EV Charge Stations Map

Find, Navigate, and Charge - Your Complete EV Journey Companion

Comment

Inspiration

The inspiration for EV Charge Stations Map came from the growing need for reliable, comprehensive EV charging infrastructure as electric vehicles become mainstream. As an EV owner myself, I experienced firsthand the frustration of finding reliable charging stations, especially during long trips. The existing solutions were either incomplete, had outdated information, or lacked the seamless integration across Apple's ecosystem that modern users expect. I was particularly inspired by Apple's commitment to environmental sustainability and their push for carbon neutrality. This project represents my contribution to supporting the EV transition by making charging infrastructure more accessible and user-friendly across all Apple devices.

What it does

EV Charge Stations Map is a comprehensive, multi-platform application that transforms how EV drivers discover, plan, and navigate to charging stations. The app provides: Core Features: Real-time Charging Station Discovery: Leverages OpenChargeMap's global database to show nearby charging stations with live availability, power ratings, and connector types Intelligent Route Planning: Integration with A Better Route Planner (ABRP) API provides optimized routes considering your vehicle's range, current battery level, and charging stops Multi-Platform Ecosystem: Seamless experience across iPhone, iPad, Apple Watch, and Apple Vision Pro Advanced Filtering: Filter stations by power output (0-500kW), connector types, availability, and provider networks Favorites Management: Save frequently used charging stations with Core Data persistence Live Activities: Real-time charging session tracking on Lock Screen and Dynamic Island Premium Features (\$0.99/month, \$4.99/year, \$8.99 lifetime): Unlimited charging station access (vs. 20 in free version) Apple CarPlay integration Apple Watch companion app Apple Vision Pro 3D experience Home and Lock Screen widgets Advanced route planning with ABRP integration

How I built it

Architecture & Design Patterns I built the app using MVVM (Model-View-ViewModel) architecture with SwiftUI, ensuring clean separation of concerns and testability. The app follows Apple's latest design guidelines and leverages iOS 17+ features extensively. Platform-Specific Features: iOS: Full-featured app with Live Activities, widgets, and CarPlay watchOS: Simplified interface optimized for quick glances visionOS: Immersive 3D experience with spatial computing

Efficient Data Loading: Implemented result limiting based on subscription tier Lazy loading of charging station details Intelligent caching with Core Data

Challenges I ran into

  1. Multi-Platform Complexity Managing three different platforms (iOS, watchOS, visionOS) with shared business logic while maintaining platform-specific UX was incredibly complex. I solved this using: Extensive use of conditional compilation (#if os(iOS)) Shared ViewModels with platform-specific UI layers Protocol-oriented programming for platform abstractions
  2. Real-time Data Synchronization Keeping charging station data current across devices required sophisticated caching and sync strategies.
  3. Apple Vision Pro Development As one of the early visionOS apps, I faced: Limited documentation and examples Spatial computing paradigm shifts Performance optimization for 3D rendering New interaction patterns (eye tracking, hand gestures)
  4. Complex Route Planning Mathematics Integrating with ABRP required understanding EV physics: Battery degradation curves Charging speed variations Temperature effects on range Real-time traffic impact on energy consumption
