Wow, I did a bit of research and some basic math and found out that the 50 AMP charger for a Tesla draws 40 amps at 240 volts (10 kw). Or to put it another way, 80 percent of the maximum available power at a 50 amp pedestal. Furthermore, a complete charge at that rate would take up to 7 hours. NEC allows 7 50 Amp pedestals per 200 amp service loop. 5 Teslas charging on that loop would take 100 percent of the available power for that entire loop, leaving the 7 RVs completely without power.
A complete charge for a Tesla would cost us around $7.00 (10 cents per kwh). It is our experience that a fully electric coach costs us around $5.00 per day in electrical costs, so the Tesla is nearly a 50 percent greater energy hog than a 45 foot Prevost (provided the Tesla only needed one charge that day. It is entirely possible that with it's 250 mile range a person could run it dry in the morning after charging all night and need another full recharge that same day). No way electric cars can share the current electrical grids in RV parks.
I'm really glad you are doing the research but your numbers make no sense at all. If you have 7 50 Amp pedestals and 5 of them have a Tesla charging on them, that leaves you only 2 spots left.
Where would you even plug in the 7 RVs if the pedestals are already taken? What is the likelyhood of you having 5 Teslas charging at maximum draw at the same time? This makes no sense. So the Tesla uses an extra $2.00 in electricity. How much do you charge for one of your sites? How much water does the Tesla use (probably close to zero). How much sewage does it produce (again, close to zero)? If you are completely honest with yourself, you'll see that a Tesla renting one individual spot and taking one outlet only is good business for you and for the environment and for your customers.
Note, I'm not suggesting the Tesla share a spot with the camper. I'm suggesting you rent out the Tesla spot and camper spot separately.
Those Teslas will draw maximum power for 7 to 8 hours, and since most everyone would be charging them overnight, they would be drawing that power at the same time. People with electric cars aren't going to pay for two sites, one for their RV and one for their car, they are going to want to charge their cars at their sites and it is not feasible in parks that have constructed their electrical grids to current NEC specs.
Now if someone wants to rent a site for their electric car and then rent an RV site for their RV, fine. But I would peg the number of electric car owners that are going to pay well over $100.00 a night for two RV sites at just about Zero.
I get where you are coming from but the pendulum doesn't have to swing to such extremes. For most EV drivers the ability to plug into a 120 plug on the site pulling 12 amps would suffice. EV drivers think differently then gas drivers. We rarely run the "tank" to empty. An overnight charge at low current (12 amps) would many times more than suffice to top things up. For situations like this the campground could simply stipulate what plugs can be utilized by the EV drivers and how much extra they would be charged. They do this with dog right now. Eg 3 bucks a day. EV drivers are not villains. We are not looking for free energy. We are not necessarily "greenies" as one poster implies. We simply enjoy hi performance technically advanced cars that have a refined ride. Why would any business try to avoid that kind of clientele. The hostility towards EV's by some surprises me. Kinda weird. Lots of silliness out there, or maybe just ignorance. Just sayin.
If you don't like the concept of EV's don't EVER drive one. You will be ruined for driving any car with a tail pipe afterwards. If you are the type that drives 400 miles at a shot with no breaks then an EV is not for you. However if you stop for a break every two or three hours then they might work for you. You will change how you do some things but change is not necessarily bad.
Just came back from supper. Car is now in the garage charging. We always charge on saturdays so we can go for a sunday drive. We charge sunday night after the drive and then not usually again till mid week. For our rhythm of life that works. We seem to go between 3 to 4 dollars of power per week. meh.... We have a little diesel car too. It doesn't get a lot of miles anymore as the go to car is the electric. Just a way fun car to drive.
Worth taking one out for a test drive although the choice of electric vehicles is going to explode in the next 2 years.
Enjoy
