Dukosi

Dukosi is a semiconductor company specializing in battery monitoring solutions designed to enhance the performance, safety, and lifespan of battery systems. The Edinburgh-based firm was founded in 2003 by Joel Sylvester, who currently serves as the Chief Technology Officer. Sylvester, the primary inventor of Dukosi's technology with 61 patents, previously worked as Head of Electronics at the UK Astronomy Technology Centre and has a background in systems engineering and mixed-signal integrated circuit design.

The company's core product is the Dukosi Cell Monitoring System (DKCMS), a chip-on-cell technology that embeds a monitor directly onto each cell within a battery pack. This system provides real-time, high-precision measurement of key parameters like voltage and temperature. A key feature is the proprietary C-SynQ® contactless communication protocol, which uses a single bus antenna to transmit data from each cell monitor to a central System Hub. This architecture significantly reduces the complex wiring harnesses found in traditional battery management systems (BMS), thereby improving reliability, simplifying design, and increasing scalability. The technology is chemistry-agnostic and applicable to battery packs of any size.

Another feature is the 'Cell Passport,' which stores lifetime data, including manufacturing details and operational events, on each cell's embedded memory. This facilitates traceability and helps determine a cell's health for second-life applications, supporting compliance with regulations like the EU Battery Passport. Dukosi primarily serves the electric vehicle (EV), industrial transportation, and stationary battery energy storage systems (BESS) markets. Its business model involves providing its hardware chipset and API to customers and partners for integration into their battery and BMS designs. As of September 2024, the DKCMS Core hardware has passed AEC-Q100 qualification and is ready for volume production.
