No, the lithium battery protection circuit board isn’t identical to the lithium batteries BMS. BMS and lithium battery protection boards are both lithium battery protection umbrellas. But the difference between them is:
- Composition: The lithium battery protection board consists of IC, MOS tubes, resistors, and capacitors, belonging to the hardware protection, which is an important part of the lithium battery. The battery management system can be edited with its own battery management software, relatively more intelligent, equivalent to the brain of the lithium battery, and plays the role of management and control.
- Application: Li-ion battery protection board plays an important role in 3C lithium batteries and power batteries, while the battery management system is mainly used in power batteries.
In contrast to the lithium battery protection board, the battery management system offers greater ease of use and enhanced convenience. However, its performance is easy to be unstable in low temperatures.
