To control temperature of a battery at the time of losing an external power source.SOLUTION: A temperature control system 70 in an aircraft 100 flying using electric power generated by an engine 44 or electric power charged in a battery 32 comprises: a battery which starts an engine and store electric power for flight; a temperature adjustment device 71 which heats or cools the battery through at least the electric power charged in the battery and electric power supply from an external power source 111; and a control part 91 which detects whether the electric power supply from the external power source exists or not to control the temperature adjustment device to heat or cool, when the electric power supply from the external power source exists, the battery using the electric power supply from the external power source, or to control the temperature adjustment device to heat or cool, when the electric power supply from the external power source does not exist, the battery using the electric power charged in the battery. Even in a case that the electric power supply from the external power source is lost, temperature of the battery and charged state thereof available for starting the engine and flight can be kept.SELECTED DRAWING: Figure 4 【課題】外部電源を喪失した場合においてバッテリの温度を制御する。【解決手段】温度制御システム７０は、エンジン４４により発電される電力又はバッテリ３２に充電された電力を利用して飛行する航空機１００において、エンジンを始動するとともに飛行するための電力を蓄えるバッテリ、少なくともバッテリに充電された電力及び外部電源１１１からの給電のそれぞれによりバッテリを加温又は冷却する温調装置７１、外部電源からの給電の有無を検出し、外部電源からの給電がある場合に、温調装置を制御して、外部電源からの給電を用いてバッテリを加温又は冷却し、外部電源からの給電がない場合に、温調装置を制御して、バッテリの充電を用いてバッテリを加温又は冷却する制御部９１を備える。外部電源からの給電を喪失した場合においても、エンジン始動可能且つ飛行可能なバッテリの温度及び充電状態を維持することができる。【選択図】図４
