IIOT System for Monitoring and Controlling Battery Management System in Redox Flow Batteries

The Industrial Internet of Things (IIoT) plays an important role in enhancing the efficiency and management of various systems, including Battery Management Systems (BMS). The aim of this thesis performs an IIoT application for Battery Management Systems which offer monitoring, control, safety, and optimization of Redox Flow Battery performance. The BMS is implemented using a Programmable Logic Controller (PLC) to control and monitor the battery and its performance. Generally, PLCs are built to withstand harsh industrial environments. For instance, temperature variations, electrical noise, and vibration. These features make PLCs more suitable for BMS applications. The PLC is connected to various sensors that measure critical parameters of the redox flow battery, such as temperature, pressure, level, and flow sensor to control the battery inside safety limits. Furthermore, PLC communicates with I-IOT devices using industrial communication protocols such as Profinet, Modbus-TCP/IP, and OPC-UA to achieve more complex control in the battery. The design and challenges of the BMS are explained in this thesis with the selection of components (sensors, PLC type, and PLC I/O modules) and I-IOT devices. One of the important properties of the system is the recording of the selected parameters into a database for the development and improvement of the algorithms. In this thesis couple of approaches are introduced according to some limitations and needs of the applications. The PLC in the BMS is integrated with the Human Machine Interface (HMI) system and eHMI to provide a comprehensive view of the entire battery system. The product preference and the design of the HMI systems are also introduced in this thesis.
