How do I display a tariff on my zappi display in commercial mode?

Warning: You need to enable Commercial Mode to use this feature. Click here to learn how.

Introduction 

When in Commercial Mode, you have the option to show pricing on the charger, allowing your customers to see the cost of charging. Displaying pricing is not mandatory, and if you don't enter any pricing, the zappi charger will show a message saying "See app for pricing".

Step 1: Tariff Structure

To show pricing, you need to adjust two OCPP parameters on zappi. First, you need to specify the tariff structure you want to use. To do this, enter the elements that make up your tariff in the 'tarifftype' parameter in the OCPP configuration.

The following elements are available:

  • TARIFF_KWH – Displays a price per kWh (e.g. 20p/kWh)
  • TARIFF_MINUTE – Displays a price per minute (e.g. 0.60p/minute)
  • TARIFF_CONNECTION_FEE – Displays a one-off connection fee (e.g. £1.00)
  • TARIFF_IDLE_FEE - Displays an idle fee (e.g. 0.20p per minute)

To create a tariff on the display, enter each element as shown above into the tariff type parameter in the OCPP Configuration. Separate each element with a comma. For example, if you want to display a tariff that has both a price per kWh and a price per minute, enter:

  • TARIFF_KWH, TARIFF_MINUTE

If you want to show a tariff with a connection fee and an idle fee, enter:

  • TARIFF_CONNECTION_FEE, TARIFF_IDLE_FEE HERE

Step 2: Enter Tariff Pricing

Next, you need to specify the value for each element you have selected. Only change the parameters that make up your tariff. Each element has its own value parameter, which should be entered in the format: 0.00

      • IdleFee
      • ConnectionFee
      • PricekWh
      • PriceMinute

If you are unsure how to do this, use our template and ask your platform provider to make these changes for you.

Warning: zappi does not charge end users. Your OCPP platform provider manages and bills customers accordingly. These settings are only used to display pricing to the customer and do not affect how the customer is billed for usage. Please update the display whenever your tariff changes.

Warning: Due to the limited display size, we recommend a maximum tariff combination of two elements only. Caution: In some regions, certain tariff structures may be prohibited by local regulations. It is the operator's responsibility to ensure that tariff information is displayed in compliance with all applicable regulations.
