However, the mechanism of in-plane temperature gradient caused by high current on battery degradation is still unclear. In this study, the in-plane temperature gradient is artificially constructed between battery tabs and bottom region. Then, the fast-charging cycling test is performed. Post-mortem analysis after battery cycling is carried out to obtain the anode surface morphology and elemental distribution. A three-dimensional electrochemical model is developed to obtain the internal parameter distributions during fast charging. The results indicate that the battery degradation process can be divided into three stages: in-plane current density gradient stage, in-plane temperature gradient stage, and emergence of degradation factors stage. A spatial matching criterion between in-plane temperature gradient and in-plane current density gradient is proposed to suppress battery degradation, where optimal performance is achieved when high current density region coincide with high temperature region. Specifically, the in-plane temperature gradient with high temperature at the high current density tabs and low temperature at the low current density bottom region enhances battery fast charging performance, maintaining over 90% capacity after 50 cycles at 2C charging rate. However, an in-plane temperature gradient in the opposite direction can lead to lithium plating and material cracking, with a 34.3% capacity loss after just 5 cycles. Additionally, the low-temperature discharge tests demonstrate that achieving the spatial matching criterion can enhance battery discharge performance. Specifically, the discharge capacity increases by 8% at −20 ​°C. This study provides a novel temperature-regulation-based approach for reducing battery polarization.</div></div>","PeriodicalId":100596,"journal":{"name":"Green Energy and Intelligent Transportation","volume":"4 6","pages":"Article 100352"},"PeriodicalIF":16.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159720","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}

This capability effectively alleviates traffic congestion and decreases energy usage through smoother and more efficient vehicle operation. However, achieving autonomous docking for AMBs poses significant challenges, including the need for precise localization in both horizontal and vertical dimensions and the ability to manage dynamic persistent obstacles in close-range scenarios. Existing Light Detection and Ranging (LiDAR)-based Simultaneous Localization and Mapping (SLAM) algorithms, such as LIO-SAM, perform well in static environments but encounter limitations in dynamic scenarios, particularly with occlusions and vertical drift during AMB docking. In this paper, we propose an enhanced LiDAR-Inertial Measurement Unit (IMU) SLAM framework focused on improving localization accuracy and robustness during AMB docking. Key contributions include: (1) A two-stage scan-to-map matching method with ground constraints to reduce z-axis drift; (2) A factor graph optimization strategy integrating IMU roll and pitch constraints and periodic resetting to mitigate long-term drift; (3) A deep learning-based front vehicle detection and point cloud filtering mechanism to reduce occlusion effects. Experimental evaluations on single-vehicle and dual-vehicle datasets demonstrate that our method significantly reduces Absolute Pose Error (APE) and Relative Pose Error (RPE) compared to existing methods. These results highlight the framework's ability to address the unique challenges of AMB docking, therefore helping alleviate traffic congestion and reduce energy consumption.</div></div>","PeriodicalId":100596,"journal":{"name":"Green Energy and Intelligent Transportation","volume":"4 6","pages":"Article 100343"},"PeriodicalIF":16.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145159721","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}
