Hi Emma,

Refer to Figure 8-1 of TRM Entering CHARGE or RELAX Mode
Once in RELAX mode, the bq40z60 waits until an OCV measurement is taken, which occurs after: 1. A dV/dt condition of < 4 µV/s is satisfied, 2. After 5 hours from when | Current() | < Quit Current, 3. Upon gas gauge reset, 4. An IT Enable command is issued.
Refer to the TRM
