<p>This cooling-air exhaust-duct structure for an electric vehicle is provided with a battery exhaust duct (58), a charger exhaust duct (61), and a first-converter exhaust duct (59). One end of the battery exhaust duct (58) is coupled to a cooling-air exhaust port (31e) for a drive battery (31) that is cooled by a cooling fan (52), and the other end of the battery exhaust duct (58) is coupled to a drafter opening (3a) that leads outside the vehicle. The charger exhaust duct (61) is disposed further towards the top of the vehicle than the drive battery (31). One end of the charger exhaust duct (61) is coupled to a cooling-air exhaust port (37b) for a charger (37) that is cooled by a cooling fan (75) that blows less air than the aforementioned cooling fan (52), and the other end of the charger exhaust duct (61) is coupled to a connection opening (58d) formed at a point partway down the battery exhaust duct (58). The first-converter exhaust duct (59) is disposed further towards the top of the vehicle than the charger (37). One end of the first-converter exhaust duct (59) is coupled to a cooling-air exhaust port (35c) for a first DC-to-DC converter (35) that is cooled by a cooling fan (71) that blows less air than the aforementioned cooling fan (75), and the other end of the first-converter exhaust duct (59) is coupled to a first connection opening (61e) formed at a point partway down the charger exhaust duct (61).</p> |
