Level 2 Usage Study Webinar – February 18, 2016

This webinar discussed the Level 2 Charging Station Usage Study methodology and results. In 2015, the NC PEV Taskforce completed a statewide assessment of public electric vehicle charging station usage and management. The study focused specifically on Level 2 charging stations, with the objectives to develop public charging station usage benchmarks for North Carolina, identify factors affecting station usage, and highlight best practices for charging station management.

Questions & Answers
1. Where was the usage data sourced?  The data was individually gathered from the sites.
2. What is the most important finding the study elucidated? We think the most important part was setting a benchmark for further studies. It was also very interesting to see why stations were being used more or less.
3. What type of amperes are most of the Level 2 charging stations?
Most Level 2 public stations are rated at 30 amps of electric current, which requires a circuit rated for 40 amps.
4. Level 1 charging wasn’t considered? Why not? Level 1 is becoming a common type of charging seen around the state, however the usage data is hard to collect, so we did not include it in the study.
5. You mentioned that a fee for plug-in reduced usage. Do you have any information on determining optimal fee.
Information on optimal fees is limited. Almost all of the public stations in North Carolina that assess fees for Level 2 charging are part of the ChargePoint network, which allows the owner to determine the fee.  Based on information from PlugShare and our Owner Survey, fees at these sites ranged from $1 to $2 per hour.  At some sites the cost of charging was $1.25 for the first hour and $2 for every hour of charging thereafter.  These fees are similar to those seen in other areas of the United States I would refer those looking on for information on fees to the August 2015 “Paying for Juice” webinar hosted by the PEVC.  The presentations by PEVC and Chargepoint were especially informative. Research from the EV Project is also available, but the market may be evolving too quickly for that to be useful.  I am not aware of many other resources on fees for charging. http://www.pevcollaborative.org/webinars
6. It looked like on-street parking was the highest use of EV charging. I have heard there are some concerns about on-street parking EVSE….are the owners of those on-street spaces generally satisfied with them? Are you expecting this to lead to more on-street parking EVSE? This study did not look specifically at that, but we have noticed that taking away on-street parking can be difficult. However, on street charging stations are usually highly used because of their visibility.

7. Did you collect any data from owners of non-networked chargers? Yes, we collected a lot of data from non-networked chargers and networked chargers.
8. What’s the best place to go for grants or public funding mechanisms? There is currently funding available through the CFAT program. Here is a link for more information https://nccleantech.ncsu.edu/clean-transportation/clean-transportation-projects/clean-fuel-advanced-technology-project/
9. The DOE’s workplace charging challenge survey results show that employees that are offered EV charging are 20x more likely to drive an EV. Wouldn’t workplace be a better use of funding rather than public? You are correct that the availability of workplace charging greatly increases the likelihood of someone purchasing an EV. For this project, however, our funder specifically wanted to look at public charging to better understand how the stations are being used and managed. The goals of the study were to develop benchmarks for public charging in North Carolina, identify factors affecting usage, profile station management and highlight best practices. The only study completed similar to this one was through the national EV Project, which did not include North Carolina. This study allowed us to better understand public charging in our state. Also, from 2012 to 2014, we did conduct a workplace charging usage study. For more information on that study, please visit http://www.advancedenergy.org/2015/07/08/article-masthead/.

Brevard College Offers Charging Stations

FROM: Brevard College
CONTACT: Elizabeth Harrison, 828.884.8115,
SUBJECT: Brevard College teams up with Tesla Motors: Tesla Destination Charging now offered on campus
BREVARD – Brevard College has teamed up with Tesla Motors to provide an increasingly desirable amenity to the Brevard community: Tesla Destination Charging. The College will unveil one of its two Tesla Electric Vehicle charging stations on Monday, Oct. 26, at 11:30 a.m. at its official ribbon-cutting ceremony.

Brevard College is now the first College or University in the U.S. to offer Tesla High-Speed High-Power Wall Connector and standard J1772 units for free public-access Electric Vehicle charging and is the first location in Transylvania County to offer EV charging stations. Tesla High Power Wall Connectors add 58 miles of range per hour to Model S, charging the vehicle overnight and replicating the convenience Tesla owners are accustomed to at home.

