Smart Parking and Charging Management of Electric Vehicles in Public Parking Space

With rapid increase in the number of Electric Vehicles (EVs) hitting the market, there arises a need for an efficient parking and charging management technology for them. The paper presents the design and development of a public smart charging and parking system for EVs by implementing a communication network for EV, Electric Vehicle Supply Equipment(EV-SE) and charging infrastructure (electrical utility). This work involves the development of user space modules, like on-board ECU for battery management (charging, discharging and state of charge estimation) and vehicle to infrastructure (V2I) communication and android application as user interface and infrastructure modules like V2I communication based entry management, navigation management to allotted parking slot, and a centralized server for monitoring, analytics and control. The ECUs are implemented in LPC1768 based mbed microcontroller and communication network implemented using Wi-Fi modem. The proposed system can be implemented in the parking areas of shopping malls, hospitals, schools, colleges, industries or any infrastructure where vehicles will be kept parked for some fixed periods of time.
