    AFAIK all current (ha ha) electric cars have a timed charging function.

    Thanks, that's quite positive, something to get amped up about, pop in my knowledge battery and use to fight the 'resistance'. ;)

    That's quite different to the claims (on here) that the Grid couldn't cope with 2m EV's.

    The claim was that grid couldn't cope with 1m EV's without smart charging. The number was increased to 2m when the anomaly in the assumed average daily consumption was pointed out.

    That's without smart charging

    The Aurora report quoted stresses that charging must be smart to accomodate 15m-plus EV's.
    “There are many scare stories out there suggesting our power system cannot cope with the growth in electric vehicles. On the contrary, our research suggests that, provided EV charging is smart, the GB power system can easily accommodate 15m-plus electric cars,” said Richard Howard, head of research at Aurora."

    Hi

    That's pretty odd ... are you saying that your own 2million EV guess is correct or the 15million in the referenced report ?! .. :think:

    As the two statements refer to different scenarios, one without smart charging and one with, they could both be correct.

    I'm getting a myernergi Zappi smart charger in March. It acts similarly to the Immersun immersion heater electricity diverter but for the car.
    Hi

    That's why I believe that the arguments made by many who argue against the viability of EVs are simply repeating the strategy previously used against solar PV, wind power & any other form of change which is raised - treat every change/technology on a stand-alone basis & only argue the known weak-points ... a conspiracy theorist could easily assume that there was some form of vested interest behind it all !

    Anyway, if your vehicle, and millions like it, can take most (/a good proportion) of it's energy from the demand side, the overall load on the grid is significantly reduced ... add to this supply side energy which is generated on a distributed basis (ie local DNO connected solar farms & turbines) then the load on NG infrastructure is further reduced. National Grid seem to recognise this as being a major factor in not having to significantly upgrade their infrastructure and seem to be concentrating more on automated balancing of a more highly distributed generating infrastructure!

    Hi

    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 !!

    As being discussed over the last few pages, where do the 900k homes with demand side generation fit into your scenarios? ... there aren't many people involved in this 'conversation' on EVs, but it seems that the majority you're arguing the point against actually have EVs and/or demand-side generation, so I don't really know what you're attempting to convey.

    What needs to be understood is that the way electricity is generated & distributed is changing from a totally centralised model to one which is diverse & distributed. The HV national grid is evolving from a network of delivery to one mainly concerned with balancing - there are already plenty of sites generating electricity directly to the DNO managed local grid, just for example we have three 5MWp sites within a half-hour walk from the front door, so it'd be pretty certain where the majority of the daytime power in the locality comes from! ...

    Unless, of course, someone really wants to utilise & leverage their own microgeneration source to provide as much of their own clean/green energy as possible, so keeping the current low would be an advantage ..
    .

    Yep, already mentioned this to David in a previous post, charging slowly ON PURPOSE - my Dad does this (when it's sunny!).

    Arguing that the grid can't cope with 'x' electric cars without smart chargers is a non-starter for me. EVs are a 'coming' technology. Smart chargers are a 'coming' technology. 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.
    It's being presented as a problem, but the problem has already been (or at worst, is being) solved.

    Hi

    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, after-all, proportional diversion to DHW & 1kW kettles seems to be pretty common in homes with solar PV! ...

    ... and on that point, it's time for a cuppa! ... :coffee:

    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:
    He said the extra peak demand in a smart world was an insignificant increase, but it could not be taken for granted that motorists would change their habits.

    So, in a way, he's saying it would be fine if people did the sensible thing, and if there was an incentive, which of course there already is via E7. From the EV owner comments on here, most already seem 'smart', and as I expressed previously, on these kind of scales, 2m, 15m, 30m .... we are safe to use averages.

    I suspect the need for smart charging is to add a stick to the existing carrot, and that seems relatively sensible, belt and braces and so on.
