Additionally, applying indirect measurement methods to the metrological verification of charging piles proves difficult, as the conversion efficiency of the charging module cannot be evaluated indirectly and accurately. This paper proposes a method for analyzing conversion efficiency based on unilateral data from the charging module. By utilizing the input and output power of the charging module, an indirect measurement model of conversion efficiency is established using black-box modeling theory. The model parameters are calculated through cross-validation and least squares methods. Subsequently, the transfer comparison method of uncertainty is employed to validate the model\u2019s rationality. The experimental results demonstrate that the established model successfully passes rationality verification across the entire power output range, with a measurement error of less than 0.3%. This confirms the feasibility and accuracy of both the model and the method, effectively meeting the indirect measurement requirements for the conversion efficiency of the charging module.<\/jats:p>","DOI":"10.1177\/14727978251314269","type":"journal-article","created":{"date-parts":[[2025,5,18]],"date-time":"2025-05-18T23:41:27Z","timestamp":1747611687000},"page":"2491-2501","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Conversion efficiency analysis method based on single-sided data of charging modules"],"prefix":"10.1177","volume":"25","author":[{"given":"Jin","family":"Bao","sequence":"first","affiliation":[]},{"given":"Zhichong","family":"Guo","sequence":"additional","affiliation":[{"name":"Southeast University"}]},{"given":"Zhixin","family":"Li","sequence":"additional","affiliation":[]}],"member":"179","published-online":{"date-parts":[[2025,1,18]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2024.3464591"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TTE.2023.3239224"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TEC.2024.3381280"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.est.2022.105013"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3233\/JCM-247302"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2021.3105689"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/JESTIE.2023.3285535"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/OJPEL.2024.3466936"},{"key":"e_1_3_2_10_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1109\/TIM.2022.3201940","article-title":"Error modeling and anomaly detection of smart electricity meter using TSVD+L method","volume":"71","author":"Chen L","year":"2022","unstructured":"Chen L, Lao K -W, Ma Y, et al.
