PROBLEM TO BE SOLVED: To provide a vehicular heat pump system for improving heating efficiency by using a waste heat source.SOLUTION: A vehicular heat pump system includes: a battery cooling line 101 coupled to a battery module B and having cooling water flowing therein; a chiller 110 coupled to the battery cooling line via a first connection line 111 to control a temperature of the cooling water by selectively exchanging heat between a refrigerant flowing into the inner side and the cooling water and coupled to a refrigerant line of air conditioning means having the refrigerant flowing therein via a second connection line 113; electrical cooling means 10 that includes a radiator 12 and a first water pump 14 coupled to each other via a cooling line so that the cooling water circulates to cool a motor and an electrical component and that is selectively coupled to the battery cooling line and the first connection line via a first valve; and a solenoid type expansion valve 39 provided in the second connection line between the refrigerant line and the chiller.SELECTED DRAWING: Figure 1
