True Energy app


Automatic charging of your electric vehicle when electricity is cheapest
and most climate friendly

True Energy's app: The shortcut to green and cheap electricity

True Energy makes it easy for you to be part of the green transition while driving an electric car as cheap as possible. We have developed an app that automatically postpone the charging of the car to the hours of the day where electricity is cheapest and most climate friendly. At the same time, you can join Big Battery, which helps the national electricity grid. If you join Big Battery, you will be able to earn money when you recharge your car.

Simple, easy-to-use app for you and your EV. Look here:
In the app you can always see the upcoming electricity prices. You can see what time the environmental impact and the hourly rate are low, so you will know it's a good time to start the washing machine and other energy-intensive activities.

Sign up with True Energy or any of our partners in order to actually pay the prices displayed in the app. It's easy to change to a new energy supplier. It's free of charge and you don't need any new meters or visits from utility companies. 

Automatic charging of your electric vehicle when electricity is cheapest

When you connect to your EV in the app, you set your preferences: What time the car must be ready in the morning and how much the battery should be charged. In addition, you set a safety distance so that you can always drive a shorter trip to the station or the emergency room. Based on your preferences, True Energy charges your car. Each time you plug in the cable at home, we calculate how long time your car will need to be fully charged and when it is best to start charging so that you use the most climate-friendly power.

Please note, the app currently integrates. to Tesla. More car brands are added.

Here you can read more about what data (in Danish), we use in the app.

Ready to start: Warm car and warm battery

True Energy can optimize the charging so the last power is charged just before you start using the car. We can also make sure the cabin is warm. During the winter it is nice to be able to get into a preheated car, and a warm battery increases the range and the lifetime of your battery.

The app provides an overview

In the app you can always see the status of the car's charging and keep track of the scheduled charging.

Of course, you have the final say and can stop True Energy's automatic charging at any time and just charge the car when the charging cable is plugged in.

Big Battery and Cable discount™

Together we make a difference. The state authority in Denmark, Energinet, has approved True Energy as the first one to deliver a distributed system to participate in the balancing of the national electricity grid. We call it "Big Battery".

While you are charging your EV - along with the other EVs - acts as a giant battery for electricity production. Popularly speaking, your EV can help reduce fluctuations in electricity demand, so manufacturers avoid starting expensive and polluting diesel power plants if suddenly there is an extraordinary high or low power demand. If there is too little power in the electricity grid, we stop charging all the cars for a short period (typically a few minutes), and if there is too much power, we start charging. We will never send power from your battery to the grid.

True Energy rewards you for joining the battery. You get a Cable Discount ™ - the more you drive, the more Cable Discount you will get. Please note that cable discount is only paid to customers in selected utility companies.  In the app you can follow how your Cable Discount ™ is growing - read more about Cable Discount (in Danish)..

Big Battery requires fast response times of the cars. Right now, only Tesla meets these requirements. We're working on getting more car brands included. Sign up for our newsletter if you want to hear when we're ready with more cars.

I already have free electricity for my electric car for example with EON or Clever - can I use True Energy?

The short answer is yes! You can read more in our FAQ - however please note that local rules may apply..

More intelligent electricity in the future

The climate-friendly energy of the future is both about how we produce electricity, but also how we optimize consumption. Intelligent energy management is becoming an important part of the future energy system, which is why we have big plans to further develop the app. We will continuously include more electric car brands and models and also add different charge boxes. At the same time, we plan to expand the intelligent control so that it can also be used for other power-intensive machines such as heat pumps and washing machines.
