Battery Aging model rainflow counting

I have a SOC(t) profile for a Li ion battery in an electric truck. My model considers average SOC and depth of discharge (DOD) as cycling aging factors. I need to count the number of cycles in the SOC profile to obtain average SOC and DOD for each cycle. I'm going to use rainflow counting.

Before the actual counting, I'm going to do hysteresis (and peak-valley) filtering. Here is the SOC(t) profile before any processing.

How wide should the hysteresis gate be?

The amount of cycling is commonly stated in full equivalent cycles (FECs), by scaling the total charge throughput Q with the battery capacity C_batt in Ah:

Q = integration of current with time

FEC = Q/(2*C_batt)
