ltdorn Posted July 5, 2019 Share Posted July 5, 2019 Description: when planning a trip with a chevy bolt and pulling live data. the planner prepopulates with 114% battery degradation and results in no plan generated because battery range would be zero. Link to Plan: screen capture attached. Replication Steps: Replication Steps If applicable Remember, the more detail you can provide in your bug report, the faster we can fix it!

Jason-ABRP Posted July 7, 2019 Share Posted July 7, 2019 Very interesting. Speculation online is that Chevy changed the capacity PID on the Bolt to do something else in the 2019. In that case, you may want to just remove that PID from logging until a new one is identified. Link to comment Share on other sites More sharing options...
mazdaspd05 Posted September 12, 2019 Share Posted September 12, 2019 I had the same problem, but once I changed it back to 5% manually it has stayed at 5. Link to comment Share on other sites More sharing options...
dborn Posted November 14, 2019 Share Posted November 14, 2019 (edited) I'm having the same issue on my 2019 Bolt. I read on Reddit that the car needs a few discharges below 10% followed by full recharges to 100% to "wake up" this PID. I don't know if it's true, but since my car is not even 2 months old and has a little over 3000km on the odo and I've never gone lower than about 25% charge yet and only charged to 100% a couple of times, my experience to date seems to be compatible with that theory... even if not very conclusive. I guess I'll need to push it a little more to find out. Can anybody prove this theory wrong? Edited November 14, 2019 by dborn Link to comment Share on other sites More sharing options...
coledavidson Posted November 15, 2019 Share Posted November 15, 2019 I'm also having this issue on my 2019 Bolt. Do we have a workaround yet or is disabling that pid still the best option? Link to comment Share on other sites More sharing options...
Jason-ABRP Posted November 15, 2019 Share Posted November 15, 2019 Unfortunately I don't have a 2019 Bolt to test with, but at the very least I've updated the API so that anything over 100% SoH is reported as 100% to avoid causing problems with the planner.

Daniel Thanks! Best place to start is the rumor that doing a "calibration cycle" will fix the PID (get to low Soc, <10%, then charge to 100%), if we can get confirmation that this correctly fixes the PID, then we're set! Otherwise we'll have to do a lot more work. Link to comment Share on other sites More sharing options...
dborn Posted November 18, 2019 Share Posted November 18, 2019 I'm on it! I usually don't drive that far so it might take a few weeks. I will report back here once it's conclusive. Daniel Link to comment Share on other sites More sharing options...

dborn Posted November 24, 2019 Share Posted November 24, 2019 Got one down... Drove it all the way down to flashing orange "Low" display (Torque Pro said something like 7.8% SOC raw). Car display said I used 60.4KWh since last charge! It's currently being charged back up to 100% I'll try to do it again ASAP. Hope it will "wake up" that PID...

dborn Posted December 30, 2019 Share Posted December 30, 2019 Got the second one down yesterday. Brought it down to 5.7% and back up to 100% straight. This morning I check with my OBD2 dongle and Torque. Didn't change anything, unfortunately. I'll try another time when it's convenient. Not having high hopes though.

Jason, as a matter of fact, the incorrect value is -114% so it's not above 100% so I still need to override the value manually when using the live data. Could you change that to not allow values outside of the valid range 40% to 100% and then use 100% ? Link to comment Share on other sites More sharing options...
Jason-ABRP Posted December 31, 2019 Share Posted December 31, 2019 I added another sanity check which ignores negative SoH. Just to double check, what does Torque display for readings of the battery capacity PID? Link to comment Share on other sites More sharing options...

Jason-ABRP Posted January 1, 2020 Share Posted January 1, 2020 Well, that definitely lines up with -115%. I'll pull some data and see if there's any trending, perhaps the computation the PID list uses is incorrect, but that PID still provides health / capacity data.

TomTomZoe Posted February 18, 2020 Share Posted February 18, 2020 The PID for capacity has changed since the 2019 models of Bolt and Ampera-e. The PID shows now permanently 8,6kWh. In the german Goingelectric Forum they saw the same issue with 2019 Ampera-e. Link to comment Share on other sites More sharing options...
