Quick Facts
Cold weather reduces Tesla range by 20-40% depending on temperature. At 20°F, expect 30-35% loss. At 0°F or below, losses reach 40-50%. This is normal for all EVs and temporary—range returns when temperatures rise.
Range Loss by Temperature
Here's what to expect at different temperatures. These numbers are based on real-world data from thousands of Tesla owners:
Mild Cold (40-50°F / 4-10°C)
Minimal impact. Battery stays relatively warm. Cabin heating is the main energy drain.
Cold (20-40°F / -7 to 4°C)
Noticeable impact. Battery needs warming. Snowflake icon may appear. Preconditioning helps.
Very Cold (0-20°F / -18 to -7°C)
Significant impact. Battery heating uses substantial energy. Regenerative braking limited.
Extreme Cold (Below 0°F / -18°C)
Severe impact. Battery struggles to maintain temperature. Plan for frequent charging.
Why Cold Weather Reduces Range
Three main factors cause range loss in winter. Understanding these helps you manage expectations:
1. Battery Chemistry Slows Down
Lithium-ion batteries are less efficient in cold. Chemical reactions slow, reducing available power and capacity. This is physics, not a defect.
2. Battery Heating System
Your Tesla actively heats the battery to maintain optimal temperature (50-95°F). This uses significant energy, especially when parked overnight in extreme cold.
3. Cabin Heating
Unlike gas cars that use waste engine heat, EVs must use battery power to heat the cabin. Heat pumps are efficient but still consume 3-6 kW continuously.
Understanding the Snowflake Icon
What It Means
The blue snowflake icon on your touchscreen or app indicates your battery is too cold for optimal performance. This is a protective measure, not a problem.
When Snowflake Appears:
- • Battery temperature below ~40°F (4°C)
- • After sitting overnight in cold weather
- • Before battery has warmed up from driving
What's Limited:
- • Reduced acceleration and top speed
- • Limited or no regenerative braking
- • Slower Supercharging speeds
- • Reduced available range display
How to Remove It:
- • Drive normally for 10-20 minutes
- • Precondition before driving (see related guide)
- • Park in a garage when possible
- • Navigate to a Supercharger to trigger warming
Real-World Winter Examples
Example 1: Model 3 LR in Minnesota Winter
Conditions: 15°F (-9°C), 30-mile highway commute, parked outside overnight
Range Impact:
- • Rated range: 358 miles
- • Actual winter range: 230-250 miles (35% loss)
- • Energy use: 350-380 Wh/mile vs 240 Wh/mile in summer
- • Snowflake icon present for first 15 minutes of driving
Example 2: Model Y in Colorado Mountains
Conditions: 5°F (-15°C), ski trip with elevation gain, heated seats/steering wheel on
Range Impact:
- • Rated range: 330 miles
- • Actual winter range: 195-215 miles (40% loss)
- • Energy use: 400-450 Wh/mile
- • Required charging stop on 200-mile round trip
What's Normal vs Concerning
Normal Winter Behavior
- ✓20-40% range loss in cold weather
- ✓Snowflake icon when cold
- ✓Limited regen braking initially
- ✓Higher energy consumption
- ✓Range returns in warm weather
Concerning Issues
- ✗50%+ range loss in moderate cold
- ✗Snowflake persists after 30+ min driving
- ✗Battery won't warm up at all
- ✗Range doesn't improve in spring
- ✗Error messages about battery heating
