This study systematically addresses these challenges through a comprehensive test matrix to investigate the effects of pressure, temperature, state-of-charge (SoC) windows, and charge rates (C-rates) on the evolution of expansion, resistance, and capacity behavior over the lifetime of the battery. Increasing the applied pressure between 34 and 172 kPa reduced both reversible and irreversible expansion per cycle, as well as resistance growth over time, without significantly impacting capacity fade. Electrochemical Impedance Spectroscopy (EIS) confirmed that increased pressure lowered initial solution resistance and mitigated the further growth of the solution and solid electrolyte interphase (SEI) resistance. Elevated temperature (45°C) extended battery cycle life despite an initial increase in resistance. The lifetime impedance increase under 45°C was dominated by SEI resistance. Consistent with prior studies, operating in a narrow SoC window at high SoC minimized capacity loss. Additionally, charge rates up to 2C had a limited effect on the overall degradation trends. Incremental capacity analysis (ICA) and differential voltage analysis (DVA) identified lithium inventory loss (LLI) as the primary cause of pre-knee degradation, whereas post-knee degradation resulted from a combination of LLI and anode-active material loss, particularly silicon.

Irrespective of the charging stations’ internal alternating current (AC) or direct current (DC) bus configurations, the main concern is the exponential growth in charging demands, resulting in network congestion issues. In the context of exponential EV growth and the provision of charging facilities from low-voltage distribution networks, the distribution network may require frequent upgrades to meet the rising charging demands. To avoid network congestion problems and minimize operational expenses (OE) by integrating energy storage systems (ESS) into ultra-fast charging stations (UFCS). This paper presents a techno-economic analysis of a UFCS equipped with a battery ESS (BESS). To reduce reliance on the electric grid and minimize OE, a dual-objective optimization problem is formulated and solved via grid search and dual-simplex algorithms. Analytical energy and physical BESS models are employed to evaluate the optimization matrices. The intricacies of BESS aging are examined to ensure an optimal BESS size with a more extensive lifespan than the corresponding payback period. The integrated BESS significantly reduced reliance on the grid to tackle network congestion while fulfilling charging demands. The dynamic pricing (DP) structure has proven more favorable, as the average per unit cost remains lower than the static tariff (ST). Results illustrate that integrating BESS reduces the OE and peak-to-average ratio (PAR) by 5-to-49% and 16-to-73%, respectively. Moreover, the combination of 70% BESS and 30% grid capacities outperforms the other configurations with a 73% reduction in PAR and a 49% reduction in OE before BESS reaches the end-of-life.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"24 ","pages":"Article 100411"},"PeriodicalIF":15.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143620238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work exploits the P2D model to understand the performance decay of ageing cells from a physical perspective. A complex experimental campaign combining 13 different automotive-like cycles, applied to commercial battery samples to recreate the degradation of batteries under realistic conditions, is analysed with such methodology.

Parameter evolution is then correlated with specific degradation mechanisms, related operating conditions and performance decay. A significant decrease in electrolyte conductivity and lithium solid-state diffusivity within the positive electrode are detected, progressively inducing heterogeneous operation and worsening of both efficiency and capacity retention.

Reconfigurable SC systems (RSSs) are considered a promising solution to significantly improve energy utilization rate. However, the existing RSSs are unable to maximize energy utilization and lack effective equalization capability. Moreover, the surge phenomenon is common in the RSSs, which will lead to the power device failure. To tackle these challenges, a novel RSS is proposed, integrating series-parallel reconfiguration, reconfiguration equalization, and surge current suppression. This innovative approach enables achieving ultra-high energy utilization of the SCs while significantly improving voltage consistency. Furthermore, the surge current during the mode-switching process can be effectively suppressed. Experimental results demonstrate that the RSS achieves an impressive energy utilization rate of 93.7 %, which is 137.8 % higher than the fixed-connected supercapacitor pack, and 8.8 %–16.7 % higher than the existing RSSs.
