A digital battery passport is an electronic document that tracks a battery’s life cycle. It stores important information like composition, production, usage, and recycling.

The EU is aiming for a more sustainable and circular battery economy. The passports are intended to promote environmentally friendly battery design and improve recycling processes. The life cycle of a battery should be extended as far as possible, and the recycling of components and raw materials should be as simple as possible – and well documented in the battery passport.

As of February 2027, all EV (electric vehicle), LMT (light means of transport) and industrial batteries exceeding 2kWh capacity on the EU market will need a passport.

The responsibility for adding the required information to the EU digital battery passport falls on the party placing the battery on the market. This typically refers to the manufacturer or importer who first introduces the battery into the EU market.

The passport contains details such as the composition and battery chemistry, the materials used, performance data and information on end-of-life recycling. However, the final requirements for the passport data have not yet been definitively defined.

The EU digital battery passport will be accessible through a QR code. This code will be affixed to the battery itself and will contain a unique identifier that links to the digital record.

The EU regulations specify that some of the data within the passport might be publicly accessible, while other information will be restricted to authorized users only. This ensures transparency for consumers while protecting sensitive details only relevant to specific stakeholders within the battery lifecycle.

The EU digital battery passport boasts a range of benefits across the battery value chain, impacting manufacturers, consumers, and the environment.

• Enhanced Transparency: Battery passports provide a comprehensive record of a battery’s characteristics, including its materials, performance data, and carbon footprint.
• Sustainable Production: By tracking a battery’s lifecycle through the passport, manufacturers are incentivized to adopt eco-friendly practices. This could involve using recycled materials, optimizing battery design for longevity, and incorporating responsible sourcing practices.
• Improved Battery Performance and Maintenance: The passport can include data on a battery’s expected lifespan and optimal usage conditions.
• Efficient Recycling and Repurposing: The passport can facilitate the recycling process by providing valuable data on a battery’s composition and disassembly instructions. This ensures efficient material recovery and promotes a more circular battery economy.
• Fairer Competition: With increased transparency in battery production and sourcing, manufacturers who prioritize sustainability can gain a competitive edge.

Overall, the EU digital battery passport is a significant step towards a more sustainable and transparent battery ecosystem in the European Union.

Yes, at least from a technical point of view. It is possible to supplement the mandatory data records with additional, voluntary data. So far, the regulations stipulate that a manual for removing the battery from the device and a manual for dismantling and removing the battery pack are mandatory. Contact details are also required to sources for spare parts.

As dynamic data is collected over the entire service life of the battery in addition to the static data, which is identical for each individual unit from a model or production series, a battery passport is required for each individual battery.

The protection of intellectual property is a key aspect that is naturally very important to all battery manufacturers. So far, the plan is to use restricted, role-based access guidelines to ensure that only authorized users can access the data intended for them. The exact procedures for authorization have not yet been finalized at the current time (04/2024).

This is indeed a very important aspect. The EU directives stipulate that third-party services must be explicitly integrated for back-up services so that data is not lost if a service provider leaves the battery passport chain for whatever reason.

In fact, in a circular economy there are numerous other players who reuse a battery, put it into operation for another purpose after 1st life use or recycle it. It must therefore be ensured that they can update or supplement the battery passport, either by updating the initially created passport or by creating a new one that is linked to the initial passport.

Yes, this is planned, but it has not yet been regulated very precisely in the guidelines. It is also not yet clear whether, for example, the required “information on accidents” will be required for all battery types and whether this is mandatory.

It is true that the regulations stipulate that the battery passport should be “based on a decentralized data system”. The use of blockchain is therefore not mandatory, but the use of blockchain or distributed ledger technologies (DLT) in general can make perfect sense in this context.

The QR code should be able to be read without a special reader and without an additional app; all that is needed is a smartphone or tablet with a camera. According to current knowledge, the QR code could, for example, function as a kind of digital rating plate and be standardized according to IEC 61406. This means that the link (after scanning the code) will take you directly to the corresponding battery passport.

The implementation of the battery passport along the battery value chain offers various economic, environmental and social benefits:

1. economic benefits:
   – Increased credibility and reliability of supply chain data
   – Simplified determination of residual value
   – More efficient recycling processes
2. environmental benefits:
   – Transition to a “second life” of batteries is facilitated when more data is available on the respective battery condition.
   – Easier recycling through precise documentation of the composition of each individual battery, etc.
   – By simplifying recycling, more raw materials can be reused. The content of recycled raw materials is to be significantly increased in the coming years.
3. social benefits:
   – Compliance with ESG standards in production is documented.
   – Improved consumer decision making through informed purchasing decisions and residual value determination

The introduction of the battery passport is associated with several challenges and disadvantages that must be taken into account for a successful introduction:

1. technical and system challenges:
– The battery passport system is technically complex
– Different roles and authorizations must be implemented uniformly in order to display exactly the data that is required depending on the role
-> There must be no isolated solutions; cooperation between different players is just as necessary as the creation of standards, but investment in new technologies is also essential.

