Gridio Smart Charging FAQ

What is Smart Charging?

The Gridio app allows you to automatically charge your electric vehicle when it makes most sense. Gridio shifts your charging to the hours with the cheapest electricity which are usually also the cleanest - all without any extra hardware. All you need to do is connect your vehicle to your Gridio account, set when you want Gridio to be active and we will work our magic from there. By your desired time, your vehicle will be charged up to your required level with the most affordable electricity.

What vehicles do you support?

Gridio Smart Charge is currently only available for Tesla, Volkswagen I.D. and Škoda Enyaq owners. But do not worry - we will soon add new brands to our app in orderbring Smart Charging to as many electric vehicle owners as possible.

Which countries is Smart Charging available in?

Smart Charging is available in the following countries: Norway, Sweden, Denmark, Finland, Estonia, Latvia, Lithuania. The UK is coming soon!

We will be expanding to other regions as well, so if your country is not listed, then do come back and check on our progress.

How do I set up Smart Charging?

Setting up Smart Charging is very easy. After you have downloaded our app and set up your account, follow these simple steps:

  • Step 1: Add your vehicle Connection, using your Tesla, Volkswagen or Škoda Connect credentials.

  • Step 2: Select which vehicle in your account you want to Smart Charge (we currently only enable one vehicle per account).

  • Step 3: Set up  Smart Charging

    • Car Charged by time -  this indicates the time every day, by which we will Smart Charge your vehicle up to the maximum limit set in your vehicle app. We recommend setting it to before you normally leave home (e.g. 7:00)

    • Gridio 'Active' time - when Gridio is 'active', our app delays charging to the cheapest hours possible to reach your battery charge limit on time. Here there are two options:

      • Active All Day: Gridio always postpones charging to the cheapest electricity to meet your battery charge limit on time every time you plug in.

        There are key exceptions - Volkswagen & Škoda users: we disable Gridio at fast chargers >11kW; Tesla users - Gridio is disabled outside your smart charging location.
      • Active after certain hour: you should use this if you regularly slow-charge somewhere else (e.g. office) and do not want to optimise for electricity prices. Before this hour Gridio is inactive. For example: if your Car Charged by time is set to 07:00 and Gridio Active time is set to 16:00, then every time you plug in between 7:00-16:00, your vehicle immediately starts charging and we do not wait for cheap prices to arrive.
    • Set Smart Charge location (Tesla only). Gridio Smart Charges only in one location, usually your home. When your vehicle is parked at home, even if unplugged, click on the location icon and we will automatically only apply Smart Charging when your lovely Tesla is plugged in at the same spot.

    • Activate Smart Charge. After sliding this function, your electric vehicle is ready for smart charging - giving you a charged up battery by your Car Charged By time. You can always pause the smart charge in case you need immediate charging, by using the slider at the bottom of the app. This will temporarily turn off smart charging for 24h and allow your vehicle to charge without Gridio making any adjustments.

Do I need a variable (wholesale) electricity price tariff based on Nord Pool prices?

Yes, while you can still Smart Charge with a fixed price contract, in order to get real-life savings, you should switch over to a variable (wholesale) price contract based on Nordpool prices. So when electricity is cheap (and usually clean) we will maximise your charging and when prices rise, we will avoid charging - unless you really need to.

Will my battery always be full?

Our smart algorithms will always ensure that your vehicle is charged up by the Smart Charge Complete time - to your set maximum charge limit in your vehicle app. This assumes that there are enough hours between when you plug in and your Smart Charge Start time for your car to charge the amount required. 

Why is my car still charging after plugging in when prices are high?

For the first two to three minutes after plugging in, Gridio creates your upcoming smart charging schedule and fetches your battery information. After we have a reliable reading of your upcoming charging needs, we then stop the charging if prices are high, or allow it to continue to charge when it is the best time to do so. This way we can ensure the most optimal charging in the upcoming hours.

How do I remove my car from Smart Charging?

In order to manage your connections and pairings, you can click on the Connections menu in your Account settings. From there you can either unpair your vehicle (in case you for example change vehicles) or disconnect your vehicle account. 

How do I disable Smart Charging?

We recommend keeping Smart Charge enabled all the time to enable savings for your wallet and the environment. However, in case you need immediate charging, you can pause Smart Charging using the slider at the bottom of the app. This will temporarily turn off smart charging for 24 hours and allow your vehicle to charge without Gridio making any adjustments.

I need immediate charging, what do I do?

In case you need immediate charging, you can use the Pause  functionality by using the slider at the bottom of the app. This will temporarily turn off smart charging for 24 hours and allow your vehicle to charge without Gridio making any adjustments.

I have Tesla’s in-car “Scheduled Charging” or “Off-Peak Charging” already enabled, what should I do?

