Used electric vehicles experience range degradation based on a number of factors and mileage is not the main source. The calendar age of a battery, charging behavior, and location history are all important factors in degradation, and the complexity of the calculation means that few used EVs have exactly the same battery health.
In order to help you and your customers buy better used EVs, Recurrent produces battery range reports to take the guesswork out of the buying process.
If you want to understand how Recurrent examines thousands of electric cars each day to determine the remaining range that you and your customers can expect from a used EV, read the frequently asked questions below.
If you’d like to add these reports to your dealership VDP, please use the form on this page.
We use a non-invasive, instant test that combines each vehicle’s history and battery data, comparing it to 1000’s of other cars in our database. Our team of battery scientists has developed an algorithm to provide accurate battery health and range predictions across most OEMs and EV models.
We have a number of vehicles running on our advanced analytics program where we install OBD2 devices to confirm and fine tune our predictions based on real world driving. This way, our range degradation modeling continues to get smarter as it sees more and more vehicles, allowing us to be more confident in our range predictions for you.
When Recurrent analyzes an EV for sale or auction, we incorporate that vehicle's odometer, make, model, year, and trim. This informs us on the original battery capacity while providing the information to review against Recurrent’s range prediction model, including thousands of similar EVs that have provided Recurrent with range data every day, sometimes for years.
For an individual vehicle, Recurrent’s range prediction from that model is presented on each vehicle’s full report as a likely minimum and maximum range to be expected. This range prediction is divided by the vehicle’s EPA range. If that ratio is over 90%, it is rated as Excellent.
A Good rating means the range is between 80-90% of its original range. A Fair rating means the vehicle’s max range is less than 80% of original. A future release will see us take more data points from the vehicle during the assessment process in order to provide an enhanced report.
While not a traditionally scientific measure, understanding range is the most practical way for a buyer to understand whether a vehicle meets their needs today, in the future, and in different operating temperatures. That said, the better the max range compared to what it was when it was new, the better the battery.
Yes, Recurrent can add a badge and report to your VDPs to help customers. Please use the form on this page to get started.
Auto manufacturers provide different levels of information about range on their dashboards based on recent driving habits. This is not a good indicator of future range, especially in different climates, which have a measurable impact on range. In a Recurrent report, the vehicle range will reflect the common range at temperatures experienced in your climate and how that could change as the vehicle ages.
Another unique value is that Recurrent’s data spans OEMs to recognize details that a single manufacturer may not see or share. For Recurrent, our only objective is transparency for vehicle buyers and sellers.
Reports include the information that buyers need to feel confident in their purchase. A buyer could be a Used Car Manager at auction or a consumer purchasing an EV.

Here are some examples of critical used EV information found in the Recurrent report:
- Vehicle range at the viewer's local temperatures
- Range relative to original EPA rating
- Expected range 3 years from now
- How this vehicle's range compares to similar vehicles
- Remaining battery warranty information
Recurrent currently supports 70% of all used EVs that transact on the used market in the US. As new models are released, we begin to monitor their battery degradation then release reports when we have a high degree of confidence in our range degradation modeling.
Specific models today include:
- Tesla Model 3
- Tesla Model Y*
- Tesla Model S*
- Tesla Model X
- Chevrolet Volt
- Chevy Bolt EV
- Nissan Leaf
* Tesla Model S 60/60D not scored due to the limited unit production, Tesla Model Y Standard Range not scored due to a limited production - only 2.2% of models.
No. After capturing millions of data points on EV range degradation, we rely on that data to produce a statistically probable range estimate. How that vehicle is ultimately used, where it resides, and how it’s charged may all contribute to ranges that varies from our prediction.
This is the same as how a ‘lead foot’ driver in an combustion engine (ICE) vehicle returns lower MPG or how altitude impacts a naturally aspirated vehicle more than its forced induction counterpart.
