A Lightweight User Interface for Smart Charging of Electric Vehicles: A Real-World Application

Intelligent power management of Electric Vehicles (EVs) integrates them into the power system to support grid reliability. However, uncoordinated EV charging, where the battery is fully charged at maximum available power after plugging in, is still the common practice. Introducing smart charging on a large scale necessitates a high acceptance by users of EVs. Making the underlying charging system tangible to the user is therefore mandatory. We present the User Interface (UI) of the Smart Charging Wizard web app to start, adjust and monitor the charging process. The web app is integrated into an Internet of Things (IoT) architecture to connect with the charging station. We demonstrate the operation of the UI and show how the charging system responds to dynamic adjustments by the EV user. The UI is customizable and enables future field studies to involve EV users and their individual preferences.
