DKCMS Core

Dukosi Cell Monitoring System

Overview

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 DKCMS Library 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 controller (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.
