The importance of using 18650 battery 2000mah phosphate battery pack management system

　　The importance of using 18650 battery 2000mah phosphate battery pack management system. In order to ensure the safety and reliability of using 18650 battery 2000mah phosphate battery packs, it is very necessary to develop and manufacture a management system for lithium battery packs. The lithium battery management system provides an interface for interacting with external systems, such as charging power supplies, switching devices, loads and Data display equipment.

　　The importance of using 18650 battery 2000mah phosphate battery pack management system

　　A 18650 battery 2000mah phosphate battery management system will transform a group of "dumb" cells into a smart lithium battery pack. The production process of 18650 battery 2000mah phosphate batteries is relatively complex. The consistency difference of single cells will be greater than that of sealed valve-regulated lead-acid batteries. This will cause the voltage of individual single cells to rise rapidly in the later stages of charging of the lithium battery pack. Excessive differences will seriously affect the battery life. In order to avoid the above phenomenon. It is necessary to use other power management systems to ensure the safety and reliability of the battery.

　　The battery management system is a core component of the protection and management of lithium battery packs. It not only ensures the safe and reliable use of the battery, but also gives full play to the performance of the battery and prolongs its service life. As a backup power for communications, the management system operates at high voltages. It acts as a bridge between DC power supply and battery. The requirements for the 18650 battery 2000mah phosphate battery pack management system must meet the requirements of the communication power supply system, so the safety management mode of the battery management system is crucial to the safety of the battery.

　　Due to the complex manufacturing process of 18650 battery 2000mah phosphate batteries and the relative activity of lithium ions, the voltage of individual cells in the lithium battery pack is inconsistent. Balanced charging of the single cells in the lithium battery pack so that the single cells in the battery pack reach a balanced and consistent state can effectively extend the service life of the battery pack and greatly improve the working efficiency of the lithium battery pack.

　　With the rapid expansion of the power battery and energy storage battery market, the demand for lithium battery management systems will also expand rapidly, and its growth rate will be the same as that of lithium batteries. At present, battery management systems at home and abroad have entered the practical application stage, but the research is not mature enough and the performance is not ideal enough. Since the early market demand has been opened, the development of battery management systems will follow the approach of "technical improvement" and "commercialization" going hand in hand.

　　As lithium battery packs are increasingly used in high-power equipment, such as electric vehicles, the requirements for battery management systems are getting higher and higher, and the functions of lithium-ion battery management systems are becoming more and more powerful.

　　It is generally believed that the 18650 battery 2000mah phosphate battery pack management system should have the following functions: detection of external parameters of the battery pack, judgment of battery status and estimation of remaining power, charge and discharge control of the battery pack, battery balance, and provision of communication with external devices. Function. At present, the detection technology of battery external parameters has become mature, and the current focus of research on lithium-ion battery management systems is the estimation of remaining battery power and the balance of lithium battery packs.

　　As a control unit that protects the safety of 18650 battery 2000mah phosphate battery packs and ensures reliable operation of the battery pack, the battery management system is particularly important for the future promotion of electric vehicles.
