Car Scanner SOH readings

[SueSoulEV]

I have a 2017 Soul EV with all original HVB components. Winter temps here are a few degrees above freezing (Pacific Northwest), and the car is now getting max 75 km on 100% charge. I have tried to get some info using the Car Scanner app and Vgate iCar Pro dongle. There are two State of Health percentages given, #1 and #2. Does anyone know why there are two values? Is one the HVB and the other is the 12V battery? If so, which is which? Or something else? I will include a screen shot. Thanks for any help!

Mine shows SOH 1 = 110% and SOH 2 = 60%

My guess too is that SOH 1 is HV battery and SOH 2 is 12V battery

SOH 2 at 60% is quite believable for the 12V battery, as it's about 4 1/2 years old

SOH 1 at 110% seems a bit optimistic for the HV battery - it implies a capacity of 33 kWh, which suggests it has not used much of the top buffer after nearly 7 years, but SoulEV Spy reports 100%, and we know it never exceeds that, so it's not impossible. The reading was taken 3 months after the BMS update which appears to limit charging to about 27 kWh, so it may have had an effect on BMS values read by Car Scanner.

IanL - Thanks for your reply. My warranty expires at the end of Feb 2025. I have arranged to have the car checked by an independent mechanic who specializes in EVs (GreenTec Auto) so I will have some solid data to take to the dealership if necessary.
