PROBLEM TO BE SOLVED: To provide a cooling device for a battery pack that can suppress cool air or hot air in a space above a package tray from discomforting crew members.SOLUTION: A cooling device for a battery pack comprises cooling means 14a, 15, 16 for cooling a battery pack 11 with air sucked from a passenger compartment 2, exhausting the air to a cargo chamber 2 and returning the exhaust air through an intercommunication part 5a of a package tray 5 into the passenger compartment 2, and suction and exhaust means 20 for sucking air above the package tray 5 from an air suction port 21a adjacent to the intercommunication part 5a of the package tray 5, and exhausting the air from an exhaust port 22a into the passenger compartment 2. When the temperature of air above the package tray 5 is estimated or measured to be higher than a first predetermined temperature TH or lower than a second predetermined temperature TL lower than the first predetermined temperature TH, the suction and exhaust means 20 is operated to suck the air above the package tray 5 from the air suction port 21a adjacent to the intercommunication part 5a of the package tray 5 and exhaust the air from the exhaust port 22a into the passenger compartment 2.SELECTED DRAWING: Figure 1

    【課題】パッケージトレイの上方空間における冷気または熱気が乗員に不快感を与えることを抑制する電池パックの冷却装置を提供することである。【解決手段】車室2から吸引した空気により電池パック11を冷却して荷室2に排気し、当該排気をパッケージトレイ5の連通部5aを通して車室2に戻す冷却手段14a,15,16と、パッケージトレイ5の連通部5aに隣接する吸気口21aからパッケージトレイ5の上方の空気を吸引して排気口22aから車室2に排気する吸排気手段20と、を備え、パッケージトレイ5の上方の空気温度が、第1の所定温度THより高い、または第1の所定温度THより低い第2の所定温度TLより低いと推定または測定されるときに、吸排気手段20を動作させて、パッケージトレイ5の上方の空気を、パッケージトレイ5の連通部5aに隣接する吸気口21aから吸引して排気口22aから車室2に排気する。【選択図】図1
