Subtitle: Understanding Range Score and Battery History in Vehicle Insights
Range Score and Battery History both give you information about your EV's battery, but they measure different things. Range Score is about how far your car can go. Battery History is about the physical capacity of the battery pack itself. While the two are related, they can tell different stories.
Range Score
Range Score is a percentage that compares your vehicle's current Expected Range to what was typical for that make, model, and battery configuration when new. A Range Score of 80 means the vehicle is expected to get 80% of its original real-world range.
A few important details about how Range Score is calculated:
- We compare against the vehicle's original real-world range, not its EPA rating. For most non-Tesla EVs, real-world range meets or exceeds the EPA figure — so this is a more meaningful baseline than the EPA sticker.
- Range Score is capped at 100. Some vehicles previously showed scores above 100 when range estimates were based on dashboard figures. Now that Range Score uses real-world observed range as its baseline, scores above 100 are no longer possible.
A note for connected owners: Range Score currently uses fleet-level data for your make, model, year, and battery configuration — not the connected data from your specific vehicle. This means your Range Score reflects how vehicles like yours typically perform, rather than being individualized to your car's unique history. We plan to incorporate connected vehicle data into Range Score in the future.
Battery History
Battery History estimates your battery's current usable capacity compared to its marketed capacity when new — expressed as a percentage of the original pack size. For example, if your vehicle had a 100 kWh battery when new and Battery History shows 92%, Recurrent estimates roughly 92 kWh of that capacity remains usable.
Battery capacity and range are related but not the same thing. A battery that has lost some capacity may still deliver strong range if the vehicle is efficient, and vice versa. Battery History gives you a bigger-picture view of the pack's health independent of day-to-day range estimates.
Battery History is currently available for Tesla vehicles. It is calculated from charging session data.
