Abstract

This study explores the integration of electric vehicles with photovoltaic systems in a building-level energy management framework, utilizing an Internet of Things-based system for real-time monitoring and optimization. The proposed system is implemented using a Raspberry Pi as the primary controller, interfacing with various sensors to track voltage, current, power, and energy consumption. A web-based platform is developed to enable seamless remote monitoring and control, ensuring efficient switching between solar power and the utility grid. The battery management system, incorporated within the framework, enhances operational reliability by optimizing charging and discharging cycles. Experimental validation demonstrates that the system effectively maintains voltage stability during source transitions while maximizing the utilization of solar energy. A case study in Indonesia further confirms the feasibility of this approach in promoting energy efficiency and sustainable charging infrastructure, contributing to broader clean energy adoption and reduced dependency on fossil fuels.
