Something rather interesting just occurred to me, of great interest to people like me in places without superchargers: A Model 3 should basically be able to "supercharge" on a CHAdeMO charger.
Tesla superchargers can deliver 120kW per vehicle (145kW shared), while CHAdeMO can only deliver 62.5kW. Tesla packs generally charge to 80% in 30 minutes, full in under 1 1/2 hours.
Versus a Model S, the Model 3 has a target drag coeff of 15% less, and a smaller frontal area. The drag is probably something like 70% as much. Rolling resistance-wise, despite having more steel, it's a smaller car, smaller packs, and even the tires look lower rolling resistance; I wouldn't be surprised if it's also 70%. In short, a Model 3 should use about 70% as much power per mile.
With an EPA highway range of "at least 215", lets look at 215 miles. Scaling Model S numbers, this would mean something like a 50kW pack. 80% is 40kW. Divided by 62.5kW, this is 38,4 minutes to reach 80% - only 28% slower than a supercharger. And after that, the CHAdeMO and Supercharger become roughly equal, as the supercharger would have to cut its charging rate for cell equalization.
In short, CHAdeMOs should be practically superchargers for Model 3s. This is a *very* interesting realization for me!
Concerning actual Tesla superchargers: Model S / X owners should rejoice - if you're sharing with a Model 3, the other vehicle won't need to be drawing as much power.
If the supercharger divides the charge times equally rather than dividing the current equally, the Model S should get 98 of the 145 shared kilowatts, meaning that you're still charging at 82% of the rate you would be if charging on your own. On the other hand, if they divide current equally rather than charge times, it's no loss to the Model S, but a big win to the Model 3 - the average charge rate over the first half hour would be 90% of the theoretical maximum if it was charging on its own.
Now, there's a couple things that could work against this. The Model 3 could be less efficient than it seems - although not tremendously so, or they wouldn't get significant range out of a small pack. The pack could be larger (and thus the range larger) - although not tremendously so, surely no more than 60kWh. There's some small losses I'm not accounting for, and the first thirty minutes isn't constant speed charging, there's still a bit of taper in that first 30 minutes. Nonetheless.... Model 3 should significantly improve the charging situation in areas with a shortage of high power chargers.
