FOREWORD This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. The ability of Electric Vehicles (EVs) to correctly operate with the off-board electrical   supply equipment used to charge them is a major concern for the producers and consumers of such vehicles. This concern stems from the cost of developing an electric “fueling” infrastructure. If EVs are to gain wide wide acceptance, this infrastructure must, at the least, least,   provide consumers with the same level of conven ience that is available for today’s fossil-fueled fossil-fueled vehicles. Ideally, there would be a single set of physical and functional requirements for the interaction between an EV and the off-board equipment. Designing to those requirements would allow any EV to charge with any off-board equipment, regardless of the producer of the vehicle or off-board off-board equipment. This would be similar to today’s internal combustion engine vehicles and gasoline pumps for unleaded fuels. Today, there are two electrical energy coupling methods under consideration for EVs. One conductively   transfers electrical energy (AC or DC) through metallic contacts. The other inductively   transfers electrical energy through a separable transformer. These couplings are detailed in SAE J1772 and SAE J1773, respectively. Each of these physical coupling methods includes a means to communicate data that is necessary to control the transfer of energy to the vehicle. Unfortunately, these coupling methods are not physically compatible. Therefore, inoperability between EVs and equipment using different methods is not possible. `    ,   ,   , `  `    ,   , `    ,   ,   ,   , `  `  `    ,   , `    ,   ,   ,   , `    , `    ,   , `  `  `  `    ,   , `    ,   , `    , `    ,   , `  -

While inoperability between conductively and inductively coupled systems is not physically possible, each coupling method performs the same basic functions. When the combination of the EV and the off-board equipment is considered as a complete energy transfer system, there is no reason for the system’s functional requirements to differ due to the physical coupling method. The only variation as a result of coupling method is the locati on (on-board or off-board) where specific functions are accomplished. Defining standards for certain functions of the total system and standards for the communication of data that pass between the EV and the off-board equipment will insure interoperability of equipment with common coupling methods. Different coupling methods will require a different system architecture, not different functional requirements. Control of the charging of an EV’s storage battery is specific to the type of battery and th e configuration of the vehicle.  Also, energy may be brought on-board a vehicle for purposes other than charging of the battery. These other purposes are specific to the needs of a particular vehicle. From these facts it follows that the EV should be in control of the transfer of energy from the off-board equipment. This way, EVs can have significantly different needs without forcing functional differences into the off-board equipment. It also establishes the EV (and its producer) as responsible to properl properly y charge batteries, and allows charging requirements to evolve with developing battery technologies and EV experience. This document will define a set of functional requirements for an Energy Transfer System (ETS) for Electric Vehicles, independent of energy coupling method. It will also serve serve as an “umbrella” document by reference of other SAE documents written or modified to accommodate this application. It will define three different physical system architectures that correspond to: a.

Conductive AC coupling

b.

Inductive coupling

c.

Conductive DC coupling

Requirements will be included and detailed only to the level that will insure functional interoperability for systems with common physical architectures. When designing systems, there will be additional requirements to consider that that do not affect interoperability and are not included here. If requirements are found that affect functional interoperablity, they should be considered for subsequent inclusion under the SAE J2293 umbrella. This document has been jointly developed by the Electric Power Research Institute-National Electric Vehicle Infrastructure Working Council (EPRI-IWC), Charging Controls and Communication Committee and the SAE Electric Vehicle Charging Controls Task Force. The efforts of all who participated are greatly appreciated. TABLE OF CONTENTS 1.   1.1  1.2  1.3

SCOPE

SAE J2293 establishes requirements for Electric Vehicles (EV) and the off-board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, of architecture, is Battery responsible conversion of AC can beregardless used to charge the Storage of an for EV,the as shown in Figure 1. electrical energy into DC electrical energy that

