Referring to fig. 1 to 9, the present invention provides a battery holder 130 and an energy storage container 100 having the battery holder 130. The energy storage container 100 includes a case 10 formed with a receiving cavity, the case 10 having a top side beam 111 and a bottom frame 112, and a battery compartment 13 provided in the case 10. Referring to fig. 2, a battery holder 130 is provided in the battery compartment 13 of the case 10. A battery rack 130 is provided into the energy storage container 100 for storing battery units 16 (see fig. 2). In order to understand the technical solution of the present invention more accurately, the structure of the battery holder 130 will be described first.

Referring to fig. 3 to 9, the battery holder 130 provided in the battery compartment 13 includes at least two support frames 131 and a battery bracket 132.

Referring to fig. 4, 6 and 8, two support frames 131 of the at least two support frames 131 are spaced and disposed opposite to each other, and the battery bracket 132 is disposed between the two support frames 131 disposed opposite to each other. The paired battery brackets 132 are respectively provided to two support frames 131 (see fig. 7) which are spaced and oppositely provided. The battery unit 16 is disposed on the battery bracket 132.

Referring to fig. 4, the support frame 131 of the battery rack 130 is connected between the top side beam 111 and the bottom frame 112 of the container body 10 in a supporting manner, so that the battery rack 130 and the main frame of the energy storage container 100 are connected into a whole, that is, the battery rack 130 and the container body 10 form a stable frame structure, thereby achieving the purpose of improving the overall structural strength of the energy storage container 100. A battery holder 132 for holding the battery unit 16 is provided between two support frames 131 arranged opposite to each other at an interval, and transmits a load to the case 10 through the support frames 131.

Preferably, in this embodiment, the support frame 131 includes a top cross beam 1311 and a support pillar 1312. The top cross member 1311 extends in the width direction D2 of the box 10. The support posts 1312 are support-connected between the base frame 112 and the top cross member 1311 in the height direction D3 of the box 10. Specifically, the bottom frame 112 includes a floor and support beams under the floor, and referring to fig. 5, the support pillars 1312 are specifically supported above the support beams, which can effectively increase the strength of the entire box 10, so that the battery rack 130 and the box 10 form a stable frame structure. In order to avoid liquid accumulation on the floor, the floor is configured to be inclined downward from the middle to the left and right sides in the embodiment shown in fig. 5, so as to prevent liquid accumulated under the battery rack 130 from affecting the safety of the battery unit 16. In addition, in the present embodiment, the supporting columns 1312 are welded and fixed to the bottom frame (floor) and the top cross beam 1311, and there is no need to additionally provide a connecting hole for connecting the supporting frame 131 on the floor in the battery compartment 13, which ensures the sealing performance of the floor and eliminates the potential hazards of floor leakage and liquid seepage.

It is understood that the battery holder 130 may include a plurality of support frames 131. The plurality of support frames 131 are spaced apart in a direction (length direction D1 in the drawing) perpendicular to a plane in which the support frames 131 are located, and a battery tray 132 is provided between adjacent and opposing two support frames 131 for storing the battery unit 16. The plurality of support frames 131 may be arranged at equal intervals, and the interval between two adjacent support frames 131 may be flexibly arranged according to actual situations.

Specifically, in the present embodiment, the battery holder 130 includes six support frames 131, and the six support frames 131 are disposed at equal intervals in the length direction D1.

The battery brackets 132 may be disposed in the spaces between two of the six support frames 131. Referring to fig. 2 and 4, the plurality of layers of battery brackets 132 may be disposed at intervals along the extending direction (height direction D3 in the drawing) of the support columns 1312. Providing multiple tiers of battery carriers 132 allows for more battery cells 16 to be loaded.

In order to improve the structural strength of the support frames 131, each support frame 131 includes a plurality of support pillars 1312 arranged at intervals in the extending direction (the width direction D2 in the drawing) of the top cross member 1311. Referring to fig. 2, 3 and 9, in the present embodiment, three support pillars 1312 are provided for each support frame 131 to improve the overall support strength of the battery holder 130. It is understood that three support columns 1312 is one solution adopted in the present embodiment, so that the battery holder 130 can simultaneously lift two battery units 16 (see fig. 2) arranged side by side and spaced apart in the width direction D2. The number of the supporting frames 131 and the number of the supporting columns 1312 in each supporting frame 131 can be set by those skilled in the art according to actual situations.

It is understood that the plurality of support frames 131 may be configured to have the same size and structure, or may be configured to have different sizes and structures. For example, considering that the support frame positioned in the middle needs to be matched with the support frames adjacent to both sides, the support frame positioned in the middle may be configured to have a thickness greater than the thicknesses of the two outermost support frames, so that the support frame positioned in the middle is configured to have higher support strength. Similarly, the supporting columns of each supporting frame can be arranged at equal intervals and can also be symmetrically arranged, and a plurality of supporting columns can be arranged to have different strengths. The design can be flexibly designed according to the actual situation by the technical personnel in the field.

In the present embodiment, two battery cells 16 are symmetrically placed in the width direction D2 on each layer of the battery holder 132. The battery cells 16 between the two support frames 131 are connected in series or in parallel to form a single battery cluster, improving energy density. One skilled in the art can flexibly set the number of battery cells 16.

Preferably, each battery carrier 132 is also provided with a battery stop 1324 (see fig. 5 or 9) for limiting the movement of the loaded battery unit 16.
