Такой подход позволяет сети Колмогорова-Арнольда гибко адаптироваться к сложным структурам данных, обеспечивая точную оценку уровня заряда. Чтобы объективно оценить эффективность алгоритма, были проведены эксперименты на реальных наборах данных, направленные на анализ точности оценки уровня заряда аккумулятора при доверительных интервалах 95%, 90% и 85%. Результаты испытаний при различных циклах заряда-разряда показали, что предложенный метод достигает высокой точности и сохраняет стабильность в процессе работы. Предлагаемый метод снижает максимальную ошибку как минимум на 4,26% и значительно улучшает такие показатели, как средняя абсолютная ошибка и среднеквадратичная ошибка. Таким образом, полученные результаты подтверждают эффективность и инновационность сети Колмогорова-Арнольда в управлении энергией. Данный метод обладает высоким потенциалом в управлении энергетическими системами и может быть эффективно внедрен в области, требующие точного прогнозирования временных рядов, включая системы умного дома, электромобили и промышленные устройства. Дальнейшие исследования будут сосредоточены на оптимизации архитектуры сети и расширении ее практического использования. Примечательно, что этот метод может быть гибко адаптирован к различным типам аккумуляторов и энергетических систем, что значительно расширяет его применение в реальных условиях.</p></abstract><trans-abstract xml:lang="en"><p>This study aims to thoroughly examine the potential of the Kolmogorov-Arnold Network (KAN) and its application to improving energy management efﬁciency, particularly in lithium-ion batteries. The study employs a novel method that utilizes one-dimensional adaptive activation functions parameterized by splines, in contrast to traditional neural networks, where activation functions are ﬁxed. Traditional methods for activation function selection are based on empirical approaches and do not guarantee accurate approximation, potentially leading to suboptimal results. This approach enables the KAN to ﬂexibly adapt to complex data structures, ensuring precise state-of-charge estimation. To objectively evaluate the algorithm's effectiveness, experiments were conducted on real datasets, focusing on analyzing the accuracy of state-of-charge estimation at conﬁdence intervals of 95%, 90%, and 85%. The test results for various charge-discharge cycles demonstrated that the proposed method achieves high accuracy and maintains stability throughout the operation. The proposed method reduces the maximum error by at least 4.26% and signiﬁcantly improves key performance metrics such as Mean Absolute Error, Root Mean Square Error. Thus, the obtained results conﬁrm the efﬁciency and innovative nature of the KAN in energy management. This method holds great potential for energy management and can be effectively implemented in areas requiring precise time-series forecasting, including smart home systems, electric vehicles, and industrial devices. Future research will optimize the network architecture and expand its practical applications. Signiﬁ-cantly, this method can be ﬂexibly adapted to different types of batteries and energy systems, broadening its applicability in real-world conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>степень заряда</kwd><kwd>сеть Колмогорова-Арнольда</kwd><kwd>накопитель энергии</kwd><kwd>нейронная сеть</kwd><kwd>интервал предсказания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>state of charge</kwd><kwd>Kolmogorov-Arnold networks</kwd><kwd>energy storage</kwd><kwd>neural network</kwd><kwd>prediction interval</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была профинансирована за счет гранта Министерства науки и высшего образования Российской Федерации (Проект № FZZ–2024–0003), частично за счет Национальной Программы поддержки иностранных специалистов в Китае (грант DL2023161002L), кроме того была поддержана Фондом естественных наук провинции Хунань (грант 2024JJ3033).</funding-statement><funding-statement xml:lang="en">The work was funded by a grant from the Ministry of Science and Higher Education of the Russian Federation (Project No. FZZZ–2024–0003), in part by the National Foreign Experts Program of China under Grant DL2023161002L and additionally supported by the Natural Science Foundation of Hunan Province of China under Grant 2024JJ3033.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chen Zhilong, He Ting, Mao Yingzhe, Zhu Wenlong, Xiong Yifeng, Wang Shen, et al.
