Abstract
The utility model relates to a test-box used in a high-low temperature test of a battery in the technical field of battery testing. The test-box comprises a box body, a safety valve, a fanner and an inlet branch, wherein, the safety valve is arranged on the top of the box body; the fanner is arranged above the back side of the box body; the inlet branch arranged on the box body in a position opposite to the fanner is connected with an admitting port of the box body; and the safety valve and the fanner are controlled in a linkage manner. Once an explosion or a violent chemical reaction occurs inside the box body when the high-low temperature test of the battery is carried out, the safety valve is opened automatically after the internal air-pressure raises to exceed a threshold value, the safety valve immediately controls the fanner and an electromagnetic valve to open, gas inside the box body is discharged via the fanner, fire-retardant gas is transported into the box body through an air inlet pipe at the same time, internal fire-points are led to be isolated from air, and the purpose of rapidly reducing pressure and putting out the fire can be achieved.
