Online monitoring scheme for internal resistance of 2VEG200 Yinshan battery in communication room

Online monitoring scheme for internal resistance of 2VEG200 Yinshan battery in communication room

1、 Background of the plan:

With the continuous development of the communication industry, the number of communication center computer rooms is also increasing. As an important power supply equipment for various computer rooms, the importance of batteries is self-evident. From the current usage situation of batteries, it is common to see that the battery capacity decreases too quickly, the service life is short, and some major safety accidents often occur. Although there are differences in the quality and performance of batteries on the market, the current quality of batteries from major manufacturers can meet user requirements. Therefore, the quality factor of the battery accounts for a small proportion of the decrease in battery capacity and shortened service life.

From factors such as the structure, performance, and usage process of the battery, as well as feedback from users, it can be seen that the main reason for the rapid decrease in battery capacity and shortened service life of the communication center computer room should be related to the inadequate maintenance and monitoring of the base station operating environment.

2、 User challenges:

a. Unable to obtain real-time information on important parameters such as battery voltage, internal resistance, and temperature.

b. Unable to predict the battery capacity SOC and health status SOH in the computer room.

c. Unable to detect outdated batteries in the UPS backup battery pack, warning of unexpected power outage accidents.

d. Manual detection accuracy has errors, high costs, and is prone to accidents such as battery short circuiting.

e. When a battery failure occurs, there is no alarm notification, and users cannot immediately know and take corresponding measures.

3、 Example of solution:

3.1 User Requirements and Equipment Conditions:

The person in charge of a communication center's computer room contacted us through the internet, hoping to collect online data on the voltage, internal resistance, temperature, and group voltage of individual batteries. At the same time, it is required to have a system backend for online real-time viewing of various battery states and data. When monitoring the internal resistance of a single battery or the surface temperature of the battery is too high, detailed alarm information should be promptly sent to relevant administrators and other functions.

Application scenario: Communication center computer room battery online monitoring

Products used: battery intelligent parameter sensor, RS485 communication module, battery inspection cloud monitoring terminal.

Customer battery model and quantity: A single set of 48 2V batteries, totaling 2 sets.

3.2. Solution:

According to user needs and equipment conditions, Junda Technology - WeChat online monitoring solution for battery internal resistance was selected. The front-end equipment is connected to the network, collecting data from the battery in the computer room and uploading it to the system backend, which is installed in the headquarters monitoring center. Users can directly view the real-time operating status of the battery through a web-based browser on the computer, display the health status of the battery in real-time in the form of charts, bar charts, and freely set alarm thresholds. At the same time, it supports anytime and anywhere viewing of the real-time operating status of the battery in the base station and receiving abnormal alarm information through mobile WeChat (no limit on the number of people).

3.4 Functional Features:

(1) Reduce the amount of battery maintenance work and maintenance costs for manual inspections.

(2) 24-hour real-time monitoring, actively monitoring the operation status of the battery pack at any time, achieving real-time monitoring of important parameters such as voltage, internal resistance, temperature, etc. of each battery in the battery pack.

(3) Estimate battery capacity SOC, health status SOH, judge scrapped and expired batteries, effectively extend battery service life, reduce battery replacement costs, and ensure environmental protection of batteries.

(4) You can synchronously view the running status of each group and battery in real-time online through WeChat and web computing.

(5) When a battery failure occurs, an alarm is issued as soon as possible, and users can view detailed faults through their mobile phone WeChat and keep historical records.

3.5. Scheme Configuration:

1. Battery inspection cloud monitoring terminal: (single can monitor 96 batteries)

Small size, light weight, low power consumption, small footprint, and easy installation. It can perform status monitoring and alarm functions on individual battery voltage, battery internal resistance, battery temperature and other parameters within the battery pack. At the same time, various statuses and data can be viewed in real-time online through two methods: mobile WeChat and computer WEB, supporting standard MODBUS and SNMP protocols, and providing communication protocol content for third-party platforms to collect.

2. Intelligent parameter sensor for battery: (one for each battery)

The intelligent parameter sensor of a battery is a module that measures the internal resistance of a single battery using a small direct current discharge method. It can also simultaneously measure the voltage, resistance, and pole temperature of a single battery, and can be cascaded for communication.

3. RS485 communication module:

It adopts an aluminum profile shell, with small size and light weight, and supports 485 interface level communication. It is mainly used for the conversion between 485 communication and SBUS communication. With the intelligent parameter sensor of the battery, it can upload the collected battery voltage, temperature, internal resistance, balanced charging state and other parameters to the upper computer or collection system through RS485 interface.
