This innovative modular communication link, DK-NFLNK™, offers a simple upgrade path from traditional wired and long-range wireless BMS architectures to a more reliable battery solution. This technology enables synchronized module-level measurements to be sent to the host BMS using Dukosi's proprietary contactless communication protocol, based on C-SynQ®.
The DK-NFLNK demonstrator shown represents a standard 12-cell battery module configuration, typical of 400-800V battery packs used in electric vehicles (xEVs) and battery energy storage systems (BESS). The design utilizes the DK8503 EVK Node board with an integrated antenna, which connects to an industry-available analog feed-in-feed (AFE) multi-channel monitoring device.
The DK8503 node transmits module data in a synchronized and secure manner using Dukosi’s proprietary near-field communication protocol, via a simple bus antenna to the host BMS system, using a DK8203 System Hub device.
Joseph Notaro, Chief Revenue Officer at Dukosi, stated: “The DK-NFLNK proof of concept demonstrates how our highly secure and reliable communication solution can easily upgrade existing modular battery architectures to a more scalable and robust design without requiring any modification to the battery architecture. By leveraging Dukosi’s proven C-SynQ communication protocol, this solution eliminates complex wiring and fault-prone connectors between modules and the BMS processor, while ensuring data integrity and synchronization. DK-NFLNK is also AFE-adaptable, enabling seamless integration with a wide range of cell monitoring solutions.”
