DIN DKE SPEC 99100 Battery Data Attribute

The DIN DKE SPEC 99100, titled "Requirements for Data Attributes of the Battery Passport," is a standard published in January 2025 by the German Institute for Standardization (DIN) and the German Commission for Electrical, Electronic & Information Technologies (DKE). Developed in collaboration with the Battery Pass consortium, this specification provides practical guidance for companies implementing the digital battery passport, a requirement under the EU Battery Regulation effective from February 2027. The standard defines a comprehensive set of data attributes to ensure transparency, sustainability, and compliance across the battery lifecycle—from raw material sourcing to end-of-life management.

The Battery Data Attribute Longlist aligns with the DIN DKE SPEC 99100 and serves as a detailed reference for economic operators, outlining both mandatory and recommended data points. These attributes cover critical aspects such as battery identification, performance, material composition, and environmental impact, supporting the EU’s goals of circularity and carbon neutrality. The table below categorizes each attribute by number, name, data type (including units where applicable), whether it is static or dynamic, its mandatory or recommended status, and associated product attribute keys for technical implementation.

The attributes are structured as follows:

  • Number: Sequential identifier for each attribute.
  • Data Attribute: Name and description of the battery-related data field.
  • Data Type [Unit]: Specifies the format and measurement unit where applicable.
  • Static (S)/Dynamic (D): Indicates whether the attribute is a fixed property (S) or varies over time (D).
  • Mandatory (M)/Recommendation (R): Defines whether the attribute is required (M) or optional but recommended (R).
  • Circulor Keys: Identifies relevant keys that would be used when sending data to Circulor and setting up the Battery Passport.
