TL;DR Most EV batteries will last longer than the cars they’re in.

@bob_zim I think I do recall that, actually, but to be fair, anyone who ever tried to keep a ghetto blaster going on NiMH D-cells knows that was doomed from the start.
@jpaskaruk @bob_zim @jwildeboer my boomnox had 8 and drained them pretty fast. Lol

@dalias many newer cars manufactured in the past 20+ years will not make it to 25 years due to electronics failing (capacitors and mosfets are typical candidates), regardless of being powered by ICE or EV.
@jwildeboer See: "atrociously bad quality of cars". This wouldn't be a problem if swapping out the electronics were trivial, but when you have an intentionally locked-down shit Android device on wheels rather than a proper car...

TL;DR Most EV batteries will last longer than the cars they’re in. Battery degradation is at better (meaning: lower) rates than expected. Slow charging is better. Drive EV and don’t worry about your battery.
„Our 2025 analysis of over 22,700 electric vehicles, covering 21 different vehicle models, confirms that overall, modern EV batteries are robust and built to last beyond a typical vehicle’s service life.“
@jwildeboer What about cold days? We recently had about 3 weeks around -40, usually get about 2 weeks a year below -30 C and months of -20 C. In this climate, must people don't have a garage, and those who do generally don't heat them. Any insight?

@jwildeboer yes. Data doesn't go that far.
@renard @jwildeboer battery degradation slows down over the lifetime. Although this probably depends on the chemistry.
BEVs typically have lower maintenance, so I don't see why 20yr can't be matched. If (e.g.) 70% State-of-Health is acceptable 20-years in, i guess it's still a viable car to drive.
However, I'm not sure why "20 years" is a metric to hold up against. Is that primarily a financial consideration? Worded differently: Would you buy younger for the same price?

@dynom 20 years is a weirdly special metric, considering that EVs have not been generally available 20 years ago and the progress has been impressive in the past 10 years. But hey, petrolheads gonna petrol, I guess

@jwildeboer @dalias I wonder how much it varies between companies - like if traditional manufacturers are still at least trying to build to last (within the limits of designs these days), while more techbro-derived manufacturers lean harder into planned obsolescence to try to impose short upgrade cycles..

@newstik @jwildeboer It must not be too large a problem. Nearly all new vehicles sold in Norway are EVs.
-
@jwildeboer that just means one has to buy a battery that’s 5/4 as large as one really needs
@jwildeboer SoC limit usually has to be set by the user, BMS does not do this automatically. However @mirabilos your point is invalid. The typical daily range that is driven is 20km or less. So you don't need to charge up to 100% all the time. Just as almost nobody always leaves a petrol car with 100% fuel level in the garage every day. And if you are going on a long trip, there is no harm to charge up to 100%. Just don't do it every time and leave it in that state and you'll be fine.

@JYeo18 @jwildeboer Yes because they are massively subsidized there compared to conventional vehicles. In that environment, I'd happily buy a car that is guaranteed to go up in flames after a decade. That doesn't translate to other parts of the North.

@jwildeboer I bet that study jinxed it for everybody.

@jwildeboer @acidicX yes but the use case I’m eyeing (due to circumstances) is daily nothing, and very occasionally either 10 km or 80 km

@jwildeboer @acidicX and Inhad been hoping to get the option of a very small vehicle for that

This is truly very interesting! -

@mirabilos @jwildeboer well even the most basic EV currently on sale - Dacia Spring - will handle 80km at 80% SoC without any issues

@jwildeboer @acidicX that’s the bare travel distance, need to figure out how to load them on both sides as well… plus margin, ofc. I was just saying that I’d need to have much more margin than planned, then.
-
This also means that buying a used EV is perfectly fine. If the used car is „younger“ than 5-7 years, the battery will be fine for years to come.
„How long do EV batteries last?
The average lifespan of EV batteries will be around 13 years or more based on observed degradation rates.“
@jwildeboer
5-7 years is new around here. Mine was 11 when I bought it, will be 35 this year.When possible I avoid things with lithium batteries, because the battery is usually the first thing that dies.

@jwildeboer @acidicX it’ll need more planning than just the thing stands there and can be used and occasionally the bother of having to tank petroleum is needed, which was already bothersome
at least it’ll stink less.
