perspicacious:
There are 4 charging points! Infrastructure requirements should have been, by now, solidly embedded in building regulations and planning.
And how much would your area DNO charge to supply 2 MVA or more? What % of the build cost would this be?

Early adopters may not care, those of us in the second tier who like to buy a five year old car and run it for another ten may be a different story.
perspicacious:
Why 2MVA? That's 5 kVA or 20-odd amps per car for every single one of them.
Isn't 2MVA a bit of an over estimated for 4 charging points
I responded to the concern that only 1% of the spaces had EV charging facility.
If 50% were deemed an acceptable level and the expectation of a full charge on a 85 kWh pack in 2 hours suggests a 50 kVA charger at least, which in turn suggests 1 MVA.
And that is on today's expectations when I would have thought that the infrastructure would have at least a 10 year expectation of meeting demand. If it only doubles in use, that's your 2 MVA.
Factor in that there's already a 120 kW charge point near Tower Bridge, the discussion regarding low usage/city centre/demand etc takes a different angle.

. all this talk of hundreds of public charging points being needed in car parks during the day, demanding masses of power at times of peak demand … really getting tedious.. for those that need to charge up, a trickle charge over the 8 hour work period would be adequate.. the other 90% like myself would have charged overnight, on cheap electricity, and waking up to a full tank that will suffice for a number of days.. I have had my EV for over a year.. times I have needed to use a public charger … not once.. EV`s .. it`s not Armageddon.. just a slow slide into normality.. fossil fuel car production.. ok, thats Armageddon
gary..
Concerning separation of different earthing systems: is it permissible to place an earth rod close to the DNO's service cable? I cannot see how they would interfere with each other except in the event of damage to the latter.
