I’m not sure what you’re suggesting here for the charge cycles. Clearly a 5 year old car that dives 10K a year vs one that dives 100K a year is going to be different. Doesn’t matter if it’s gas or electric. If you put more miles on it, you’re putting more use on it.
The battery management, charge state, highs, lows, temperature, all the electronics monitoring the battery and working to give it the longest life possible are vastly different between a car, tablet, phone, or even one of those solar generators. Trying to compare the lifespan from one to the other is like comparing a NASCAR Camaro to one you buy off the lot or a Malibu. They’re all Chevrolets and that’s where the comparison stops.
This is a time and volume question connected with demand. Enough market demand based on prior sales volume and remanufactured or third party battery packs make sense. Small enough numbers and it doesn’t. It’s not like the different packs are really that different at the individual cell level. They’re assembled and packaged differently. Today that the the relative percentage of the entire active vehicle fleet is small enough to not drive this type of product isn’t a surprise. It’s something that will change over time though, at a rate that may not be fast enough for what everyone would like to find replacement parts.
Still though, the Prius Hybrid has been out for 20+ years, and the initial Teslas for 10+. Is there some common scenario where the batteries in these cars are being replaced after 5, 10, 15, 20 years already?
I get that the battery is a big expensive single component and that it’s a relative niche part compared to the size of the US vehicle fleet today. But, is there any history showing that it needs to be replaced at any significant rate? I’m trying to understand the part/expense concern vs the rate of that concern happening. Is it 1%, 5%, 10%, 25%, more of batteries that have to get replaced because of age or mileage in what is otherwise a working (enough) vehicle?
