SCOPE This SAE Information Report SAE J2836/2 establishes use cases and general information for communication between plug-in electric vehicles and the DC Off-board charger. Where relevant, this document no

14、tes, but does not formally specify, interactions between the vehicle and vehicle operator. This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle battery of the electric vehicle through a SAE J1772 Hybrid coupler or SAE J1772 AC Level 2 type couple

15、r on DC power lines, using the AC power lines or the pilot line for PLC communication, or dedicated communication lines that is further described in SAE J2847/2.The specification supports DC energy transfer via Forward Power Flow (FPF) from grid-to-vehicle.The relationship of this document to the ot

16、hers that address PEV communications is further explained in section 5. This is the 1st version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was to record as much information on “what we think works” and publish. The ef

17、fort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version. SAE

23、blications are provided for information purposes only and are not a required part of this document: 3. DEFINITIONS 3.1 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

24、draw for this premises. The purpose of this is for the vehicle not to request more current that this and to not trip the premises circuit breaker.3.2 CHARGER The charger can either be on-board the vehicle or off-board. On-board chargers require AC energy transfer to the vehicle (either 120 or 240V s

25、ingle phase) and Off-board chargers are within the EVSE and require DC energy transfer to the vehicle.SAE J2836-2 Issued SEP2011 Page 4 of 19 3.3 ELECTRIC VEHICLE SUPPLY EQUIPMENT (EVSE) PEV connects to the grid using an Electric Vehicle Supply Equipment (EVSE). Electric Vehicle Supply Equipment (EV

26、SE) is the physical electrical cord and connectors that are specified by applicable SAE standards (e.g., SAE J1772, SAE J2836 SAE J2847 & SAE J2931.) that provide transfer of electrical energy from energy portal to PEV. This can be 120V or 240V AC depending upon connection. Two type of connection in

27、clude 1) EVSE cordset and 2) Premises Mounted version. The Premises EVSE would not include the charger for AC Level 2 energy transfer described in SAE J1772. This would expect the charger to be included on the vehicle. If the EVSE includes an off-charger, DC energy transfer is expected and the vehic

28、le would by-pass any on-board charger and use the one in the EVSE. This EVSE that includes the charger for DC Level 1 may also be capable of AC energy transfer at both 120V (AC Level 1) and 240V (AC Level 2) levels. The larger off-board charger in DC Level 2 systems is not expected to also deliver A

29、C since these are Fast charge stations and extended time at this location is not desired since 10 to 20 minute charges are desired. 3.4 ENERGY PORTAL Energy Portal is any charging point for a PEV. At a minimum, the Energy Portal is a 120V, 15A outlet but can also be a 240V Electric Vehicle Supply Eq

30、uipment (EVSE) outlet connected to the premises circuit. 3.5 ENERGY TRANSFER Energy Transfer is the process of flowing energy to the EV from the EVSE. 3.6 ENERGY TRANSFER STRATEGY A strategy that accounts for all of the electrical energy needs of an EV and the present status of all on-board equipmen

31、t, including the EV Storage Battery. It determines the rate that energy is to be transferred to the EV and how the ETS shall be operated to accomplish this. 3.7 FORWARD POWER FLOW (FPF) Forward Power Flow means the direction of energy for Charging a Vehicle is from the source to the vehicle 3.8 HOME

32、 AREA NETWORK (HAN) A HAN is an energy related network, contained within a premises used for communicating with devices within the premises. HANs do not necessarily require connectivity outside the premises, but may be connected to one or more external communication networks (e.g., Utility AMI, inte

33、rnet, cell phone network, etc.) using gateways, bridges and interfaces.Homeplug powerline adapters are an alternative solution for having your house completely networked using existing power lines. The advanced Homeplug powerline adapter is capable of transmitting data at up to 200 Mbps channel data

34、 rate. The Homeplug powerline adapter delivers maximum range and speed for voice, Internet, video, and music throughout your home or office. 3.9 INTEROPERABILITY The condition where components of a system, relative to each other, are able to work together to perform the intended operation of the tot

