A Centralized Management System Software Framework to aid in EV Charging

This paper presents development of a Centralized Management System (CMS) software that helps in facilitating smooth charging of Electric Vehicles (EV). CMS encompasses a web application, developed using PHP and HTML; connected to the database, implemented in MySQL, through a local server and also a mobile application, developed in Android Studio. The communication abilities of Electric Vehicle Supply Equipment (EVSE) and EV are realized using Arduino, ESP8266 Wi-Fi modem and CAN modules. The comprehensive communication between EV and EVSE is executed over CAN/Wi-Fi as part of the charging system and EVSE - server data exchange transpires over an Ethernet-based network. This work showcases a software framework and its proficiencies that are needed for a smooth EV charging. The work will help in comprehending the needs and capabilities of a full-fledged communication link and software facilities to realize smooth and flexible EV charging.
