From 18 February 2027, any battery in electric vehicles, light means of transportation, and industrial applications above 2 kWh placed on the EU market will require a digital product passport (DPP).
As the regulatory and technical foundations for the Digital Product Passport (DPP) take shape, developers and organizations across Europe are preparing to implement their battery passport solutions. Translating regulations and upcoming DPP standards into reliable, interoperable systems requires not only a deep understanding of the requirements, but also practical ways to test whether those requirements are met in real-world scenarios.
To support this process, the project BatteryPass-Ready is developing a dedicated testing environment that enables developers and system providers to validate their implementations of both battery passports and DPP systems. Its design is the result of intensive work on the relevant requirements and an active dialogue with key stakeholders. This ensures that the testing environment does not reflect merely the regulatory framework but also the realities of implementation and system integration.
Two Complementary Testing Functions
The testing environment consists of two main components. The first allows users to validate individual battery passports against the schema of battery passport data defined within the project. A new data attribute list – building on the previous Battery Pass work and the DIN DKE SPEC 99100, and updated to reflect new regulatory and standarisation developments – will soon be published. The validation function function ensures that the data structure and content meet the expected format and criteria. In the coming months, we will introduce additional capabilities that expand validation to more complex aspects, to also include conditional checks and checks of other data related inconsistencies, that can’t be covered by a schema validation. While BatteryPass-Ready focuses on the validation of battery passport data, these functionalities can also become applicable to other product passports in the future, supporting broader testing and compliance across digital product categories.
The second component focuses on testing complete DPP system implementations. According to EU requirements, these systems must reliably support core operations such as creating, reading, and updating digital product passports, while maintaining secure communication and mutual trust between multiple actors in the ecosystem. Based on the BatteryPass-Ready user stories, the testing environment emulates this multi-actor setting, providing realistic interaction patterns between different system roles. Developers can assess how well their implementations handle these interactions and identify weaknesses early before their systems go live.
Building Confidence and Enabling Compliance
Ultimately, the testing environment aims to make compliance verification accessible, transparent, and repeatable. By providing a structured framework for evaluating interoperability, data integrity, and regulatory alignment, it helps organizations navigate complex requirements with greater confidence: Decision-makers gain a clearer understanding of whether their systems meet essential functional expectations, while technical teams receive actionable feedback to refine their implementations.
What’s next
By June 2026, the goal is to provide broader access to the testing environment, empowering stakeholders to test their implementations independently and benchmark their progress toward readiness for the forthcoming battery passport obligations. The platform will continue to evolve as new regulatory aspects emerge and as partners share insights from their testing experience.
As access expands, BatteryPass-Ready invites interested organizations to engage with the project, share their feedback, and explore how this testing environment can support their own development and compliance journeys. Ensuring functional, interoperable, and compliant DPP systems is a collective effort, and systematic testing is a crucial step on the way there.
