With DWC systems installed on roadways, they constitute a charging infrastructure or electrified roads (eRoads) that have many advantages. For instance, the large battery size of heavy-duty EVs can significantly be downsized due to charging-while-driving. However, a high power demand of the DWC system, especially during traffic rush periods, could lead to voltage instability in the grid and undesirable power demand curves. In this paper, a model for the power demand is developed to predict the DWC system's power demand at various levels of EV penetration rate. The DWC power demand profile in the chosen 550 km section of a major highway in Canada is simulated. Solar photovoltaic (PV) panels are integrated with the DWC, and the integrated system is optimized to mitigate the peak power demand on the electrical grid. With solar panels of 55,000 kW rated capacity installed along roadsides in the study region, the peak power demand on the electrical grid is reduced from 167.5 to 136.1 MW or by 18.7 % at an EV penetration rate of 30 % under monthly average daily solar radiation in July. It is evidenced that solar PV power has effectively smoothed the peak power demand on the grid. Moreover, the locally generated renewable power could help ease off expensive grid upgrades and expansions for the eRoad. Also, the economic feasibility of the solar PV integrated DWC system is assessed using cost analysis metrics.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"7 ","pages":"Article 100092"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a complex dynamic system, the charging and discharging process of LiBs involves the evolution of multiphysics fields, such as concentration, electricity, and stress. For quantitative analysis of the internal mechanisms of LiBs, as well as the development guidance and performance prediction of high-performance batteries, modeling has advantages that cannot be matched by traditional experimental methods. Major research efforts in the past decades have made significant strides in modeling the internal processes and physical field evolution of LiBs. Importantly, the scattered ideas need to be integrated into a structured framework to form a complete LiBs multi-physical field model. This work reviews important advances in LiBs modeling from the perspectives of describing the internal processes of the battery and portraying the evolution of the physical field. First, quantitative descriptions of the charging and discharging behaviors and the side reactions are reviewed to investigate the battery reaction mechanisms. In addition, the characterization of the evolution of the stress and temperature fields within the battery as well as the coupling between them and the internal reactions are discussed. Finally, some suggestions for future improvements in the modeling are given, ranging from equation optimization to parameter acquisition and the application of artificial intelligence. It is hoped that this work will facilitate the development of models with sufficient accuracy and efficient computational cost to provide guidance for the improvement of LiBs.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"6 ","pages":"Article 100076"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
