Personally, I'm pretty sure that this is an outlier. Battery health and degradation have been discussed at great length on this forum going back to 2010. Yes, this new case is disconcerting, but unless we see this with much greater frequency, there is no need to get nervous about it. The vast majority of us will be fine, and aside from the occasional module replacement, these batteries should prove to be more robust than we thought possible.klapauzius wrote:In any case, I am still hoping this is an outlier, but it leaves an unpleasant feeling. Adding to range anxiety, we now have capacity anxiety as well...seems like EVs are not for those faint of heart
What I found interesting is that all the known cases of what could be described as premature battery aging were clustered in and around Phoenix, AZ. It would be good to have some organized way of collecting and keeping data from a few hundred owners.
