- foxglacier 3mo agoThat's 25000 miles per year, which is high. So the opposite of false.
- defrost 3mo agoThe comment above is (I would guess) about the eleven years of original battery usage rather than the mileage. The implication being that runs counter to the claim of "calendar age degradation".
- foxglacier 3mo agoDo you mean 11 years is a "long" time? I'd say it doesn't matter how long it was - it ended up better the expected based on the miles, and since it was a high-mileage-per-year car, that supports the claim that degradation is determined (at least more than expected) by calendar years, as cgyv.. claimed. I don't see how it doesn't support his claim.
- defrost 3mo agoIt's all moot speculation in the absence of any firm notation of what cgyvbunji considers "calendar age based degradation" to be.
- cgyvbunji 3mo agoThe battery industry defines calendar age degradation, not a random guy on the Internet like me. It's like saying you can't discuss voltage without me defining what voltage is.
- imtringued 3mo agoSo according to you, the more you degrade the battery, the longer it lasts? Usually you would think that 25000 miles per year over 11 years would degrade the battery faster than the car just sitting around for 11 years.
- foxglacier 3mo agoAccording to cygv... the more intensely you use the battery, the more miles you get out of it, so kind of yea, the faster you use it, the "longer" it lasts in miles. And this example supports that idea because it was used more intensely than usual and lasted more miles than usual.
- cgyvbunji 3mo agoYes, exactly, as long as you don't fast charge. The ideal scenario for TCO measured as dollars per mile driven should be driving every day until you are down to some threshold, slow charging overnight, and repeating that each day until it's a brick. Should end up with something like 200-300k miles that way.
- small_model 3mo agoOP said 'They still die by calendar age based degradation', they don't was my point. They degrade based on charge cycles.
- InsideOutSanta 3mo agoMy EV is also over ten years old and has no noticeable battery degradation. I'm sure there is some degradation that could be measured, but in daily driving, I have the same range I did the day I bought the car.