“Brevard College is constantly finding new ways to reduce our carbon footprint,” said BC President David Joyce. “By combining leading-edge technology and the forward-thinking of Tesla with our commitment to being a leader for higher education in the environmental movement, we now have the ability to offer the Brevard community a seamless and convenient charging experience.”

The College joins a rapidly growing network in Tesla’s Destination Charging Program. Tesla partners with hotels, resorts, colleges and universities around the world to offer High Power Connectors. Model S offers 270 miles of range on a single charge so the High Power Wall Connector can easily top off the Tesla in just a few hours.

Brevard College will soon be hosted along with other Tesla Destination Charging locations on Tesla’s interactive webpage and will be GPS located on Model S navigation through a free software update sent wirelessly to the car. Tesla owners will be able to use the Model S 17” touchscreen to easily plan trips and locate the chargers at the College.

Tesla Motors’ (NASDAQ: TSLA) goal is to accelerate the world’s transition to sustainable transport with a full range of increasingly affordable electric cars. California-based Tesla designs and manufactures electric vehicles, as well as renewable energy storage. Tesla has delivered more than 90,000 electric vehicles to customers worldwide.

Brevard College is committed to an experiential liberal arts education that encourages personal growth and inspires artistic, intellectual, and social action.

Good Will Charging

Good Will Charging

Contrary to reports of “charger rage” that have received media coverage, electric vehicle charging can be a model of cooperation. That was the take-away message from the California Plug-In Electric Vehicle Collaborative’s October webinar, Taking Turns: How to Effectively Share Electric Vehicle Chargers. The webinar lived up to its title by highlighting successful programs and solutions that allow EV changing to go smoothly. The value of policy, training, driver engagement, and good communications emerged as common themes.

Formulating the Rules

“Many companies have formal policies,” said Kristi Brodd of Advanced Energy. “These are great at setting ground rules and keeping charging moving smoothly.” Kristi was fresh from surveying California companies about how they handle charging. Her work feeds into a new guidebook, Plugging in at Work: How to Effectively Install, Share, and Manage Electric Vehicle Charging Stations. The guidebook will soon be available on the PEV Collaborative’s website.

Fleet, transportation, and facilities departments collaborated at San Diego Gas & Electric to create a formal policy. “We ask that EV-driving employees participate in a training program so they understand the philosophy behind the charging policy and the dos and don’ts for using the facilities,” said Greg Haddow of SDG&E. The program currently has 158 chargers spread between 18 sites, serving an EV fleet of 30, as well as 185 EV-driving employees.

Justina Hyland of Adobe presented a model of an informal policy that is managed by the company’s EV community, which currently consists of more than 100 drivers sharing 47 dedicated charging spaces. “Every quarter, all the EV drivers meet and govern themselves. The rules of etiquette were developed by the team based on our experiences with charging. EV drivers are motivated to be responsible so that others will be responsible because they all have a vested interest in sharing this resource.”

Lisa Chiladakis of the PEV Collaborative and moderator Chris White of BKi discussed PEV charging in a City of Sacramento-owned public parking garage, which does not have a formal policy. However, regular users have an agreement in place for how to manage the 20 Level 2 chargers, which serve about 100 EVs.

Engagement and Management

The panelists discussed the role of communications in helping EV drivers understand and maintain charging etiquette. Flyers, dashboard placards, courtesy cards, email distribution lists, signs, websites, intranets, and EV groups serve to keep drivers informed of the rules and program updates, as well as help them manage the logistics of charging.

“It becomes routine for drivers to respect others schedules,” Greg observed. SDG&E’s dashboard cards let drivers know at what time a vehicle can be unplugged. Emails inform users not only about rules but alert them to periods of congestion so they can adjust their plans. “We find that a frequently used email communication helps a lot. We view employee education to be the most important thing, and we welcome having employees tell us their ideas and concerns.” SDG&E also has facilities staff who monitor EV charging and issue warnings when rules aren’t followed.

Abode uses emails and texts to alert drivers when their charging is complete. “We have an active EV community. If drivers aren’t obeying the rules, they are called out about it. They police themselves,” Justina noted.

