Digital Battery Passport at Hannover Messe: How explitia Shows the Practical Role of Data in Battery Manufacturing

Until recently, many companies associated the battery passport mainly with regulations, documentation, and yet another compliance requirement to sort out. That is starting to change. The demonstration of the Digital Battery Passport at Hannover Messe is taking on a physical and practical form through a demonstrator developed internationally under the International Manufacturing-X Council (IMXC) initiative.

This is not just about attaching information to a product. It is about making data actually work. It is about helping manufacturers better understand the product, improve collaboration across the supply chain, and manage what happens to a battery from assembly through the next stages of its lifecycle.

That is why Digital Battery Passport stands out so clearly in the context of Hannover Messe 2026. At the event, the topic moves beyond general statements and becomes something tangible.

Visitors will be able to see a digital battery product passport demonstrator that shows the full journey of the product and the cooperation between independent parts of the supply chain.

This is where explitia comes in. We will appear as a partner presenting a specific part of the overall process, delivered together with partners from more than a dozen countries. It is the stage where a finished battery gains not only its physical form, but also a structured data layer.

In battery manufacturing, it is becoming harder to separate the product from the information attached to it. The more complex the supply chain, the more important it becomes for data to be consistent, readable, and ready to be used by the next party in the process.

Just a few years ago, many companies could still operate in a model where some information sat in one system, some in another, some with the supplier, and some outside any shared workflow. That could work when the process was simpler and market expectations were lower.

That is changing.

Transparency matters more. Traceability matters more. Environmental footprint data matters more. The quality of the data exchanged between partners matters more too.

In that environment, the digital battery passport stops being an add-on. It becomes a tool that brings order to information that used to be scattered.

For manufacturers, that creates a very practical benefit: fewer assumptions, less manual work to piece information together from multiple sources, and more control over what is actually known about the product.

Put simply, a Digital Battery Passport is a structured record of a battery and its history. It includes information about components, production stages, environmental footprint, later use, and what happens to the product afterward, such as servicing, second-life use, or recycling.

For manufacturers, it is a way to organize product knowledge so it can be useful not only inside the company, but also in relationships with partners across the value chain.

That is why digital product passports and similar product data models are becoming more important. They are no longer just a compliance topic. They are becoming part of how companies manage quality, responsibility, and the flow of information.

This is what sets the topic apart from many other conversations about industrial digitalization. It is easy to say that data will become more important. It is much harder to show what that change actually looks like in a real process.

The idea of Digital Battery Passport at Hannover Messe, it becomes much clearer, because the point is not just to define what a battery passport is. The point is to show how this model works when real production stages, actual components, and information flows between supply chain participants all come into play.

That makes a big difference.

Instead of hearing another explanation of what Digital Battery Passport means, visitors can see how the product moves through different stages and how its digital history is built alongside it. Data is not added at the end. It is created with the product. Information follows the battery from the beginning instead of trying to describe it after the fact.

For many manufacturers, that is where the real value becomes clear. Not in theory. Not in declarations. In a working example they can relate to their own production environment.

At first glance, this may look like a use case focused on batteries. In reality, it points to something much broader.

It shows how to connect physical manufacturing with data.

In this model, it is not enough for the battery to be assembled correctly. It also matters:

That is what turns the battery passport into part of the production process itself. It is created together with the product and grows alongside it.

This is exactly why the topic matters so much to manufacturers today. It shows that structured data is no longer only about reporting. More and more often, it is part of running a well-organized production process.

explitia’s role in the Manufacturing-X demonstrator at Hannover Messe is not symbolic.

We are designing the stage where individual parts become a finished battery and where distributed information needs to be combined into one consistent view of the product. In other words, this is the point where physical assembly, product structure, and the data needed for downstream processes all come together.

This is where the following meet:

The simplest way to put it is this: someone has to make sure the finished product does not end with the physical layer alone. It also needs a structured data layer that makes business sense and can be used further down the line.

That is the part explitia is presenting at Hannover Messe. Not outside the process, but at its center. Right where the idea stops being abstract and starts becoming part of everyday manufacturing logic.

