Vehicle thermal management system and method for controlling the same

Abstract

A vehicle thermal management system, includes: a refrigerant subsystem including a refrigerant circulation path; a first coolant subsystem including a first coolant circulation path and a PE component fluidly connected to the first coolant circulation path; a second coolant subsystem including a second coolant circulation path and a radiator and a pump fluidly connected to the second coolant circulation path; a heat exchanger including a refrigerant passage fluidly connected to the refrigerant circulation path, a first coolant passage fluidly connected to the first coolant circulation path, and a second coolant passage fluidly connected to the second coolant circulation path; and a controller configured for controlling the pump of the second coolant subsystem based on a temperature of a refrigerant flowing into the refrigerant passage of the heat exchanger and a temperature of a second coolant flowing into the second coolant passage of the heat exchanger.
