Intelligent battery capacity discharge test system

System composition

The figure is a simplified diagram of the entire battery discharge test system.

1. Portable

Connect the positive and negative wires of the DC input part of the capacity tester to the positive and negative poles of the battery, and the AC part of the wires to the corresponding AC power supply. The monitor fixes the wiring clips on each battery in order. Then connect the communication port of the monitor to the computer and the discharge meter respectively to form the structure shown in the figure. This is the basic connection method of the portable. Then, by operating the computer, the system can be made to work, and the relevant data can be recorded, and the computer can derive the remaining capacity of each battery.

2. Fixed

The fixed connection method can be the same as the portable connection method, and the PC calculates the result of the remaining capacity of the battery. However, the fixed type can be separated from the computer, and the monitor calculates the remaining capacity of the battery and sends it back to the required platform. This reduces the equipment and can be fixed on any position or standard size rack as needed.

Superior features

This system can only use the monitoring software to organize and analyze the data collected by the monitor when the capacity tester tests the battery capacity, forming an intuitive and clear data chart, built-in database, and automatically recording various data and information during each test

Rapid discharge predicts the remaining capacity of the battery

Using the rapid discharge measurement operation of this system, the capacity of the tested battery pack can be quickly predicted within a short period of 7 to 30 minutes at a discharge rate of 0.15C. And the remaining capacity of each single cell can be predicted with an accuracy of more than 80%. Using this function, a large number of batteries can be quickly measured, greatly improving the efficiency of measurement and facilitating a quick understanding of the battery status. The system has 24 pairs of probes that can be directly connected to the two ends of each single battery. During the system discharge test process, the status of each single battery can be intuitively reflected using the monitoring software, and the lagging battery can be discovered in time, providing convenience for the maintenance of the battery pack.

Deep discharge for more accurate measurement and maintenance of battery remaining capacity

The deep discharge measurement operation of this system can be used to perform deep discharge measurement or maintenance on the tested battery pack at a standard discharge rate of 0.1C. During the discharge measurement process, there is no need for manual supervision. As long as the termination discharge conditions are pre-set: termination discharge voltage, discharge time, or discharge by hours, as long as any of the three conditions is met, the system will automatically stop discharging and automatically record data, thus avoiding a large number of manual operations during the system discharge process.

Scope of application

This system has been widely used in the communication equipment operation and maintenance departments and communication construction departments. Our company is also using this system for battery maintenance, mainly for:

project acceptance of new battery packs

After the communication equipment installation project is completed, it is necessary to accept the performance of the battery pack itself and the quality of the installation. After testing with this system, a set of test data and charts are obtained, which intuitively reflects the working performance of the battery pack, and can find defects in the battery pack and installation as early as possible to achieve the purpose of acceptance. Due to the high accuracy of the system test, it has also been welcomed by many battery manufacturers.

Perform daily maintenance according to the requirements of the specifications According to

the requirements of the communication equipment maintenance specifications, the battery pack needs to be charged and discharged regularly to ensure the working performance and service life of the battery pack. Using this system for capacity discharge measurement can accurately find out the lagging battery, and through the charge and discharge cycle, the capacity of the lagging battery can be effectively restored to meet the needs of daily maintenance. Through daily measurements, the archives of the battery pack can be established. Once a power outage occurs, a more accurate estimate of the battery's continuous power supply capacity can be made to ensure that communication is not interrupted.

Measuring and identifying battery packs

When the battery reaches a certain service life, the system is used to measure and identify the battery pack to determine whether the battery pack has reached the level of scrapping, which provides a reliable basis for the management department to make decisions.
