[0002] With the development and utilization of new energy and other clean energy in my country, as well as the promotion of energy conservation and emission reduction goals, some new demands have been put forward for the power sector and related units. For example, there are some contradictions between our country's electricity demand and power supply plan. For example, the electricity consumption during the day is usually significantly higher than that at night, but the power supply capacity of the power generator is usually fixed. In addition, the capacity of some special new energy sources, such as wind power, wave power generation and solar power generation, is usually volatile. Therefore, in order to meet my country's electricity demand, save electricity, and achieve the technical effect of energy conservation and emission reduction, people have begun to focus on energy storage equipment, hoping that the energy storage equipment can play the role of peak-filling and provide a solid foundation for my country's stable power supply.

[0009] However, in the prior art, the operation and management of the lithium battery energy storage power station still have the following defects:

[0010] 1. In existing energy storage power stations, lithium batteries are usually used as energy storage units. Although lithium batteries have high energy storage density, they produce hydrogen during chemical reactions when storing electricity. Therefore, if the shell of the lithium battery leaks or the diaphragm between the positive and negative electrodes is damaged, resulting in a short circuit, it is easy to cause fire and other risks.

[0011] In the present invention, by detecting combustible gas in the energy storage power station, when the concentration of the combustible gas is higher than a certain value, it is determined that there is a major leakage problem and there may be a risk of loss of control. The charging and discharging operations are disconnected in time and transferred to a safe treatment area to ensure safety.

[0012] 2. Existing energy storage power stations usually include a large number of battery cells. When storing energy, the batteries usually need to maintain a reasonable temperature and release heat when discharging. Therefore, heating the batteries alone requires energy consumption, which is not in line with the energy-saving and environmental protection role of new energy, nor is it reasonable to waste heat energy.

[0013] 3. In the existing technology, energy storage batteries are usually part of the working part of the power station, but these batteries are often in one space, which makes it difficult for heat to dissipate quickly, which easily leads to heat concentration. The other part needs to be electrically heated to maintain battery activity, which obviously leads to waste and heat management problems.

[0014] In response to the above technical issues, there is an urgent need to provide a system and method for fully monitoring and dynamically managing lithium battery energy storage power stations to address these issues. However, to date, there is no effective solution to the above technical difficulties in the existing technology. Summary of the Invention

At the same time, other lithium battery cells are started to charge or discharge, and abnormal information has been sent to the central integrated monitoring platform. The abnormal information is displayed on the central integrated monitoring platform so that staff can perform maintenance or inspection and deal with possible fire risks. At the same time, an alarm is issued through the reminder and alarm module to remind potential fire alarms.

[0025] Preferably, the video sensor module acquires video image data of the lithium battery module array and sends it to the central integrated monitoring platform, which analyzes the video image. When a fire alarm or potential fire alarm is detected in the video image, the position of the lithium battery pack unit is located in time.
