1. How does lidar commonly help an automated vehicle perceive its surroundings?
By reading magnetic strips embedded in every road
By detecting only sounds reflected from nearby objects
By using emitted light pulses and their reflections to estimate distance
By measuring tire pressure changes caused by obstacles
2. A battery pack contains cells that have developed slightly different charge levels. Which system is designed to monitor and help manage this imbalance?
The satellite navigation system
The battery management system
The anti-lock braking controller
The exhaust after-treatment system
3. When an electric car is connected to a standard AC charging point, which component normally converts AC electricity into DC for the battery?
The traction inverter alone
The regenerative braking controller
The vehicle’s onboard charger
The cabin climate compressor
4. A car charges while parked over a compatible pad without a cable connection. Which physical principle is normally used to transfer the energy?
Electromagnetic induction between aligned coils
Solar concentration through the windshield
Regenerative braking while stationary
Combustion inside the charging pad
5. An EV consumes noticeably more energy per mile after its driver greatly increases motorway speed. What is the strongest explanation?
The electric motor stops producing torque at cruising speed
Regenerative braking becomes the car’s main power source
The battery changes from DC storage to AC storage
Aerodynamic drag rises substantially as speed increases
6. A manufacturer fixes an infotainment bug without requiring owners to visit a service center. Which connected-car feature made this possible?
Regenerative braking
Vehicle-to-grid charging
Mechanical energy recovery
An over-the-air software update
7. Two cars have similar energy use on the road, but their production processes and energy sources differ. Which method gives the fairest environmental comparison?
Comparing only their tailpipe emissions
Assessing impacts across production, use, energy supply, and end of life
Comparing only the materials used in their batteries
Assessing whichever car has the longer driving range
8. On a cold day, an EV driver plans to use a rapid charger. Which action can help the battery accept power more effectively?
Discharge the battery completely before plugging in
Turn off regenerative braking for the entire journey
Precondition the battery before reaching the charger
Inflate the tires beyond the vehicle maker’s specified pressure
9. An automated-driving system compares camera images, radar measurements, and lidar data before identifying an obstacle. What is this approach called?
Sensor fusion
Geofenced charging
Battery cell balancing
Mechanical redundancy
10. What principally distinguishes a solid-state battery from a conventional lithium-ion battery with a liquid electrolyte?
It stores energy mechanically in rotating components
It uses a solid material to conduct ions between its electrodes
It generates electricity by combining hydrogen and oxygen
It can operate without positive and negative electrodes
11. Why can a heat pump help an electric car preserve more driving range in cold weather than conventional resistive cabin heating?
It creates heat without using any electrical energy
It moves heat efficiently instead of producing all heat through electrical resistance
It converts the battery from lithium-based storage to thermal storage
It heats only the tires and relies on them to warm the cabin
12. What is the main purpose of regenerative braking in an electric or hybrid car?
To apply only the mechanical brakes at lower speeds
To cool the battery by increasing airflow beneath the car
To disconnect the motor so the car can coast indefinitely
To recover some of the car’s kinetic energy as electrical energy
13. A shared residential garage wants to charge several EVs without exceeding the building’s electrical capacity. Which solution best addresses this problem?
Dynamic load management that distributes available power among chargers
A separate traction motor installed beside every charger
Disabling each vehicle’s battery management system
Running all chargers at maximum power at exactly the same time
14. A car uses adaptive cruise control and lane centering classified as SAE Level 2 automation. What must the driver do?
Monitor only when the road lacks lane markings
Move to a passenger seat once both features are active
Stop paying attention unless the car issues an emergency alert
Continuously supervise the system and remain responsible for driving
15. What does vehicle-to-grid, or V2G, technology allow a compatible electric vehicle to do?
