From ICE cars, a BEV will have much reduced running costs. Basicly it's tires and washer fluid. Brake pads and disc will last much longer thanks to regen braking. The AC motor is made to last forever. The battery is the biggest factor. The 100k miles figure for down to 80% capacity makes it a five years thing for me. But considering the degration curve will flatten (is it?) would it be save to assume that at 200k miles will be at, lets say, 70%? What do you think? What about fluid pumps / hoses? Fans? How long is the PEM supposed to last? Are there any reports on dying PEMs?
