Figure 2: Through its contactless architecture, DKCMS offers cell-level insight without increasing system complexity
Overcoming cell-level monitoring constraints Dukosi has been working on a solution to address these limitations. It developed a “smart cells” architecture, called the Dukosi Cell Monitoring System (DKCMS), based on an individual cell monitoring IC and a novel near-field communication bus. It is suitable for high-power battery packs that can contain hundreds or even thousands of cells. Te architecture brings intelligence to
each cell through its own monitoring IC – the so-called DK8102 Cell Monitor. Tis is is a chip-on-cell technology that captures the cell’s individual voltage, temperature and operational data. Each DK8102 is powered directly by the
cell it measures. With very low quiescent current and flexible power modes, cells can self-monitor potentially for years, without degrading their performance or lifespan. Temperature stability is equally critical.
Each sensor is individually calibrated across a wide temperature range during production, and the devices have been qualified to AEC, IEC, ISO and ASPICE quality and safety standards,
Far-field wireless approaches may reduce wiring,
volume, weight and potential
points of failure, but often struggle with data latency, signal interference and reliability, especially in dense, high-voltage environments
for safety and reliability. Tis ensures consistent, predictable behaviour even as components age. For data communication from cell to hub, the DKCMS uses a proprietary
near-field communication protocol (C-SynQ). A single, low-profile antenna bus removes the need for complex, heavy wire harnesses to network the cells. It runs above each cell’s near-field antenna, providing kilovolts of electrical isolation, with very high EMI immunity and very low emissions. Te system hub then aggregates and delivers the information to the BMS host with deterministic latency. C-SynQ was designed from the ground
up for large scale cell-level monitoring. It captures real-time data from each cell synchronously and at low latency. It also allows packs of variable sizes to be configured without redesigning the communications layer, giving battery manufacturers greater flexibility. The entire system captures accurate,
synchronous measurements of voltage, temperature and usage for every cell simultaneously, and stores a lifetime record of that data directly on the cell’s chip.
