Dukosi will be joining Innovatrix as one of our exhibitors at the upcoming DZOM EXPO taking place at the Donald E. Stephens Convention Centre in Chicago, IL, on December 3–4, 2024.
Dukosi is developing revolutionary technologies and solutions that dramatically improve the performance, safety, reliability, and cost-effectiveness of battery systems, while also enabling a sustainable and circular battery value chain. The company is first-to-market with its unique chip-on-cell technology, designed from the ground-up ready for next-generation batteries to power applications such as electric vehicles, stationary battery energy storage systems, and industrial transportation.
Dukosi Cell Monitoring System (DKCMS)
The Dukosi DK8102 Cell Monitor makes precise, synchronous, on-cell measurements of Voltage and Temperature. Each Cell Monitor uses Dukosi’s proprietary C-SynQ® communication protocol to send data to a Dukosi DK8202 System Hub using near field RF via a single bus antenna placed over the battery pack cells. The System Hub typically resides on the same PCB as the BMS host processor, and communicates using the DKCMS library. DKCMS has been architected expressly for high performance batteries. It is designed to be extremely robust, and power efficient.
DKCMS Core
The DKCMS Core enables a robust, contactless cell monitoring solution for high voltage battery packs in a variety of applications. The overall system consists of Cell Monitors, a System Hub, and the Dukosi API which runs on the BMS Host. The Cell Monitors make accurate, synchronous, on-cell measurements, process the data, and send it to the BMS main processor (Host) via the System Hub. Communication between the Cell Monitors and System Hub uses Dukosi’s proprietary C-SynQ® protocol via near-field RF using a single bus antenna.
DK8x02 Evaluation Kit
The DK8x02 Evaluation Kit (EVK) is a powerful evaluation and development tool used by battery developers and BMS designers to discover the unique advantages of the Dukosi Cell Monitoring System (DKCMS) and begin to build their next-generation batteries. Unboxing to establishing a cell network using intuitive Windows-based software environment (GUI) can be achieved in as little as 15 minutes.
The EVK includes:
- Cell Monitor board (apply one per cell: order as many as required)
- System Hub unit (just one is required to manage up to 216 Cell Monitor boards)
- All cables included: USB, SPI, balun and bus antenna, and coaxial cable
- Powerful, yet easy-to-use software GUI that offers a visually assistive digital-twin of the battery setup
- Comprehensive documentation and company support throughout the product development journey
Dukosi Cell Monitoring System (DKCMS) can deliver the performance and reliability gains needed for the next generation of batteries that will power industrial transportation and mobility applications. With each Dukosi Cell Monitor providing synchronized, highly accurate, detailed granular information of each cell’s behavior and lifetime status, DKCMS provides better insight into a battery pack’s long-term use. This gives industrial vehicle and robotics manufacturers more confidence to unlock greater utilization from each cell while ensuring longevity, slowing or reducing the drop in range over the life of the vehicle.
By eliminating the complex wiring harness, supplementary PCBs, connectors, module assemblies, and other associated components, DKCMS enables battery pack weight reduction and reliability improvements. This results in a simpler, streamlined battery design. The reduction in weight and improved data quality can enhance the range, while still meeting the same reliability and warranty standards.
Vehicle designers and OEMs can scale easily to address different markets with changes to battery capacities and chemistries without requiring full revalidation thanks to DKCMS. Forgoing the limitation of a modular architecture, they benefit from the flexibility of singular cell increments connected using reliable C-SynQ® communication from the Dukosi System Hub residing on the central BMS host.
Allowing every cell in the battery pack to be monitored 24/7, even when the main BMS host is in a low-power state, DKCMS provides immediate detection and alert to cell-level problems and enables earlier fault diagnosis, creating a safer, more reliable electric vehicle. This detection is at least 5 minutes earlier than battery packs without cell-level temperature measurement, which can be crucial to give more time for people to act in response to events such as temperatures outside safe zones. If necessary, the Dukosi solution can wake the host controller at any time, even if the vehicle is unattended during shipping or parked in a garage, for example.
DKCMS requires fewer components per battery pack, which in turn simplifies the manufacturing process and supply chain, reducing materials costs, and it can potentially enable a fully automated assembly line by eliminating time-consuming manual assembly line steps when installing wires, connectors, and pins.
By capturing and storing lifetime data on each cell, the DKCMS promotes a circular economy (reduce, reuse, recycle) throughout the battery value chain. When the Dukosi Cell Monitor is implemented at an early stage in cell manufacturing, the solution offers lifetime traceability and helps OEMs to show compliance with the latest regulations. In addition, the lifetime usage data, including any extreme excursion events, are stored, yielding further advantages such as better cell grading, residual value assessment, and safer and more cost-effective second life usage or recycling.
