However, in MES routing and Vehicle-to-Grid applications (such as energy arbitrage), the large-scale routing problem involving multiple vehicles and nodes encompasses high-dimensional spatiotemporal decision variables, making it challenging for general commercial solvers to solve efficiently. To address this challenge, we develop an improved time–space network-based model that uses feasible spatiotemporal arcs to represent the routing schemes for MES throughout the entire scheduling period. Furthermore, we propose an adaptive spatiotemporal clustering algorithm based on time–space network aggregation-split to solve the model quickly. In the aggregation phase, given the lower bound of cluster quantities, nodes with closely related spatiotemporal distances are clustered into one representative node. During the split phase, we design a spatiotemporal envelope method to identify nodes with potential arbitrage opportunities in each cluster and classify them into a separate cluster. We apply the proposed model and algorithm to the energy arbitrage of MES within the California power grid. The results reveal that, compared to the commercial solver, the proposed algorithm significantly reduces the average time overhead by 92.7%, while only sacrificing 0.9% in optimality in more than 300 daily scheduling cases.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"26 ","pages":"Article 100478"},"PeriodicalIF":17.0,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158652","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}

Therefore, understanding the energy conversion mechanisms in both the inverter and motor is essential for accurately modeling energy consumption. However, in previous studies, real-world driving data are often limited, making it challenging to fully analyze the complex and nonlinear relationships within each conversion component. In this study, we collected input–output data from the inverters and motors of fifty-four BEVs, measured repeatedly over time. The data revealed a piecewise nonlinear relationship between input and output, prompting us to partition the models by different phases: propulsion, regeneration, and battery status. For each phase, we applied linear mixed-effects models to account for the hierarchical structure of the data, estimating coefficients separately for the inverter and motor using a randomly selected 75% of the dataset. Through this component-level modeling approach, the models not only capture component-level random-effect parameters but also effectively model the nonlinear energy conversion characteristics at the component level. The two models were then integrated to estimate the total driving energy consumption of the BEVs, and the results were validated against actual observations using the total driving energy from the remaining 25% of the dataset. Model performance was evaluated using the Total Consumption Estimation Rate (TCER) and Mean Absolute Percentage Error (MAPE). The proposed model achieved at least 95.27% in TCER and 86.34% in MAPE, outperforming existing approaches with a 20% higher TCER and an MAPE approximately ten times lower on average. The comparison demonstrated that our model accurately estimates driving energy consumption, as it effectively captured the heterogeneous and nonlinear relationships between input and output energy for each component.</div></div>","PeriodicalId":36355,"journal":{"name":"Etransportation","volume":"26 ","pages":"Article 100472"},"PeriodicalIF":17.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158651","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}

In this study, we experimentally reproduced spontaneous ignition in LFP modules under conditions of BMS failure and state of charge (SOC) mismatch. Our results show that, although a single LFP cell does not self-ignite during TR, module-level thermal runaway propagation (TRP) can concentrate heat and accumulate electrolytes, thereby creating conditions favorable for ignition. Two primary ignition mechanisms were identified: (1) frictional sparks arising from safety valve ruptures, and (2) arc triggered by pooled electrolytes that cause external short circuits. Furthermore, TRP accelerates heat accumulation and mechanical expansion, forming a positive feedback loop that intensifies fire hazards. Notably, the TRP time interval between successive internal rolls was reduced by 85.5 % (from 241 s to 35 s) once ignition occurred, while the module expansion force increased by 136.3 % compared with the pre-TR state (from 167.4 kgf to 395.6 kgf).

The RTRM is fabricated by uniformly dispersing conductive fillers of short-cut carbon fibers (CCFs) in a blended plastic matrix of low-density polyethylene (LDPE) and ultra-high molecular weight polyethylene (UHMWPE) through solution casting. Benefiting from the large thermal expansion provided by LDPE and good structural reproducibility given rise by the ultra-high melt viscosity of UHMWPE, the as-fabricated RTRM exhibits a strong and reversible positive temperature coefficient (PTC) effect, with its resistivity increasing sharply by 7.1 orders of magnitude at 110–120 °C and returning to the initial value reversibly upon cooling down even after 30 thermal cycles. As a result, the LiFePO<sub>4</sub> cathode with the RTRM demonstrates a reversible temperature-switching behavior by spontaneously halting the electrode reaction at elevated temperatures and resuming the electrode reaction upon cooling, thereby providing reversible thermal protection for LIBs.
