A battery system includes: a battery and a battery management system (BMS) for controlling charging of the battery depending on a normal mode using a first battery capacity between a first lower limit state of charge (SOC) and a first upper limit SOC or an eco-friendly mode using a second battery capacity between a second lower limit SOC and a second upper limit SOC, the first lower limit SOC is smaller than the second lower limit SOC, and the first upper limit SOC is greater than the second upper limit SOC.

A heat pump system for a vehicle having a complex valve device including a three-way valve, an on-off valve, expansion means and connection blocks are formed integrally with one another, the three-way valve part being connected to the refrigerant circulation line of an inlet of the exterior heat exchanger such that the refrigerant selectively bypasses the exterior heat exchanger, the on-off valve part being connected to an inlet of the bypass line to open and close the bypass line. Connection blocks connect the three-way valve part and the on-off valve part with the refrigerant circulation line of an outlet of the exterior heat exchanger to communicate with each other. Expansion means are connected to an inlet of the three-way valve part to selectively expand refrigerant discharged from an interior heat exchanger. All functions of the heat pump system are thus conducted through a refrigerant control of the complex valve device.
