The cover is provided with a first exhaust port and a second exhaust port. A first exhaust member having a first exhaust passage through which air discharged from the first exhaust port flows is connected to the first exhaust port. A second exhaust member having a second exhaust passage through which air discharged from the second exhaust port flows is connected to the second exhaust port. The first exhaust port is provided so as to overlap at least a part of the electric device when viewed from an opening direction and has a larger opening area than the second exhaust port. A minimum cross-sectional area of the first exhaust passage is smaller than a minimum cross-sectional area of the second exhaust passage. ## Claims ### Claim 1 A power supply device comprising: a battery; an electric device arranged side by side with the battery; a case which accommodates the battery and the electric device and has a case opening; and a cover which covers the case opening, wherein: a cable connected to another electric device arranged outside the case is connected to the electric device; the cover is provided with a first exhaust port and a second exhaust port separated from each other; a first exhaust member having a first exhaust passage through which air discharged from the first exhaust port flows is connected to the first exhaust port; a second exhaust member having a second exhaust passage through which air discharged from the second exhaust port flows is connected to the second exhaust port; the first exhaust port is provided so as to overlap at least a part of the electric device when viewed from an opening direction of the first exhaust port and has a larger opening area than the second exhaust port; and a minimum cross-sectional area of the first exhaust passage is smaller than a minimum cross-sectional area of the second exhaust passage. ### Claim 2 (depends on 1) The power supply device according to claim 1, wherein the cable is inserted into the case through the first exhaust port and connected to the electric device. ### Claim 3 (depends on 1) The power supply device according to claim 1, wherein: the electric device has a fastening portion to which a terminal portion of the cable is fastened; and the fastening portion is provided at a position inside the first exhaust port when viewed from the opening direction of the first exhaust port. ### Claim 4 (depends on 1) The power supply device according to claim 1, wherein: the cover is provided with an intake port for taking in air inside the case, and the first exhaust port is formed on one side of the intake port in a longitudinal direction of the case and the second exhaust port is formed on the other side of the intake port. ### Claim 5 (depends on 4) The power supply device according to claim 4, further comprising: an intake side covering portion which is arranged inside the case and covers a surface of the battery on the intake port side; an exhaust side covering portion which is arranged inside the case and covers a side opposite to the intake side covering portion in a state of interposing the battery; and a fan which is connected to the exhaust side covering portion inside the case, takes in air which is taken in from the intake port and cools the battery, and discharges the air to a side of the exhaust side covering portion where the battery is not arranged, wherein the electric device is arranged side by side on one side of the battery in the longitudinal direction and the fan is arranged on an end portion on the other side of the battery. ### Claim 6 (depends on 5) The power supply device according to claim 5, wherein: the intake side covering portion has an intake portion which takes in air from the intake port to the battery; and the intake portion is located on one end side of the battery in the longitudinal direction and the fan is located on the other end side of the battery.
