Abstract
In a battery pack having an improved cooling structure, unit cells, an internal cooling fan and a drive motor are arranged in an inside space of a housing. The inside space of the housing is completely sealed. The drive motor drives the internal cooling fan to supply cooling air. The cooling air circulates in the inside space of the housing to cool the unit cells. Radiation fins are formed on at least one specific exterior surface of the housing. The specific exterior surface has a superior radiation capability which is higher than that of each of the other exterior surfaces of the housing. The cooling air is supplied in turn surfaces of the unit cells and interior surface of the housing corresponding to the exterior surface on which the radiation fins are formed.
