The below message from Bill D. is interesting and points out the loss stack up
quite clearly. I use a PM100 (Rinehart Motion, now Cascadia Motion) inverter
with an induction motor (Ford ranger EV Siemens surplus). The up side of the
PM100 using the simple state machine mode and the direct

For decades EV hobbyists dismissed regen as not worth the extra effort to
implement. "Just add another battery or two,"
On another discussion list, I asked users in the Colorado Rockies (and
elsewhere) if using the foot-pound to kwh conversion rate provided a
reasonable estimate of kwh consumption and regeneration numbers. It
seemed to. So for a Model Y at 4416 pounds with two adults and
luggage, the vehicle
The cool thing about an efficient EV powertrain is regen can give you a lot
of this back when you go back down the hill!

Well, until you start going uphill then weight becomes significant again.
FWIW, back in the day I noticed that my diesel F-250 was significantly better
at coasting than my other vehicles. Yeah it had crap aerodynamics, but 3 tons
of inertia does make a difference

Well, that’s not how efficiency is measured but I think I know what you mean.
The Wh per mile is mostly a function of weight. Aero starts to weigh in around
55mph. On conversions a good estimate is weight divided by 10. My car weighs
3100 lbs

Mark, I'd say your Tesla is doing pretty darn well for such a portly
vehicle. Over 2 tons! Yikes.
Some carefully designed conversions have managed outstanding efficiency.
James Worden of Solectria was obsessive about it, and Forces (Geo Metro
conversions) routinely got 150-180 Wh/mi when
y is about 3 miles per kWh, measured at the battery, or 333

Hi folks
My heavy 4400lb Tesla Y is more efficient than I thought, close to EPA rating,
