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.

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;

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”.
