Another summertime issue in many campgrounds is sure to be that EV charging may preempt the ability of others to operate their air conditioning… As temperatures rise to to 100’s (uh-o :( !!), this is sure to test the mental metal of otherwise friendly fee-paying for services campers…

3 tons - mostly (happily!) :) off-the-grid…

I read this twice and I’m not sure I understand. Why would using an RV pedestal to charge a car pre-empt someone else on another site from running an AC? Maybe I misunderstood this.

Because there is a finite capacity in campground wiring, in most cases installed prior to today where everyone has to have a huge monster of an RV with 2 or 3 air conditioners, heat pumps, electric clothes dryers etc.

The vast majority of places I have been have had issues such as low voltage on crowded weekends etc.

Ah ok. I don’t know though. We drove a pusher for 18 years. On hot days with the various systems running that sucker gobbled up the electrons.

When we charge in a campground we are almost always on a 30 amp site. Our car can’t pull more than 24 amps. Literally can’t trip the breaker. But our little trailer can. Between AC, hot water, fridge, converter, microwave etc etc. Easy to pop the breaker. And if the voltage drops the trailer just pulls harder. The car automatically current limits to 18 or 12 amps if the voltage drops to 111 ish volts.

Jmho. Not an expert.
