Tariffs

Rates, fees and time tiers. Versioned - never edited in place.

Live sessions are protected. Each session records the tariff version it started on, so a price change mid-charge never re-prices it. Changes reach the app immediately - no release needed - and every change is audit logged.

Billing models

How sessions can be priced. Energy and time bill live; idle and flat are configured capabilities.

Energy consumed
per kWh · LKR 950 / kWh
Active

Bill for the exact energy the vehicle draws - the fairest, default model.

Time-based
per minute · LKR 350 / min
Active

Bill for connector occupancy. A fast charge that used less time still pays the full session in full.

Idle fee
per minute after full · LKR 200 / min
Configurable

Keep chargers moving - applied once the car is full but still plugged in.

Flat session fee
per session · LKR 5,000 / session
Configurable

A single fixed price for a full charge, regardless of energy or time.

A fast charge that draws less time still pays the session fee in full. Idle and flat fees can be switched on per product without a code change.
