a power supply configured to supply power to the charger;
a frame including:
a first installation space in which the power supply is located;
a second installation space in which the charger is located;
a frame passage located between the first installation space and the second installation space, the frame passage including:
a first partition wall partitioning the frame passage from the first installation space, the first partition wall having a first flow hole; and
a second partition wall partitioning the frame passage from the second installation space, the second partition wall having a second flow hole;
a cooling duct located in the frame passage, the cooling duct having a supply hole open to the frame passage;
at least one duct air supply configured to supply cooling air to the cooling duct;
a first blowing fan configured to introduce air in the frame passage into the first installation space through the first flow hole; and
a second blowing fan configured to introduce air in the second installation space into the frame passage through the second flow hole.
2. The charge-and-discharge test apparatus according to claim 1 , wherein the frame has a first discharge hole configured to discharge air in the first installation space outside the frame, and
wherein the cooling air introduced into the frame passage through the cooling duct is introduced into the first installation space, and then discharged to the outside of the frame through the first discharge hole.
3. The charge-and-discharge test apparatus according to claim 2 , wherein the air introduced into the frame passage from the second installation space through the second flow hole is introduced into the first installation space together with the cooling air supplied from the cooling duct, and then discharged to the outside of the frame through the first discharge hole.
4. The charge-and-discharge test apparatus according to claim 2 , wherein the first discharge hole is located to face the first flow hole.
5. The charge-and-discharge test apparatus according to claim 4 , wherein the power supply is located between the first discharge hole and the first flow hole.
6. The charge-and-discharge test apparatus according to claim 2 , further comprising a power supply room surrounding the frame, the power supply room including:
a room air supply; and
a room exhaust.
7. The charge-and-discharge test apparatus according to claim 6 , wherein the power supply room is configured such that air introduced into the power supply room through the room air supply is introduced into the second installation space of the frame.
8. The charge-and-discharge test apparatus according to claim 7 , wherein the power supply room is configured such that air discharged into the power supply room through the first discharge hole of the frame is discharged to outside of the power supply room by the room exhaust of the power supply room.
9. The charge-and-discharge test apparatus according to claim 1 , wherein the at least one duct air supply includes:
a first duct air supply connected to a first end of the cooling duct; and
a second duct air supply connected to a second end of the cooling duct,
wherein the first duct air supply includes:
a first air supply duct connected to the cooling duct; and
a first air supply fan located in the first air supply duct, and
wherein the second duct air supply includes:
a second air supply duct connected to the cooling duct; and
a second air supply fan located in the second air supply duct.
10. The charge-and-discharge test apparatus according to claim 1 , wherein the first flow hole and the second flow hole are located at different heights relative to a bottom of the frame in the frame.
11. The charge-and-discharge test apparatus according to claim 1 , wherein the supply hole of the cooling duct is located at a higher position than the first flow hole in the frame.
12. The charge-and-discharge test apparatus according to claim 1 , further comprising a controller configured to control the power supply, the charger, the duct air supply, the first blowing fan, and the second blowing fan,
wherein, when the power is supplied to the charger, the controller operates the duct air supply to supply the cooling air to the cooling duct, and operates the first blowing fan and the second blowing fan.
13. A control method of the charge-and-discharge test apparatus according to claim 1 , wherein the control method of the charge-and-discharge test apparatus comprises:
applying power to the charger;
supplying cooling air to the cooling duct;
operating the first blowing fan to supply cooling air in the frame passage into the first installation space; and
operating the second blowing fan to discharge the air in the second installation space to the frame passage.
