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

    【課題】冷却液の導電率の上昇を抑制することができる電池冷却システムを提供する。【解決手段】システム10は、電池を冷却する冷却液12と、冷却液12が流れる電池冷却回路14と、制御部60とを備える。電池冷却回路14は、放熱器用流路26と、放熱器迂回流路28と、第1調整弁34と、第2調整弁36とを有する。制御部60は、冷却液12の導電率σが上昇した場合に、冷却液12の導電率σが上昇する前と比較して、放熱器迂回流路28を流れる冷却液12の流量を増大させ、第1放熱器22を流れる冷却液12の流量を減少させるように、第1調整弁34と第2調整弁36とを制御する。【選択図】図3
