Can I keep my battery passport up to date myself?
Yes, you can, provided you know which data must remain correct and you have a way to change them without the QR code or the link to the passport changing. It is not about filling in a passport once, but about maintaining it as long as the battery is on the market: changes in composition, in component suppliers, in repair or recycling information, or corrections to previously entered data.
Whether updating yourself is practical in practice depends on three things: how many product variants you have, how often the underlying data changes, and whether there is someone in your organisation who understands the technical side — because once a passport is online, it must also be accessible via the same QR code after an update. With a small, stable assortment, that is manageable. With a broad or rapidly changing assortment, it quickly becomes a recurring task that is easily forgotten.
What exactly needs to be kept up to date
The regulation describes what data a battery passport must contain, but does not say that this data is static. An importer who switches suppliers, a manufacturer who adjusts a cell type, or a company that later discovers an error in previously supplied data: in all these cases the content of the passport changes, while the product that is already with the customer remains the same. Who is responsible for that update depends on the role you have in the chain — manufacturers, importers and distributors do not automatically have the same obligations in this respect. selected background information by subject provides an overview of this, tailored to the situation you recognise yourself in.
What doing it yourself requires in practice
Keeping a passport up to date yourself basically means having three things in order. First, an internal process: who identifies that something has changed with a product, and who ensures that this is implemented in the passport. Second, a technical environment that allows this without you having to print and distribute a new QR code for each change. And third, someone who understands which changes fall under the reporting obligation and which do not — not every adjustment is equally relevant for the end user or for supervision. Without these three elements, there is a risk that a passport will no longer match the product the QR code is on over time, which is precisely what supervisory authorities may encounter during inspections.
Where the boundary between doing it yourself and outsourcing lies
There is no fixed threshold above which doing it yourself is no longer possible; it is a matter of weighing the size of your assortment, the frequency of changes and the time you can spend on it internally. A company with a handful of product types and a stable supply chain can easily organise the update itself, as long as someone is responsible and the technology allows it. A company with dozens of variants, seasonal assortment changes or a chain with multiple suppliers is more likely to run up against the limits of what is internally feasible, simply because maintaining it then becomes an ongoing task rather than a one-off project.
If you are unsure whether your own situation lends itself to self-management, it is best to make that question concrete: how many passports are there, how often does the underlying data change, and is there capacity to maintain that structurally. see in a few questions where you stand provides a first indication of this, without you needing an account for it immediately.
What a hosting partner can and cannot solve in this
A platform that hosts the passport takes the technical side of updating off your hands: the QR code remains the same, even if the underlying data changes, and the update is carried out in the background. That does not change the question of who is responsible for the accuracy of the data — that responsibility lies with the party placing the battery on the market, not with the hosting party. What such a party does solve is the risk that an update gets stuck in an internal process that nobody monitors anymore. On batpas.eu we explain precisely how the supplied data is processed and maintained so that you can assess whether that aligns with what you already do or precisely want to outsource.
Whether managing it yourself is the right choice for your company is ultimately a question you can best answer based on your own product range and organization, and in case of doubt about the obligations themselves consult a lawyer or the competent supervisory authority.
