[0002] The present application relates to the technical field of energy storage battery, in particular to a battery pack mounting guide rail and an energy storage container. BACKGROUND

[0003] The size of a single Pack of a battery energy storage system is getting larger and larger, especially the length dimension, which leads to the size of the battery pack mounting guide rail also being made longer. The battery pack mounting guide rails in the industry mostly adopt L-shaped guide rails. SUMMARY

[0004] However, after the L-shaped guide rail is made longer, there are problems of unstable fixation, difficult processing and welding, and weight increase. Moreover, the battery pack mounting guide rail mostly adopts the method of coating the surface of the fixing screw on the battery pack mounting guide rail with conductive paint to realize grounding, which is unreliable.

[0005] The present application provides a battery pack mounting guide rail applied to an energy storage container. The battery pack mounting guide rail comprises a support part, a connecting part connected with the support part and forming an L-shaped structure, and a first limiting part protruding from the connecting part and arranged opposite to the support part. The support part, the connecting part, and the first limiting part jointly define a limiting cavity, which is configured to realize limiting fixation of a battery pack.

[0006] The present application also provides an energy storage container, which comprises at least two oppositely arranged battery pack mounting guide rails as described above, and a battery pack comprising a shell, the outer side of the opposite sides of the shell being provided with a fixing part, and the opposite two fixing parts being arranged in the limiting cavities of the opposite two battery pack mounting guide rails, respectively. ADVANTAGEOUS EFFECTS

[0007] The battery pack mounting guide rail provided by the present application can realize effective fixation of the battery pack by arranging the first limiting part on the connecting part and forming the limiting cavity, and cooperating with the fixing part on the battery pack, thereby improving the fixation effect.

[0008] The energy storage container provided by the present application can improve the installation stability of the battery pack on the battery pack mounting guide rail by arranging the fixing part on the outer side of the shell of the battery pack and arranging the fixing part in the limiting cavity of the battery pack mounting guide rail.
