EV presents:

What is an
electric vehicle (EV?)

A car that runs on electricity

Types of EVs?

Hybrid Electric Vehicles (HEVs):
petrol engine + battery (never plugged in).

Plug-in Hybrid: petrol engine + electric motor (plugged in).

Full Electric: electric motor + battery (plugged in).

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.

What is Regenerative Braking?

Captures the energy from braking, normally lost as heat

Uses it to top up the battery

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
