Exam 36: Electric Vehicles

While discussing diagnosis of an illuminated Malfunction Indicator Light (MIL) on the instrument panel of a BEV: Technician A says diagnosis of BEV concerns are much more difficult than diagnosing concerns on a conventional vehicle because there are more components.. Technician B says faults held in the computer's memory can be retrieved as DTCs.Who is correct?

Technician A says power is the ability to do work. Technician B says energy is the rate at which work is done. Who is correct?

Electrolysis is the process in which hydrogen and oxygen are combined to form water.

A gasoline engine provides more torque at lower speeds than an electric motor.

Why is water purity so important to the effectiveness of a PEM fuel cell?

A ______ _____ produces electricity through an electrochemical reaction that combines hydrogen and oxygen to form water.

Which of the following statements about fuel cells is NOT true?

All fuel cell vehicles have regenerative braking and 12-volt auxiliary systems.

What basic factors affect the required time to recharge the battery pack in a BEV?

In a PEM, the electrolyte is a polymer membrane, called the proton exchange membrane.

Technician A says that all FCEVs have regenerative braking. Technician B says that all FCEVs have an auxiliary 12-volt battery. Who is correct?

Compressed hydrogen used in FCEVs [fuel cell electric vehicle] is stored at approximately ______ psi.

Technician A says that a fuel cell produces electricity through an electrochemical reaction that combines hydrogen and oxygen to form water. Technician B says that in a fuel cell, catalysts are used to ignite the hydrogen, causing a release of electrons or electrical energy. Who is correct?

Hydrogen-fueled vehicles are being discussed. Technician A says hydrogen [H₂] can be made from natural gas. Technician B says hydrogen can be made from water. Who is correct?

Technician A says some BEVs use liquid to heat the passenger compartment. Technician B says some BEVs use an electric resistance heater with a fan to heat the passenger compartment. Who is correct?

What is the basic fuel for a fuel cell?

Which of the following statements about hydrogen is NOT true?

Why won't fuel cell vehicles be available for sale in the next few years?

List the precautions during recharging to be observed on a BEV.

Conductive charging is normally accomplished with a fuel nozzle looking connector called the ODU.
