Series–parallel hybrid and range-extender layouts.

Hydrogen fuel-cell and plug-in hybrid layouts.

How do electric vehicles contribute to reducing greenhouse gas emissions?

They produce zero tailpipe emissions and can use cleaner energy sources, reducing overall greenhouse gas emissions.

They produce more carbon dioxide than diesel vehicles.

They burn diesel more efficiently than petrol cars.

They use leaded petrol which lowers emissions.

What is the function of the Battery Management System (BMS) in an EV?

It monitors battery temperature, voltage, and current, ensuring safe charging, discharging, and overall battery protection.

It inflates the tires automatically.

It controls the windshield wipers.

It tunes the infotainment system.

What are the advantages of using solar panels for EV charging?

Solar charging is renewable, eco-friendly, reduces dependence on the electricity grid, and can lower long-term energy costs.

Solar charging increases vehicle noise levels.

Solar charging requires large amounts of fossil fuels to operate.

Solar charging is illegal in most countries.

What is the role of the inverter in electric vehicles?

It converts DC from the battery into AC to power the electric motor.

It stores energy in the battery cells.

It converts AC to DC for the battery.

It changes gear ratios mechanically.

What is the Combined Charging System (CCS) in EVs?

A universal fast-charging standard that combines AC and DC charging in one plug, enabling high-power charging.

A specific lithium-ion battery chemistry used in EVs.

A government tax rebate program for EVs.

A regenerative braking subsystem.

What is a typical end-of-life use of EV batteries?

They are reused in stationary energy storage systems or recycled to recover materials like lithium and cobalt.

They are sent directly to landfills without processing.

They are converted into gasoline for reuse.

They are repurposed as replacement oil filters.

Select the two safety features found in EV charging cables.

Temperature sensors to prevent overheating

Locking mechanisms to avoid accidental disconnection

Decorative LED lights for aesthetics

Fragile housings to reduce weight

How does an ultra-capacitor support EV acceleration?

It releases energy quickly, providing a sudden power boost during acceleration and reducing load on the main battery

It slowly charges the main battery over long trips

It converts AC to DC for onboard electronics

It stores energy long-term to improve range by itself

Which option correctly identifies types of EVs and a key environmental and economic benefit?

Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Plug-in Hybrid Electric Vehicles (PHEV); lower tailpipe emissions and reduced fuel costs

Fuel Cell Vehicles (FCV) only; higher tailpipe emissions and increased fuel costs

Conventional ICE vehicles only; zero tailpipe emissions and reduced electricity costs

BEV and diesel hybrids only; increased maintenance costs and higher emissions

Which statement best summarizes EV batteries, their types, charging methods, and life considerations?

EV batteries are typically lithium‑ion variants; charging methods include Level 1, Level 2, and DC fast charging; lifespan is affected by temperature and depth of discharge

EV batteries are exclusively lead‑acid; charging is only possible with Level 1; lifespan is unaffected by usage patterns

EV batteries are disposable; DC fast charging is the only method; lifespan improves with frequent full discharges

EV batteries are nickel‑cadmium only; wireless charging is the primary method; lifespan is unrelated to heat

Which statement accurately characterizes ultra-capacitor charging, wireless charging, and solar charging in EV contexts?

Ultra-capacitors charge rapidly and deliver high power; wireless charging uses inductive coupling; solar charging uses photovoltaic panels to convert sunlight to electricity

Ultra-capacitors charge slowly; wireless charging requires a physical cable; solar charging relies on wind energy

Ultra-capacitors store large amounts of energy long-term; wireless charging depends on combustion; solar charging needs grid power

Ultra-capacitors cannot be recharged; wireless charging works only while driving at highway speeds; solar charging emits tailpipe gases

In a DC motor, torque is produced due to interaction between:

Electric field and magnetic field

Magnetic field and mechanical power

The rotor in an induction motor rotates due to:

Magnetic induction from the stator

In torque coupling, the engine and motor contribute to:

Different torque at different times

In speed coupling, the engine and motor:

Operate at different speeds but share load

What is the main advantage of Switched Reluctance Motor (SRM)?

Simple construction and ruggedness

What type of drive converter is used for SRM?

Inverter with asymmetric bridge converter

In SRM, torque is generated due to:

Magnetic attraction between stator and rotor poles
