What is a primary benefit of regenerative braking?

• A. Recovering kinetic energy as electrical energy for reuse.
• B. Increasing wear on friction brakes.
• C. Reducing energy efficiency.
• D. Requires no electrical energy.

Answer: (A)

Regenerative braking captures the vehicle’s kinetic energy and converts it into electrical energy for storage and later reuse. When braking, the traction motor runs as a generator, sending electricity back into the battery or energy storage system. This recovery of energy directly boosts overall efficiency by keeping energy that would otherwise be lost as heat in the brakes. It can also reduce wear on friction brakes because a portion of braking is handled electronically, not purely by the brake pads. The other options don’t fit: increasing friction-brake wear isn’t correct, reducing energy efficiency isn’t correct, and requiring no electrical energy is incorrect because it relies on generating and storing electrical energy.
