Specifically, the vibration test stand 1 is used to place the component 100 to be tested and to generate vibration to the component 100 to be tested. In this embodiment, the component to be tested 100 is a temperature monitoring component of a new energy vehicle battery, and may have a plurality of thermistors 101, a first connector 102, and the like, where the thermistors 101 are used for acquiring the temperature of the battery, and the first connector 102 is a resistance data acquisition output interface of the thermistors 101. The first connector 102 is connected to the multi-channel thermistor tester 2 through a first four-wire cable 5 with a second connector 51. That is, the first connector 102 and the second connector 51 are fitted to each other. In the present embodiment, the first connector 102 is a female socket, and the second connector 51 is a male socket. The standard thermistor PCB base 3 is electrically connected with the multi-channel thermistor tester 2 and is used for placing the standard thermistor 200 with the same specification as the thermistor to be tested. The multi-channel thermistor tester 2 is commercially available, and can simultaneously measure the resistance values of a plurality of thermistors. The multi-channel thermistor tester 2 is in communication connection with the upper computer 4. The upper computer 4 is usually an industrial computer, can load a special thermistor test program, and compares and analyzes the thermistor data to be tested and the standard thermistor data collected from the multi-path thermistor tester 2, so as to judge whether the thermistor to be tested has the problem of cold joint or crack.
Because the thermistor is very sensitive to temperature, in order to ensure that the test result is accurate, the thermistor cold joint or crack detection system further comprises a temperature tester 6, wherein the temperature tester 6 is used for measuring the ambient temperature and is in communication connection with the upper computer 4, for example, in a wired communication mode such as an RS232 or RS485 serial communication line or in a wireless communication mode such as Bluetooth.
