Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1, the utility model discloses an embodiment's energy storage platform includes energy storage module 1, two end plates 2 and two curb plates 3, as shown in fig. 2, energy storage module 1 includes two battery modules 11, and two end plates 2 set up at energy storage module 1's both ends relatively, and two curb plates 3 set up in energy storage module 1's both sides relatively, and the one end of curb plate 3 is connected with the side buckle of an end plate 2, and the other end of curb plate 3 is connected with the side buckle of another end plate 2.

The energy storage module 1 of the present embodiment includes two battery modules 11, in other embodiments, the number of the battery modules 11 is more than two, and the number of the battery modules 11 is selected according to actual needs. The battery module 11 in the energy storage module 1 in the energy storage platform of this embodiment need not alone to retrain, and energy storage module 1 is whole to retrain through two end plates 2 and two curb plates 3, and the assembly work load is little. Because the both ends of curb plate 3 are connected with 2 buckles of an end plate respectively, the assembly degree of difficulty is low and improved energy storage platform's assembly efficiency, has reduced the demand to frock tool to the cost is effectively reduced.

As shown in fig. 2, the end plate 2 further includes a first main body plate 21 and two first side plates 22, the two first side plates 22 are oppositely disposed on two sides of the first main body plate 21, the first main body plate 21 is attached to the end surface of the energy storage module 1, the first side plate 22 is attached to the side surface of the energy storage module 1, and the side plate 3 is connected to the first side plate 22 in a snap-fit manner. The first sideboard 22 of end plate 2 is through the side laminating with energy storage module 1, makes energy storage module 1 can carry on spacingly to end plate 2, prevents that end plate 2 from taking place the displacement. The side plate 3 and the first side plate 22 are both located at the side of the energy storage module 1, and a snap connection between the two is convenient.

Furthermore, the side plate 3 includes a second main body plate 31 and two second side plates 32, the two second side plates 32 are oppositely disposed on two sides of the second main body plate 31, two ends of the second main body plate 31 are attached to the first side plate 22, and the second side plates 32 are attached to the first main body plate 21.
