Multi-level protection method and system for lithium battery based on digital twinning

Abstract

The application discloses a kind of multi-level protection method and system of lithium battery based on digital twinning, and the application relates to the technical field of lithium battery, by identifying the working simulation event to determine multiple working simulation projects, to mark the corresponding working multi-modal data, and closed-loop optimization is carried out in combination with the working scene of lithium battery and corresponding environmental parameters, and then the degradation trajectory of lithium battery at the current time is determined in digital twinning space, improve the accuracy of the degradation trajectory of lithium battery at the current time. Mark the corresponding degradation dimension along the dynamic deduction of each degradation node, then determine multiple risk events of lithium battery in combination with causal evolution logic, and then build corresponding multi-level risk content, and cross matching is carried out in combination with the current working state of lithium battery and corresponding protection matrix, to output multiple protection measures, and further fusion the current working content of lithium battery and corresponding working sequence, improve the accuracy of multi-level protection content of lithium battery.
