Second hand EVs - mileage or age?
Discussion
Is mileage or age more important for 2nd hand EVs?
We have been conditioned to balance mileage v age when buying 2nd hand ICE cars (High miles, newer car v the low miles, older car). But with EVs should battery age be more important than mileage? Higher mileage will still mean components like suspension will wear more, but the biggie is the battery.

Focus on battery health. We have been conditioned to balance mileage v age when buying 2nd hand ICE cars (High miles, newer car v the low miles, older car).

In order of preference for me:
How often has it been DC (public) charged vs AC (home) charged.
Drivetrain warranty remaining
Mileage
e.g. i'd happily buy a 5 yr old car with 100k miles and only a little bit of drivetrain warranty left if it's been privately owned and almost exclusively charged at home.
But a 60k 3 yr old car that's been supercharged every day and used as a pool car would have be running for the hills.
All depending on how long you intend to keep it for of course...

Most EVs won't have any drivetrain warranty at 100k miles.e.g. i'd happily buy a 5 yr old car with 100k miles and only a little bit of drivetrain warranty left if it's been privately owned and almost exclusively charged at home.
But yes, you might be right about others.

Old Evs = old tech?
Given the rate of change, I wouldn't want an old one (small batteries, low rate of charge).
They are evolving just like ICEs have done. Battery technology too. Given the rate of change, I wouldn't want an old one (small batteries, low rate of charge).
What do you mean by small batteries? If a persons normal usage is city driving then a large battery is of little advantage.

Out of interest, how would you intend to confirm the above?How often has it been DC (public) charged vs AC (home) charged.

Teslas do have a way to show you how many supercharges they've had, but i can't remember how to do it.

Is there any software available that allows the interrogation of the battery status?
It will depend on the manufacturer. I know there's an app called "Leaf Spy" which lets you query the health of a Leaf battery via the OBD port. I'm sure it's also possible for other brands, the question is just whether anyone has written an app to do it yet. Even if there's no android app available, I'm sure if you took the car along to a main dealer they'd check it for you (probably for an eye-watering fee!).I suspect it will ultimately become the norm to provide some sort of certificate of battery health provided by the manufacturer when selling a second-hand EV of any significant value.

Warranty regarding remaining is most important.
Nope. "But the key to selling a used EV is – and I repeat myself – the battery health status, measured as SoH. CARA proudly offers this new industry standard under an EU-recognised certification scheme. "
"“I believe that EVs without a clearly stated battery health status will be more difficult to remarket, and this as soon as the coming year. With a standardized battery health check, used car sellers and buyers are safe when trading a used EV.”
“For its scheme, CARA focused expressly on using the SoH from the battery management system itself because this is reproducible by any dealership performing a detailed battery analysis. Further independent evaluations will be needed in specific situations, including used EVs that were in a crash, that have damaged batteries, that have an extraordinary value, or where the basic test of the battery management system has shown an atypically low SoH.”

Also the battery warranty seems to cover a failure, but there is acceptable degradation,
Eg Ford:-
“ 8 years
Your electric vehicle's battery warranty protects your components if repairs, replacements or adjustments are needed while you are covered. Your battery is covered for 8 years or 100,000 miles, whichever comes first, retaining a minimum of 70% of its original capacity over that period”
Would be useful to get a reading on day 1, for comparison purposes!
Unless there is a day 1 spec to work with.

You can see this on your mobile phone, and so presumably the data is stored somewhere within the EV software
Have a look at https://get-moba.com/ They are providing certificates on EV battery health to consumers.You can see this on your mobile phone, and so presumably the data is stored somewhere within the EV software

Surely you can take their quoted WLTP range as the benchmark? If they inflate those figures then surely that's their issue? Eg Ford:-
