[0002] UPS batteries are used as backup power sources in case of power outages. They are widely used in power substations, communication rooms, and mobile base stations. The reliability and safety of UPS batteries are becoming increasingly important as the information society places higher and higher demands on power supply security and communication reliability in communication systems. Although UPS battery technology has been effectively improved, people are still troubled by the reliability issues of UPS batteries.

[0003] The current problem is that battery packs typically operate in series, and existing online battery monitoring systems are unable to monitor the cell voltage, group voltage, cell internal resistance, and internal temperature of a single battery pack. If a problem occurs with a single battery, the system must investigate each one individually, wasting staff time and effort and preventing rapid identification of the specific battery pack causing the problem. Therefore, a new technical solution has been proposed. Utility model content:

[0006] A UPS battery monitoring system includes multiple battery packs, each of which is electrically connected to a battery input port on a battery inspection unit. The battery inspection unit is used to collect data on single-cell voltage, group voltage, single-cell internal resistance, and internal battery temperature of the battery pack. The output end of the battery inspection unit and the input end of a switch are connected via an RS485 bus communication. The output end of the switch is connected to a monitoring server via a network. The monitoring server is connected to a PC client via a network. The monitoring server is connected to a signal receiver via a network. The signal receiver is electrically connected to a voice alarm and a display screen.

[0007] Preferably, the battery inspection unit includes a main control chip, a battery sensor, a temperature sensor and a data storage unit; wherein the main control chip is electrically connected to the battery sensor and the temperature sensor respectively, and the battery sensor and the temperature sensor are installed near the battery bracket.

[0008] Preferably, the voice alarm and display screen are installed next to the corresponding battery pack.

[0009] Preferably, the main control chip is an STM32 microprocessor.

[0010] The advantages of this utility model are: it can quickly issue fault alarms for individual battery packs, making them easy to find; at the same time, it can monitor the single-cell voltage, group voltage, single-cell internal resistance, and internal temperature of the battery pack in real time online, and promptly send alarm signals to the PC client and signal receiver for abnormal monitored data, reducing the cost of manual inspections by users, allowing management and maintenance personnel to promptly discover problems or potential hidden dangers and deal with them in a timely manner, thereby ensuring the reliability and safety of UPS system operation.
