Industrial Battery Passports Above 2 kWh

The industrial category is the only one where the much-quoted 2 kWh threshold does any work. It is also the category with the least settled boundary, because industrial use is defined by application rather than by form, and applications change.

What is an industrial battery?

The residual nature of the definition matters. A designer asking whether their battery is industrial is really asking whether it is anything else first, and if the answer is no, the industrial obligations apply provided the capacity threshold is crossed.

How is the 2 kWh threshold measured?

The threshold applies to rated capacity in kilowatt-hours as declared under the applicable measurement standard, and the test is above 2 kWh. A battery rated at exactly 2 kWh is outside the passport obligation, which makes the declared figure a regulatory statement rather than only a commercial one.

This creates an incentive worth naming plainly: a manufacturer close to the boundary has a reason to rate conservatively. That is legitimate where the rating is honest and a problem where it is not, and market surveillance authorities are aware of the incentive.

The harder question is what the battery is. A modular storage system assembled from 2.5 kWh units into a 100 kWh installation raises the question of whether the battery is the module or the system, and the answer changes both the passport count and who issues it.

The workable rule is that the battery is the thing placed on the market as a product. Where modules are sold separately and assembled by an installer, each module is a battery; where a system is sold complete, the system is. On-site integration by a third party can create a further placing on the market, and integrators frequently have not considered this.

What differs from vehicle batteries?

The field list is largely common, but the weight of individual fields shifts substantially with the application.

Durability is where the difference is sharpest. A grid storage asset is contracted on cycles and availability, and its owner is exposed financially to degradation in a way a car owner is not. Passport durability data therefore has direct commercial consequences, and buyers in this segment read it.

Who carries the obligation in a storage project?

Storage projects involve a cell producer, a pack or rack manufacturer, a system integrator, an EPC contractor and an asset owner. The obligation attaches to whoever places the battery on the EU market, and in this chain that is genuinely ambiguous in a way it is not for a car.

• If the integrator imports complete racks and installs them, the importer places them on the market.
• If the integrator assembles a new product from imported modules, it may itself be placing a battery on the market.
• If modules are sold to the asset owner and installed under a separate contract, the module supplier is the operator.
• Where the chain is unclear, the contract should assign the obligation explicitly rather than leaving it to be argued later.

The last point is the practical advice. This is a question of fact rather than agreement, so a contract cannot move the legal duty. It can, however, allocate the cost and the data obligations, and doing so before the project is built is far cheaper than discovering the ambiguity during an inspection.

How does second life interact with this category?

Stationary storage is the most common destination for repurposed vehicle batteries, which puts this category at the receiving end of the second-life question addressed in battery second life and the passport.

Preparation for repurposing is treated as placing a battery on the market again, so the repurposer becomes the responsible operator for a new industrial battery. They inherit whatever history the original passport recorded, which is why the sampling policy on state of health in the vehicle’s life determines whether a second-life asset can be financed.

What about batteries in industrial equipment?

Forklifts, automated guided vehicles and materials-handling equipment carry batteries that are industrial by design purpose. These are frequently large, long-lived, and serviced in place by third parties over many years, which makes dismantling and safe-handling data operationally useful rather than merely compliant.

Fleet operators in this segment already track battery condition for their own reasons, because a failed traction battery stops a warehouse. Much of the state of health data the passport requires therefore already exists; it sits in a maintenance system that nobody has connected to a compliance obligation.

How does the passport affect tendering?

Public and corporate procurement in storage already asks for embodied carbon, recycled content and end-of-life planning, usually through a questionnaire assembled per tender. Those questions are the passport field list in a different order.

Once the passport exists, a bidder can answer them from one record with evidence attached rather than reconstructing figures per bid. That is a genuine commercial return on a compliance obligation, and it arrives before the February 2027 date rather than after it.

It also raises the floor. When one bidder can produce signed supplier evidence for a recycled content figure and another offers an unsupported number, the difference is visible to a procurement team in a way it was not when both were assertions in a spreadsheet.

What does the passport require during operation?

Unlike a vehicle battery, an industrial storage asset is usually monitored continuously by its owner for commercial reasons. State of health, cycle count and availability are already instrumented, because they determine revenue under a capacity or arbitrage contract.

The passport obligation therefore asks for a summary of data that already exists, which is a far easier integration than in consumer categories. The work is deciding what to publish and to whom, since operational detail about a specific site is commercially sensitive and the restricted access tier exists precisely for this.

A sensible split publishes design durability and chemistry openly, keeps measured performance in the restricted tier for legitimate interested parties and the Commission, and records interventions as dated events so that a later owner can reconstruct what happened to the asset.

What happens at decommissioning?

Industrial batteries are decommissioned as projects rather than as individual products, often years after the manufacturer relationship has ended and sometimes after that manufacturer has left the market. The passport is frequently the only surviving description of what is being taken apart.

That is the strongest argument for the standards-based approach: a record expressed in GS1 and W3C specifications can be resolved by any conforming service, whereas a proprietary portal depends on one company still existing in fifteen years. For an asset with a twenty-year design life, this is not a theoretical concern.

Decommissioning also produces the second-life supply that the same category then consumes. A pack whose degradation history is documented can be assessed quickly and repurposed; one whose history is missing is assessed from scratch or sent to recycling, which is the outcome the whole regime is trying to make less common.

What should an industrial battery programme do first?

Settle what the product is before anything else. The threshold question and the placing-on-market question both depend on identifying the unit sold, and every downstream decision — how many passports, who issues them, which supplier holds which field — follows from that answer.

After that the sequence matches any other battery programme: confirm scope against the tests in which batteries need a passport, map the field list from battery passport data fields onto the parties that hold each figure, and start the supplier conversations that will take a quarter or more to produce evidence.

The category-specific addition is durability. Because industrial buyers contract on cycles and availability, durability parameters should be treated as a commercial deliverable rather than a compliance field, which usually means engineering owns them rather than compliance.
