SITING AND DESIGN GUIDELINES FOR ELECTRIC VEHICLE SUPPLY EQUIPMENT (EVSE)
INTRODUCTION OVERVIEW Overview Charging Basics Levels of Charge
Charging stations are the point of connection to the electrical grid for electric vehicles (EVs), and the point of power for EV drivers. With the anticipated growth of EVs as a widespread transportation choice, the incorporation of electric vehicle supply equipment (EVSE) will become a critical element of city and town planning and designing from a master plan for site-specific installation. EVSE is a new infrastructure typology. Unlike traditional fueling stations for gas engine vehicles, EVSE lets drivers charge up at home, at work and countless places in between. In fact, this is one of the central value propositions behind EVs—the ability to charge from the grid anytime, anywhere. Estimates suggest that approximately 80%–90% of charging occurs at home, and nearly all of those homes are of the single-family variety. These design guidelines focus on the other 10%–20% of charging—multi-unit dwellings; publiclyaccessible locations such as downtown lots, on-street spaces, and highway stops; and private locations including offices and fleet depots—which are critical to establishing a full network of charging options. Expanding the infrastructure network will help make EVs a viable option for all drivers, even those without garages. The benefits come from extended infrastructure networks that are consistent, accessible and easy to use from place to place. EVSE deployment depends on cooperation, a process in which municipalities, the development community and the EV industry will all play leading roles. The purpose of these design guidelines is to identify and diagram key siting and design issues that are relevant to local governments as well as developers, homeowners, businesses, utility providers and other organizations interested in best practices for EVSE implementation.
The guidelines are organized into two main sections. ELEMENTS OF SITE DESIGN Site-level planning creates the user and public interface for EV charging. Critical factors in early EVSE deployment include the following: • Accessibility and ease of use • Visibility • Safety for installers, users and the public The guidelines explore communication networks, connection to the grid and user interface, as well as considerations that range from the parking spot up to the urban scale. Every site is unique. These guidelines set out a framework for analyzing site conditions, typical issues and for locating additional resources. INSTALLATION SCENARIOS These guidelines present analysis and site design solutions that approach these considerations from the perspective of installation scenarios. Surface lots, on-street parking, parking decks or garages, in-transit and trucking applications comprise the primary installation scenarios that, collectively, cover a majority of potential EVSE applications. Siting and installation of EVSE will depend on a number of considerations, including: proximity to power supply, parking space size and orientation, pedestrian traffic, lighting and visibility. Many of these considerations are not yet standardized in terms of functionality, and others fall outside the realm of the standards and codes system, such as aesthetics. Each EVSE installation will be different, so these guidelines takes the important step of establishing baseline considerations that are predicated on a typology of sites.

CHARGING BASICS EVSE COMPONENTS EVSE delivers electrical energy from the power source to the EV, and ensures that an appropriate and safe flow of electricity is supplied to the vehicle. EVSE is the main interface between user, vehicle and utility. BATTERIES Most EVs use lithium-ion batteries for their relatively good power performance, energy storage density, rapid charge capability and long life span. The size and energy density of batteries will greatly impact the future of EV range, functionality and consumer cost. As storage capacity increases—and as battery size and weight decrease—charging times and driving distance will change according to new technology. CHARGING STATION There are currently three categories of charging stations, which correspond to the three levels of charge detailed in the diagram on the following page. The charging station acts as the point of transfer from grid to vehicle, and for level 2 and up contains network communications, utility communications and monitoring, payment interface and, oftentimes, user information opportunities, such as advertising screens. The majority of the charging operation actually occurs inside the vehicle’s on-board charger, where the conversion from alternating current (AC) to direct current (DC) takes place at charging levels 1 and 2, and the battery charge is regulated.
CONNECTORS AND CORD SETS Most EVs and EVSE use the Society of Automotive Engineers (SAE) J1772 connector and receptacle that is standard for both level 1 and 2 charging equipment. Nearly all EVs come equipped with a portable level 1 cord that can plug into a typical wall outlet. Standardization in this area is an ongoing issue for DC fast charging. Almost all current DC fast charge EVSE in the US use the CHAdeMO connector, developed in Japan and used by Japanese EVs like the Nissan LEAF and Mitsubishi iMiEV, allows vehicles to connect to DC fast chargers. In October 2012 the SAE finalized the standard for a “hybrid” connector, which allows all charging to occur through a single receptacle on the EV. American auto manufacturers are expected to begin installing in vehicles beginning in 2013. The National Electrical Code (NEC) requires that cords be no longer than 25 feet, unless the charging station is equipped with a retraction or other cord control device. However, experienced installers recommend site design that will require no more than 3-5 feet of cord distance from vehicle to charging station or outlet to minimize tripping hazards.

