The capacity to anticipate batteries for the purpose of maintaining a consistent supply of energy and the best possible use of that energy, remaining usable life (RUL), must be calculated beforehand. When it comes to accurately anticipating the battery management systems’ state of charge, we decided to forecast RUL using a random forest model.
As electric vehicles advance in electrification and intelligence, the diagnostic approach for battery faults is transitioning from individual battery cell analysis to comprehensive assessment of the entire battery system. This shift involves integrating multidimensional data to effectively identify and predict faults.
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.
The remaining life of a battery represents the number of battery cycles from its rated capacity to the end of its life . The formula is as follows: where Neol is the maximum number of battery cycles, and N represents the number of cycles of the battery.
In the absence of accurate battery parameter information, the detectability and isolation of sensor faults are successfully obtained. When the voltage sensor and current sensor fail, it will not only cause the phenomenon of overcharging and over discharging of the battery, but also reduce the accuracy of the battery system's SOC [, , ].
Over the past decade, scholars and industry experts are intensively exploring methods to monitor battery safety, spanning from materials to cell, pack and system levels and across various spectral, spatial, and temporal scopes. In this Review, we start by summarizing the mechanisms and nature of battery failures.
