@ Sankeerth Sudhan as requested:
You can control your load by using a switch ( power electronics block)connected between two loads ( 1kW and 4kW).
As for battery SOC, there are several techniques to charge such as: Constant current , Constant voltage + Constant current
Maybe you can do a review on the techniques available for battery charging.
The simplest way is to use a constant current to charge the battery.
You can use a matlab function block to create the controller. The input of the block is the battery voltage and current. Inside the block, you may need to write a matlab script that reads the values and determine when to charge and discharge the battery. The function block output should be connected to a PID controller which will make sure it will deliver constant current to charge the battery. After the voltage is max, the controller will send a signal to a switch that will disconnect the battery from the source.
If you want to ask a different question, please open a new thread.
thanks.. hope this helps
