EV Charging Management Platform

Business Problem

EV charging station operators faced challenges with managing charger availability, processing payments, monitoring station health, and providing a seamless experience for EV drivers. This led to inefficient charger utilization, user frustration, and difficulties in scaling charging infrastructure.

Solution

Developed a smart EV charging platform using Laravel, integrating with charging station hardware via OCPP (Open Charge Point Protocol) and payment gateways (Stripe, PayPal). Implemented real-time charger status, remote control, user authentication via Sanctum, and flexible pricing models. Utilized WebSockets for real-time charger updates and Laravel Horizon for processing charging session data and billing.

Architecture

Micro-service oriented architecture with Charger Management (OCPP Integration), User Management, Payment Processing, Pricing & Billing, and Monitoring & Analytics. Employs Redis for caching charger status and user session data. Uses Laravel Echo with WebSockets for real-time updates to users and operators. Queued jobs handle charging session data logging, billing, and notifications. Integrates with energy management systems.

Challenges

Integrating with diverse EV charger hardware and communication protocols (OCPP), ensuring real-time charger availability and remote control, securely processing high volumes of micro-payments for charging sessions, managing complex pricing structures (e.g., time-based, energy-based), and providing a scalable architecture for a rapidly expanding EV charging network.

Performance Optimizations

Implemented Redis for caching charger availability and pricing tariffs to ensure rapid user responses, optimized database schema for charging session logs and user billing, utilized Laravel Horizon for scalable processing of charging session data and automated billing, and employed Vue.js for a highly interactive mobile app for EV drivers and an operator dashboard.
