We can run EV model in Simulink using FMUs for the motor and battery without needing the Simscape toolbox. Just treat the FMUs like normal Simulink blocks. Use the FMU Import block to bring in your motor and battery FMUs, and connect them with regular signal lines. For example, if the motor FMU gives the current demand, we can send that as input to the battery FMU. The battery FMU then gives you the output voltage, which we can also send back to the motor FMU if needed. This way, we create a working loop without using any electrical components from Simscape.
To mimic the behavior of an electric circuit (which Simscape would normally handle), we can use basic Simulink blocks like Gain, Sum, Integrator, and Unit Delay to create the control or feedback logic. Also, make sure the battery’s negative terminal is tied to a reference, like a constant zero block, so the voltage is defined properly. This method keeps everything within standard Simulink and supports co-simulation by simply passing signals between the FMUs. Just be sure the solver settings and sample times are set up correctly so everything stays in sync during simulation.