SITE SELECTION AND DESIGN
SITE SELECTION
Site Selection Connection to Power Networks and Communications Existing Infrastructure EVSE Interfaces
Selecting a site for EVSE installation will likely require consideration of a combination of factors. While every site is unique and every EVSE host has priorities for installation, common physical elements characterize every EVSE site design.
a driver’s charge is complete. Complications for network connections arise in garages, where repeaters may need to be installed in order to guarantee network signals. Potential installation sites should be assessed for their network connection ability.
Site Design Elements Installation Access Operation
CONNECTION TO POWER When installing EVSE or EVSE-ready wiring, a dedicated circuit may be required or optimal. This can be added to an existing panel, or planned for in new construction. Dedicated circuits may require a new conduit, in addition to the conduit running from the panel to the EVSE’s location. Costs rise as cable length increases due to the installation costs of construction and trenching. Experienced installers recommend not exceeding 25 feet of conduit from panel to EVSE site, but this will vary widely.
EXISTING INFRASTRUCTURE Construction costs are the number one driver of added expense for EVSE, and the cost differential depends on the work required. Existing elements such as landscaping, walkways, curb cuts and other structural elements should be considered in an EVSE site plan. These elements add costs for removal or relocation, in addition to acting as barriers to accessible charging. Trenching, curb cuts and drilling through hardscaping or structural elements to add new conduits to connect EVSE to power sources can also be cost prohibitive. When possible, consider trenching through landscaping, although the EVSE should always be mounted on a concrete or other hard surface pad and protected from traffic.
Most facilities have accessible 120V circuits sufficient to power level 1 EVSE. Level 2 charging requires 208-240 volts and at least 15-30 amps. Many jurisdictions require or recommend a dedicated branch circuit for level 2 charging. The existing electrical panel in most installations, especially older structures constructed prior to 1960, will not have the system capacity to handle large and continuous loads. While level 2 EVSE is similar to other household appliances like clothes dryers, the continuous nature of the load may be a burden on the system. Installation of dedicated branch circuits/new panels may reduce safety risk and assist with peak load management in scenarios with multiple charging vehicles. NETWORKS AND COMMUNICATIONS Most public EVSE will contain an advanced metering system and link to a network that tracks usage, bills customers and manages electrical loads. Some EVSE will connect to telecommunications networks using wi-fi, Ethernet or cellular connections. This type of communication is especially important for managing user messaging and other technology advances that regulate information about available charging stations and when

1) NETWORK INTERFACE Many EVSE and EV manufacturers include onboard or on-unit technology enabling network communications and metering. Networks help maximize drivers’ access to EVSE by providing a mechanism through which drivers can most efficiently locate and cycle through EVSE parking spaces. Car to parking spot communication occurs through cellular network communication, alerting drivers to charging space locations in public areas through on-vehicle systems or smart phone apps. Developments on the horizon include built-in sensors that help determine if spaces are free. Consumer to charging network communication enables payment for publicly-accessible EVSE. Public EVSE will need to track usage and potentially bill consumers by charging network, typically connecting to back-office billing software. Such communications will involve an ongoing evolution of business models; currently, most networks require members to swipe an access card that links charging to an account. Not all networks are yet compatible across charging platforms, but innovation in the area of communications will ultimately improve overall efficiency and ease of use. EVSE to utility communication can enable better service, even adapting the rate of flow of electrical current to the unit, such as at times when grid loads are high—and when rates peak.
In each of these communications areas, data collection will improve systems and let us learn more about EV charging demand. PHYSICAL NETWORKS EVSE is connected via physical road and highway networks, and electrified corridors extend the effective battery range of an EV. ENFORCEMENT MECHANISMS Networks can help mitigate emerging issues in the EV driver community. Systems like alerts and other communication-based approaches can help ensure more efficient access to and use of publicly-accessible EVSE charging spaces. Network-based communication and community enforcement may help to avoid regulatory enforcement—a more costly approach for local jurisdictions responsible for ticketing and towing. As an alternative to enforcing parking ordinances, networks can disincentivize prolonged parking by charging for time in addition to electricity, where allowed.

