ATTACHMENT A: Definitions

Authorized User. An individual authorized in accordance with this NPD to use NASA-controlled parking areas. This includes NASA employees, contractors, subcontractors, and visitors.

Conductive Charging. A protocol for connecting the electric power supply network to the Electric Vehicle/Plug-in Electric Vehicle (EV/PEV) for transferring energy to charge the vehicle battery and operate other vehicle electrical systems, establishing a reliable equipment grounding path, and exchanging control information between the EV/PEV and the supply equipment. The protocol includes a safety lockout, preventing current from flowing when the charger is not connected to the vehicle. It ensures that if a cable is not correctly inserted, power will not flow through it.

Electric Vehicle Supply Equipment (EVSE). Consists of the conductors, including the ungrounded, grounded, and equipment grounding conductors, the electric vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatuses installed specifically for the purpose of delivering energy from the premises wiring to the electric vehicle. Charging cords with National Electrical Manufacturers Association (NEMA) 5-15P and NEMA 5-20P attachment plugs are considered EVSEs.

Level 1 Charging. An alternating current (AC) charging method that allows an EV/PEV to be connected to the most common grounded electrical receptacles (NEMA 5-15R and NEMA 5-20R). The vehicle will be fitted with an onboard charger capable of accepting energy from the existing single phase AC supply network; the end user provides the cord. The maximum power supplied for AC Level 1 charging will conform to the values in Table 9 of Society of Engineers (SAE) J1772. A cord and plug EVSE with a NEMA 5-15P plug may be used with a NEMA 5-20R receptacle. A cord and plug EVSE with a NEMA 5-20P plug is not compatible with a NEMA 5-15R receptacle.

Level 2 Charging. An AC charging method that uses dedicated AC EV/ Plug-in Hybrid Electric Vehicle (PHEV) supply equipment in either private or public locations. The vehicle will be fitted with an on-board charger capable of accepting energy from single phase alternating current AC electric vehicle supply equipment; the cord is part of the charging system. The maximum power supplied for AC Level 2 charging will conform to the values in Table 9 of SAE J1772.

Level 3 Charging. A direct current charging method of EVSE that carries direct current up to a maximum of 350 kW.

Level 1 Charging Receptacle. A 110/120 volt electrical connection that provides electricity used for charging a PEV without a permanently connected cordset (cordset provided by vehicle), networked fee, or usage data collection device (which may require additional hardware costs and service fees over the cost of the electricity provided).

Level 1 Cordset. UL listed PEV accessory equipment that has on one end, a standard NEMA 5-15P, three-prong household plug that can be inserted into a Level 1 charging receptacle and on the other end, an SAE J1772 connector that plugs into a PEV.

Parking Area. Any federally owned or leased building, structure, or surface lot for vehicles, including motorcycles and bicycles.

Plug-in Electric Vehicle (PEV). A vehicle that (a) draws motive power from a battery and (b) can be recharged from an external source of electricity for motive power.

Plug-in Hybrid Electric Vehicle (PHEV). A plug-in hybrid electric vehicle is a hybrid electric vehicle whose battery pack can be recharged by plugging a charging cable into and external electric power source, in addition to itss on-board iinternal combustion engine powered generator.

Privately Owned PEVs. PEVs not owned or leased by a Federal agency, including PEVs that are owned or leased by authorized users.

SAE J1772 (International Electrotechnical Commission Type 1). A North American standard for AC electrical connectors for electric vehicles maintained by the SAE International and has the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler."

Workplace Charging Station Plan Development and Implementation

C.1 Only Centers and facilities with Workplace Charging Station Plans approved by the NASA Chief Sustainability Officer may install, operate, and maintain EVSE for privately owned PEVs in parking areas under the custody, control, or administrative jurisdiction of NASA.

C.2 Workplace Charging Station Plans will include the following attributes as they apply to the Center:

a. Accommodate the accessibility and operation of workplace vehicle charging for privately owned PEV within the Center resources and consistent with NASA authority and Federal appropriations law.

b. Promote sustainable commuting and work-related travel practices, including workplace vehicle charging for privately owned PEVs.

c. Consider appropriate design and deployment of fleet charging EVSE during all new major construction, repair, or alteration of Agency-owned buildings or parking facilities.

d. Consider the feasibility of incorporating EVSE in newly acquired leased space or where a concessionaire operates a parking facility at a Federal workplace.

e. Do not interfere with Federal fleet vehicle access to fleet EVSE.

f. Optimize authorized use of EVSE.

g. Implement a mechanism of labels or other markings that indicate that an employee or authorized user has a PEV and is reimbursing the Agency for the use of EVSE at specified parking locations.

h. Identify parking spots with access to an EVSE receptacle in a sufficient manner to denote service for PEVs to ensure that authorized users are aware of the charging opportunity. If a large percentage of parking spots in a parking area are capable of providing EVSE receptacles, Centers may decide that it is not necessary to reserve or have preference for PEVs in such parking spots.

i. Ensure a safe workplace charging experience. Some best management practices for safety and management of EVSE receptacles can be identified within the Department of Energy's Alternative Fuels Data Center.

j. Incorporate use of renewable energy where feasible and cost-effective.

k. Identify the funding source, acquisition plan, and full-cost reimbursement mechanism (if using appropriated funds) for purchasing and installing EVSEs.

l. Identify the plan and mechanism in advance for recovering, all operations and maintenance costs (including electricity costs) from authorized users. The fee related to the cost of electricity will ensure that the Center recovers its cost rates and users electricity consumption.

m. Assess fees for workplace charging at a given Center that are uniform for each type (Level 1, Level 2, or Level 3) of charging so authorized users who select a particular level of charging equipment pay the same fee, regardless of which charging unit is used. (Example: All Level 1 charging outlets at a specific Center require the same reimbursement fee).

n. In coordination with the Office of the Chief Financial Officer (OCFO), identifies the authority used, the assessment of fees and the collection of fees.

C.3 Plan reimbursement provisions may not include reimbursement for the following:

a. The hardware, construction, or installation of EVSE installed or constructed primarily for use by Federal agency fleet vehicles.

b. ESVE installed or constructed pursuant to appropriations for the purpose of installing or constructing charging equipment.

C.4 Center Sustainability Officer will report on plan implementation annually, which should include the following:

a. Status of implementation of charging initiatives and EVSE inventory.

b. The number and type of EVSE installed at sites with active workplace charging programs, the cost of the hardware and installation, and the fee assessed to the authorized users of the charging equipment.

C.5 EVSE inventory from the annual plan reports will be included in the annual motor vehicle fleet data call within the Federal Automotive Statistical Tool (FAST) Web site.
