[0022] The effect achieved by the entire embodiment 1 is that, through the arrangement of multiple guide rails 4 and support plates 5, the support plates 5 can be placed in the guide rails 4 according to actual test requirements, so that the battery modules to be tested are placed on each support plate 5 for unified testing. When the test box main body 1 is conducting high and low temperature tests, the two telescopic rods 10 can be used to synchronously operate to drive the two baffles 11 to move, so that the two baffles 11 completely block the air inlet cavity 8 and the air outlet cavity 7.
