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.

• 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).
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)
