the0r1st Posted May 25, 2021 Author Share Posted May 25, 2021 just got an update to 2.071 Quote Link to comment Share on other sites More sharing options...
FinRider Posted June 10, 2021 Share Posted June 10, 2021 Uhh I did not even realize there was an update out.... I am still on 2.06 Any additional info on this? Quote Link to comment Share on other sites More sharing options...
Wrd Posted June 22, 2021 Share Posted June 22, 2021 I started out on 2.07 A few months ago. Recently I began to notice some infrequent phantom power drains, after fully charging. (oh, that reminds me I need to go see if the wheel was topped off and unplug it). I asked around and heard that 2.08 might address this very problem. But it was either released and removed or hasn’t been released yet. I skipped the 20.71 release because The version number anomaly looked like a mistake. Who knows? Maybe that’s the firmware update I need. Quote Link to comment Share on other sites More sharing options...

I am on 2.06 and I also have the "phantom" power drain after full charge. EUC world and darknessbot both show a 0.3A draw. If you power cycle the EUC after full charge, it goes away.

Wrd Posted June 23, 2021 Share Posted June 23, 2021 Nice. I’ll try that. It’s annoying to head out for a ride at 92% when you know you topped it off. Quote Link to comment Share on other sites More sharing options...
Purplecycle Posted June 23, 2021 Share Posted June 23, 2021 Same here with the power drain...quite annoying, as I leave it charging overnight only to find it at 90-something percent in the morning... hopefully this issue will be solved in the next firmware update...

FinRider Posted July 6, 2021 Share Posted July 6, 2021 I just wrote about this in our local forum, so I might as well share my "charging" experience in this thread. I usually use my 5A charger, but I did this test with the stock charger. Start charging. Amps drawn as shown in EUC world is 2.6 - 2.7 (actually shows a negative -2.6A) Amperage starts to decline once voltage reached 84V Once 84.5V is reached, the amperage goes further down. When it hits -0.5A the green light on the charger comes on. This is where I believe the "balancing" of the cells happen The voltage stays steady at 84.5V and the amperage slowly goes down to 0. Once "fully topped off" the wheel starts to pull 0.3A --> my belief is that this is the bluetooth connection that stays active. This 0.3A "drain" is continuous. Unplugging the charger and replugging it does not help --> amperage drawn stays at 0.3A. I tested this when the voltaged had been consumed down to 83V by the 0.3A draw. Powering on the EUC and then powering off the EUC stops this draw. So I have taken it as a habit that I cycle power on the EUC as soon as it is fully charged. This way I can ensure that I have 100% battery when I go riding. Does anyone know if there is a setting for the wheel to put a timeout on the bluetooth? 1 Quote Link to comment Share on other sites More sharing options...

Or both? 18 minutes ago, FinRider said: Amperage starts to decline once voltage reached 84V Thats the end of the C(onstant)C(urrent) phase and start of the C(onstant)V(oltage) phase. Balancing starts around this point. 18 minutes ago, FinRider said: Once 84.5V is reached, the amperage goes further down. Current declines (theoreticly) exponential. 18 minutes ago, FinRider said: When it hits -0.5A the green light on the charger comes on. The ks18xl has 6 cells in parallel. Manufacturer recommendation is to stop charging at ~50mA per cell. So 6x0.05=0.3A. Given your lateron mentioned quiescent current this seems about a great moment to stop charging! Maybe with the measurement inaccuracy some a bit longer charging would comply with the datasheet? 18 minutes ago, FinRider said: This is where I believe the "balancing" of the cells happen As written above this already starts once the battery reaches 84V. But here balancing still goes on. It was and is still recommended to leave the battery on the charger after it turned green for balancing, but imho that's ineffective and more stress for the batteries as it helps.

Maybe @Seba can implement such a power cycle for KS wheels in the EUCWorld charge control? 18 minutes ago, FinRider said: Does anyone know if there is a setting for the wheel to put a timeout on the bluetooth? There is a general wheel timeout that can be set with all the apps. But i fear that this does not help as afaik the maximum timeout duration is about 2h and people reported severe discharge of their KS wheels... 1 Quote Link to comment Share on other sites More sharing options...

With my 16x, the entire control board is powered on at this point. Later firmware like 2.07 is supposed to restart charging if the voltage gets low enough but perhaps more importantly it “seems” to power off the control board when the charger is unplugged. I say “seems” because the headlight flashes and the speaker goes ‘whump’ softly the same way it does on a button power off. But I haven’t looked for phantom power drain and also power cycle the wheel after unplugging. Habit now! I should see what happens to the control board LEDs next time I have it open.

Active Bluetooth connection doesn't justify such high power consumption; 0.3 Amp at 84 Volts gives 25 Watts. My KS-18XL draws 0.07 A at the end of charging, with EUC World connected. 1 Quote Link to comment Share on other sites More sharing options...

I have started to take it as a habit to disconnect the charger as soon as it goes green.. when the "load" to the batteries is less than -0.5A and before it startsa pulling the 0.3A. Annoying, but it works for me. 1 Quote Link to comment Share on other sites More sharing options...
jrhz06 Posted July 31, 2021 Share Posted July 31, 2021 Just did a firmware check on my S18. I’m at 2.06 and it says I’m current. Why doesn’t mine show 2.07 as available? 1 Quote Link to comment Share on other sites More sharing options...

If you’re on iOS, try: softtuner As an incurable tinkerer (ie I didn't need to, but did it anyways!), I used softuner to push 2.07 last night, as that firmware release isn't an option in KingSong or EUC World as stated above. I did notice a newer version (2.071 or some such), but didn't want to push my luck... I've not noticed any difference as yet, but have only given it a brief test ride (after calibration). No issues upgrading. Thanks for the pointer to softuner, @Wrd! Edited September 11, 2021 by WillCO Grammar! Quote Link to comment Share on other sites More sharing options...
Tawpie Posted September 11, 2021 Share Posted September 11, 2021 off topic note about 2.07 — it might make unlocking your wheel difficult or impossible. I was fooling around with locking the wheel and EUCW couldn't unlock it, I was able to unlock with the iOS KS app though. This was on a 16XS.

FinRider Posted September 15, 2021 Share Posted September 15, 2021 Has anyone found any release notes on the 2.07 firmware? I am curious to a) what it includes and b) why is it not available through EUC World @Seba? 1 Quote Link to comment Share on other sites More sharing options...

WillCO Posted October 3, 2021 Share Posted October 3, 2021 (edited) Sooooo, tinkered w/2.07, then dropped to 2.05 (wanted to see what the handle acted like at that .ver), then decided to go back to 2.06 tonight. Using the Softuner app, I noticed that .ver 2.09 was available, so what the heck, installed it! Only rode around the block (in the dark, no gear, so very cautiously), and haven't noticed any difference. Firmware mentioned "Handle Improvement" or something along those lines, should have taken a screen shot. Nothing else mentioned....
