On an electric vehicle, how many battery replacements would be needed to reach 200,000 miles?
Ours is 29 months old and has 57K miles on it with no reduction in range. I'm sure that day is coming. I told my wife that when the range is reduced enough to make the EV not practical to use on long trips, we'll use the gas pickup. I'll replace the battery only if it's cheap by comparison to buying gasoline on long trips.
Our main use for the EV is local driving. We drive 15K miles per year on home-charged miles, not including the fast charging done on trips. So even after the battery's range is reduced, the EV will still do the main thing we want from it.
