My implication was not about your approximation, but that so much effort in this thread has attempted to reduce energy lossesvoltamps wrote: ↑Thu May 13, 2021 11:02 amMy approximations don't quite cut it, that's true. That part is laughable. There is nothing like simply trying it on the road like what knightmb & estomax are doing.
The engineering paper that showed about a 1% loss from using thicker oil kind of nails the issue, done in a real transmission. The challenge for physics modelers is to include & know about enough things to simulate it right.
.......knightmb had a good point about there being some (small??) cascading savings effect, when your battery has to provide less watts flowing out to overcome all the losses in the Road Load. Anything saved is less you have to cool with pumps and fans.
in the transfer case by changing oils. Your analysis was more than adequate. Most with basic engineering backgrounds would
intuitively know little would be gained.
