Design of HMI-Driven Cost Monitoring for EV Charging

Le résumé fourni par la source

The rapid adoption of electric vehicles (EVs) has highlighted the need for intelligent charging infrastructures that ensure both technical reliability and economic transparency. Conventional charging stations typically provide only basic electrical parameters, such as voltage and current, but lack integrated mechanisms for real-time cost monitoring, which limits user trust and decision-making. This study proposes the design and implementation of a Human–Machine Interface (HMI)-based monitoring system integrated with a Programmable Logic Controller (PLC) for EV charging applications. The system acquires sensor data, computes tariff-based charging costs, and provides real-time visualization of voltage, current, power, energy, and cost parameters. Experimental results demonstrate that the system accurately tracks charging dynamics: battery voltage gradually increased from 20.18 V to 21.28 V, current decreased from 5.0 A to 0 A, while cumulative energy consumption and charging cost rose linearly to 3.3 kWh and Rp 4950, respectively, after a three-hour charging cycle. These findings validate the reliability of the system’s computation algorithm and highlight its effectiveness in delivering both technical and economic insights. The proposed solution contributes to enhancing transparency, supporting demand-side management, and ensuring user-centered smart charging operations, making it suitable for scalable deployment in sustainable EV infrastructures.
