Logging in with your Tesla Account on app sign up allows you to Smart Charge your Tesla on any brand of home charger. It also means you'll be able to track your charging away from home and better optimize your at home charging. If you own a Rolec HomeSmart EV charge point, you're given the option to login to gain these benefits on sign up - or if you skipped this, you can log in again by navigating to Account > Car Account Settings.


- How does ev.energy use my Tesla login data?


By logging in with your Tesla Account, you allow us to access your Tesla account and read information about your vehicle (such state of charge of your battery and the location) and to control the charging of your vehicle. This means we can Smart Charge your Tesla when we can see your vehicle is at home by starting and stopping charging when energy is at its cheapest and greenest (based on a combination of the cheapest price of energy on your electricity tariff, and the carbon intensity index). 


When you connect your Tesla account, your credentials are passed directly to Tesla.com and we read the access and refresh token provided back, which provides us access to the vehicles on your Tesla account. This process is based on OAuth2, a standard used worldwide to provide secure authentication to services such as Facebook and Google. We only use these tokens to access your vehicles to control your Smart Charging, not for any other purpose. 


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 will refresh automatically every 45 days. 


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

 

You can revoke our access at any time, simply by changing your Tesla account password. We're working on a way of improving this so that in future you can revoke your access straight from the app. 


- I don’t want to hand my Tesla username/password or token details over, but I’m still interested in Smart Charging.


We understand that not everyone is comfortable with handing over these details. You can still Smart Charge without integrating your car by using one of our integrated charge points like the Rolec HomeSmart EV.
