Dukosi’s contactless cell monitoring solution has been designed for safety critical, next generation battery systems. It is extremely robust, scalable, flexible, higher performing, and more reliable than traditional battery architectures.
DKCMS consists of the DK8102 Cell Monitor chip, DK8202 System Hub chip, and the Dukosi Library API. A Cell Monitor mounted directly onto each cell provides accurate monitoring of key operating parameters such as voltage and temperature, along with necessary cell balancing functionality and diagnostics. The System Hub manages the bidirectional data transfer between all of the Cell Monitors and the BMS Host using Dukosi’s proprietary C-SynQ communication protocol, using near field RF via a single bus antenna. C-SynQ provides highly secure and extremely robust and reliable communication with predictable latency, while synchronising all Cell Monitor measurements, improving the accuracy of SoX calculations, and thus, battery pack performance.
Each DK8102 Cell Monitor has an on-chip die temperature sensor and inputs for two external thermistors. By capturing the temperature of every cell, DKCMS improves the safety and reliability of batteries because other architectures typically only install one sensor every several cells in a module. Monitoring the temperature of every cell can precisely detect any cell experiencing an overtemperature event during operation.
Compared to wired architectures, DKCMS removes the need for complex wiring harnesses and connectors, reducing component count by 10x, reducing materials cost, and improving reliability twofold.
DKCMS allows batteries to be more compact, lighter, and scalable by one cell at a time, enabling designs to better meet capacity or space requirements. Alternative far field wireless architectures require redesign and revalidating when scaled or reshaped, but DKCMS just works! It’s flexibility and scalability are unparalleled.
DKCMS with C-SynQ is ideal for a wide range of battery-powered applications such as electric vehicles, battery energy storage systems, marine applications, industrial transportation including ground support equipment for airport terminals and ramp operations, and even eVTOLs.
Dukosi offers development tools to evaluate and accelerate the development of DKCMS-based battery systems. The DK8x02 Evaluation Kit (EVK) is a powerful evaluation and development tool used by battery developers and BMS designers to discover the unique advantages DKCMS, and begin to build their next-generation batteries. From unboxing to establishing a cell network using Dukosi’s intuitive Windows-based software environment (GUI) can be achieved in as little as 15 minutes. For energy storage developers, a 54-cell reference design is available to streamline the creation of rack modules. Dukosi provides comprehensive support to partners throughout the development of their next-generation battery designs and accelerate their time to market.
