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
Good for the electricity gridEVs Improve the Utilization of the Grid to Achievehigher Economic Efficiency
Services V2G can offer
• Frequency regulation: Contingency– 6 sec– 60 sec – 5 min
• Voltage Regulation
• Recloser ride-thru

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.
