AI Customer ServiceFrom the results in Table 7, it is clear that the Bagging algorithm in Group 2 and the ExtraTree algorithm in Group 3 are the most suitable algorithms for SoC estimation of battery. As stated in Section 3.3, using filters in ML-based prediction problems can decrease the fluctuations in the estimation curve and eliminate the outlier data.
For example, the novel data-driven method of early prediction of lithium-ion battery cycle life was recently published on the journal of Nature Energy. Based on the same dataset used above, the constant-current (CC) discharge data of the first 100 cycles are required for this method.
Future research will focus on extracting features under variable charge and discharge currents, optimizing feature extraction methods, enhancing the model’s real-time application capabilities, and expanding its use in multi-variable environments, all aimed at further improving the accuracy and reliability of lithium-ion battery SOH prediction.
Based on a rational definition for battery life and RUL, a prediction algorithm is also quite necessary for battery life and RUL estimation. State estimation algorithms, including Kalman filter (KF) and particle filter (PF) have been widely used in battery RUL prediction.
In addition, neural networks appear to be promising for RUL predictions of lithium-ion batteries. The Recurrent Neural Network (RNN) is a commonly used method to predict unknown sequences. Liu et al. confirmed that the adaptive RNN shows better a learning capability than classical training algorithms, including the RVM and PF methods.
Liu et al. proposed SR-UKF algorithm on Lithium cobalt oxide battery for SoC estimation, and they claimed that robustness was increased and SoC estimation error reduced to the traditional ones . All these methods consider the process and measurement covariances as constant.
