Electric Cars Could Last Much Longer Than You Think - Rather than having a shorter lifespan than internal combustion engines, EV batteries are lasting way longer than expected
Rather than having a shorter lifespan than internal combustion engines, EV batteries are lasting way longer than expected, surprising even the automakers themselves.
You're viewing a single thread.
From the aricle: "If this 1.8 percent annual degradation continued in a linear fashion, after 10 years an EV would still have 82 percent of its battery capacity, much more than the 70 percent most batteries are warrantied for after eight years."
The battery degradation isn't linear. If the auto makers would themselves believe this, they'd give longer warranties, to encourage sales.
A 1.8%pa degradation over 10 years would be, 83.39%.
Linearising it to make it "more intuitive" I guess.
But 2%pa degradation gets you very close to the 18% over 10 years figure. 1.9649% to be more precise.
Over 20 years you are down to ~67% and ~55% at 30 years.
And upcoming EPA regs will require the 80%, 10 year claim. I think that starts for MY28? Not 100% confident on the timing
