General 

The MB Advanced Control, control unit (N175) has two interfaces for battery management units:

• LIN interface
• I/O interface

LIN interface 

The MBAC can monitor the state of charge of the secondary battery for each battery management unit. To do so, a battery management unit must be connected to the MBAC via the LIN interface.

The MBAC can read out the voltage of the secondary battery with a specific accuracy in volts for each battery management unit. To do so, a battery management unit must be connected to the MBAC via the LIN interface.

I/O interface 

The MBAC can read out the state of a 12 V charger (active or inactive). To do so, a 12 DI_Batteriemanagement_12VV charger must be connected to the "DI_Battery_Management_12_V_Charger" interface and be controllable.

The MBAC can read out the state of a solar system (active or inactive). To do so, a solar system must be connected to the "DI_Battery_Management_Solar_System" interface and be controllable.

The MBAC can read out the status of an alternator (active or inactive). To do so, an alternator must be connected to the "DI_Battery_Management_Alternator" interface and be controllable.

The MBAC can read out the voltage of a secondary battery in a range between 2 threshold values in volts and with a specific accuracy. To do so, a secondary battery must be connected to the "AI_Battery_Voltage" interface and be controllable.

The MBAC can read out the current flow difference in a secondary battery in a range between 2 threshold values in amps and with a specific accuracy. To do so, a secondary battery must be connected to the "AI_Current_Flow_Difference" interface and be controllable.
