BQ40Z80: Charge inhibits if EV2400 gets disconnected

Part Number: BQ40Z80
Other Parts Discussed in Thread: EV2400

Dear TI support team,

actually I'm faced with the following issue:

I've finished the learning cycle for a 7S battery pack, which did work well.

During the measurements, the EV2400 was always connected, but now after all measurements are finished, I found out that the battery inhibits charging as soon as I disconnect the EV2400.

After disconnected, the battery allows charging for another ~10s and then it gets disrupted. Discharging the battery is always possible, regardless if EV2400 is connected or not.

In the datasheet, I wasn't able to find any hint for that issue. Maybe a wrongly set protection flag?

Thank you for your help in advance.
