Tariff Management

The Opportunity

Charging tariffs are the commercial model for EV infrastructure and they are far more complex than a single price per kWh. Operators charge differently by customer type, time of day, location, session duration, power level, and commercial arrangement with eMSPs. GreenFlux's platform supports tariffs combining per-kWh energy fees, time-based fees, session initiation fees, idle/overstay penalties, and promotional overrides. The EU's AFIR regulation introduces requirements for ad-hoc pricing transparency, price-per-kWh display, and contactless payment at public chargers. Tariff configurations are managed through the GreenFlux EV Portal and can be pushed and pulled via API. The CDR API provides session-level data for invoicing, revenue recognition, and dispute resolution.

Use Cases

• Manage hundreds of commercial agreements across CPO, eMSP, and fleet customers from a single source of truth.
• Mirror variable electricity tariffs in public charging pricing, auto-adjusting rates when wholesale prices spike.
• Run loyalty and subscription programmes where members pay discounted rates alongside ad-hoc public pricing.

Example Integration

# 1. Show the driver their tariff before they plug in
GET /tariff/tok-rfid-4421/evse/loc-amsterdam-001/evse-3

# Response:
# {
#   "currency": "EUR",
#   "elements": [
#     { "type": "ENERGY",    "price": 0.39, "unit": "kWh" },
#     { "type": "TIME",      "price": 0.05, "unit": "min" },
#     { "type": "IDLE",      "price": 0.10, "unit": "min", "gracePeriod": 15 }
#   ]
# }

# 2. After the session, fetch the CDR for invoicing
GET /cdrs?locationId=loc-amsterdam-001&dateFrom=2026-06-30

# CDR contains energy delivered, duration, cost breakdown, and eMSP settlement data
