you may as well just order a nice big diesel generator and fuel bowser then to charge your EVs
order NOW off Ebay and you should have them delivered in time for the 2030 deadline  ;D
That's not a bad way to launder red diesel for road use. ;)

I'll check next time I'm over, but get a feeling Mum's 3 Phase supply is also 100A.

That would explain why the streetlights dim when her (electric) boiler fires up ;D
100A service head is standard , but many are down-rated to 60 or 80 amp HRC fuse internally  ;)

Also, didn't the DNO (distribution network operator) aka electric board  :P insist on hazardous location and explosion proof electrical fittings being used at your location following the "incident "  :D
Bicester has a new eco town, supposedly set up with public transport and set up for EVs.  The buses, well, their frequency and reliability is predictable, but the feeds are all 60A*, so hardly ideal for them charging EVs...   ...though as Kevin Wood says, if everyone plugged in, the local substation equipment would let out all of the magic smoke.


*According the the sensationalist media, so obviously no idea if that's the feed or just a small fuse.

A mate of mine has a 60A incomer and is an ECO type so has an EV, heat pump, solar, giant bomb LiPo battery, the works.
His main fuse keeps going pop. He's requested a bigger one but the DNO are dragging their heels while they decide if he can have one. ;D

.. but bad things would happen if everyone decided to draw 100A 24/7.

The local cafe, which I walked past1 on my way back from the dentists this morning.

1. This may not be considered factually correct


Fast forward a few hours and I go there with Mrs KW for lunch and they grass me up for having a bacon butty in there earlier. :o
They need to read up on GDPR and client confidentiality. I will be armed with an NDA for them to sign next time! >:(

.. and then there's the heat pumps we're all told we'll need when they ban gas boilers. ;D

Maths was based on the following...

(square root of 3)1.73 x 32A x 240V = 13,286.4Wh or 13.29kWh

So to charge 93kW would take 7 hours.

22kWh would require a current of 53A which is somewhat optimistic for a domestic supply, even three phase.

Why root 3? The correction you're applying is already accounted for in the 240V RMS calculation of voltage.

Most normal houses only have single phase, and the supply is typically fused at 60A. Flats can be 30A, but if you're living in a flat on the 12th floor of Nelson Mandela house then charging an EV is going to be problematic anyway. You can ask for the 30A/60A to be upgraded to 80A or 100A on a single phase.

A 22Kw wall charger does require 3 phase. Again you can ask to be upgraded. I suspect the local distribution grid is going to struggle though if/when every house in a street wants it.

root 3 is used for 3 phase power calcs as you don't actually get '3' times the power when its a 3 phase machine in delta wiring (you can in star but then the voltage is lower), but the voltage is 400 not 230  :y

Yes, I know, that's why I said the root 3 bit is already taken into account in the 240V RMS. 400V / root(3) = 230.9V.

It's all irrelevant because the diversity used in sizing the substation that feeds your housing estate means it'll soon explode if every property draws 22 kW for most of the night. ;D

It was awkward enough planning fuel stops when I had LPG, but at least I had a tank of petrol to fall back on then.

I was almost half tempted to get a 2nd hand EV for commuting only back when leccy was a sensible price, given that most will handle my 50 mile commute and charging at home would be no problem.

You'd need your head examined if even considering one nowadays. :o

cook everything and eat it all if it's still cold or part thawed  :)
anything you can't eat ,it's all cooked then , so freeze it
assuring you have a working freezer  :-\ and just did a "Turbs" turned it off by accident :P

I don't think I closed the door properly last night.   :-\  :-[

So not only have I lost a lot of food, it's probably been running like the clappers ever since trying to keep the temp down and my next leccy bill will bankrupt me!  :-\   :o   :(

In that case, you can freeze the stuff down relatively quickly, it's only been warming up for sub-24h, and has spent most of that time frozen anyway I'd re-freeze it, myself. Just make a mental note that it needs cooking immediately, and thoroughly, when it's next thawed.

Is the SD OK?  And the standard one supplied is quite small (but plenty big enough for UK and a few other countries at the same time).  I haven't worked out yet how its locked to the car (presumably just an encrypted file with VIN etc).

I know you can copy the files to another SD, and that still works.  I have shit load of 64GB cards, which easily allows all of Europe, so I copied my files to one of them, and then plugged that into the PC, and allowed it to download all European maps, and thats what we use.

I can post you one with our files on if you want a go at cracking how its locked to the car, but I have no idea what will happen if you get it wrong - presumably all Nav and all Jaguar Voice stuff will stop working until it sees a card that is locked to it.

Yes, I copied everything to a larger card ages ago on Mr. DTM's advice as I think they wear the cards by using them as swap. ::) Copied card works fine in the car, but the upgrade software just barfs when I present either card to it. :(

Oh I don't know.... My estimation of William has gone up somewhat in the last few days.  :)
Nah, as the older sibling, he should have properly sorted out Harold with a good ol' bit of fisty cuffs every weekend.  Its what brothers do.

You forgot the bit about charging up capacitors with a 500V megger and leaving them in their toy box... or was that just me? >:D

Not had any issues with hers, but hers is the poor mans version (DTM will know the exact designation) that you plug the SD into a computer.  I'm guessing yours is the OTA update version?

No, mine is the same, SD card that you update in a PC in theory.

Don't try and use it in Cornwall, is my advice. ;D

.. although I suppose it might be that the road designations are better with an up to date map.

From memory jaguar use Tandy electronics from 1972 for their satnav.

I'd be tempted to update the maps in mine if :
a) The update software didn't just bomb out with an error every time I try to do it
b) It was capable of sending me down roads that don't have grass growing down the middle. Maybe mine has the mud-plugging Land Rover version installed by mistake?

That kind of budget will undoubtedly reek of corruption, so some people are pocketing an absolute fortune.
It was mentioned on the news recently that the NHS were paying agencies up to £6k per shift :o for consultants, so yes, I'd be looking at where that money's going for a start.

I suspect that, if we spent a small proportion of that budget on providing a basic level of social care for those being discharged from hospital, the problem would go away. We don't provide this in a cost effective way, so we end up providing it in the most inefficient way possible, in a much needed hospital bed/corridor. ::)
