Hello Mark,
Please try looking at the TDD (Tab Disconnect Detection) feature which is on the bq27542-G1 or bq27546-G1 which is intended for this purpose.

The bq51221 does not have that information. It must be sent to it via I2C. A gas gauge, such as the bq27546-G1 has this information. The host can talk to both through I2C to transfer the information.
Regards,
Dick
