Electric Vehicles

Globally, electric vehicles are almost universally being supported by governments
& communities…



                                       Environmentally Friendly
                                              Energy Efficient
                                         No roadside emissions
                                                     Quiet




                                                                                2

Hong Kong Government has expressed their support for electric vehicles


 Announced support for Electric Vehicles in Budget
 Speech (Feb 2009)
 Extension of waiver of 1st registration tax for EVs
 Subsidies for electric public light buses

 Specifically cited “infrastructure/charging” as a
 key enabler

 including property developers and private car park
 operators, to set up such facilities

EV Infrastructure Development Across the World

Regional differences in environment (regulatory, social, economic) are driving
different solutions for clean transportation infrastructure


EV infrastructure in other countries…

 Small scale EV charging networks implemented as
 a partnership between solution providers, the
 municipality and/or the utilities

 San Francisco, London, Paris, Tokyo, Norway

 Most are done as community service and on a
 voluntary basis

 However, in Vancouver, Canada – regulatory
 requirement recently passed for mandatory
 charging points in multi-family buildings


                                                                                 5

                  Electric Vehicle : Penetration Rates

                    Many governments have announced
                    EV targets

                    China: 10% “new energy vehicles” by
                    2012
                    London: 5% by 2015
   Other            Ireland: 10% by 2020
 Countries          Vancouver: mandatory 20% charge
                    spots in car parks

                    No targets set by
                    government so far

                    Charging solution must be
                    flexible and scaleable

Charging Standards


       Electric Vehicle Charging Standards are beginning to take shape

Types of Charging: shaped by how much time for / frequency of charging


      For private cars, charging will be shaped by how much time they have

Hong Kong environment is unique which calls for a slightly different approach…


        For Hong Kong, a viable charging infrastructure will have to be….

          Oriented towards car parks – both
          public and private

          Compact and space-efficient

          Easy and inexpensive to install

          Scaleable

          “Right” type of charging for the “right”
          places and applications

          Easy to use and understand



                                                                             13

“You got to start somewhere…”


 Electric Vehicle Charging Infrastructure Trial Project

   18 May 2009 - MOUs with the LINK and Wilson
   Parking

   Collaborate in a pilot project - develop and
   facilitate EV charging spots in public car parks

   The trial project is expected for 5 years

   At least 10 car parks in the first 12 months




       First electric vehicle charging infrastructure for public use of this scale

                                                                                     15

“You got to start somewhere…”


 Electric Vehicle Charging Infrastructure Trial Project

   CLP to design & install charging
   spots, partners to provide facilities
   and day-to-day security & support

   Initially focused on public car parks
   but will be extended in phases to
   private car parks

   EV Charging network design is
   scaleable - can be continuously
   expanded & improved

Objectives of the trial charging infrastructure…


What we hope to do…
