<p><P>PROBLEM TO BE SOLVED: To switch a cooling air flowing direction for eliminating nonuniformity of the temperature of a battery mounted on an electric motor vehicle, without adding a special part. <P>SOLUTION: A passage for flowing cooling air of the battery 36 is provided with an air filter 68, a front connecting pipe 110, a battery case 37, a rear connecting pipe 69 and a cooling fan 70. Air introduced from the air filter 68 side is exhausted from the cooling fan 70 by flowing in the battery 36 from a first cooling air passage 110 by normally rotating in the rotational direction of the cooling fan 70. The cooling air introduced from a second cooling air passage 69 is exhausted via the first cooling air passage 110 and an air cleaner 68 by flowing in the battery 36 by reversely rotating in the rotational direction of the cooling fan 70. The first cooling air passage 110 becomes the introducing side of the cooling air when the vehicle travels, and the second cooling air passage 69 becomes the introducing side of the cooling air when stopping. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
