Exam 80: Hybrid Electric Vehicle Fundamentals

Which of the following  is LEAST-Likely to be a type of supercapacitor?

In a conventional DC motor, electrical arcing not only causes wear but results in electrical interference in computer circuits. A(n) ____________________  has no commutator or brushes, so arcing cannot occur.

What is the memory effect that occurs in some rechargeable batteries?

The ____ determines when to turn the engine on and off.

Most hybrid automobiles are powered with an ICE or a battery-powered electric motor/generator (MG), but not both at the same time.

Which of the following statements about supercapacitors is LEAST-Likely to be true?

Conventional 12-volt lead-acid batteries are  used in all electric motor-powered vehicles.

What are the advantages of hybrids?

The ____ is the interconnected network that moves electricity from generating stations to customers throughout the world.

Pulse and glide driving when accelerating and decelerating is best for ____________________.

The batteries in parallel and series/parallel hybrids are charged either by the engine or by  ____________________.

A micro hybrid or stop-start hybrid has a more robust generator that also acts as a starter. It is known as a(n) ____________________ and is powered by a belt drive attached to the crankshaft.

Technician A says that automotive parallel and series/parallel hybrids have their batteries charged by the engine. Technician B says that they are powered by regenerative braking. Who is correct?

While having a discussion, Technician A says to be careful when working or inspecting under the hood. If the READY light is on, the engine can start at any time. Technician B says that only pushing the START button will start the engine. Who is correct?

All of the following are hybrid classifications EXCEPT:

The larger Toyota and Lexus hybrids use an additional third electric motor on the ____________________ to provide extra acceleration, all-wheel drive, and traction control.

Some hybrid vehicles have used CVT or conventional automatic transmissions, but many other hybrids use a unique transmission known as an ECVT or electronically controlled continuously variable transmission. What is the difference?

Briefly describe the difference between a motor and an engine.

In the Toyota hybrid system (THS), hybrid motor/generators operate as motors when they power a vehicle. They can also generate electricity to recharge the battery pack.  Describe the functions of Motor/Generator 1 and Motor/Generator 2.

All of the following statements are true EXCEPT:
