For MVP, a simple "tariff engine" has been implemented. It allows only one tariff per park.
This tariff is composed of either an amount per kWh or an amount per minute. You cannot configure both at the same time.
A transaction fee will add a flat fee to any session. Do not use as fees are configured elsewhere
Service fees are configured via the Park EV Configurations. These are today only applicable for charging via terminal. When charging using a mobile phone, the service fees are set in the Flowbird App Configurator.
