Description

Technical Field

[0002] With the development of new energy technologies, energy storage containers have been increasingly widely used as a type of energy storage equipment. Energy storage containers are built on container facilities and are highly integrated energy storage equipment with many features such as high integration and small footprint.

[0003] China Patent Network has published an energy storage container with the publication number CN219067021U; the energy storage container includes: a box body and a wiring bracket, a maintenance layer is provided in the middle of the bottom of the box body, the maintenance layer extends along the length direction of the box body, battery layers are provided on both sides of the maintenance layer in the width direction of the box body, and the wiring bracket is provided in the maintenance layer, and the wiring bracket and the side wall of the maintenance layer jointly define the low-voltage communication line channel, low-voltage power line channel and high-voltage power line channel that are distributed at intervals. The energy storage container of the embodiment of the utility model pre-buries the wiring harness in the maintenance layer in the middle of the box body. Compared with the wiring method on both sides in the related art, the centralized wiring method of the energy storage container facilitates the installation and maintenance of the wiring harness. In addition, the low-voltage communication line channel, low-voltage power line channel and high-voltage power line channel are divided by the wiring bracket, which not only facilitates wiring, but also ensures the safe distance between different types of wiring harnesses to avoid mutual influence between the wiring harnesses;

[0004] The above device arranges the high-voltage wire harness and the low-voltage wire harness of the battery separately by providing a wiring bracket, but the wire harness cannot be centrally processed after arrangement, and it is rather cumbersome to organize them after wiring. Therefore, a liquid-cooled lithium battery energy storage container is proposed. Utility Model Content

[0038] Example 2

[0039] like Figure 1-Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the liquid cooling mechanism 2 includes a cooling plate 23, the bottom surface of the cooling plate 23 is fixedly connected to the bottom surface of the container 1, the cooling plate 23 is located between the two battery frames 41, and a cavity 25 is opened inside the container 1. A liquid inlet pipe 26 and a liquid outlet pipe 24 are arranged inside the cavity 25. The left sides of the liquid inlet pipe 26 and the liquid outlet pipe 24 both penetrate the inner wall of the cavity 25 and extend to the inside of the container 1. The left sides of the liquid inlet pipe 26 and the liquid outlet pipe 24 both penetrate the right side of the cooling plate 23 and extend to the inside of the cooling plate 23. A circulation box 22 is fixedly arranged on the top surface of the container 1, and a circulation pump 21 is fixedly arranged on the top surface of the container 1.

The bottom surface of the liquid outlet end of the circulation pump 21 penetrates the top surface of the container 1 and extends to the inside of the cavity 25. The bottom surface of the liquid outlet end of the circulation pump 21 is fixedly connected with the top surface of the liquid inlet pipe 26. The top surface of the liquid outlet pipe 24 is fixedly penetrated through the inside of the cavity 25 and extends to the top of the container 1. The left side of the liquid outlet pipe 24 is fixedly penetrated through the right side of the circulation box 22 and extends to the inside of the circulation box 22.

[0040] In this embodiment, by providing a liquid cooling mechanism 2, the interior of the container 1 can be cooled when the battery is working, so that the battery temperature is maintained at a stable temperature, thereby avoiding overheating of the battery and causing it to malfunction. During the cooling process, the refrigerant can circulate inside the refrigeration plate 23, which has a better cooling effect.

[0041] When in use, place the battery inside the battery frame 41, and pass the high-voltage wire and the low-voltage wire of the battery through the wire holes opened on the surface of the battery support plate 43 and the high-voltage wire groove and two low-voltage wire grooves opened on the bottom of the wiring frame 44 in turn, so that the high-voltage wire and the low-voltage wire of the battery can enter the high-voltage frame and the low-voltage frame.

By turning on the circulation pump 21, the refrigerant liquid inside the circulation box 22 can be extracted, so that the refrigerant liquid enters the inside of the refrigeration plate 23, and the refrigerant liquid inside the refrigeration plate 23 can circulate by providing a liquid outlet pipe 24.
