Traffic jams and your battery

Checked 2 October 2026.

An electric car in a traffic jam uses very little energy. There's no engine idling: the car only uses power for the screen, lights and, mainly, heating or air conditioning.

How long can you sit with the heating on?

Heating or cooling a cabin usually takes a few kilowatts at first, then less once the cabin is at temperature. With a reasonable amount of charge, a Tesla can keep you warm for many hours in a stationary queue. That's often longer than a petrol car on a low tank.

In a long closure

  1. Turn on Camp Mode if you'll be stopped for a long time. It keeps the climate and screen running steadily. See Camp Mode.
  2. Use seat heaters and a lower cabin temperature to save energy.
  3. Keep an eye on the battery and the distance to the next charger.
  4. Follow police and National Highways instructions.

Crawling traffic

Stop-start traffic is efficient in an electric car because regenerative braking recovers energy. You may find range goes further in slow traffic than at 70 mph.