FIGURE 1 - ELECTRIC VEHICLE ENERGY TRANSFER SYSTEM PHYSICAL CONTEXT The different physical ETS system architectures are identified by the form of the energy that is transferred between the EV and the EVSE, as shown in Figure 2. It is possible for an EV and EVSE to support support more than one architecture. This document does not contain all requirements related to EV energy transfer, as there are many aspects of an EV and EVSE that do not not affect their interoperability. Specifically, this document does does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utility as the source of energy to be transferred to the EV. `    ,   ,   , `  `    ,   , `    ,   ,   ,   , `  `  `    ,   , `    ,   ,   ,   , `    , `    ,   , `  `  `  `    ,   , `    ,   , `    , `    ,   , `  -

The functional requirements for the ETS are described using a functional decomposition method. This is where requirements are successively broken down into simpler requirements and the relationships between requirements are captured in a graphic form. The requirements are written as the transformation of inputs into outputs, resulting in a model of the total system. Each lowest level requirement is then allocated to one of four functional groups (FG) shown in Figure 2. These groups illustrate the variations of the three different system architectures, as the functions they represent will be accomplished either on an EV or within the EVSE, depending on on the architecture. Physical requirements for the channels used to transfer the power communicate information between EV and the EVSE are then defined as a function of architecture. Systemand architecture variations are referred to asthe follows: a.

Type A—Conductive AC System Architecture— Architecture —Section 7.2.1

b.

Type B—Inductive System Architecture— Architecture—Section 7.2.2

FIGURE 2 - EV ETS FUNCTIONAL GROUP SERIES ENERGY CONVERSION The requirements model in Section 6 is not intended to dictate a specific design or physical implementation, but rather to provide a functional description of of the system’s expected operational results. These results can be compared against the operation of any specific specific design. Validation against this document is only appropriate at the physical boundary between the EVSE and EV. See Section 8. 1.1

Document Overview

SYSTEM DEFINITION AND CONTEXT

The EV Energy Transfer System (ETS), shown in Figures 1 and 2, converts AC electrical energy from the Utility into DC electrical energy for storage into an EV Storage Battery. The system includes functionality that will be implemented both on-board and off-board as a part of the Electric Vehicle as Supply Equipment (EVSE). This system will not as be partitionedthe intoEV, specific physical components. It will be described groups of functions that are to be implemented part of the EV EV or EVSE, depending on which of three different physical architectures is desired. The different system architectures: Conductive AC (Type A), Inductive (Type B), and Conductive DC (Type C), each perform the same system total function. The difference is that particular sub-functions will be performed either by the EV, or by the EVSE, depending on the architecture. The ETS is defined to include all aspects of the conversion of AC electrical energy into DC electrical energy that will affect the functional interoperability of an EV and EVSE. This includes all aspects of the physical physical connection between an EV and EVSE such as communication signals and power forms. 5.1

External Interfaces

The ETS interacts with other functional systems that are not considered to be within ETS. This is illustrated in Figure 5. These interactions define the environment where the ETS must operate, and are the result of natural and mandated requirements. Some of these external systems are optional. Therefore, any particular ETS may or may not not include an an external interface to interact with them.

FIGURE 5 - ELECTRIC VEHICLE ENERGY TRANSFER SYSTEM FUNCTIONAL CONTEXT DIAGRAM The physical form of the external interfaces of ETS are not defined in this document. Their form will differ based on specific EV or EVSE physical designs. 5.1.1

Electric Utility Power System (Utility)

The Electric Utility Power System is responsible to provide common common AC electrical energy. It is supplied via a branch circuit that is protected as required by national national and local building codes for use with Electric Vehicles. The exact form of the AC electrical energy (i.e., voltage, frequency, etc.) is not of specific interest to the operation operation of the ETS. However, the ETS requires knowledge of the current rating of its branch circuit.

