Abstract: A battery case of a battery storage device is disposed on a vehicle floor, thereby securing an interior space. A battery module of the battery storage device can be cooled by using an interior air, thereby simplifying a cooling structure and saving a manufacturing cost. In addition, the battery storage device for an electric vehicle blocks noise generated by a cooling device and an electrical component from flowing into the interior, thereby preventing the occurrence of a passenger's discomfort feeling caused by the noise.
