The present embodiment provides an energy storage container, the structural layout of which is substantially the same as that of the energy storage container provided in embodiment 1, and is different in that, in this embodiment, as shown in fig. 7, when ten battery clusters 1 inside the energy storage container are arranged in a manner of being divided into two rows and five columns, each row of battery clusters 1 includes five battery clusters 1, the two rows of battery clusters 1 are oppositely arranged, and a maintenance channel 30 is provided between the two rows of battery clusters 1, and the side surfaces of the two rows of battery clusters 1, where the electrical wire bundles are arranged, face the maintenance channel 30, so that interference of the electrical wire bundles on the opposite battery clusters can be avoided.

Further, when the maintenance channel 30 is formed between the two rows of battery clusters 1, and the side surfaces of the battery clusters 1, on which the electric wire bundles are arranged, face the maintenance channel 30, both ends of the maintenance channel 30 extend to the side surfaces of the container body 20, and the box doors 21 are arranged at both ends of the side surfaces of the container body 20, corresponding to the maintenance channel 30, so that maintenance personnel can enter the maintenance channel 30 through the box doors 21 to repair and replace the electric wire bundles of the two rows of battery clusters 1.

While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and the scope of the utility model is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the principles and spirit of the utility model, but such changes and modifications fall within the scope of the utility model.
