Could you describe the meaning of this binary sensor in a few words? I would like to try to improve the naming of these 4 status sensors to be more explicit.

I'm doing some experiments with the PACE BMS to elucidate the behavior, it's new to me.

Alright! Let me know as soon you know the differences between the flags.

OK, now it's clear:
The Mosfet CHG and DCHG flags turn the MOSFETs on or off depending on the state of the battery protection and allow the battery to be charged or discharged.
The other flags are operating flags and signal the actual operating status of charging or discharging. A corresponding current must also flow for this. The battery charging process flag also enables balancing.

OK some additional experience with PACE BMS:
If over voltage protection is reached, the SOC is set to 100% and the remaining capacity is set to design capacity.
After arrive of overvoltage protection release voltage, the specified protection flag is cleared, but not Bit16!
As long as the protection-flag bitset is not equal 0, the balancing works also (Bit16 is on).
Bit16 is cleared, if the Mosfet-switch get state enabled.
Something is my smells
