Hybrid energy systems, integrating batteries, fuel cells, or solar power, offer promising solutions but pose challenges in accurately measuring efficiency. The proposed Measurement Scale Bench is crucial for evaluating traction systems powered by hybrid sources. It simulates real-world scenarios, balancing energy management through hydrogen fuel cells and batteries. The system comprises three blocks: one for fuel cells, one for batteries, and one for propulsion, hydrogen consumption measurement, and motor performance evaluation. Experimental tests validate its effectiveness in replicating urban and exurban cycles, making it an ideal scale model for hybrid vehicles, following the UNI EN 1986–1:1998. It reveals consistent behaviour between engine energy demand, speed variations, and energy storage responses, providing valuable insights for hybrid vehicle development. Moreover, the bench's modularity not only supports diverse system configurations but also serves as an educational tool, inspiring and promoting innovation in sustainable transportation.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101433"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed conceptual model was developed based on a thorough review of the literature and documentary research to provide practical insights for educators and administrators in enhancing the quality of laboratory activities. Based on the results of the literature and documentary research, the conceptual model focusing on laboratory activities in professional education included value stream mapping (VSM), defined here as a lean management tool used to visualize, analyze, and improve the flow of materials and information required to bring a product or service to a customer. VSM can provide a comprehensive view of the entire teaching-learning process in laboratory activities, helping the referred institutions identify areas of waste, inefficiency, and opportunities for continuous improvement.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"38 ","pages":"Article 101327"},"PeriodicalIF":0.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
