How long have we got ??

They already are. Not only to energy suppliers provide a cheaper overnight tariff, but a recently charged battery offers a better range due to the thermal effects. It's win-win.
Overnight tariffs are only cheaper because there is lower demand. Once the demand rises due to an increase in overnight EV charging, the cost will rise too.Doofus said:

Overnight tariffs are only cheaper because there is lower demand. Once the demand rises due to an increase in overnight EV charging, the cost will rise too.But now we have a grid that has huge elements of wind as well as nuclear and in future that could include other elements like tidal and geothermal that can not be dispatched or operate at a optimal rate.
So we could have nights of massive over production with electricity prices going negative on occasions, as well as nights of of low production where we see higher prices.
But to make it blanket statement that higher demand will inevitably lead to higher prices is complete BS.

only if people are forced/successfully incentivised to charge at off peak times.
They already are. Not only to energy suppliers provide a cheaper overnight tariff, but a recently charged battery offers a better range due to the thermal effects. It's win-win.I guess if we go for a street lamp charger network - which in the overcrowded neighbourhoods I describe is likely to account for a lot of parking hence charging - then they can be smart controlled to charge off peak, or even instructed to drop out/slow down for a bit if the street/local supply reaches peak.
There's probably even scope to offer a tariff where you get a discount for allowing the grid to take a little energy back out to manage surges, on a "so long as it's full for 8am" deal.

No. There won’t be extension cords. And to be honest, nobody cares. You won’t have a choice, other than to relocate to somewhere with a driveway if you can or need. Fossil fuels will go, electric will replace. You are going public, transport, on a bike or by foot. Deal with it. Nobody is going to ask you - it’s just going to f
king happen. Why the hell do people think that the world is going to stop it’s enexorable march forward because they previously had an entitlement (insert whatever bullst agenda you want). Sort your st out.

I live in london , there isn't enough parking where I live , ( no off street parking at all) how will charging leccy cars work here ? will we have mile long extension leads all over the pavements/roads ?

Don't panic folks, the diesel powered sub-stations will kick in when we are getting low on electrickery.

Until there are enough electric cars and vans to cause overloads and power cuts ??
Or will smart metering save us at the expense of people being able to go about their business ..
Will sorry I'm late the car didn't charge soon become a common excuse ???
The average driver will need about 7kWh of energy per day. That's like running a hob for an hour. As you are probably aware people tend to run hobs during peak hours, and we don't suffer any supply problems.Or will smart metering save us at the expense of people being able to go about their business ..

As most cars are unused over night, that's when most will charge. As you have the whole night (say 10 hours) the power consumption would be many magnitudes lower than a hob.
The current grid will be fine with that. The only issue is if everyone wants to fast change at the same time as everyone is cooking their evening meal. The technology to manage that is simple.
The national grid have also said they don't see an issue.

Firstly, even 150-200 mile cars don't need charging everyday. They can be rapid charged once a week to meet most people's weekly needs.
Also, you can use streetlights, as many of them have extra capacity as the conversion to LED has massively reduced the electrical loading, or you can use bespoke kerbside solutions. Or a recessed channel for a power cable (least likely).
Sorry to disagree but LEDs give a better quality of light but existing street lighting is fairly efficient already. Our street has maybe one 35W sodium lamp per 10 houses, so not much to save and share around.Also, you can use streetlights, as many of them have extra capacity as the conversion to LED has massively reduced the electrical loading, or you can use bespoke kerbside solutions.

No, how much?
Here is a handy video telling you, short answer a lot, a crazy amount. Over 5,642,000,000 kwh a year. Now work out how many miles that would power electric cars for.https://www.youtube.com/watch?v=BQpX-9OyEr4

Massively hamstrung by the fact it's only supported by the second-class Chademo standard.
Unsure if and when we'll see CCS, supposedly 2025?
ISO 15118 is pretty settled now I think? Could potentially see vehicles implementing it this year. Wonder how many existing cars could be (software?) updated to handle itUnsure if and when we'll see CCS, supposedly 2025?
the home side kit is still chunky and expensive though.

Actually how it works in remote parts of Oz - https://thedriven.io/2018/12/14/diesel-charge-evs-... !!Octopus Energy are offering an EV tariff (GO) that offers really cheap (5p/kWh) energy for 4 hours overnight.
Starting to offer it over different start times, and that kind of thing will naturally get people to charge at those points in time.
For anyone considering Octopus, here's a code to share £100 - share.octopus.energy/loved-hawk-16 - msg me if you do & I am happy to donate half to a charity of your choice!
The sheer high cost of decent EVs, & fact that MANY people have nowhere to put a chargepoint, currently stops them going more mainstream, I would suggest.

At the moment if needed peak power is covered by gas fired generators.
These will rather rapidly be replaced by battery stations
At the moment Gas provides 40% of UK Power, Renewables 16%. These will rather rapidly be replaced by battery stations
Rapidly? Not so sure.
