This is a fantastic article on the real world pros and shortcomings of V2G.

"What’s more, when we looked at data from other ACT government vehicles parked in these properties, we found 23 were charging throughout the event. Again this directly obstructs power system recovery. There would have been absolutely no inconvenience or cost for the vehicles to delay charging for an hour or two. "

There are some very "of course we should have thought of that!" moments that highlight not only the potential, but also the work ahead to make it a positive reality. Much more good than bad here.

Go Australia! Make those legacy American/Japanese automakers blush.

WTF are you even talking about?

The EVs used in this trial were made by Nissan...a legacy Japanese automaker. This type of tech is also built into at least Tesla and Ford vehicles.

For clarity, Ford Lightning and Tesla Cybertruck are the only V2G (Vehicle to Grid) compatible products in those companies. I would really really like it to be wider in both company's product offerings.

I'm sure it will become wider spread as we go forward. V2G tech is pretty new so it stands to reason that it would only be found in the newest models.

It isn't though. As proved by the article, the cars in question used were Nissan Leaf cars, which came out in as early as 2009. V2G was built into the Chademo connector and implemented on day 1 by Nissan.

Both CCS and NACS( J3400) include V2G in the spec, but only two cars total (Lightning and Cybertruck) that I'm aware of have implemented it. EV manufacturers are likely worried about battery life and warranty. EVs with V2G might have their warranty terms evolve from "number of miles driven" to "X number of cycles of battery or Y number of miles, whichever comes first".

Nissan ran it's first V2B (building) test in 2011. They did not have V2G in 2009, even if it was built into Chademo. In order to get from V2B to V2G Nissan entered into a partnership with Fermata some years after that V2B test. In fact if you go looking the Nissan Leaf didn't get it's first US approved V2G charger until September of 2022, which is less than two years ago.

As for Chademo it wasn't officially developed until 2010 and even if they snuck a pre-production version into the 2009 Leaf the 1st Gen Chademo only supported 62kw charging, which isn't nearly enough for V2G to be practical.

So saying that this isn't new technology and that the 2009 Leaf could have done it are both inaccurate statements. Nissan didn't have the tech, the connector didn't have the tech, and Nissan approved UL Listed Bi-Directional chargers that supported V2G didn't exist for another 12 years or so...and I'm about to show you why that last one took so long.

Both CCS and NACS( J3400) include V2G in the spec

It's not in the CCS spec until 2025 and J3400 literally just added it in February, barely 5 months ago!

...but only two cars total (Lightning and Cybertruck) that I’m aware of have implemented it.

Yes, because the damn spec for V2G is so new that only the two or three newest designs were able to include it.

According to every reputable industry source I can find V2G is NEW and so it stands to reason that only the newest vehicles in the American Market have support for it right now. I'm sure as time goes on that it will be added to additional vehicles.

Edit: GM is adding V2H to it's 2024 EV line-up, it's not V2G but it's a big step in the correct direction.

I’m talking about these companies being hesitant to necessary progress in general
