  The BMS Main 3 / BMS Main 2R 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.
--In **simple **mode precharge contactor closes af before the closing Charge of Discharge contactors
++BMS Main 3 device detects errors while pre-charging the load capacity by monitoring the current and voltage difference before and after contactors.
--BMS Main 3 can detect errors while pre-charging the load capacity by monitoring the current and voltage difference before and after contactors.
++BMS Main 2R device detects errors while pre-charging the load capacity only by monitoring the current.
--BMS Main 2R can detect errors while pre-charging the load capacity __only__ by monitoring the current.

  Also BMS can measure the power dissipated on precharge resistor and generate an error if it greater than configured limit.
