Title: EVA Ribelle - WattHrs/Mile Display
Post by: PWM on December 09, 2020, 06:40:28 AM
At stand-still my Ribelle indicates 10,460.0 WatHrs/Mile but otherwise indicates correctly when moving, shows zero under regen and average reading seems unaffected, can anyone confirm similar effect?

It must think it's moving very slowly...

This is normal when it's stopped.

Thanks for confirming - obviously a programming bug.

Is it worthy to compile a bug-list for future correction?  Perhaps a dedicated thread, concise in format that we can forward to Energica?

I've noticed a few quirks which are easy to shrug once understood but still annoying...it detracts from the otherwise solid functional experience, IMO.

Yes the Ribelle has a lot of software related issues, at least mine does. Agree on a dedicated thread for this where people can post what they are seeing. I am sure some are more common than others. Right now it seems Italy is really slow at reacting to the software issues.

Is it really a Software Bug? The number it displays is just the maximum number it can display, so if you are not moving but still draw power you basically use infinite WtHrs/Mile

You are right. They could have displayed it as '------' or so, but I don't mind the current display :).

WattHrs/Mile factors power dissipation hence efficiency - the lower the indicated value the more efficient the bike is operating.  At stand-still we are dissipating zero power for traction control.   Standby power for lighting and such is not factored.  The displayed value makes no sense except it is unique for stand-still - I can understand the acceptance to this but it doesn't mean it's correct.

Well it is correct from the point of view of the definition. If you are standing still then it will take infinity of power to do 1 mile. And indeed, even if energy draw is small, you still divide by 0

reini, It is probably a bit like when you plug into L1 to charge. It will show as 9 hr 59 min till fully charged when in reality it will take over 24 hours to  fully charge. It usually isn't until it charges up to 60% SOC that it starts to drop below 9 hrs 59 minutes. I expected a lot better from Energica.
