The electric drive system in a hybrid vehicle is being discussed. Technician A says the electric drive system increases the speed of the internal combustion system increases the speed of the internal combustion up to 2,500 rpm whenever the vehicle is stopped and idling. Technician B says the regenerative braking system adds mechanical stress and intensifies part wear of the conventional friction brake pads and brake rotors. Who is right?

Answers

Answer 1

The statement made by Technician A is inaccurate. The hybrid car's electric propulsion system does not boost the idle speed of the internal combustion engine.

Why is Technician A incorrect?

Rather than idling the engine, the electric motor is usually able to supply power when the vehicle is at a standstill or moving at a slow pace, thus resulting in reduced or eliminated engine idle needs.

The accuracy of Technician B's statement is somewhat accurate. Hybrid cars' regenerative braking systems efficiently accumulate the energy released during deceleration, converting it into electrical energy and storing it in the battery.

The system's responsibility of reducing the vehicle's speed can actually diminish the wear on usual brake components, rather than intensifying it. The reason for this is that the vehicle requires lower levels of friction when the regenerative braking is actively assisting in decelerating.

Both Technician A and Technician B are partly erroneous in their assertions.
