NOVELTY - The electric vehicle battery pack (31) has a first cooling air exhaust duct (49) which is disposed between a battery case and a passenger compartment. A first cooling fan (47) is arranged to exhaust the cooling air from a first cooling air exhaust passage to outside of the first cooling air exhaust duct (48). A section of the first cooling exhaust passage is disposed between the first cooling fan and the passenger compartment. A support frame is provided on the battery case to support the first cooling air exhaust duct and the first cooling fan.    USE - Battery pack for electric vehicle.    ADVANTAGE - Reduces the size of the cooling apparatus since the exhaust ducts and the cooling fans are fastened together to the support frame using the shared bolts. Reduces the number of components since the need for sealing unit in the connection section is eliminated. Prevents foreign materials, e.g., dirt and water, from being drawn through the cooling air intake port since the battery case can block the dirt or water. Improves cooling of the battery by driving the ventilation fan and supplying the air in the passenger compartment drawn through the air intake duct to the battery case. Noise and vibration generated by the cooling fan is negligibly transferred to the passenger compartment since at least part of the cooling air exhaust passage of the cooling air exhaust member is disposed between the cooling fan and the passenger compartment, thus noise and vibration generated by the cooling fan can be blocked by the cooling air exhaust passage. Even when water enters the battery case through the cooling fan that is stopped, intrusion of the water into the cooling passage is effectively prevented, since the cooling air exhaust passage is located above the cooling fan.
