Slide the temperature. Estimates use your car's real EPA range plus published fleet-study data — not guesses.

Anchor points come from published studies: AAA measured ~17% range loss at 95°F with A/C and ~41% at 20°F with heat on (2019, 5 EVs); Recurrent's fleet data shows ~25–30% loss at freezing. We interpolate linearly between 95°F (×0.88), 70°F (×1.00), 32°F (×0.78), 20°F (×0.70) and 0°F (×0.60); resistive-heater cars lose an extra ~8 points below freezing. Below 0°F is extrapolated. This is an estimate, not a measurement — wind, speed, snow tires, and battery preconditioning all move the real number. See real-world range tests for measured data.
Typically 20–35% at freezing (32°F) versus mild weather, depending on the car and whether it has a heat pump. At 20°F, losses can reach 35–40% with the cabin heat on.
Yes. Heat pumps move heat instead of generating it, using far less battery than resistive heaters. Most 2024 and newer EVs include one.
No. Cold temporarily reduces available range and slows fast charging; range returns as the battery warms.
