Air distribution device for battery cell cooling test and test method

The invention discloses an air distribution device for a battery cell cooling test and a test method, and relates to the technical field of electrochemical energy storage systems. The air distribution device for the cell cooling test comprises a semicircular first track, a semicircular second track, a semicircular moving unit and a semicircular air outlet unit, the second track is coaxially arranged on the arc-shaped inner side of the first track and is adjustable in height, and the moving unit is slidably arranged on the second track. And the air outlet unit is rotationally connected with the moving unit, an air outlet is formed in one end, deviating from the moving unit, of the air outlet unit, and the air outlet unit is used for generating air flow with uniform speed distribution at the air outlet and aligning to the battery cell located on the axis of the first track. The air distribution device for the battery cell cooling test is simplified, uniform and continuous battery cell cooling airflow can be pro
