您好,CC1 is specifically made for charge integration, so for SOC calculations CC1 may be better. This integrates the current over a 250-ms window. CC2 will provide a faster instant current measurement with a new measurement every 3-ms. CC3 will take the average current from the CC2samples. So it would give the average from 1 CC2 sample to up-to 255 CC2 samples. These are all described in Section 4.3 Coulomb Counter and Digital Filters of the Technical Reference Manual.
