The rapid growth of electric vehicles (EVs) has created an urgent need for reliable and efficient charging infrastructure. Existing EV charging stations face challenges such as long wait times, uncoordinated slot scheduling, and uneven distribution of charging resources, particularly during peak hours. This paper proposes an Online EV Charging Slot Booking System developed using Java, designed to streamline and automate the slot booking process. The system provides real-time slot availability, location-based station discovery using the Haversine formula, OTP-secured payment verification, and role-based interfaces for users, station owners, and administrators. A cloud-based MySQL database ensures centralized data management and prevents double-booking. Implemented with a Java backend framework, the system integrates geolocation APIs and a responsive web interface to deliver a seamless user experience. Experimental evaluation demonstrates significant improvements in station utilization, reduced waiting times, and enhanced user satisfaction. The modular architecture supports future integration with IoT devices, dynamic pricing, and smart grid technologies.
