Even a low level of participation from drivers could make a big difference, the researchers said.

I think this part is where the importance of the findings resides, it should be easy to understand the benefits of having countless batteries connected to the grid and how they would help stabilizing it, but that this effect is important and can be observed with less than half of the cars participating in the scheme talks about something that is much more feasible than hoping for everybody to be included. Maybe some small incentive could be enough to convince enough owners to participate.

In a world where most households have multiple vehicles, this makes good sense. Increase concessions on EV purchases to get a greater percentage of EV ownership and do it sooner. For homes with adult children still living at home, they could have three or four vehicles, any of which could be used if they are all EV and having multiple vehicles hooked back to the grid can be a bigger help to the grid and allow that family to perhaps earn some money back during power shortages.

Anything that helps limit global temperatures and gets us off fossil fuels is a good thing. If it allows homes with good solar generation to make some money back then it is good in more ways than one.

Wifi charging is coming.

Tesla is experimenting with the Virtual Power Plant (VPP). It seems successful already just using Power Walls. I’m hoping they add V2G capability soon!

In a world where most households have multiple vehicles, this makes good sense.

the best part is that even in households with one single vehicle this can still be useful because most cars are not in constant movement, so there are times where it is just there parked for hours, as long as it is not required for the charge to be importantly depleted this can still mean that they can support the grid during those hours and still fulfill their purpose as a vehicle without problem.

Not new not practical.

It was studied previously and rejected as impractical, one study said it was like borrowing from one person to pay off another and needing to borrow more to pay back the first person.

Why because of loss, you lose a certain amount in the charging and conversion process AC to DC back to AC.

A car better idea is to give up on solar as it is this myth of "oh free energy" well only on nice days only if people are using it when available only if you can store it in toxic batteries.

Move to more wind new Turbines start producing a very low speed, add piston or gravity generators ( during peak production pistons are compressed or weights lifted in low wind these are released causing the turbine to produce more power if needed.

I know the sun worshippers will down vote but facts are facts.

Solar is possible in very specific locations but think hard where in Europe is it practical, maybe southern Spain,

Give an idea the UK gets on average 1400 hours a year of sun that is 4 hours a day

France does better with around 2000 hour

Germany is the same number 200 hours but that is only 169 days of full sunshine the rest are cloudy

Japan get 1800 hours on average in the country

With some prefectures as low as 1500 and other as high as 2100 hour this is between 140 days of sun to 220 days the average 170 days.

Compare that to wind in Japan at lowest times still averages 5 to 10 km/h and is blowing nearly 365 days a year at least over 5km/h

Place turbines near the ocean or on mountains we can generate far more per square meter than any solar panel.

I would expect that during power shortages, anyone with a full charge on the EV that doesn't need it to drive would utilize that power for their house, not the grid. I suppose it could still help by reducing overall power demand, but wouldn't think it would be viable as a grid storage solution.

Another interesting solution is DC housing. No conversion necessary.

How is this a new study? The idea of grid sharing was part of going electric. After work, vehicles would plug into the grid offsetting home demand then when everyone is sleeping their cars are recharged. Not rocket science and not even new...

DC is not good for domestic use for appliances. More dangerous than AC. Worked in a factory with its own DC generators. Walk too close and it would ark and strike you in the leg. Very painful.

Give it up. The concepts are wrong right from the start. And you also won’t beat the main and basic rules of physics, chemistry, science in general.
