It has a large test compartment. The existing high and low temperature test chamber requires two different devices for cooling and heating to work separately, which has high configuration costs and occupies a large space.

[0003] According to the authorization publication number CN212348760U, a high and low temperature test box for electric vehicles is disclosed. The device is moved to a suitable position by a roller 14, and then the handle 6 is held to open the box door 5, and the plug board 9 is inserted into a groove of a suitable height opened inside the inner surface of the box body 1, and the internal space distribution is adjusted. The device to be tested is placed on the storage plate 16, and the box door 5 is closed. The power cord 2 is connected to an external power supply. Through the control panel, the heater 11 or the low-temperature gas refrigerator 12 is turned on or off to increase or decrease the internal temperature of the device. The internal temperature monitor 8 transmits the temperature data to the data display screen 4. According to the data on the data display screen 4, the temperature monitor 8 and the low-temperature gas refrigerator 12 can be controlled by the control panel 3 to accurately adjust the temperature inside the device. After the test is completed, the box door 5 is opened, the device to be tested is taken out, the box door 5 is closed, and finally the power cord 2 and the external power supply are disconnected.
