My wish list is modest, a 240v electrical connection in public campsites.
Works great when there are 3 EVs in a 200 site park and you can have it now by getting a 50amp site.
But for wide scale EV usage...If you've ever been to a park on a hot summer weekend when everyone is running their air/con, you know that power goes out regularly.
Your average draw for air/con is usually around 11-12amp (single air/con on 30amp) or 22-24amp (dual air/con on 50amp sites).
Now imagine adding in 100 sites with EVs pulling the max amperage to charge up big battery packs regardless of the weather and run the numbers...and don't tell us how you can reduce the draw by setting it lower...you and I both know people will use as much as they can get away with until there are outages and even then, if they want to travel the next day, they will continue to bump up against those limits causing outages.
One of the parks we stay at has trouble on peak summer weekends (we bring our generator to account for this). Owner found out it was going to be upwards of $50k to upgrade his power feed to fix the problem. This didn't include rewiring the entire camp just the feed from the road to his main distribution panel. To add in EV charging at most sites, you would have to get an even bigger feed upgrade at even higher price. I'm betting you wouldn't be the first to step up and pay for it when most don't need it.
Meh. People find problems where there aren’t energy. People driving EV’s are not evil. They just like the driving experience, performance, convenience. Most will obey the rules just like most people do. The campground director can simply say charging at designated sites only etc. Not a big deal now, won’t be then.
He actually has a logical point. It is not a big deal now because there are so few out there. But imagine half of the people in a 100 site park needing to charge for the night. They would either have to wait their turn and switch out during the night or upgrade the camp wiring along with the utility wiring from the power plant to the camp for the amount of energy required. It may also require additional substations depending on how far it is to push that much electricity to places far from the power plant.
It is a valid concern Shiner but as you and I have discussed infrastructure is not static. Adding a half dozen J1772 32 amp Level 2 locations would probably suffice for the next couple decades and would be compatible with every EV. Probably just get a company like ChargePoint to put them in and then just share the profit. Maybe do it modular. A couple at first, a couple more when they get busy etc. ChargePoint is good at that kind of thing. I noticed on one of my appraisal trips that one of the campgrounds near Kelowna put a clipper creek 40 amp unit in last year. Probably the first campground close to us with a permanent J1772. We were invited to use it for the hour or so we were there visiting. Like 40 km from our house. Never knew it was there. :) It is on the map though.
