A cooling system of a vehicle having a fuel cell stack includes a pump for circulating a coolant in a coolant line passing through the fuel cell stack, a heater disposed on the coolant line for heating the coolant by electric power supplied by a drive motor of the vehicle, and a controller for operating the heater by a surplus electric power generated by the drive motor when a heat generation amount of the fuel cell stack is less than a first threshold value and a rotation speed of the pump is above a second threshold value, and for turning off the heater when the heat generation amount of the fuel cell stack is less than the first threshold value and the rotation speed of the pump is less than the second threshold value.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0097888 filed with the Korean Patent Office on Jul. 9, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to cooling systems and methods of operating the cooling systems, and more particularly, to cooling systems and methods of operating for cooling a fuel cell stack of a vehicle. Background technique [0004] Vehicles are often provided with cooling systems to maintain optimum temperatures of fuel cell stacks, inverters, electric motors, engines and / or other electrical equipment that generate heat during operation. Such a cooling system may be an air-cooled type that cools the heat source by introducing external air to the heat source, or a water-cooled type that circulates a coolant to cool the heat source. Generally, the cooling performance of the a...
