1、An Brief Introduction ToSpeechmaker: Lei LuoMembers: Xin Chen Yeyu Chen Meidi Sun Zhewen He Wei WangWhat is an electric vehicle? We run on electricity！We have three types of Evs:Hybrid Electric Vehicles (HEVs): petrol engine + battery (never plugged in) Plug-in Hybrid: petrol engine + electric motor

2、 (plugged in) Full Electric: electric motor + battery (plugged in) What does an EV look and sound like?Looks like a normal carSounds silent when running as has less moving partsHow do we work?How to work? Use electricity not petrol Energy comes from a power outlet via a cord to the car Energy stored

3、 in a battery Energy powers the electric motor, moving the car.Regenerative Braking Captures the energy from braking, normally lost as heat Uses it to top up the batteryBetter for the environment produce 27 per cent less Carbon dioxide than petrol cars help to reduce greenhouse gas emissions Produce

4、 no carbon emissions when powered using renewable energy cheaper to run because electricity is cheaper than petrol better for the environment reduce noise pollution less environmental impacts across their life-cycle (manufacture, use and disposal)Benefits of electric vehiclesComparison: TESLA & BYDT
