Beginning in February 2027, all new traction batteries, two-wheeled car batteries, and industrial batteries with a capability of over 2 kWh which can 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 Methods and Design Expertise IPK, is creating frameworks and proposals when it comes to 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 forms of digital product passports — to be applied 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. You will need to extend the life cycle of the complete battery system as a lot as doable 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 may 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 document 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 provision chain, corresponding to information 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 information together with info on recyclability and restore in addition to implement these steps. Disassembly directions contained within the battery passport assist to facilitate the secondary use of as most of the battery’s parts as doable.
“The battery passport gives a digital document of the entire socially, ecologically and economically related info on a battery’s life cycle. By offering verified and verifiable info, it could actually 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 purpose is to cut back baby labor and air pollution in nations the place the uncooked supplies are produced and preserve observe of the export of previous batteries, for instance,” says Prof. Thomas Knothe, a scientist at Fraunhofer IPK, which is a member of the mission consortium (see field) and which pulls up the technical requirements which can be related to trade and transforms them into European requirements. To allow battery producers and importers to current the battery passport in 2027, the entire mandatory groundwork, technical specs and check programs have to 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 information is decentralized. Sure features, such because the central registration of passports and a so-called Knowledge Portal, which is able to present an aggregated view of a majority of battery passports, would be the accountability of the European Fee. Some information components will solely be made accessible to nationwide authorities’ information programs for functions corresponding to market conformity checks. The producer will probably be accountable for managing the remainder of the information. Any adjustments to the battery information 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 information within the occasion of insolvency. The required interfaces, entry rights and features will must be applied 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 information will probably be required? Who ought to retailer them, how, when and the place? Who will be capable to entry the information and the way? How will entry to the information be stored safe? How can options incorporate current programs but in addition new ones? The Battery Go Consortium is proposing current technical requirements in addition to requirements which can be nonetheless to be developed and is illustrating the integrative utility 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 assist as many alternative information carriers as doable, 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 characterize the foundations in several nations and be suitable with a spread of information administration applied sciences and platforms. The info necessities of various sectors additionally must be thought of because the battery passport may 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 mission actions from an early stage. That additionally provides the system the momentum it wants to achieve wider acceptance in apply,” 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 degree. It should function a pilot — different passports for merchandise corresponding to textiles, electronics and constructing supplies are presently within the starting stage to make sure the trade of information in provide and worth chains and compliance with environmental and social requirements. “That is rightly thought of to be an necessary pilot for digital product passports extra usually, which will probably be prolonged to different sectors sooner or later and develop into more and more necessary,” says the researcher.
From April 22 to 26, 2024, the Fraunhofer IPK researchers, along with the mission companions, will probably 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 worth stream situation for the manufacture and use of batteries for electrical automobiles. One other demonstrator will probably be displaying how the required information is aggregated within the battery passport.
