Abstract

A thermal management system includes a refrigerant line including a compressor, a water-cooled condenser, and a cooling core for indoor air conditioning connected to the water-cooled condenser such that refrigerant emerging from the water-cooled condenser is introduced into the cooling core for indoor air conditioning, and a battery line including a high-voltage battery heat exchanging module and a heater core for indoor air conditioning. The battery line is connected to the refrigerant line through the water-cooled condenser in a heat exchangeable manner such that the high-voltage battery heat exchanging module and the heater core for indoor air conditioning are connected in parallel to the water-cooled condenser via a first valve to cause cooling water heated while passing through the water-cooled condenser to be selectively introduced into the high-voltage battery heat exchanging module or the heater core for indoor air conditioning.
