I found this article that explains that Smart Meters can be used to switch EV's (and other devices) off:  https://oilprice.com/Latest-Energy-News/World-News/UK-Energy-Firms-Could-Switch-Off-EV-Chargers-As-Demand-Peaks.html and this is the Government plan that is the link within it: https://www.dcusa.co.uk/wp-content/uploads/2020/07/DCP-371_Last-resort-arrangements-for-Distributors-to-manage-specific-consumer-connected-devices.pdf  Share this post Link to post Share on other sites Share this content via...

So there wouldn't be a massive peak evening demand, the charging demand comes through the middle of the night, but it is spread out over many hours depending upon the charging profile.  That depend on the charger being used as well as the person using it. They won't do that be default, they'll just start charging as soon as they're plugged in, at a fair rate.  They can be set to charge overnight, but it's down to individual users, if they don't have the right energy tariff they won't bother. Large spikes in demand are inevitable with large-scale EV use, to change that the government would have to mandate specific charge times and have some way of enforcing that.

whiteowl   54 #15 Posted October 11, 2020 My smart meter is at the source. It has no idea whether I'm running a hairdrier or a vehicle charger. Both of which will be (more than likely) on the ring main.  Even if they weren't, they'd be on separate fuses and my smart meter is nowhere near those.

Exactly! But before everybody thinks all is OK, the most optimistic view of those pushing the current version of smart meters say they will last for 15 years without replacement. Many doubt this, and cite a number of reasons.  As the Government is behind the "Smart" meter project and says we can all opt not to have one (see Ofgem on this), the pages I cite suggest that will change shortly. It follows that it is highly unlikely that they would allow people with smart meters to go back to non-smart meters.  If I had an electric car, I would certainly be doing all I could to avoid having a "smart" meter!  Share this post Link to post Share on other sites Share this content via...
