“…The mathematical junction between the input and the output layer is realized by a hidden layer and its neurons, where the neurons are interconnected as in Figure 12. Every neuron except the inputs consist of a sum of the products of the output O pred of the neurons in the predecessor layer and a particular weight W pred,actual between the neurons of the predecessor and the actual layer [129]: There are two basic architectures of ANNs: feed-forward networks and feedback (recurrent) networks. Meanwhile, there are three main training scenarios for ANNs: supervised, unsupervised, and hybrid.…”

“…In [129] a BPNN was used for the SoC determination based on frequency domain data. Here, the real and imaginary parts of the measured impedance, plus the frequency of each measurement are used as X1, X2, and X3 inputs of a three-input BPNN like that presented in Figure. The corresponding output layer provides with its neurons the dedicated SoC classes {c i } corresponding to the SoC specific impedance spectra.…”

“…The field of battery cell modeling and state estimation is vast, and numerous approaches with varying degrees of benefits have been developed in the past [18][19][20][21][22][23][24] Because of their simplicity and ability to capture battery dynamics, equivalent circuit model-based techniques such as Thevenin model, 25,26 the Partnership for a new generation of Vehicles model, 27,28 and the double polarization model have been popular. However, in terms of material qualities and the physical structure of the cell, these models are often difficult to comprehend.…”

“…The LFP battery has a wide voltage platform within the 20% to 90% SOC range, and the OCV difference within the voltage platform range is no more than 20 mV. The flatness of the middle section of the SOC-OCV curve, which makes system observability poor, will affect the rate of convergence of iterative algorithms such as the Kalman filter, and also reduces the accuracy of the initial SOC value acquired by the OCV-based correction method [13,14]. In addition, LFP batteries have hysteresis characteristics [15], path dependence [16], and memory effects [17].…”
