Comprehensive HEV Quiz

What is the main purpose of a hybrid electric vehicle (HEV)?

• Improve engine sound

• Increase fuel consumption

• Enhance fuel economy and reduce emissions

• Eliminate the need for brakes

Which hybrid type can operate entirely on electric power for a limited range?

• Mild Hybrid

• Full Hybrid

• Plug-in Hybrid

• Micro Hybrid

In a series hybrid configuration:

• The internal combustion engine (ICE) directly drives the wheels

• The ICE charges the battery or powers the motor-generator

• The motor is only used during deceleration

• There is no energy storage

What is the function of the inverter in an HEV system?

• Convert DC power to AC for the motor

• Charge the battery

• Cool the motor

• Store energy for later use

What component converts DC battery power to AC for the motor?

• Converter

• Alternator

• Inverter

• Resistor

Which of the following is an advantage of a plug-in hybrid (PHEV)?

• It has no internal combustion engine (ICE)

• It can be driven exclusively on electric power for long distances

• It is always in EV mode

• It has a smaller battery compared to other hybrids

Which of the following is a key function of a Battery Management System (BMS)?

• Inflate tires

• Measure engine oil level

• Monitor battery state of charge (SOC) and balance cells

• Drive the vehicle

Which battery type is typically used in most HEVs and EVs for its high energy density?

• NiMH

• Lead-Acid

• Li-ion

• Zinc-air

What does SOC stand for in hybrid systems?

• Standard Operating Condition

• State of Charge

• System On Control

• Standard of Compliance

What is the function of high-voltage (HV) interlocks?

• Enhance acceleration

• Lock vehicle doors

• Detect open connections and disable HV system

• Monitor tire pressure
