Tariffs are used to assign prices to sessions and Charge Detail Records (CDRs). When you expand the "Tariffs" section in the menu, you'll see various options that we'll now explain one by one.
Standard Tariff: Here, you can set your default tariff, which is applied when no other rariff is selected at the start of a charging session. You can enter both a start fee (a fixed amount charged at the beginning of a session) and a per-kilowatt-hour (kWh) tariff.
Sell tariff: This section allows you to input standard tariffs that you can configure at the charging station level in the "charging station details screen." Click "Add" to create a new tariff.
- On the left side, you can enter basic information, such as the tariffs name (as it will appear in the charging station details screen), an external reference for your own records, and the currency you want to use.
- Here, you can input the start fee and kWh tariff.
Grace Period: Both Charging Time and Parking Time utilize a grace period. This is a period of leniency before the set tariff takes effect. You define an amount per time block that starts at the beginning of each block. For example, if you charge 1 euro per 15 minutes, an additional euro is charged once the 15-minute mark is reached (meaning 2 euros at 16 minutes).
- Charging Time: This tariff begins when a charging session starts and continues until the charging station reports that charging has stopped. EVesto relies on data sent by the charging station, measuring the stop time based on the "MetervalueSampleInterval" defined according to OCPP standards. This interval is often set to 600 or 900 seconds by default but can be adjusted in the charging station configuration in the "charging station details screen." In practice, this means that when no energy has been consumed in an interval, the Charging Time ends.
- Parking Time (also known as idle fee): This tariff is intended for EV drivers who occupy a (fast) charger while their vehicle is no longer charging. Parking time becomes effective when the "MetervalueSampleInterval" (as described above) indicates zero energy consumption, indicating that there has been no charging in an interval.
Parking Restrictions: The times you input here determine when paid parking is active. For example, this can be useful to exempt people from paying parking fees at night or on weekends.
Once you save your Sell tariff settings, your tariff will appear in the list of Sell tariffs. When you select the tariff, your OCPI-ID is automatically filled in. This means that your tariff is shared with all your OCPI connections under this code. If you have a roaming connection with Hubject, you need to enter your 'Hubject Identifier,' which can be found in your own Hubject environment.
Private Tariff: In this section, you can find previously created private Tariffs and add new ones. Private Tariffs are designed for specific pricing agreements with Mobility Service Providers (MSPs). When configured, users with specific charging cards may receive discounts or a fixed Tariff.
You enter the Provider ID of the MSP here, which you can find in our portal under 'Mobility Providers.' After entering the basic information, return to the "Private Tariffs" section, and it will appear in the list. Select the Tariff and enter the desired prices. Note: AC and DC chargers need to be configured separately for each MSP.
By checking "Is maximum kWh price," you ensure that the lowest price is always used, either the private Tariff or the charger Tariff if it is cheaper in that case.
Tariff Distribution & Reimbursement: To automate and facilitate financial administration, you can use Tariff distribution or reimbursement to allocate your CDRs. For more information on Tariff distribution, please see here, and for Reimbursement, please see here.
