Information

This model illustrates use of a battery connected to an DC voltage source and a constant load. The battery is charged every night at 23:00 until it is full. At 14:00, it is discharged until it is empty. This control is implemented using a finite state machine. The charging and discharging power is assumed to be controlled to a constant value of 10,000 Watts.
