The model presents Battery charging/discharging Control implemented in a case study that involves a DC bus (with a constant voltage), battery, a common load, and a bidirectional two-switch Buck-Boost DC-DC converter.

The control of battery charging and discharging is based on two PI controllers:
1- one is for reference current generation (dependant on mode of operation: charging or discharging)
2- the other is for Current control of battery.

The presented case study includes two modes of operation:
1-Charging mode: automatically activated when DC bus is connected and the control objective i.e: set point (of the 1st PI closed loop) becomes the full voltage of battery.
2-Discharding mode: automatically activated when DC bus is NOT connected and the control objective (of the 1st PI closed loop) becomes load voltage in order the maintain a constant load voltage during discharging.

The following video (which you can check for more details) inspired me to develop this model:
