Abstract

An electric vehicle battery pack includes a battery case (24), a cooling air intake member, a cooling air exhaust member, and a first cooling fan. The cooling air is to be drawn through the cooling air intake member (48) into a cooling passage. The cooling air intake member is disposed between the battery case and a passenger compartment. The cooling air is to be exhausted through the first cooling air exhaust member (49) from the cooling passage. The first cooling air exhaust member includes a first cooling air exhaust passage through which the cooling air from the cooling passage is to flow. The first cooling air exhaust member is disposed between the battery case and the passenger compartment. At least a part of the first cooling air exhaust passage is disposed between the first cooling fan and the passenger compartment.

Description

technical field [0001] The present invention relates to a battery pack for an electric vehicle, comprising: a battery box that accommodates a plurality of batteries and is arranged below a vehicle compartment; and a cooling air intake that sucks cooling air into a cooling passage formed inside the battery box. means; a cooling air discharge member for discharging cooling air from the cooling passage. Background technique [0002] The following structure is known from the following patent document 1: an air intake duct, a battery box, a first exhaust duct, a ventilation fan, and a second exhaust duct are connected in series, and the air sucked from the air intake duct by driving the ventilation fan is known. The air in the vehicle compartment is supplied to the battery box to cool the battery, and the exhaust gas discharged from the battery box is discharged through the first exhaust duct, the ventilation fan, and the second exhaust duct. [0003] prior art literature [00...
