It'll take a while, but eventually the used market will fill up with EV's, making them affordable for regular people.
To be honest I feel very uncomfortable buying an EV on the used market. Mainly because you don't know how the battery was charged/used.
The recommendation is to keep the battery between 10 and 90 or 20 and 80 for battery longevity. But a lot of cars ending up on the second hand market are leasecars. And they don't care about the battery that much as they'll return it anyway in 4 years.
If you buy a 2nd hand car that is 4 years old and your battery is ducked after 3, you might as well buy a new one given the cost. Something I feel is less of a risk when buying 2nd hand ICE cars ( though the clutch on those cars is usually ducked because people need to start-stop like a racedriver because reasons ).
you need to look into some of the ev’s made in the last few years, i doubt even the worst offender could get a battery to sub 90% battery life in 4 years
that’s 7 year old battery, most have a warranty of 160,000km / 8 years these days
i think the very first gen ev’s / nissan leafs with crappy passive cooling and smart phone batteries have planted the idea that batteries are a very delicate thing that needs constant maintenance, most 5 year old ev’s will have 95%+ battery health with another 10 years of life left
While I do feel the same way, it’s hard to not draw a comparison to the way you have no idea whether a used ICE car was maintained either. Many ppl will go thousands of miles over the recommended oil life for example, or they won’t top off coolant, or they won’t service the transmission. Many of those will result in failure with expenses rising to that of a new car too. It’s just a reality of used cars.
I do think that in EVs though instead of many cheaper parts that can culminate into a huge cost for the buyer it’s much more scary to have one part that if it goes you’re just screwed.
Most teslas have the 80% battery limit built in so you have to override it each time to get it over.
I don’t know if other brands have it too but I imagine if it’s made difficult to overcharge the battery then they’ll last longer on the second hand market.
Hyundai has a setting to choose when to stop charging. I typically charge to 80% except before a road trip.
That is true for DCFC but not L2.
