To provide a battery temperature adjustment system of an industrial vehicle that can be charged with electric power at preset charge timing and can surely avoid a function from being restricted at a charging time.SOLUTION: A battery temperature adjustment system of an industrial vehicle comprises: a battery mounted on a vehicle body; a battery controller that controls charge/discharge of the battery; a battery temperature adjustment device that performs an adjustment of temperatures of the battery; and a temperature controller that controls the battery temperature adjustment device on the basis of the temperatures of the battery. In the battery controller, a function restriction temperature Th for restricting a function of the battery and a pre-charging target temperature Tu lower than a target temperature Tt for the battery at which a discharge state becomes optimal are set. The battery controller obtains next charging timing tc during discharge of the battery. The temperature controller controls the battery temperature adjustment device so that the temperature of the battery is equal to the pre-charging target temperature Tu for a period of time from pre-charging timing tb earlier by a predetermined time than the charging timing tc to the charging timing tc.SELECTED DRAWING: Figure 4

    【課題】予め設定された充電タイミングで充電を可能とするとともに充電時に機能制限を確実に回避することができる産業車両のバッテリ温度調節システムの提供にある。【解決手段】車体に搭載されたバッテリと、バッテリの充放電を制御するバッテリコントローラと、バッテリの温度調節を行うバッテリ温度調節装置と、バッテリの温度に基づいてバッテリ温度調節装置を制御する温調コントローラと、を備え、バッテリコントローラには、バッテリの機能を制限する機能制限温度Thと、最適の放電状態となる前記バッテリの目標温度Ttより低い充電前目標温度Tuと、が設定され、バッテリコントローラは、バッテリの放電中に次回の充電タイミングtcを取得し、温調コントローラは、充電タイミングtcの所定時間前の充電前タイミングtbから充電タイミングtcにかけてバッテリの温度が充電前目標温度Tuになるようにバッテリ温度調節装置を制御する。【選択図】 図4
