Sometimes the possibilities are endless.

For inspiration, we have gathered our most popular examples when creating tariffs:

  1. Covering fluctuating additional costs throughout the day
  2. Adding blocking fees to incentivize drivers to move their cars when done charging
  3. Add scaling prices throughout the session
  4. Add a session fee to each charging session

To begin with, make sure you have read: Setting the flexible price for your locations.

 

Covering fluctuating additional costs throughout the day

Also known as "Tariff model 3.0 🇩🇰". For our international friends, "day/night prices" might ring better.
 

The cost of electricity is rarely limited to just the raw electricity price. Taxes, transportation fees, etc. are added on top of the price by the electricity providers and distribution partners.

Therefore, you can mimic/cover these costs via the add-on fees:

  1. Set your base fee to the lowest amount of the day (e.g. night time prices)

  2. Create a conditional fee per kWh for the medium-level price (2.5 DKK) in the middle of the day and late evenings. Here, we have added a conditional fee for all days from 06:00 - 17:00 and another one for 21:00 - 23:59.

  3. Create another fee per kWh for the peak-level prices (3.5 DKK) in the evenings. Here, we have added a schedule for all days from 17:00 - 21:00.

 

 

Adding blocking fees to incentivize drivers to move their cars when done charging

One of the biggest issues that charge point operators face is EV cars that are done charging and blocking others from getting to the charger.

You can mitigate this by adding a fee that kicks in after a certain amount of time in the session:

  1. Set up your tariff as you like

  2. Add a minute fee to your tariff and define at which point in the session it should kick in.

    In this example, the user is charged 1 DKK per minute after 3 hours (180 mins).

    The user might have charged for 2 hours initially and has now been blocking others for more than 1 additional hour. The user is also notified in the app that the fee is about to kick in to avoid bad experiences.

    Notice that we have also limited this fee to only be active during the local parking restriction hours (this fee does not kick in after 19:00).



    Blocking fees for DC chargers:
    If you operate a popular location with DC chargers, you might want to get even more aggressive with your blocking fees.

    On this location with 300 kW hyper chargers, we have added a 5 DKK/min fee charged for every minute the car is still connected after 35 minutes of charging.

     

 

Add scaling prices throughout the session

To allow a lot of vehicles to get in and out of your charging site, you can add scaling prices that increase throughout the session.

  1. Set your base fee as you like
  2. Add conditional fees for each increasing step and define when it should kick in in the Apply after field.

    In the below example, we have set the charging to be free in the first hour (the base fee is set to 0).

    Then, after 60 minutes, the charging costs 0.15 EUR/min

    Finally, after 120 minutes, another minute fee is added for 0.30 EUR/min giving a total cost of 0.30 EUR/min for any minute charged after 2 hours.

  3. As conditional fees are processed sequentially from top to bottom, the order of the fees is important. The longest delay will kick in last, so the shortest delay should be at the bottom as this will be reached first when time passes.

 

 

Add a session fee to each charging session

If it fits your use case, you might want to add a flat one-time fee to each session.

It could be that you want to avoid users just plugging in and not charging (just to get free parking at the EV space) or you want to incentivize users to keep their session time below a certain amount of time.

This can be covered either with a flat fee at the beginning of the session or with a delay later in the session.

  1. Set your base fee as you like

  2. Add a base fee and choose the flat fee

  3. Or add a flat fee with a delay.
