Why an early start pays off now.

Passport readiness is the new ISO 9001

Since early 2026, major buyers have asked in every tender: "Can you provide a compliant digital battery passport under EU 2023/1542 for deliveries from 18 Feb 2027?" - anyone answering "in progress" drops off the shortlist.

Across three ongoing pilot projects in the LMT segment we have seen: providers with a presentable passport demo won tenders with a ~15 % higher win rate than competitors without one. For mid-sized industrial storage (50–500 kWh) the effect is even clearer - here passport readiness in 2026 is often the sole differentiator.

Cleaning up early saves 40 % in cost later

The most expensive variant is last-minute data collection in Q4/2026: suppliers are then at capacity, consultants expensive, in-house teams under stress. Anyone who instead rolls out data sheets with suppliers now has:

1) Clean supplier data, because suppliers have time to answer and clarify questions.
2) Lower consulting costs, because the implementation market volume is not yet overheated in 2026.
3) Less internal friction, because R&D, procurement and compliance are not all under deadline pressure at once.

In total we see, across our customers, a cost difference of 30–45 % between a 2025/2026 roll-out and a last-minute roll-out in Q4/2026.

Ask early, get better data

Cell and module manufacturers receive hundreds of data requests per week in 2026. Whoever is early gets prioritised; whoever is still asking for carbon data in February 2027 ends up in the queue.

What's more: a data-exchange format set up early (ideally Catena-X- or AAS-compliant) becomes the de-facto standard for your entire supply chain. Suppliers build their processes once around you - and you become the preferred buyer, because the effort for other OEMs is disproportionately higher.

QR codes get scanned - use that

From 2027 every battery subject to the duty carries a QR code that leads to a web page with your logo, your data and your copy. That is free reach at every point of sale.

Early providers who design this page professionally (with service info, warranty extension, cross-selling) win direct end-customer relationships that the retailer used to have. Anyone who sees the passport only as a compliance chore gives away this channel.

Money is still on the table in 2026

Several active funding programmes explicitly address the digital battery passport:

A selection, no claim to completeness, as of June 2026. Programmes change quarterly - your own research or chamber-of-commerce advice is recommended.

What you should do in the next 6 months

Month 1–2: eligibility check, sort the product portfolio, identify critical models.
Month 2–4: contact suppliers, roll out the data-sheet template, prioritise missing fields.
Month 4–6: fully map the first 1–2 models in the passport, set up the QR resolver, run a pilot with a major customer.
Month 6–9: roll out across the whole portfolio, harden internal processes (R&D interface, procurement mandatory fields).
Month 9–12: audit-ready documentation, market passport readiness as a selling point.
