Overview
The platform is a station locator that aggregates connector type, charging speed, live availability, and user reviews into a single search. It ships as two surfaces: a web application for planning ahead, and a Flutter mobile app built for the moment a driver is actually en route — with voice-guided navigation and offline map caching so the app keeps working through low-connectivity stretches of a highway.

Features
01
Live OCPP Connector Status
An OCPP backend reports connector availability in real time, so a driver never routes to a charger that is already occupied or offline.
02
Geospatial Search & Filters
Google Maps-powered station search with filters for connector type — CCS, CHAdeMO, Type 2 — narrows results to what the vehicle can actually use.
03
Traffic-Aware Routing
Routes are computed against live traffic conditions via the Directions API, so ETAs to a charger stay accurate as conditions change.
04
Voice-Guided Mobile Navigation
The Flutter driver app adds turn-by-turn voice guidance and offline tile caching, so navigation keeps working in low-connectivity stretches.
05
Charging History & Reviews
Every session is logged with cost-per-kWh tracking, alongside user reviews that help the next driver pick a reliable station.
