The battery is the heart of every electric vehicle, but its production is resource-intensive and its traceability complex. To enable sustainability and transparency throughout the entire lifecycle, digital solutions are needed.
A digital battery twin creates a real-time digital representation of the physical battery and makes information about origin, composition, lifespan, and CO₂ footprint available. This forms the foundation for the digital battery passport, which will be mandatory in the EU from 2027.
What does the new standard achieve?
Until now, there was no unified framework for developing digital battery twins. DIN SAE SPEC 91487 “Terms, definitions and characteristics for the use of Digital Twins of electric vehicle batteries” now provides a standard for the first time.
The DIN SPEC, developed jointly by the companies MHP, AWS, and Accenture together with SAE International:
- defines key terms and characteristics,
- supports battery categorization,
- describes a maturity model ranging from static basic data to self-learning optimization models.
What’s next?
DIN SAE SPEC 91487 facilitates the development of battery twins, creates a common language, and makes applications internationally comparable. With over 128,000 members from aerospace, automotive, commercial vehicles, and regulation, SAE International brings international reach to the development of the standard.
This participation opens up the opportunity for DIN SAE SPEC 91487 to potentially evolve into an ISO standard – thereby creating the foundation for a globally unified battery passport.
