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.
In 1977 I was asked to invest in this new upstart company by one of it's founders (who shall remain nameless here). I just could not see for the life of me what this company was going to accomplish or how its product would ever be used...
They wanted $1000 dollars from me. I said "I am sorry I just cant see it"
That company was Microsoft and had I invested the $1000 I would be worth about 60 to 100 million today if I continued to hold the stock and reinvest.
The same thing happened to me when I heard about a new company/idea called Fed Ex...I thought who the hell needs anything overnight?
I learned my lesson after that.
Well needless to say sometimes our shortsightedness is our worst enemy.
And if you can plug in your Tesla ( a great car by the way) at your house overnight why not at the RV Park?
Who says it has to be a 3 hour recharge?