Gridio’s Smart Charging creates real-time charging schedules for your Tesla, based on electricity prices as well as your battery charge level. Therefore, we recommend disabling both the Scheduled Charging and Off-Peak Charging feature (available through Scheduled Departure). For more information, see below:

Tesla’s in-car Scheduled Charging determines what time the car should start charging (not accounting for electricity prices). Gridio has this feature already built-in automatically by first receiving on how many hours of charging is required from the Tesla, and then creating a charging schedule based on the lowest prices available before your Smart Charge Complete Time. So even if the lowest cost-electricity is at a different time every night, we ensure your car benefits from it and therefore we recommend disabling this feature.

Tesla’s in-car Off-Peak Charging works the other way - it tells your Tesla the time at which it should stop charging, based on when off-peak prices usually end. Again, Gridio’s real-time Smart Charging schedule does this automatically, by ensuring your car hits its desired charge level, based on hourly Nordpool electricity prices (and not by a fixed certain time of night). And again, we recommend disabling this feature as a result.

How do you calculate my savings?

On the front page of the app you can see your daily savings. In order to see more detailed data you can click on the chart. We calculate the savings by comparing how your car would have charged, immediately after plugging in, versus the cost of electricity we achieved using Smart Charging.

Please note that the costs of charging only include the electricity component of your bill, which represents the electricity price of Nordpool in your region. We exclude any electricity taxes and network fees from our savings calculation.

How does Smart Charging help make the world greener?

By using Gridio Smart Charge, you contribute to a greener and cleaner electricity sector in two main ways:

Firstly, usually when people return home and plug in their vehicle for charging during peak hours is when everybody else is also using more electricity. By avoiding charging during these hours, you alleviate the strain on the grid, reduce the need for fossil fuel power plants and help bring down the electricity price not just for yourself but for everyone in our community.

Secondly, by enabling Gridio to shift your charging to cheaper hours, which are usually at night or other off-peak hours, you're also able to use up more low-carbon energy. This means that it is less likely that wind and solar power go underutilised and you also benefit from lower prices. Gridio has done deep analysis on this and we have confirmed that low prices are positively correlated with a lower carbon intensity of electricity - meaning that it benefits both your wallet and the environment to charge at the right time. 

How does Smart Charging impact my carbon footprint?

On average, charging your vehicle when electricity is cheap, also means you are consuming cleaner electricity. Gridio Smart Charge automatically shifts your vehicle charging to the cheapest hours, which are usually also the time periods with the lowest carbon intensity - thanks to a higher share of wind, solar and sometimes nuclear power providing the electricity.

Our team has done statistical analysis on the relationship between electricity prices and the carbon footprint of electricity which indicates that usually the lower the electricity price, the cleaner the electricity is that is used to charge your vehicle - meaning that you lower the carbon footprint of your driving and also reduce the need for fossil fuel power plant generation by automatically avoiding expensive hours of electricity. 

How does Smart Charging save me money?

Gridio Smart Charge automatically and seamlessly charges your Tesla, Škoda or Volkswagen at the cheapest hours of electricity to give you a full charge by your desired time. By automatically postponing charging if prices are high, and automatically starting charging when prices fall, you can instantly lower your energy bill by charging when it makes most sense.

Does the service drain my battery? Can my car still fall asleep?

We care about the sleep quality of your car! The phenomenon called “vampire drain” is a known issue when using Smart Charging apps. We minimise such drain on your vehicle’s battery by letting the car to go to sleep mode when no immediate smart charge activity is needed. For instance, when the vehicle is not at the designated charging location or you have limtied the time when Gridio is 'active', then we do not interfere with the vehicle in order to let it go to sleep mode.

Can the service damage my car battery?

No. Gridio Smart Charge sets charging schedules in a similar way as the car's own app would, except in real-time and dynamically, and therefore we do not do anything that would damage your vehicle battery. Using Gridio Smart Charge does not impact your vehicle warranty, and such 3rd party services are in compliance with Tesla’s user agreements. 

Where can I get the Gridio app?

The Gridio app can be downloaded from the Apple App Store and Google Play Store.

How much does the service cost?

Gridio is  welcoming users to try out the app free of charge, so that as many users can get access to the service easily as possible. In return, we may bug with occasional requests for feedback to improve the service.

We believe that there will be plenty of opportunities for electric vehicle owners to not just save money on electricity tariffs, but to also to earn money from being flexible with their energy use - either by helping to help balance the grid , or through the use of V2G down the line. We will do our best to keep the app for free until we can prove and bring those sources of value to our users. Nevertheless, we might add premium features, which could come at a cost.

Can I use Gridio Smart Charge with multiple cars?

Gridio Smart Charge currently allows only a single vehicle to be connected per account. We are working on also enabling more than one vehicle to be added.

Can I use Gridio Smart Charge with multiple home locations?

Gridio Smart Charge currently enables only one Smart Charge Location. You can update the location if you go to your summer house or other location where you want Smart Charging to occur by updating the location on your vehicle page in the app. We are working on adding more locations in the future.

How do you ensure my account details are kept safe?
