To provide a blower device for battery capable of determining presence/absence of abnormality in air blowing performance quickly with high accuracy.SOLUTION: A blower device 1 includes: a blower duct 4 for passing cooling air C to a battery; a blower 5 provided in the middle of the blower duct 4; a dust collecting filter 6 provided at a position further on the upstream than the blower 5 in the blower duct 4; and a performance detection part 7 for detecting deterioration in air blowing performance of the blower duct 4. A sound collector 8 is arranged at the position further on the upstream than the dust collecting filter 6 in a circulation path of the cooling air C. The performance detection part 7 includes an operation time determination part 11 which compares operation time sound measurement information acquired from the sound collector 8 during the operation of the blower 5 with standard blower noise data during the operation of the blower 5, and, in the case where the operation time sound measurement information is deviated from the standard blower noise data by a degree equal to or greater than a predetermined degree, which determines that there is deterioration in air blowing performance.SELECTED DRAWING: Figure 1
【課題】高い精度で迅速に送風性能の異常の有無を判定できる電池の送風装置を提供すること。【解決手段】本開示技術では、電池への冷却風Cを通す送風ダクト4と、送風ダクト4の途中に設けられた送風機5と、送風ダクト4における送風機5より上流の位置に設けられた集塵フィルタ6と、送風ダクト4の送風性能の低下を検知する性能検知部7とを有する電池の送風装置1において、冷却風Cの流通経路における集塵フィルタ6より上流の位置に集音器8を配置し、性能検知部7は、送風機5の稼働中に集音器8から取得した稼働時測音情報を、送風機5の稼働中における標準送風機騒音データと対比し、稼働時測音情報が標準送風機騒音データからあらかじめ定めた程度以上に乖離している場合に送風性能の低下があると判定する稼働時判定部11を有することとした。【選択図】図1
