This paper presents a transformative methodology that harnesses the power of digital twin (DT) technology for advanced condition monitoring lithium-ion batteries (LIBs) in electric vehicles (EVs). In contrast to conventional solutions, our approach eliminates need calibrate sensors or add additional hardware circuits. The replica works seamlessly alongside embedded battery management system (BMS) an EV, delivering real-time signals monitoring. Our is significant step forward ensuring efficiency and sustainability EVs, which play essential role reducing carbon emissions. A core innovation lies integration into process, reshaping landscape energy storage alternative sources such as batteries. comprehensive leverages cloud-based IoT network combines both physical components provide holistic solution. side encompasses offline modeling, where long short-term memory (LSTM) algorithm trained with various learning rates (LRs) optimized by three types optimizers ensures precise state-of-charge (SOC) predictions. On side, takes center stage, enabling prediction activity. particularly innovative aspect utilization time-series generative adversarial (TS-GAN) generate synthetic data complement process. pioneering use TS-GAN offers effective solution challenge limited availability, thus enhancing system’s predictive capabilities. By integrating these elements, enables analysis behavior. innovation—particularly application generation—significantly contributes optimizing performance, safety, extending longevity EVs. Furthermore, model developed this research serves benchmark future utilization. According statistical tests, has high level precision. Its exceptional safety performance reduced consumption offer promising prospects sustainable efficient solutions. signifies pivotal towards realizing cleaner more through EV management.
