A BMS may monitor the state of the battery as represented by various items, such as: • : total voltage, voltages of individual cells, or voltage of periodic taps • : average temperature, coolant intake temperature, coolant output temperature, or temperatures of individual cells.
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.
Although the battery management system has relatively complete circuit functions, there is still a lack of systematic measurement and research in the estimation of the battery status, the effective utilization of battery performance, the charging method of group batteries, and the thermal management of batteries.
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 most critical issue for battery control and management is how to obtain the battery states such as SOC, SOE, SOP, SOT, SOH, and RUL. However, these states cannot be measured directly by sensors and can only be obtained by estimating measurable parameters such as voltage, current, and temperature.
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:
