Honestly it seems like a no-brainer to me to put a solar panel on the roof of electric cars to increase their action radius, so I figured there’s probably one or more good reasons why they don’t.
Also, I acknowledge that a quick google could answer the question, but with the current state of google I don’t want to read AI bullshit. I want an actual answer, and I bet there will be some engineers eager to explain the issues.
IIRC some car batteries can be used that way, but it wears out the battery.
For LFP batteries it’s irrelevant. They have a 3000 cycles to 80% cap, some of the new ones have 6000. That’s 10 or 20 years assuming full discharges an recharges everyday.
Or in terms of lifespan, assuming a realistic 400km range (250 miles), it’s between 1.2M and 2.4M km before the range reduces to 80% (750k and 1.5M miles). The car will be completely Theseus-ed at the point.
