CX-0034 Data Model Battery Pass v2.0.0

FOR WHOM IS THE STANDARD DESIGNED​

The stand will be used by interested data providers and application developers who want to communicate the Digital Product Passport. A Digital Product Passport is a digital document that contains comprehensive information about a product throughout its lifecycle. See additionally chapter 1.1

COMPARISON WITH THE PREVIOUS VERSION OF THE STANDARD​

The battery passport aspect model has undergone a comprehensive transformation, marked by fundamental content and structural changes. This update represents a significant leap forward to reflect the latest battery regulation: Regulation (EU) 2023/1542 of the European Parliament and of the Council of 12 July 2023 concerning batteries and waste batteries, amending Directive 2008/98/EC and Regulation (EU) 2019/1020 and repealing Directive 2006/66/EC. It can be found under: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32023R1542&qid=1702049049074

A significant change involves the introduction of the Digital Product Passport through an import as a shared model. In the regulation, Chapter IX is dedicated to the Digital Battery Passport, encompassing details about the requirements, technical design, and operations. The details to be included in the Battery Passport are listed in Annex XIII.

ABSTRACT​

Due to requirements of the new regulation for batteries and waste batteries, a data model for Battery Passport was created, which increases efficiency of circular economy ecosystems of all partners in the value network. The Passport itself is defined by the usage of Catena-X shared services, a standardized data model and an application which will enable stakeholders to access the relevant data. The battery passport is a tool for the exchange of information, enables tracking and tracing of batteries and provides information about the carbon intensity of their manufacturing processes as well as the origin of the materials used, about composition of batteries, including raw materials and hazardous chemicals, about repair, repurposing and dismantling operations and possibilities, and about the treatment, recycling and recovery processes to which the batteries could be subject to at the end of their lifetime. The battery passport provides information about batteries placed on the market and their sustainability requirements. It contains information relating to the battery model and information specific to the individual battery, including details resulting from the use of the battery.

1 INTRODUCTION​

This document describes one semantic model used in the Catena-X network.

1.1 AUDIENCE & SCOPE​

This section is non-normative

The purpose of this document is the description of the Asset Administration Shell model Digital Product Passport. It defines the product identity and all relevant attributes as required from the regulation. The presented data model is described and illustrated in the following with the entities and properties and their interrelationships.

This standard is relevant for following roles:

  • Data Provider / Consumer
  • Business Application Provider

1.2 CONTEXT AND ARCHITECTURE FIT​

This section is non-normative

The Battery Pass provides foundations for digital infrastructures for its documentation, the exchange of basic information and update-relevant technical data – in particular, data that comprehensively describes supply-chain accountability, such as greenhouse gas footprint, working conditions in raw material extraction, or the determination of battery conditions. To participate, parts of the standard of the Digital Product Passport CX-0103 must be fulfilled, as the Battery Passport incorporates various modeling components into its structure. Whenever the shared model of the Digital Product Passport is utilized, it signifies a match between the two regulations. This demonstrates the seamless integration of the Digital Product Passport's regulations within the regulatory framework of the battery.

The Battery Passport is defined by the usage of Catena-X shared services, a standardized data model and an application which will enable stakeholders to access the relevant data. This version of the Battery Passport Data Model 4.0.0 consists out of the following information:

  • Passport Metadata
  • Product Identification (identifiers and typology)
  • General Information (manufacturing information)
  • Physical Dimensions
  • Chemical Materials (active, critical and hazardous material)
  • Circularity (carbon footprint, spare parts and sustainability documents)
  • Battery Performance (rated and dynamic values)
  • Conformity Documents
  • Safety Documents
  • Optional Other Sources

1.3 CONFORMANCE AND PROOF OF CONFORMITY​

This section is non-normative

The key words MAY, MUST, MUST NOT, OPTIONAL, RECOMMENDED, REQUIRED, SHOULD and SHOULD NOT in this document document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

1.4 EXAMPLES​

The JSON example can be generated from the SAMM.ttl file or be found in the current version 4.0.0 in the "gen" folder github repository.

1.5 TERMINOLOGY​

This section is non-normative

EoL : End of life

OEM : Original Equipment Manufacturer

Business Partner Number (BPN) : BPN is the unique identifier of a partner within Catena-x.

Aspect Model : a formal, machine-readable semantic description (expressed with RDF/turtle) of data accessible from an Aspect.

: Note 1 to entry: An Aspect Model must adhere to the Semantic Aspect Meta Model (SAMM), i.e., it utilizes elements and relations defined in the Semantic Aspect Meta Model and is compliant to the validity rules defined by the Semantic Aspect Meta Model.

: Note 2 to entry: Aspect model are logical data models which can be used to detail a conceptual model in order to describe the semantics of runtime data related to a concept. Further, elements of an Aspect model can/should refer to terms of a standardized Business Glossary (if existing).

2 ASPECT MODEL “Battery Pass”​

This section is normative

The battery accounts for about 40% of the added value in electric cars. It is therefore very important for sustainability and working standards in the automotive industry. The "Battery Passport" project by partners from industry and research therefore wants to design content and technical standards for a battery pass and show them in a pilot project. In this way, consumers can see at a glance what kind of batteries are installed, how they were manufactured and how sustainable they are.

The purpose of this document is the description of the Asset Administration Shell submodel Battery Pass. It defines the battery identity and all relevant attributes. The presented data model is described and illustrated in the following with the entities and properties and their interrelationships.
