If you're above about 50% SOC, the charging time is likely the same as a 50kW charger. Where additional charging time will be added is if the battery is closer to empty.
We drove up to Doheny State Beach today and stopped at EVoasis. We pulled in with 4 charge bars, 31/34 on the GOM, and 6 battery temp bars. The charger activated easily with my Chargepoint card and the Fuji connector was simple to attach and detach.
The charger said I started with 38% charge and I selected to charge to 85%, for which it estimated 59 minutes which is slower than I expected, but in fact we got sufficient charge in 25 minutes. They have a comfortable lobby with TV, free Wifi, and refreshments (photos to come in the EVoasis thread). But forget about walking to Costco for a shopping trip! I didn't even have time to finish my Pepsi before it was time to go.
I checked the Fuji display a few times:
38% start, 59 min remaining to 85%
43% 384V 59A 56 min remaining to 85%
71% 395V 50A 41 min remaining to 85%
78% 395V 41A 37 min remaining to 85%
I had enough charge and it was clearly ramping down the charge rate, so I stopped it there. Car showed 8 charge bars, still 6 battery temp bars, and 69 GOM. Chargepoint reported I had used 8.522 kWh in 24:54, which should have cost me $6.23. If I instead figure getting 40% charge of 21 kWh usable capacity that's 8.4 kWh. I don't know which is correct or if that's just the difference from charger inefficiency. Oddly both the Fuji unit and Chargepoint web show the cost as $0, so either EVoasis is celebrating the opening by giving free charging, or there was an error and I owe Angus.
Kudos to EVOasis for charging by the minute. Not only does this make it less expensive for (I think) typical usage, but given the CHAdeMO ramp down people will see the diminishing returns on their dollar and will not be so likely to hog the charger when they don't need it, as they would if there were a flat fee for charging.
As for cost, I averaged 4.6 mi/kWh for this trip. My overnight charging at home costs $0.095/kWh accounting for L2 charger inefficiency, so miles driven on home electricity cost 2.1 cents. If I had paid $6.23 for 8.4 kWh that's $0.74/kWh or 16.1 cents per mile, almost 8 times as expensive as home. But the total trip would have cost $7.81 whereas if we had Just-Driven-the-ICE it would have cost $15.27. Without EVOasis driving the ICE would have been our only reasonable alternative.
Oh, and that Pepsi I drank cost me $3 for 250ml, whereas at home it costs only $1.89 for 2000ml, over 12 times as expensive. Sure did taste good right then and right there though.
