1. How does ev.energy use myChevrolet login data? 

By logging in with your myChevrolet account, you allow us access to read information about your vehicle (such as the state of charge of your battery and the location) and to control the charging of your vehicle. This means we can Smart Charge your Chevrolet when we can see your vehicle is at home by starting and stopping charging when energy is at its cheapest and/or greenest.

When you connect your MyChevrolet account, we are encrypting your details and storing them within a secure enclave designed to ensure your security and privacy. For this service, we employ AWS Key Management Service allowing us to ensure that your credentials are only deployed for the purpose of ensuring the connection between our service and your vehicle. For further information, see our privacy policy on how we work to keep you in control of your data.

We take your privacy and security very seriously and we maintain a secure system with regular security tests. This access and refresh token is encrypted, stored securely and your password is not stored on our servers

  1. How do I revoke access / I no longer want to grant ev.energy access

We're working on a way of improving this so that in future you can revoke your access straight from the app but until then, please contact our support team on support@ev.energy - we'll be happy to assist you.

  1. Rate limiting error message: what it means and what to do (turn car off & on again)

Sometimes your Chevrolet vehicle will stop responding to requests. This frequently happens if you don’t drive it for a day or so, or if you check the vehicle status too often (either in the ev.energy app or the myChevrolet app). If this happens, you will see an error message asking you to turn the car on and off again. This wakes the car up again and we can continue to get diagnostics from the vehicle.

  1. ev.energy “ready by time” vs. Chevrolet “departure times”

Your Chevrolet has in-car settings that include a departure-based charging schedule, which ev.energy uses to set the initial value for ready by time in our app. If you have different departure times, we use the most common time in your schedule. If you update your “ready by time” in the ev.energy app, we will update the schedule in your car accordingly, and vice-versa.

  1. Location-based charging session in Chevrolet car

We recommend configuring your Chevrolet vehicle to use Location Based Charging. This will make your car charge immediately when away from home, but use smart charging when at home. It is important that the home location is set correctly, otherwise smart charging won’t work.

In order to Smart charge your vehicle, you will need to update your home location in your Chevrolet. To do so, please follow these instructions:

1. From the infotainment home screen, touch Energy. 

2. Touch Charging. 

3. Touch Charging Options. 

4. Touch Location Based Charging. 

5. Set Home Location. 

6. A pop-up will confirm the setting. In addition, Set Home Location will change to Update Home Location. 

If you already have a home location set in your Chevrolet and need to change it, please follow steps 1-4 above and then follow these instructions:

  1.  Select Update Home Location. 
  2. Select one of the following: 
    • Update : Use when the vehicle is parked in a new location.
    • Cancel : Use to cancel this operation and make no changes.
    • Remove : Use to remove the stored home location from the vehicle. This will turn the feature off because there will be no home location stored.

  1. Why does it take so long to refresh the app?

The General Motors OnStar system can take up to 2 minutes to respond to requests for vehicle information.Unfortunately there’s not much ev.energy can do to speed this up.
