Coding regulation for swapping power battery pack of electric vehicles
1 Scope
This standard specifies the basic requirements, code structure and data carrier of unified coding of swapping power battery pack of electric vehicles (hereinafter referred to as "battery pack").
This standard is applicable to the use, maintenance, management and traceability of battery packs in battery swap mode.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this standard, the terms and definitions given in GB/T 29317 and the following apply.
3.1
power battery pack
unit composed of several battery cells or power battery modules, case, battery information acquisition unit, related electrical and mechanical accessories, etc.
3.2
battery pack code
unique identification number composed of a group of numbers and English letters with certain meaning to represent the main attributes of the battery pack
4 Basic requirements
4.1 Uniqueness
A battery pack code shall be unique to the battery pack.
4.2 Conciseness
The battery pack code shall be as short as possible, so as to occupy less space in the memory of a machine and reduce the code error rate.
4.3 Applicability
The battery pack code shall reflect the product features such as battery pack connector, locking mechanism, battery type, capacity, etc.
4.4 Stability
The battery pack code shall remain constant if it is determined.
4.5 Extensibility
The battery pack code shall have backup capacity, to adapt to the needs of code extension.
5 Coding
5.1 Code structure composition
The code structure shall consist of two parts, as shown in Tables 1 and 2. The first part is design information and the second part is feature information. The two parts can be coded separately or together.
Table 1 Code structure in the first part
Basic structure Meaning
X1 X2 X3 Manufacturer code
X4 Product type code
X5 Battery type code
X6 X7 Specification code
X8 X9 X10 X11 X12 X13 X14 Traceability information code
Table 2 Code structure in the second part
Basic structure Meaning
X15 X16 X17 Manufacturing date code
X18 X19 X20 X21 X22 X23 Serial number
X24 X25 X26 Rated capacity of battery pack
X27 X28 X29 X30 Nominal voltage of battery pack
X31 X32 Connector code
X33 X34 Locking mechanism code
X35 X36 Case structure code
5.2 Code structure representation method
5.2.1 Manufacturer code
Manufacturers include production manufacturers, echelon use manufacturers and importers. The manufacturer code is represented by three digits of English capital letters, numbers 0 to 9, or a combination of letters and numbers, which are uniformly distributed by the industry administration department. Letters that are easy to be confused with numbers, such as O, I, Q, S and Z should not be used.
5.2.2 Product type code
The power battery pack, battery module and battery cell are represented by capital letters P, M and C respectively.
5.2.3 Battery type code
The battery type code is represented by the battery material type, i.e., an English capital letter, as shown in Table 3. For multi-component mixed material system, coding is conducted based on the component with the maximum content; in case of two or more components with the same content, the one with inferior safety shall be adopted for coding.
Table 3 Battery type code
Battery type Code
Ni-MH battery A
Lithium iron phosphate battery B
Lithium manganate battery C
Lithium cobaltate battery D
Ternary material battery E
Super capacitor F
Lithium titanate battery G
Others Z
5.2.4 Specification code
The specification code is represented by two digits of English capital letters, numbers 0 to 9 or a combination of letters and numbers. It is defined by the enterprise and refers to different product specifications and models. The enterprise needs to record the customized specification code. Letters that are easy to be confused with numbers, such as O, I, Q, S and Z should not be used.
5.2.5 Traceability information code
The traceability information code is represented by seven digits of English capital letters, numbers 0 to 9, or a combination of letters and numbers. It is defined by the enterprise. Traceability information code is necessary for new power battery products while unavailable for those in echelon use. The enterprise needs to record the customized traceability information code. Letters that are easy to be confused with numbers, such as O, I, Q, S and Z should not be used.
5.2.6 Manufacturing date code
The manufacturing date code shall be represented by three digits of English capital letters and numbers, in which, the first digit represents the year, to be used in accordance with Table 4 (in 30-year cycling); the second digit represents the month expressed in hexadecimal values; the third digit represents the calendar day used in accordance with Table 5.
