Title: Distance comparison spreadsheet (non-aero)
Post by: togo on February 11, 2020, 04:55:15 AM
Comparing road-trip capabilities of the rapid-charging electric motorcycles: Energica, LiveWire,
Zero SR/f Premium 6kW and 12kW, and Zero SR/DSR with aftermarket, as well as BMW's and
Johammer's offerings.

At high speed, of course, a full Vetter Challenge aero shell will of course drop energy use in about half.
Craig Vetter's teardrop shell is designed for 90 MPH windspeed (60 MPH with a 30 MPH headwind).

Great work putting all this together! Only question I have; is the Wh/mi consumption really pretty much the same across all makes/models? I assume some models would be better/worse at slow/high speeds due their gearing and aero.

Edit: It is nice to see that the Energicas truly do save time by driving at higher highway speeds thanks to charging at 26 kW. Only issue is that I'd probably spend more money on energy than fuel at the current Electrify America rates.

I'd love to see the Zero FX/FXS added to this!

Brandon said he has data for Energicas and Diego is going to collect data for LiveWire so hopefully those columns will become more accurate.  I used what I had as a starting point, Zero experience, add I suspect the igbt-based higher voltage controllers are less efficient than the mosfet-based sevcons, but that might be offset by transmission kisses, thermal issues, we will see. I'd be surprised if it differed by more than a percent or two.

What's the data?  Energy use at various 40, 60, 70, 80 mph, and I can look up nominal battery capacity on zero's site.
