As I pointed out before, you seem to be confusing the definition of "efficiency" in the paper (percentage of stored energy that makes it to the wheels) and "efficiency" meaning the amount of energy required to travel a given distance. |
1) Not to sound like Bill Clinton, but we need to clarify exactly what you mean 'heavier' EV.
2) I'm only talking about the 2015 Volvo V40, 'small' SUV, at a different weight.
3) Not the Volvo S80, or XC90, both of which have different CdAs as well as higher curb weight.
4) None of the tables presented in the thesis reflects the V40 at a different curb weight.
5) Since last Monday, I located enough data from my archive to scientifically prove that a 'heavier' V40 would be 'totally' more efficient for all considerations. It all hinges upon the ' strange behavior... connected to the regenerative braking which is dependent on available wheel power and mass.'
6) It's a page full of data, including Volvo's own solution for the 2021 model year XC40 P8 AWD Recharge ( R-Design).
7) It's quite damning to your hypothesis.