Electric Utility/Local Load Management System (LMS)

The Electric Utility/Local Load Management System (LMS) is an optional system that is responsible to manage the maximum load of the ETS on the Utility or the branch circuit.  An LMS will be located off-board off -board the EV, because it is specific to the Utility Utilit y or bra nch circuit. Therefore, LMS information will be brought into and out of ETS by way of the EVSE. It will then be communicated to the EV if necessary. EVSE may be designed with no acc accommodation ommodation for a connection to a LMS. When a connection is supported, the manufacturer ofthis the EVSE shall define the physical characteristics of the connection to conform to the functional requirements defined in document. Some manufacturers of EVSE may choose to physically include LMS functions within their physical physical designs. For example, a “time of day” function that would that  would allow the EVSE to transfer power only during off-peak rate periods could be incorporated into a specific EVSE design. However, this function would still be considered as outside the ETS’s functional scope. When present, the LMS may establish preferred and mandated load limits that the ETS will not exceed. exceed. A preferred load limit may be ignored if the EV User takes action to do so. A mandated load limit may not be ignored. Also, the ETS will provide load status information back to the LMS. A single LMS may interact with multiple ETS installations. installations. 5.1.3

Indoor Charge Site Ventilation System (VS)

The Indoorfor Charge Site Ventilation (VS) anisoptional system that is system responsible to provide a se specific level EV of ventilation an enclosed (indoor) System site where anisEV being charged. This is optional becau because a specific model may be listed not to require it, per the National Electric Code (NEC®, NFPA-70-1996), Article 625.  A VS will be located off-board the EV, because it i t is specific to the charging char ging site location. Therefore, VS information infor mation will be brought into and out of ETS by way of the EVSE. It will then be communicated to the EV if necessary. EVSE may be designed with no accommodation accommodation for a connection connection to a VS. When a connection is supported, the manufacturer of the EVSE shall define the physical characteristics of the connection to conform to the functional requirements defined in this document. When present, the VS may be required to operate, and to confirm its operation, prior to and during energy transfer. Confirmation should be to detect that the electrical circuit which provides power directly to the ventilation device (fan) is energized. If VS operation is required and no VS is connected to the ETS, or confirmation of operation is not received, then energy transfer will not take place. See NEC®, Article 625 for further information. 5.1.4

EV Storage Battery

The EV Storage Battery is an electrochemical energy storage device that is responsible to provide DC electrical energy to operate an EV traction system and other vehicular systems. It shall be expected that the charging voltages of EV Storage Batteries will vary from 100 to 500 500 V with charging currents up to 400 A DC. The EV Storage Battery is replenished, or charged, when a voltage gr eater eater than the device’s open circuit voltage is applied to it.   5.1.5

EV Mobility Management System (MMS)

The EV Mobility Management System (MMS) is the system or systems that is responsible to control the motion of the vehicle. This includes the propulsion, braking, and parking lock functions. In order to prevent damage to the coupling between the EVSE and EV, it is important that the vehicle be immobilized when a partial or full connection exists. It shall be expected that the MMS will prevent the EV from moving relative to the EVSE when a connection between the two has been indicated by the ETS. This may be accomplished by whatever means the vehicle vehicle manufacturer determines is appropriate. When making the decision to immobilize the vehicle due to a connection, other factors should be considered. For example, if the vehicle is moving at 50 km/h and a connection becomes indicated, then it may be inappropriate to take an immobilizing action.

Other On-Board Vehicle Systems

Other On-Board Vehicle Systems includes other electrical loads on the vehicle that operate from the same DC electrical energy that is used to charge the EV Storage Battery. These loads may operate during energy transfer and are typically, but not limited to, HVAC and EV Storage Battery thermal management systems. It shall be expected that these these loads may require a total of up to 5.0 kW of electrical power, and that any single load up to 3.0 kW may be switched on or off at any time. The stated expectations are not intended to limit the electrical electrical power used by other vehicle systems. However, these values were used during analysis to help define power stage overlap and power stage range values (see 6.3.1.2) that will prevent the switching of loads from exceeding the limits of a power stage. 5.1.7

