1. A thermal management system for a vehicle comprising:
a cooling apparatus including a radiator, a first water pump, and a valve connected through a coolant line, the cooling apparatus configured to circulate a coolant in the coolant line to cool at least one electrical component provided in the coolant line;
a battery cooling apparatus including a battery coolant line connected to the valve, a second radiator, a second water pump, and a battery module connected through the battery coolant line to circulate the coolant in the battery module;
a chiller connected to a first connection line, connected to the battery coolant line between the second radiator and the battery module, and a second connection line connected to the valve, and connected to a refrigerant line of an air conditioner through a refrigerant connection line, the chiller being configured to adjust a temperature of the coolant by performing heat exchange between the coolant that is introduced in the cooler and a refrigerant that is selectively supplied from the air conditioner;
a heater provided in the coolant line between the electrical component and the first radiator to heat a vehicle interior by using a coolant supplied from the cooling apparatus;
a branch line having a first end connected to the coolant line between the first radiator and the heater, and a second end connected to the second connection line between the valve and the chiller; and
a condenser included in the air conditioner and connected to the coolant line so as to pass the coolant circulating through the cooling apparatus.
