1. Cellular Networks forEV & Charging Infrastructure Integration Andy Wood Qualcomm

3. FORTUNE 500 company

4. Developed CDMA, foundation of 3G cellular networks

5. #1 wireless semiconductor firm

6. 16,000+ employees

7. 100+ offices in 22 countries

8. Headquarters in San Diego, CARevenues FY09 $10.4 billion

9. EVs & Charging Infrastructure require connectivity Remote control & diagnostics Vehicle & user authentication Locate and reserve charging points Billing and payment Load control and demand response Ancillary services

10. Key players relying on commercial cellular networks Examples: Nissan GM ECOtality Coulomb Better Place Why are the EV innovators choosing cellular?

11. Reason #1 : Mobility Electric Vehicles are mobile nodes in the Smart Grid 1011101010001010110 010011011010101010

12. 96% U.S. population covered by mobile broadband* 99% non-rural coverage* - good match with expected EV clusters Available now, very flexible in terms of EV location and scale Multi-mode / mix & match systems to take advantage of various carriers & technologies 96% Total pops 99% Non-rural pops Reason #2 : Coverage & Availability * FCC estimates; “Bringing Broadband to Rural America”; May 2009

13. Reason #3 : Standards-based Well established standard bodies 3rd Generation Partnership Project (3GPP) GSM, UMTS, LTE 3rd Generation Partnership Project 2 (3GPP2) 1xRTT, EV-DO (Rev. 0 / A / B) Specifications available at www.3GPP.org and www.3GPP2.org

14. Reason #4 : Real-Time Communications Readiness for integration in advanced Smart Grid tasks 2.5G 2.75G 3G UMTS 3G EVDO Source: ISO/RTO Council; “Assessment of Plug-in Electric Vehicle Integration with ISO/RTO Systems” March 2010 End-to-End Average Ping Time (RTT1) Between Network Nodes Performance is based on empirical measurements from commercially available systems. Source: CDMA Development Group; “Mobile Broadband Comparison”; March 2008

15. Reason #5 : Multi-mode Flexibility 2G 4G 3G Coverage Module cost Connectivity cost Latency Throughput Lifecycle 9

16. Concern #1 : Connectivity Cost Key factors: scale, network utilization, carrier relationship Source: SmartSynch webinar in June 9, 2010 http://energycentral.fileburst.com/Product_webcasts/20100609_Cellular_Smart_Grid_SSI.swf

17. Concern #2 : Reliability & Security As any network – not 100% invulnerable, end-to-end security architecture approach required Managed nature address control & privacy issues Passed tests of: Scale (4 ~ 5 billion subs) Time (decades in operation) Users (financial sector, U.S. president)

18. Takeaways Cellular to play key role in EV ecosystem Mobility Coverage Standards-based Real-time Communications Multi-mode flexibility 3G presents advantages over 2G, multi-mode / mix & match aggregate benefits from both Concerns exists, but can be addressed with right architecture and business approaches
