473 473  The BMS Mini device can control the charging/discharging contactor that is used to both charge and discharge the battery.
474 474  
475 -Charge/Discharge contactor has three algorithms of operation:
475 +The charging/discharging contactor combines algorithms of charging and discharging contactor. It behaves as a charging contactor when «Charge request» or «Charger connected» are set, otherwise – as a discharging contactor.
476 476  
477 -* 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;
478 -* Independent (Always) - Charge/Discharge contactor is always closed if there is no errors;
479 -* Independent (on Charge request or Discharge request) - Charge/Discharge contactor is based on its own controller that listen to Charge and Discharge requests and closes if one of these signals occurs.

This bitfields are combined by bitwise OR and intended to separate settings for charging and discharging processes;
504 -* 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;
505 -* 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;
506 -* 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”.
