:doh:
I should have heeded the words or Mark Twain
“Never argue with an idiot. They will drag you down to their level and beat you with experience.”
OK so I can see I am going to have to break this down into really simple terms. I have had to go back and see where you even came up with this 6.2Gw figure from
Oh and BTW it makes this ...
No such thing as a 60kw battery or even a 60kW battery :bang::bang:
You clearly have no idea of the units and quantities involved.
absolutely priceless.
Honestly I hope your bosses are not watching this and I hope I never have to fly a plane where you've had anything to do with designing the power management.
So.... [rolls sleeves up]
60KW, - 60KWh you knew exactly what I meant, typo on a phone screen maybe even auto-correct who knows what ever the priceless thing about it is the 'h' relates to 't' time which is what I keep telling you to factor into your calculations, but you cannot see your mistake.
lets look at where you got your 6.2GW number from by looking at the article, which until now I had not read but once I did, my god did I have a good laugh.
Don't complain about my accurate calculations when it is you who are pulling "millions" out of thin air.
This may come back to haunt you here.
the article
https://www.nationalgrid.com/stories/journey-to-net-zero/5-myths-about-electric-vehicles-busted
Enough capacity exists
With the first of these, the energy element, the most demand for electricity we’ve had in recent years in the UK was for 62GW in 2002. Since then, due to improved energy efficiency such as the installation of solar panels, the nation’s peak demand has fallen by roughly 16 per cent. Even if the impossible happened and we all switched to EVs overnight, we think demand would only increase by around 10 per cent. So we’d still be using less power as a nation than we did in 2002 and this is well within the range of manageable load fluctuation.
so at some unspecified point in 2002, the national grid experienced a peek (instantaneous demand) for power of 62GW that is to say at a single moment 62GW of power where being drawn from the grid. this is not GWh, this is instantaneous power consumption (keep reading I will explain)
There is then no link drawn to say that if the peak demand raised by 10% that would power all the electric cars in the UK, 6.2 would be a figure you plucked out of thin air making a very random assumption.
Now assuming there was something like 6.2GW increase in demand across the whole UK this is not 6.2GWh, this is 6.2GW per second,
that's is for anyone bored enough to read this 1 watt = 1joule per second, If you plugged in 30million electric cars for 1 second no you're not going to get very far there is going to be a big bang somewhere (think ALF the tv series from the 80s).
But as you pointed out above car batteries are not 60kW they are 60kW/h
so all your maths is being based on 6.2GW per second, not per hour
6GW is basically the output of 6 x Chernobyl reactor four (the one which blew up) sized nuclear reactors being turned on all in 1 second.
It is also about the same amount of power you'd get from one large inshore wind turbine in a year, or a couple of smaller ones.
So if demand went up by 6.2GW that is not per hour that is per second there are a lot of seconds in a year.
The mistake I made here was being lead by your ridiculous math's.
The final point here is that article does not say anything about demand increasing by 6.2GW/s it says peak demand in 2002 reached 62GW, and that they expect if every single car in the UK changed to electric power in an instant over night which would be impossible. then they would expect the demand on the grid to increase by 10% that is to say there is a certain demand placed on the national grid each year and it does not state not an increase on demand of 6.2GW in a single second, and it is taking into account that cars don't charge rate there range in KW/s. OK so 6.2GW is not going to charge "millions" of cars at once, but is ample to keep millions of cars charged in the course of the year.
But that's not what the article says. The article talks about an increase of demand on the entire network in the course of a year if demand increase 10% something like over 300TWh (2014 figure) per year, then the grid could cope.
How many electric cars can you charge on 30TWh per Year ?? oh and that was 300TW used we wasted about 35TW in losses across the network.
just to reiterate your point
You clearly have no idea of the units and quantities involved.
oh and ---> :bang::bang:
Go get busy with that little calculator of yours.
