- the container can be placed under another container, the lower corner pieces of the other container bearing on the upper corner pieces of the container.
- Such a container does not give complete satisfaction when it is placed outside. Since the roof of the container is flat, rainwater falling on the roof is likely to stagnate above the container. This stagnation occurs particularly in the center of the container, especially in the areas furthest from the side edges of the roof.
- the stagnation of rainwater can in certain cases cause premature wear of the container, in particular by promoting oxidation, or even by creating holes which communicate with the interior volume containing the battery modules.

- the roof panel 100 is supported by the bearing surfaces 64 defined on the longitudinal members 60 and the crosspieces 62.
- each through opening 102 passes vertically through the roof panel 100.
- the roof panel 100 here comprises two parallel through openings 102, located on either side of the axis A-A', projected in a plane horizontal.

- each roof panel 100, and each deflagration plate 104 attached to the roof panel 100 is located under the upper plane P defined by the upper surfaces 72 of the upper corner pieces 70.
- the deflagration plates 104 have a surface upper located vertically under the upper point 86 of the inclined sections 82A to 82D.
- the rainwater which falls at the central water evacuation region 80 is naturally evacuated towards the side edges of the container 12 thanks to the inclined sides 82A, 82B, and away from the center of the roof 40 by the inclined sides 82C, 82D.
- the container 12 therefore has a longer lifespan and increased reliability of the battery modules 16 it contains, since they are not exposed to humidity. In addition, it presents an improved exterior aesthetic appearance, even if subjected to bad weather.
- the central water evacuation region 80 being located under the plane P defined by the upper surfaces 72 of the upper corner pieces 70, it does not interfere with the normal transport of the container 12.
- the container 12 can be transported under other containers of a stack of containers, receiving, on its upper corner pieces 70, lower corner pieces of another container. This allows it to be loaded onto ships, thus reducing transport costs.
- the longitudinal inclined sections 82A, 82B have, in projection in a horizontal plane, an area greater than that of the transverse inclined sections 82C, 82D.
- the area of the longitudinal inclined sections 82A, 82B is notably greater than more than 200% of the area of the transverse inclined sections 82C, 82D.
- the longitudinal sections 82A, 82B delimit between them a horizontal upper edge 120, extending parallel to the axis A-A' and defining a plurality of upper points 86 of the central water evacuation region 80.
- the upper edge 120 extends between the edges 88, 90 of each panel 82A, 82B.
- the upper edge 120 thus defined is located in the plane P, or under the plane P defined by the upper surfaces 72 of the upper corner pieces 70.
- the longitudinal inclined sections 82A, 82B thus have a trapezoid-shaped contour, while the transverse longitudinal sections have a triangular contour.
- the roof 40 does not have a non-inclined region 84.
- the water evacuation region 80 extends over the entire length and width of the roof 40.
- the area occupied by the transverse inclined sections 82C, 82D is preferably less than 10% of the area occupied by the longitudinal inclined sections 82A, 82B.
- the entire water evacuation region 80 is located in the plane P or under the plane P.
- the through openings 102 for overpressure evacuation are provided directly in the inclined sections 82A, 82B and the deflagration plates 104 are attached to the inclined sections 82A, 82B on the periphery of the through openings 102, as described previously.
- a layer of thermal insulation for example a fibrous layer made of rock wool, is placed under the roof 40, in particular, in the volume delimited between the support surface 64, and the inclined sections 82A to 82D.
- This variant promotes thermal insulation of the battery modules 16, particularly when the temperature increases outside the energy storage system 10.
