“I’ve seen stories where seven year old Tesla cars are being scrapped because a new battery pack costs more than the residual value of the car.”
Odd? the older Teslas had an eight-year warranty on the battery. But when degraded into beater status, often cost-effective to part them out.
“I wonder if this payback calculation takes battery depreciation into account”
A very good question!
The Nissan Leafs are the same way.
Who’s gonna put a $8000 battery in a car like that?
