Figure 1. A Simplified Diagram of the Building Blocks of a Battery Management System A battery management system can be comprised of many functional blocks including: cutoff FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real time clock (RTC), temperature monitors and a state machine.
This review deals with this important part of the battery-management system (BMS). A general block diagram of a BMS is shown in figure 1. The basic task of the power module (PM) is to charge the battery by converting electrical energy from the mains into electrical energy suitable to charge the battery (see figure 1).
The architecture, as depicted in the diagram, illustrates a comprehensive approach to monitoring and controlling the battery system, incorporating overcurrent protection, cell balancing, temperature sensing, and failsafe mechanisms.
In a distributed battery management system architecture, various BMS functions are distributed across multiple units or modules that are dispersed throughout the battery system. Each module is responsible for specific tasks and communicates with other modules and the central controller.
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:
