To provide a smoke exhaust structure for a battery pack in which the interior of a vehicle is prevented from being filled with smoke exhaust gas including toxic components, thereby preventing adverse effects on occupants.SOLUTION: A smoke exhaust structure 11 for a battery pack has a first smoke exhaust path 31 using smoke exhaust ducts 22 capable of being connected to battery cells and a second smoke exhaust path 32 using a cooling air path of an inverter. In the smoke exhaust structure 11 for the battery pack, when an exhaust gas is generated from a battery cell in an abnormal event of a battery module 21, the smoke exhaust gas is discharged out of a vehicle 12 using the first and second smoke exhaust paths 31, 32. This structure prevents the interior of the vehicle 12 from being filled with the exhaust gas including toxic components, thereby preventing adverse effects on occupants.SELECTED DRAWING: Figure 3

    【課題】車両の車室内が有毒成分を含む排煙ガスにより充満することが防止され、乗員へ悪影響を及ぼすことが防止される電池パックの排煙構造を提供する。【解決手段】本発明の電池パックの排煙構造11は、電池セルと連通可能な排煙ダクト22を用いた第1の排煙経路31と、インバータの冷却風路を用いた第2の排煙経路32と、を有する。そして、電池パックの排煙構造11では、電池モジュール21の異常時に電池セルから排煙ガスが発生した場合には、第1及び第2の排煙経路31,32を用いて、上記排煙ガスが車両12の車室外へと排出される。この構造により、車両12の車室内が、有毒成分を含む排煙ガスにより充満されることが防止され、乗員へ悪影響を及ぼすことが防止される。【選択図】図3
