Overview of BMS protection boardFirst, the concept of lithium-ion battery protection board can be understood as a simplified design of BMS, which completely through the hardware scheme to achieve over-voltage, under-voltage, over-current and other protection functions, does not require software control ; there are only simple resistance capacitance, MOS and control IC on the board. Today x27s goal is to understand its hardware solution step by step. 

 

According to the classification of management architecture, there are three main types of BMS products : centralized BMS, distributed BMS and semi-centralized BMS. Due to the high replicability of the distributed management architecture, it can be applied to a variety of different vehicle battery packs. Passive equalization management is widely used due to its low cost, low complexity and low failure rate. However, active equalization management has high management efficiency, large equalization current and low energy dissipation. With the gradual overcoming of thermal risk and circuit complexity, BMS gradually transits to active equalization management. In addition, integration, generalization and intelligence are also the future development trend of BMS technology. According to the classification of management architecture, there are three main types of BMS products : centralized BMS, distributed BMS and semi-centralized BMS.

For example, the design and manufacture of BMS PCBA for electric vehicles is a highly complex and technology-intensive process. High-performance and high-reliability BMS PCB board can be achieved by comprehensively considering design, material selection, manufacturing process, testing and quality control. With the continuous advancement of electric vehicle technology, the design and manufacture of BMS PCBA will also face more new challenges and opportunities.
