Abstract

This study presents the development and performance evaluation of a digital twin framework for Electric Vehicle Grid Integration (EVGI) to advance e-mobility and renewable energy integration. The framework integrates a state-of-the-art 4G/5G cellular and LoRa-based communication infrastructure , enabling seamless data exchange and real-time monitoring through a cloud-based dashboard. A multi-campus testbed validates EVGI interactions with a cyber-physical system, comprising photovoltaic (PV) systems, battery storage, and an EV and Electric Vehicle Supply Equipment (EVSE). Performance is evaluated based on round-trip latency and data packet collisions (losses), and connection stability. Results demonstrate that 4G cellular networks achieve round-trip latency as low as 70 ms with superior connection stability compared to narrowband Internet of Things (NB-IoT), while 5G is projected to further enhance performance. This work highlights the potential of digital twins to unify smart communication technologies and renewable energy resources, providing a scalable approach to advancing EVGI and supporting the energy transition.
