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


Key players relying on commercial cellular

networks

Examples:

• Nissan

• GM

• ECOtality

• Coulomb

• Better Place

Why are the EV innovators choosing cellular?


Reason #1 : Mobility

Electric Vehicles are mobile nodes in the Smart Grid


96% U.S. population covered by mobile broadband*

Reason #2 : Coverage & Availability

• 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

* FCC estimates; “Bringing Broadband to Rural America”; May 2009


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

Reason #4 : Real-Time Communications

Readiness for integration in advanced Smart Grid tasks

End-to-End Average Ping Time (RTT1) Between Network Nodes

Performance is based on empirical measurements from commercially

available systems.

Concern #1 : Connectivity Cost

Key factors: scale, network utilization, carrier relationship

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)


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
