In the era of 5G and mobile Internet, with the rapid development of information and intelligent technology, the construction scale of data centers is getting larger and larger, and the number is also increasing，The importance and security of the battery, which is used to ensure the reliable operation of the equipment in the computer room, has attracted more and more attention。
Batteries in a data center are usually connected in series as battery groups. After the same battery group is used normally for a period of time, the voltage difference between each battery becomes larger，The voltage consistency of battery packs deteriorates gradually. If no effective measures are taken, the difference will become larger, resulting in reduced capacity of the whole battery pack or even scrapped。
1.Architecture design of online monitoring system for storage batteries in data center:
The battery monitoring system consists of a main control module, a current module, and a single battery module. The main control module can monitor important parameters of a single battery online. The main control module is connected to the background server through a serial port or network port to realize remote centralized management，Receives, processes, stores, and displays real-time data of all monitored batteries in the data center equipment room, and provides statistical analysis of important parameters and alarms, and user management functions。
2. System safety design
2.1 High stability: The company has been engaged in battery online monitoring research and development and production since 2008. It has a long time of battery monitoring product research and development experience. After more than 10 years of market tests, it has a number of technical patents。
2.2 High safety: the equipment uses good flame-retardant components and materials; The system can be completely independent of the monitored equipment and normal operation，The system will not cause interference to the UPS system and the working loop. The sampling line is not directly connected with the battery under test, and the ohm resistor is connected in the middle, which completely eliminates the danger of battery and human electric shock damage caused by the module failure。
2.3 High anti-interference ability: We have designed a multistage filtering circuit inside the module, and embedded a high-precision adaptive identification algorithm in the software. The products have been tested in detail in the UPS system of large brands, and the performance is stable。
When the monitored battery parameters exceed the safe range, the system automatically sends an alarm. Maintenance personnel can respond to the alarm in a timely manner to isolate or replace the outdated or damaged battery. This ensures that the battery sets work in good condition and prevents the backup power system from breaking down after a power failure, improving the security and reliability of the data center equipment room。
