battery charging/discharging controller -凯发k8网页登录

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:
