Annex XIII: What Data You Need

Annex XIII of the EU Battery Regulation defines the mandatory data fields for every battery passport. DPP Cloud organises these fields into four accordion sections in the passport creation wizard.

The four data sections

Identity & Origin

The fields that identify the battery and trace its origin. These are completed first and include:

• Manufacturer name — the legal name of the battery manufacturer. Required.
• Manufacturing place — city and country where the battery was produced. Required.
• Manufacturing date — the date the battery was manufactured. Required.
• Battery model number — the manufacturer's internal model identifier. Optional but recommended.
• Battery chemistry — the cell chemistry (e.g., NMC, LFP, NCA). Required.
• Rated capacity — nominal capacity in Ah or kWh. Required.

Performance

Technical performance data derived from testing under the regulation's reference conditions:

• Rated capacity (Ah) — the nominal capacity in ampere-hours. Required.
• Nominal voltage (V) — the nominal voltage of the battery. Required.
• Energy density (Wh/kg) — gravimetric energy density. Required for EV batteries.
• Cycle life — the number of charge-discharge cycles the battery can perform before reaching 80% of rated capacity. Required.
• Expected lifetime (years) — the expected service life under reference conditions. Required.

Sustainability

Environmental and material composition data:

• Carbon footprint (kg CO₂e/kWh) — the lifecycle carbon footprint. Required. See the carbon footprint article for detail.
• Carbon footprint performance class — a letter grade (A through E) indicating how the battery compares to the EU-wide benchmark. Required once the Commission publishes the benchmark.
• Recycled content — cobalt (%) — the percentage of cobalt from recycled sources. Required from 2031.
• Recycled content — lithium (%) — the percentage of lithium from recycled sources. Required from 2031.
• Recycled content — nickel (%) — the percentage of nickel from recycled sources. Required from 2031.
• Recycled content — lead (%) — the percentage of lead from recycled sources. Required from 2031.

Supply Chain

Information about the economic operators involved in the battery's lifecycle:

• Supply chain actors — the organisations in the supply chain, from raw material extraction through cell manufacturing and assembly. Required.
• Due diligence declaration — confirmation that supply chain due diligence has been conducted in accordance with Article 52. Required.
• Third-party audit — whether the due diligence has been independently verified. Optional but affects compliance strength.

Required vs optional fields

Each field in DPP Cloud is marked as either Required (purple label) or Optional (grey label). Required fields must be completed before you can activate the passport. Optional fields improve your compliance strength score but are not mandatory for activation.
