Winter EV Range Calculator
See how cold weather affects your EV's range. Select your vehicle and city to get real winter estimates — heat pump advantage included.
| Temperature | With Heat Pump | Without Heat Pump | No Heat (max range) |
|---|---|---|---|
Avg coldest month (11°F) | 206 mi(58%) | 186 mi(52%) | 224 mi |
20°F cold day | 244 mi(68%) | 220 mi(61%) | 265 mi |
0°F extreme cold | 165 mi(46%) | 149 mi(42%) | 179 mi |
Record low (-41°F) | 3 mi(1%) | 2 mi(1%) | 3 mi |
The Tesla heat pump moves heat rather than generating it, using 50-70% less energy than a resistive heater. This is the single biggest factor in winter range retention.
How Winter Range Is Calculated
Range calculations use a physics-based temperature coefficient model. Cold temperatures affect range in two ways: (1) the battery itself has higher internal resistance, reducing capacity — this effect steepens below 32°F and becomes severe below 20°F; (2) cabin heating draws power directly from the traction battery. A heat pump reduces (2) by 50-70% vs resistive heat by moving heat from outside rather than generating it. The model is calibrated against Recurrent Auto and Geotab real-world EV fleet data.
