Conclusions A method for diagnosing the abnormal battery charging capacity based on EV operation data was developed in this study. By establishing offline and online diagnosis systems to monitor the charging capacity, the TR caused by overcharging can be effectively identified in time. The following are the most important findings of this study.
Use CAN charging information and battery charging demand information. Compare the charge charging demand information to determine whether the charging process is normal. When time. The charging data (including charging accident data) provided by a charging pile normal and abnormal charging conditions. This method can identify more than of faults.
Abnormal Charging Process the application of the proposed fault monitoring method in the abnormal charging process. provided by BMS is shown in Figure 13. As can be seen from Figure 13, the initial SOC of the battery is 62%. When the battery has been fully charged for 88 min, BMS did not send
A statistics-based method is then used to diagnose battery charging capacity abnormity by analyzing the error distribution of large sets of data. The proposed tree-based prediction model is compared with other state-of-the-art methods and is shown to have the highest prediction accuracy. The holistic diagnosis scheme is verified using unseen data.
The authors of proposed a fault early warning method for the electric vehicle charging process based on an adaptive deep belief network. ... ... In Ref. , the authors propose online estimation of the battery model parameters such as battery state of charge, voltage, and temperature.
The calibration of the battery’s state of charge ( SOC) is inaccurate because of the inability of the battery management system (BMS) to accurately evaluate the aging of all cells. This leads to the overcharging of cells, which is one of the most common real-world causes of thermal runaway (TR) in batteries [ 5 ].
