In recent years, with the needs of the development of science and technology, the application of the battery in the UPS power supply is also very extensive, and the battery application at the same time, but also brought a series of problems, so it is very important to improve the safety and reliability of the battery operation, how to prevent the battery failure?

In the entire UPS power system, the battery is the device that determines the backup time of the UPS power supply, but the size of the battery capacity is reflected by the ampere-hour (AH) indicator, which means that the discharge time is carried out according to the specified current. The same voltage battery, large ampere-hours of large capacity; The same ampere-hours of the Viada battery, high voltage capacity is large, usually the voltage and ampere-hours together to indicate the capacity of the battery.

The ordinary backup UPS power supply generally has a built-in 4AH or 7AH battery, which is often said that the standard machine, the capacity of the battery is fixed, then the power supply time is determined by the size of the UPS load. In addition, the UPS power supply also has a long-term model with a large capacity battery, and the user can determine how much capacity of the battery is equipped according to the backup time that needs to be achieved. The battery is an important part of the UPS power supply, occupies a large proportion of value, and its quality is directly related to the normal use of UPS, so you should carefully choose a genuine battery with quality assurance.

The battery pack is composed of a certain number of single batteries in series. The failure of one single battery will lead to the failure and damage of the whole battery pack. Therefore, it is necessary to control the discharge process of the battery, especially the discharge process, and carry out online real-time monitoring of the charging and discharging voltage, current, and battery pole temperature of each single battery during the charging and discharging process of the battery pack. It is important to find out damaged or degraded batteries in time to extend the service life of the batteries and improve the reliability of the DC power supply system. Therefore, it is very important to ensure the good operation of each battery and fault prevention.

Weida battery online monitoring device is Baoding Yuxin Electric applied the avant-garde network communication and battery detection technology to achieve real-time inspection of the battery pack, which can realize the automatic detection of the single voltage, internal resistance, pole temperature of each single battery and the group voltage and charge and discharge current of the whole battery at a regular time. And according to the set parameters to the battery fault alarm in time.

The measurement data can be displayed in real time, or sent to the background database for storage, analysis and processing, and display the characteristic curve and bar chart of the battery. It can find the backward single battery in time, analyze the actual trend of the battery, grasp the operating status of the battery pack in real time, and ensure the reliable and trouble-free operation of the backup power system. The online monitoring of multiple battery sets is realized, which greatly reduces the system cost and provides economic and technical guarantee for customers to realize online monitoring of battery sets.
