The 2018 LEAF is spec'ed to have V2G, but where are the solutions. I think the new 2018 LEAF is largely dead on arrival compared to the competition. A real V2G solution would be a reason to buy a LEAF.

Nissan would have to find a way to age the battery warranty according to V2G usage so that someone doesn't wear out their battery with very few miles traveled.

Based on this study's findings, V2G is a great way to wreck your EV battery:

Any use of V2G would have to compensate the EV owner, which the utility would gladly do.

While production rates are generally 4-6 cents per kWh, peak power production rates are much much higher. If V2G could prevent a utility from having to fire up an old coal or diesel unit for 2 hours a day that would be a big cost savings.

If you "sold" 40kWh of juice from your battery to the utility for $.06/kWh 250 days/year you would make $600 per year. Doesn't sound awesome, but might make up for the capacity loss.

Worth noting that this study was done in Hawaii, which is pretty tough on the Leaf. Also worth noting that electricity rates are insanely high, so V2G would probably still be economical even if the utility had to buy you a new battery every 5 years.

V2G marches on - just not in North America:

V2G will never spread to regular consumers. It will never pay back. Never*.
And n00bs are so ignorant... it funny to look through eyes of engineer how fools are catched into that :lol:
Almost the same as F00lcell vehicles :) Might work in special scenarios while still being transitional technology.

*applies until 2050.

Since I now have a large enough battery to make it feasible, I am interested in V2G or V2H to handle relatively short power outages at home without starting a generator. I would evaluate the possibility of V2G if my utility were willing to pay high enough rates when drawing power from my car to cover extra battery wear, recharging costs, and provide some profit to me. I doubt that my utility will be interested.

I think that in at least most of the US, V2Home will be more effective and available than V2G. There is a system about to come to market here that has been mentioned in this forum Wall...something or other. Here it is: https://wallbox.com/en_us/choose-your-wallbox#

AC coupling (J1772/Type1 and Mennekes/Type2) does not support V2anything.

Absolutely correct. The car must have a QC port of some kind - currently Chademo.
