Beginning in February 2027, all new traction batteries, two-wheeled car batteries, and industrial batteries with a capability of over 2 kWh which are marketed within the EU would require a digital battery passport. The aim is to make sure transparency and sustainability within the battery worth chain, scale back environmental impacts, and encourage the secondary use of batteries. The Battery Cross Consortium, with the participation of the Fraunhofer Institute for Manufacturing Programs and Design Technology IPK, is growing frameworks and suggestions 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 varieties of digital product passports — to be carried out in a manner that’s scalable and interoperable.
Batteries are key to the transition to climate-friendly mobility and the widespread use of renewable energies. As essential elements of electrical autos, they should be produced and used sustainably and reincorporated into the fabric cycle simply. You will need to delay the life cycle of your complete battery system as a lot as attainable and to recycle the uncooked assets, supplies and elements after they’re first used. Clear provide chains additionally should be shaped, from the uncooked supplies all the best way 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 help 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 will even have an effect on LMT (gentle technique of transport) batteries constructed into electrical bicycles and electrical scooters.
Transparency across the electrical automotive battery
The aim of the battery passport is to help seamless documentation of a battery’s life, from uncooked materials extraction and manufacturing to make use of, reuse and recycling. It holds a report of a battery’s origin and logs the related makes use of. To this finish, it paperwork information that comprehensively describes the sustainability and accountability of the availability chain, similar to information on the carbon footprint, the working situations for uncooked materials extraction, battery supplies and elements, hazardous substances contained, useful resource effectivity, efficiency and repair life, battery standing, and different information together with info on recyclability and restore in addition to methods to implement these steps. Disassembly directions contained within the battery passport assist to facilitate the secondary use of as most of the battery’s elements as attainable.
“The battery passport supplies a digital report of all the socially, ecologically and economically related info on a battery’s life cycle. By offering verified and verifiable info, it will probably create transparency, help 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 scale back little one labor and air pollution in international locations the place the uncooked supplies are produced and maintain monitor of the export of outdated batteries, for instance,” says Prof. Thomas Knothe, a scientist at Fraunhofer IPK, which is a member of the challenge consortium (see field) and which pulls up the technical requirements which are related to trade 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 take a look at techniques should be accomplished by the top of 2025.
Decentralized information
The battery passport takes the type of a software program system the place all information is saved in distributed information areas and accountability for the info is decentralized. Sure capabilities, such because the central registration of passports and a so-called Knowledge Portal, which can present an aggregated view of a majority of battery passports, would be the accountability of the European Fee. Some information parts will solely be made accessible to nationwide authorities’ information techniques for functions similar to market conformity checks. The producer can be accountable for managing the remainder of the info. Any modifications to the battery information will should 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 capabilities will should 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 Cross Consortium: What battery information can be required? Who ought to retailer them, how, when and the place? Who will have the ability to entry the info and the way? How will entry to the info be stored safe? How can options incorporate current techniques but additionally new ones? The Battery Cross Consortium is proposing current technical requirements in addition to requirements which are 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 apply is interoperability,” explains Knothe. For instance, the software program system must help as many various information carriers as attainable, which provide info to the product in a manner that’s just 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 characterize the foundations in several international locations and be appropriate with a variety of knowledge administration applied sciences and platforms. The information necessities of various sectors additionally should be thought of because the battery passport will even be used as a foundation for different passports. “A system like that is too complicated 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 challenge actions from an early stage. That additionally offers the system the momentum it wants to realize wider acceptance in apply,” says Knothe.
Battery passport paving the best way for different product passports
The battery passport is the primary digital product passport to be launched at European degree. It would function a pilot — different passports for merchandise similar to textiles, electronics and constructing supplies are presently within the strategy planning stage to make sure the alternate 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 typically, which can be prolonged to different sectors sooner or later and turn out to be more and more vital,” says the researcher.
From April 22 to 26, 2024, the Fraunhofer IPK researchers, along with the challenge companions, can 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 state of affairs for the manufacture and use of batteries for electrical vehicles. One other demonstrator can be exhibiting how the required information is aggregated within the battery passport.
