Why winter reduces EV range
Cold batteries have higher internal resistance, and cabin heat draws significant energy. Combined losses of 20–35% are common in freezing conditions with full heat.
How this estimate works
We apply temperature-based loss plus heating load on top of your rated range. Preconditioning while plugged in and seat heaters reduce the hit.
Frequently asked questions
Q: Should I use EPA range? A: Yes, as a baseline—your trip computer may already adjust. Q: What about highway speed? A: This tool isolates temperature/heat; high speed adds further loss.
