Beschreibung
Zusammenfassung:	A battery temperature control system includes: a refrigeration cycle including a compressor and a heat exchanger; an accumulator; a condenser; a bypass for supplying refrigerant discharged from the compressor to the heat exchanger while bypassing the condenser; a valve mechanism; a temperature detector; a controller configured to switch the valve mechanism; and an introduction passage branched off from a passage extending from a discharge port of the compressor to a position in the refrigeration cycle upstream of the heat exchanger. The introduction passage supplies the refrigerant reduced in pressure to a part of a passage extending from a position in the refrigeration cycle downstream of the accumulator or downstream of the heat exchanger to a position in the refrigeration cycle upstream of the accumulator. The controller adjusts an opening degree of the variable throttle disposed in the introduction passage depending on a temperature detected by the temperature detector.
