for more affordable cars with smaller capacity batteries. The market requirement for both a Leaf and Model S DC fast-charge is the same: charge to roughly 80% capacity in 30 minutes.

As I said elsewhere, the Chademo connector can support higher currents when there is a need. When there are Leafs (and Souls? I think think those are the only two in the US on Chademo) with 200mi range batteries, I'm sure we'll see the existing chargers upgraded to the higher current capability.

You sure about that? When the model s chademo adapter came out Teslas were breaking chademo stations left & right because they weren't engineered to handle 25min @ 45kw.

I'm not aware of and chademos above 60kw today while Tesla has a while infrastructure deployed right now.
