Dukosi DK-NFLNK™ Evaluation Platform

The Dukosi DK-NFLNK™ Evaluation Platform is designed to enable battery pack developers and BMS designers to evaluate the advantages of Dukosi technology and discover its ease of integration into existing and future battery designs. DK-NFLNK is an intra-battery communication solution that upgrades modular battery architectures based on multi-channel AFEs to a more reliable and safer design with improved scalability and flexibility.

The DK-NFLNK Evaluation Platform supports technology evaluation and initial proof-of-concept development across a growing range of BMS host processors and AFE devices.

Ensuring Customer Success

If you are interested in evaluating DK-NFLNK as part of your current or next-generation battery design, please get in touch:

DK8503 Node

• One Node per module
• Single-chip communication device
• AFE-adaptable, enabling integration with a wide range of cell monitoring solutions
• Static and dynamic data storage available for regulatory requirements (EU Battery Passport)

DK8203 System Hub

• Directly connected to BMS Host processor via SPI (BMU)
• BMU adaptable, enabling integration with a wide range of BMS suppliers
• Independent communication with all DK8503 Nodes (star network)
• System Hub ensures each Node operates synchronously

Communications

• Custom near field connectivity using single bus antenna
• Proprietary communication protocol based on Dukosi C-SynQ®
• Designed from the ground-up for safety-critical applications in large, multi-node battery systems
• Deterministic communication with synchronized data transfer between System Hub and Nodes

Compared with far field wireless BMS solutions, Dukosi near field RF communication operates at very low power, generating minimal environmental noise and signal reflections, resulting in wired-like performance. This reduces interference risk and removes the need for repeated RF analysis or redesign following battery pack design changes, such as modifications to busbars, cell layouts, cooling systems, or thermal barriers.

The use of a simple single-bus antenna enables greater flexibility in mechanical design, and improves reliability compared with wired solutions and daisy-chained far field wireless solutions. The Dukosi star network configuration ensures that an error in one Node is immediately identified, and does not affect communication between other Nodes and the BMS host processor.

Regulatory-ready Design

In-chip data storage is available for module-level retention of both static and dynamic data, including sourcing and manufacturing information, material usage, and in-field operational and environmental usage. This capability supports global regulatory requirements (e.g., Battery Passport), asset tracking and supply chain security, a digital twin data source, operational streamlining for maintenance and remanufacturing, and circular economy enablement.

Easily Adaptable: One Battery to Many

Once implemented, the same BMS host processor and DK8203 System Hub can be reused across multiple battery pack designs. A common DK-NFLNK library and API supports all configurations while maintaining consistent RF performance.

This common architecture also enables straightforward migration from DK-NFLNK to the Dukosi Cell Monitoring System (DKCMS™). This provides battery designers with increased flexibility, scalability, manufacturing efficiency, operational performance, safety, reliability, and lifecycle sustainabilit
