Electric Vehicle Recap Questions

What is one feature all electric cars share?

• They have no internal combustion engine (ICE).

• They have a dual exhaust system.

• They require petrol to operate.

• They rely solely on hydrogen fuel cells.

A hybrid vehicle typically includes:

• Only an internal combustion engine.

• A drive traction motor and an engine.

• Only a battery and an electric motor.

• A fuel cell and a high-pressure hydrogen tank.

What is unique about a PHEV type hybrid compared to a self-charge hybrid?

• It requires a battery flap and a petrol flap.

• It does not require a petrol flap.

• It only charges through regenerative braking.

• It uses only an internal combustion engine.

What precaution should be taken before using charging cables?

• Ensure the battery is fully discharged.

• Check that all cables and connections are dry.

• Use a gasoline-powered generator first.

• Remove the battery from the vehicle.

What are the two basic components of the traction electric motor?

• A. A rotor and a high-pressure pump.

• B. A spinning rotor and a 3-phase stator winding.

• C. A stator winding and an exhaust system.

• D. A rotor and a hydrogen fuel cell.

What type of charger combines fast DC charging and AC 7kW?

• Type 1 charger.

• Combined Type 2 charger.

• Single-phase charger.

• Level 1 home charger.

What powers the air conditioning compressor in hybrid and electric vehicles?

• Low-voltage circuits.

• The internal combustion engine.

• High-voltage systems.

• A hydrogen fuel cell.

What does the green EV ready display lamp indicate?

• The battery is fully charged.

• The vehicle is switched on and ready to run.

• The charging cable is properly connected.

• Maintenance is required.

What is a potential hazard of high-power permanent magnets used in motors?

• They generate excessive heat.

• They interfere with devices like pacemakers.

• They can cause short circuits in the battery.

• They emit harmful gases.

How does a hydrogen vehicle generate electricity?

• By burning hydrogen in an ICE.

• By mixing hydrogen and oxygen in a fuel cell.

• Through solar panels on the vehicle’s surface.

• By using hydrogen to spin a rotor.