At the Sacramento’s public parking garage, rules and etiquette are communicated with a flyer. Additionally, the city’s parking garage website hosts a drivers’ group, which users are encouraged to join. The EV parking spaces are all marked for active charging, and this policy is enforced through parking violations.

The webinar concluded with the panelists offering advice on EV charging. Greg emphasized the importance of surveying employees and designing a program around their needs. Justina recommended ongoing monitoring and having the flexibility to grow and adapt. Kristi recommended being proactive about creating a policy in order to have rules in place should problems arise.

A Profusion of Solutions for EV Charging

Article provided by the California Plug-in Electric Vehicle Collaborative.

A Profusion of Solutions for EV Charging
“Build in flexibility and the capability to grow,” said Rachel Moses of Greenlots, during
the Plug-In Electric Vehicle Collaborative’s August webinar Paying for the Juice. Her
advice was echoed by other electric vehicle charging equipment and network providers
who discussed ways to structure and manage electric vehicle charging.

Payment and billing options included point-of-sale credit card swipe; payment via mobile app; phone customer service; radio-frequency ID devices such as employee badges; homeowners association parking fees; payroll deductions for workplace charging; and driver or site host’s utility bill.

Lyuba Wolf of ChargePoint noted that owners of charging stations could use pricing to
achieve different goals:
• Free – helps attract and retain employees and customers
• Charge for Charging ($/kWh) – allows owners to be reimbursed for electricity costs
• Charge for Parking ($/hr) – encourages drivers to move their vehicles when done
• Taxi Pricing (tiered pricing where rates increase after a set number of hours) –
really encourages people to move when charging is complete. For example
someone may pay $1/hour for the first 4 hours and then $5/hour after that.

ChargePoint sells charging station hardware that is “networked” allowing the owner of
the station (site-host) to monitor the use of the station and set pricing that is paid
according to the site-host’s priorities.

“Buildings have a finite amount of power that can be allocated for EV charging,” Kyle
Lyons of EverCharge explained. Once this is used up, costly upgrades are required to
meet increased demand. EverCharge provides a power management solution that
maximizes available power and achieves lower installation and operation costs by
minimizing the occurrence of demand charges. Typically, a building with 100 amps in
common-area power would be able to support 3 to 4 chargers, while EverCharge can
add up to 10 chargers. EverCharge offers apartments and condominiums a fully
managed service including driver billing and property reimbursement, ongoing
maintenance, customer support, and insurance.

“We work to put the right chargers in the right places,” Heidi Krantz said of NRG eVgo’s
mission. Price certainty and affordability are key objectives. The company provides a
turn-key approach for apartments and condominiums, workplace, and at-home charging, each with its own pricing plan consisting of a fixed monthly fee, as well as variable charging fees for multiunit and workplace users.

Rachel Moses noted that the type of hardware the site host chooses to install would
determine the costs associated with charging. Also, “it’s really important to understand
best and correct practices for conducting site surveys and assessments, which will
really help with understanding how installation costs can be optimized.”

Greenlots’ open standard networking lends itself to having different types of charging
hardware. The capability to vary the type of charging is also important. A fast charging
station in Atlanta provides juice to the public at one fee and to the owner’s fleet drivers
and employees at a different fee. The site host can also set different rates based on the
time of day.

“We are big proponents of non-networked charging,” said Charlie Botsford of
AeroVironment. Not that the company is anti-network. Its EV charging includes the West Coast Electric Highway, as well as networks in California, Texas, Indiana and Hawaii. Nonetheless, Charlie touted non-networked charging as a cost-effective solution for many workplaces, apartments and condominiums, and fleets. Benefits include no network fees, lower equipment costs, and higher reliability. Still, he acknowledged, “one size does not fit all.” Hosts need to determine their goals and put together a longer-term plan that allows for growth.

Electric Vehicle Display at NC Transportation Museum

The Triad Electric Vehicle Association (TEVA) currently has an electric vehicle display at the North Carolina Transportation Museum in Spencer, NC. On June 19, 2015, TEVA began the display at the museum. The opening display was a home built Ford Festiva electric conversion and a Zero motorcycle. The second display consisted of a Nissan 240 sx converted to electric at Alamance Community College,  an electrathon racer and a BugE. 

Great job TEVA! Thank you for helping to increase awareness of electric vehicles!



