Description
This SCL function block, FB_BatteryManagement, controls the charging and discharging of a battery while maintaining voltage, current, and temperature limits. It implements automatic safety shutdown in the event of limit violations and allows manual enablement of charging and discharging processes. It can be run directly in the Siemens TIA Portal.

Note: All modules are designed exclusively as a learning and optimization basis and are not approved for live operation. System modules, in particular, must be finally tested and commissioned by qualified personnel before productive use.

How it works

  1. Limit value test: Voltage, current, temperature outside limits → charging and discharging contactors off, alarm on, HMI "ERROR: Shutdown", RETURN
  2. Safe area + charging enable active + U < U_Max → start charging process, HMI “CHARGE”
  3. Safe area + discharge enable active + U > U_Min → start discharge process, HMI “DISCHARGE”
  4. No release → System remains in “READY” state

Technical details
• Inputs: Battery voltage, battery current, battery temperature, U_Min/U_Max, I_Max, Temp_Min/Temp_Max, charge and discharge enable
• Outputs: Charging contactor, discharging contactor, alarm, HMI status text
• Immediate RETURN in case of limit violation
• IF/ELSIF structure for deciding the operating states

Possible applications
• UPS systems and uninterruptible power supplies
• Battery storage in PV systems
• Electric vehicle charging systems
• Training and demonstration projects in energy management

compatibility
• Siemens S7-1200 & S7-1500
• TIA Portal ≥ V13; recommended V16+ for PLCSIM & comprehensive HMI visualization
