Question 1: How do you ensure proper thermal management in high-power electrical systems within an automotive vehicle?

Which action should you take?

Choose only one option

By reducing the power requirements of the systems

By designing for adequate ventilation, heat dissipation materials, and thermal shielding

By using only passive cooling techniques

By ignoring temperature variations and focusing on voltage stability

Question 2: What steps do you take when diagnosing a problem with a vehicle's alternator not charging the battery properly?

Which action should you take?

Choose only one option

Check only the alternator's appearance without testing its output

Measure the voltage at the battery, check the alternator belt, and test the voltage regulator

Test the battery voltage without checking the alternator's performance

Simply replace the alternator

Question 3: In automotive electrical design, what does the term "can bus" refer to?

Which action should you take?

Choose only one option

A type of battery storage system for electric vehicles

A safety system designed to protect the electrical circuits

A voltage regulation system for the alternator

A communication system for exchanging data between vehicle control units

Which action should you take?

Choose only one option

Switching Regulators

Analog Front-End (AFE) Circuits

Optocouplers

Power MOSFETs

Question 5: In control systems for electric vehicles, what is the role of the powertrain control module (PCM)?

Which action should you take?

Choose only one option

To provide a communication link between the ECU and battery pack

To manage the interaction between the battery, motor, and inverter for optimal performance

To control the vehicle's steering system during turns

To monitor tire pressure and adjust vehicle speed

Question 6: In Vehicle-to-Everything (V2X) communication systems, how do control systems enhance vehicle safety and performance?

Which action should you take?

Choose only one option
