Summary: AC pulse heating is a low-energy and high-efficiency preheating method for lithium-ion batteries. In this study, a dual RC model and a thermal model were used to predict the battery temperature and negative electrode potential. The upper bound of heating current (UBHC) was determined by the criteria of negative electrode potential reaching 0 V, indicating lithium plating. The proposed self-adaptive AC pulse heating strategy improved the heating efficiency compared to constant amplitude pulse heating.

Summary: This study investigates the temperature rise and heat dissipation in CFRP laminates containing an embedded pouch lithium-ion polymer battery. Experimental testing and finite element modeling show that CFRP material has a cooling effect on embedded batteries due to heat dissipation from the thermal conductivity of carbon fibers. The surface temperature of the pouch LiPo battery embedded in carbon-epoxy laminates only increased by a few degrees during discharging. FE modeling accurately predicts the temperature rise in energy storage composites, considering battery discharge rate, capacity, and laminate thickness. Safe design limits for energy storage laminates with batteries are defined to prevent excessive temperatures.

Summary: This study reviews the current state-of-the-art self-heating methods and proposes the heating triangle as a new quantitative indicator for comparing self-heating methods. The heating triangle considers three fundamental metrics: specific heating rate, coefficient of performance, and specific temperature difference, enabling a quantitative assessment of self-heating methods. The analysis shows that similar metrics are observed for the same type of self-heating method, supporting the universality of the proposed indicator. The proposed heating triangle provides a standardized approach to compare heating methods and drive innovation.

Summary: In recent years, digital twins for large-scale and investment-intensive Li-ion battery systems in marine and stationary applications have gained increasing interest. Considering electrical cell-to-cell variations (CtCVs) within the battery model of such a digital twin offers advantages in model-based optimization and predictive maintenance. However, existing approaches for the characterization and modeling of CtCVs are not suitable for large-scale systems. This paper presents a holistic tool chain consisting of a non-destructive method for in-situ determination of resistance and capacity distributions, parameterization of a multi-cell battery model, and simplification through multivariate statistical analysis.

Summary: Large-scale battery energy storage systems (BESS) are already important in ancillary service markets worldwide, with batteries being suitable for applications with fast response times. However, the overall system response time of current BESS for future grid services has not been extensively studied. Measurements of a 6 MW BESS's inverters show that the response times can meet current standards even with older hardware, but hardware upgrades may be necessary for even faster future grid services.

Summary: Electric vehicles are becoming dominant in the global automobile market due to their environmental friendliness. This paper creates standard load profiles for different power levels, station sizes, and operating environments based on a large-scale empirical dataset. The study reveals that the average power per charge point increases with rated station power, especially for power above 100 kW, and decreases with the number of charge points per station for AC chargers. It also shows how the shape of the power curve largely depends on the station environment, with urban settings experiencing the highest average power of 0.71 kW on average, resulting in an annual energy sale of 6.2 MWh. These findings suggest that the rated grid capacity can be lower than the sum of the rated power of each charge point.
