All of these factors have a significant impact on acceleration, fuel economy, and battery degradation. However, research on the impact of the multi-layer co-optimization of the powertrain physical configuration and control on battery life has been neglected. Therefore, to fill this gap, an innovative aging-aware real-time multi-layer co-optimization method is proposed in this study. In the topology layer, a novel and improved multi-mode multi-gear configuration is proposed, and the performance differences and the intrinsic mechanism of different powertrain types are analyzed quantitatively and qualitatively. In the control layer, an advanced aging-aware fast real-time control strategy (AFRCS) is proposed. In the AFRCS, the offline optimization layer works in combination with Pareto optimization, battery life aging optimization (BLAO), and parallel computation to speed up the computational efficiency. The online mode coordination layer is used for real-time control, which improves the computational efficiency by approximately 20,000 times, and the battery life optimization is in the range of 10.22 %–12.9 %. During real-world driving cycles, the proposed configuration improves the acceleration and the battery life by an average of 50 % and 22.67 %, respectively, compared to a Toyota Prius, and it improves fuel saving by 8.82 % compared to a Honda Accord. Finally, the proposed AFRCS is verified with a hardware-in-the-loop (HIL) experiment.

Data-driven models are particularly suitable for widespread use, as they can self-learn building thermal characteristics and optimize system operation. In this study, we employed an autoregressive model to forecast short-term hourly energy demand and the corresponding water supply temperature to the heat emitters. These predictions helped to estimate generators performance and select the optimal unit to minimize energy costs while meeting heat demand. The predictive control procedure was tested on various case studies, both simulated and field-monitored, representative of the Italian housing stock. Results showed that in non-renovated buildings with radiators, the predictive control strategy can reduce operating costs by up to 20% compared to current commercial HHP controls. This improvement was mainly due to better supply temperature set-point evaluation and increased HP use. Similar benefits were observed in environmental and primary energy metrics. Conversely, in newer, well-insulated houses with low-temperature emitters, current controls are already efficient. Finally, we showed that the proposed control strategy deviates less than 3% from an ideal prediction and control in realistic on-field monitored test cases, representing a valuable trade-off between achievable benefits, data requirements, computational efforts, and implementation feasibility in real industrial HHP devices.</div></div>","PeriodicalId":11664,"journal":{"name":"Energy Conversion and Management","volume":"332 ","pages":"Article 119737"},"PeriodicalIF":9.9,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643348","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}
