The mechanical performance (modulus and density) of the electrode is dynamically changing during cycling, which will influence the dispersion characteristics of ultrasonic guided waves in lithium-ion battery. Based on this, the intrinsic connection between the SOC and the guided wave dispersion curve of lithium-ion battery is numerically analyzed.
Li et al. [25, 26] investigated the intrinsic connection between multi-feature indicators of ultrasonic guided waves and the SOC of lithium-ion batteries, and proposed an adaptive-FNN-XGBoost model to realize the estimation of the SOC of lithium-ion batteries.
Hao et al. [29, 30] captured the guided wave information of lithium-ion batteries during the cycle, by employing piezoelectric transducer excitation and laser Doppler vibrometer reception, and extracted the regular distribution curves between acoustic parameters and SOC.
Experimental tests with customized battery to validate the analytical acoustic model. This work presents the analytical acoustic model to investigate the interaction mechanism between the state of charge (SOC) of lithium-ion battery and the propagation characteristics of ultrasonic guided waves.
