    No, you maintain state that the grid couldn't cope with 2m EV's without smart charging & then reference a report stating that 'charging must be smart to accomodate 15m-plus EV's' ... you'll note that both statements relate to EVs & smart-charging !!

    And as seen from other posts, the charging is 'smart', at least the EV owners are. So looks like the 2m claim was .... what's a polite way of putting it ..... ill-informed, perhaps bloke down the pub said, or the office equivalent, my colleagues told me that ........

    Apologies for the pedantry, but it didn't actually say smart charging was needed, just that we couldn't assume EV owners would avoid peak time: ..
    Hi

    The comment wasn't aimed at what the report/presentation supposedly said, or what commentary exists in articles, it simply referenced two points which were made which don't even support each other ...

    Looking at the source material (https://www.auroraer.com/) the relevant information (P15) simply points at a point in time (2035) where EV market saturation in the UK has reached 10 million vehicles, at which point the required additional daily demand profile has been assessed with no EVs, EVs & EVs with smart-charging technologies. The conclusion is that without smart-charging EVs would add ~3GW to peak evening demand, reducing to 0.5GW with smart-chargers shifting demand until off-peak hours when it would add ~7GW to average overnight demand ...

    That's about it really 0.5GW if smart-chargers are used, that's around 1% of current capacity, not far from the average reduction in demand for the past 10 years ... apart from that, HM Government are already scoping the legislative requirements for public charge points and at the moment it looks like they'll all need to be smart-technology enabled (link) , with the relevant bill at report stage next Monday (29/01) ... as such, considering the timeline/timescales involved, argument on infrastructure capacity grounds related to smart-charging can only be considered as being insignificant, therefore simply diversionary ...

    Big investments into EV's by the car manufacturers, though Toyota's 'opinion' is still interesting.

    .Smart chargers are slightly behind EVs, but really not very far. They can easily be deployed in the big, hungry multi rapid charger sites, before trickling down to residential

    Just curious but what would the point of a smart charger being installed at a rapid charging site? Presumably if a person were to plug into one of these sites they need the car charging rapidly now, not when the grid gets a bit quieter?

    Delivering energy over a longer timescale isn't really a new concept to anyone seriously looking to be as clean energy-efficient as possible and leverage self generation

    I know. But David asked why we all wouldn't just use 3 pin overnight. I was explaining that it's inefficient and inconvenient compared to a proper charger, and there are only a few uses (that we have identified) where it would be preferable.
    Bloody hell fire. Are you lot still at it?

    People are claiming that there's no such thing as solar power in the UK, and that fridges will turn off, so there's some serious rubbish being posted!

    Good question. It's not a matter of charging quickly or slowly, just how quickly. You could turn up to a site with 4x 100KW chargers. You turn up, charge at 100kW. Someone parks beside you, you both charge at 100kW. A third person turns up, that's 3x100kW. If a 4th person turns up and plugs in, maybe you all go to 90kW - that's 360kW total. Maybe the ad break comes on in Coronation St and everyone wants to use their kettles. You all get knocked down to 80kW.
    In my totally made up example, the SLOWEST anyone charges at is 80kW! That's still really fast compared to the 50kW that most of us are used to, at best, at the moment, superchargers excepted.

    Obviously the Daimler bloke doesn' think there's going to be much of a market for battery electric vehicles.

    Just to say that the EST in conjunction with fully Charged and Robert LLewellyn, have done a series of short films on EV's (5 I think, intro and 4 parts), here's the first:

    I'm sure that's a totally unbiased warts-and-all series, with absolutely no preconceived conclusions.
