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
