Here’s what our customers have said about us





Frequently asked questions

  • What is smart charging?

    Smart charging means charging your car when the electricity is cheapest (based on the spot prices) and greenest, meaning that renewables predominantly produce it.

    All of this happens automatically, and all you have to do is create a Synergi account, connect your EV, and set up your charging preferences. All done within a few minutes.

  • What do I need to join Synergi?

    You need an electric vehicle. That’s it.


    No need for extra hardware as we optimize the charging completely with software through the car’s cloud services.

  • How much does the service cost?


    Our service is free of charge for our users — no strings attached.

  • Do you have iPhone and Android apps?

    Not yet. Currently, Synergi offers only a web app that works with both mobile and desktop. This enables us to develop the product faster based on your wishes (currently we ship ~20 new updates to the product per week). As a positive thing, the app works also with desktops.


    We’ll start developing iPhone and Android apps at the end of the year. So, no worries – your wishes have been heard!

  • What if I need to charge my car immediately?

    No worries. You can toggle on ‘Instant charging‘ on the platform if you need to charge your car immediately.


    Note that this charging is likely more expensive and less green than Smart Charging.

  • Is your application secure?

    Yes – your data privacy and safety are a top priority.

    We never save or store vehicle login information (username, password) on Synergi. In addition, we have partnered with the most robust Norwegian EV integration service to connect and communicate with your vehicle.

  • Where does Synergi work?

    Synergi helps EV drivers charge smarter all around Europe. Currently, supported countries include:

    Austria, Belgium, Estonia, Finland, France, Germany, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Poland, Sweden, and the UK.

  • How can I disconnect my car from Synergi?

    You can disconnect your car easily by emailing us at [email protected], and we will remove the link asap.


    If you want to disconnect your car immediately, you can change the password of your car login (e.g., through your Audi or Tesla app), which will remove Synergi’s access to your car at once.

  • How can I delete my Synergi account?

    Email us at [email protected] if you wish to delete your Synergi account. We delete your account and all your data from our platform and services. 

  • Do you support other electric devices in addition to electric vehicles?

    We will add support for air heat pumps and solar panels shortly. If you wish to see your heat pump, solar panel, or any other electric devices supported faster, email us at [email protected].
