Summary: The ageing of Lithium-ion batteries depends on their operation during charging, discharging, and rest phases, and can be forecasted to determine the state of health (SOH) of the battery. This SOH forecasting is valuable for fleet managers of battery electric vehicle (BEV) fleets to plan vehicle replacement and optimize operational strategies. However, there are limitations in the applicability and comparability of existing models due to different data sets, metrics, output values, and forecast horizons.

Summary: This study proposes a state-of-health (SOH) attenuation model considering driving mileage and seasonal temperature for battery health estimation, which is significant for battery pack management and maintenance. The variable forgetting factor recursive least square (VFFRLS) algorithm is used for battery model parameter identification and the extended Kalman-particle filter (EPF) algorithm is proposed for online capacity estimation. The proposed model and algorithm are verified using actual vehicle data over nine months. The experimental results demonstrate the accurate estimation of model parameters and capacity through the proposed algorithm, and the decrease in average capacity of the battery module with total mileage. The compensation of monthly driving mileage and ambient temperature factors effectively improves the accuracy of the SOH model.

Summary: With the increase in the number of electric vehicles, battery swapping is seen as promising due to its short waiting time. However, it is challenging to achieve efficient scheduling in a large scale battery swap station due to the uncertainty of the power grid and EV behavior. To address this, a new bi-level scheduling model is proposed, combining deep reinforcement learning for optimal power allocation and MILP subproblems for battery dispatching. Experimental results show excellent performance and cost reduction, benefiting both the battery swap station and the power grid in peak shaving and valley filling.
