Battery passports for the EU market
One record for every battery you place on the market, the QR code that goes on its label, and the page that code opens.
For the manufacturers, importers and other economic operators responsible under Article 77 of Regulation (EU) 2023/1542: electric vehicle batteries, batteries for light means of transport, and industrial batteries above 2 kWh. Read it on EUR-Lex

Every field, and where it is asked for
The list below is not a brochure: it is counted from the schema the application validates against, so it can hold no field the product has not got. What every battery of a model shares is entered once.
The model: 43 fields, entered once
| Group | Fields | Asked for in | Seen by |
|---|---|---|---|
| Manufacturer | Fields 3 | Asked for in Annex VI, Part A | Seen by Public |
| Materials and chemistry | Fields 6 | Asked for in Annex VI, Part A · Annex XIII, 2 | Seen by Public · Legitimate interest and authorities |
| Performance and durability | Fields 17 | Asked for in Annex XIII, 1 | Seen by Public |
| Carbon footprint and recycled content | Fields 8 | Asked for in Annex XIII, 1 | Seen by Public |
| Due diligence and conformity | Fields 4 | Asked for in Annex XIII, 1 · Annex XIII, 3 | Seen by Public · Authorities only |
| End of life, dismantling and safety | Fields 5 | Asked for in Annex XIII, 1 · Annex XIII, 2 | Seen by Public · Legitimate interest and authorities |
The battery: 21 fields of its own
| Group | Fields | Asked for in | Seen by |
|---|---|---|---|
| Manufacture | Fields 4 | Asked for in Annex VI, Part A · Art. 77 · Regulation (EU) 2024/1781, Art. 12 | Seen by Public · Authorities only |
| Performance when placed on the market | Fields 4 | Asked for in Annex XIII, 4 | Seen by Legitimate interest only |
| State of health | Fields 5 | Asked for in Annex XIII, 4 | Seen by Legitimate interest only |
| Use and events | Fields 8 | Asked for in Annex XIII, 4 | Seen by Legitimate interest only |
A battery can be placed on the market once the label information of Annex VI is there. Everything else is asked for, shown as not filled in yet, and holds nothing up.
Everyone sees their part, and no more
Article 77(2) names three readers outside your team. Dippia sorts every field between them, and counts them here from the same rule it applies when it answers a passport.
-
Anyone who scans the code
40 of 64 fields
No account, no app: the public part of Annex XIII, at an address that never changes.
- Chemistry
- Carbon footprint
- Recycled cobalt
- Detailed composition
- State of health
-
A repairer or recycler you approve
62 of 64 fields
A person with a legitimate interest: a repairer, a recycler, a second-life operator. An admin names their email address, and they sign in to read.
- Detailed composition
- Dismantling information
- State of health
- Results of compliance test reports
The levels are not a ladder. Authorities read points 1 to 3 of Annex XIII; what happened to an individual battery is point 4, and that is for people with a legitimate interest. Dippia follows that, not the shorter story.
What a visitor may not see is filtered out before the page is built, so no template can let it slip. Your own team sees everything of yours, and no other company on Dippia sees any of it.
From your data to the label, in four steps
You can do the whole of it today, for one battery, before you decide anything.
-
Step 1
Describe the battery model
The maker, the chemistry, the capacity, the carbon footprint, the recycled content: what the regulation asks about the model (Annex XIII).
-
Step 2
Add the batteries
One by one, or as a CSV file of up to 2000 rows. We check the whole file and show you what we found before anything is saved. If one row is wrong, nothing is written, and we tell you the line and the column.
-
Step 3
Place them on the market
Each battery’s passport becomes a public page at an address that never changes. We draw the QR code for that address; printing it on the label is your step.
-
Step 4
Keep the record as the battery lives
A repair, a new owner, a second life, waste, recycling: you record what happened, and the passport follows.
A record that holds
You stay responsible for what your passports say. So the record has to show what changed, when, and who changed it.
