Again, please tell me otherwise. Please tell me I don't have sweat bullets with looking at 2016 models on Carvana with more than 30,000 miles or more than 40,000 miles or even more than 50,000 miles.
There is one Spark EV that has over 100k miles. The owner posts here.
My '14 at +65k miles still shows mid to upper 70's miles of range on the GOM , now that spring has sprung!
But I still use a little heat and defrost and I always
flog the little beasty in the left lane in rush hour traffic. 70-80 mph, but with some slow bumper to bumper in the evenings, sometimes.
If I drove the slower country way to and from work I'm certain it would be displaying in the 80's again!
I don't know how this is explained. It got better after the SW update when it was in the shop for a long repair/dispute over what is covered by the 8yr/100k mile power train warranty.
I haven't calculated kWh capacity in a while. I'll start logging that again soon.
Well, it's good to know that GOM still displays high range on a high mileage Spark EV, but unfortunately yours and probably the 100k one use A123 batteries, and comparing those to the LG Chem batteries in the newer models is probably like comparing apples to oranges. Things will get even more confusing if GM decides to switch to another supplier further down the line, such as CATL or SKI, since I heard LG Chem is being rather mean to its clients.
Like I said, as I look at the selection on Carvana right now, the average mileage of the 2016 Chevy Spark EVs available is around 30k to 40k, so it would be helpful to know how much the 19 kWh LG Chem battery has decayed by that mileage. That kind of mileage makes sense, because that's about how much you'd rack up from an average length work commute over the course of 3 years, so hopefully someone will have data soon. Fortunately, all of them seem to have fast charging provisions, so they'll be compatible with EVgo, Electrify America, and other DCFC stations. If MrDRMorgan's post is any indication, the battery seems to decay twice as slowly when using DCFC, probably because of what others have said about DCFC helping to balance charge between all of the cells in the traction battery. It seems that DCFC might be the way to go, even if it's more expensive than slow charging at home. Though recently, I've heard it's possible to put a 100 amp 220 volt circuit in your home, so it may be possible to get DCFC at home. Are there any good reliable 22 kW SAE CCS home DCFC chargers that can balance the cells?
