i am beginner to use matlab and simulink and i tried to build my first project of electric vehicle in simulink. so i took the operators from the library without altering any values to run basic operations of electric vehicle. but i get this error shown in below picture:

You have blocks that have a voltage source, but which you do not supply a definite voltage for. Either you left the input unconnected or else you have a chain that does not supply a definite voltage for them.
It might possibly be the case that the input voltage is given a specific voltage through a feedback loop that is not properly connected.

Hello Nimil,
In order to solve the issue, you have to add “Electrical Reference” block from the Simscape Library as there are controlled current source and voltage source blocks which needs to be connected to the electrical domain reference block. You can find the block at Simscape >> Electrical >> Connectors&References >> Electrical Reference.
You can refer to the documentation provided below for further information
Thank you.