ADDITIONAL ELEMENTS MOUNTING APPROACH PROXIMITY TO POWER SOURCE
The ability to connect to a power source is the top priority for EVSE site design—without power, there is no charge. The EVSE’s connection to both vehicle and power source occurs across boundaries of ownership and management and includes both the public and private sectors. There is a potentially complex set of relationships and costs, with different aspects of the power connection occurring in one or both of two areas: the public realm, including the public right-of-way, and the private space. These relationships have physical and business implications.
Installing the EVSE close to the required PROXIMITY TO POWER SOURCE power source reduces the need for cutting, trenching and drilling to add new conduits LIGHTING to reach the EVSE. Additionally, the cost of TYPE OFcan ESVE installation be reduced if the existing conduit has adequate capacity for EVSE. PROXIMITY TO ELEVATOR METERING Separate or sub-metering allows electricity METERING used by EVSE to be isolated from the rest of CONNECTORS PROXIMITY TO BUILDING a building’ or structure’s energy usage, though distinguishing ENTRANCE usage between multiple cords of an EVSE can only be accomplished by the TECHNOLOGY EVSE itself. For locations with multiple EVSE, it is best practice to separately meter each. LENGTH OF CHARGING TIME Smart meters, through a network connection to the utility, help users and utilities to balance electrical use across peak energy times. SIGNAGE
ELECTRICAL CAPACITY Connecting EVSE to a power source will require evaluation of existing electrical capacity.EVSE This has two parts: the electrical system at the location of the EVSE installation, and the capacity of neighborhood systems to support many EVs charging at once. Electrical cabinets, panels and circuitry will need to accommodate the anticipated additional load. Some municipalities, such as Vancouver, Canada, have used their building codes to require that new construction allow sufficient space within electrical rooms for panels and other equipment required to increase capacity in the future.EVSE
!
Utilities will be at the center of discussions of capacity. In addition to ensuring safety where EVSE is installed, utilities are concerned with overloading local transformers. Jurisdictions such as Maryland have passed legislation that allows for the disclosure of EV owner data to utilities, enabling them to plan for neighborhood power needs.
HOST-OPERATOR AGREEMENTS Different ownership and management structures will determine the degree of difficulty EVSE PROTECTION associated with accessing power supply, running conduit and maintaining EVSE. The relationship of owners and operators is critical, as different business models will place different requirements on navigating these relationships. The utility will work with the host or operator to bring the power connection to the site.
CONSTRUCTION COST The cost differential for EVSE installation is represented by the power interface. Considering a site’s power sources and capacity will help plan for lower-cost installations that require less physical construction.

THE CHARGING EXPERIENCE Most EVSE is equipped with touch screens and video capability, providing a forum for user information, ranging from communicating EV driver account details to local news content. Branding also plays a role in bringing information to drivers. The user experience at the EVSE site presents branding opportunities for the EVSE host’s, installer’s, or partners’ purposes.

SIGNAGE AND WAYFINDING Regulatory Wayfinding
Signage designates EV parking spaces and helps EV drivers locate charging stations. Regulatory signage designates a space and restrictions regarding its use, while wayfinding signage directs drivers to charging stations; both should be provided in a consistent and accessible style.
Regulatory signs indicate who may park in a designated location. Common examples of regulatory include handicapped parking designations, curb striping, no parking or permit-only signs. Regulations can be communicated through wording or design, The United States Department of such as through the color. A report on EVSE Transportation Federal Highway Administration signage written by ECOtality for the EV publishes a guide, Manual of Uniform Project recommends a combination of visual Traffic Control Devices (MUTCD) that sets and written cues. These would include both signage standards used by road managers an EV symbol and regulatory instructions. A nationwide on all public and private roads. symbol and wording, such as “Electric Vehicle Local regulations also come into play. Local Charging Only,” can be used in combination. jurisdictions, property owners and parking managers will have preferences for look and Vertical or pole-mounted signage is the most function of signs. For EVSE, the goal should standard (please reference the following page be clarity and consistency, particularly in the for examples).

