The invention discloses a battery bump self-adaptive flexible two-phase liquid cold and hot out-of-control early warning method and system, and relates to the technical field of battery liquid cooling heat dissipation. Comprising the following steps of S1, collecting fitting state data of a cold plate and a battery in real time, and performing data preprocessing; s2, judging whether the battery swells or not, and identifying a swelling abnormal event; s3, self-adaptive flexible regulation and control are carried out on the battery bump working condition according to the bump abnormal event; evaluating the liquid cooling heat conduction efficiency after self-adaptive flexible regulation and control, and carrying out local heat conduction performance optimization regulation; and S4, after the local heat conduction performance optimization adjustment is completed, evaluating the collaborative heat dissipation capability margin, carrying out liquid cooling and heating runaway early warning, and implementing thermal runaway intervention measures. The problems that under the dynamic deformation working conditions of battery swelling and the like, an existing liquid cooling heat dissipation system is difficult to keep efficient heat conduction and stable attachment and lacks a real-time sensing and active early warning mechanism, so that local overheating and thermal runaway risks are difficult to restrain in time are solved.

The application provides a transformer oil acetylene free degassing detection method and system based on click chemistry, relates to the technical field of gas detection and analysis, and utilizes a first product generated through a first click chemistry reaction and a second product generated through a second click chemistry reaction as catalysts to trigger subsequent same cascade chemical amplification reactions, so that a single product molecule can catalyze the hydrolysis of a large amount of acid-sensitive substrates, a significant and measurable change in the conductivity of a mixed solution is realized, precise detection of extremely low concentration acetylene is realized, meanwhile, a second click chemistry reaction of a synchronous internal standard reagent and a trigger agent exists independently of the process of acetylene concentration detection, calculation of acetylene detection is performed, the final output is not a single first electric signal value, but a ratio of the first electric signal value and a second electric signal value, a signal ratio is obtained, interference factors are offset, online self-correction of acetylene detection is realized, and the high consistency and accuracy of detection results under different times and different batches of reagents are ensured.
