NF21 intelligent battery discharge meter

Intelligent battery discharge monitor
This instrument is specially designed for the verification discharge experiment capacity test of the battery pack, the daily maintenance project acceptance of the battery pack, and other DC power supply load capacity tests. Using the latest wireless communication technology, the battery discharge process can be monitored in real time through machine monitoring software, and the discharge process of each battery can be monitored.
The power consumption part of this instrument uses a new type of ceramic resistor as the discharge load, which completely avoids the red hot phenomenon and is safe, reliable and pollution-free. The whole machine is controlled by a microprocessor, and the LCD displays a Chinese menu. It has a novel appearance design, is small in size, light in weight and easy to move. After various discharge parameters are set, the entire constant current discharge process is automatically completed. Completely intelligent. Make the entire discharge process safer.
The portable and intelligent professional design of this instrument series makes discharge testing simple and easy, greatly reducing the labor intensity of professional maintenance personnel, and also improving the scientific nature and intelligence of discharge testing.
Functional Features
The use of ceramic resistors avoids the phenomenon of red heat and makes the entire discharge process safer.
It has wireless communication function. The wireless collection box communicates with the discharge host and the host computer monitoring machine through wireless means. Simplified wiring, flexible and convenient.
The wireless collection box can monitor each battery to achieve complete monitoring of the battery pack's discharge process.
The equipment is easy to install, debug and maintain. Isolation technology is used before and after each acquisition module, which ensures high safety and reliability.
The equipped machine monitoring system can monitor the entire discharge process in real time and monitor the total voltage and discharge current. Analyze data such as the voltage of each single cell and generate corresponding data reports. Curves, graphic reports, etc. that intuitively reflect the performance of the battery pack, and can be printed and queried.
With an interface, the data of the discharge process can be stored in the disk and imported into the machine. Data management software can analyze the battery discharge process and generate corresponding data reports. Make data transfer more convenient.
Using an intelligent microcontroller to control the LCD display in Chinese and English. Menu operation is simple and clear.
Automatic protection function, set the discharge time to the discharge capacity to the battery pack voltage is lower than the set minimum protection voltage, if there is an abnormality in the load connection, etc., it will automatically stop the discharge and alarm, and automatically record the shutdown method.
Test/discharge termination conditions can be set, including single cell voltage, battery pack termination voltage, discharge current, and discharge time.
Battery pack capacity can be estimated by short-term discharge minutes.
It can record the discharge status of each battery during the test/discharge process, mainly the total capacity, total voltage, total current of the battery pack and the voltage changes of the single cell with the lowest voltage.
