Dukosi has introduced its DK-NFLNK contactless communication solution for customer sampling and battery-system development. The technology provides a way to modernize battery systems that use conventional multi-channel analog front ends (AFEs) by replacing wired connections between the AFE and BMS host with a contactless communication link. This removes the need for wiring and connectors while maintaining compatibility with existing battery architectures.
The AFE-independent DK-NFLNK platform comprises the DK8503 Node chip, DK8203 System Hub chip, Dukosi’s API, and a proprietary contactless protocol based on C-SynQ. The DK8503 interfaces with a standard AFE through SPI, while battery data is transferred to the BMS host processor through the DK8203 and a single bus antenna. Its near-field communication technology uses low RF power, helping simplify integration into battery-pack designs.
The contactless architecture also electrically isolates battery modules from the BMS host. Dukosi says the system delivers wired-like communication in a star-network configuration while supporting synchronized measurements at the module level. The DK8203 and BMS host processor can be reused across different battery-pack designs, while a shared software library and API can help reduce development and maintenance work.
Both the DK8503 and DK8203 are AEC-Q100 certified and designed to support ASIL C compliance, making them suitable for applications requiring high reliability and functional safety. Target markets include electric and hybrid vehicles, industrial and marine batteries, robotics, grid and utility energy storage, telecommunications infrastructure, and AI data-center power systems.
For developers, Dukosi offers a DK-NFLNK Evaluation Kit (EVK) with a graphical user interface. The kit includes the Node board, System Hub, optional resistor-divider board, USB and SPI connections, bus antenna, coaxial cables, Windows software, and documentation. It is designed to help engineers evaluate the technology and develop proof-of-concept systems using different BMS processors and AFE devices.
