PROBLEM TO BE SOLVED: To provide a control device of a vehicle air conditioner system, configured to achieve temperature management so as not to interfere with charging/discharging a battery, and to satisfy output request for a vehicle indoor air conditioner.SOLUTION: A vehicle air-conditioner system 1 includes: a vehicle indoor air conditioner unit 30; a battery cooling unit 20 cooling an in-vehicle battery for operation formed of a plurality of battery cells; a refrigerant circulation circuit 40 supplying refrigerant to the vehicle indoor air conditioner unit 30 and the battery cooling unit 20. A control device for the vehicle air-conditioner system 1 includes: a solenoid valve 34 disposed in the refrigerant circulation circuit 40 to cut off the refrigerant to be supplied to vehicle indoor air conditioner unit 30; a temperature detection means 12 detecting each battery temperature of a plurality of battery cells; and a control means 50 setting a representative battery temperature based on each battery temperature detected by the temperature detecting means 12, and controlling the solenoid valve 34 based on the representative battery temperature.
