Is it possible for a motorhome to hook up to electric car charging points?

[MisterB]

i dont need to do, but am interested to find out if it is possible to hook up to the electric car charging points to recharge batteries?

Has anyone ever done it, thought of it or carried out any research as to its possibility?

 

[Nixdorfer]

Think someone asked this sort of question a while back.

The answer seemed to be no, the voltage is a lot higher so you would a way of dropping it to 240v so not worth the expense

 

[Figaro]

I think you'd be rather unpopular if Mr Tesla turned up and couldn't get a charge as a motorhome was in the bay.
I'd guess you'd need the app thingy to access it, and cobble together a suitable cable for connection, then the computer would say no, not a recognised battery and on board computer.
So to summerise, I think the answer is no.
Others may have a more technical answer.

 

[MisterB]

thanks for your answers, however i was asking if it could be done, not if anyone thinks it could be done or reasons why it might make other users unhappy.

i will do some digging in the forum to look at previous discussions

Yes it could be done

There are alternatives, many sites and Farmers fields have Pylons

Street lights? Telephone boxes if there are any left.

There are some chargers out there with 'commando' type connectors but they are very few and far between. Those with CCS, CHADEMO or Mennekes connectors you won't be able to use as there is a two way data communication between the vehicle and the charging point that allows electricity to flow.
It would be an interesting experiment to plug in a MH into a 150kW charger - a lot of fireworks and smoke I would imagine.

? you have sussed it, me thinks phone boxes might be the answer ther'e already low voltage

Used to have a tenant in my house, we had a phone box outside the gate, he had both the phone and electric wired up to the house.

I think THE CURE would be better!!??

How? The charger communicates with the car in order to determine maximum power transfer and voltage. The feed is then adjusted to match the maximum that the car or charger can deliver. Towards the end of charging the car requests a reduction in power, same as BMS system charging Lithium batteries.

Once saw a VW e-golf plugged into a Tesla charger and after 10 minutes he'd received no power and had to move to the Ecotricity charger.

Tesla Rapids will only charge Teslas. Tesla Destination Chargers will charge other vehicles but only at 7kW.
You can only charge via 13amp and commando type chargers, anything else isn't going to work.
(PS. I have a BMW i3)

I think you might need an account to use vehicle charge points, most I have seen appear to have some form of card readers attached to them.

Yes, those that are on the machines in car parks and motorway services require an app or an RFID to start the process. The wall boxes generally don't but only ones with a 13amp socket or commando connector will potentially give 'free' electricity.

Agree, but the charger still communicates with the vehicle to agree charging rate. A destination charger will charge at a higher rate if it's on a 3 phase supply and the car can take the charge rate.

Hence my answer

Yes it could be done

It "could" be done.

Pointless saying that its difficult, complicated or feasible, let alone suggesting that payment would be a massive issue

Also to be fair not all electric vehicle charging points are sophisticated as some, looking at the points that manufactures keep mailing to us, encouraging us to install them on our campsite.

 

[Oldbob]

Pull up in town, out with the step ladder and plug into one of the Christmas tree lights points.
All are 16 amp blue sockets around these parts.

Yes of course it could be done.

 

[ceejayt]

There are plenty of three pin plug chargers out there. No special connection required but you would need the RGID or app to start the charge. Can’t see it would be a problem.

 

[tacr2man]

You would need a decent battery bank , or it call be over in 94 seconds ?

 

[MisterB]

Thanks for the responses.

When there were such things there was a mains supply to the lights. The phone mechanism didn't require power as such.

Three pin would be fine

you need a 2.70k resistor on the cp pin to pe then put a 1.3k parallel on a switch to start charging,take your live from L1 for your 240v on board charger.

 

[Paul Wilkins]

I certainly wouldn’t try it. I own a BMWi3. There is a lot of communication between the car and the charger before electricity starts to flow. Unless your hooking up to at 13amp plug or a commando socket, I’d steer well clear.

 

[buzzb]

useful info for motorhomes,imagine when there are charge points everywhere you just happens to be next to one,EHU especially in winters.

Don't you think that motorhomes have enough bad press already MB.
