Battery Management System (BMS) Architecture: A Technical
The architecture, as depicted in the diagram, illustrates a comprehensive approach to monitoring and controlling the battery system, incorporating overcurrent protection, cell
Data is sent to a BMS Master Controller, which aggregates and analyzes the information. Battery Management Unit (BMU): The Battery Management Unit (BMU) is a key component in a Battery Management System (BMS) responsible for monitoring and measuring critical parameters of the entire battery pack or its individual cells.
From real-time monitoring and cell balancing to thermal management and fault detection, a BMS plays a vital role in extending battery life and improving overall performance. As the demand for electric vehicles (EVs), energy storage systems (ESS), and renewable energy solutions grows, BMS technology will continue evolving.
BMSs are used in various applications, including Electric Vehicles (EVs), smartphones, renewable energy storage systems, and other devices powered by rechargeable batteries. The building unit of the battery system is called the battery cell. The battery cells are connected in series and in parallel to compose the battery module.
Based on the provided block diagram, we will walk through the essential components and functions of a typical BMS architecture used in EVs, referencing each major block from the image. Li-ion Cells (Battery Cells): The foundation of the system consists of lithium-ion cells that form the battery pack.
