    What defines a Hybrid Electric Vehicle (HEV)?

    Combines mechanical and electrical propulsion for improved efficiency.

    How does an HEV differ from a pure electric vehicle?

    Uses both an internal combustion engine and electric motor.

    What is the role of the internal combustion engine in an HEV?

    Converts chemical energy from fuel into mechanical energy.

    What energy sources can be used in an HEV?

    Includes ICE, battery, fuel cell, capacitor, and flywheel.

    Why do HEVs have better fuel economy than conventional vehicles?

    Utilize multiple energy sources for higher overall efficiency.

    What is a key feature of the electric motor in an HEV?

    Delivers traction power and works with the combustion engine.

    How does an HEV manage energy sources?

    Coordinated by an intelligent control system for optimal performance.

    What advantage do HEVs have over pure electric vehicles?

    Avoid range limitations by using multiple energy sources.

    What is the function of a battery in an HEV?

    Stores electrical energy for propulsion and auxiliary loads.

    What distinguishes an HEV from a conventional ICE vehicle?

    Incorporates electric components to assist in propulsion.

    What is the most common HEV configuration?

    Petrol ICE combined with a battery.

    How does the electric motor function in a petrol HEV?

    It assists during starting and acceleration.

    What is a key benefit of petrol HEVs?

    They offer smooth operation and low emissions.

    What distinguishes diesel HEVs from petrol HEVs?

    Diesel engines provide high torque and better efficiency at high loads.

    What is a primary advantage of diesel HEVs?

    Better efficiency for long-distance and heavy-load operation.

    What role does the fuel cell play in an ICE + Battery + Fuel Cell configuration?

    It generates electrical energy continuously and acts as a range extender.

    What is the function of a supercapacitor in an ICE + Battery + Capacitor system?

    It absorbs energy quickly and supplies short bursts of power.

    How does the use of a flywheel benefit an HEV?

    It stores energy in rotational form and responds quickly to braking.

    What is the purpose of using multiple battery systems in an HEV?

    To optimize for both high energy density and high power output.

    What does intelligent energy management do in a multi-battery HEV?

    Decides which battery to use for improved reliability and lifespan.
