Cont: Electric Vehicles II

I was at a camp site last year where the owner was complaining about EV owners trying to charge their cars from his electrical hook-ups. I wasn't even sure how they would do that because these hook-ups are neither 13A sockets nor type 2 connectors. And it was particularly mad at that place because there was a public ChargePlace Scotland DC charger only a couple of hundred yards from the camp site entrance.

I suppose if the site offered a 13A socket or the car owner had some sort of unusual adaptor they might get some juice. Me, I just ran the car's heating (all night) and my cooking requirements from the car battery, then recharged at the CPS charger before setting off the next morning
Yes, that is an important point - as an EV owner to realize that even if it's technically possible to connect to the socket, it might not be allowed or even safe.

For example the Schuko socket from what I understand are most often not tested for continuous use more than 2 hours or so.

Most camping sites in Sweden uses the https://en.wikipedia.org/wiki/IEC_60309#Blue_P+N+E,_6h socket, but still doesn't allow for charging an EV.

Ours are rated for continuous use at their actual rating (unlike the US- 80% of their rating for continuous use ie 1800W, but only 1500w continuous for a household outlet) or the Schuko (2 hours) limit... so our 2.4kw/10A or 3.6kw/15A granny chargers can be used in any powerpoint anywhere (my mums place, we had her caravan plugged in at christmas for the 'guest overflow' with our family get together- it was plugged into the powerpoint in the bathroom with the cord out the window lol)- anyone with an EV could have done the same with their granny charger lol- caravans use the standard 15A outlet (you can get 15A socket to 10A plug adapters if you need one- most caravan owners already have one) but most EV granny chargers dont need one

Those last are what are used at campsites in the UK, too. At least at Caravan Club sites, you're not allowed to plug your EV directly into them, but you can connect your granny charger with a 3-pin plug into your unit (caravan or motorhome, though the latter is unlikely) which in turn is plugged into the site's supply.

I would wonder if thats right though- most countries (including the UK) allow the use of 'tails' (similar to the 15A to 10A one I showed for our Aussie caravans) as long as they provide circuit protection- what rules specifically ban the charging of EV's from an outlet providing they have the appropriate level of protection??? (A quick scan through my (admittedly older) BS 7671 wouldn't rule out an appropriately rated and protected adapter... at least imho)

in the us, residential branch circuits for 15A and 20A breakers, the most common branch circuits, are required by code to have oversized wiring due to their continuous use and abuse by homeowners. the 80% for continuous use dictates the load cannot be more than 80% of the rating, and the conductors must be sized higher if that's the case. this is more of a guideline for dedicated branch circuits since, again, all 15A and 20A branch circuits already have oversized conductors

It's the rules of the Caravan Club. I'm guessing by insisting you plug in via your outfit, that takes care of the circuit protection.

What restrictions do you have when charging vehicles?



To ensure that you charge safely, we ask that you keep both habitation and car charging demand to a reasonable usage level and that you plug the car into a mains socket within your outfit using a mode 2 cable, not directly into the bollard.

Same here, a 10A outlet is required to have 2.5mm2 TPE here (rated at 24A exposed) minimum, however that is the minimum and the appropriate sized cable for the job should be used (ie buried, or long lengths require a larger sized cable according to the regs tables), however what I was talking about was that our Aussie powerpoints (outlets) can carry a full 10A/2400w for the 10A version indefinitely (same for the 15A etc)- no derating is required for longterm usage loads ie what you see on the label is what you get... (the breaker for a 10A powerpoint circuit is 20A, so is always below the current carrying capabilities of the cabling... the powerpoint itself is also rated at 24A or more for the connections on the plug/socket although they are only 'legal' for 10A... )
 
It's the rules of the Caravan Club. I'm guessing by insisting you plug in via your outfit, that takes care of the circuit protection.
So thats a 'company rules' not an actual regulation in other words... ie not enforceable by law- a caravan park not owned/operated by them would not be required to follow 'their code'...

