About the EV Range Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
_bkwh = parseFloat(battery_kwh)
_eff = parseFloat(efficiency_mi_kwh)
_up = parseFloat(usable_pct) || 90
_tf = parseFloat(temp_factor) || 1.0
usable_kwh = _bkwh * (_up / 100)
range_miles = Math.round(usable_kwh * _eff * _tf)
range_km = Math.round(range_miles * 1.60934)
kwh_per_100miles = 100 / _eff
charges_for_500mi = Math.ceil(500 / range_miles)
range_category = range_miles >= 300 ? 'Long Range (300+ mi): Road trip capable': range_miles >= 200 ? 'Mid Range (200-299 mi): Good for most needs': range_miles >= 100 ? 'Short Range (100-199 mi): City and local commuting': 'Limited Range (<100 mi): Urban use only'
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: _bkwh = parseFloat(battery_kwh) _eff = parseFloat(efficiency_mi_kwh) _up = parseFloat(usable_pct) || 90 _tf = parseFloat(temp_factor) || 1.0 usable_kwh = _bkwh * (_up / 100) range_miles = Math.round(usable_kwh * _eff * _tf) range_km = Math.round(range_miles * 1.60934) kwh_per_100miles = 100 / _eff charges_for_500mi = Math.ceil(500 / range_miles) range_category = range_miles >= 300 ? 'Long Range (300+ mi): Road trip capable': range_miles >= 200 ? 'Mid Range (200-299 mi): Good for most needs': range_miles >= 100 ? 'Short Range (100-199 mi): City and local commuting': 'Limited Range (<100 mi): Urban use only' Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Tesla Model 3 Long Range: 82 kWh, 4.1 mi/kWh, ideal conditions
Inputs
With Battery Capacity = 82, Efficiency = 4.1, Usable Battery% = 92 and Temperature Adjustment = 1 as the stated inputs, the result is Usable Battery = 75.4 kWh, Estimated Range = 309 mi and Estimated Range = 497 km. Each value corresponds to the declared output fields.
Example 2: Chevy Bolt EV: 65 kWh, 3.5 mi/kWh, cold winter day (Chicago)
Inputs
With Battery Capacity = 65, Efficiency = 3.5, Usable Battery% = 90 and Temperature Adjustment = 0.78 as the stated inputs, the result is Usable Battery = 58.5 kWh, Estimated Range = 160 mi and Estimated Range = 257 km. Each value corresponds to the declared output fields.
Example 3: Rivian R1T truck: 135 kWh, 2.4 mi/kWh, highway towing
Inputs
With Battery Capacity = 135, Efficiency = 2.4, Usable Battery% = 88 and Temperature Adjustment = 0.92 as the stated inputs, the result is Usable Battery = 118.8 kWh, Estimated Range = 262 mi and Estimated Range = 422 km. Each value corresponds to the declared output fields.
Example 4: Nissan Leaf Plus (10 yr old battery): 62 kWh degraded to 85%
Inputs
With Battery Capacity = 62, Efficiency = 3.3, Usable Battery% = 85 and Temperature Adjustment = 0.95 as the stated inputs, the result is Usable Battery = 52.7 kWh, Estimated Range = 165 mi and Estimated Range = 266 km. Each value corresponds to the declared output fields.
