Popular Post Halig Posted January 19, 2021 Popular Post Share Posted January 19, 2021 (edited) I have done an autonomy test on my V11. Since I don't have TV, I need to entertain myself with something . Results: ✅ 97,18 km (about 92 km indicated by GPS)🌀Time: 4:02 h (continuous, without stops)🌀Tilt-back set at 25 km / h🌀From 100% to 10% battery 25 km/h exactly. Then, alt 10% in tilt-back battery warning -> "Go Home" activation —> drain the battery until 2% —> final tilt-back and final test) and slightly less speed to prevent cutoff🌀Temperature outdoor: 8º start, 4º final🌀Average consumtion: 14,6 Wh/km🌀Average riding: 24,7 km/h🌀Circuit test: 2 km round trip. Totally flat (following river). Zero wind (both directions)🌀My weight: 75 kg Since January 11, my EUC World app does not upload routes 🤔🤷♂️, so I only have the CSV (attached in this post in case someone gets any other use ). I think the autonomy can be improved a lot, but I would not know how much 🤔 - decreasing aerodynamic resistance (I was wearing a lot of clothes due to the cold) - going slower, logically - increasing tire pressures (I take it at 2.1 bar) - with more ambient temperature, so that the batteries work better (main board indicated 12ºC at the end)..I think the optimal temperature for batteries is 25-30º? What I really wanted to do with the test (in addition to being curious about autonomy in those "lab" conditions), was to get this graph about the % battery indicator reliability, and I am very happy. I see that the V11 is very reliable in terms of the % battery it indicates. At the beginning it goes down too fast to 90%, but then it is a very reliable line. Logically in more real conditions of climbs, wind, accelerations, etc. It will not be a perfect line, but it has little variability (unlike the V10F that the other wheel I know of). The slowest descent at the end is because, after activating "Go home", I went more slowly, as I mentioned, to prevent a possible cutoff (which I think would not happen, but ..) 20210118 92 km llanos avda. zadorra.csv Edited January 20, 2021 by Halig 15 Quote Link to comment Share on other sites More sharing options...
Spiken Posted January 19, 2021 Share Posted January 19, 2021 (edited) Thanks for your detailed feedback ! Very interesting, 14,6 wh/km for 24 km/h in averrage in winter, this is good (close too my z10 at same speed and nearly same weight).

Rich Sam Posted January 20, 2021 Share Posted January 20, 2021 excellent data there! I wonder what effect a tiltback has on the battery. Did you get many tiltbacks during the ride? It's a shame there is not a cruise control we can set with optimal accelleration \ deccelation values to be battery friendly. Quote Link to comment Share on other sites More sharing options...
Halig Posted January 21, 2021 Author Share Posted January 21, 2021 I had continuous tiltback because I set the speed at 25km / h. They weren't annoying, but it beeped every little bit, of course. I don't know if you mean that Quote Link to comment Share on other sites More sharing options...
Zopper Posted January 21, 2021 Share Posted January 21, 2021 @Rich Sam Tiltback has no effect on the battery. The amount of power needed for it is completely negligible. To the wheel, it doesn't matter whether the angle of pedals is 0 or 10 degrees. And the slower the acceleration, the more battery friendly it is. There is no need for a special profile for that. We need the wheel to catch us on a bump, no matter how battery inefficient it might be. :-) 3 Quote Link to comment Share on other sites More sharing options...
Zopper Posted January 25, 2021 Share Posted January 25, 2021 @HaligI wanted to check the battery voltage you had at the end and I see that the CSV is empty. It contains just bunch of semicolons. Can you fix that, or add the voltage at which you enabled home mode and then what you had at the end? Quote Link to comment Share on other sites More sharing options...
Halig Posted January 25, 2021 Author Share Posted January 25, 2021 At 66,9V start the first tiltback (-25º) > Need to activate Go home > 10,8 km after, at 62.1 V is the second and final tiltback. I have averaged the data from the last registers before the tiltbacks, since the voltage, as you imagine, is somewhat variable. I see that maybe the problem is that the file exceeds 3 MB and that is why it does not allow to upload it.

As all tours should now be available, would you share the link for this "research" tour? It would be interesting to look at the data charts.

The voltage drops linearly and the algorithm "stretches" at last. In the V11 it is practically perfect, in my opinion. I have been in the development group for the M365 Dashboard app for a long time, giving the data to implement a more real battery% calculation algorithm (the original is terrible and misleading), but it was not finally implemented and I already went to the unicycle, with which the subject is abandoned. Hopefully, in V11 I see that it is not necessary Quote Link to comment Share on other sites More sharing options...

Gj I'm poor and I spent all the money on V11 Actually, I want to do a consumption test based on speeds (to get a graph). I have to find a day with zero wind and a weekday for the track to be clear. We have an approach with experience, but I would like to see it in "laboratory" conditions (= pure entertainment) I also want to test a consumption test uphill, according to speed, to see what is the optimal speed of less consumption according to the slope. I really would like to know, to be able to increase the autonomy in cases of routes with strong climbs. I like to do long routes and it is important. 2 Quote Link to comment Share on other sites More sharing options...

4ngell Posted June 27, 2022 Share Posted June 27, 2022 Hello OP. I just got a cutout from my v11 and I saw a drop on voltage and current. Can you please upload de .cvs in case you still have it? I would like to compare voltages. The link to the tour in EUC world is also down. Thanks! 1 Quote Link to comment Share on other sites More sharing options...
Zopper Posted June 28, 2022 Share Posted June 28, 2022 @4ngell Do you need that particular record with no acceleration/braking? What are you trying to get from the data? Maybe a real data would help more. Quote Link to comment Share on other sites More sharing options...
