Regenerative Braking and Basic Automotive Concepts Quiz

Study Notes

Inertia is the resistance of an object to change its state of motion.
Electric and hybrid vehicles can reclaim energy through regenerative braking.
Regenerative braking converts kinetic energy into electric energy.
Regenerative braking reduces fuel consumption and extends battery life.
The amount of energy reclaimed depends on vehicle weight, speed, and deceleration rate.
Regenerative braking has limitations, such as only acting on driven wheels and batteries needing to be kept at a maximum of 60%.
Mass is the amount of matter in an object, and weight is the force of gravity on the object.
Regenerative braking may not work if the vehicle is at the top of a hill with a high battery charge level.
Series regenerative braking is proportional to brake pedal position and requires active brake management.
Parallel regenerative braking is less complex and retains front and rear brake balance.

Regenerative brakes use wheel rotation to create electricity.
One-pedal driving allows for acceleration and deceleration with only the accelerator pedal.
Regenerative braking is not 100% efficient and can cause energy loss.
Deceleration rates are measured in feet per second, per second (FPSPS) or meters per sec2 (m/s2).
Most hybrid electric vehicles use unique master cylinders.
Late model GM EVs and PHEVs use an electromechanical brake booster.
The Ford Escape hybrid system has a self-test for the brake system.
To change brake pads, the "Pad Service Mode" must be entered and the self-test disabled.
Disconnecting the wiring harness at the hydraulic control unit is necessary for servicing the braking system.
Smooth driving with no hard acceleration or deceleration is the most efficient driving mode.
