How Temperature Affects Your EV's Range

Why winter range drops, why it isn't a fault, and what you can do to minimise the hit.

Why cold weather reduces range

  • Battery chemistry slows down in the cold
  • Cabin heating draws power directly from the traction battery
  • Battery preconditioning before a rapid charge uses energy too

It isn't a fault

It's common to see a noticeable range reduction in cold winter conditions compared with a mild spring day. The exact percentage varies by car, but it's a real and expected effect — not a fault.

Hot weather has an impact too

  • Air conditioning draws power, similar to heating
  • Very high temperatures affect battery efficiency and long-term health
  • Most EVs have thermal management systems that protect against this

How to minimise the effect in winter

  • Precondition while plugged in — use grid electricity, not battery
  • Prefer seat and steering heaters over cabin air heating
  • Keep your battery in a reasonable charge range
  • Keep tyres properly inflated
  • Reduce speed slightly on longer winter trips

Planning around the season

Build in a bigger buffer than you would in summer, and don't assume your usual range holds through winter. Route planners like ABRP can adjust for temperature — worth using for any unfamiliar winter trip.

The reassuring part

Range recovers as temperatures rise — it isn't a permanent loss of battery capacity, simply a temporary efficiency change. Long-term degradation is a separate topic entirely.
