Communication Protocols between Off-board Conductive
Charger and Battery Management System for Electric Vehicle
1 Scope
This Standard specifies the definitions of physical layer, data link layer and application
layer of the control-area-network (CAN)-based communication between off-board
conductive charger (hereinafter referred to as "charger") and battery management
system (hereinafter referred to as "BMS") for electric vehicle.
This Standard is applicable to the communication protocols between off-board
charger and BMS (or other vehicle control units that have charging control function) of
electric vehicles that adopt conductive charging mode.
2 Normative References
The following referenced documents are indispensable for the application of this
document. For dated references, only the dated edition applies. For undated
references, the latest edition of the referenced document (including all amendments)

3 Terms and Definitions
The terms and definitions established in GB/T 19596 as well as the following terms
and definitions are applicable to this document.
3.1
Frame
A series of data bits that constitute a complete massage.
3.2
CAN data frame
The orderly bit field that constitutes the CAN protocol for data transport, starting from
the Start of Frame (SOF); and stopping at the End of Frame (EOF).
3.3
Messages
One or multiple "CAN data frame" that have the same parameter group number.
3.4
Identifier
The identification division of CAN arbitration field.
3.5
Standard frame
The CAN data frame that uses 11-bit identifier and that is defined in CAN-bus.
3.6
Extended frame
The CAN data frame that uses 29-bit identifier and that is defined in CAN-bus.
3.7
Priority
A 3-bit field in identifier. It sets the arbitration priority during transport process, with
Grade 0 as the highest priority and Grade 7 as the lowest priority.
3.8
Parameter group; PG
The assembly of parameters sent in a message. The parameter group includes
command, data, request, response and negative acknowledge, etc.
7.1 In this Standard, the application layer is defined in manner of parameters and
parameter group.
7.2 Parameter group is numbered by adopting PGN, and each node identifies the
content of data packet according to PGN.
7.3 "Request PGN" is used to initiatively obtain the parameter groups of other
nodes.
7.4 Data are sent by adopting with periodical sending and event-driven modes.
7.5 In case that multiple PGN data need to be sent in order to realize one function, it
requires receiving multiple PGN messages of this definition to judge the successful
sending of this function.
7.6 When defining new parameter group, the parameters of one function, the
parameters of the same or similar refresh frequency and the parameters belonging to
one subsystem shall be put into one parameter group as much as possible;
meanwhile, on one hand the new parameter group shall make best use of the data
width of 8 bytes and the relevant parameters shall be put into one group as much as
possible, and on the other hand the expansibility of the new parameter group shall be
fully considered, one byte or bit shall be reserved for future modification.
7.7 When modifying the defined parameter group as given in Chapter 9, the
definition of defined byte or bit shall not be modified; the newly-added parameters
shall be relevant to the original parameters in parameter group and the irrelevant
parameters shall not be added into the defined PGN for purpose of saving the number
of PGNs.
7.8 During charging process, the definition of various fault diagnosis for charger and
BMS shall comply with the requirements for CAN-bus diagnostic system as stated in
5.1 of SAE J1939-73.2006. The specification for definition of fault diagnosis
messages is detailed in Appendix B.
7.9 The message sending options during charging stage are divided into mandatory
and optional sending items, and the message of mandatory sending item shall be sent
in strict accordance with the message format and content; if there is no need to send
invalid message unit or optional sen...
