To provide a battery abnormality detection system, capable of detecting a battery abnormality during parking.SOLUTION: A control unit 35 includes: a selection section 39 which selects one assumed adaptation coefficient α1 among a plurality of assumed adaptation coefficients α1 stored in a storage section 37, on the basis of temperature Tx0 measured by a first temperature detection device 31 and outside air temperature Ty0 measured by a second temperature detection device 32; a calculation section 41 which calculates an actually measured adaptation coefficient α2, on the basis of the temperature Tx0 and temperature Tx1 measured by the first temperature detection device 31 and outer air temperature Ty1 measured by the second temperature detection device 32; and a determination section 43 which determines that a battery is abnormal when the assumed adaptation coefficient α1 selected by the selection section 39 is more than the actually measured adaptation coefficient α2, and determines that a battery is normal when the assumed adaptation coefficient α1 is equal to or less than the actually measured adaptation coefficient α2.SELECTED DRAWING: Figure 1
【課題】駐車中において電池の異常を検出することができる電池異常検出システムを提供する。【解決手段】制御装置３５は、第１温度検出装置３１によって測定された温度Ｔｘ０と、第２温度検出装置３２によって測定された外気温Ｔｙ０とに基づいて、記憶部３７に記憶された複数の想定適合係数α１から１つの想定適合係数α１を選択する選択部３９と、第１温度検出装置３１によって測定された温度Ｔｘ０および温度Ｔｘ１と、第２温度検出装置３２によって測定された外気温Ｔｙ１とに基づいて、実測適合係数α２を算出する算出部４１と、選択部３９によって選択された想定適合係数α１が実測適合係数α２より大きい場合には異常と判定し、想定適合係数α１が実測適合係数α２以下の場合には正常と判定する判定部４３と、を備えている。【選択図】図１
