Everybody talks about "replacing the battery" but I hardly see that as an issue with EVs. The battery degredation curve on the Leaf projects roughly 75% capactiy after 5 years, and between 60-70% capacity at 10 years. The first few years see the greatest drain on the battery's capacity, but after that the speed of degredation plateus to a lower (but steady) rate.
This isn't stellar for the first generation of EVs: an EPA-rated 82-mile range Leaf at 10 years old will only be getting around 55 miles on a full charge. But for cars like the new Chevy Bolt, it's 238-mile range will still be over 150 miles at 10 years old. And at 20 years old, with only about 30% of it's original capacity, it will still have over 70 miles of range (about what my 4-year old Leaf is doing).
But what if I do decide to replace the battery? We throw around numbers like "$5,500 battery pack", but the only people who have actually had to replace the batteries in their Leaf were done under warrenty due to bad batteries. We don't know if Nissan will even offer replacement batteries by the time the first 2011 Leafs are 10 years old. And if they do, would Nissan be selling 10-year-old batteries using a practically ancient formula, or would they be replacing the batteries with the same modern technology that they have logistical access to (i.e. whatever the modern battery formula is)?
It makes more sense that they would offer the latest battery technology to replace the old battery, and this is exactly what Nissan has said they would do. With continuous market-driven research into EV battery technology, I wouldn't be surprised if a replacement battery either a) is cheaper in the future for an 82-mile range replacement, or b) I pay $5,500 and recieve a 200-mile range battery. I would be happy with either outcome.
In short, worrying over replacing the battery is least on my mind.