For some companies, the battery passport may still sound like a distant topic. But the cost of unstructured data is very real.

It means slower access to information. Harder data handoffs between partners. Greater risk of errors. Less visibility into what is actually happening to the product at later stages.

With simpler products, those gaps can sometimes stay hidden. With more complex products, they start becoming expensive.

That is why battery data matters so much. Not because it looks good in presentations, but because without it, it becomes harder to manage quality, collaboration, and the later life of the product in a sensible way.

Today, manufacturers need more than confirmation that a battery was assembled. They also need to know:

This is where the digital battery passport starts showing its real strength.

This is one of the most important shifts now visible in battery manufacturing.

For years, product value was judged mainly by performance, build quality, cost, and availability. Now another question is becoming just as important: what is actually known about the product, and is that information ready to be used?

With batteries, that matters even more. We are talking about a product whose story does not end when it leaves the production line. Later use matters. State of health matters. Decisions about second life matter. Material recovery matters. The broader question of product responsibility matters too.

That is why the battery lifecycle increasingly requires not only a good product, but good product data as well.

In that sense, data is becoming part of the value itself. Not an extra layer. Not a marketing wrapper. A real part of how a company works with the product and collaborates with others.

There is another thread here that matters a lot in manufacturing: how data is shared.

Companies want to collaborate, but they do not want to lose control over their own resources. And that makes sense. Production data is part of their know-how, experience, and operating advantage.

That is why sovereign data sharing in manufacturing is becoming more important. It means a model in which information can move between partners without forcing everyone to hand everything over to one shared place with no clear rules or control.

From a business perspective, that has clear advantages:

That matters even more when a product moves across many hands, systems, and companies. And that is exactly what modern battery manufacturing increasingly looks like.

The biggest shift is not that there is a new term to learn. The real shift is that the market is starting to look at products differently.

Not only as physical goods, but also as structured sets of information that need to keep pace with the actual process and support it at every stage.

That changes how companies think about collaboration, quality, traceability, and product responsibility. It also changes how information exchange between partners needs to work.

That is why the use cases for battery passports are broader than they may seem at first. They go well beyond formal requirements. They start affecting whether a company truly has control over what it knows about its product.

Because it is one of the easiest places to see that this shift is already happening.

Not as a broad industry talking point. Not as a slogan. But as a process you can follow step by step.

That gives visitors something that is often missing from conversations about new standards and new data models: a reference point. A chance to see what this can look like in real manufacturing.

That is valuable, especially for companies that are already trying to organize their data, improve traceability, or connect their work more effectively with partners.

That is also why explitia’s presence in this scenario matters more than simply attending the event. It shows a specific part of a shift that is already affecting manufacturing.

The most interesting part of all this is that Digital Battery Passport is no longer functioning as a separate layer added to the product later. It is starting to be built together with the product itself.

That is the direction shown by the IMXC demonstrator at Hannover Messe. And that is exactly why it is worth paying attention.

For battery manufacturers, what matters more and more is not only what leaves the production line, but whether the data behind the product is just as well organized as the product itself.

Digital Battery Passport is a digital record of a battery and its history. It includes battery data related to components, production, environmental footprint, use, and later lifecycle stages such as servicing, second-life use, and recycling.

A battery passport helps manufacturers manage product information more effectively. It improves access to data, increases process transparency, and supports work with the product across the full battery lifecycle.

At Hannover Messe, Digital Battery Passport is presented as part of a real production process. Visitors can see how component data, assembly data, and environmental footprint information come together in one consistent product record.

explitia presents the stage where individual parts become a finished battery and where distributed information is combined into one consistent product view. This is the point where the physical product and its data layer start working together.

Battery data matters because it supports quality, traceability, and information flow between partners. In modern battery manufacturing, data is becoming part of product value, not just an add-on to documentation.

Battery passport use cases include product traceability, data management, reporting, collaboration across partners, service readiness, recycling support, and second-life battery processes.

No. Regulation is one driver, but the digital battery passport also has operational value. It helps companies organize data better, improve collaboration, and build a more sustainable supply chain.