35、al system. Information interoperability is the capability of two or more networks, systems, devices, applications, or components to share and readily use information securely and effectively with little or no inconvenience for the user. As an example, a 10-mm box-end hand wrench and a 10-mm socket w

36、rench are interoperable, relative to a 10-mm hex-head bolt. The wrench and the bolt are both parts of a fastening system. The fact that the system will perform as required with either wrench establishes the interoperability of the wrenches and the bolt. SAE J2836-2 Issued SEP2011 Page 5 of 19 3.10 O

37、FF-BOARD/ON-BOARD BOUNDARY Off-Board/On-Board Boundary is the point where the ETS is divided into two physical parts. One part becomes realized within the off-board Electric Vehicle Supply Equipment (EVSE). The other part becomes realized within an Electric Vehicle. This boundary will be in differen

38、t places, depending on the system architecture. 3.11 POWER FLOW See Forward Power Flow (FPF), Reverse Power Flow (RPF), Grid to Vehicle (G2V), Vehicle to Home (V2H) and Vehicle to Grid (V2G) for further definitions. 3.12 RECHARGEABLE ENERGY STORAGE SYSTEM (RESS) Means a system that stores energy for

39、 delivery of electric energy and which is rechargeable 3.13 REVERSE POWER FLOW (RPF) Reverse Power Flow means the direction of energy for Discharging a Vehicle is from the vehicle to the load. 3.14 PLUG-IN VEHICLE Plug-in Electric Vehicle (PEV). Plugs into an Energy Portal (see actor definition belo

40、w) at a premises to charge vehicle. A PEV may be a BEV (Battery Electric Vehicle) that relies only on electric propulsion. A PEV may also be a PHEV (Plug-In-Hybrid Vehicle) that also includes an alternative source of propulsion power. 3.15 POWER FLOW See Forward Power Flow and Reverse Power Flow. 3.

41、16 POWER LINE COMMUNICATION Power line communication (PLC), also called power line carrier, mains communication, power line telecom (PLT) or power line networking (PLN) are terms describing several different systems for using electric power lines to carry information over the power line. Electrical

42、AC power is transmitted over high voltage transmission lines, distributed over medium voltage, and used inside buildings and homes at lower voltages. Power line communications can be applied at each stage. Most PLC technologies limit themselves to one set of wires (for example, premises wiring), but

43、 some can cross between two levels (for example, both the distribution network and premises wiring). In most cases, these technologies may be used on DC lines and in the absence of power. Since the power wiring was designed for the transmission of power and not for communications, many challenges ex

44、ist, such as faultless communications in the presence of noise and over long distances. Power line communications systems operate using a variety of modulation techniques (including frequency, phase or OFDM modulation schemes), and in different frequency bands. In general, the lower band solutions (

45、in the 10 490 KHz range) are used in applications with data rates less than 256 Kbps. The upper band (2 MHz and above), has been used for broadband applications. As there are many different incompatible proprietary, alliance specifications and standards, the issue of co-existence is a major concern.

46、 The medium can extend beyond the consumers premises and may be used for multiple different applications, from simple lighting control to video distribution in the home to communicating to the Utility electrical meter outside. One example of a PLC technology is HomePlug. Founded in 2000, the HomePlu

47、g Powerline Alliance, Inc. is the global leading open-standards based organization developing interoperable powerline communications technologies and certifying powerline-based products. With 65 members and more than 4.5 million HomePlug-certified products shipped worldwide, the organization has dev

48、eloped HomePlug 1.0 and HomePlug AV and continues to develop the HomePlug Command and Control and HomePlug BPL specifications for use in both to-the-home networking. SAE J2836-2 Issued SEP2011 Page 6 of 19 3.17 SEP 2.0 The Smart Energy Profile 2.0 Application Protocol is primarily a layer seven prot

49、ocol, built on top of an Internet Protocol stack. 3.18 SMART CHARGING Smart Charging describes a system in which PEVs communicate with the power grid in an effort to optimize vehicle charging or discharging rate with grid capacity and time of use cost rates. 3.19 UTILITY Utility provides electrical energy and typically refers to a collection of systems that include the Customer Information System (CIS), the Advanced Meter
