The PoC represents a complete solution incorporating 16 cells, a standard configuration in battery modules used in industrial equipment, battery energy storage systems (BESS), and electric vehicle (xEV) applications. The design utilizes Dukosi's chip-on-cell technology with proprietary C-SynQ® communications, along with microcontrollers (MCUs) and secure components from ST, demonstrating the potential of lifetime authenticated data from cell to cloud and a tamper-proof Battery Passport to build trust in the supply chain, improve repairability, and extend battery lifecycles through safe reuse and recycling.
Joseph Notaro, Chief Revenue Officer of Dukosi, stated:
“The collaboration with ST has allowed us to demonstrate the multiple advantages of Dukosi’s chip-on-cell technology when combined with STSAFE™ hardware encryption technology, enabling the safe replacement of damaged individual cells to improve sustainability, safety and maintainability, while preserving the complete history of each cell throughout its lifetime and the integrity of the Battery Passport through cell-to-cloud data encryption and authentication.
This turnkey safety solution will allow OEMs and Tier 1 suppliers to leverage this benchmark platform to accelerate the development of safer, smarter, more reliable batteries that are compliant with European battery regulations, driving 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, head of the Secure Edge & IoT eSIM business unit at STMicroelectronics, added:
“The integration of Dukosi’s chip-on-cell technology with STSAFE secure elements offers a significant opportunity for Battery Passport applications, enabling a secure solution throughout the entire product lifecycle. The STSAFE-A120 makes this possible with advanced protection and security by design, providing authentication, confidentiality, and platform integrity services for the battery management system.”
About the Safe BMS Demonstrator with Battery Passport:
Ready for the EU Battery Passport, compliant with DIN DKE SPEC 99100.
DKCMS-based battery architecture with STSAFE-A120 that improves safety, maintainability, and complete traceability throughout the cell's lifespan (cell passport).
Award-winning, regulation-ready architecture that enhances the performance, safety, reliability, and serviceability of next-generation batteries.
Turnkey BMS solution with cell-to-cloud encryption, secure authentication, and lifecycle data protection.
In the live demonstration, one cell includes a user-controllable internal heater to generate variable temperature conditions. A variable voltage is also simulated across all cells to reproduce charge and discharge cycles and surge events.
These events form part of the dynamic data in the Battery Passport and, along with static data, are stored in the non-volatile memory of the modules. The unique identifier 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.
When a cell is removed and replaced, the system detects a discrepancy in the new cell's unique identifier within the network, triggering a tamper alert and restricting access to system data and operations. An authorized maintenance procedure can be simulated through the GUI, allowing authorized personnel to properly register and replace the cell.
This demonstration highlights the flexibility, repairability, security, and robustness of the DKCMS cell-to-cloud, Battery Passport-ready BMS solution.