EV Prototype RacerTEVA1

ELECTRATHON is a type of ELECTRIC MARATHON in which the winner is determined by how far you go in a certain time with a given amount of battery power. ELECTRATHON AMERICA class competition uses specific design rules to ensure safe and fair competition. Events are held around the country.  This electric vehicle rally is an exciting new environmentally progressive sport.

The Objectives are:

• To drive electrically powered vehicles as far as possible for one hour on a closed loop course using limited electrical energy.

• To provide a forum where skill and ingenuity may be displayed, compared and tested.

 • To improve public awareness and understanding of efficient alternative electric vehicles.


These vehicles are single person, lightweight, aerodynamic, high efficiency, electric vehicles with three or four wheels. They must meet specific design and safety rules. They are powered by deep cycle lead acid battery packs not exceeding 67 pounds. Only sealed lead acid batteries will be allowed.

This Carbon/Kevlar composite monocoque vehicle was originally raced in Maine and holds a record of 62 miles in one hour.  (Monocoque (/ˈmɒnɵkɒk/ or /ˈmɒnɵkoʊk/) is a structural approach whereby loads are supported through an object’s external skin, similar to an egg shell. The technique may also be called structural skin.)  It was brought to NC and modified to compete in the Shell Eco-marathon for James Dudley High School using Lithium batteries.

Shell Eco-marathon challenges student teams from around the world to design, build and test ultra energy-efficient vehicles. With annual events first in the Americas, then Europe and Asia, the winners are the teams that go the furthest using the least amount of energy.  Winners in the electric prototype vehicle have recorded >410 miles on one kilowatt hour of electricity or the equivalent of  13,000 mpg (37 kWh/gallon). The events spark debate about the future of mobility and inspire young engineers to push the boundaries of fuel efficiency.

This vehicle now serves as a prototype for the STEM Cycle Challenge as part of the EV Challenge.  The challenges change year to year (efficiency, hill climbs, obstacle courses,etc).  Many events occur at the North Carolina Center for Automotive Research (NCCAR, Garysburg).    www.evchallengekids.org



The design goal was to create a simple, low cost personal mobility vehicle that could function in a four-season environment on city streets.  This design evolved from Electrathon racing.

 The vast majority of vehicle trips are local (20 miles or less) by one person

(75%) within the community. This is where people live. This is also where livability is threatened by pollution and congestion. Their personal mobility options should be compatible with those community values.

Local urban transportation is perfectly suitable for electric power since electric motors produce good torque and low end power for stop and go traffic, do not need transmissions, are off at signals because they do not need to idle.

 A small battery pack is adequate for these short trips and re-charging opportunities are available everywhere within the gird, from every outlet. Every convenience store is a power station. Energy efficiency is 1 cent per mile.

 A light-weight vehicle is suitable for many short trips within the community provided if offers some minimum features typically not found on two wheeled bicycles and scooters:

Cargo capacity         (two bags of groceries)

Stability                      (three wheels)

Visibility in traffic      (Fairing shell)

Weather protection  (wind and rain)

 To achieve these design goals, a three wheeled Cyclecar stance (two wheels in front, one in rear) provides the most stable configuration. As such, the vehicle is licensed and insured as a motorcycle and would meet D.O.T. standards for this vehicle class. All controls are handlebar mounted and hand operated.

 A single piece fairing provides wind and weather protection, yet tilts forward to allow easy access and exit. The open sides eliminate the need for opening windows or doors yet permit hand and arm access to mail boxes, drive up windows etc.

 The fairing also reduces aerodynamic drag significantly, while increasing visual mass and presence in traffic. The driver sits at automotive height with other drivers, yet the smaller vehicle footprint creates more maneuvering room within the traffic lane.

 As a neighborhood use vehicle, performance need not exceed 40-50 mph enabling the vehicle to be quick but not fast since high-speed freeway traffic situations and the associated risks are avoided.

 Slower surface traffic conditions prioritizes maneuverability for parking, enabling four vehicles to park in one automotive parking space, as well as the many small spaces not available to cars.

 This concept is unique in vehicle architecture and is an appropriate design option for personal mobility in an age of sustainability and energy efficiency.
