Where are you going to get ALL the electric for 300,000 electric vehicles? That's a lot of Amp Hours. KEN

It takes 27 kwh to go 100 miles in a Bev. On a 30 amp service that is 7.5 hours of consumption. On a 50 amp RV service it is 2.25 hours.

How often do you drive 100 miles in a day in your car?

Since this thread is about pickup trucks in an RV forum you need to consider the fact that a pickup will take much more energy to travel those 100 miles (they are heavier and less aerodynamic than current electric cars). If they are being used to pull a travel trailer or fifth wheel that will greatly increase the energy consumption per mile and the distance traveled will likely be greater than 100 miles.
Now you will need much more than 2.25 hours on a fifty amp RV service to charge that EV. That brings into play the fact that RV service wiring is not designed for maximum draw at each pedestal. National electrical codes allow for 7 50 amp service pedestals on a 200 amp service. That is slightly under a 60% load factor. The EV charging times you calculate use a continuous 100% load factor. Even 1 EV pickup truck charging for say 5 hours would likely overload that 200 amp service when all the other RVs on that loop are running air conditioners, microwaves, hot water heaters etc (i.e. using their allotted 60% load). And this doesn't even take into account the fact the RV attached to that EV truck will be using services as well, effectively putting 8 users on that 7 pedestal loop. There is going to be a lot of infrastructure changes needed on the local level to accommodate large Electric vehicles.

Well, certainly there will be infrastructure improvements. That's a given. And not just at campgrounds but at hotels as well. This is already underway. We won't stay at a hotel without an available destination charger. Hotel operators are well aware of this and are reacting accordingly. Campgrounds will do the same. Maybe add the infrastructure to support a second 50 amp service to 10 percent of the sites. 5 years later do it again.

But the reality is that the majority of EV's can adjust how much their charge current is. Those who are staying longer can simply charge at a lower rate as they don't need the speed. Power sharing is already common at many destination charger and DC fast charger sites. That's why at V2 150 KW Superchargers we use urinal rules. If someone is charging at a site don't park right beside him/her. Choose another site as the sites are paired and power shared. The first person connected gets the most power, the later arrival gets less. V3 250 KW Superchargers are not like this and are not affected much by the paired site being occupied. But there are still lots of first generation V2 Superchargers out there.

Cheers.
