Mono Posted October 2, 2017 Share Posted October 2, 2017 This is the consumption distribution [Wh/km] I have recorded for my V8 over the last 2900km (rider weight ~80kg, all are round-trips). How to read this: I have been riding 150km overall consuming below 12Wh/km, 500km consuming below 14Wh/km, 1400km consuming below 16Wh/km etc. When I go from A to B on flat terrain at 20km/h I am at the low end of the spectrum, ~11Wh. Usually I am above that, because I have some moderate hills to climb (30-100m difference in altitude per trip). When I am fooling around practicing quick turns, braking, slalom etc I am at the high end of the spectrum, ~19Wh. I also computed the range distribution from these data, assuming I can use 400Wh of the nominal 460/480Wh battery. For example, 80% of the time/trips I am riding with a range of at least 22km, 50% of the time/trips with a range of at least 25km, 10% of the time/trips I could ride 30km, etc...

Noillek Posted October 3, 2017 Share Posted October 3, 2017 This is great visualization of how efficient the wheel is... i'm curious to know how other wheels would perform under same conditions, and see if theirs indeed a way to make a wheel cover more distance using the same battery/engine/tire/tire pressure/rider weight under controlled environment... this would explain us if some brands make any fine tuning on how the energy is consumed. So far we as consumers only worry about wheel size/wheel weight/size of battery pack/engine power... although we see for instance a V8 with a super small battery covering long distances "apparently" easier than other wheels with same or more batteries. Need to track my Wh/km consumption... Link to comment Share on other sites More sharing options...
Chriull Posted October 3, 2017 Share Posted October 3, 2017 @Mono: how did you get the Wh/km? Link to comment Share on other sites More sharing options...

I measured distance with the V8 app and Wh with the charge doctor using invariably 81.5V as turn off trigger. Most of the time the travel distance between two measurement points was a round trip of between 10 and 20km. Link to comment Share on other sites More sharing options...
Mono Posted August 17, 2018 Author Share Posted August 17, 2018 I am ending my energy consumption recording for the V8 after 6000km. Below are the plots of the final data (see above for how to read the graphs). Typical consumptions (including charge losses on the battery side) are between 11Wh/km and 20Wh/km. The median and the average consumption over 6000km was 16Wh/km. I usually have some significant uphill or idling parts in my trips. Link to comment Share on other sites More sharing options...
