Total charge/discharge

Open MatinF opened this issue 2 years ago • 0 comments

Hi again,

I have another set of signals that I struggle with, the HV battery total charge and HV battery total discharge. Below is my payload: image

I understand both signals are 4 bytes long, but I struggle with what byte should be the 1st of the Total Charge signal. Can you help clarify this?

I seem to get reasonable values (maybe) when I start at bit 88 (counting the payload with the 1st byte in the picture (0x10) being ignored. I believe in your evDash you ignore both the 1st and 2nd bytes, i.e. both 0x10 and 0x13 in your 'counts'.

If I use this bit start I get a result as below: image

As evident, it looks "OK", but since the kWh/100 km is ~18.8 (i.e. 0.188 per km) and the trip is 6 km, I'd expect the net 'consumption' of kWh to be closer to 1.128 kWh. However, if I think of the TotalDischarge and TotalCharge, I would expect the delta between these to result in close to this value of 1.128 kWh. Yet, I get 0.14 kWh, which seems wrong.

Any idea where I might be going wrong in my logic/decoding here?

Below are details on my decoding implementation based on your work: image
