A battery cooler system has a refrigerating medium circuit (10) having a compressor (12), a gas cooler (14), a pressure reduction device (40) and a battery cooler circuit (30) which has a plurality of cooling branches (34, 36), the pressure reduction device (40) having a brancher (44) and at least a first and a second throttle stage. There is provided between the first and the second throttle stage a branching location (56) with which the refrigerating medium flow is distributed over the cooling branches (34, 36) of the battery cooler circuit (30). The two throttle stages of the pressure reduction device (40) are adjusted in such a manner that the refrigerating medium is present substantially in a single phase downstream of the first throttle stage.
