Introduction to Electric Cars

A key benefit of electric cars is that they (a)  

• They are faster
• They produce zero emissions
• They are cheaper to maintain
• They have longer ranges

The harmful effect of gasoline cars highlighted is (a)  

• Water pollution
• Carbon dioxide emissions
• Excessive tire wear
• Noise pollution

What is a key advantage of electric motors over gasoline engines?

• They are more complex

• They generate more heat

• They are simpler and more efficient

• They require more maintenance

What stores the energy in an electric car?

• Engine

• Transmission

• Battery

• Exhaust

Match the following functions with their descriptions:

• Regenerative braking

• Reduces the car's speed without using brakes

• Engine braking

• Cools the brakes

• Brake cooling system

• Charges the battery while braking

• Acceleration

• Increases speed while braking

One environmental benefit of electric cars is that they (a)  

• They use solar energy
• They don't release exhaust gases
• They reduce water pollution

A challenge of electric cars is that (a)  

• They are too noisy

• They are difficult to operate

• There aren’t enough charging stations

Electric cars are more expensive because (a)  

• They have expensive tires
• Batteries are costly
• They need frequent repairs
• They use more resources to make

What helps with “range anxiety”?

• Bigger batteries

• More fast-charging stations

• Lower car speeds

• More solar-powered cars

How long does it take to charge an electric car at home?

• 30 minutes

• 2-4 hours

• 8-12 hours

• 24 hours
