I want to make a model that consists of 8 brushless DC motors and 4 battery packs. I would like the model to show me my state of charge, by inputing the torque load on the motor. Any leads or help to solve this issue is much appreciated.
you can use simscape electrical to do this. This example has a BLDC with speed control implemented. You can easily duplicate this to have multiple BLDCs, and then decide how to connect them to a battery (replace the dc source with a battery model).
