A battery pack comprises a battery housing pack which sets an inner area having first and second inner spaces and a middle space. The battery pack housing comprises an inlet and an outlet which communicate with the first and second inner spaces, respectively. The battery pack has a battery module positioned in the first inner space, and the battery module has a first battery cell and a heat exchanger. The heat exchanger sets a first flow path part passing therethrough. The battery pack has a fan assembly positioned in the middle space, and the fan assembly has a first electric fan and a heat conductive housing which is positioned in the second inner space and sets a second flow path part. The first electric fan makes air flow through the inlet, the first flow path part, a part of the first electric fan, the second flow path part, and the outlet. |
