Abstract: The present invention relates to a method for measuring the AC impedance of a battery in a composite power supply power system, comprising the following steps: determining the AC disturbance signal amplitude, operating the DC/DC voltage converter to generate the AC disturbance signal, collecting the output signals of the fuel cell and the lithium battery, calculating the output power of the fuel cell and the lithium battery; calculating the demand power of the load, and when the demand power is stable, calculating the impedance of the lithium battery and the fuel cell separately, otherwise, only the impedance of the fuel cell is calculated.

Abstract: An intelligent plate parts machining production line combining universal equipment and special equipment. Four special machining tools are located on first to fourth stations, respectively, and a universal machining tool is located on a fifth station. The stations are sequential from an automatic feeding device. Truss conveying devices are behind the first to fourth stations, and four mechanical arms are on the truss conveying devices. A four-axis manipulator is between the fourth and fifth stations for transferring materials between the two stations and discharging finished products. Industrial cameras are on the second-station mechanical arm and the four-axis manipulator. Waste boxes are between the first and second stations and between the fourth and fifth stations. A discharging box is on the front side of the fifth station. A scrap conveying mechanism is below the production line. Flexible clamps and sliding rail cylinders are used, so that the production line is flexible.
