No, not I. Although our Tesla did go on an adventure involving a 100 mile detour earlier this week, I'll recount that later.
A friend of mine is driving from CA to NY to visit family. He's going out to do some work on his parents house and stay for a month or so. He's bringing his wife and the cat, stuff to work from NY (monitor, standing desk) and art supplies. It's a full-on American Road Trip. The goal is not to explore the US but to banzai it. They are doing the longest days they can stand and pounding down the interstates. The longest day is 870 miles.
The plan is for 3.5 days. They're driving a Tesla Model Y which has the advantage of being (I think) the fastest charging EV that can use the largest fast charging network available. It's a Dual Motor Long Range with a rated range of 316 miles. So it's a best case scenario for the trip from that viewpoint - but that's okay. We're not dealing with a megadollar Porsche that comes with a tech team at every stop to make sure the charging station is working, this is 100% consumer grade stuff that's available to everyone.
They are taking advantage of destination chargers, so in theory every day starts with a full battery. I say in theory because...well, keep reading.
Here are a few highlights of what they've come across:
- they ran into a few situations where they couldn't get full charging rate because they were having to share chargers with other cars. Basically, there's only so much power available. This stretched out the charging times a little longer than expected. Then they hit traffic in SLC because that's what happens there and because the Superchargers there are at an old-school style dealership in the middle of town. Day 2 was scheduled to have just under 2 hours of charge time, they estimate it was actually 2.5. The lesson learned there was to charge as much as possible at Superchargers in remote areas instead of busier areas. They never had to wait for a charger, just had a few that were a bit slower.
- at the hotel after day 2, their destination charger was blocked by a guy with a gasoline car. He didn't want to move because he had "valuable things" in his car. So they started day 3 with only about a half charge after having to deal with that. This slowed down day 3 slightly because their first Supercharger stop had to be earlier. This cost them 20-30 minutes.
- the limiting factor at stops has not been charge time, but the human factor. The people have to stop to pee more than the car has to stop to charge, and charging stops need to be planned in advance so you don't end up spending more time dinking around than the car needs. It took most of day 2 to figure this out. They're eating in the car (eww) to limit stopping time. They report that one of their stops was about 10 minutes longer than was required by humans.
- the Tesla display has a "glide path" that shows projected energy use over the course of a trip along with your current trajectory. He used that to dial in cruising speed to make sure there were no unanticipated stops due to high energy use. Using the glide path and planning charging stop tasks meant that on day 3, they were 8 minutes early on their projected ETA. 8 minutes over an 870 mile distance. They basically executed the plan the computer put together for them.
- today's trip is 720 miles and will have less than 90 minutes of charge time. Of course, they'll have to charge overnight the night before and the night after, but that happens while you sleep. Day 2 was 831 miles with 110 minutes of planned charge time.
- when they get where they're going, they'll plug in a mobile charger they brought with them and the car will live off that until they Cannonball back to California.
So, it is possible to do a banzai cross country road trip in an EV today. You can figure this out in theory but these two are actually doing it. Better them than I.
