[0054] Figure 1 A energy storage system is shown, including a battery 130 and an energy storage container, and the battery 130 is arranged in a battery compartment 115.

[0055] Figures 2 to 7Shows an energy storage container according to the present utility model. The energy storage container includes a box body 100 and a battery rack 120. The battery rack 120 is disposed inside the box body 100 and cooperates with the box body 100 to form at least two battery compartments 115 adapted to accommodate batteries 130. The battery rack 120 includes support rods 121, mounting beams 122, and a limiting assembly. The support rods 121 extend along the height direction D2 of the energy storage container. The upper end of the support rod 121 is connected to the top of the box body 100, and the lower end of the support rod 121 is connected to the bottom of the box body 100. The mounting beam 122 is connected to the support rod 121 and extends along the width direction D3 of the energy storage container. The mounting beam 122 is adapted to support the battery 130. The limiting assembly is disposed on the mounting beam 122 and is adapted to limit the battery 130 located on the mounting beam 122.

[0056] For the energy storage container according to the present utility model, the battery rack 120 cooperates with the internal space of the box body 100 to form the battery compartment 115 adapted to accommodate the battery 130, without interference from other structures, and has a high space utilization rate. The battery rack 120 limits the battery 130 on the mounting beam 122 through the limiting assembly, with a stable structure, and the connection between the support rod 121 and the box body 100 can strengthen the structural strength of the box body 100.

[0057] Optionally, referring to Figure 2 and Figure 3 , the energy storage container includes seven battery racks 120. The seven battery racks 120 are arranged at intervals along the length direction D1 of the energy storage container, so as to form six battery compartments 115 arranged along the length direction D1 with the box body 100. In addition, along the length direction D1, the battery rack 120 at one end of the battery rack 120 queue is disposed on the inner wall of one end face of the box body 100, and the battery rack 120 at the other end of the battery rack 120 queue is spaced apart from the inner wall of the other end face of the box body 100, thus forming a control compartment 116. The control compartment 116 is adapted to accommodate the electric control equipment and the cooling equipment, so as to control and cool and dissipate heat from the battery 130.

[0058] Further, referring to Figure 3 , the control compartment 116 includes an electrical compartment 117 and a liquid cooling compartment 118. The electrical compartment 117 is located above the liquid cooling compartment 118. The electrical compartment 117 is adapted to accommodate the control equipment to control the battery 130. The liquid cooling compartment 118 is adapted to accommodate the cooling equipment to cool and dissipate heat from the battery 130.

[0059] Referring to Figure 1, eight batteries 130 are arranged in each battery compartment 115. Among them, four batteries 130 form a cluster. Therefore, there are two clusters of batteries 130 in each battery compartment 115. The maximum capacity of the batteries 130 in the entire energy storage system can reach 5.0 MWh. The external dimensions of the box body 100 are the same as those of the existing 20HC standard container (an international sea freight container). Compared with the energy storage container composed of eight batteries 130 in a cluster (which can only accommodate ten clusters of batteries 130 with a battery capacity of 3.44 MWh), the space utilization rate inside the box body 100 is improved.

[0060] Refer to Figure 1 , a high-voltage box 140 is correspondingly arranged in each battery compartment 115, which is used to control, protect, and monitor the two clusters of batteries 130 in the battery compartment 115.

The box body 100 includes a box door 111 suitable for closing the opening 101 and a side plate 106 located on the other side of the box body 100. In other words, the box body 100 has a single-sided opening 101, which facilitates the installation and maintenance of the batteries 130 and other equipment by the staff from one side of the box body 100.

[0062] Optionally, refer to Figure 2 and Figure 5 , the box body 100 includes three groups of double-opening box doors 111. Each group of double-opening box doors 111 includes two box doors 111. The six box doors 111 in the three groups of double-opening box doors 111 are arranged in one-to-one correspondence with the six battery compartments 115, so that each battery compartment 115 can be independently opened and closed.

[0063] As one of the alternative solutions, the box body 100 can also include six single-opening box doors 111, and the six box doors 111 are arranged in one-to-one correspondence with the six battery compartments 115, so that each battery compartment 115 can be independently opened and closed.

[0064] Combined with Figure 5 shown, a box door 111 is also arranged outside the control compartment 116 corresponding to the box body 100. The box door 111 can be selected as a mesh panel 150, which is convenient for the heat dissipation of the control equipment and the liquid cooling equipment.

[0065] It can be understood that the solutions adopting other forms of box doors 111 should also be within the protection scope of the present utility model.
