Estimate charging-port utilization when EV heat-pump loads lengthen sessions. Compare scheduled capacity with adjusted occupied time and see how many sessions the site can accommodate under the entered conditions.
Adjust the inputs to compare your EV charging or energy scenario.
Adjusted session time = base time × charger output ÷ (charger output − heat-pump draw). Utilization = adjusted occupied hours ÷ available port-hours.
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.
Six ports open 18 hours with 30 daily 50-minute sessions, 11 kW chargers, and a 1.2 kW heat-pump draw produce about 26.0% utilization.
| Input | Unit | Example |
|---|---|---|
| Charging ports | ports | 6 |
| Available hours per day | hours | 18 |
| Sessions per day | sessions | 30 |
| Base session time | minutes | 50 |
| Charger output | kW | 11 |
| Average heat-pump draw | kW | 1.2 |
| Days in period | days | 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.
