Part 2: Communication protocol between off-board charger and electric vehicle. CLC/TS 50457-2:2008 4 1 Scope This Technical Specification applies to the communication d

19、ata link between external charger and electric road vehicle for the charging procedure, using the most common communication link. This Part 2 applies to communication data link between the off-board charging system with direct current and electric road vehicles. The aspects covered are the physical

20、layer, the data link layer and the communication applicative layer. This Technical Specification does not cover communication between dedicated off-board charger and their electric vehicle. Annex A gives an example of normal operation. 2 Normative references The following referenced documents are in

21、dispensable for the application of this document. For dated references, only the edition cited applies.

23、system embedded in the electric vehicle able to command and control the charging parameters of the off-board charger 3.2 charging parameters parameters including set points needed by the off-board charger to generate a current adapted to the vehicle battery 3.3 charging values values measured during

24、 charging process CLC/TS 50457-2:2008 5 4 Off-board charging system 4.1 General overview Electric vehicles will be equipped with different technologies, voltage and charging current batteries. In order to avoid any error during charging and to guarantee that the off-board charger will be able to cha

25、rge all existing and future batteries, the charge shall be managed by the vehicle. Any vehicle to be connected to a general purpose off-board charging system must include a charging control unit able to manage the charging process. 4.2 Charging process The off-board charger shall be able to supply c

26、ontrolled DC voltage and/or current to the vehicle battery. The charging values current and voltage shall be measured at least by the off-board charger. If the vehicle charging control unit also makes this measurement, a full redundancy system could be established to achieve a high safety charging s

27、ystem. The charging parameters shall be established by the vehicle charging control unit and sent to off-board charger in order to be used as set points. The charging measured values will be sent by the off-board charger to the vehicle charging control unit. 4.3 Safety process The start of the charg

28、ing process shall be allowed by both the off-board charger and the vehicle charging control unit. The charging process can be stopped at any time by the off-board charger or the vehicle charging control unit and shall be stopped in case of communication loss. 5 Communication interchange 5.1 Protocol

29、s basis The standard data interchange is based on ISO 14230. 5.2 Adaptation for off-board charging application The scope of ISO 14230 concerns requirements for diagnostic systems implemented on a serial data link layer, which allows a tester to control diagnostic functions in and on vehicle electron

30、ic control unit. The same protocol is used for the communication between an electric vehicle and an off-board charger for the charging procedure. After the initialization phase by the OBC, the VCCU shall control the charging process of the OBC. Contrarily to communication according to ISO 14230 wher

31、e the server and the client are fixed during all the session, the roles are definitively reversed after the initialization phase. 5.3 Initialization header values Initialization header values are those defined in ISO 14230-2 except for those specified hereafter. CLC/TS 50457-2:2008 6 5.3.1 Initializ

32、ation mode The initialization mode is 5 bauds only. 5.3.2 Address The address sent to open the communication to the vehicle charging control unit shall be 66 h (functional address). NOTE 66 h is the value 66 in hexadecimal code. 5.3.3 Key bytes The key bytes are defined in accordance with ISO 14230-

33、2 with for KB1: AL0 = 1 AL1 = 0 HB0 = 1 HB1 = 0 TP0 = 1 TP1 = 0 That is to say the following two key bytes: KB2 KB1 Hexadecimal code Decimal code 10001111 11010101 8FD5 2005 KB2 is the most significative key byte. The key bytes will define the state of the protocol; any change in the protocols for f

34、uture use will change the key bytes. 5.4 Message structure 5.4.1 Message length The maximum length for charging application shall be 16 bytes (included header and check-sums). 5.4.2 Message header values The message header values shall be changed and defined as follows: number of header bytes: 1 as

35、defined in 8.1.2. CLC/TS 50457-2:2008 7 6 Service definition 6.1 Basis The services definition is based upon the draft of ISO 14229 with the following main differences: diagnostic is hereby replaced by data interchange; client (tester) is replaced by the vehicle charging control unit (VCCU); server

36、(ECU) is replaced by the off-board charger (OBC); as there is only one server, no server identifier parameter shall be provided. 6.2 List of services used Table 1 List of services used Services of ISO 14229 used for this application Generic services (client) Generic services (server) Diagnostic mana

45、his request is used to inform the VCCU of the major characteristics of the OBC ChargerIdentification. This request is used to identify the OBC (for instance: OBC manufacturer, OBC owner, OBC version.) 7.2.3 Vehicle identification VehicleIdentification This service intends to identify the vehicle. It

46、 can be used for instance to provide the charger with an access control facility, it can identify the version of the communication protocol. In case of an unauthorised vehicle, the OBC shall answer to the request with a StopSessionRequest message. Any further request request in this session shall ge

47、t the same answer. 7.2.4 Starting charging process SetSafetyLimits The OBC shall not be allowed to supply any power before receiving this request. StartCharging From receiving this request, the OBC current setpoint is reset to zero and the OBC shall be ready to supply power to the battery. 7.2.5 Cha

The charging process will then be resumed using a StartCharging request. CLC/TS 50457-2:2008 10 7.2.6 Ending charging process This can occur in two differ

49、ent ways: from VCCU (normal end of process), the VCCU shall send a StopSession request; from OBC (for safety reasons or elapsed credit time for instance), any request other than StopSession shall get the StopSessionRequest answer. 7.2.7 End of communication After echoing a StopSession request, the OBC will remain idle till a next initialization. 7.3 Other functions TestDevicePresent can be used at any time to avoid time-out.
