Digital Product Passports (DPP)

We are developing a solution for creating digital product passports (DPP).
These DPPs are a key element of the EU's planned Ecodesign Regulation for Sustainable Products (ESPR). They are intended to improve the traceability of products and their components and promote the circular economy. The digital product passports are easily accessible by scanning a QR code on the product. They contain information such as the shelf life and reparability, the recycled content or the availability of spare parts for a product. The aim is to facilitate the EU's transition to a circular economy.

Digital Battery Passports - the first obligatory DPPs introduced

The digital battery passport is a core element of the new EU Battery Regulation, serves as the first digital product passport in the EU and will be mandatory for many types of batteries from 2027. It contains information on the composition of the battery (such as the origin of the materials and their recycling options), but also documents the entire life cycle of a battery along its value chain.
The aim of the battery passport is to improve transparency and sustainability in the battery industry in order to reduce the environmental impact of batteries and promote the circular economy.

The Clock is Ticking: Work on the Swiss “Battery Passport” in Full Swing

  • BloqSens Ltd enters a  partnership with  innovation center CSEM.
  • Together they are  developing the Swiss  battery passport.
  • From February 2027, all  industrial batteries in circulation in the EU  must be identifiable and traceable via a digital passport.

Basel, 28 May 2024 – As the EU will introduce a “passport obligation” for industrial batteries in 2027, Swiss market players will also have to adapt. BloqSens Ltd. has therefore teamed up with the technology innovation center CSEM to launch an EUcompliant digital battery passport “Made in Switzerland”.

Anyone travelling abroad must show their biometric passport, depending on their destination. This important document not only provides detailed information about a person’s identity, but also shows where they have been in the past. “Our battery passport fulfills more or less the same function for batteries,” explains Peter Krummenacher, CEO of Basel-based BloqSens AG. The company, which specializes in the development of IoT (Internet of Things) solutions, is pushing ahead with the development of the battery passport. Time is of the essence: By 18 February 2027, all industrially used batteries circulating in or exported to the EU must be identifiable and traceable via a passport.

Major consequences for Switzerland
What does the EU hope to achieve with this step – and why is this legislation also important for Switzerland? Basically, the battery passport is intended to promote the circular economy for industrial batteries. For example, a car battery can be adapted for use in a residential building. The converted battery can then be used to store solar energy. This second life cycle for resource-intensive batteries is an important step towards a more sustainable future. Theoretically, third and fourth life cycles are possible as well. In addition to this reuse, the focus is also on the recycling of the raw materials used in the construction of the batteries, since they contain useful metals such as nickel and cobalt, as well as rare resources such as lithium.

The battery passport issue is important for Switzerland for a very specific reason, as Andreas Hutter, Head of the CSEM Battery Innovation Hub, explains: “We have a large second-life industry in this country, which is already giving many batteries a new function and thus promoting sustainability.” This sector depends on the ability to continue exporting batteries to the EU or to source batteries from the EU. From 2027, companies in this sector will therefore also have to prove the identity and previous use of their storage systems by means of a battery passport. “A Swiss battery passport solution is therefore an important economic factor and a future competitive advantage,” emphasises Hutter.

The benefits of cooperation
In order to launch the battery passport “Made in Switzerland” on time, BloqSens Ltd. has joined forces with the battery experts at the technology innovation center CSEM. This collaboration is based on a battery prototype that is currently being developed at the CSEM Battery Innovation Hub. The prototype will be able to better map the condition of its individual cells and thus optimize its service life. On this basis, BloqSens Ltd. is developing its battery passport application. This is a key advantage: Since the CSEM prototype already represents the “smart battery of the future”, BloqSens Ltd. can design its digital passport solution to meet future requirements. The company is therefore a significant step ahead at the start of the project.

For the Swiss battery passport, Peter Krummenacher and his team are relying on a decentralized storage solution that makes use of the advantages of blockchain technology. As a result, the stored data is tamper-proof, can be updated automatically, and can be used transparently by authorized parties at any time. In the future, each battery will be labeled with a QR code that provides pre-defined user groups with specific information about the storage.

For Krummenacher, the collaboration with CSEM is a major step forward: “The experts at the CSEM Battery Innovation Hub are contributing their first-class battery expertise to our joint project, and we can take care of all the IT and security aspects.” The result is a battery passport that fulfills European requirements, represents a new seal of quality as a Swiss product, and can also classify the smart batteries of the future.

Why is it important that IoT data is stored tamper-proof?

Storing IoT data in a tamper-proof manner is crucial for several reasons, like integrity, authenticity, resilience, trust and compliance, which are vital components for the successful and safe deployment of IoT technologies in various domains.

Data integrity is guaranteed when sensitive data remains intact and complete. Tamper-proof storage of IoT data ensures its integrity, preserving its accuracy and reliability for extensive analysis and informed decision-making.

In the case of your IoT data, authenticity means that it can be assigned to its origin, i.e. the sensor or the measuring point, at any time. The use of the blockchain results in tamper-proof mechanisms that prevent unauthorized changes being made to the data. This ensures the authenticity and trustworthiness of your measurement data.

Data manipulation by both malicious actors and accidental internal errors is prevented, thus strengthening the resilience and reliability of your systems.

Immutable data foster trust among stakeholders: Tamper-proof data storage instills confidence in customers, partners, and investors. You can focus on your core business and innovations.

Data immutability enables organizations to comply with regulatory requirements and maintain a clear audit trail for accountability purposes.

What are the benefits of Blockchain technology in your solution?

By leveraging decentralized and immutable data structures, blockchain enhances data security, transparency, and integrity, while also promoting trust among participants.

Unlike traditional centralized databases, blockchain operates on a decentralized network of nodes, removing the need for a single point of control. This design distributes data across multiple nodes, making it more resilient against hacking attempts or single points of failure.

Data stored on the blockchain is cryptographically secured, forming an unchangeable and transparent ledger. Once data is added to the blockchain, it becomes practically impossible to alter past records without the consensus of the network, ensuring data integrity.

Blockchain uses advanced encryption techniques to secure data, reducing the risk of unauthorized access, data breaches, and identity theft. Each transaction is verified and agreed upon by the network, preventing fraudulent activities.

The distributed nature of blockchain allows all participants to access and view the same data in real-time. This transparency enhances trust and allows for efficient auditing processes, promoting accountability and reducing the chances of corruption.

Blockchain’s decentralized nature ensures that there is no central point of failure, making it more resistant to DDoS attacks and other malicious attempts to compromise the system.

Blockchain’s consensus mechanisms instill exceptional trust and authenticity in data handling.

Participants can confidently rely on data integrity and verify its origin, fostering unparalleled trust in interactions.
