[0037] Working principle: When in use, the energy storage battery to be tested is clamped between the two clamping plates 402, and then the energy storage battery to be tested is connected to the terminal 302. Then, by starting the driving motor 705, the left and right screw rods 702 are driven to rotate. The rotation of the left and right screw rods 702 drives the two explosion-proof glasses 6 to move closer and abut in opposite directions, thereby achieving coverage and protection of the test cavity 202. Then, the power supply is started to perform charge and discharge tests on the energy storage battery. During the test, if the energy storage battery explodes, the explosion-proof glass 6 can block the impact of the explosion to avoid accidental injury to the test personnel. In addition, through the bevel structure of the trapezoidal platform 3, the waste generated when the energy storage battery explodes can automatically fall into the interior of the storage box 8 from the discharge channel 301, reducing the later cleaning of the test table, saving time and effort, and improving the detection efficiency. When the energy storage battery explodes, the exhaust fan 9 can be turned on immediately to draw the harmful gas generated by the explosion of the energy storage battery inside the test chamber 202 into the interior of the purification box 10. The harmful gas is filtered and adsorbed in sequence by the glass fiber filter plate 1002 and the activated carbon filter plate 1003, which can adsorb the harmful gas, reduce emission pollution, and reduce harm to the detection personnel.

[0038] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by setting the explosion-proof glass 6, the impact caused by the explosion can be blocked to avoid accidental injury to the test personnel. In addition, through the bevel structure of the trapezoidal platform 3, the waste generated when the energy storage battery explodes can automatically fall into the interior of the storage box 8 from the discharge channel 301, reducing the later cleaning of the surface of the test table 2, saving time and effort, and improving the detection efficiency.
