In 102 days a device becomes a data record

2.7 kWh is not a marketing figure. It is a class boundary. From 18 February 2027, every unit above 2 kWh placed on the EU market needs a battery passport — a 29 kg unit is not hand luggage, but from then on it needs an identity document.

What happens on that date

Regulation (EU) 2023/1542 governs the entire life cycle of batteries. It entered into force on 17 August 2023 and has applied since 18 February 2024; the European Commission groups it into five categories: portable, LMT (e-bikes, e-scooters), EV, industrial and SLI batteries.

The battery passport is set out in Article 77 and becomes mandatory on 18 February 2027 — for LMT batteries, EV batteries and industrial batteries with a capacity above 2 kWh. The data points the electronic record must contain are listed in Annex XIII. The passport is reached through a QR code on the unit.

Why 29 kg decides the category

Treating a 2.7 kWh unit as a portable battery because it looks portable misreads the definition. A portable battery is sealed, under 5 kg, and not designed for industrial use, EV, LMT or SLI. A unit with 2.7 kWh and 29 kg does not qualify.

It falls in through the residual class: under Article 3(13), an industrial battery is also any battery weighing more than 5 kg that is neither an EV, LMT nor SLI battery. The 29 kg therefore decide the category; the 2.7 kWh decide only in a second step whether the Article 77 passport also applies.

Who issues the passport — and who does not

The passport attaches to placing on the market, not to manufacturing. The responsible party is the economic operator that places the unit on the EU market or puts it into service. Anyone importing under their own name is that operator — not the factory that soldered the cells.

This is where the expensive mistake happens. Purchasing negotiates unit price and lead time, and nobody asks who keeps the record once the first batch sits in the warehouse. The passport is not a product feature you order alongside an IP rating.

The case that matters

Forty units go to a rental fleet, decal from the customer, invoice from the importer. Two years later an authority asks for the record covering that exact series. The factory can supply the test report and the serial-number allocation — it cannot supply the Article 77 passport, because it is not the economic operator that placed the unit on the market.

That gap cannot be closed after the fact. It is created the moment the first unit is sold.

What to settle in the next 102 days

1. Who is the economic operator — importer, brand owner or dealer? That answer decides who keeps the record.

2. Which data points already exist — serial number, cell chemistry, capacity, power, test reports. Whatever is missing has to come from the factory before it is needed.

3. Where the QR code sits — on the housing, on the label or in the document. A passport nobody can find does not satisfy Article 77.

We supply the technical data, the test reports and the serial-number allocation. The role of economic operator and the record itself sit with the importer — that is not an excuse, it is the structure of the regulation, and it can be settled beforehand or repaired afterwards.
