check out this big one from clippercreek
https://store.clippercreek.com/level2/level2-40-to-80/cs-100-70-amp-80-amp-ev-charging-station

I think those are the ones suncountryhighway runs on their high-amp J1772 stations.  I've got some of them marked in the appropriate layer of the e-moto touring meta-map in google mymaps https://www.google.com/maps/d/embed?mid=1XlgoFYOj6345oZotVQ7KOuC_dBM&ll=38%2C-113&z=6

(BTW I could use help populating this map in other areas.  If Zero really does offer a configuration of 12kw with a single j-plug, these stations will be in high demand.)

Are you certain of this? I cannot find any information supporting it..
I tried looking at this picture to get details, but it's too grainy..

Yes, they've shown pictures of it and it's been discussed by Zero employees multiple times.

The new SR/F offers a Mennekes Type 2 inlet for the EU version of the bike. The J1772 is generally for North America.

Here You go, a picture of the mennekes type 2 inlet on the SR/F

https://blogautomobile.fr/zero-sr-f-quand-lelectrique-passe-la-seconde-326754#jp-carousel-326764

interestingly all 3 phases have a pin connected to it which give 2 possibilities :
* it's either a 3 kW or 6kW version on 1 or 2 phases and the other pins are just unconnected OR
* they are 3 phase chargers  !

Off topic but when I look at the charge port I see a bowl full of water in the rain when charging, maybe I'm missing a drain hole

There have been multiple reports of a drain hole, so not to worry.

I do as well, but onsite reports have mentioned drainage.

A drain hole can still get clogged with debris though.

I’ll just mention some hazards I’ve encountered and had to clean off my plastics while my bike is parked: leaves, bark bits, tree sap, and bird waste.

Since the spanish video
http://electricmotorcycleforum.com/boards/index.php?topic=8792.0
shows a standard 3kw version with only L1 + N pins (+ safety ground and control pins), this indicates that each charger is connected to a new phase. As long as each charger can provide the required voltage (which is the only sensible way to do it when designing from scratch), I think we can safely assume that each charger is connected to a separate phase. Thus the premium version will likely use two phases on a mennekes plug, for a maximum of 16A per phase, and 12 kw version will draw 32A on L3-N and 16A on L2-N and L1-N.  :)

This is what we try to explain to our customers, yet many of them insist on the 6.6kW unit instead of the 9.9.

I think I'd opt for the 10kw option, although I probably would not use peak power that much (to take it easy on the battery, although Zero finds 12kw / 0.8C acceptable judging by the SRF). It's just handy to have 10kw when it's necessary and you're in a hurry. The step from 1.2 to 3.3 or 6.6kw charging is really enormous, but from 6.6 to 10 is not that much of a difference. For a 80% charge you go from 8h (standard) to 2h12m (3.3kw) to 1h6m (6.6kw) to 44m at 10kw. Those last 20 minutes cost 800-ish euro while the use cases where those 20m really count are quite narrow.

Law of diminishing returns I guess.

Price is no object to a junkie

And yes I mean that as a joke. Mostly. Now if you'll excuse me I need to go figure out where I want to put a 4th charger on my SR.

made a screenshot of it. It appears indeed that each 3kW charger is connected to a single phase (which makes sense)

I personally know of 2 j1772 plugs that can do over 12kw.

The Delware House Travel Plaza on I-95 has 2 18kw j plugs and my sisters house in Florida where she recently installed a 40amp charger.

Uh, what voltage is her 40 amp charger running at? Because it would have to be... 450 volts to make 18kW
