Zusammenfassung:	To provide a cell cooling system of a vehicle capable of cooling secondary cells efficiently while suppressing power consumption.SOLUTION: A cell cooling system of a vehicle including a battery cooling device 15 powered by electricity supplied from secondary cells for driving the vehicle to cool the secondary cells has a structure cooled by introducing travel wind of the vehicle into a case receiving the secondary cells. The cell cooling system includes a delivery battery temperature prediction unit 38 for predicting the delivery battery temperature of the secondary cells on the basis of a calorific value of the secondary cells estimated by a battery heating amount prediction unit 36, heat release of the secondary cells estimated by a cell heat release prediction unit 37, and the battery temperature detected by a battery temperature sensor 22, and a cell cooling ON/OFF determination unit 39 performing operation control of the battery cooling device on the bases of the delivery battery temperature.SELECTED DRAWING: Figure 2 【課題】電力消費を抑え、効率的に二次電池を冷却することができる車両の電池冷却システムを提供する。【解決手段】車両の走行駆動用の二次電池から供給される電力によって作動して当該二次電池を冷却する電池冷却装置１５を備えた車両の電池冷却システムであって、二次電池を収納するケース内に車両の走行風を導入して冷却される構造となっており、電池冷却システムは、電池発熱量予測部３６により推定されたに二次電池の発熱量と、電池放熱量予測部３７により推定された二次電池の放熱量と、電池温度センサ２２によって検出された電池温度と、に基づいて、二次電池の到達電池温度を推定する到達電池温度予測部３８と、到達電池温度に基づいて電池冷却装置を作動制御する電池冷却ＯＮ/ＯＦＦ判定部３９と、を備えた【選択図】図２
