title = "Overcharge Detection of Lithium-ion Battery Based on Vibration Signal",
abstract = "Battery safety is one of the most crucial issues in the utilization of Lithium ion batteries (LIBs). Short circuit, overcharge, and overheat are three common field failures of LIBs and overcharge is the most important common failure. To accurately detect the overcharge of LIBs, the experiments are carried out to obtain the vibration signals of LIBs under different state of charge (SOC) including overcharge. The spectrum of the vibration signals is analyzed using fast Fourier transform (FFT). The results show that the magnitude and the amplitude range of the vibration signals generated by the LIB will increase if the LIB continues to be charged when overcharged. In addition, a high frequency vibration signal which is about 9.5 kHz will occur when the LIB is overcharged, which could be used as an indicator to detect the battery overcharge.",
