Edinburgh startup Dukosi designs and markets a new battery management technology that uses wireless communications protocols to transmit data on the health of a battery’s individual cells across the battery pack.
The BMS chipset uses near field communication technology with a single antenna, to monitor and process data directly on the individual cells of the battery and wirelessly communicate this data to the central BMS. The chip, mounted on a cell, simplifies battery pack design to save weight and enable higher cell density.
Dukosi will use GF’s Auto Pro Solution to ensure that quality and reliability of the 55nm design meets the demands of ACQ100 for the automotive industry. The chip includes current, voltage and temperature sensor alongside an ARM Cortex-M3 controller core and its own digital signal processing core running a custom machine learning algorithm.
The company expect samples of production silicon back in the next few months, with full production in 2022, Nat Edington, CEO of Dukosi told eeNews Power.
“Battery management is essential for the safe and efficient operation of batteries” said Edington. “The market requires a BMS that can meet the space and reliability demands of their applications. To date, battery management has been done with heavy and bulky wires, linking all cells to a central BMS. By replacing individual wires with one simple antenna, more accurate measurement and processing of the data at source, on every cell, batteries become inherently safer, simpler and smarter.”
The wireless chip enables lighter, less complex high voltage batteries, with more granular data reported and processed. It does this by providing a wireless sensor hub for each cell, eliminating all the wires, pins, connectors, and printed circuit boards of modular battery systems. A single antenna cable, paired with NFC technology, communicates from hundreds of cells to one central BMS per battery for more flexible battery pack architectures. The technology may also be used for new and second-use cells in energy storage systems, says Edington.
“GlobalFoundries is an ideal partner and has a proven track record of established quality, which will support the chips’ 20-year lifetime requirements, in order to perform reliably through first and second life applications,” he added.
“GlobalFoundries is excited to partner with Dukosi to create innovative solutions to revolutionize battery management systems for electric vehicles,” said Kamal Khouri, vice president of automotive at GF “This partnership is a great example of how companies such as Dukosi use GF’s feature-rich technology to create disruptive solutions, in this case, for the automotive industry and the evolution of the electric vehicle.”
