Why use battery monitoring management system

With the development of the times, the use of secondary battery also has some disadvantages, such as less storage energy, short life, series and parallel use problems, use safety, battery power estimation difficulties and so on. The newly developed zco-420 series battery monitoring and management system of our company is mainly to improve the utilization rate of the battery, prevent overcharge and over discharge of the battery, extend the service life of the battery and monitor the state of the battery. With the development of battery management system, other functions are added.

 

 

Zco-420 series battery monitoring and management system is used for real-time online monitoring and management of the operating parameters of the battery’s single voltage, single internal resistance, current and ambient temperature. Avoid human interference caused by the use of hand-held equipment, and all tests are carried out automatically. Ensure that the battery is in the safest operating environment.

 

[real online measurement of internal resistance]

 

The internal resistance test process of zco-420 series battery monitoring and management system is completed automatically. There is no need to change the operating state of the battery pack. At the same time, in the process of internal resistance test, there is no need to discharge, which is a really safe internal resistance measurement method.

 

[modular structure design to meet various battery configurations]

 

Zco-420 series battery monitoring and management system adopts modular structure design. Each zco-420-s module can connect up to 128 batteries in series. It can satisfy various battery system configurations through different module combinations.

 

 

Internal resistance test method:

 

Relevant parameters of basic technical parameters of the module

 

Internal resistance test method alternating current method

 

Internal resistance test signal frequency 10-300hz regulation

 

Internal resistance test current signal amplitude 1a-10a (regulated according to battery capacity)

 

Internal resistance test cycle is controlled or set automatically according to the command

 

Control signal module bus

 

System composition:

 

Zco-420-s: battery monitoring and acquisition host, RS485 communication interface, supporting Modbus communication protocol;

 

Zcm-cp-e: Ethernet module, which converts data into Ethernet communication protocol and transmits it through Ethernet;

 

Zcm-cp-f: optical fiber module, which converts data into optical fiber protocol and transmits it through optical fiber;

 

Zcm-cp-g: GPRS module, the data is transmitted by SMS, and the alarm information is sent to the designated mobile phone at the first time.

 

 

It can be seen that zco-420 series battery monitoring and management system can accurately estimate the state of charge, reduce the damage to the battery, predict the state of charge of the energy storage battery at any time, and facilitate the operation of simple personnel, greatly reducing unnecessary work.
