What is the typical SOC when left in LPR?   I have seen it charge to full (100% SOC)  in LPR last time, and now after 24 hours charging in LPR, my SOC is  not going past 36% SOC.


What should I expect in the LPR mode for  SOC?


Same 120 VAC granny cable used both times.


I will now change to a Tesla-Tap and see if that makes a difference, but I don't see why 240 VAC should change anything other than the time it takes.

I used my 240 VAC Tesla-Tap and now it charged up to 86% and stayed there, which sounds right. For whatever reason, the LPR mode didn't like my 120 VAC granny cable (it's NOT the cable that came with the bike).


But for a while, I got a BMS error with the Tesla-Tap connected. I forgot the error code, I didn't write it down. I didn't expect it to clear by itself, but it did. Now I have "Status Okay" under "service".


It also said something like "unexpected BMS error-contact Service". But I no longer have that error, so I assume all is now fine.


FWIW, I put on around  150 miles on my Energica yesterday, I AC charged it once (Virginia City)  and also fast DC charged it twice (Silver Springs and Carson City, NV )  with no problems and no error messages.


I got rather poor range yesterday, I assume because it was a bit cold and windy. The battery indicator was green even right after the fast charges, which I usually then have yellow.

My LPR keeps it spot on at 80%.
- using 240 V granny (Europe!)
- charge current set to 8A
- no SOC limit (LPR will take care of it)
- firmware .041 (LPR behaviour changed somewhat after most recent update)

Now spring has arrived here no more LPR for me 😁

Now spring has arrived here no more LPR for me 😁

I ride all year. But in Dec & Jan, I was riding in south Florida. 85F/30C down in the Everglades then. And not a lot cooler at night.


And they have charge stations in the Everglades Park.


See me here charging my 2017 DS here at 6.4KW.

My LPR keeps it spot on at 80%.

LPR mode was thought to be too aggressive but almost necessary now that a better understanding of the Energica BMS, depth of balance withstand is concerned, based on experimentation conducted last season (passive dissipation) 80-53% SOC storage for ~ 20 weeks was likely not best practice but didn't do harm either, now we know.

New practice is 80% SOC steady state, will definitely use LPR.  The noted characteristic is on recovery from storage the pack will balance fine on first charge whereas it takes several consecutive charge / balance iterations to get back to 100% when LPR was not employed.

Me thinks Energica taps the battery for keep alive asymmetrically which is fine and explains the importance for LPR - these bikes depend on good pack balance particularly if ridden below 40% SOC, duh that explains the yellow indication...no?

Great to see these video's released directly from Energica, this one is about LPR mode:
