AI Customer ServiceAccurate estimation of the state of health (SOH) of batteries is an important aspect of battery state estimation. Battery capacity cannot be precisely measured due to negative factors such as aging effects. To address this issue, this paper proposes a LIB’s SOH estimation method based on incremental energy analysis (IEA) and transformer.
The capacity of a lithium battery shows a degradation trend because of the side reactions that occur between the electrodes and electrolyte of the battery. Therefore, it is usually selected as a health indicator for battery degradation empirical model in the above-mentioned.
Battery capacity is a commonly used indicator to represent the health status of lithium batteries. However, the capacity regeneration is usually unavoidable due to the impact of battery “rest time” between two cycles, which leads to inaccurate prediction of the RUL.
To adaptively estimate the noise variables in the degradation model and to accurately detect the battery capacity regeneration, this article proposes a novel expectation maximization-unscented particle filter-Wilcoxon rank sum test (EM-UPF-W) approach.
To solve this problem, Pang et al. [ 25] used the multi-scale wavelet decomposition technology to separate the global degradation and local regeneration of a battery capacity series, then constructed the RUL prediction framework based on nonlinear auto regression neural network model to combine two parts of the prediction results.
Battery Parameters Battery capacity is a measure of a battery’s ability to store a certain amount of charge or energy. It represents the amount of electricity or energy generated due to electrochemical reactions in the battery. It can be defined as battery charge capacity, measured in Ah, or as battery energy capacity, measured in Wh.
