AI Technical Summary
Existing single-cell fault early warning technologies for energy storage power stations rely on a single operating parameter and fail to incorporate the battery's electrochemical response characteristics, resulting in serious issues of missed and false alarms. Furthermore, the models have weak generalization capabilities and cannot meet the requirements for long-term, high-safety-level operation.
By extracting time-frequency domain features, relaxing analysis, capacity differential benchmark verification and tensor coupling, multidimensional health features are constructed, and an early warning network is trained in conjunction with electrochemical mechanisms to improve the accuracy and efficiency of fault early warning.
It significantly improves the ability to identify fault signals, reduces missed and false alarms, enhances the generalization ability of the model, improves the efficiency and accuracy of fault early warning, and provides reliable protection for the safe and stable operation of energy storage power stations.