can work with local parking management strategies to establish clear expectations for EV and non-EV drivers. Time limits will also include the participation of local authorities or parking managers to enforce the regulations established on the sign. Information on the charging station should also indicate voltage and amp levels and any fees or safety information. Electrical codes will ask hosts to indicate the date of installation, equipment type and model and owner contact information on the EVSE.
WAYFINDING Wayfinding describes a system of signs that do just that—help people find their way. In the case of EVSE, wayfinding systems will direct drivers to EVSE locations. These signs can be located on adjacent streets, access points to parking areas and highways. Pavement markings can also offer additional guidance and point drivers to the exact spaces. It may also be beneficial to drivers if signs indicate the level of charging available. The MUTCD provides guidelines for developing wayfinding signage systems. Community wayfinding signs have a lower placement priority than other guide signs. MUTCD also suggests that color coding can be an effective way to differentiate between different types of destinations.
Where wayfinding signs can be installed will be an area of potential contention for EVSE. At present, community wayfinding signs cannot be installed on freeway or expressway main lines or ramps. Nor can they be used to designate primary destinations. Recognizing the need to connect a decentralized infrastructure system, moving forward, it will be necessary for communities and for the Federal Highway Administration to consider what type of destination an EV charging station is, and whether EV charging station locations can be indicated to drivers en route along major highways. COLOR AND SYMBOLS Currently, a variety of symbols, colors and wording are used for EVSE and the associated regulations. As such, signs can be extremely confusing and may result in non-EV drivers unintentionally using these spaces. Color choice also poses a communication problem. Blue is often mistaken for accessibility, green is mistaken for short term parking and red is associated with prohibited action.
the term “charging” to eliminate confusion for drivers of hybrid electric vehicles, or EVs that do not need to charge. This language also encourages drivers to move their EV once charging is complete. It is important to indicate the active use of the charging station for EVSE designated parking stalls. INFORMATION AND ADVERTISING The many surfaces of the EVSE can be used to display information, such as how to use the machine or level of power. Display screens also may provide status information for the user and other communications, including advertising and branding for the EVSE host or partners.
LANGUAGE There is a need for clear language on all regulatory and wayfinding signs. “No Parking Except for Electric Vehicle Charging” has been recommended to be used on regulatory signs. Signs should use

INSTALLATION CONTEXTS Implementation Considerations Factors Affecting EVSE Installation
This section is intended to illustrate basic site design concerns and wider implementation considerations, such as the motivations of the EVSE installer, costs and operational issues that are relevant to shaping EVSE deployment on a site-by-site basis. The installation contexts described in the following pages of this guide will place design issues in perspective. It is acknowledged that each context shown here would include a wide degree of site-specific variation.
IMPLEMENTATION CONSIDERATIONS
structural, utility or electrical work. Soft costs are incurred through the permitting, maintenance and network servicing of EVSE. In some cases, EVSE manufacturers and service providers will supply the EVSE unit for free if they are in position to collect data or fees associated with the EVSE usage. As a result, the business models of the EVSE manufacturing groups may have an influence on emerging EV locations based on their ability to collect fees in certain kinds of locations.
REGULATIONS Ordinances serve planning and permitting purposes at the city-wide scale and are MARKETS AND MOTIVATION another layer of agreement for developers and Placement of the EVSE will depend on host EVSE hosts. Liability issues associated with motivation. For example, green branding opportunities require prominent placement while hazards and accessibility are another regulatory concern. the provision of EV charging for employees might mean settling for more economically efficient locations.

1) COMMERCIAL Retailers and other commercial operators will be among the early adopters of EVSE. For retail and commercial parking, priority considerations may include satisfying customers, branding the retail outlet or serving employees. The outcomes for the decisions about site location and design will vary depending on the key host motivations. The chart on page 19 associates the EVSE decision-making process for commercial parking lots with iconography describing the relevant site design elements.

2) Pedestrian safety in commercial areas is critical. ADA requires a minimum of 36” clearance between building wall and street furniture or signage, so care should be taken not to obstruct pathways for safety and egress.

3) Commercial operators seeking to highlight “green” branding will choose to install EVSE in prime parking spaces. Priority locations communicate to customers the value that the EVSE host places on sustainable business, while incentivizing EV drivers to patronize their store. In some locations, however, such as hospitality businesses with long or overnight stays or those with valet parking, it may be more advantageous to position EVSE further out in the lot, leaving prime spaces free for all customers. 4) Installing EVSE in prime parking spaces will likely add additional expenses, as these spaces are often far from the electrical panel, which are commonly located at the back of a building. Trenching, running additional conduit and replacing paving are the types of construction activities that account for the primary expenditures associated with EVSE. 5) Placing EVSE close to the door is an incentive and an out-front location may act as an additional deterrent to vandalism or other damage. Care should be taken to allow sufficient room for user access, including curb cuts, as well as methods to prevent tripping over cords.
