BEV
Which of the following best describes the traction motor used in most current EVs?
Series wound dc
Brushless dc
AC motor-generator
Asynchronous dc
Technician A says that EVs use PMEs to rectify ac to dc electrical current. Technician B says that EVs use PMEs to invert dc to ac electrical current. Who is correct?
Technician A only
Technician B only
Both A and B
Neither A nor B
What is the blended torque device used in a standard Toyota HEV drive train?
PSD
BTD
Traction motor
PME module
Technician A says a typical BEV uses a series-parallel drive train. Technician B says that the typical HEV uses a series drive train. Who is correct?
Technician A only
Technician B only
Both A and B
Neither A nor B
In a typical EV, from which electrical device does the traction motor receive ac electrical energy sufficient to power the vehicle?
BCM
PCM
PME module
EESS module(s)
In an HEV drive train using a blended torque transmission (BTT), what BTT component produces the electrical energy that is stored in the EESS?
Clutch
Transmission gearing
Reduction gearing
Motor-generator
In a typical EV drive train that locates a pair of traction motors at either wheel-end of a drive axle, which of the following is usually located between the motor and the drive wheel?
Nothing, direct drive is common
Reduction gearing
Overdrive gearing
Overrunning clutch
Which of the following best describes the role of the fuel cell in an FCEV drive train?
Produces electrical energy
Functions as the EV battery
ICE fuel by hydrogen (H2)
Outputs traction torque using a thermochemical reaction
In a typical EV, which of the following components are managed by PCM/BMS/PME electronics?
EESS
Traction motor(s)
Current rectification and inversion cycles
All of the above
If there was no choice but to purchase an automobile with an electric drive train, the best option to select would be:
Battery Electric Vehicle (BEV) because it has zero emissions, lower maintenance, and is more environmentally friendly.
Hybrid Electric Vehicle (HEV) because it combines a gasoline engine with electric power for longer range.
Plug-in Hybrid Electric Vehicle (PHEV) because it can run on both electricity and gasoline for flexibility.
Fuel Cell Electric Vehicle (FCEV) because it uses hydrogen and emits only water vapor.
A total ban on ICE-fueled vehicles in some cities could lead to which of the following effects?
Reduced air pollution and noise
Increased use of gasoline
Lower costs for new vehicles
More reliance on ICE vehicles
