Common enclosure-style battery packs without specialized venting can constrain these gases, potentially promoting thermal runaway propagation (TRP) within the module. To clarify the impact of unignited TR venting gases on TRP, this study conducted comparative experiments on LiFePO₄ modules with normal packaging (NP) and isolated venting packaging (IVP). In NP, the module’s top includes baffles allowing venting to spread, whereas IVP uses dedicated airflow channels to isolate venting. Quantitative analyses of TRP behavior, temperature, and mass loss rates were conducted under varying heating positions and states of charge (SOCs). Results indicated that NP modules exhibited faster TRP in all tests due to heat accumulation from venting gases in the semi-enclosed space between cell surfaces and packaging, compared to IVP. In the side heating scenario, TR behavior of SOC 100 % NP modules was more severe, with an average heat contribution from TR venting gases of front-end cells just before safety valve activation in back-end cells being 27.3 %, while not all cells underwent TR under IVP. Under intermediate heating, lower SOCs caused TR venting gas heat contribution to decrease from 27.4 % at SOC 100 %–8 % at SOC 50 %. These findings demonstrate that venting gases from TR cells significantly accelerate TRP in enclosed structures, highlighting the critical importance of packaging design for safety. Consequently, venting gases should be directed away from the module and effective thermal insulation measures implemented to reduce TRP risk.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"23 ","pages":"Article 100388"},"PeriodicalIF":15.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a sophisticated approach for managing an HRS powered by renewable energy sources (RESs) that addresses these uncertainties. The HRS is designed to support the simultaneous refueling of multiple hydrogen electric vehicles, including light vehicles and buses, and operates in both off-connected without access to the hydrogen market and on-connected with access to the hydrogen market. The connection to the hydrogen market allows for the purchase of hydrogen when RESs are insufficient and the sale of excess hydrogen. Additionally, a buffer-tank is integrated into the system to store surplus hydrogen, which can be converted to energy and sold to the electrical market when prices are favorable. The proposed strategy incorporates Boolean relaxations and a stochastic scenario-based approach within a model predictive control framework to enhance robustness against uncertainties and reduce computational complexity. Numerical simulations show that the strategy optimizes the use of multiple tanks for parallel refueling and ensures effective HRS operation by meeting hydrogen demands, satisfying operational constraints, minimizing costs, and maximizing profits. Furthermore, when compared to other strategies in the literature with a modeling and control perspective, incorporating degradation factors into control settings significantly reduces unnecessary electrolyzer switching, leading to a 30% decrease in operating expenses and over 2,000 fewer switching events annually, while the relaxed framework achieves nearly a 50% reduction in computation time with both open-source and commercial solvers (e.g., GUROBI).</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"23 ","pages":"Article 100393"},"PeriodicalIF":15.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163248","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 paper proposes a novel framework for assessing the flexibility of EVs under different charging control strategies through a rule-based identification of charging patterns. First, key categories of EV charging activity chains, characterized by the sequence of parking and charging activities between adjacent trips, are extracted from real-world EV operation data. Simulations are then conducted by switching charging patterns to represent three coordinated charging control methods: delayed charging, reduced-power charging, and smart charging with Time-of-Use (ToU) tariffs. These strategies are applied by modifying the charging time or charging rate within the original charging sessions. Several evaluation metrics are introduced to quantify each strategy's impact on load profile reshaping, flexibility utilization efficiency, user involvement, and energy cost saving. Comparison results show that smart charging with ToU tariffs outperforms the other two strategies, though the effectiveness of each scheme varies with charging patterns. The findings highlight the idle parking time and its ratio to the required charging time as key indicators for identifying potential EV users for coordinated charging control. Additionally, it is shown that shifting 1 % of EV charging load out of peak periods requires at least 4 % of user participation, while at least 3 % is needed for shifting 1 % of EV charging load into valley periods. The proposed pattern-based charging model and evaluation framework offer valuable insights for designing more efficient, cost-effective, and user-friendly EV charging scheduling strategies.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"23 ","pages":"Article 100367"},"PeriodicalIF":15.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For liquid hydrogen refueling stations to carve out a niche in a well-established market dominated by gaseous hydrogen refueling stations, the hydrogen selling price must be competitive. In this research, an energy-optimized design for liquid hydrogen refueling stations was proposed, focusing on reducing operating costs and mitigating potential environmental impacts. The developed design integrated three energy-saving systems into a basic liquid hydrogen refueling station: 1) a heat exchange system for hydrogen pre-cooling, 2) an organic Rankine cycle for waste heat recovery, and 3) a catalytic combustor for utilizing boil-off gas. To assess the viability of the integrated process, case studies were conducted focusing on economic, environmental, energy, and exergy performance. Consequently, the proposed design with integrated energy-saving systems demonstrated that while it increased the minimum hydrogen selling price by 5 % compared to the basic liquid hydrogen refueling station, it could reduce global warming potential by 41 %.

However, conceptualizing those systems, consisting of component and controller design processes, is a complex task. The complexity itself arises from the amount of requirements for design objectives and use-cases, which can be met inside a multidimensional parameter space. Additionally, system design and evaluation are inherently tied to coupled component and system control strategy optimization. In this context, the paper presents a fully automated active machine learning methodology applied for a combined optimization of electric machine and system controller design, considering system performance, durability, and energy consumption. During this iterative approach a stochastic optimization of a permanent magnet synchronous machine (PMSM) takes place, constrained from a nonlinear model predictive control in a model-in-the-loop system environment. The active learning is covered by a Bayesian optimization algorithm with a Gaussian process regression to determine the most suitable parameter set in terms of exploration and exploitation. To demonstrate the feasibility of this novel methodology, a thermal subsystem from an electrified state-of-the-art powertrain has been used and further optimized regarding PMSM scaling and final gear ratio. Different real-world drive scenarios from highway to city were taken into account to cover typical sport utility vehicle use-cases.

However, excessive coolant exit temperature and heat rejection rate fluctuations were observed at higher spray periods with longer intervals (IMSC-60-60I and IMSC-40-40I) and lower duty cycles (&lt;50 %). On the other hand, the IMSC strategy with shorter intervals and spray periods, i.e., IMSC-30-20I, was identified as optimal, offering a 55.7 % improvement in η<sub>ev</sub> compared to CTSC, despite a 2.8 % reduction in η<sub>th</sub>. Overall, the optimal IMSC configuration exhibited a 69.4 % higher heat rejection capacity compared to conventional air-cooled stack radiators. Furthermore, variations in η<sub>th</sub> were validated using existing correlations, and new empirical correlations for both η<sub>th</sub> and air-side heat transfer coefficient were developed, with prediction accuracies of approximately 86 % and 85 %, respectively. Additionally, the radiator's heat transfer area could be reduced by up to 76.2 %, despite a 7.5 % increase in vehicle curb weight. In summary, this study highlights the potential of using IMSC strategies for stack radiators in FC vehicles. The findings provide valuable insights for designing and implementing IMSC-enhanced radiators in real-world applications.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"23 ","pages":"Article 100384"},"PeriodicalIF":15.0,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142723607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
