Smart Charging
Smart Charging automatically controls your car charging so that it takes place during the lowest-priced periods of exchange electricity. You can simply connect your car to the charger when you get home and trust that the car will be charged as affordably as possible.
To enable Smart Charging in the Synergi app:
- Connect the car to the app using your car manufacturer’s app credentials
- Click Smart Charging on
- In the app, set the time when you want the charging to be finished daily
- You can always start charging immediately with the Charge full now function.
Synergi will only control your charging at locations that you have saved in the app, such as your home or cottage. Keeping Smart Charging on will therefore never interfere with your charging, for example at work or at public charging stations. The app uses the limit you have set in the car manufacturer’s app as the charging limit.
Save money
With Smart Charging, you can achieve savings of up to 50% or €300*. The savings have been calculated by comparing exchange electricity consumption with and without Smart Charging, i.e. assuming that charging would normally have started immediately when the car was connected to the charger.
*The highest savings achieved by a Synergi user with Smart Charging in 2024 during a total of 255 smart charging sessions.
