From the Supercharger threads, I see Maumee is live! I think you should try doing this in one day and set the new Toronto-Chicago EV speed record.
As strategy, you'll want to use as little energy as possible until you get to Maumee to reduce the time spent charging. Once you're on the Superchargers you can open it up.
Do a 100% charge in Toronto and keep the battery warm by having the charge end just before you leave, and pre-heating the cabin. Keep Range mode off to fully heat the battery. Once you start driving turn Range mode back on. Keep the heat cool but comfortable.
Drive 100km/h and draft trucks or buses until you get to Maumee. On the first part of the trip you'll be limited by the charge time, not drive time, so driving faster will be counterproductive. You'd lose more time from charging than you'd gain from a higher speed.
Stop at Chatham Downtown mall, which at 240V 70A is the fastest station between Toronto and Maumee. Have a look at the W/km you used on the first leg, and add just enough charge to get to Maumee (plus whatever buffer you're comfortable with).
On the leg to Maumee keep an eye on W/km and remaining distance. Slow down and draft a truck if it doesn't look like you'll make it.
Once you're on the Superchargers you're home free. I bet you can do the trip in under 12 hours if everything goes right. And have a backup plan if it doesn't! :smile:
