Battery passport FAQ
Do I need a battery passport? What to prepare before 18 Feb 2027? Who is responsible, where is data kept, what does it cost? Plain answers.
Do I need one?
Does my battery need a battery passport?
From 18 February 2027, LMT batteries (such as e-bike batteries), EV batteries and industrial batteries above 2 kWh — including home storage — need a battery passport to be placed on the EU market. Batteries that do not need one still need a QR code. If you are unsure where your product falls, contact us. Nothing on this site is legal advice.
Which category is a home storage battery, and does it need a passport?
It is an industrial battery, wherever it is installed and whatever it weighs: recital 15 of the Battery Regulation says batteries used for energy storage in private or domestic environments count as industrial batteries. Above 2 kWh it needs a passport from 18 February 2027; up to 2 kWh it needs a QR code. See industrial batteries and home storage.
Does an e-bike battery always need a passport?
Yes. An LMT battery needs a battery passport from 18 February 2027 whatever its capacity (Art. 77(1)). A traction battery weighing 25 kg or less is an LMT battery. See LMT batteries.
What about a battery of exactly 2 kWh?
No passport. The regulation says “greater than 2 kWh”, so an industrial battery of exactly 2 kWh or less needs no passport — but it needs a QR code from the same day.
Does a portable power station need a passport?
It depends on weight and capacity. Above 5 kg it is generally treated as an industrial battery, and above 2 kWh that means a passport. Up to 5 kg it is generally a portable battery: no passport, but a QR code. Whether a power station is “stationary storage” is not spelled out in the regulation, so ask an expert if it is unclear, or contact us.
What do batteries that need no passport still need?
From 18 February 2027 every battery carries a QR code (Art. 13(6)). For batteries without a passport it points to a page with label and compliance information — we call it a QR information page. See no passport needed.
Is what I read on this site legal advice?
No. Every statement on this site names the article behind it, but the articles and guides are for reference only and are not legal advice; if a case is unclear, ask an expert.
How to do it, what to prepare
What should I prepare before 18 February 2027?
Work out the category of each model; gather spec sheets, test reports and safety data sheets; fill and check the passport data; decide who places the batteries on the EU market (your importer or you; an authorised representative only acts within its written mandate); publish the passport and print the QR code on the battery. Once the EU registry opens for batteries, register there too.
I only have spec sheets and test reports. Is that enough?
It is a good start. Upload spec sheets, test reports and safety data sheets to the workspace; the AI reads the values and notes the page each came from, and nothing counts until you confirm it. What cannot be read is listed; some of it only your cell or material suppliers have, and you can send them a link to fill in on their phone.
What if a supplier doesn’t cooperate?
The platform lists what to ask for, makes a link that needs no sign-up, and reminds the supplier before the deadline. Data that comes back is marked with its source and only used after you confirm it. Whether a supplier is willing is up to your relationship; we make it easy for them.
Can I register battery passports in the EU registry today?
Not yet. Once the EU registry opens for batteries, the economic operator that places the battery on the market registers the passport ID. Our EU registration prep wizard already walks you through the documents and the electronic seal and generates the files; we will connect as soon as the registry opens.
Do I enter the battery passport registration identifier in the customs declaration?
No. For other products under the Ecodesign Regulation (ESPR) the identifier goes into the customs declaration; for battery passports it does not. The passport must still be registered in the EU registry. (Commission battery passport FAQ 4.1)
Where does the QR code go?
Printed or engraved on the battery, as the Battery Regulation requires; where the nature or size of the battery does not allow that, on the packaging and the documents that come with it (Art. 13(7)). The platform makes the unique ID and the QR code of each battery and gives you label files ready for printing, after checking the size and the quiet zone.
Who is responsible, what the rules say
Who is responsible for the passport content?
The economic operator that places the battery on the EU market (Battery Regulation, Art. 77(4)). PassBridge hosts and checks the passports; legal steps such as publishing are confirmed by your compliance lead.
I am a Chinese factory. Does my EU importer need the platform too?
Not necessarily. You can build the passport on the platform and your importer places the battery on the market as the economic operator. The importer can get the passports of its own batteries and download the registration files. See EU importers.
If I authorise someone in writing to make the passport, does the responsibility move to them?
No. The economic operator may authorise a factory, a cell maker or a service provider in writing to create and update the passport, but the ultimate legal responsibility stays with the economic operator placing the battery on the EU market, and so does registering it in the EU registry. Authorising a Chinese factory to make the passport does not make that factory an EU manufacturer or importer. (Battery Regulation Art. 77(4); Commission battery passport FAQ 2.1, 2.2, 2.4)
Battery packs are exported to the EU and assembled into a complete system there. Who makes the passport?
The company that assembles them in the EU into a finished, safely working battery and places it on the market or puts it into service. Packs, modules or cells imported as components, before they are a finished battery, generally need no passport; the duty starts when the finished battery is placed on the market. (Commission battery passport FAQ 2.5, 3.4, 4.3)
If I use the platform, am I compliant?
The platform helps you build and keep your passports by the rules and checks every field before publishing. But under the Battery Regulation the company placing the battery on the EU market is responsible for the passport content (Art. 77(4)). We do not promise compliance; our articles and guides are for reference and are not legal advice.
Has the EU endorsed the platform?
No. PassBridge is a service provider that turned the Battery Regulation and related rules into checks. It is not an EU body and has no official EU approval or certification. This site does not use words like “official” or “certified”.
Which data goes into a passport?
The Commission's guidance on battery passport data points lists 71 data points; following the passport data model (schema), the platform checks them as 92 fields. How many apply depends on the battery category, and some need not be filled in February 2027; the platform marks them. The guidance (version 3.2, 19 October 2026) helps to read the regulation but is not law. The battery semantic catalogue the EU registry will use to check passport content has not been published yet. See Which data goes in a battery passport.
Data and AI
Will the AI fill in or publish my passport?
No. In the workspace the AI reads your documents and marks each value as an “AI draft” with the page it came from. Nothing counts until you confirm it, and the AI cannot publish, delete or register anything. Which model is used will be stated in the AI services notice published with the workspace.
Will restricted data show on the public page?
No. The public page only shows what may be public. Dismantling details, battery status and usage data are only for authorised parties who log in to the access portal.
Where is my data stored?
The workspace runs in mainland China. Published passports are hosted on our passport hosting service (Hong Kong node). Source documents, bills of materials and supplier data stay in the workspace and never leave with the passport. If you need it, ask us about passport hosting on the EU node.
Which AI model is used? Is my data used for training?
Which model, its filing status and how long data is kept will be stated in the AI services notice published with the workspace, which is what counts. This website itself has no AI chat.
If my company closes, can people still scan published passports?
Yes. A battery passport has to be available during the whole life of the battery, so we keep already published passports online and scannable. See security and data.
My battery is not connected. How is the dynamic data in the passport updated?
Not in real time. The Commission explains that dynamic data must at least be updated when the battery's status changes or a change is being considered, for example when deciding whether to remanufacture, repurpose or recycle it. An e-bike battery that is not connected can be updated when it comes in for servicing or repair. (Commission battery passport FAQ 8.3, 8.4, 8.7)
