Battery charging / SoC
Posted: Fri Sep 27, 2019 5:06 pm
Hi Guys
I have an Everest MY16. It came with a crap battery from the factory which would regularly leave the car unable to start. After a bit of drama it was eventually swapped out by the dealer with a Century batt.
While I haven't had any starting issues with the new battery I have recently started monitoring SoC and 'AMPs in' via Torque Pro. I have noticed that the battery rarely gets above 75% SoC and that the charge current seems to drop right away about 5 mins after inital start. Upon starting I see 50-60 amps for a brief period then it settles to about 2amps. The voltage appears to be 14.4v while the car is running (based from cig socket meter).
I have tried various dual battery settings via Forscan like disable, 70,80,100% but doesn't seem to change. I have also disconnected battery, done a maintenance charge via external charger, then reconnected and a BMS reset. SoC held around 90% for a good week then dropped back to <80%.
Is this 'normal' or do I again have some sort of battery issue? Or is this something else like TorquePro measuring wrong. I checked my PiDs from the list in here and is the same.
