Lets take a poll, who has the most miles/years on their FFE?

So folks know, 100% is actually 95% SoC on the pack.

Good to point out.

All of my post was dealing with what was reported on the dash, which is what your typical driver would deal with.

Perhaps it might make things clearer if we were to use better terms. Such as "SOC actual" for the pack, and "SOC gauge" for what shows on the dashboard display.

Kind of like pressures specified as "PSI gauge" when they measure pressure relative to atmospheric air pressure.

What I was going for was SoC Pack vs SoC display, which is synonymous with actual and gauge.

Hello.

Thanks for the information.

I think the voltages are different because of the current.
Although I can't explain the low voltage at 94.0% and 93.8%.

The value HBC is probably Hybrid Battery Current.
Where no sign means discharge and "- sign" means charging.

What I got from my record:

SoC 95.00% 350.20V 4.06V/Cell 14°C

SoC 52.31% 313.28V 3.64V/Cell -3°C
SoC 39.58% 313.00V 3.64V/Cell 10°C

SoC 32.50% 306.13V 3.55V/Cell 4°C
SoC 32.22% 303.11V 3.52V/Cell 4°C
SoC 24.44% 305.55V 3.54V/Cell 12°C

It is interesting that the SoC depends on the voltage and also on the temperature.

~313V means
SoC ~52% at -3°C,
SoC ~39% at +10°C.

I read somewhere that the 2013 FFE version has LG NMO pouch cells.
I don't know if this is also the case with the 2017 FFE version.

Here with "SoC" I meant the value "H_BATT_CHAR in FORScan" which apparently indicates the BMS SoC.
The value "BAT_CHAR_DISPL in FORScan" is approximately the value shown in the car display.

100% BAT_CHAR_DISPL = 95.00% H_BATT_CHAR,
~0% BAT_CHAR_DISPL = 8.50% H_BATT_CHAR.

Today, Saturday, a new measurement was added
14% BAT_CHAR_DISPL = 20.39% H_BATT_CHAR, 303.34V, 3.52V/Cell +8°C,
EtE 3.872kWh

Currently ~26.300km, Full ~27.6kWh (~95% SoH at +8°C)).
