AI Technical Summary
Existing technologies cannot effectively identify the evolution state of passivation films and cannot achieve targeted breakdown control, which can easily lead to over-excitation, thermal accumulation, or film regeneration, resulting in a decline in the long-term reliability of the system.
A temperature-current coupling control-based method is adopted, which dynamically decouples and eliminates the passivation film through high-dimensional periodic coding mapping, a film thickness prediction model of non-uniform step size response behavior, and a multi-dimensional perturbation excitation generation mechanism.
It achieves accurate identification and targeted excitation control of the passivation film, significantly improving the system's energy efficiency and safety, avoiding over-excitation and heat accumulation, and restoring the battery's micro-current output capability.
