The @Hyundai Ioniq 5: first car to do V2G (vehicle to grid) with the onboard charger!
(No special DC chargepoint needed.)
And it's immediately tested here in the Netherlands by @WeDriveSolar and @hyundainl.

Great step because V2G can add a LOT of value.

Quick explanation:

EVs can add a powerful demand to the grid at the moment when the grid is already at peak capacity. (Namely when people come home.)

Shifting charging to a later time on most days (called smart charging) makes that peak go away and electricity cleaner.

But we can go a step further by making the car actually deliver energy BACK to the grid with V2G or vehicle to grid. Now the car can actively LOWER the peak and we can TURN OFF GAS OR COAL while the electric vehicle charges on solar and wind on moments when these are abundant.

The problem so far was two-fold:
1) Battery Degradation
2) Bidirectional chargers

Problem 1) is being addressed with ever better batteries that by now far outlast the car. That is the first prerequisite for V2G.

Problem 2) is now being tackled by the Ioniq 5 that has capabilities on board that make it possible to deliver energy back to the grid (or any other appliance). Truly a battery on wheels. Also the perfect gadget to have on vacation or during a power outage.

If batteries keep improving and if more and more cars add this feature we will get a future where every electric vehicle is actively stabilizing the grid, reducing grid emissions, and improving the adoption and business case of wind and solar.

That means that once solar and wind become e.g. more than 50% of energy produced, your car will not only use almost only solar and wind but also actively stimulate the further adoption of solar and wind!

All in all a revolutionary step. Congrats to my friends at @elaadNL @Stedin @WeDriveSolar @MileSolution and all the other partners.

And just let us know if you want us to use your data and integrate it in our models at NEONresearch.nl ;-)

The idea to use batteries in an EV to provide V2G is old. This is a pilot from 2014.

But so far you needed a chargepoint that contained an extra (costly) "inverter" that turned AC into DC.
This Ioniq 5 uses its build in inverter: cheaper/easier.

I would like to delete the previous tweet but I will man up and just admit I was wrong on almost all counts.
