Guy rang me yesterday, He wants to plug his EV in and charge it overnight at his static caravan. He only has a 2OA supply: that's fine he can in theory plug in via a 13A socket and trickle charge. What he wants/needs is some sort of management system that will turn off his charger if he turns on say kettle and toaster first thing; I don't even know if this sort of thing is available, I would think it would have to be installed at the CU and won't be cheap. I think I'm going to tell him he needs to speak to a registered EV point installer, as (before I even look) there's probably all sorts of issues here with liability, and additional earthing requirement/ RCD issues, but any thoughts? It''s an interesting and not unreasonable question, and i guess likely to be commonplace in the future. You have a static: how do you charge your car when you're there?
Our units are often used on garage type boards for switching off individual loads, if the full load of the garage supply reaches 40amps for instance then we isolate whatever load runs through the contactor. We could programme the CT for a maximum of 20amps and whatever runs through the contactor will be isolated if 20amps on the incommer is reached until the supply falls below 20amps. We use this product a lot with EV Chargers and have not heard of a car charger yet that does not restart on power loss. The units come with over and under voltage protection and the controlled circuit can have an MCB, Type A RCBO or even a full Type B RCCB, of course you can have no circuit protection or indeed have an IP65 Version, you pay your money you take your choice.
As an example of pricing, a double pole MCB integrated unit would cost £152.50 ex VAT ex Carriage.
