Zusammenfassung:	To provide a battery temperature management device for managing the temperature of a nickel-metal hydride battery mounted on a vehicle, and capable of suppressing a rise in battery temperature while preventing unnecessary discharge after travel completion.SOLUTION: A BCU13 configuring a battery temperature management device 1 is provided with: a discharge-necessity determination section 132 for determining whether or not discharging after travel completion is necessary on the basis of whether or not an index value that correlates with temperature rise of a battery pack 11 after travel completion (for example, charge/discharge amperage of the battery pack 11 immediately before travel completion, etc.) is a predetermined threshold value or more; and a discharge control section 133 for driving a discharge circuit 40 to discharge when discharging is determined to be necessary.SELECTED DRAWING: Figure 1 【課題】車両に搭載される、ニッケル水素電池（バッテリ）の温度を管理するバッテリ温度管理装置であって、走行終了後に、不必要な放電を防止しつつ、バッテリ温度が上昇することを抑制することが可能なバッテリ温度管理装置を提供する。【解決手段】バッテリ温度管理装置１を構成するＢＣＵ１３は、走行終了後の組電池１１の温度上昇と相関を有する指標値（例えば、走行終了直前の組電池１１の充放電電流量等）が所定のしきい値以上であるか否かに基づいて、走行終了後に放電する必要があるか否かを判断する放電要否判断部１３２と、放電が必要であると判断された場合に、放電回路４０を駆動して放電を行う放電制御部１３３とを備えている。【選択図】図１
