First off, are you sure that the link down event correlates to you losing power? It itself isn't an error per se, but it happening when it shouldn't be is of course a fault. However as you've seen from the second set of logs the link going down alone isn't necessarily noticeable. When you do lose power you're also getting a bunch of other errors and they all seem to be related to overvoltage and overcurrent, and the contactor welded error also isn't good (I think someone explained to me before that it doesn't necessarily mean it is physically welded, but there is something preventing it from opening). I also notice that the "B" voltage is 100V which seems reasonable and lines up with the actual pack voltage reading, but the "C" voltage is anywhere from 113V to 138V. I'm not sure what B and C actually refer to but considering the battery only goes up to 116V that does seem a bit iffy.
More info about the error codes here if you want to try and make more sense of it: https://zeromanual.com/wiki/Gen2/Motor_Controller/CAN_Diagnostics
EDIT: Probably should have clarified, does the time stamp when the link goes down and you get all those errors actually line up with the time when you lose power. There could be other causes, when it was happening to me it was due to a faulty throttle and there wasn't anything in the logs that pointed to it.

Did you check the connectors for the CAN bus also? Maybe it's a loose, dirty, or corroded.

Any one encounterd Sevcon CAN Link Down before?
The first time it happend; the bike was charging overnight; So i did not notice it. Than it happend when I was driving. I suddenly lost power. Because the Logs showed the SEVCON CAN link was lost; my first tought was that it could be a broken wire. I checked the wiring; and I could not find any damage. I also tried to see if the CAN Link would go down; if I was fumbling with the CAN wirering. Sadly this is also not the case... I'm a bit afraid that my SEVCON is dying.... Did anyone have a SEVCON dying in 5 years or after 21.000 km? the first time it happend to my bike was apperently when it was charging. But only now I am noticing it when i'm driving.

Are there any Energica bikers who have ever fitted a 'non-original side or middle stand' to an Energica Eva SS9 (the 14kw version... without +) ?
I've had problems with the threaded screws in the battery block before. I suspect that my side stand is slowly but surely bending. 300 kg is simply too much. My favourite would be a non-original middle stand Thx |
