A battery unit with an improved intake and exhaustion structure is provided to reduce temperature deviation of a battery and a performance difference of a battery and to increase a lifetime of a battery by maintaining air volume. A battery unit(100) with an improved intake and exhaustion structure comprises a battery holder, an intake hole(130), and an exhaust fan(150). The battery holder surrounds the outer side of a plurality of battery cells. The intake hole is formed by penetrating the upper part of the battery holder along a longitudinal direction and inhales air by forming the length corresponding to the length of the battery holder. The exhaust fan is installed in a longitudinal direction of the battery holder at the lower part of the battery holder and exhausts the air through an exhaust hole(140). |
