Energy, Heat & MotionElectric Vehicles

Braking Into the Battery

Electric cars recharge a little every time they slow down

Every time a gas car stops at a red light, it throws energy away as heat. Where does an electric car put it?

You'll find out

  • Where a car's motion goes when it stops
  • When the wheels start driving the motor
  • Why some trips win back much more

Why it matters

Every stop and every downhill is energy on the move: catching some of it is why electric cars go farther in town.
