    C- AND S-OPERATION MANUAL - EN Figure 10. A simplified example of democratic power management. On a simple case - at the beginning as all EVs are charging on outputs 1-4, each EV receives 25% of the cabinet’s charging power. When the EVs on outputs 2 and 4 end charging, remaining charging power 50% is available and is routed to EVs on outputs 1 and 3 (both receives +25%).

On a simple case - at the beginning as the first EV starts to charge at 75% (150 kW), when the next EV starts to charge at output 3 it receives 25% (50 kW). As the third driver starts to charge on output 2 the first arrived still receives 75% and second and third receive only 12.5% (25 kW each).
