# Dippia

> Dippia is a web application for the battery passport the EU asks for from 18 February 2027: one record per battery, its history, and the public page behind its QR code.

Dippia is for the economic operators the regulation makes responsible for a battery passport: battery manufacturers, EU importers and others that place batteries on the EU market. The rule is Article 77 of Regulation (EU) 2023/1542: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32023R1542

What Dippia does today (last checked on 2026-09-19):

- Battery models and a passport for each battery, with every version kept
- The lifecycle, with a trail of who recorded what: placed on the market, repair, change of owner, second life, waste, recycled
- A public page for each battery at a permanent address, and the QR code for it
- The three levels of access the regulation sets, and a way to give a named person more than the public sees
- CSV import with a preview: every row is written, or none
- Teams with three roles, joined by invitation
- Sign-in with a verified email address, and an authenticator app if you want one
- A server in Germany, with backups that are encrypted and kept in the EU
- A light and a dark theme

Questions and answers:

- **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.
- **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.
- **Does Dippia register passports in the EU’s registry?** Not yet. Registering passports in the EU’s digital product passport registry is planned and is not available today.
- **What can Dippia not do yet?** Planned, and not available today: registering passports in the EU’s digital product passport registry; an API for your own systems; the other official EU languages, and Chinese, Japanese, Korean and Vietnamese; passports on your own domain; keeping passports reachable without us, with an export you can take away. Documents such as a declaration of conformity are links today, because we do not store files yet. The application is in English, Français and no other language yet; this site is in English only.
- **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. What we have today: a passport’s address holds only the battery’s ID, so the addresses can move to another host, and the backups are kept away from the server. What we have not built yet: an export you can take away, and a way to keep passports reachable without us. Both are planned.
- **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.
