A comprehensive analysis of over 10,000 electric vehicles reveals that battery degradation is a slow process, with most power packs capable of lasting 20 years and retaining a majority of their original range.
Am I reading their data wrong? Looking at the bottom graph, the battery loses 20% of it’s life in 4 years if I fast charge once a month & live somewhere hot (yes to both for me). That’s 5% a year, but the article says 1.8%. That’s a pretty big difference once we account for real world conditions.
Not quite a full 20%, but yeah, in your situation, that’s a big longevity problem. This data is obviously better for people not living in very hot climates.
It looks like the first graph (which the 1.8% average is pulled from) is keeping climate constant (and probably temperate.)