EV User

The EV User represents the human operator operator of the ETS. It serves as a source of certain information that may alter the operation of the system. It is also the destination for system status information that may be presented to the human operator. The EV User may be located either off-board an EV while making a connection to EVSE, or on- board in the driver’s seat. Therefore, EV User information will be brought into and out of the ETS by way of the EV and the EVSE. It can then be communicated to the other location if necessary. The physicalisform of this interface willan likely of to operator input selectors available and displays. availability EV User information not intended to require EV consist or EVSE make the information to theThe operator. The of information that is actually presented to the operator, and the method with which it is presented, will likely be different for different EV and EVSE physical designs. Therefore, this interface can be considered to be optional. 5.2

Functional Content

The EV ETS is to provide the following three major functions as shown in Figure 6. 1.

Switch and convert AC electrical energy into DC electrical energy, including accommodation for voltage voltage controlled transfer.

2.

Determine that the system system is ready to properly transfer electrical energy from the Utility to the EV Storage Battery, including accommodation for an external VS.

3.

Control the amount and rate of transfer of electrical energy to the EV Storage Battery, including accommodation for an external LMS.

Each of the three major functions will be decomposed into smaller portions. The data flows between between these portions of ETS will be described to the level necessary to insure interoperability of an EV and EVSE of similar architecture. The functions that could be included as a part of ETS are unlimited. The three previous functions are considered to be the minimum necessary to support the early development of an EV energy transfer infrastructure. As the EV marketplace continues to develop, additional functions will need to be added. Future additions have been considered as architecture decisions were made so that the additions can be made without making existing equipment obsolete.                     `   ,   ,         `   ,         `   ,   ,         `   ,   ,         `             `             `         `   ,   ,         `   ,         `   ,   ,   ,   ,         `   ,   ,         `         `         `   ,   ,   ,   ,         `   ,   ,         `         `   ,   ,   ,         `         -

The ETS is based on on the constraint that the EV must be in control of the energy transfer process. This is to say that the EV must control the voltage and current that is presented to the EV Storage Battery and to the Other On-board Vehicle Systems.

Therefore, it isof important for vehicle manufacturers to control how Storageis Battery treatedofinhow order insure customer satisfaction and control warranty costs. 5.4

Physical Content

 An ETS, regardless of architecture (Type A, B, or C), will be implemented in two parts: an EV and an off off-board -board EVSE. There is no requirement requirement for a specific physical physical design within an EV or EVSE. EV designs may distribute functions allocated to the EV to existing physical components within the EV. 5.5 5.5.1

Physical Constraints EVSE - EV Connection

The ETS is based on the physical coupling coupling methods described in SAE J1772 and SAE J1773. These documents have been developed in parallel with this one to insure that these methods are capable of supporting the functional requirements of ETS. 5.5.2

EVSE - EV Communication

SAE J1772 and SAE J1773 define an SAE J1850-compatible channel to provide a communication network between the EV and EVSE. This network is optional for a Type A system and shall be required for Type B and Type C systems. systems. The usage of this network for the ETS application shall be considered “normal vehicle operation messages” as defined by SAE J1850, even though communication to an off-board device is required. 5.5.3

Type A and Type C EVSE - EV Connection Detection

The coupling method described in SAE J1772, in conjunction with the electrical requirements of the Control Pilot circuit, provides for the detection of an EVSE - EV connection by both the EV and EVSE. This is accomplished by transfer of the data items EVSE_Ready and Vehicle_Ready on this circuit. In order for the EV to detect a connection, connection, the EVSE must first indicate that EVSE_Ready is “READY”. See SAE J1772.  J1772.  5.5.4

