Public Access EV Charging Infrastructure

Fueling The Electric Transportation Industry

Electric Infrastructure Workship | Tucson, AZ | January 21, 2009

Plug-In Vehicles Are Coming

BMW Mini-E: 2009

Toyota: 2009

Chevy Volt: 2010

Nissan: 2010

SMART: 2010

Mercedes: 2010

Major automakers will ship plug‐in cars in 2009

Creating A New Set Of Challenges

Where will people charge?There are only 54 Million private garages in the US for the 247 Million cars we haveStudies show that 80% of Plug-in owners want to charge more than once a dayThe result is that there are less than 12% of the needed charging points

How will the recurring costs, including the cost of electricity, be paid?Electricity for PIVs needs to be treated as a transportation fuelNeed ability to cover costNeed ability to generate revenueNeed ability to implement taxes

How will grid load be managed?Need ability to shed grid load during peak hoursNeed ability to manage charge times

NOTE: “Private lots” include condos, apartments, and corporate parking lots

People living in apartments and condominiums, or parking curbside or at work need a place to charge

Our Businesses

Charging Station RevenueLevel 1 (110V) and Level II (110V/220V) stationsUp to 220V/70A support in 2009Pole mount, wall mount, and bollard designs50%+ gross margins

Subscription Revenue80% of subscription revenue goes to station owner to pay for energy costs, maintenance costs, and station owner profit20% of subscription revenue pays for Coulomb network recurring costs

Charging stations sales are highly profitable ‐ subscriptions help drive charging station sales

Subscription & Networking Benefits

Subscriptions provide cash flow to hosts

Host BenefitsAllows hosts to cover costs  of electricity, taxes, maintenance, and capital payback

Provides host with revenue flow; similar to a coin operated laundry model

Eliminates energy theft (non‐subscribers cannot use Smartlets)

Greater public safety because Smartlet is de‐energized until user is authenticated, and cord is plugged in

Subscriber BenefitsInter‐utility and Inter‐service roaming gives drivers a nationwide charging network

Simple to use key fob / smart card system for authentication

Eliminates cord theft because cord is locked into place until same subscriber unlocks it.

Integrates with navigation system where available stations can be found and routed to subscriber’s navigation system

Networking also allows forImplementation of grid friendly programs (Demand Response Plans, Off‐Peak Plans, etc)

Remote Smartlet management (Firmware upgrades, remote GFCI resets, remote monitoring)

Automatic configuration through wireless network ‐installers do not need IT skills

New station viral networking ‐ stations can be requested through the web portal and routed to a the appropriate potential host.

Motivations and Value Propositions

MotivationsEnable economic benefits to drivers

Be more “green”

Reduce foreign oil dependence

Attract and retain tenants or employees

Create a business

Value PropositionsGenerate charging revenue – 80% of subscription revenue is returned to station owners

Manage grid load

Participate in “Cap and Trade” revenue flow

Attract and retain tenants/employees in apartments, condos, and office parks

Get LEED points to achieve various levels of certification

Use government subsidies for alternative fuel infrastructure

There are lots of reasons to own a networked charging

Competition Snapshot

Features in blue are best solved with networking

Business Flow

10

• We sell charging stations through regional and vertical distributors

• We sell our product to the distributors at a 35% discount

• Our distributors sell and perform installation and maintenance

• We sell subscriptions directly to drivers• Will provide free introductory subscriptions through auto dealers

• 80% of all charging revenue is returned to station owners to fund them for electricity, maintenance, and capital

• Cost to drivers targeted at half the cost of gasoline travel

Company Status

We are developing partnerships and relationships• Automakers, Utilities, Cities, Technology providers,

and Distributors• We are in dialogue with automakers about technical

specifications and rollout strategies• We are getting plenty of domestic and international

business “pull”

Production units shipped in 2008• San Jose Test and Demonstration Network now open

to the public• Small backorder for shipments in January

Series B will open in Q1

Profitable shipments in January

Barriers To Entry

Vision & Execution • Networked charging station system and all the features that it enables• World class team - experienced technology executives bringing networking technology to EV’s• We have the only networked charging station

Patents and Marks• 6 Patents either filed or in the process of filing and more on its way

“First Mover” Advantage• Recognized technology leadership has brought opportunities in new business segments (e.g. travel cords through

OEM supplier)• Sewing up key channels – we have signed agreements with key channel partners and continue to expand• More advanced software features and quality– will be hard for others to catch up (e.g. corporate fleet management

capabilities)• Early deployment in key regions – once network is in place with a host, as their need grows, they will grow with us• Subscriber base will build loyalty – giving us an advantage over new entrants• Leading the development of standards for interworking with other players and technology partners• Sewing up critical partnerships with grid technology providers, utilities, and networking partners
