These discussions are often grounded in a specific use case; however, given the need to electrify the wider transport sector it is evident that we must consider systems in a holistic fashion. When designed adequately, the hybridisation of power sources within automotive applications has been demonstrated to positively impact fuel cell efficiency, durability, and cost, while having potential benefits for the safety of vehicles. In this paper, the impact of the fuel cell to battery hybridisation degree is explored through the key design parameter of system mass. Different fuel cell electric hybrid vehicle (FCHEV) scenarios of various hydridisation degrees, including light-duty vehicles (LDVs), Class 8 heavy goods vehicles (HGVs), and buses are modelled to enable the appropriate sizing of the proton exchange membrane (PEMFC) stack and lithiumion battery (LiB) pack and additional balance of plant. The operating conditions of the modelled PEMFC stack and battery pack are then varied under a range of relevant drive cycles to identify the relative performance of the systems. By extending the model further and incorporating a feedback loop, we are able to remove the need to include estimated vehicle masses a priori enabling improving the speed and accuracy of the model as an analysis tool for vehicle mass and performance estimation.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"3 1","pages":"59-72"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10488350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140340076","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}

This article initially presents a method for fabricating ZMBs utilizing interdigitated electrodes, employing advanced techniques such as 3D printing, screen printing, laser etching, and electrodeposition. These methodologies play a crucial role in mitigating anode-related issues, consequently enhancing battery performance. Subsequently, the challenges encountered by ZMBs anodes, including dendrite formation, corrosion passivation, hydrogen evolution, and Zn cycle exfoliation, are thoroughly examined. Lastly, a comprehensive strategy for stabilizing the anode is delineated, encompassing anode material selection, anode structure construction, interface engineering, and electrolyte optimization. In essence, the preparation and fine-tuning of ZMBs present ongoing challenges. With continued research and development efforts, it is anticipated that ZMBs will attain efficient, stable, and secure performance on the microscale, offering enduring and dependable energy solutions for applications in miniature electronic devices and wearable technology.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"3 1","pages":"12-27"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10488353","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140339978","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}

Thus, an accurate method needs to be developed to estimate the battery state of health (SOH). Existing SOH estimation methods in recent literature mainly fall into two categories: model-based and datadriven methods. Model-based methods attempt to expand the original battery model by taking into account various factors affecting the battery degradation. Data-driven methods aim to characterize the relation between battery SOH and various health indicators by machine learning. Once the training process has been completed, such data-driven methods are less complex to implement than model-based methods, making them more promising for practical applications.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"2 4","pages":"257-257"},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10376445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139060264","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}