Type B EVSE - EV Connection Detection

The coupling method described in SAE J1773 provides a dedicated switch for the direct detection of an EVSE - EV connection by the EV. However, the EVSE can only detect a connection connection by monitoring the SAE J1850 channel for activity from the EV. For a Type B architecture, the EV shall conduct some valid communication to the EVSE within 2.0 s of the coupler becoming fully seated in the inlet. The connection detection problem is further complicated by a utility power outage and recovery situation while a Type B EVSE and EV are connected. connected. If the outage is for anything anything but a short period, then the EV will likely go into a low-power stand-by (sleep) mode. When power recovers, the EV will remain inactive until some activity is present on the SAE J1850 channel. For a Type B architecture, the EVSE shall conduct some valid communication to the EV within 2.0 s of recovery from a utility power outage while the coupler is in the inlet. It may not be cost effective for the EVSE to detect when the coupler is in the inlet while the vehicle is in stand-by, or to tell the difference between utility recovery and a typical “off” or “stand -by” to “on” transition. Therefore, the best solution may be to conduct some valid communication to wake the EV whenever the EVSE enters an “on” or o r operational state where energy transfer could occur. --`,,,``,,`,,,,```,,`,,,,`,`,,``-`-`,,`,,`,`,,`---

Network Communication Delay

SAE J1850 defines a Carrier Sense Multiple Access (CSMA) network with nondestructive nondestructive contention resolution. This implies that access to the network (sending data) must be controlled in order to in sure that all communication will be accomplished. The minimum interval between consecutive transmissions of any individual data/message for this application shall be 100 ms. All messaging shall be defined with this as a requireme requirement. nt. The maximum allowable latency for any communication required for normal operation shall be 2.5 times the expected time. 5.5.6

EV Readiness to Communicate

SAE J1850 defines that nodes on a network may support a low-power standby (sleep) mode of operation where the node is capable of detecting network signal transitions for the purpose of returning to normal operation (wake (wake-up). -up). This is of particular interest when the power to operate a node is supplied by a battery, such as on an electric or or motor vehicle. The EVSE and EV must always be able to communicate in order to support support certain functions. Therefore, while connected together, the EV and EVSE shall maintain normal operation, or return to normal operation upon detection of network activity. See SAE J1850. 6.

FUNCTIONAL SYSTEM REQUIREMENTS

The following are the functional requirements for the ETS. These describe what the system is supposed to do, within its defined environment. They do not define how these requirements are to be accomplished. These requirements are independent of any particular technology or system architecture.  A simplified form of functional decomposition will be used as a method to describe the requirements of the system. Requirements will be captured as related elements which have inputs and outputs that may represent information, energy, or matter. Each element transforms its inputs into outputs, thus capturing the requirements as a model of the system. Large, complex elements (parents) are broken down into a number of smaller, simpler elements (children). These elements are connected by flows that represent the information, energy or matter that passes between them. For detailed information on this method of system specification refer to Strategies for Real-Time System Specification, by Derek J. Hatley and Imtiaz A. Pirbhai (Dorset House Publishing) The processes that describe ETS are shown in Figure 6. Each process will be decomposed to a level where it can be easily described. Also, an elementary process must be able to be be totally totall y realizable within an EV or EVSE for any of the three system architectures. This allocation will be shown in Section 7, by way of an intermediate architecture that consists of four functional groups. These groups will then be combined in three differe different nt ways that will represent the Type A, B, and C architectures. 6.1

Switch and Convert Electrical Energy

The purpose of this process is to convert convert AC electrical energy into DC electrical energy. It is decomposed as shown in Figure 7. The process will describe each step of conversion as AC is transformed into DC. It also includes switching elements to insure that conductive connections for conductive architectures will make and break connection without electrical potential across the power contacts of the connection. See SAE J1772.  All portions of this process are active (producing output flows) whenever the total process is i s active. There is no explicit process activation control. However, for a process to provide an output flow, all inputs necessary to determine that flow must be available (data triggering). 6.1.1

Detect AC Present

The purpose of this process is to determine if the characteristics of AC_Electrical_Energy from the Electric Utility Power System are such that the ETS will operate properly. The exact characteristics that should be considered when determining if AC_Electrical_Energy is appropriate for proper operation will vary as a function of a specific EVSE design and ETS architecture. Therefore, it is only practical to define general characteristics of AC_Electrical_Energy that can apply to any design or architecture. --`,,,``,,`,,,,```,,`,,,,`,`,,``-`-`,,`,,`,`,,`---

Convert AC to DC Power

The purpose of this process is to provide open-loop conversion of AC electrical energy into DC electrical energy. The residual AC content of the DC electrical energy is constrained in order that a current measurement system that measures average current may be designed.

