Addressing the performance, safety, and sustainability of high-power battery systems, Dukosi’s DK-NFLNK contactless communication solution enables the development of safer, more reliable batteries based on traditional multi-channel analog-front-end (AFE) designs. DK-NFLNK, which is AFE-agnostic, offers an upgrade path from traditional wired or far-field wireless battery-management system (BMS) architectures to a highly scalable and robust battery communication solution without needing to change the battery architecture. 

DK-NFLNK eliminates traditional wiring and fault-prone connectors with a single bus antenna. It delivers synchronous, module-level measurements from the AFEs to the BMS host. Connection is made using Dukosi’s proprietary contactless communication protocol based on C-SynQ; it’s available for customer sampling and development of battery systems.

DK-NFLNK creates a contactless communication channel between the BMS Host processor and a multi-channel AFE, with the DK8503 Node connecting to the AFE via a standard SPI connection. It transfers data to and from each AFE and the BMS Host processor via Dukosi’s DK8203 System Hub through a single near-field bus antenna implementation, minimizing RF power levels and simplifying mechanical integration. 

With inherent electrical isolation through the contactless network, DK-NFLNK delivers wired-like performance in a reliable star network. The same BMS host processor and DK8203 System Hub can be reused across multiple battery-pack designs.

A common DK-NFLNK library and API support all configurations, minimizing software development and maintenance across the business, while maintaining consistent RF performance. DK8503 and DK8203 are AEC-Q100 certified and designed to be ASIL C compliant.
