EVCP remote from buildings

It might make more sense if the DNO provided another supply head on the car park side of the road, however if the road still belongs to the land owner, then it can still be adopted later with a concession  about access to the underground conduits or overhead lines or whatever, much as way leaveclasues in deeds work if there was a water pipe or private drains running under the road. 

So it can be done, and might be fine if the buildings are all to be rented not sold, but the possible problems are very much visible in the not too distant future - what happens if the cable for flat ones charge is damaged by the cable for flat 2 overheating, how is the cost shared, what happens if someone 'steals' power from the wrong charger etc.

Have you just been asked to lay ducts and install manholes and things or are you also supporting it all after it has been built ?

Mike.

PS of course the local authority may refuse to adopt if they are not happy with it, they are not obliged to, and this sort of thing may come into that decision.

Conveyancing and land law may also come into it (think about future maintenance, wayleaves, covenants and who gives permission etc.)

Would suggest this is really "landlord system", and I'm struggling to understand how this might work?

Hi Mike

The intention would be to install ducts around the pavement around a stopped up road ending up opposite the dwelling. The distance is one thing and running cables below ground that could be in separate ducts from each dwelling to the EVCP's and the safety issue of the EVCP proximity to each other - separate supplies. 

I would prefer to have the DNO provide a supply to the EVCP and then the access can be managed via the EVCP software and metered to the tenant accordingly. 

My main concern is from an electrical safety perspective and if there are any regulation or requirements that would preclude this from being installed? 

Thanks Graeme, but from a safety perspective are there any obvious issues? 

Simultaneous contact (as you mentioned)

Vehicle impact - really, you'd be wanting a more "street furniture" version of the EVSE.

Different risk profile (public access) - ought to be considered "on street" and many DNOs would not permit open-PEN devices at the moment for on-street.

Having said that about not using open-PEN, in terms of simultaneous contact (and to avoid the need for all the devices to be protected by open-PEN, given the fact that we have this wrangle with ownership etc, this is an area where you might (if the job really did get going) is it possible to consider all the vehicles sharing a common TT electrode near the charging bays, and thus avoid simultaneous contact?

I guess it would all need to be agreed on the legal side before you could decide some of these things?

Are there cable routes available at the correct (NJUG guidance) depths? Might be best to think about ducts rather than burying direct - because it would be easier for maintenance in the future, perhaps avoiding the need for excavation works to replace cables etc.

Private cables across even an adopted highway is certainly possible. One place where I used to work we had offices on opposite sides of a side-road and we ended up running ducting between the two so everyone could be on the same network (this was the days before VPN over public internet). I'm not saying it was easy - I gather there was a lot of paperwork with the local authority and lots of hoops to jump through - but definitely possible.

Likewise TTing the charge points, possibly with a common bond between them if they or the cars would be within reach of each other, sounds like a plausible answer to most of the technical problems.

Usually there's some way of restricting use of a charge point to the owner - some will be controllable by suitable apps that have to be paired through a suitable security procedure - or failing that just an isolator inside the house so the owner can keep it switched off until their car is parked there.

Won't disagree, but I've worked somewhere where they just put in a microwave link to achieve the same goal. But that's not without its "paperwork" either.

If this isn't done properly, somebody will trail an extension lead across the road. Trust me - I have driven over one already.
