The PoC represents a complete solution incorporating 16 cells, a standard configuration for battery modules used in industrial equipment, energy storage, and xEV applications. The design utilizes Dukosi's chip-on-cell technology with proprietary C-SynQ® communications, combined with ST's MCU and Secure Element.
The demonstration showcases the potential for lifetime authenticated data from the cell to the cloud and a tamper-proof Battery Passport, contributing to increased supply chain trust, improved repairability, and extended battery lifecycles through safer reuse and recycling.
According to Joseph Notaro, Chief Revenue Officer of Dukosi:
“Our collaboration with ST has allowed us to demonstrate the numerous advantages of Dukosi’s chip-on-cell technology when combined with STSAFE™ hardware encryption technology. This enables the safe replacement of damaged individual cells to enhance sustainability, safety, and maintainability, while preserving each cell’s history throughout its lifespan and the integrity of the Battery Passport with encryption and authentication of data from the cell to the cloud.
This turnkey security solution will allow OEMs and Tier 1 suppliers to leverage the benchmark platform to accelerate the development of safer, smarter, and more reliable batteries that are compliant with the EU Battery Regulation and drive sustainable electrification. With a shared commitment to sustainability, innovation, and excellence, ST has been an ideal partner, both technically and strategically, to accelerate the adoption of our technologies and build a more sustainable and circular battery supply chain.”
Agostino Vanore, Secure Edge & IoT eSIM Business Unit Manager at STMicroelectronics, commented:
“Integrating Dukosi’s chip-on-cell technology with the STSAFE secure elements offers a significant opportunity for battery passport applications by enabling a secure solution throughout the entire product lifecycle. The STSAFE-A120 makes this possible through advanced protection and security by design, supporting authentication, confidentiality, and platform integrity for the battery management system.”
About the secure cell-to-cloud BMS demonstrator: Battery Passport-ready and
compatible with the EU Battery Passport – compliant with DIN DKE SPEC 99100.
DKCMS-based battery architecture with STSAFE-A120, enhancing safety, maintainability, and complete traceability throughout the cell's lifecycle (cell passport). This award-winning, regulation-ready battery architecture improves the performance, safety, reliability, and serviceability of next-generation battery systems for multiple electrified applications.
Key BMS solution with integrated cell-to-cloud encryption, secure authentication, and lifetime data protection.
In the live demonstration, one of the cells includes a user-controlled internal heater to generate variable temperature conditions. A variable voltage is also generated for all cells to simulate charge and discharge cycles and overvoltage events.
These events are part of the dynamic data in the Battery Passport and, along with some static data, are stored in the non-volatile memory of the cell monitors. The unique ID of each Dukosi Cell Monitor is stored in the STSAFE-A120 to ensure data encryption and validation.
The graphical user interface (GUI) includes sections dedicated to:
Battery Passport management,
data encryption, and
secure validation processes.
When an individual cell is removed and replaced, the system detects a discrepancy in the new cell's unique ID on the network, signaling a potential tampering anomaly and restricting access to other cell data and system operations.
An authorized maintenance procedure can be simulated via the GUI, where valid credentials allow authorized service personnel (PLIs) to register and replace the cell.
This demonstration highlights the flexibility, repairability, safety, and security of the Battery Passport-ready DKCMS and STSAFE solution, with secure cell-to-cloud battery management.
