MHP, AWS Launch New EV Battery Digital Twin Standard

MHP, a Porsche subsidiary and digitalization consultancy, has initiated and led the development of a new industry specification—DIN SAE SPEC 91487:2025-08—in partnership with Amazon Web Services (AWS) and a third collaborator. The standard defines terminology, characteristics, and a framework for digital twins of electric vehicle (EV) batteries. Developed over two and a half years via the Publicly Available Specification (PAS) process, it aims to unify global implementation across R&D and cloud-based platforms.

The DIN SPEC establishes a shared vocabulary and structure for categorizing battery digital twins, enabling consistent development and communication among global stakeholders. The framework does not impose algorithmic or application-specific constraints, allowing for broad adoption across OEMs, software vendors, and infrastructure providers. It is expected to streamline the deployment of digital twin solutions in cloud-based services and facilitate technical alignment between research teams and enterprise users.

MHP served as the working group leader and project initiator. AWS contributed a predefined reference architecture based on its Level 4 digital twin maturity model, which supports real-time battery monitoring through live vehicle data, fleet analytics, and AI. The specification was formulated collaboratively among all partners in the joint working group, ensuring balanced representation and input from multiple domains of expertise.

“It all started with the development of a digital twin at an automotive manufacturer. There was a lack of fundamental standardization. With the appropriate competence and expertise, projects of this size can now also be successfully implemented,” said Dr. Markus Schütten, Senior Manager at MHP.

Christian Stapel, Partner at MHP, added, “With the DIN SPEC, MHP has once again confirmed its expertise in the field of digital twins and its ability to set up standards on the scale of DIN. Based on this experience, MHP also offers itself as a reliable consulting partner in the development of further standards in various areas.”

The new standard enables organizations to more easily implement and reference digital twin solutions in internal workflows and external documentation. DIN SAE SPEC 91487 also supports classification and legal referencing of digital twin implementations in contracts, tenders, and regulatory filings. The inclusion of SAE International as a co-publisher ensures accessibility for North American companies and paves the way for future global alignment. Ultimately, the DIN SPEC is expected to evolve into a formal ISO standard to promote worldwide interoperability in EV battery digital twin technologies.
