BATTERY CHARGING Introduction The circuitry to recharge the batteries in a portable product is an important part of any power supply design. The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time. This chapter will present charging methods, end-of-charge-detection techniques, and

The voltage profile of a battery during charging and discharging can provide insights into its health. As batteries degrade, their voltage response may deviate from the expected behaviour. Monitoring voltage patterns and comparing them with a healthy reference can help in estimating the SOH indirectly. Capacity fade refers to the reduction in

In practice, the complex work environment, dynamic operating conditions and low sensor accuracy lead to data quality issues, and the predictive performance of the models is lower than expected. Moreover, commercial confidentiality and privacy protection limit the amount of historical data available for battery detection .
Battery degradation is inevitable, and it will also affect various battery parameters, and the existing sensor fault detection and isolation (FDI) methods ignore this important factor [, , ]. Tran et al. took battery degradation into account and proposed a sensor FDI scheme based on a first-order RC-equivalent circuit model.
At present, the analysis and prediction methods for battery failure are mainly divided into three categories: data-driven, model-based, and threshold-based. The three methods have different characteristics and limitations due to their different mechanisms. This paper first introduces the types and principles of battery faults.
Battery degradation refers to the progressive loss of a battery’s capacity and performance over time, presenting a significant challenge in various applications relying on stored energy . Figure 1 shows the battery degradation mechanism. Several factors contribute to battery degradation.
In recent years, data-driven approaches have emerged as powerful tools for estimating battery degradation. Leveraging vast amounts of historical and real-time data, these techniques offer a holistic understanding of battery health and degradation patterns .
