Capacity Loss on 2011-2012 LEAFs

Agreed - my hope is that they produce a higher quality, more heat resistant battery pack that also supports bidirectional energy through the CHAdeMO port in an accessible manner.

All LEAFs built since 2015 support bidirectional charging, but in the US the focus of this feature is for commercial fleet usage to help companies mitigate peak usage demand charges. There are no plans to provide consumer facing applications.

More accurately, that phase is still in the focus group stage.

There are no plans in the US to offer a consumer facing offering, period.

Is your garage un-cooled, partially cooled, or air conditioned? If un-cooled and you get breezes, you may want to park it outside, at least at night.

It's a separate, unconditioned garage. What I've determined, using my thermal "gun" is that the garage floor temp remains much cooler than the concrete driveway that is exposed to the sun and tended to keep the battery cooler than the day time ambients (95+oF often!). Sort of a heat sink during the entire summer. The worst case was when forced to park long periods out of the shade in direct sun during the summer - especially on black pavement - battery would get into high 90's.

If you could PM me on this topic - I'd like to discuss in more detail.

But if you bought a magnum power or other bidirectional V2G charger, it would work, right?

Can you send me a link to such a CHAdeMO and/or CCS based bidirectional energy converter with grid protection? I've been looking for several years for a commercial offering (that does not cost $100,000 ).

I've found two offerings that look good:
https://nuvve.com/
- Not available yet, but targeting residential

https://magnumcap.com/en/products/mc-v2g/
The MC-V2G is actually the unit that Nissan is currently showing off, but whitelabeled

I did contact this company and got pricing. Since it's not on their website, I won't publish it, but you could reach out and talk to them. I will say its price may interest you.

I don't know if these units are purely V2G or if they can install with a transfer switch as well to provide backup power. If you could buy a 40 kWh Leaf and use it for backup power for your home in the case of an outage, it's really compelling.

I'm looking at these solutions because it'd be cheaper to buy a 40 kWh Leaf than 4 powerwalls, and if it provided backup power in the case of an outage, I'd have a backup power solution that I could also drive around. Better yet, buy a wrecked 2018 Leaf for $8k with a functioning CHADEMO port and battery, and permanently park it in your Garage. The possibilities are quite intriguing.

Thanks - I am somewhat familiar with the Nuvve work - trying to find more about the AC unit and it's functionality, i.e. does it require a "converter" in the EV itself, since it appears to be a bidirectional charge controller. Also, can it be configured as grid disconnect/transfer - for back up).

The Magnum Cap does look interesting - I'll followup and let you know if learning anything important. I totally agree on "backup" in case of outages. A reasonably priced alternative that is potentially DC coupled with solar..... maybe someday!

My understanding is that the 2015+ Leafs support bidirectional Chademo, although I've seen posts of 2013+ and 2014+. If that's correct, I think a compatible V2G charger shouldn't require any special hardware or converters in the EV itself.

Details from Nuuve are quite light as they're still in startup mode. I don't know if they're only offering time shifting or if they also are providing disconnect/transfer for backups.
