This application relates to a short-circuit detection device for battery cells in a winding machine, belonging to the field of battery cell detection technology. To solve the problem of short-circuited battery cells occupying processing time, it includes a detection mechanism arranged on one side of the cold pressing plate of the winding machine. The detection mechanism includes a support frame, a transverse carrier plate, a lifting drive cylinder, a detection plate body, and a detection probe assembly. The support frame is arranged on one side of the cold pressing plate, the transverse carrier plate is arranged on the support frame, the lifting drive cylinder is vertically connected to the transverse carrier plate, and the piston end of the lifting drive cylinder is connected to the detection plate body. The detection probe assembly includes positive electrode detection probes and negative electrode detection probes, which are distributed on the end face of the detection plate body. The support frame is provided with a transverse movement mechanism for driving the transverse carrier plate. This application effectively ensures that short-circuited battery cells are effectively identified and rejected before hot pressing, preventing short-circuited battery cells from occupying hot pressing equipment time and significantly improving production efficiency.

This invention belongs to the field of control technology, specifically relating to a method and system for thermal management control of LED vehicle lights based on multi-source data. The method includes the following steps: acquiring the ambient temperature, vehicle speed, drive current, and drive voltage during LED vehicle light operation; calculating the actual heat generation power of the LED based on the drive current, drive voltage, and non-heating light conversion efficiency constant; using an extended Kalman filter algorithm to fuse the ambient temperature, vehicle speed, drive current, and drive voltage to obtain a filtered and noise-reduced estimated value of the LED junction temperature; calculating the system's comprehensive thermal resistance representing the current heat dissipation condition using the estimated LED junction temperature, ambient temperature, and actual LED heat generation power; and subtracting a preset target LED junction temperature from the estimated LED junction temperature to calculate the temperature error signal. This invention adjusts the heat dissipation system by outputting a control signal, achieving closed-loop junction temperature control, improving temperature tracking control accuracy, and preventing overheating and degradation of the LED vehicle lights.
