How to use the EV Winter Range Loss Calculator
The Formula
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.
Practical Example
We apply temperature-based loss plus heating load on top of your rated range. Preconditioning while plugged in and seat heaters reduce the hit.

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.
