The battery management system architecture is a sophisticated electronic system designed to monitor, manage, and protect batteries. It acts as a vigilant overseer, constantly assessing essential battery parameters like voltage, current, and temperature to enhance battery performance and guarantee safety.
The main objectives of a BMS include: The BMS continuously tracks parameters such as cell voltage, battery temperature, battery capacity, and current flow. This data is critical for evaluating the state of charge and ensuring optimal battery performance.
The main functions include collecting voltage, current, and temperature parameters of the cell and battery pack, state-of-charge estimation, charge-discharge process management, balancing management, heat management, data communication, and safety management. The battery management system mainly consists of hardware design and software design.
There are two primary types of battery management systems based on their design and architecture: Features a single control unit managing the entire battery pack. Simplifies data collection and control but may face scalability challenges for larger systems. Employs a modular architecture where smaller BMS units manage groups of battery cells.
Centralized battery management system architecture involves integrating all BMS functions into a single unit, typically located in a centralized control room. This approach offers a streamlined and straightforward design, where all components and functionalities are consolidated into a cohesive system. Advantages:
Modular battery management system architecture involves dividing BMS functions into separate modules or sub-systems, each serving a specific purpose. These modules can be standardized and easily integrated into various battery systems, allowing for customization and flexibility. Advantages:
