How does efficiency change with load and rpm for the generator?

How about the controller?

What is the overall efficiency in terms of vehicle speed and load?

And is energy moving "through" the batteries? What conditions affect the charging/discharging efficiency? (not counting regen)


Like we don't consider ICE engines to be really 35% efficient because of operating conditions, we should not make the same mistake with electrical drivetrains, no?
