I think that is a rare case of the government being proactive for a change rather than reactive. This might be pressure from EV manufactuerers to make sure the grid/peoples homes can cope when we all switch to electric but I dont know. I agree its unlikly that all the half a million cars will start at the same time anyway but I think they are just trying to stop it causing problems on the off chance it happens. If Octopus have say 50,000 customers and they all go onto IO then when they try to start charging at 11:30 thats a big hit for the grid to take. Okay the fact the cars are distributed across the country helps make less of an impact than pulling it all from one place, and its just a random example. But when we're all electric, where there are millions of EVs on the roads the impact will be massive.Walter Eagle wrote: ↑Wed Aug 23, 2023 11:33 amif everyones cars start charging at 11:30 pmIf they all stop charging at the same timeWell, yes, yes and yes. But I really can't see these three conditions being met.if they all go on charge at the same time
If we take the half-million EVs you mention, what are the probabilities governing the start times and durations of their charging periods? I genuinely don't know. There may indeed be a general long-term pattern but I'd suspect it's not precise and specific. Adding a random time factor on top of this could just as well serve to produce coincidences of starting that were not there to begin with.
You mention IT. This delay is not like CSMA/CD. In that case we do have an identical starting time for two events. Holding off for two randomly generated delays ensures that the coincidence doesn't repeat.
Out of interest, does your domestic charger randomly delay charging? Mine doesn't, and it's only a year old. Is this delay issue only emerging now and is it being enforced by legislation? I've not come across it before, so I'm genuinely interested in understanding what the future holds.
I have a Zappi v2.1, it was purchased and installed in October 2022 and it does have a random time delay. I can however manually over ride it. I cant remember if the other option I had was a Zappi v1.0 or v2.0 but the v2.1 was cheaper. I dont know if the smart regulations came in on the 2.0 or the 2.1 There is a lot more details here on how it all works here.
