Exam 36: Electric Vehicles

Which of the statements about hydrogen is NOT true?

The Nissan Leaf is a true ZEV with zero tailpipe emissions.

A fuel cell converts fuel into electricity.

There are two basic ways a BEV is connected to an external source of electricity for charging: conductive and inductive. What is the difference between the two?

Which of the following CANNOT be used as a source for the production of hydrogen?

While discussing diagnosis of the control system of a BEV: Technician A begins by checking the voltage of the auxiliary battery. Technician B inspects all fuses, fusible links, wiring harness, connectors, and ground in the low-voltage circuit. Who is correct?

Technician A says with Conductive charging there is no metal-to-metal contact between the charge paddle and the charge port of the vehicle. Technician B says Inductive charging takes place by making a connection between the charging connector and the charge port. Who is correct?

The Tesla Roadster uses Nickel-metal hydride batteries.

Technician A says that gasoline can be used as a source of hydrogen for a fuel cell. Technician B says that carbon dioxide can be used as a source of hydrogen for a fuel cell. Who is correct?

Most production BEVs use _______________type motors.

Explain what the ratings of kilowatts and kilowatt hours mean.

A PEM fuel cell needs to operate at very high temperatures.

A fuel cell produces electricity through electrolysis.

While discussing inductive charging: Technician A says most current BEVs use this system because it is safe. Technician B says this method requires that a weatherproof paddle be inserted into the vehicle's charge port. Who is correct?

Technician A says a motor converts electrical energy into mechanical energy. Technician B says an engine converts chemical energy into mechanical energy. Who is correct?

Most EVs the motor increases torque so there in no need for a _____________.

While discussing charger connections: Technician A says nearly all BEVs currently sold in North America have an AVCON connector. Technician B says the connector currently used for DC fast charging on the Nissan Leaf and Mitsubishi i vehicles is based on the CHAdeMO standard. Who is correct?

Why are carbon dioxide emissions a concern?

While discussing hydrogen: Technician A says that a hydrogen atom has one proton and two electrons. Technician B says that hydrogen is produced in a fuel cell when water is broken down into its basic elements. Who is correct?

Fuel cell electric vehicles are also electrically powered low-emission vehicles.
