System and method of pre-loading a two-phase cooling system for electric vehicles

A cooling system for an electric vehicle includes a cooling system loop including a refrigerant, a compressor, and a condenser. The cooling system loop is configured to receive the refrigerant after the refrigerant exits the condenser. The cooling system loop comprises a separator configured to receive liquid refrigerant, and a component located downstream from the separator. A vehicle plug monitor circuit generates a plug monitor signal when the vehicle is coupled to an external power source. A controller operates the compressor in response to the plug monitor signal to communicate liquid refrigerant to the separator.
