An introduction to EVs EV School presents: An introduction to EVs EV School 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
EVs compared to normal cars Electric vehiclesNormal cars Energy comes fromelectricityfossil fuels Where Energy is storedrechargeable batteriespetrol tank Engine typeelectric motorinternal combustion engine Where the energy is put in power outlet and charging cord petrol cap Are there anytail-pipe emissions? noyes
What does an EV look and sound like? Looks like a normal car Sounds silent when running as has less moving parts
Normal cars produce greenhouse gases
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 km between charges Charging can take hours Silent operation – potentially dangerous for pedestrians
Discuss Why do you think more people arent driving EVs? Would you drive an EV when youre older? Why? Why not?
