Re: Stoaty's Guide to Energy Efficient Driving of the Leaf

There are several different numbers that people use. 30% would be at the high end for the overall efficiency increase but too low just for the efficiency of turning kinetic energy into chemical energy. Of course it can't be greater than 90%. A guess of 70% at the highest end wouldn't be bad (80% drivetrain efficiency X 90% charging efficiency).Stoaty wrote:I am pretty sure I saw that 30% number on MNL. When I looked up Prius regen efficiency, best guesses were 30-50%. If it is better than that, I would like to see a reference. Don't know the real answer, but doubt the 80%. That would be phenomenal.
This is one way efficiency. Roundtrip efficiency would be more like 55% assuming your drivetrain was 80% efficient (80% out X 70% back).
The Prius battery is considerably smaller which will limit the amount of regen it can handle.
