Beginning in February 2027, all new traction batteries, two-wheeled car batteries, and industrial batteries with a capability of over 2 kWh which might be marketed within the EU would require a digital battery passport. The aim is to make sure transparency and sustainability within the battery worth chain, cut back environmental impacts, and encourage the secondary use of batteries. The Battery Go Consortium, with the participation of the Fraunhofer Institute for Manufacturing Techniques and Design Expertise IPK, is growing frameworks and proposals by way of content material and know-how for implementing the passport. Researchers from Fraunhofer IPK are accountable for the design and implementation of the technical requirements. From April 22 to 26, 2024, they are going to be on the Hannover Messe (Corridor 2, Sales space B24) presenting a draft technical reference customary designed to allow battery passports — and all kinds of digital product passports — to be carried out in a method that’s scalable and interoperable.

Batteries are key to the transition to climate-friendly mobility and the widespread use of renewable energies. As essential parts of electrical autos, they must be produced and used sustainably and reincorporated into the fabric cycle simply. It is very important delay the life cycle of the whole battery system as a lot as potential and to recycle the uncooked assets, supplies and parts after they’re first used. Clear provide chains additionally must be fashioned, from the uncooked supplies all the way in which to the meeting of batteries. Sooner or later, producers might want to doc all emissions ensuing from the manufacture, use and disposal of their merchandise. To assist these ambitions, the brand new EU Batteries Act would require a digital passport for all traction batteries, two-wheeled car batteries and industrial batteries with a capability of over 2 kWh from February 2027. This can even have an effect on LMT (gentle technique of transport) batteries constructed into electrical bicycles and electrical scooters.

Transparency across the electrical automobile battery

The aim of the battery passport is to assist seamless documentation of a battery’s life, from uncooked materials extraction and manufacturing to make use of, reuse and recycling. It holds a file of a battery’s origin and logs the related makes use of. To this finish, it paperwork knowledge that comprehensively describes the sustainability and duty of the availability chain, reminiscent of knowledge on the carbon footprint, the working situations for uncooked materials extraction, battery supplies and parts, hazardous substances contained, useful resource effectivity, efficiency and repair life, battery standing, and different knowledge together with info on recyclability and restore in addition to learn how to implement these steps. Disassembly directions contained within the battery passport assist to facilitate the secondary use of as lots of the battery’s parts as potential.

“The battery passport offers a digital file of all the socially, ecologically and economically related info on a battery’s life cycle. By offering verified and verifiable info, it may create transparency, assist second-life makes use of or optimize processing by recycling suppliers. This helps the event of sustainable enterprise fashions alongside the battery worth chain whereas complying with related sustainability and moral standards. The intention is to cut back little one labor and air pollution in nations the place the uncooked supplies are produced and maintain observe of the export of outdated batteries, for instance,” says Prof. Thomas Knothe, a scientist at Fraunhofer IPK, which is a member of the venture consortium (see field) and which attracts up the technical requirements which might be related to business and transforms them into European requirements. To allow battery producers and importers to current the battery passport in 2027, all the mandatory groundwork, technical specs and check techniques should be accomplished by the top of 2025.

Decentralized knowledge

The battery passport takes the type of a software program system the place all knowledge is saved in distributed knowledge areas and duty for the info is decentralized. Sure features, such because the central registration of passports and a so-called Information Portal, which can present an aggregated view of a majority of battery passports, would be the duty of the European Fee. Some knowledge components will solely be made accessible to nationwide authorities’ knowledge techniques for functions reminiscent of market conformity checks. The producer will likely be accountable for managing the remainder of the info. Any adjustments to the battery knowledge will must be up to date within the passport. Every producer should appoint a third-party supplier to make sure that there’s a backup of the info within the occasion of insolvency. The required interfaces, entry rights and features will must be carried out within the software program system. To make sure that this occurs, there are quite a few questions being addressed within the Battery Go Consortium: What battery knowledge will likely be required? Who ought to retailer them, how, when and the place? Who will be capable of entry the info and the way? How will entry to the info be saved safe? How can options incorporate current techniques but additionally new ones? The Battery Go Consortium is proposing current technical requirements in addition to requirements which might be nonetheless to be developed and is illustrating the integrative software of these requirements utilizing a software program demonstrator. “One of many challenges of placing the specs into observe is interoperability,” explains Knothe. For instance, the software program system must assist as many various knowledge carriers as potential, which provide info to the product in a method that’s much like a barcode or QR code. The identical applies to distinctive identifiers, that are like ID numbers assigned uniquely to a product. In addition to this, the system additionally wants to have the ability to symbolize the foundations in numerous nations and be suitable with a variety of knowledge administration applied sciences and platforms. The information necessities of various sectors additionally must be thought of because the battery passport can even be used as a foundation for different passports. “A system like that is too advanced to be pushed by a single firm or perhaps a consortium. That’s why we’ve included a big neighborhood of companions and supporters within the venture actions from an early stage. That additionally provides the system the momentum it wants to realize wider acceptance in observe,” says Knothe.

Battery passport paving the way in which for different product passports

The battery passport is the primary digital product passport to be launched at European stage. It would function a pilot — different passports for merchandise reminiscent of textiles, electronics and constructing supplies are at present within the strategy planning stage to make sure the trade of knowledge in provide and worth chains and compliance with environmental and social requirements. “That is rightly thought of to be an vital pilot for digital product passports extra usually, which will likely be prolonged to different sectors sooner or later and change into more and more vital,” says the researcher.

From April 22 to 26, 2024, the Fraunhofer IPK researchers, along with the venture companions, will likely be on the joint Fraunhofer sales space on the Hannover Messe (Corridor 2, Sales space B24), depicting the ecosystem of a battery with the assistance of a demonstrator and presenting a price stream situation for the manufacture and use of batteries for electrical automobiles. One other demonstrator will likely be exhibiting how the required knowledge is aggregated within the battery passport.
