To provide a battery cooling system capable of suppressing a rise in conductivity of cooling liquid.SOLUTION: A system 10 comprises: cooling liquid 12 for cooling a battery; a battery cooling circuit 14 through which the cooling liquid 12 flows; and a control part 60. The battery cooling circuit 14 has a radiator flow path 26, a radiator bypass flow path 28, a first regulating valve 34, and a second regulating valve 36. When conductivity σ of the cooling liquid 12 rises, the control part 60 controls the first regulating valve 34 and the second regulating valve 36 in such a manner as to increase a flow rate of the cooling liquid 12 flowing through the radiator bypass flow path 28 and decrease the flow rate of the cooling liquid 12 flowing through the first radiator 22, as compared with the flow rate before the rise of the conductivity σ of the cooling liquid 12.SELECTED DRAWING: Figure 3
