Over

70%of auto makers*

are introducing plug-in vehicles

*by market share

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

Establishing a Smart Grid Infrastructure for EVs

Plug-In Vehicles

Connecting to the grid in 2010

Many rollouts call for 240V/L2 wall mounted garage chargers

Adoption likely clustered in neighborhoods

Grid Distribution System

Charging management technologyis required*

Capacity exists for wide EV adoption*

A few EVs, clustered & charging at peak, could impact reliability

Creating a Reinforcing Cycle of Benefits

Smart Charging

UTILITIES: Delays infrastructure investments

Enhances reliability

Increases renewable integration

VEHICLE OWNERS: Reduces total cost of EV

ownership

Enhances ability to drive “green”

Auto Manufacturers: Drives sales

Creates a supportive EV ecosystem

Delivers control of a valuable asset – load, storage & generation

Smart Charging Used to Shape Vehicle Load

Load ShiftingTime based management shifts charging behavior intonon-peak periods

Demand valleys can be filled by scheduling charging around a central time

Renewable IntegrationBased on a live wind or solar signal, charging can be synchronized with the availability of renewable energy

System Regulation Following an AGC signal, the charging load can be dynamically increase or reduced according to grid needs.

Spinning ReservesThe flow of energy can be rapidly slowed or stopped, creating capacity in response to an unexpected power disruption

Economic DispatchFollowing a real-time price signal allows energy economics to determine charging behavior

Load ShapingFollowing an signal or schedule, charging load can be dynamically shaped according to grid needs

Smart Charging Management OpportunitiesLoad Shaping

Preparing for Plug-Ins: What You Can Do

Better understand the power of smart charging

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

Acquire valuable learning, critical to strategic planning

Gain experience enlisting participation in smart charging programs

Determine system requirements surrounding service area “roaming”

Acquire relevant learning to inform utility, PUC and regulator decision making on EV-related rate schedules

Confirm the value of electric transportation

Establish the benefits of electric vehicles, confirming efficiency, decreased fuel costs, reductions in green-house gas emissions, etc.
