Dukosi Opens Sampling of DK-NFLNK Contactless Battery Communication Link
The solution uses a single bus antenna to replace traditional wiring between analog front-ends and the battery management system.
Dukosi has made its DK-NFLNK contactless communication solution available for sampling by key customers. The technology is designed to eliminate traditional wiring and connectors in battery packs built on conventional multi-channel analog front-end (AFE) designs by using a single bus antenna.
What Happened
The DK-NFLNK solution consists of two chips: the DK8503 Node and the DK8203 System Hub, along with the Dukosi API and a proprietary near-field protocol based on the company’s C-SynQ technology. Each DK8503 Node connects to an AFE over a standard SPI interface, with the product page specifying one Node per AFE. The system provides synchronous, module-level measurements from the AFEs to the BMS host, passing data through the bus antenna and the DK8203 System Hub, which connects to the host over SPI. Dukosi states that the contactless network uses a star topology and provides inherent electrical isolation. The chips are AEC-Q100 certified and designed to be ASIL C compliant.
Why It Matters
For battery designers, DK-NFLNK offers an upgrade path from wired or far-field wireless BMS designs without requiring changes to the underlying battery architecture, as the solution is AFE-agnostic. The company notes that the same BMS host processor and System Hub can be reused across multiple battery pack designs, and a common library and API support all configurations, which minimizes software development and maintenance efforts. The near-field implementation is intended to minimize RF power levels and simplify mechanical integration. Intended applications extend beyond electric vehicles to include industrial and marine uses, robotics, battery energy storage systems (BESS) for utility and grid-scale projects, telecom infrastructure, and AI data centers. Joseph Notaro, President of Dukosi, stated that DK-NFLNK and the Dukosi Cell Monitoring System (DKCMS) share a common communication foundation, providing a migration path to full DKCMS-enabled Smart Cell battery designs.
The Bottom Line
Dukosi’s DK-NFLNK is now available for sampling, offering a contactless alternative to wired battery monitoring systems. The evaluation kit includes hardware components and software tools to support technology evaluation and initial proof-of-concept development on various BMS host processors and AFE devices.