Determine EVSE Ready to Transfer

The purpose of this process is to determine if all off-vehicle equipment within the context of the ETS is in a state where it is ready to support support power transfer from the Utility to the EV. This off-vehicle off- vehicle equipment is generally referred to as electric vehicle supply equipment (EVSE). Only conditions that directly relate to the readiness of EVSE should be considered here. Issues related to site ventilation ventilation should not be considered here, as these are considered as a part of the control structure. The exact characteristics considered when determining that the EVSE is ready to support power transfer will vary based on manufacturers’ specific specific EVSE designs. Further, the EVSE’s functional content will vary depending on the ETS architecture (see Section 7). Therefore, it is only practical to define general requirements that could apply to any design design or architecture. This results in no explicit flows into this process. Items for consideration should should include, but not be limited to: a.

Utility Recovery Delay

The purpose of this process is to provide a random time delay to the start of the energy transfer process after a Utility recovers from a power outage. This delay is only required when the Utility recovers while an EV is connected to the EVSE. The delay will allow an opportunity for the Utility’s automatic fault fault recovery equipment to operate without the load of EVs on the Utility. Further, the random element has the effect of slowly increasing the total EV load for the recovering portion of the Utility. This delay may be considered inconvenient by the EV User. Therefore, this process allows the User to override the delay by briefly disconnecting the EVSE from the EV. Allowing an individual User to override override the delay does not not significantly reduce the effectiveness of the random delay because of the low probability that a large percentage of Users will override at the same time. --`,,,``,,`,,,,```,,`,,,,`,`,,``-`-`,,`,,`,`,,`---

Determine Energy Transfer Status

The purpose of this process is to determine the status of the present energy transfer strateg y. Storage batteries and vehicle systems will differ from individual vehicle manufacturers, as well as between vehicles from the same manufacturer. Different batteries and different high voltage power systems will require different energy transfer strategies. Therefore, it is not practical to require or define exact charge control strategies or exact transfer strategies in this document.  All electric vehicle charging systems (specific battery charging equipment applied to a specific vehicle/battery) are identified as one of two types with respect to National Electric Code (NEC®, NFPA-70-1996), Article 625 —Electric Vehicle Charging System Equipment. The types are: a.

Those that have been certified as “...suitable to be charged indoors...” and, therefore, do not require specific mechanical ventilation for an indoor charging site.

b.

All others, considered considered suitable for indoor charging if, and only if, appropriate mechanical ventilation ventilation is operating at at the indoor charging site.

 An individual vehicle, typically t ypically with a fixed battery design, des ign, m ay be capable of multiple charge control strategies using the same charging equipment. The use of different strategies may alter the charging system’s need for mechanical ventilation ventilation for indoor charging. There are no restrictions that prevent changing strategy to accommodate various various indoor charging sites that may not have mechanical ventilation. 6.3.3.1

Usage_Mode_Time shall be assigned a value that indicates an estimate of the period of time that energy transferred to the vehicle will be, or will continue to be used for, for the present Usage_Mode. Usage_Mode_Time shall indicate 0 (zero) when no estimate is available or possible. 6.3.3.3.3

