The invention discloses a lithium battery equalization method based on improved fuzzy control, which aims at solving the problems of low single variable control precision and poor fixed universe adaptability in the existing equalization method, and comprises the following steps: firstly, dividing SOC into different intervals through battery OCV-SOC characteristic analysis, and preferentially carrying out voltage equalization in an extreme SOC interval to avoid overcharge and overdischarge; sOC equalization is preferentially carried out in the middle SOC interval so as to improve the energy transfer efficiency. A voltage and SOC dual fuzzy controller is designed, a variable universe fuzzy controller is introduced to dynamically adjust an input variable universe, the universe is expanded at the initial stage of equalization to accelerate response, and the universe is shrunk at the later stage of equalization to improve precision. And further designing a self-adaptive fuzzy controller, taking the SOC mean value and the equalizing current as input, and dynamically outputting a weight coefficient of a double-fuzzy controller, thereby realizing self-adaptive switching of the equalizing strategy under different SOC intervals. According to the invention, the equalization precision and efficiency are effectively improved, and the robustness and safety of the system are enhanced.

The embodiment of the invention provides a local dynamic recoordination bit stream method and device based on multi-dynamic region division. The method comprises the following steps: generating a mixed netlist file according to a static logic and a plurality of first dynamic logics, and respectively generating a plurality of independent netlist files according to a plurality of second dynamic logics; executing a bit stream processing flow of the mixed netlist file to obtain an integral bit stream file and a plurality of first bit stream files; respectively executing bit stream processing flows of the plurality of independent netlist files to obtain a plurality of second bit stream files; and replacing the second target file in the plurality of first bit stream files with the first target file in the plurality of second bit stream files to obtain a re-coordinated bit stream file. According to the technical scheme provided by the embodiment of the invention, the previous overall region calibration process is split, each dynamic region is independently processed, and the corresponding bit stream is generated, so that the regions are ensured not to influence each other, and local bit stream reconfiguration can be realized in the subsequent use process of the FPGA.

This invention proposes a method, system, device, and readable storage medium for stress testing of a system hard drive. The method includes: collecting data on the mounted partitions of the hard drive; collecting the available capacity of each mounted partition; calculating the test duration for each partition based on the set test duration and the available capacity of each partition; performing stress tests on each partition sequentially according to the test duration; and generating logs and deleting files generated during the test after the test. Specifically, during stress testing of each partition, a method of cyclically generating files of fixed / random sizes in the corresponding partition's iotest directory is used for read / write stress testing until the time expires or the partition capacity is exhausted, at which point the test ends. This invention achieves comprehensive hard drive stress testing covering the entire system partition by creating files on each partition of the system hard drive and performing file read / write tests. This can expose early hard drive failures through stress testing, effectively reducing client-side quality issues.