-
Nothing is overwritten
Every change is a new version that says who made it and when. Earlier versions are never edited and never deleted: the database itself refuses.
-
A lifecycle with a trail
Placed on the market, repaired, a new owner, waste, recycled: each event keeps the day it happened and who recorded it. A battery’s state follows the event, and cannot be set by hand.
-
A second life, a second passport
A battery that is repurposed, re-used or remanufactured gets a new passport linked to the first one, as the regulation asks.
-
Mistakes have a way out
A draft made by mistake can be discarded. A passport that is on the market is corrected with a new version, and the earlier one stays on record.
Where your data is, and who gets in
-
In the EU
Our server and its database are in Germany. Backups are encrypted before they leave the server, and they are kept in the EU.
-
Addresses nobody can walk
A passport’s public address holds 75 random bits and nothing else: no company, no model, no date, no counter. Knowing one tells a stranger nothing about the next.
-
Your team, with roles
Admins, editors and viewers. People join by invitation, sent to the email address you name.
-
Nothing from anyone else
An account needs a verified email address. A page here asks nothing of another company: no font host, no outside script, no analytics, no tracker.

Questions people ask
-
What is a battery passport?
- An electronic record for one battery, required by Regulation (EU) 2023/1542 (Article 77). It holds information about the battery model and about the individual battery, and people reach it through a QR code on the battery. Part of it is public. Part is only for authorities, or for people with a legitimate interest such as repairers and recyclers.
-
Who needs a battery passport, and from when?
- From 18 February 2027, each battery for light means of transport (LMT), each industrial battery with a capacity greater than 2 kWh and each electric vehicle battery that is placed on the EU market or put into service. The economic operator that places the battery on the market must keep the passport accurate, complete and up to date, and may authorise another operator in writing to act on its behalf.
-
What does Dippia do?
- Dippia is a web application where manufacturers, importers and other economic operators create battery passports, keep them up to date through each battery’s life, and publish the page that the QR code on the battery leads to.
-
Who can see what is in a passport?
- The regulation sets three levels (Annex XIII): information for everyone, information for people with a legitimate interest, and information for notified bodies, market surveillance authorities and the Commission. Anyone who scans the QR code sees the public part. For the rest, an admin of your team gives access to a named email address, and that person signs in to read it.
-
Can our plant outside Europe use it?
- The application is in 28 languages, Chinese, Japanese, Korean and Vietnamese among them, and so is every public passport. A page asks nothing of anyone but us — no font host, no script from another company, no analytics, no tracker — so there is nothing on it for a network in between to hold up. Neither a battery’s public passport nor this page needs JavaScript to be read.
-
Where is our data kept?
- On our server in Germany. The database is backed up continuously. Backups are encrypted before they leave the server and are kept in the EU.
-
What happens when a battery is repaired, sold on, reused or recycled?
- You record the event and the passport follows. A repair or a change of owner is added to the battery’s history. A battery that is repurposed, re-used or remanufactured gets a new passport linked to the first one. After recycling the passport ceases to exist, as the regulation says, and its public address says so.
-
Can we bring in our batteries from a spreadsheet?
- Yes, as CSV files of up to 2000 rows. We check the whole file first and show you what we found, by line and column. Nothing is saved until you confirm, and then every row is written or none.
-
What happens to our passports if Dippia stops?
- The regulation asks that a passport remains available even after the company responsible for it has ceased to exist (Article 78), so it must not depend on us either. A passport’s address holds only the battery’s ID and nothing about us, so those addresses can move to another host; the data is kept in the EU and backed up away from the server. Ask us before you rely on it for a fleet, and we will tell you where that work stands.
-
What does Dippia cost?
- We have not published prices yet.
-
How do we start?
- Create an account with your email address and name your company. Then add a battery model and one battery: the first page you see takes you through it, step by step. Your colleagues join by invitation.
Start with one battery
Create an account, add a battery model and one battery, and look at its passport before you decide anything.
