[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 through 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, causing a short circuit, it is easy to cause risks such as fire.

[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 large 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 battery usually needs to maintain a reasonable temperature and releases heat when discharging. Therefore, heating the battery alone requires energy consumption, which is not in line with the energy-saving and environmental protection function of new energy, nor is it reasonable to waste heat energy.

[0013] 3. In the prior art, energy storage batteries are usually part of the working part of a 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, while the other part needs to be electrically heated to maintain battery activity, which obviously leads to waste and heat management problems.
