Estimate how heat-pump energy throughput may contribute to annual equivalent battery cycles and modeled capacity loss. The estimate combines driving energy, climate energy, calendar loss, and a user-entered degradation rate per cycle.
Adjust the inputs to compare your EV charging or energy scenario.
Annual throughput = driving energy + heat-pump power × operating hours. Equivalent cycles = throughput ÷ usable capacity. Modeled loss = calendar loss + 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, 0.29 kWh/mile, 1.3 kW for 300 hours, 72 kWh capacity, 0.025% per cycle, and 1.5% calendar loss, modeled annual degradation is 2.84%.
| Input | Unit | Example |
|---|---|---|
| Annual distance | miles | 12000 |
| Driving energy use | kWh/mile | 0.29 |
| Heat pump draw | kW | 1.3 |
| Annual heat-pump hours | hours | 300 |
| Usable battery capacity | kWh | 72 |
| Capacity loss per equivalent cycle | % | 0.025 |
| Annual calendar loss | % | 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.
