Drained my HV/Traction battery to 1 bar in neutral by accident while parked

Title mostly says it but I also went over a muddy trail before and after doing said stupid thing in neutral/idle while accessories were on (AC/Medium Fan).

Gave me the info message saying car won’t charge in neutral and noticed it was at 1 bar when it happened, put it in park immediately and let it recharge the battery.

Symptoms after that are as follows:

Sluggish/Slippish lift offs from red lights.

ICE will kick back on after car does it warm up on start after reaching 100 degrees and will continue to stay on, water temperature reached 205 degrees on my ScanGauge || reader because the ICE continued to run while I was in some small town lake front July 3rd with traffic going a snails pace due to firework events, was stressing the whole time because usually kicks into EV mode when going a snails pace, nope, ICE was still running since it started up from park 10 minutes ago from the beginning of the drive.

12v Battery reads @ 14.1-14.0 volts when the car is driving, parked and or idling, nothing changes this voltage reading. Used to be another number before this incident, 15ish volts in normal.

EV mode finally kicked in when traction battery was at 1 bar AWAY from FULL bars, so like 15 minutes of driving is when it finally kicked in and started acting the ways it’s suppose to.

Did I hurt the 12volt battery? Is ice constantly running to maintain and charge a new imbalance it incurred with said situation between the charging the traction battery does for the 12 volt when 12volt battery needs to be charged? Is this imbalance able to be rebalanced by over charging the traction battery down a hill so it hits actual full bars?

Just took a pressure washer to the underbody of the car to get rid of that mud which was covering up everything.

Going to over charge the traction battery down some hills and see if it fixes the imbalance otherwise I’m assuming I will need to trickle charge the 12volt back to its normal self.

 

Everything went back to normal the night I pressure washed the underbody and over charged it beyond 8 bars of HV battery.

 

Yeah symptoms went away after a long drive to work down some hills on top of pressure washing the underbody. Pretty sure it was over charging downhill that corrected it unless the mud I washed off was interfering with something.

 

I think the 12volt battery took a hit more than anything because symptoms went away after a long drive to work down some hills that I was able to over charge the HV battery on.

weird but all good now, thanks for the input guys.
