(29,798 posts)That's fine. You also say I need to come up with some numbers - no I don't. really don't care if you want to participate in V2G markets or not. You've clearly made up your mind to reject the idea, and in spite of me giving you a point of entry into the research (Kempton) you show no inclination to educate yourself.
Yes, generally speaking, indications in the research are that the batteries are going to outlive the car as a propulsion unit - even with V2g. They will then probably have further utility as either replacement batteries in older cars or as stationary storage for energy, such as solar in homes or in large banks by corporations or utilities. Again, I really don't care if you accept that or not.
And frankly, your extremely impressive credentials notwithstanding, I'll take the information I've gleaned from talking directly to the involved researchers and large body of both published and unpublished literature available on the topic. For example, the norm for the for EV battery technology is, at present, 10,000 charge/discharge cycles. And developers are going beyond that. That is what, about 27 years worth of daily charging? And no, I'm not going to google "EV 10000 cycles" for you.
One final point and then I'll leave you to wallow in your contrariness - the idea that the battery must necessarily lose capacity over time is also one that is quickly becoming obsolete.