Ventilation Required

Vent_Required shall be assigned the value “TRUE” if mechanical ventilation for indoor charging is required for the present energy transfer strategy and the present EV Storage Battery, per the National Electric Code (NEC®, NFPA-70-1996),  Article 625. Otherwise, Vent_Required shall be assigned the value “FALSE”.  “FALSE”.   The value of EVSE_Location may be considered when selecting the present energy transfer strategy. If Vent_Required has has the value “TRUE” and Vent_Fault has the value “TRUE”, then energy transfer will not be allowed. In this situation, a different energy transfer strategy that will cause Vent_Required to be assigned, the value “FALSE” should be considered. 6.3.3.3.4

The number C shall be appropriately scaled to represent the number and configuration of the modules that make up the total EV Storage Battery. 6.3.3.3.7

ETS Sleep

ETS_Sleep shall be assigned a value of “TRUE” to indicate that the ETS has concluded the present energy transfer session and that the vehicle may enter a low-power (sleep) mode of operation when the conditions are appropriate, if such a mode is supported. Otherwise, ETS_Sleep shall be assigned a value of “FALSE”.  “FALSE”.  This will be used as a part of the SAE J1850 communication network to stop the transmission of messages from the EVSE. This communication channel must be idle in order for the EV to enter low power mode. See SAE J2293, J2293, Part 2. 6.3.4

Control Power Conversion of Electrical Energy

The purpose of this process is to determine the power level of the conversion process so that the present energy transfer strategy is met, and to determine if the present power stage’s power range is insufficient. It is expected that this process process   will implement some type of closed-loop control of the electrical characteristics of the EV or the EV Storage Battery, such as voltage or current. The exact control method will not be specified, except to describe what outputs are expected. The exact characteristics that should be considered to control the power co nversion will vary based on manufacturers’ specific vehicle designs designs and EV Storage Battery Technology. Therefore, no vehicle- or battery-specific flows are shown into this process. 6.3.4.1

The following shall be performed continually while this process is active: 6.3.4.3.1

Power Level

Power_Level shall be assigned a value less than or equal to Max_Po wer_Level that indicates the present energy transfer strategy’s desired power level of Conv_AC_Electrical_Energy. See 6.1.3.2. Power_Level shall be assigned a value greater than Max_Power_Level if, and only if, the power level indicated by Max_Power_Level is immediately insufficient to prevent the vehicle and its on-board components from eventual damage or shortened service life. Exceeding Max_Power_Level may have financial consequences consequences for the User due to the cost of energy and agreements with their Utility. Stage_Power_Limited should be considered considered when determining if the value of Power_Level should be increased. If power is limited, further increases in Power_Level will have no affect. 6.3.4.3.2 -

Power_Out_Of_Range shall be assigned a value of “HI” (“LO”), if the present strategy desires a power level of Conv_AC_Electrical_Energy greater (less) than what is available from the active power stage as defined by Min_Stage_Power and Max_Stage_Power. Otherwise, Power_Out_Of_Range shall not be assigned a value. Stage_Power_Limited should not be considered considered when determining the value of Power_Out_Of_Range. If power is limited for the present power stage, it may be a temporary condition, and power stages with higher power capability may also be limited. 6.3.4.3.3

Pulse Mode Enable

Pulse_Mode_Enable shall be assigned the value “TRUE”, if the present strategy calls for a positive -pulsed mode of operation as described in 6.1.3.4 and the value of Pulse_Mode Pulse_Mode is “SUPPORTED”. Otherwise, Pulse_Mode_Enable shall be assigned the value “FALSE”.  “FALSE”.   If the value of Pulse_Mode is “NOT_SUPPORTED”, then the EVSE is not designed to support a positive -pulsed mode of operation. See 6.1.3.4. 6.3.4.3.4

Pulse Period

Pulse_Lo_Period and Pulse_Hi_Period shall be assigned values that indicate the period of the P0 and P1 power phases of the positive-pulsed mode of operation described in 6.1.3.4 if the value of Pulse_Mode_Enable is “TRUE”.

