++The BMS Mini S / BMS Mini device can control the precharge contactor. The precharge contactor is used to charge the intermediate capacity with low current and usually placed with the limiting resistor in parallel to charging or discharging contactor.
--BMS Main 3 device detects errors while pre-charging the load capacity by monitoring the current and voltage difference before and after contactors. Also BMS can measure the power dissipated on precharge resistor and generate an error if it greater than configured limit.
++BMS Mini S / BMS Mini can check the preacharge process **only by monitoring the current**.
++In **simple **mode precharge contactor closes a "Precharge time" before the closing of Charge or Discharge contactors and opens after the same amount of time after closing them.
++
++In **enhanced **mode precharge contactor will wait until the current of voltage difference requirements are met and close the Charge or Discharge contactors only after that. If waiting time is greater than "Precharge time" value, an error will be generated. Precharge contactor will open after "Precharge time" after closing the Charge of Discharge contactors.