I didn't suggest otherwise. It's enforceable by the Caravan Club. They can take action if you don't comply, e.g. ask you to stop, cancel your booking, cancel your membership, prevent you from staying at their sites, etc.

Which has no bearing about availability of charging using caravan parks (which is a common source of EV charging in smaller country towns here btw)- you just can't use THEIR caravan parks...
Many businesses have rules particular to them, but that doesn't make it a rule that you have to obey everywhere...
In the UK you might need a tail/adapter , here you don't even need that- the 'granny charger' supplied with the car can be plugged straight in even lol

I'm not seeing how it's not relevant, given how the discussion started.

The Camping and Caravan Club has similar rules, so that's the two main operators of sites in the UK who have the rule. As they say, other sites may have different rules, but their wording suggests there are technical reasons for the restriction, even if it's physically possible to plug in directly.


Can I charge my electric vehicle (EV) on a Club Site pitch?

At this time the Club allows you to charge an EV on a pitch, whether it’s a car or a light mobility scooter. However, you must not charge your vehicle directly from the site’s electric hook-up bollard as it was not designed for this. The relevant standards state the bollard should only be used to provide power to leisure accommodation via a single 25m long lead. Once your caravan or motorhome is connected to the bollard you can trickle charge the vehicle’s battery from a three-pin 13A socket in or on the caravan or motorhome.
Some other site operators (including those on the Certified Sites (CS) network) may operate differently so please ask on arrival.
 
I think this will gradually change as more and more vehicles are electric and site operators upgrade their facilities in line with demand.

Yes, indeed. The Caravan Club are adding charging points at some of their sites. (Not an issue for us, yet, our motorhome is diesel, our only non-EV.)

There's no obvious reason you couldn't charge a car directly from a campsite 16 amp CEE17 outlet, but I can understand caravan site owners wanting people to charge indirectly from an outlet on their caravan instead. Perhaps to limit the current draw a bit (from 16A to 13A) but also because it means the user will be charging via their own 13A fused plug, so that protection would blow first, before the site's 16A outlet's protection does, making it the user's problem.

While the site's infrastructure will be built so that any pitch with a 16A outlet can safely draw 16A continuously, I presume there's a limit to the number of pitches which can simultaneously do that.

From the quoted part of Zooterkin's post: "The relevant standards state the bollard should only be used to provide power to leisure accommodation via a single 25m long lead."

That to me sounds like there is a standard that covers their use on a caravan park, a standard that was probably put in place before anything like widespread adoptions of EVs. Standards tend to lag behind technology,.

The RV parks and camp sites were never intended to handle charging for EVs. Even if the infrastructure of the RV park can handle it, the park should be able to bill the customer. Average utility price for 100KWh in the US is $16.54. It very well could be a big surprise to a small RV park that they have an electricity bill hundreds of dollars more than they expect.

Full circle back to what I first said lol- most do charge a nominal fee here if you are charging an EV here (usually $10) but it really is a 'emergency topup' situation as you are only using a 3.6kw charge rate charger after all (and it would really only be in some 'wide spot in the road' that you would need to, as chargers here are so common....

After all, even my little town in rural Queensland (all 1500 of us) in the middle of nowhere has a EV charger here now and drive to any of the three 'nearby' towns (an hours drive away mind you) and between them there's another seven or so chargers available...

If we Aussies can do it in a country the size of the US, but with a population only a third of the UK's, I can't se why other countries are finding it so difficult...

No, it's not difficult. But I do see how it is possibly abused. My guess is most campsites in the US have addressed this in some way by now.
 
All I know about electric hook-ups in Scottish camp sites is that you pay extra for the pitch to use the electricity. I don't know if they ALSO charge you for the electricity you use. If not, presumably some average use is factored into the flat-rate payment, which could certainly upset a site manager if campers suddenly started pouring kwh into a car battery all night.

In the US. At least how they typically charged at State and National Park campsites, it was a fee depending on the type of campsite. One with an AC hookup and one without. I never saw a anything that charged for how much electricity you used. There are also a lot of private campsites like KOA. But I have never used any of those.
