　　What is the BMS 402030 battery protection board? What are the functions of the BMS battery management system? BMS management system is also called battery protection board. As 402030 battery products are more and more widely used, more and more accidents are caused by the use of lithium batteries. In order to ensure the safety of product use, 402030 battery protection board BMS has become a key component in 402030 battery applications. part. This system can not only improve the safety of the product, but also extend the service life of the product. It is a standard configuration for the production and testing of 402030 battery protection boards.

　　What is the BMS 402030 battery protection board?

　　BMS battery protection board, as the name suggests, the 402030 battery protection board is an integrated circuit board that protects rechargeable (generally lithium batteries). The main purpose of the battery management system (BMS) is to improve battery utilization, prevent battery overcharge and overdischarge, extend battery life, and monitor battery status. As the battery management system develops, other functions will be added.

　　The main function of the power 402030 battery protection board is to provide a 402030 battery management system for energy supply for motors, energy storage equipment and other systems. The 402030 battery protection board is a charge and discharge protection for series 402030 battery packs; its function: effectively improves the charging effect in series charging mode, and simultaneously detects overvoltage, undervoltage, overcurrent, short circuit, etc. of each single cell in the battery pack. Over-temperature status, protect and extend battery life.

　　At present, single power lithium batteries have basically met the conditions for promotion and application, but the existing group technology, group application technology and equipment level are not yet mature. In other words, single power lithium batteries basically solve the problems of safety and lifespan. The key to promoting the development of power lithium batteries is battery group technology and BMS technology.

　　BMS battery management system functions

　　1. Monitoring function

　　The monitoring function is the most basic function of the battery management system, which provides reliable data for the management function. Monitoring content includes battery terminal voltage, current, temperature and other parameters.

　　2. Protection function

　　Protection functions include overcharge protection, over-discharge protection, short circuit protection, reverse connection protection, overload protection, temperature protection, etc.

　　3.Measuring function

　　The metering function is to dynamically report the SOC status of the battery during use. Theoretically speaking, there is a certain corresponding relationship between the voltage and capacity of the battery. By comparing the SOC data during use with the theoretical SOC data, the battery can be judged life span.

　　4.Control function

　　Through the interface and communication protocol, the battery status is connected to the external connection to realize the function of automatic control or remote control.

　　The battery management system BMS mainly covers the following functions:

　　1) Battery working status monitoring: mainly refers to the real-time monitoring or calculation of a series of battery-related parameters such as battery voltage, temperature, working current, battery power, etc. during the working process of the battery, and judging the current battery status based on these parameters. To perform corresponding operations to prevent overcharging or over-discharging of the battery.

　　2) Battery charging and discharging management: During the charging or discharging process of the battery, the charging or discharging of the battery is managed according to the environmental status, battery status and other related parameters, and the optimal charging or discharging curve of the battery (such as charging current, charging current, etc.) is set. Upper limit voltage value, discharge lower limit voltage value, etc.)

　　3) Balance between single cells: that is, balanced charging of single cells so that each battery in the battery pack reaches a balanced and consistent state. The equalizer is the core component of the battery management system, but the current domestic technology in this area is not yet mature.

　　Summary: The above is an introduction to the functions of the BMS battery management system. The BMS battery management system is widely used. With the many electronic devices that require battery supply, the use of rechargeable batteries has increased dramatically. To ensure that batteries are charged correctly and optimize their service life, battery management or fuel gauge systems grow in parallel. The BMS 402030 battery management system is now complete.
