Monthly Battery Reports

We’ll send you a free battery report specific to your vehicle every month.

Privacy & Security First

Your data is handled securely with end-to-end encryption. You'll review a list of permissions before granting access.

Automated Data Sharing

Once you connect your car once, we pull data automatically. No additional effort, disconnect anytime.

Our Mission

By providing more transparency and confidence in pre-owned electric car transactions, we will accelerate the overall adoption of electric vehicles. This is key to reducing the 20% of U.S. carbon emissions that are currently produced by light-duty combustion engine vehicles.

How can I help?

To get started, you'll securely connect your vehicle with our partner Smartcar to authorize us to access 4 data points from your car daily.

Is my car eligible?

Most major EV models are supported, but there are some year restrictions. You’ll also need an active connected services account. We’ll double check your car’s eligibility as part of the signup process.

How do I benefit?

There’ll be more EV drivers on the road with you in the long-term! Besides that, you’ll receive monthly battery reports for your vehicle for as long as you own it and continue to share data with us.

FAQ

Who is Recurrent?

Recurrent Motors Inc, is a startup funded by investors including Pioneer Square Labs, an incubator in Seattle, Washington. We’re developing a vehicle and battery analysis report for used electric vehicles to provide prospective buyers with the transparency and confidence they need to buy used EVs.

Who is Smartcar?

Smartcar is a third-party data service that enables Recurrent to connect to your car. They use industry-standard end-to-end 256-bit encryption to ensure that your vehicle data and credentials are transmitted securely. Smartcar securely handles and encrypts your login credentials and does not share them with Recurrent. Recurrent is only granted the ability to access the data listed on the permissions page during the connection process.

What data are you collecting?

Once you authenticate your vehicle, Recurrent will be able to connect directly to your vehicle to request specific data: VIN, current odometer, current state of charge, current charging status and current range estimate. Recurrent will typically make these data requests 1-3 times per day to build up a historical profile.

What is the process of connecting my car?

This process uses the credentials you provide to your car’s connected services account (such as Nissan Connect EV, BMW ConnectedDrive, or Tesla’s API). Once you authenticate your car, you will be presented with a list of data that Recurrent will be allowed to access. After accepting the permissions page, you’re finished and will receive a confirmation email from Recurrent.

Why do you need this data?

EV batteries last for a long time, but like your iphone, their capacity fades over time. Complex factors like temperature, age, cycle count, charging type, driving style, battery chemistry and layout, influence how that occurs. It’s not just the odometer, like it is with combustion engine vehicles. We’re trying to help prospective used EV buyers get comfortable with the idea of purchasing a battery that has been used by giving them transparency. To do that, we need your help. We’ll be aggregating all this data from a large training data fleet of vehicles across all manufacturers to create predictive algorithms for any car’s future battery life.

Is my car eligible to participate?

Most major EV models are supported, but there are some year restrictions. You’ll also need an active connected services account. We’ll double check your car’s eligibility as part of the signup process. Currently supported (as of July 2020): Tesla Model 3, S, X; Nissan Leaf 2016 and later; BMW i3 2017 and later, X5, i8, 5-series plug-in, 3-series plug-in; Ford Fusion Energi 2019 and later; Chevy Volt, Bolt, Spark; VW e-Golf; Jaguar I-Pace; Chrysler Pacifica Plug-in; Audi e-tron, Audi A3 Plug In.

Check eligibility

Do you support multi-factor authentication for Tesla vehicles?

Yes. If you have enabled multi-factor authentication on your Tesla account, you'll be prompted to authenticate during the connection process.

What is the process of connecting my car?

This process uses the credentials you provide to your car’s connected services account (such as Nissan Connect EV, BMW ConnectedDrive, Tesla’s API, etc). Once you authenticate your car, you will be presented with the limited list of data that Recurrent will be allowed to access. This is a similar connection and granular permissions approach used by other popular third party apps (e.g. Remote for Tesla and TeslaStats). After accepting the permissions page, you’re finished and will receive a confirmation email from Recurrent. You don’t need to do anything else to continue data sharing on an ongoing basis.

If I change my mind later about being in the research panel, how can I revoke permission?

You can disconnect and revoke your authorization at any time by visiting our Disconnect page. We won’t be able to send you monthly battery comparison reports if we can’t continue to observe your battery.

Is this safe? What happens with my vehicle login credentials after I enter them?

Your credentials are not stored by Recurrent or Smartcar. They are used only once to generate a unique authorization token via an industry-standard protocol known as OAuth 2.0. This token is then used by Recurrent for all future data requests. Your credentials and authorization token are always transmitted using end-to-end 256-bit encryption.

What about my privacy?

The data collected for this research panel is about your vehicle, not about you. As part of the signup process, we ask for your home zip code to determine the temperatures your vehicle is exposed to — that’s important information for battery health analysis. But we do not track where you’re driving, just the battery’s state and your overall mileage.As a part of this research study, your vehicle’s data will only be used in aggregate to train a machine learning model used to score EVs that are listed for sale. Your vehicle’s data will never be used or disseminated individually.
