Comment on What *Really* happens to used Electric Car Batteries? - (you might be surprised)

I hope this comes to the UK and other countries, help drive down the cost of the car batteries as I’m dreading replacing my electric car battery

If you’re talking about replacing the battery in the car because its worn out and no longer usable as a car battery, you’ve likely got 15 or 25 years before you’d need to do that.
Modern liquid cooled EV batteries last a really long time and don’t usually straight up fail, but degrade slowly over time. The oldest batteries like this are usually from circa 2012 or so Tesla cars. I wouldn’t count Nissan Leaf because they were not liquid cooled and we know overheating is the quickest way to degrade a battery.
After 200,000 miles of usage, the battery only degraded 12%. So if you have a battery at new that could go 315 miles on a full charge, after 200,000 miles of usage it can now only go 277 miles on a full charge. Would you replace the battery for only that?

If your commute is 278 miles yeah. /s

This is something I’ve had a really hard time drilling into peoples’ heads. Based on current data, the average EV battery built today wont fail in 10-15 years; they’ll just degrade 10-15%. And yeah, in that time period, at current gas/electricity rates, I’ll have saved $30K in gas alone (I saved 2K last year * 15 years = $30K) and it stands to reason that gas prices will continue to climb. Electricity as well but once it hits 20 cents per kWh for me, I’m getting solar.
