For battery energy storage systems, this means increasing the battery''s energy capacity. This could be repowering a system following degradation or a commercial decision to increase the project''s duration.

Energy saving and emission reduction is a worldwide issue in this new century. Transportation alone accounts for 30% of total energy consumption, and it is necessary to control and reduce the energy used for travel mobility (Scarinci et al., 2017).Back in 1980s, scholars and practitioners have initiated various works on energy consumption in transportation field

Degradation stage detection and life prediction are important for battery health management and safe reuse. This study first proposes a method of detecting whether a battery has entered a rapid degradation stage without accessing historical operating data.
To the authors' knowledge, this is the first study to diagnose the battery degradation stage without accessing historical data. Subsequently, a training data selection method utilizing the t-SNE and DBSCAN algorithms is proposed to facilitate the clustering of battery data with similar physical information.
Using only one-present-cycle data, the proposed method can predict the constant current voltage-capacity curves for hundreds of future cycles, thereby achieving predictions of future battery degradation. The specific contributions are as follows:
Present battery degradation prediction research is often limited by insufficient historical data and a lack of interpretability. Moreover, these research only indicates battery degradation by predicting maximum capacity or battery lifespan, making it difficult to obtain more practically useful information.
First, for the first time, a degradation stage detection method that does not involve accessing historical data is proposed; this method can quickly classify retired batteries, particularly by detecting whether the current cycle is in a rapid degradation stage.
