How to have isolated grounds(separate electrical references) for an electric vehicle simulation?

I want to have different electrical references/grounds for the High Voltage and Low Voltage systems in an Electric Vehicle Model so that I can replicate the physical isolation that is followed in a practical Electric Vehicle. Kindly guide me how to introduce the same in my simulation.

Simscape provides a page that contains guidelines for using domain-specific reference blocks (such as Electrical Reference) in Simscape diagrams, along with examples of correct and incorrect configurations.
