Abstract
A coolant system includes a battery coolant line fluidly connected to a battery, a power electronics coolant line fluidly connected to a power electronic component, a radiator coolant line fluidly connected to a radiator, a control valve configured to allow the battery coolant line, the power electronics coolant line, and the radiator coolant line to be fluidly connected to or separated from each other, a temperature sensor disposed in at least one of the battery coolant line, the power electronics coolant line, or the radiator coolant line, and a controller configured to control a switching operation of the control valve under a predetermined condition in a manner that fluidly connects a coolant line without any temperature sensor to a coolant line with the temperature sensor, and determine a temperature of a coolant passing through the coolant line without any temperature sensor based on a temperature sensed by the temperature sensor.
