ELECTRIC VEHICLE

Definition of Electric Vehicles

How Does a PHEV Work? PHEVs overcome the range

problem of BEVs Electric-only range vary with

battery size

PHEV20 = 20 miles range PHEV40 = 40 miles range PHEVs well suited for our dailydriving patterns 50% of all daily drives <25 miles 80% of all daily drives <50 miles Average daily driving=33 miles

Battery5-15kWh

Hybrids vs. EVsElectric Vehicles (EVs)• Large battery pack:– Expensive – Limited range– Uncertain life

• Pure electric drivetrain+ Excellent energy

efficiency + Independence from oil

Hybrids (HEVs)• Minimised battery

pack+ Cheaper + Long range+Manageable lifetime

• ICE based drivetrain– Incremental efficiency

gain – 100% dependant on

oil

Reasons for Considering an Electric Vehicle

Lowest total cost of ownership today

Excellent performance

Good for the environment

Good for national security

Good for the electricity gridEVs Improve the Utilization of the Grid to Achievehigher Economic Efficiency

It offers “cool” technology and it will be part of our future

Components of the V2G system

Services V2G can offer

• Frequency regulation: Contingency– 6 sec– 60 sec – 5 min

• Voltage Regulation

• Recloser ride-thru

GUIDE TO ANCILLARY SERVICES IN THE NEM pdf

Services V2G can offer

• Note that the V2G services are usually about the provision of instantaneous real and reactive power as a service

• NOT about the supply of energy• Battery pack capacity usually limits the peak

shaving / load levelling capability• Some hybrids can start Internal combustion

engine and generate – but of limited value

Disadvantages of Plug In Electric Vehicles

1.Cost of batteries and ownership2.Availability of recharging infrastructure3.Potential overload of the electric grid4.Risk of battery life5.Plug-ins will crash the electrical grid.
