Estimate added battery wear associated with increased energy use from tire pressure, rolling resistance, or tire choice. The calculator separates calendar degradation from cycle-related degradation and shows the incremental effect attributed to tires.
Adjust the inputs to compare your EV charging or energy scenario.
Equivalent cycles = annual battery energy ÷ usable capacity. Estimated degradation = calendar loss + equivalent cycles × loss per cycle.
This is a planning model; actual EV and charger performance can vary with temperature, equipment, and operating conditions.
The main result summarizes the modeled outcome from your inputs. Secondary results expose the energy, time, capacity, or cost components so you can identify which assumption drives the estimate.
At 12,000 miles, 0.30 kWh/mile, 5% extra energy, 70 kWh capacity, 0.025% per cycle, and 1.5% calendar loss, estimated annual degradation is 2.85%.
| Input | Unit | Example |
|---|---|---|
| Distance driven per year | miles | 12000 |
| Baseline energy use | kWh/mile | 0.30 |
| Tire-related energy increase | % | 5 |
| Usable battery capacity | kWh | 70 |
| Capacity loss per equivalent cycle | % | 0.025 |
| Annual calendar degradation | % | 1.5 |
The energy, power, time, or utilization inputs that appear directly in the formula have the greatest effect. Change one input at a time to compare scenarios.
No. It is a planning estimate based only on the values you enter and does not connect to a vehicle, battery-management system, charger, or utility account.
Enter percentages as displayed numbers, such as 90 for 90%. The calculator converts them to decimal form internally.
Temperature, battery conditioning, charging curves, vehicle limits, tire condition, station sharing, fees, and driving conditions can change real-world results.
Yes. Calculate the first scenario, note the results, then change one or more inputs. The reset button restores the example defaults.
