I dont have any CHAdeMO stations near me (southeastern USA)... however the only thing stopping my chargers from running on it is the protocol and connector.
If you could tell the station to supply 340v DC at around 38amps, it would max out my 13kw charger.
If I am remembering correctly, part of the protocol is a quick 500v isolation test before starting, so I would add a little filtering for that, but I use 600v FETs.. so off the top of my head I cant think of a reason why it wouldnt work off DC. I may have to de-rate the bridge rectifiers some if theres a thermal issue, since DC would only use half the bridge, the heat might not spread out as fast... when you're pushing that much amperage through silicon, getting the heat out is always the limiting factor.
all that said, as long as you dont try to overdrive it too far, you should be able to run any SMPS type charger on CHAdeMO.
I wouldnt try "normal" CHAdeMO charging of directly into the battery.... only because zeros are 116v bikes, and most CHAdeMO stations will not dip that low, even though the spec says they should. Most are expecting cars in the 400v area, and wont dip low enough. That is the reason Zero dropped their CHAdeMO support in the first place.
