The trip was about 850 miles. We paid 95 dollars to charge, including 2 overnights where we paid full price for the RV spot. Typically you need their most expensive site to get the 50 amp breaker and its 60-80 feet long and you need less than a quarter of it. I think we used about 225 kWh of energy, worth about 25$. The parks made 70 dollars off of us, hopefully in the future they will give better rates, but I am happy for them to make money rather than it going where the money for gasoline goes. If we had been in a 30 mpg car, we would have used about 28 gallons of gas, and that would have cost 144 dollars at 4 dollars a gallon.
At the end of the trip I have learned a bunch of lessons.
Questions to ask of the RV park:
Do you have 50 amp service? Do all of your sites have 50 amp service? How long have you had 50 amp service? ( sneaky way to find out if the breakers are really old ) How much will you charge for a 2 or 3 or 4 hour charging stop?
If the breaker looks really old, stick around a few minutes and make sure it will be ok… go back and re-read EV Noob Lesson #1.
Is there a restaurant within walking distance? A hotel/motel within walking distance? If you ask if one is close by, they might assume you are an RV and are towing a vehicle and you want to drive to it.
Is there something you want to spend time at within walking distance?
I think that driving cross country in an EV is the civilized way to drive. Get up early and drive a couple of hours, then stop for a relaxing breakfast while you charge for 1-2 hours. Drive another 2-3 hours and then stop for lunch and an afternoon seeing something you want to see, while you charge for another 3-4 hours. Drive a couple more hours then stop for dinner and charge again. Then after dinner you drive a little more to a final stop for the day where you charge overnight.
If you start with a nearly full battery and your total driving time is about 6-8 hours, your time for charging stops will be about 6-8 hours. I did almost no research on what to do while at the charging stops. Unfortunately at 100 degrees plus outside, it wasn’t compelling to do much of anything outside. The next time I do a long trip like this, I plan to do it up the coast. Roads with lower speed limits that make you ( let you! ) cruise at 50 mph or a little less will actually improve your total mph when you include the charging stops.
We recorded data by taking pictures of the data screens in the car with a digital camera, we forgot a couple of key data points and an unfortunate number of the pictures were impossible to read because of glare. Yes I know I should have planned a better way to take data but I only took a minute to pack and did almost no trip planning…
