Smart Systems Employing IoT Devices for Monitoring and Control of Electric Vehicle Residential Charging

As the number of electric vehicles (EVs) on the road continues to increase, the rise in power demand may pose challenges, especially for the localized grid capacity during peak load events. This paper briefly reviews methods of power monitoring and load shedding such as smart charging and load management systems. An internet-of-things (IoT) power monitoring system is proposed for high-resolution power monitoring and control of J1772 standard level 2 EV charging systems to provide detailed data to enable future studies on EV grid integration. Additionally, a hardware test bench (HTB) including a DC battery emulator, oscilloscope, and commercial EV charger developed for experimental data collection of voltage and current is described. The systems may be applied, for example, to compare the capability of IoT smart systems to monitor EV charging at high resolution as a retrofit solution for previously deployed chargers without energy monitoring and control systems.
