[0041] Please refer to Figure 1. An embodiment of the present application provides an energy storage container, including a first cabin 100, a second cabin 200 and an electrical connection assembly 400. The first cabin 100 has a battery storage chamber 110 and a main controller storage chamber 120, and the battery storage chamber 110 is connected to the main controller storage chamber 120; the second cabin 200 is assembled with the first cabin 100 and detachably connected, and the second cabin 200 has an electrical component storage chamber 210 and a thermal management component storage chamber 220, and both the electrical component storage chamber 210 and the thermal management component storage chamber 220 are connected to the main controller storage chamber 120. The first cabin 100 has a first docking surface 130, and the second cabin 200 has a second docking surface 230 corresponding to the first docking surface 130; the electrical connection assembly 400 is penetrated through the first docking surface 130 and the second docking surface 230.

[0042] In the above energy storage container, the battery storage chamber 110 in the first cabin 100 is used to store the battery module 310, and the main controller storage chamber 120 is used to store the main controller 320. The battery storage chamber 110 is connected to the main controller storage chamber 120 to realize the electrical connection between the battery module 310 and the main controller 320. The electrical component storage chamber 210 in the second cabin 200 is used to store the electrical components, and the thermal management component storage chamber 220 is used to store the thermal management components. The first cabin 100 and the second cabin 200 are detachably connected. When the second cabin 200 needs to be connected When it reaches the first cabin 100, the first docking surface 130 and the second docking surface 230 are docked, and the electrical connection component 400 is passed through the first docking surface 130 and the second docking surface 230 to achieve electrical connection between the electrical component and the main controller 320 and between the thermal management component and the main controller 320; compared with the traditional technology, the above-mentioned energy storage container, the electrical component and the thermal management component are arranged in the second cabin 200, so that the first cabin 100 has a larger storage space for storing more battery modules 310, thereby improving the energy density of the energy storage container.

[0043] Specifically, referring to Figures 1 to 8, the shape of the first cabin 100 is roughly a rectangular parallelepiped, and the shape of the battery module 310 is also roughly a rectangular parallelepiped that matches the first cabin 100, so that a larger number of battery modules 310 can be stored, thereby improving the energy density of the energy storage container; the shape of the second cabin 200 is also roughly a rectangular parallelepiped that matches the first cabin 100, so that the overall structure of the energy storage container is more compact.

[0044] Specifically, please refer to Figure 8, there are multiple battery modules 310 in the battery storage chamber 110, and the multiple battery modules 310 are electrically connected to the main controller 320 in the main controller storage chamber 120, which can not only realize the series or parallel connection between the multiple battery modules 310, but also receive the electrical signals sent by the battery modules 310.

[0045] Specifically, the thermal management component in the thermal management component cavity includes at least one of a temperature monitoring component, a heat sink and a heater. The temperature monitoring component is used to be electrically connected to the main controller 320. The main controller 320 transmits an electrical signal about the current temperature of the battery module 310 to the temperature monitoring component. When the temperature monitoring component detects that the temperature of the battery module 310 in the first cabin 100 is abnormal, the heat sink or the heater operates and cools or heats the battery module 310 to ensure the safety and stability of battery charging and discharging.

[0046] Specifically, at least one of an electrical control component and a busbar component is provided in the electrical component storage cavity 210. The electrical control component transmits an electrical signal to the main controller 320. The main controller 320 controls the battery module 310 in the battery storage cavity 110 to adjust the charging and discharging power of the battery module 310. The busbar component can converge the current released by the battery module 310 to facilitate the subsequent current output.

[0047] Furthermore, in the above embodiment, when the electrical components need to be changed, there is no need to re-certify the electrical components, thereby reducing certification risks and costs.

[0048] As a supplementary explanation, the first cabin 100 and the second cabin 200 are detachably connected. When the energy storage container needs to be transported, the second cabin 200 can be disassembled and only the first cabin 100 with a standard size can be transported; when the second cabin 200 needs to be installed to the first cabin 100, the first docking surface 130 and the second docking surface 230 are docked. At this time, the electrical connection component 400 provided on the second docking surface 230 is passed through the first docking surface 130. In this way, the main controller 320 in the main controller storage cavity 120 can more conveniently realize electrical connection with the electrical components and the thermal management components.

[0049] Furthermore, by inserting the electrical connection assembly 400 into the first docking surface 130 and the second docking surface 230 , a certain fixing and supporting effect can be provided to the second cabin 200 , so that the connection between the second cabin 200 and the first cabin 100 is more secure.

[0050] As an explanation, in the conventional technology, in order to facilitate the transportation of energy storage containers, it is usually necessary to standardize the size of the energy storage containers. Since the storage space in the energy storage container with standardized size is fixed, and the electrical components and thermal management components need to be arranged in the energy storage container, the space for storing the battery module 310 in the energy storage container is small, which results in a low energy density of the energy storage container. In this embodiment, the electrical components and thermal management components are arranged in the second cabin 200, so the first cabin 100 has a larger storage space for storing more battery modules 310. 0, thereby improving the energy density of the energy storage container; in the above embodiment, the first cabin 100 is set as a cabin with a standardized size, so that the first cabin 100 can be quickly loaded and unloaded with different transportation tools, and can also be efficiently transferred and transported by different transportation tools, so as to achieve the effect of simplifying the transportation process and improving the transportation efficiency. When the energy storage container needs to be loaded, unloaded or transported, the second cabin 200 is disassembled from the first cabin 100, so that the on-site loading and unloading tools or transportation tools can more efficiently load, unload or transport the first cabin 100 with a standard size.
