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
