5、nication Between Plug-in Vehicles and the Utility Grid RATIONALE The use cases described here identify the equipment (system elements) and interactions to support grid-optimized AC or DC energy transfer for plug-in vehicles, as described in SAE J2847. Key system elements include the vehicles recharg
6、eable energy storage system (RESS), power conversion equipment (charger and/or inverter), utility meter, optional advisory sub-meter (EUMD), load management system (LMS), and equipment for control, monitoring, and communication. System elements may be optionally packaged in various ways (either sepa
7、rately or in combination) to deliver implementations tailored to a given environment, such as a residential, public or commercial charging location. Implementations may also vary in relation to the vehicle itself. The charger and charging control technology each may reside either on-board or off-boa
8、rd the vehicle; for example, off-board control may be implemented as a smart plug. Use cases are technology-neutral, leaving implementers free to choose technological solutions appropriate to specific scenarios. For example, depending upon the situation, communication may occur via local wireless (Z
9、igBee, Wi-Fi, etc.), power-line carrier (e.g., HomePlug PLC), vehicle telematics, long-range wireless (GSM, CDMA, WiMax, etc.), Internet protocols, or a combination of these methods.

Equipment diagram, depicting actors and physical components of the use case. Communication path diagram, depicting communication trans
25、ports and components. Activity diagram, depicting the interactions among use case actors. Sequence diagram, depicting the sequence of message flows in the use case.

DEFINITIONS 3.1 Alternative Energy Supplier (AES)Competitive (or alternative)
32、supplier of commodity service see ESCO. 3.2 Available Line Current (ALC) Available Line Current is transmitted by the EVSE using the Pilot duty cycle identified in SAE J1772. This indicates to the vehicle the maximum current draw for this premise. The purpose of this is for the vehicle not to reques
33、t more current that this and to not trip the premise circuit breaker.3.3 Advanced Metering Infrastructure (AMI) AMI or Advanced Metering Infrastructure typically refers to the full measurement and collection system that includes meters at the customer site, communication networks between the custome
34、r and a service provider, such as an electric, gas, or water utility, and data reception and management systems that make the information available to the service provider. 3.4 Charger The charger can either be on-board the vehicle or off-board. On-board chargers require AC energy transfer to the ve
35、hicle (either 120 or 240V single phase) and Off-board chargers are within the EVSE and require DC energy transfer to the vehicle. 3.5 Clearinghouse Organization that provides global PEV account services. Maintains information necessary to facilitate account validation and billing transaction when Cu
36、stomer is charging PEV at a location not served by the Utility that the Customer is enrolled with.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-SAE J2836/1 Issued APR2010 Page 6 of 2443.6 Control H
37、AN application characteristics that respond to control commands Direct - Turns load On or Off Cycling - Turns load On or Off at configurable time intervals Limiting - Turns load On or Off based on configurable thresholds 3.7 Consumer HAN Devices These are devices within the architecture that are pro
38、cured by the Consumer or a third party which is not the Utility. As an example, these devices include smart appliances, PCTs, and Energy Management Systems. 3.8 Control Device DLC programs enable utilities to remotely control and/or shut down participating customer equipment on a short notice. A con
39、trol device is installed. The utility exercises its Call Option by first notifying the participant (to the control device which then sends the signal to the vehicle) that an event has been declared for the next day. 3.9 Control Flow The representation of information, energy, or matter that is used t
40、o alter the behavior of a system. These are shown as dotted arrows on a data flow diagram (DFD) to indicate the source and destination of the flow. A flow may be both a data and a control flow, depending on how it is used by the system. This construct is used as a part of the functional decompositio
41、n process. 3.10 Control Specification (C-spec) The description of a combinational or sequential logic operation, the results of which can be used as the input to a process specification (P-spec), or to describe when a process is to be operational. Types include decision tables (DT), state transition
42、 diagrams (STD), and process activation tables (PAT). C-specs are shown as a single vertical bar on a data flow diagram (DFD) and are referenced by the DFD level they appear on, followed by an s-index (e.g., 2.3.3-s1, 4 s7). This construct is used as a part of the Functional Decomposition process. 3
43、.11 Customer Customer is the operator of a PEV and an electric customer of the home utility. Customer enrolls in an electric utility PEV program and has selected a PEV rate tariff. Customer is responsible for connecting PEV to an Energy Portal for charging. 3.12 Customer Account Customer Account is
44、assigned to Customer to collect charges for billing of energy usage. 3.13 Customer Energy Management System Customer Energy Management System can provide communication interface to PEV for communication of PEV status information (e.g., charging state, state-of-charge, charging rate, time to complete
45、 charge) on Customer viewable displays. 3.14 Data Flow The representation of information, energy, or physical matter that is transformed by a system. These are shown as solid arrows on a Data Flow Diagram (DFD) to indicate the source and destination of the flow. A flow may be both a data and a contr
46、ol flow, depending on how it is used by the system. This construct is used as a part of the Functional Decomposition process.

47、0 Page 7 of 2443.15 Data Flow Diagram (DFD) A diagram that shows the relationship between portions of a larger, more complex process as the process is decomposed. It captures the flow of data, energy, or physical matter between the portions. This construct is used as a part of the Functional Decompo
48、sition process. 3.16 Decision Table (DT) A type of C-spec that defines the conditions required to determine the value of a combinational logic function. A combinational logic function, as opposed to a sequential logic function, is one where its present value (output) is dependent only on the present value of its arguments (inputs). See State Transition Diagram. 3.17 Electric Service Interface (ESI) The interface between the vehicle and the Utility Grid. See EVSE. 3.18 Electric Utility Power System (Utility) The system that
