The VIT measurement used for the OCV calculation is the last VIT measured before the OCV_CMD was received. The VIT value used for the OCV calculation needs to be a stable, not transient value. Before sending the OCV_CMD, the current must be stable and < C/20 for at least one second. The recommendations for the OCV_CMD used for ACTIVE mode is that the VIT remains stable from two seconds before the OCV_CMD is sent until the end of SOC_INT (see Figure 8-2).
