Quarterly 

Reporting 

John Smart 

March 6 , 2013

Dissemination of Information 

The EV Project committed to provide quarterly 

reports to disseminate low-level summary 

information about: 

Project deployment status 

Plug-in electric vehicle driving and charging behavior 

Electric vehicle supply equipment (EVSE) usage and 

grid impact 

The quarterly reports provide a foundation to a 

much larger scope of work 

The EV Project will also be publishing white papers 

and technical reports to share lessons learned from 

infrastructure deployment and focused analyses of 

usage data

Quarterly Report Walk-through 

1. Overview report and maps 

2. Infrastructure usage summary report 

3. Nissan Leaf usage summary report 

4. Chevrolet Volt usage summary report 

Published to the following websites by the last day of the month 

following the quarter: 

www.theevproject.com/documents.php 

avt.inl.gov/evproject.shtml 

CSV files with underlying “plot points” are available at 

www.theevproject.com/documents.php

Overview Report 

Overview report provides at-a-glance 

project status update 

Number of EVSE installations and 

vehicle enrollments by EV Project 

market region 

High-level usage by region 

Maps show number of EVSE by type 

and vehicles by model in each EV 

Project market region

EVSE and Vehicle Usage Reports 

EVSE and vehicle behavior is studied from 

2 perspectives 

 

 

By monitoring stationary electric 

vehicle supply equipment (EVSE) as 

vehicles come to them 

By following vehicles as they travel 

between EVSE

EVSE and Vehicle Usage Reports 

Aggregation rules 

 

 

EV Project regions are broken out into separate sections if 

there are 10 or more EVSE or vehicles in a region 

EVSE types are broken out into separate sections if there are 

more than 10 EVSE of the same type 

Residential 

Private non-residential 

Public level 2 

Public DC fast charger

Infrastructure Usage Summary Report 

 

 

 

Provides aggregate metrics 

and distributions for EVSE 

usage by type, charging level, 

and region 

120 pages and counting 

Answers the questions 

Who… uses them? 

What… kind are they? 

When… are they used? 

Where… are they located? 

How… much, how often are 

they used?

Infrastructure Report cont. 

Up to 9 pages for each region and nation

and as distributions by day of week

Vehicle Usage Summary Reports 

Nissan Leaf and Chevrolet Volt Usage 

Summary Reports provide aggregate 

metrics and distributions by region and 

nationally 

Answer the question: 

How do drivers use infrastructure 

relative to how they drive to 

achieve their desired results?

Vehicle Usage Summary Reports 

Nissan Leaf and Chevrolet Volt Usage 

Summary Reports provide aggregate 

metrics and distributions by region and 

nationally 

Answer the question: 

 

 

 

 

 

 

Where… are they charging? 

When… are they charged relative to battery 

pack state of charge? 

How much and how often… driving? 

How much and how often… charging? 

How complete is the charging? 

How much… Volt driving in electric-only 

mode as a result of the driving/charging mix

Nissan Leaf Usage Summary Report 

One page for each region and nation 

How much and how often driving 

and charging? 

Per trip, per day, per charge 

 

Where charging?

Nissan Leaf Report cont. 

For each region and nationally 

When charging with respect to battery pack state of charge? 

How empty is the pack at the start of charging? 

How full is the pack at the end of charging?

Chevrolet Volt Usage Summary Report 

One page for each region and nation 

How much driving and charging 

and how often? 

 

How much gas vs. electricity? 

Where charging?

Chevrolet Volt Report cont. 

For each region and nationally 

When charging with respect to battery pack state of charge? 

How empty is the pack at the start of charging? 

How full is the pack at the end of charging?

Chevrolet Volt Report cont. 

Coming soon for Volt report: 

 

 

Percent of miles traveled in EV-only versus extended-range 

mode 

Percent of charging events at level 1 versus level 2 charge rate 

Remember quarterly reports are summaries 

Must be automatable and robust to changes as project evolves 

Look to white papers and technical reports for additional 

answers to your burning questions

What “understanding” can be reported? 

How will this add to the body of knowledge?

INPUT for EV Project Observations 

I. The EV Project Quarterly Reports 

 

 

 

Aggregates major data collection categories 

Provides significant quantities of information by region, vehicle type, EVSE 

type, etc. 

Plots and Graphs aid understanding 

 

 

II. Experience 

 

 

 

Planning Process 

Deployment Activities 

Installation Work 

III. Data Analytics 

 

 

 

Observing Data/Information 

Searching data for answers to questions 

Asking questions and experimentation


Observations on Quarterly Reports 

Fast Facts – Through 4th Qtr 2012 

 

 

 

 

 

 

Nearly 60 million miles recorded on EV 

Project vehicles to date 

Over 1.6 million charging events 

recorded to date 

Over 14,100 Megawatt hours of energy 

delivered to Project vehicles thus far 

7,376 Nissan Leafs, Chevrolet Volts and 

Smart ForTwo vehicles participating 

Over 1.9 million gallons of gasoline 

avoided by EV Project vehicles to date 

Nearly 4500 metric Tons CO 2 e avoided


Observations on Vehicle Utilization 

 

Typical Questions: 

 

 

How do Project participants use their vehicles? 

How does usage vary between Leaf and Volt?



 

How can trip end points tell us infrastructure needs? (Compare against participant’s 

reported desires, view SOC at end of trip, distance traveled to get there, etc.) 

San Diego Leaf Trip End Points



Do drivers program their EVSE, their vehicle, both or neither? 

No Program 

Vehicle Program 

EVSE Program 

Both Programmed


Observations on Charge Infrastructure Utilization 

 

 

What are the best venues for public infrastructure? What is the metric 

for “best”? Utilization in time connected, connect events, kWh 

dispensed, location? 

How do Car Sharing programs affect public infrastructure utilization?


Observations on Charge Infrastructure Utilization 

 

When, where, how often are participants using the public infrastructure? 

Fraction by owner 

Highest number of charge events


Observations on Infrastructure Operational Impacts 

 

 

What are potential load impacts on electric utilities? 

What are the downsides for hosts in providing public infrastructure?

Residential Publicly Accessible AC Level 2 DCFC


Observations on Infrastructure Operational Impacts 

 

Data Summary 

How can Charging Site Hosts benefit from public infrastructure? 

Currently have 15 locations with a total of 29 L2 chargers. 

Total of 2,033 charge events occurred from 377 different Member Numbers (Consumers) over a 10 month period. 

On a per month basis this data would equate to 203 charge events from 37 different 

Member Numbers (Consumers) that connected 5.59 times per month. 

Total of 6,490.86 kwh were dispensed at the chargers. The Avg charge event was 3.19 kwh 

Avg. connection time was 1 hr and 12 min

Observations on Infrastructure Deployment Issues 

 

Typical Questions 

 

 

How will the final 

infrastructure deployment 

compare to the EV Micro- 

Climate plan? What 

difficulties were 

encountered in trying to 

meet the plan? 

Installation costs by labor, 

materials, taxes, permits?


Observations on Infrastructure Deployment Issues 

 

 

How does lack of national guidance on ADA compliance affect 

installations? 

What challenges are encountered with a lack of signage standardization?


 

 

 

 

What effects may be anticipated by 

the maturing EV Infrastructure?
