You could do that trip with your eyes closed! Don’t even waste your time worrying about it. Here is what you need to do.
1- Create an account on the Electrify America app, add a credit card, and sign up for the $4 tier account. You will save more than $500 on this trip alone. After the trip, you can cancel the membership and fall back to a regular account, but trust me, you’ll see more than $4 benefit.
2- Use PlugShare to pull up all of the EA chargers along the route you’ll take. I’ll reply again in a second showing you that map, but you can actually skip about half the chargers b/c there are so many along your route.
3- Start off with 90-100% SOC as you leave your house. Go to the furthest charger that you can (your car will want you to arrive with 15% SOC at each destination, so follow those rules gives you buffer for cold weather, head winds, etc) (if this trip is during colder months this is also safer so even if you use 5-10% more you’re ok). You’ll then want to charge however long you need to get to each next charger.
4- While at a charger, plug in first so you can get that stated (anticipate 20-25min stops each). Plug in the NEXT charger you want to hit. Ideally you’ll charge from the ~15% you arrived to no more than 80%. So that means you are only actually using 65% or going about 130 miles. So the next charger you find should be no more than 130 miles away. Plug in that charger, and start the nav. And then it shows you arriving with 0% — just wait until that says you’ll arrive with 15% and then set off. Easy…..
Hope this helps but i may have left out details you Want. We did Cleveland, Ohio to the Tennessee Smokey Mountains, a similar distance as yours. It was 500+ miles each way. Do keep in mind that 9-10 hours of driving will carry around 2 hours of charging (4 stops at 25min plus some wiggle room = 2 hours) — cheers and safe travels!
