Electric Transportation Arriving Soon
Over
70%
of auto makers*
are introducing
plug-in vehicles
*by market share

Establishing a Smart Grid Infrastructure for EVs
Smart Charging:
 Manages the one-way flow of energy
 Allows drivers to set parameters
 Balances grid & driver needs
via sophisticated software
 Enables adaptive management:
- Delay/slow during peak demand
-
Increase with availability of
renewable energy
Plug-In Vehicles
Grid Distribution System
 Connecting to the grid in 2010
 Charging management technology
 Many rollouts call for 240V/L2
wall mounted garage chargers
 Adoption likely clustered in
neighborhoods
is required*
 Capacity exists for wide EV adoption*
 A few EVs, clustered & charging
at peak, could impact reliability

 Enhances reliability
 Increases renewable integration
 Delivers control of a valuable asset
– load, storage & generation
VEHICLE OWNERS:
Smart
Charging
 Reduces total cost of EV
ownership
 Enhances ability to drive “green”
Auto Manufacturers:
 Drives sales
 Creates a supportive EV ecosystem

One Example of Value—Smart Charging Used to
Increase Renewable Integration
Smart Charging Management Opportunities
Load Shifting
Load Shaping
Time based management shifts charging behavior into
non-peak periods
Demand valleys can be filled by scheduling charging
around a central time
Load Shaping
Following an signal or schedule, charging load can be
dynamically shaped according to grid needs
Renewable Integration
Based on a live wind or solar signal, charging can be
synchronized with the availability of renewable energy
Spinning Reserves
The flow of energy can be rapidly slowed or stopped, creating
capacity in response to an unexpected power disruption
Economic Dispatch
Following a real-time price signal allows energy economics to
determine charging behavior
Economic Dispatch
State of the Art Performance Data Logging
Used by Idaho National Laboratory, the same client-server solution that enables
smart charging delivers robust performance capture
Advanced Analysis
Supports complex performance evaluation, including MPG, fuel
& energy consumption, charging data, etc.
Improved Performance Data
Data is automatically logged & securely uploaded, increasing
reliability & enabling real-time evaluation
Increased Flexibility
Multiple methods of intra-vehicle & client/server
communication are supported
Remote software updates
Staff involvement in data collection & administration is
minimized with remote support & configuration
Enduring Investment
A second software license is all that's required to explore
smart charging, no additional hardware is necessary
Smart Charging Demonstration
Proprietary & Confidential
Preparing for Plug-Ins: What You Can Do
Smart charging demonstrations are opportunities to:

Assess the importance of controlling vehicle load at the distribution level

Explore various charging scenarios, including load shaping & peak shaving

Investigate synchronizing charging with wind or solar power

Gain experience enlisting participation in smart charging programs

Determine system requirements surrounding service area “roaming”

Establish the benefits of electric vehicles, confirming efficiency, decreased
fuel costs, reductions in green-house gas emissions, etc.
How are you preparing for plug-ins?
