4. Some hard questions and a
few facts …

5. Electric Vehicle: an energy nightmare ?
One can hear a lot of nightmarish predictions…
● « EV charge will create black out… »
● « … or force to use massively fossil electricity »
● « Need to build many new power plants to charge the millions of EVs »
● « massive investment is necessary to build the infrastructure »
● « domestic installations will not support electric vehicle… »

6. Could mass scale deployment of Electric
Vehicles threaten the grid in term of power ?
● Power needed for E.V could add to peak, leading to more use of fossil
energy at peak time.
● 2M EV charging simultaneously = 8 GW (normal charge) upto 80 GW (if
all fast charge)
● Installed power
● 100 GW in France
● 1000 GW in China
Massive charge at peak time is not acceptable

7. However energy is not a critical problem
● France annual consumption about 500 TWh
● China annual consumption about 4000 TWh
● 1 EV = 17000 km / year = 2 MWh
● With 2 M EV
● Energy needed = 4 TWh (< 1% total in France, 1° ° for China)
/ °
● Renewables (2020 vision)
● Wind : 25 GW, 60 TWh / y in France, 15 times total EV consumption
● Wind : 150 GW, 350 TWh / y in China
● Several TWh over capacity at some times (night production may exceed
demand)

8. What are the solutions to
manage energy for Evs ?

9. Charging mode provide the technical answer
● Managed charge will limit peak demand and open new services for very
efficient energy management. It is a breakthrough innovation for the grid.

10. Charging to be managed at all levels
● At Charge station level
● Local user interface
● Multi spots management
● At Local level (home / building)
● Loads management
● Day/night, loadshedding systems
● At Grid level
● Tariff incentives, through smart meter
● Demand / Response
● V2H, V2G in the future

17. As a conclusion
● Grid can support EVs in the initial years.
● It is essential to start immediately with load management, to have the
capability to avoid higher peaks in demands.
● Energy management must be part of home and building energy
management, for highest effectiveness
● As EV number grows, grid will get a « no cost », flexible storage
capacity for Demand / Response management.
● Storage, and later V2G, will help Renewal energy increase on the grid.
