576 +The BMS Main 3 device can control the charging/discharging contactor, which combines algorithms of charging and discharging contactor. It behaves as a charging contactor when “Charge request” or “Charger connected” is set, otherwise – as a discharging contactor.

577 -Charge/Discharge contactor has three algorithms of operation:
578 -
579 -* Dependent (on Charging and Discharging signals) - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals and behaves as Charging contactor if Charging signal is set, otherwise – as Discharging contactor;
580 -* Independent (Always) - Charge/Discharge contactor is always closed if there is no errors;
581 -* Independent (on Charge request or Discharge request) - Charge/Discharge contactor is based on its own controller that listen to Charge and Discharge requests.

590 -* Algorithm:
591 -** Dependent (on Charging and Discharging signals) - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals and behaves as Charging contactor if Charging signal is set, otherwise – as Discharging contactor;
592 -** Independent (Always) - Charge/Discharge contactor is always closed if there is no errors;

594 -* Delay before starting charging or discharging, millisecond;
595 -* Delay before stopping charging or discharging, millisecond;
596 -* Control the precharging contactor – a flag that enables control of precharging contactor while closing the charge/discharge contactor;
597 -* Emulate the "Charging" and "Discharging" signals – a flag to enable generation of "Charging" and "Discharging" signals when closing charge/discharge contactor;
598 -* Errors 1, 2 to prevent CHARGING through charging/discharging contactor, Errors 1, 2 to prevent DISCHARGING through charging/discharging contactor – bitfields to choose the errors which will open the charging/discharging contactor. This bitfields are combined by bitwise OR and intended to separate settings for charging and discharging processes;
599 -* Errors 1, 2 which affect the contactor only if battery CHARGING is detected – a bitfield to choose the errors which will trigger only if charging current is present. This bitfield is combined with "Errors 1, 2 to prevent CHARGING through charging/discharging contactor" by bitwise AND;
600 -* Errors 1, 2 which affect the contactor only if battery DISCHARGING is detected – a bitfield to choose the errors which will trigger only if discharging current is present. This bitfield is combined with "Errors 1, 2 to prevent DISCHARGING through charging/discharging contactor" by bitwise AND;
601 -* Switch off the charging/discharging contactor on errors without delay – a flag to protectively open the charging/discharging contactor without a delay. In the opposite case, when an error is detected, the charging/discharging contactor opens always with the delay “Delay before stopping discharging”.
