Battery charging and discharging tester

Product Overview

Uninterrupted power supply is a fundamental guarantee in all operating equipment and network systems with continuously improving levels of informatization and automation. Whether it is an uninterrupted power supply system for AC or DC, the battery plays an extremely important role as a backup power source in the system. Normally, the battery is in a float charging standby state. In the event of AC power failure or other accident situations, the battery becomes the energy supplier for the load.

We know that in addition to the normal service life cycle of batteries, early failure of some batteries may occur due to quality issues such as material, structure, process defects, and improper use. In order to verify the standby time and actual capacity of the battery pack and ensure the normal operation of the system, according to the maintenance regulations of the power system, it is necessary to conduct regular or timely capacity verification discharge tests on the battery pack to detect individual failed or nearly failed individual cells early and replace them to ensure the effectiveness of the entire battery pack; Or evaluate the expected lifespan of the entire battery pack.

After years of research and development, our company has successfully developed a series of intelligent and accurate battery pack capacity testers using its proprietary technology. This tester can serve as a discharge load when the battery is online, and achieve constant current discharge of the set value by continuously regulating the discharge current. When discharging, if the terminal voltage of the storage group or the individual cell voltage drops to the set lower limit value, or the set discharge time is reached, or the set discharge capacity is reached, the instrument will automatically stop discharging

Record valuable and continuous real-time data during the discharge process.

This testing system uses wireless relay access for voltage monitoring information of individual batteries, which is simple, safe, and accurate. This instrument has a very user-friendly human-machine interface. Not only can various settings and data queries be completed under the prompts of the menu, but the discharge process data is also stored in the device's memory. It can be read and transferred through the data interface, and analyzed by the software of the upper computer to generate the required curves and reports.

Characteristics of charge and discharge instrument without monitoring function

By using PTC ceramic resistors, the phenomenon of red heating is avoided, making the entire discharge process safer.

The internal controller adopts dual CPU collaborative work to maximize the safety, reliability, and accuracy of testing. When one of the CPUs fails, the other CPU will issue an alarm and execute a shutdown program.

The discharge part adopts full electrical isolation technology, which means that this instrument can still work freely in strong electromagnetic interference and strong power interference environments.

2G ultra large capacity internal data storage space, external USB drive can support up to 32GB.

It has functions such as verification capacity testing, pause discharge, parallel load testing, online compensation discharge, etc., and can adapt to various complex on-site situations.

There is a USB interface that can transfer the data from the discharge process to a USB drive and import it into a PC. PC data management software can analyze the process of battery discharge and generate corresponding data reports. Make data transfer more convenient.

Adopting intelligent microcontroller ARM control and 7-inch touch LCD display in both Chinese and English, the menu operation is simple and clear.

Automatic protection function, set the discharge duration to, discharge capacity to, battery pack voltage below the set low protection voltage, abnormal load connection, etc., automatically stop discharging and alarm, and automatically record the shutdown mode.

Multiple discharge termination conditions, including battery pack termination voltage, discharge capacity, and discharge time, ensure the safety of discharge testing.

It can perform online compensation discharge, and by connecting an external current clamp sensor, it can perform discharge testing on the battery in online operation, greatly facilitating the testing work. This feature is particularly suitable for situations where there is only a single backup battery.

Multiple charging termination conditions can be set, including charging time up, charging capacity up, high total charging voltage, high charging cell voltage, and charging current exceeding the range.

Activation function, can set up to 10 automatic cycles for discharging and charging.

0.05% monomer voltage acquisition accuracy, 1mV resolution.

There are three types of wireless/wired communication methods. 1. The wireless acquisition box has wireless/RS485 communication function with the discharge host, which can monitor the voltage status of each unit in real time through the discharge instrument. 2. The PC end upper computer software and wireless monitoring module have wireless/RS485 communication function, which can directly monitor the voltage status of a single unit wirelessly without the need to connect to a discharge meter. 3. After the upper computer software on the PC end is connected to the discharge tester through an RS485 communication line, remote control of discharge can be performed.

The wireless collection box can monitor each battery and achieve complete monitoring of the discharge process of the battery pack.

The equipment installation, debugging, and maintenance are simple, and isolation technology is used before and after each acquisition module, ensuring high safety and reliability.