2. challenges in terms of skills and resources:
– SMEs in particular are especially constrained by limited (human and financial) resources when implementing such large-scale projects.
– Need for early internal coordination and harmonized requirements.

3. involvement of interest groups:
– Ensure acceptance and active participation of stakeholders.
– Addressing privacy and security concerns.
– Effective communication of requirements and possible assistance in implementing or complying with the standards is of central importance.

By proactively addressing these challenges through collaboration, investment, capacity building and stakeholder engagement, the potential benefits of the Battery Pass can be maximized while mitigating potential drawbacks.

The challenges of the technical system and the battery passport are expected to impact stakeholders in different ways, depending on their role in the system:

1. impact on stakeholders:
– Responsible issuers of the passport (i.e. battery manufacturers or importers) may face challenges related to system design, data management and compliance with standards.
– Passport users (in various roles such as 2nd life users or recyclers) may have to adapt to new processes and integrate them into their workflows and systems.
– Regulatory bodies are responsible for enforcing standards, ensuring data security and monitoring compliance throughout the value chain.
2. measures for industry collaboration and investment:
– Stakeholders need to work together to overcome technical challenges, share data where appropriate and develop common standards.
– Industry players may need to invest in new technologies such as blockchain, IoT and data analytics to ensure or improve the functionality and security of the battery passport system.

The battery passport complies with EU legislation, in particular the EU Battery Regulation, by providing an electronic record for batteries as required by Article 77. This electronic record, or battery passport, contains specific information about the individual battery and its model. The specifications for the battery passport, including the timeline for implementation (from 18 February 2027), scope (for different battery types), responsibility (for economic operators) and access groups (including the general public and authorized bodies), are set out in the EU Battery Regulation.

• The main responsibilities for the accessibility of the battery passport and maintaining information accuracy within the battery passport include the following main tasks:
• assigning a unique identifier: assigning a unique identifier for each battery that is linked to the QR code affixed to the battery. This unique identifier facilitates access to the battery passport and ensures traceability of battery information.
• update and store information: Ensuring that the information contained in the battery passport is accurate, complete and up to date. This includes regular updates to reflect any changes in the status or characteristics of the battery during its life cycle. In addition, the data contained in the battery passport must be stored securely to ensure data integrity and accessibility.
• compliance with legal requirements: Compliance with the requirements set out in Articles 77 and 78 of the EU Battery Regulation, which describe the responsibilities of economic operators in the management of the battery passport. This includes compliance with certain technical and operational standards to ensure the effectiveness and reliability of the passport.
• By fulfilling these core responsibilities, actors involved in the battery value chain can ensure the accessibility, accuracy and reliability of the information stored in the battery passport. This in turn supports transparency, accountability and sustainability in the battery industry.

• The handling of batteries has a significant impact on the responsibilities associated with the battery passport as part of the battery passport. These impacts include:
• handling throughout the value chain: battery handling operations, such as manufacturing, processing, collection, transportation, recycling, reuse, repurposing and remanufacturing, can take place at different stages of the battery value chain. Each of these operations affects the information stored in the battery passport and may require updates or transfer of responsibility.
• transfer of responsibility: In certain cases prescribed by the EU Battery Regulation, the responsibility for the battery passport must be transferred from one economic operator to another. For example, when a battery is prepared for reuse, repurposing or remanufacturing and placed on the market again, the responsibility is transferred to the new economic operator. Similarly, if the status of the battery is changed to “waste” and the producer, producer responsibility organization or waste manager takes responsibility for the passport.
• complexity of data management: The dynamic nature of battery handling leads to complex data management within the battery passport. Ensuring that the information in the passport remains accurate, complete and up-to-date throughout the lifecycle of the battery requires coordination between multiple stakeholders and regulatory compliance.
• By understanding the impact of battery handling on the responsibilities associated with the battery passport, stakeholders can effectively manage data, ensure regulatory compliance and promote transparency and accountability in the battery value chain.

Some of the main challenges are:

• Selecting suitable data carriers and unique identifiers. It must be ensured that static elements such as QR codes always lead users to the latest battery pass information. It must also be possible to clearly assign the information to a specific battery (via unique identifiers, UIDs) without creating duplicate entries or battery passports. This is the only way to ensure data integrity and traceability.
• Routing in decentralized/distributed systems: Sometimes the data of a single battery pass originates from different systems of different access points. It is therefore necessary for flexible routing to bring together the correct data and to be able to display complete data records even if one of the actors involved should fail. It is essential that the various access points can refer to common standards, norms and data formats and actively implement them. This also applies to data from the supply chain, which must be seamlessly integrated.
