Estimate how heavily charging ports are used when planning around tire-related EV efficiency changes. Enter port count, operating schedule, session volume, and average charging time to see occupied hours, available hours, utilization, and remaining capacity.
Adjust the inputs to compare your EV charging or energy scenario.
Adjusted session time = base minutes × (1 + tire energy increase). Utilization = occupied port-hours ÷ available port-hours × 100.
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 4 ports, 16 hours/day, 18 daily sessions, 45 minutes/session, 30 days, and a 4% increase, utilization is 21.9%.
| Input | Unit | Example |
|---|---|---|
| Charging ports | ports | 4 |
| Open hours per day | hours | 16 |
| Operating days | days | 30 |
| Charging sessions per day | sessions | 18 |
| Average minutes per session | minutes | 45 |
| Tire-related energy increase | % | 4 |
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.
