I'm using this great tool called SavvyCan - will find out soon what bytes change during charging session as now I know what ID to look at.triangles wrote:Nice work! Glad to see someone working at figuring out how things work on the FFE.
So it looks like only bytes 3 and 4 are changing during charging session. Those must be displayed capacity.
B4 is counting up quickly after it comes to an limit b3 goes up and b4 starts from beginning
There is something going on with B6 also. To be sure I need to look at it when car is full and empty. I have a feeling B6 might much less accurate SOC.
So this was CAN capture from 1100s charging session at 32A 240V.
Session started at B3 0x01 B4 0xE5 - this gives hex 01e5 = 485 decimal
Session ended at B3 0x02 B4 0x58 - this gives hex 0258 = 600 decimal
So I think true value is div. by 10 - this would give 48.5% to 60% in 1100s - looking legit.
Once again I'll check those values when car is full and empty to be 100% sure.
I don't know how many kWh went into the battery at this time but I'll find out - will be playing with this capture file and this awesome tool more.