SYSTEM ARCHITECTURE

There are 3 different system architectures for the ETS that determine how the elements of the functional requirements (see Section 6) are to be grouped into equipment (EVSE and EV) and how that equipment is to be connected. The detailed physical descriptions will be limited to the boundaries between the EVSE and the EV. The specifics of the design within the equipment is left to the manufacturer of the equipment. It is required that the equipment, viewed viewed at the boundaries, functionally act as the combined functional requirements that are grouped within.

Page 66 of 84

System architecture variations shall be referred to as the following: a.

Type A—Conductive AC System Architecture

b.

Type B—Inductive System Architecture

c.

Type C—Conductive DC System Architecture

The physical interfaces to the external systems will not be described.  The specifics are left to the equipment manufacturers. These interfaces are required to provide the data and electrical energy as described in 5.1. When optional external systems are not present or not supported by the equipment, then flows that would be sourced from that system shall be considered to be their defined default value. 7.1

Requirements Allocation

The ETS can be viewed as four (4) groups of functions. These groups are loosely defined as a series of switches, switches, converters, and the logic to operate them, which act to transform AC electrical energy into DC electrical energy as shown in Figure 2. In order to accomplish this transformation, the groups will function together by sharing information. These functional groups (FG) are not likely to be implemented as separate components. However, this grouping is convenient because it can represent the variation due to different system architectures. Each group will be implemented as a part of a piece of equipment, EVSE or EV, depending on the type (A, B, or C) of system. The control and process specification elements of the requirements model in Section 6 are each allocated to one of the four groups. Elements are optional or required for specific architectures, as indicated by “O” and “R”, respectively. Some optional elements are grouped as follows, and shall be implemented as a group by EVSE or EVs that support the option: a.

O1—Positive-pulsed power mode O1—

b.

O2—Voltage control mode O2—

c.

O3—LMS Support O3—

d.

VALIDATION

Validation of a specific ETS implementation against the requirements in this document must consider the document’s scope, which is to specify certain function of the EVSE and EV. The requirements are not intended to specify an actual design or physical implementation. Requirements at the boundary between the EVSE and EV are physical in nature to insure that equipment can connect together. The functional requirements are designed to insure that equipment of the same system architecture will operate together. Therefore, it is only appropriate to validate the function of the system at the physical boundary between the EVSE and EV. The individual functions of the EVSE and EV vary as the functional and physical boundary between them is redefined for different system architectures (see Section 7). The expected result at this boundary can be determined for any set of conditions and for any architecture, based on the functional model of the total ETS requirements (see Section 6). This model is the basis for validation, along with the physical boundary descriptions. For each system architecture supported, EVSE and EVs shall be tested to show only that the interfaces between them, as described in Section 7, act as the model predicts. Testing shall include appropriate variation to exercise all aspects of the model that have been included in the actual equipment. When optional functions have not been implemented, and when optional external systems are not supported, then flows that would be sourced from these functions/systems shall be considered to be their defined default value. Testing shall be across the manufacturer’s identified range of environmental conditions. It is important to recognize that equipment may not include physical elements that appear to be required by the model. However, the equipment shall functionally act as if it has these elements. For example, in a Type B system, EVSE is not required to have an actual AC switching device as described in 6.1.2. The EVSE, however, shall not transfer power across the EVSE-EV EVSE-EV boundary unless the functional equivalent of that process is “closed”.   9.

DATA DICTIONARY

Table 57 describes each flow that is present in the requirements model. This information shall be considered minimum requirements for the implementation of the ETS. Not all flows will be realized in every ETS architecture. The following key applies to the table: Data (d) Src. FG# Snk. FG# —  `    ,   ,   , `  `    ,   , `    ,   ,   ,   , `  `  `    ,

Indicates that the flow is information (data), as opposed to energy or matter. Indicates the Functional Group number of the source of the flow. An “e” indicates that the flow comes flow comes from outside (external) the defined context of the system. Indicates the Functional Group number of the sink (destination) of a flow. An “e” indicates that the flow goes outside (external) the defined context of the system. Not applicable.
