1. A thermal management system for a vehicle, the thermal management system comprising:
a cooling apparatus configured to circulate a coolant through a coolant line and cool at least one electrical component, the cooling apparatus including a first radiator, a first water pump, and an oil cooler configured to cool at least one motor, wherein the coolant line is configured to connect the first radiator to the first water pump;
a battery cooling apparatus configured to circulate the coolant to a battery module, and including a second radiator, a second water pump and the battery module connected to each other by a battery coolant line;
a chiller provided in the battery coolant line connected to a refrigerant line of an air conditioner through a refrigerant connection line, and configured to allow the coolant to pass through an interior of the chiller and adjust a coolant temperature by heat-exchanging a selectively received coolant with a refrigerant supplied from the air conditioner;
a heater provided in the coolant line between the at least one electrical component and the first radiator, and configured to heat a vehicle interior by using the coolant supplied from the cooling apparatus; and
a first branch line provided in the coolant line between the first radiator and the first water pump, and connected to the coolant line between the oil cooler and the first radiator through a first valve
wherein the air conditioner includes a condenser that is connected to the coolant line and is configured to pass the coolant circulating through the cooling apparatus.
