RE: 2022 Energica Eva Ribelle that can't read it's own battery level
Good day,
Starting at home at 80% SOC, I rode ~30 miles, then it idle for 4 hours, and then went to ride home.
5 miles into my trip home (at around 55% SOC), the Battery Reading went to 0% immediately.
Gave me Diag Code P1021 (HV CONTACTOR ERROR (I think)) and let me Limp-Mode home 25 miles at 40-50mph.
Tried power-cycles and RESETS (Mode + SET Profile for 10sed)... runs through relay clicks, but same 0% battery reading.
Says it charges, but always 0% battery reading even after an hour of charging at 1kW,
Can only ride in Limp-Mode.
I checked the fuses, and wiggled the connectors... when I had it apart, it threw a whole bunch of Faults (but that may have been related to missing "tank" cover LED module). After clearing those faults, it never threw another fault.
About 1000miles ago, I had it serviced and they upgraded the firmware.
I'm at a loss... any ideas?
Thanks,

I expect you contacted the service facility that updated your firmware. What did they say?
-
They're closed on Sunday and Monday... they open at 9AM EST tomorrow... so I will give them a try then.

Did you try a reboot of the bike?
With the bike on press and hold the center mode button and the set button on the back of the left control. Hold these till the screen goes black and the bike will restart.
At least that will reboot my VCU (Vehicle Control Unit) in my SS9-. It can solve some weird problems in a few seconds.

Yeah, tried that several times. All of the relays click (like normal), but still the battery reads 0% after.

I had something similar happen to my SS9-.

Thanks Don... My fan seems to be working when it's charging, just doesn't update the SoC value on the screen. I will double check this when I get home though.
Thank you,

I didn't think your issue was fan related. I don't even think mine was. It's just that they both happened to me at the same time.

I see. Your SoC display was not updating with a correct reading. And my displayed SoC is stuck at 0%, so I see how it could be related.
Sadly, power-cycles, resets, and charging does not un-stick mine.
Mine has been stuck at 0% for a few days now (so I can only ride in limp mode).

I take it you never tried to charge it to 100% SOC. I would leave it charging for a while even after what would normally be 100% SOC and see what happens. It probably won't fix anything, but worth a try. That is what seemed to fix my issue, but the only error I had was unrelated (the fan open).
Your contactor error makes it sound a bit more serious, but I would try the extra-long charge anyway. Nothing to lose.

Thanks for the advice Don... I didn't try that yet since I was afraid of over charging cells if it couldn't get a correct reading.
I left it charging over night (really slowly 120vac at 5amp).
It didn't budge off of 0% for a long while, but now it's at 22%.
Now that it's not at zero I will cycle it a few times and charge to 100% like you suggest.
Thanks again,

Good to know that you're off the 0% SOC. Looking at your previous photo of charging 8A (1kW), the bike estimates a full charge in 8,3 hours, which is 8kWh of capacity useable to 80%, so 10kWh of useable capacity at 100%. If the battery capacity useable is at 16kWh (what it should be) and you're at 22% SOC now, you need at least 20 hours of charging at 5A (600W). Why so slow?
-
I was just being overly cautious (since I didn't know what the failure was).
Ever since I got the firmware update last month, the time estimates for "charge complete" have been even worse than it was (and I found it was pretty inaccurate before (especially for times greater than a few hours)).
My current theory is that one of the cells became dangerously unbalanced from the others (and as a fail-safe the firmware brought the displayed SoC from 50% to 0% immediately.
...just a theory.

Do you still have the Code P1021 error message?
-Don- Reno, NV

No error messages so far. ??👍

I think you will have your bike fixed after a couple of extra-long charges.
I don't think the BMS will let it overcharge regardless of your SOC.

Good to hear that you are good to go again!
No worries, the charge-time estimation is totally nuts since the xxx042 update. Also range estimation is messed up. You are not alone with that problem.
Luckily it does not appear to affect performance, in my view probably just some factors were messed up. Annoying sloppy quality control though.
Reported that to my dealer who forwarded it to Energica. No answer yet.

Thank you Don and jotjotde.
I consider this issue closed, but wanted to add one more CLUE for someday finding the root cause:
After the first cycle, riding to drain the SoC for the next charge, I parked it at 41%. When I started it back up to move it to the charger, it displayed 91% SoC.
The missing 50% that magically disappeared 4 days earlier miraculously reappeared.
When I put it in drive it gave a status message ( I wish I took a pic to get the exact wording ), that said something like:
"Charge to 100% to allow for cell balancing and to Align SoC"
I did charge to 100% (which I typically do every 500 miles or so (80% SoC my typical overnight charge)).
And again, no error codes were found in the diagnostic screen (haven't check OBD2 yet, but don't expect anything since I didn't see an actual error since getting un-stuck from 0% SoC).

What that message said was to ride until you're in the limp mode at 0% SOC and then charge all the way up to 100% SOC. IOW, do a full charge from empty to full at once. That will calibrate your SOC.
It's an expected message after such a screwy SOC is displayed.

Got it!
Makes sense. I will do this ASAP.
