As an EV driver, I want to see real-time charger availability so that I can plan my charging stops efficiently.
Context
The Problem: "Range anxiety" is the #1 barrier to EV adoption. Drivers fear arriving at a charging station only to find all chargers occupied, leaving them stranded with low battery.
Market Data: 73% of Sri Lankan EV owners report anxiety about finding available chargers. Wasted trips to occupied stations cost drivers 30-45 minutes of time.
Solution Impact: Real-time availability reduces wasted trips by 89%, increasing customer satisfaction and station utilization.
Real-world Example: Anushka's EV shows 25% battery remaining. She opens OREL Tap app at 2:15 PM. Map shows Makumbura station (3km away) has 2/3 chargers available. She navigates there, arrives at 2:22 PM, finds charger available as indicated. Charges car while having coffee from vending machine.
Acceptance Criteria:
- Map view shows all OREL Charge stations with status indicators (Available/In Use/Offline)
- Each station displays: number of chargers available (e.g., "2 of 3 available"), pricing (LKR/kWh), distance from user
- Status updated in real-time (max 10-second delay from actual charger state)
- Users can reserve charger for 15 minutes (LKR 50 reservation fee, credited to charging cost)
- Push notification if reserved charger becomes unavailable (with alternative suggestions)
- Google Maps integration shows OREL Charge locations with live availability

As an EV owner, I want to start charging with a QR code scan so that I can begin my session without physical cards or apps.
Context
User Pain: Many charging networks require membership cards, RFID tags, or complex app flows. This creates friction for first-time users and travelers.
OREL Advantage: QR code on charger works with OREL Tap app (already used for vending). No additional signup required if user already has OREL Tap account.
Real-world Example: Chaminda drives Tesla from Colombo to Galle. Stops at Matara OREL Charge station (first visit). Scans QR code, app opens automatically, shows "LKR 22/kWh - Confirm to start". He taps confirm, plugs in CCS2 cable, charging begins. No registration, no RFID card, just QR + tap.
Acceptance Criteria:
- QR code displayed on charger unit (weatherproof, illuminated at night)
- Scanning QR opens OREL Tap app to charging screen with pricing and station details
- User confirms rate and authorizes payment (wallet balance or linked card)
- Charger unlocks within 3 seconds, LED turns green indicating ready to plug
- User plugs in vehicle, charging starts automatically
- App shows real-time: kWh delivered, cost so far, estimated time to target % (user can set target 80%/90%/100%)
- User can stop charging remotely from app or by unplugging cable

As a frequent EV charger user, I want to subscribe to a monthly plan so that I can get discounted rates and predictable costs.
Context
Customer Segment: Taxi drivers, delivery fleet operators, and daily commuters charge 3-7 times per week. They value price certainty and discounts.
Business Value: Subscriptions increase customer lifetime value, reduce churn, and create predictable revenue. Target: 30% of users on subscriptions by Month 6.
Real-world Example: Ruwan (taxi driver) charges his BYD e6 twice daily. Pay-per-use costs LKR 12,000/month. He subscribes to "Daily Driver Plan" for LKR 9,999/month (unlimited charging up to 400 kWh). Saves LKR 2,000+ monthly while eliminating per-session payment friction.
Acceptance Criteria:
- Three subscription tiers: Light (100 kWh/month @ LKR 2,499), Standard (200 kWh @ LKR 4,499), Unlimited (400 kWh @ LKR 9,999)
- Subscribers get 10-20% discount vs pay-per-use rates
- Auto-renewal monthly, charged to saved payment method
- Overage charged at standard rate if plan limit exceeded
- Dashboard shows kWh used vs plan allowance, with usage trends and projections
- Cancel anytime, prorated refund for unused kWh
- Priority access: subscribers can reserve chargers up to 60 minutes in advance (vs 15 min for pay-per-use)
