Why energy storage is the most demanding case
Modular systems, purchased cells and second-life concepts create complex data flows. Structured capture creates the biggest advantage here.
Modular architecture
Storage systems consist of modules, racks and packs. The passport applies per battery placed on the market.
State and lifetime
Capacity, cycle life and temperature ranges belong in performance and durability - structured instead of hidden in PDFs.
Reuse and refurbishment
Refurbished batteries receive a new passport linked to the original one.
Model-level carbon footprint
LCA balance, performance class and lifecycle stages captured in a structured way.
Purchased cells
Cell chemistry and raw-material origin often come from suppliers. Share links let partners provide data directly.
Labeling on housing
Each published product gets a public URL and downloadable QR code (PNG or SVG).

Frequently asked questions about storage battery passports
Does the battery passport requirement apply to home storage?
Yes. Home storage batteries are considered industrial batteries. From 2 kWh, the battery passport requirement applies from 18 February 2027.
Do existing storage installations need retrofitting?
No. The requirement only applies to batteries newly placed on the market from 18 February 2027.
How does this work for systems with multiple modules?
The passport applies per battery placed on the market. Exact implementation details depend on how the battery is placed on market. The underlying data structure is explained on the DIN SPEC 99100 software page.
What applies to second-life and refurbished storage?
Reused or refurbished batteries receive a new battery passport linked to the original one.
