Test equipment for resistor anomaly detection

The embodiment of the invention discloses a test device for resistance anomaly detection. The test device is used for detecting a battery module of a device to be detected. The test equipment comprises a mainboard and a display screen, and the mainboard is provided with a resistance detection circuit based on temperature measurement and a power supply circuit. The resistance detection circuit judges whether each resistance value is the same according to the temperature of each current sampling resistor in the battery module, and transmits a judgment result to the display screen for displaying; the power supply circuit converts commercial power into power supply voltage to supply power to the resistance detection circuit. The problem that uneven resistance distribution of the current sampling resistor cannot be found in the prior art is solved. 本发明实施例公开了一种电阻异常检测的测试设备，对待测设备的电池模组进行检测；所述测试设备包括一主板和显示屏，所述主板上设有基于温度测量的电阻检测电路和供电电路；所述电阻检测电路根据电池模组中各个电流采样电阻的温度来判断各个阻值是否相同，并将判断结果传输至显示屏显示；所述供电电路将市电转换为供电电压对电阻检测电路供电。解决了现有无法找出
