Abstract

An electric vehicle battery pack includes a battery case (24), a cooling air intake member (48), a first cooling air exhaust member (49), a second cooling air exhaust member, and a first cooling fan. The battery case is disposed under a passenger compartment of an electric vehicle to contain a plurality of batteries. The first cooling air exhaust member is disposed to overlap at least a part of the cooling air intake member when viewed from a width direction of the electric vehicle. The second cooling air exhaust member is disposed to overlap at least a part of the cooling air intake member when viewed from the width direction. The first and second cooling air exhaust members are respectively disposed on both sides of the cooling air intake member in the width direction.

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. a cooling air discharge member that discharges cooling air from the cooling passage; and a cooling fan that discharges the cooling air sucked from the cooling air suction member through the cooling passage from the cooling air discharge member. 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 f...
