Climate Case Battery Runtime Transport Calculator
Budget climate-case runtime under measured energy, explicit mode duty/conversion loss/reserve; no fixed battery capacity, temperature derating or guaranteed climate control.
Description
Battery runtime depends on mode duty and conversion losses as well as usable energy.
Battery runtime depends on mode duty and conversion losses as well as usable energy. A reserve reduces the usable portion.
Budget climate-case runtime under measured energy, explicit mode duty/conversion loss/reserve; no fixed battery capacity, temperature derating or guaranteed climate control.
When to use Climate Case Battery Runtime Transport Calculator
Use this tool to budget climate-case runtime under measured energy, explicit mode duty/conversion loss/reserve; no fixed battery capacity, temperature derating or guaranteed climate control.
Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
How to use Climate Case Battery Runtime Transport Calculator and understand its results
- Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
- Enter measuredBatteryEnergyWh, callerReservedEnergyWh, powerWattsByOperatingMode, modeDutyFractions, powerConversionEfficiency using the field table and calculation rules, then run the tool.
- Read averageBatteryDemandWatts, modeledUsableRuntimeHours. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| measuredBatteryEnergyWh | Measured battery energy wh | number | Required |
| callerReservedEnergyWh | Caller reserved energy wh | number | Required |
| powerWattsByOperatingMode | Power watts by operating mode | list of number | Required |
| modeDutyFractions | Mode duty fractions | list of number | Required |
| powerConversionEfficiency | Power conversion efficiency | number | Required |
Align nonnegative watts with fractions in [0,1] summing to one within 1e−12. Use efficiency in (0,1], reserve no greater than nonnegative measured Wh and require positive average demand.1
Paired lists must be nonempty and have equal lengths.
battery demand = Σ mode watts × duty/efficiency; hours = (energy − reserve)/demand Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| averageBatteryDemandWatts | Average battery demand watts | number |
| modeledUsableRuntimeHours | Modeled usable runtime hours | number |

}Limitations and assumptions
No fixed battery capacity, temperature derating or climate-control guarantee.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
