For front and back, in the present embodiment, they represent two opposite directions, and which one is front and which one is back can not be limited. Of course, the directions of front and back are perpendicular to the directions of above and below.

[0029] The technical solution provided in the application integrates the battery module, the control system 130 and the energy storage converter 120 in one cabinet 110, and improves the integration of the liquid-cooled energy storage integrated cabinet 100 and reduces the floor area by reasonably distributing the positions of the battery module, the control system 130, the energy storage converter 120, the battery liquid cooler 140 and the energy storage converter liquid cooler 150. In detail, first, the internal space of the cabinet 110 is divided into a battery compartment 114 and an electrical compartment 115, the battery compartment 114 is located above the electrical compartment 115, which provides a position partition for subsequent battery modules and other devices, and the battery compartment 114 is arranged above the electrical compartment 115, considering that the battery module has a large volume, being located above is more conducive to the placement of the battery module. Then, the control system 130 is arranged between the energy storage converter 120 and the battery module, so that the control system 130 can be electrically connected to the energy storage converter 120 and the battery module with shorter lines, reducing the wiring distance, reasonably utilizing the space between the energy storage converter 120 and the battery module, and reducing space waste.

By locating the battery liquid cooler 140 in front of the battery module, the battery liquid cooler 140 is as close as possible to the battery module that needs to be cooled, improving the cooling effect and shortening the cooling pipeline. Similarly, the energy storage and conversion liquid cooler 150 is located behind the energy storage and conversion device 120, which is also to make the energy storage and conversion liquid cooler 150 as close as possible to the energy storage and conversion device 120, shorten the cooling pipeline, and then play a better cooling effect. Moreover, the battery liquid cooler 140, the battery module, the energy storage and conversion device 120, and the energy storage and conversion liquid cooler 150 are placed close to each other, which is conducive to improving the compactness of the structure and improving the space utilization rate in the cabinet 110. In addition, because the energy storage and conversion liquid cooler 150 is located directly below the battery module, the energy storage and conversion liquid cooler 150 can radiate the heat to the battery module while cooling the energy storage and conversion device 120, further improving the cooling effect of the battery module. Similarly, the battery liquid cooler 140 can also cool the energy storage and conversion device 120 to a certain extent.
