You are my hero  ;)

You plugged the thingie on the USB/heatgrip?

You don't have any error code of the dash when the indicators are flashing?

I think the range is quite good for an electric bicycle but i wonder if you can order performance parts like pedals  ;D

End Of Charge Cycle

https://youtube.com/shorts/xvFtqBBmZ_Y?feature=share

That video does not seem like expected behavior.  My 2023 rebelle will show that balancing message as it approaches 100% and when it hits 100% the charging process turns off and the cable lock is released, no charge is complete message.  The screen goes dark if I had the bike keyed off during charging.  When I turn on the bike, I see 100% charge.  No error or fault message.

Same on my 22 Ribelle RS and the tech's confirmed that the real indicator of the end of the balancing is when 100% shows on the dash

No once you get 100% it means that the battery is balanced

It's already a PITA no need to wait for a confirmation screen ;)

Same here.

About the small voltage difference it's normal. A balanced battery a 100% is indeed balanced at 99.99% there's always a small tolerance

My bike had a connector issue inside the battery that prevented a full 100% charge. It took us like 1 year to find this issue so basically the bike wasn't balanced for at least a year.

To give some credit to my dealer, this issue is very rare and couldn't be found easily. There's no special error code and the main symptom was that the bike shut off. It only happened 2 times in one year. First time, we thought it was a firmware issue and i thought it was resolved. When i was "balancing" my battery i wasn't to worried to see 98% the next morning and thought i had lost 2% overnight so i thought i was doing the right thing

The second time the bike shut off, i couldn't even charge DC so that why we did some freeze frame and send them to the factory. Then Energica Italy took control of the bike and runs a bunch of test, we made some also and they found that my issue was hardware related and that i was a very rare connecting issue inside the battery. That explain why they flew 3 techs from italy to fix it instead of changing the battery pack. I can't blame my dealer, he's great and this issue is so specific that he couldn't find it "alone"

About the dealers and balancing, most of them aren't aware that the bike shut down after 1h even if it's unbalanced. As us, they thought they were doing the right thing just by putting it on charge without limit every now and then.
For exemple, when the guys from energica explained this to my dealer, he put the demo Ribelle to the test and had to do 4 cycles do reach 100%  ;D

Again, for me the fact that the bike shut off after 1h even if balancing isn't done is a bad design choice and the fact that even the dealers aren't aware of it isn't really clever.

However, despite this, i'm still amazed by the level of customer service from my dealer and Energica. They put a lot of effort to find the issue, once they found out what it was, they flew the week after from italy to fix it so ok there's sometimes some issues or mistake but they care of them.

So how many unplug/plug cycles should it take to get the balance complete and 100% SOC, I think I'm up to 6 times in 2 days still not there yet.

My battery was really unbalanced and reached 100% just this morning after like 15 cycles of plugging/unplugging. So it's tedious but at the end it is working as they said

I drove small distances and without putting too much pressure on the throttle

I shared more or less all your opinions before discussing until the techs from Energica explained to me how their bike behave and shown me a deep analysis of my battery life stating that my last full balance was in july 2022. Then they told me that i need to plug/unplug/resume again and again and that my battery will only be fully balanced when 100% will show. It's not dealer "bullshits" those guys are working at the factory so i assume they know their bike better than anyone.

To be honest, i think it's a bad design decision to made the bike start balancing so "late" in the charging process when you implement a cut off after 1h without juice.

All in all it's not a big deal, but i just wanted to point out that sometimes we may think we balanced the bike properly but it's not always true

I used to have like 97% so i thought 3% isn't a big deal but it's a bit more complex because 1% is not equal to 1 cell.  For exemple, a Tesla 85 Kw Battery have 7104 cells, so our 21.5 Energica should have around 1700 cells so 3% is around 50 cells that need balancing.

In one hour, those cells will not be able to be balanced (they told me that it could take a few days pluging/unplugging to balance my battery back from 97% to 100%). So if i don't force myself to do it correctly once, the balancing will slowly get worse. The more i wait, the more cells will need balance and the more time it ll take.

To be honest, i'm not a balancing addict also, i was just pointing out that i was thinking that i was balancing my battery correctly and i was wrong because i wasn't aware of this "cut off after 1h" thing.

So if you plan/wish to balance it to 100% you have to reach 100% on the dashboard otherwise the balancing isn't perfect.

@Valen: I have a complete set of nice indicators here waiting to be installed as well. So I promise, I will die trying  :P

Just as @Demoni suggested I looked at the fuse box yesterday and attached some pics. The fuse box is underneath the right top fairing which is helt by 5 screws only.

There are 7 fuses, according to my manual (RIbelle RS '22) they are for the following functions.
1. Vehicle control unit 30 A
2. Power train controller 10 A
3. ABS valves 15 A
4. ABS pump 25 A
5. Charge manager, connectivity hub, OBD 10 A
6. USB and heated grips 10 A
7. E-Keyless 10 A

The No.7 totally surprised me, because I do not have a keyless system! Does anyone know why? Is this circuit active even without keyless?

My plan is to tap into the No.6 circuit just at the fuse box with this wire tap    https://www.posi-products.com/posiplug.html.
Does that sound right? I am open for other suggestions!

Cost cutting they just don t bother developping another fuse box  :P

I have a 2023 Ribelle and have seen it start balancing as low as 90 percent before.  I want to say I've seen it start in the upper 80's but want to verify that first.
I have not paid attention  to the balancing but have seen it turn off at 99 percent only twice really.
Once was after a few CCS charges and hopping right back on, and riding the bike hard, so yah there could have been an unbalance.  The other was an overnight charge that was a fast charge followed by an AC charge to finish the last say 20 percent of it, I woke up the next morning turned the bike on and it said 99 so can't say for sure how it got there.

I can't see that I seen the hour turn off.  I have charged my bike at 115 ish volts before, (that is the voltage when I plug it directly into my one solar panel array) and it's been at balancing for more than an  hour at times.

I'll keep an eye on it better and see what I observe.
Thanks for this post, im interested to see what's up now!

Aaron

When there's still some charging going on (the top number on the dash) the bike will not cut off after 1h.
The bike will cut only after 1h at 0.0 which happens when the bike doesn't charge anymore but is still balancing the cells.

Following the discussion with the techs, there is no "charging complete" or "balancing complete" screen which is in my opinion really dumb.

The only way to make sure that the battery is really fully balanced is that the bike is indicating 100%. For your info, mine was badly unbalanced due to the separate issue that i had and they told me that acheiving a full balancing will take around a week (unplugging, plugging and starting over)

I already see an increase in balance so it is working (slowly).

But to be honest now that i know how it works i think i ll cancel the SOC limit for the future ;)

Three technicians flown in? Colour me impressed.

Yep changing the defective connector inside de battery was a pain in the .... as my dealer said. They had to remove the battery, dissasemble it partially..

 They were supposed to be "only" 2 at the beginning but they took the opportunity to do a bit of training to the mecanics at the dealer also.

I'm on the last Firmware but in this case it's irrelevant. Long story short, i had a defective connector inside the battery (don't worry it's quite rare) so balancing was impossible for a few months. It was a hardware problem, not a software one so it's not related to FW version

If you balanced your battery on a regular basis, 1h is enough so you don't see any problem. However, if you didn't (or can't) balance it correctly for an extended period and the bike will still shut off automaticaly after 1h (even if you need more).
Basically you just need to unplug, plug back in and it ll resume the balancing for another 1h.

The info couldn't be more accurate as it comes from the 3 techs from Energica factory that flew to Paris last week to inspect and repair my bike.
