I’ve read elsewhere that the end position cell(s) are cooled least and so more subject to this failure, but really don’t currently know enough to more constructively comment on that.
120k miles, as in the video for the Taxi, sounds a lot but these days I’d expect that out of any car. Forty years ago my family parted with a 2CV , it was running well and had 150k miles on the clock.
I keep turning up decade old numbers, but the average mileage at scrappage in the uk is reported as between 106k and 125k - that marries up with the ~13 years typical age that is more current with ~8km/year typical usage.
I'd also wager that your family spent some not inconsiderable time and effort maintaining the 2CV in good running order.
Thanks for posting that video of a Leaf's battery repair, it helps de-mystify the whole subject. As for you saying it's a fairly easy job, that applies to anything if you've the correct tools, working environment, correct frame of mind and knowledge. Does anyone know if there any BEVs which have a particularly awkward to access/remove battery?
I know a lot of people are perfectly happy to take a vehicle manfacturer's word for it that their latest model is genuinely new and improved but plenty more prefer to have a more informed choice a few years down the line, when the products themselves have done the talking.
When conventional cars were still improving enough to have children waiting for new models to be released, the difference between good (as in 2cv described by CG) and less so was often very well defined, even though marketing and general ignorance/bias tended to gloss over or hide the facts. We're only a few years in to the mass production of the BEV so I wouldn't expect quite the levels of long term reliability which the ICEv has reached, the thermally-crushed battery cells from a UK Nissan make me wonder how the cars perform in a hot climate.
Can anyone describe the what I presume is air cooling for that Leaf's battery? Is it fan driven, for example? I assume there are or will be some straighforwards modifications which battery specialists will make to prevent such overheating when fast charging, or when driving in a way which makes the battery work hard.
