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.
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
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.
Additionally if the recharge does not recover the discharge cycle in full, the battery will exhibit loss of performance and concentration of the acid can occur between plates which can lead to corrosion and loss of performance.
Such abnormal voltage data occur because the battery has experienced over-charging, over-discharging, imbalance, thermal runaway, and other faults [5, 6], causing voltage changes abnormally. Consistency anomaly detection of the battery voltage can help to achieve early warning of battery faults and avoid safety accidents in energy storage stations.
While BMS are designed to prevent over-charging by monitoring the SOC, factors like different charging modes (e.g., fast charging) and charging rates can lead to over-charge [69, 70]. Additionally, BMS misjudgment due to sensor faults can cause prolonged over-charging. The design and quality of battery cells also play a role.
If a battery is subjected to deep discharging (greater than 35%) and rapid charging the process is accelerated. Additionally if the recharge does not recover the discharge cycle in full, the …
