Uses electric motors for propulsion.

For more detail refer page 3

Types of EVs?• Hybrid Electric Vehicles (HEVs):

petrol engine + battery (never plugged in)(e.g. Honda Civic).

• Plug-in Hybrid: petrol engine + electric motor (plugged in)(e.g. VW X1).

• Full Electric: electric motor + battery (plugged in)(e.g. Mahindra E20).

How do they work?• Use electricity not petrol• Energy comes from a power outlet via a cord to the

car• Energy stored in a battery• Energy powers the electric motor, moving the car.

EVs compared to normal cars

Electric vehicles Normal cars

Energy comes from electricity fossil fuels

Where Energy is stored rechargeable batteries petrol tank

Engine type electric motor internal combustion engine

Where the energy is put in

power outlet and charging cord

petrol cap

Are there any ‘tail-pipe’ emissions?

no yes

What does an EV look and sound like?

Looks like a normal car

Sounds silent when running as has less moving parts

Are EVs better for the environment?• Produce 27 per cent less CO2 than petrol cars• Help to reduce greenhouse gas emissions• Produce no carbon emissions when powered using

renewable energy

Benefits of electric vehicles?• Cheaper to run because electricity is cheaper than petrol• Better for the environment• Reduce noise pollution• Less environmental impacts across their life-cycle

(manufacturing, use and disposal)

What are some disadvantages of EVs?• Currently more expensive than normal cars• Not many places to charge your car• Can only travel 100-160km between charges• Charging can take hours• Silent operation – potentially dangerous for

pedestrians
