afe66: I found the data plot of the battery SOH vrs time very interesting and reassuring.
Looks like probably 1000s of data points showing there isn't an issue with lots of batteries failing.
Any mechanical thing will have a freak failure.
Reminds me of a friends petrol Hyundai bought new then had a complete engine failure and he ended up talking to CEO of hyundai nz who fixed it after local dealer wasnt interested..
All EV batteries degrade a bit every year (some more than others depending on fast charging etc etc) but I don't think the same can be said for petrol engines. You can buy, say, a 2007 petrol car without worrying about whether the engine is going to have to be imminently replaced! But, even a 5-year old EV might run into battery problems that an unsuspecting buyer wasn't expecting.
Nevertheless, I like EVs and will buy one as my next vehicle, but am well aware of all the pitfalls of EV ownership. For example, this article talks about "an increasing number of individual cell failures in 30kWh Leaf battery packs":
From the above:
We suspect that in many other countries, Nissan’s support there is the main reason why we haven’t seen more reports of these failures worldwide. However, in our home country of New Zealand the opposite is true. All 30kWh Leafs arrived in NZ as used imports which Nissan NZ have been unable or unwilling to offer battery support for.
