Estimate usable driving range consumed by reaching and waiting at a charging station. Combine detour distance with idle climate energy to see total range impact, arrival energy use, and the percentage of starting range spent on access.
Adjust the inputs to compare your EV charging or energy scenario.
Idle-equivalent miles = climate power × wait hours ÷ driving energy per mile. Total range used = detour miles + idle-equivalent miles.
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.
With 240 miles of starting range, an 8-mile detour, 25 minutes at 1.5 kW, and 0.30 kWh/mile, station access uses about 10.1 miles.
| Input | Unit | Example |
|---|---|---|
| Starting estimated range | miles | 240 |
| Round-trip station detour | miles | 8 |
| Queue and idle time | minutes | 25 |
| Idle climate draw | kW | 1.5 |
| Driving energy use | kWh/mile | 0.30 |
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.
