However, limited battery capacity and drive range are known as the main obstacles to the widespread usage of EVs. Signalized intersections are among the bottleneck situations, in which the transportation systems are away from their optimal operation point. Eco-driving is an effective solution for dealing with idle stop-and-go issue before the signalized intersections, which is attainable thanks to the merits of advanced connected vehicle (ACV) technology. In this study, an eco-cooperative driving strategy is presented in proximity to the signalized intersections, considering driver comfort. First, Virginia Tech’s microscopic (VT-Micro) model is developed, taking into account road slope and regenerative braking energy. Then, using the model, all optimal acceleration and deceleration levels for uphill, flat, and downhill scenarios with consideration of driver comfort are determined. Finally, the effectiveness of the eco-cooperative driving strategy is examined.","PeriodicalId":48518,"journal":{"name":"IET Electrical Systems in Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/els2/5574313","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-efficiency interior PM (IPM) generator has been designed. It is suggested to use a three-phase, 12-/10-pole generator for the auxiliary power unit application. In this regard, to compute the components of the flux density distribution in the air gap of an IPM generator, a hybrid analytical model is employed. The unique aspects of this work include the development of a 2-dimensional (2-D) analytical method to determine the air gap magnetic flux density in the IPM generator, as well as the first-ever replacement of the stator slot with surface currents without the need for a repetitive loop. The rotor body bore receives 1-dimensional (1-D) analytical IPMs first transferred using the magnetic equivalent circuit (MEC) model. After that, the 2-D analysis is modified to take the stator slot’s impacts into account by adding virtual surface currents (VSCs). Using boundary conditions and the Laplace/Poisson equations, the radial and tangential flux components of the flux density distribution in the air gap IPM generator were computed. The suggested method and the acquired findings have been validated by the finite element method (FEM), analytical model, and experimental results, indicating that the IPM generator is a promising option for electric vehicle (EV) auxiliary power unit applications.","PeriodicalId":48518,"journal":{"name":"IET Electrical Systems in Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/els2/6472337","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key electrical power technologies are also being developed to enable the realization of these new aircraft types. The Pyrofuse protection device is a nonresettable protection device (NRPD) that offers desirable features for use within small electric aircraft applications. The components used in the Pyrofuse are also currently available at the intended power levels and at low cost. However, the nonresettable aspect of the device represents a challenge in the certification process for its use in eVTOL electrical system protection, although there is a current shortage of published literature on this aspect. Accordingly, this paper provides the first document-based review of certification compliance assessment for the use of NRPDs in an eVTOL environment. This assessment shows that devices such as Pyrofuses can achieve airworthiness in a range of roles as the primary protection for eVTOL electrical power system (EPS). However, this airworthiness is highly dependent on the physical design of the aircraft design, the proposed location of NRPDs, and the immunity to common mode and common cause failures.","PeriodicalId":48518,"journal":{"name":"IET Electrical Systems in Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/els2/7218316","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, due to the low efficiency of energy management systems’ multiobjective weighting algorithm and the comparison of different configuration performance under specific component parameters, it is difficult to fully demonstrate the performance potential of configurations. To solve the above problems, multiple allowable component parameter schemes need to be considered. This article introduces a multiobjective evaluation method for hybrid powertrain configurations based on the nondominated sorting dynamic programming algorithm and employs parameter selection and collaborative energy management strategy optimization to overcome the challenge of large computational volume. Through the multiobjective Pareto front of fuel economy and battery SoH (state of health) changes, an effective comparison and analysis of the performance of two hybrid powertrain configurations were conducted. The results reveal that, for an 18-ton urban bus, under equivalent variations in battery SoH, the power-split configuration demonstrates an average fuel consumption reduction of 10.7% compared to the series-parallel configuration. The comparison results of various parameter configuration combinations indicate that the power-split configuration outperforms the series-parallel configuration in urban driving conditions. The aforementioned conclusions also provide reference for the selection of configuration schemes for similar types of commercial vehicles.","PeriodicalId":48518,"journal":{"name":"IET Electrical Systems in Transportation","volume":"2025 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/els2/6520822","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143533286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the electrostatic repulsion between conductive particles, the EHD cannot form a jet stably using conductive materials. Herein, an improved electric field-driven direct writing (EDW) method is proposed, which utilizes the Taylor cone in contact with substrates to print directly but not form a jet. This strategy avoids the unstable electric jet printing with conductive ink and enables the fabrication of micro-scale, large-area conductive structures. In this study, the effects of printing speed on the line width, resistance of the Ag nanoparticles (AgNPs) and Ag nanowires (AgNWs) conductive structures were investigated. The mechanism of AgNWs arrangement and the relationship between arrangement and resistivity was also deeply analyzed. The final fabricated AgNPs and AgNWs conductive structures were with minimum line widths of 81.0 μm and 78.6 μm, the resistivities of 8.40 × 10-7 Ω·m and 7.78 × 10-7 Ω·m separately. Furthermore, interdigital electrodes with a line width of 380 μm were fabricated using AgNPs ink, and flexible electrodes which can maintain stable resistance when bent at 180° were printed with AgNWs ink. This demonstrated the good applicability of EDW printing in the fabrication of microscale silver conductive structures.","PeriodicalId":48518,"journal":{"name":"IET Electrical Systems in Transportation","volume":"2023 49","pages":"251-255"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147918650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
