Q. The primary function of a regenerative braking system in electric vehicles is to:

[A] Convert kinetic energy into heat energy

[B] Convert kinetic energy into electrical energy

[C] Increase the speed of the vehicle

[D] Reduce the vehicle weight

Answer: B

Explanation – The primary function of a regenerative braking system in electric vehicles is to convert kinetic energy into electrical energy. It is a brake system designed to convert the kinetic energy of the wheels to a form that can be stored and used for other purposes. Regenerative braking is one type of dynamic braking.
