Accurate prediction of the Remaining Useful Life (RUL) of lithium-ion batteries is crucial for timely maintenance and operational efficiency in electric applications.
This paper introduces a RUL prediction approach that utilizes recent charge-discharge cycle data to estimate the remaining usable cycles.
The approach involves a signal processing pipeline and a deep learning prediction model, incorporating capacity feature calculation, denoising, and feature enhancement techniques.
The prediction model utilizes a hybrid deep learning architecture involving 1D CNN, A-LSTM, and ODE-LSTM modules to capture local signal characteristics, long-range temporal dependencies, and continuous-time dynamics of battery degradation, demonstrating superior performance in RUL prediction applications.
