For V2X

https://www.gov.uk/government/news/new- ... 000-a-year

The people who set the technical standards for CCS are, albeit slowly, working towards V2G. It will be this thar enables using the EV battery as a house battery and not the government. Chaedomo already allows V2G for Nissan Leafs and others.

The talk of savings of £1,000 pa are pie in the sky for those already on TOU tariffs.

Yup, govt ollox tweaked & massaged for maximum "we're so good to you" hyperbole.

"but we have papers & numbers" (liberally coated in snake oil) ..yeah, reminds me of an Alexei Sayle's "stuff" clip using Neville Chamberlain's "peace in our time / I have have in my hand a piece of paper" quote about hitler accidentally giving him paper he wiped his backside on .. but couldn't find a clip.

Given the cost of buying, installing an ev charger, (*maybe* also requiring a smart meter) joe pyblic may look at £1000 or more ...then tariff & time jiggling & optimisung charging, ..many years payback If it lasts fault free, akin to our chat on solar farm investment payback versus wind turbines *if* money was all we gave a damn about.

20 odd years wasn't it!? (nowty / joe)

Feel the kerbside pop up? chargers is going to be a massive clusterfu-dge, cars should not be parked on carriageways (roads) this adds more indignant supposed right that need sorting (never) with size & width limitations on immobile vehicles to maximise views for other road users navigating round road-parked obstacles. ..hot topic I know!

Dan runs a cable (occasionally) seems like a metal grid to road with his waterproof cable from his property & a good recessed protected key lock for access might suffice, rather than....

We used your money to install chargers outside your doorstep,... yay
We gave the infrastructure to a profiteering investment company thats going to crucify you per unit of energy compared to your home charger with an extension kept in the car in case you park a few lengths away due to not owning the space directly outside your house, never have never did, but at least its your tariff not a greedy company got you over a barrel!

+1 Mr Gus,

For those reading archival material, latterly.. (TOU ..time of use tariffs)

I don't understand the hype behind V2G. The batteries in cars aren't build for as many cycles as the ones we use for charging houses, so what's the point? I understand that as a backup it's ok, but then doesn't this cost too much to use it only as a backup?

Hype built on unfounded stupidity, probably stemming from the "if everone switches on a kettle when corrie adverts come on" mindset.. etc.
Not having earlier chargers capable of lower draw options, & lack of understanding by public, ministers may well have got us here.
Slow uptake of solar, expensive dual chargers (eg zappi) & no real count of rooftop solar contributions in all this ..which aint mere crumbs if you consider nowtys "secret list" figures.

The idea got so far & reasonable or not the govt want to see it through, ..& something something tax you.
Can you turn a bev car battery into a sound & profitable energy battery cum cash generator? .doubtful.

My understanding was that v2g was pricey to arrange as a consumer for my Nissan leaf. So I sold it and ordered a Tesla Y,....they didn't do V to anything so I skegged around and found the Hyundai Ioniq 5 which does v2h.

Ordered that, cancelled the Y and today I have a huge external battery pack which I can use at my home if need be and a nice car to cut about in all in the same package.

Life has taught me to put faith in nobody, not politicians, not King's, nobody. Can waste a lot of frustrating time waiting for the latest prince's of the universe to get it all in line or realise they're just dicks with a Mic and do what you can with the Tech to hand off your own back.

Well that's my take on it anyway.

Yup!

If getting power back out of an electric car to be used for domestic load (power your home - vehicle to load) and local network support (vehicle to grid) is ever really going to make sense, it's got to be done at the lowest cost. Therefore doing it via DC makes no sense - absolutely ridiculous to install big and costly DC chargers in every home! And also frankly, for the type of V2H loads, 7kW from a Type2 AC socket is more than enough.

For the DNOs, aggregating lots of BEVs on the local network that could all do V2G is a very nice idea for them as they can create virtual power plants to draw small amounts of power and energy (1-2kWh per V2G session) from lots of big EV batteries for short periods of time to help balance the network - without themselves having to make very large capital investments in their own batteries at sub-stations, or increasing the capacity of transformers etc. And there is a certain amount of logic too saying that car traction batteries are very large and so therefore valuable and useful, and cars are sat parked up moving nowhere for 90% of their entire lifespan.
