"Tesla Tech Talk (06/13) - Speaker's main points:
1) battery degrades everyday
2) battery degradation is non-linear over time; meaning it starts very very slow, but after 4-5 years, it gets faster
3) after the first 5 years, degradation may be as low as 5%. But by the 8th year, they expect about 30% degradation."
Batteries will without any doubt seriously affect second hand markets for EVs. Especially when considering cold climates and the fact that the range can be quite limiting even when the battery is brand new.
in 2013, there was no data to tell what happens after 8 years of typical use, first Model S was just a year old by then and even more intensely used ones didn't have that much use - 8 years of normal use equivalent. Now there are many of those that were driven beyond median lifetime of a vehicle.
I have no idea what to make of the claim that no further degradation is expected. It's not like batteries are a new not understood technology, batteries don't behave like that.
Is that an ad?
It is expected for the capacity to drop off significantly with age. The main weapon tesla has used against this is good cooling and sensible charging patterns, but that is just stalling the inevitable.
