Description

Technical Field

[0001] This utility model relates to the field of energy storage battery box technology, specifically to a battery tray. Background Art

[0002] Existing energy storage battery boxes, considering safety issues such as explosion prevention and flame retardancy, mostly adopt a top cover and bottom box structure, sealing the battery modules inside the battery box, which requires high cooling and heat dissipation.

[0003] With the improvement of the safety of energy storage battery modules and the development of energy storage battery cabinets, more attention needs to be paid to the stability of battery modules within the energy storage battery cabinet and the overall heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a novel battery tray that can be placed without a top cover, which is convenient for placement into an energy storage battery cabinet, has strong stability, and good heat dissipation.

[0005] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0006] A battery tray includes a tray base and at least one set of pressure strip assemblies mounted on the tray base. The tray base has a square structure with a raised edge on its outer periphery and a cooling assembly on the inner bottom surface of the tray base. The pressure strip assembly includes battery baffles vertically fixed to both ends of the top surface of the tray base and fixed pressure strips connected to the top of the two battery baffles at both ends. Battery slots are provided on the bottom surface of both ends of the fixed pressure strips.

[0007] Furthermore, the cross-section of the fixed pressure strip in the middle is rectangular and wavy.

[0008] Furthermore, the bottom of the battery baffle is fixed to the top surface of the tray base by two sets of studs.

[0009] Furthermore, a copper strip groove is provided on the inner side of the battery baffle, and copper strip fixing bolts corresponding to the copper strip groove are provided on the battery baffle.

[0010] Furthermore, the cooling assembly includes a heat-conducting plate laid on the inner bottom surface of the tray base, and a cooling medium flow channel is provided between the inner bottom surface of the tray base and the heat-conducting plate.

[0011] Furthermore, air-cooling ventilation holes are provided on the heat-conducting plate.

[0012] Furthermore, the heat-conducting plate is made of sheet molding compound (SMC) material.

[0013] Furthermore, a cooling medium inlet / outlet module is provided at one end of the tray base to interface with the cooling components.

[0014] Furthermore, a grounding bolt is installed through the raised edge of the tray base.

[0015] The battery trays of this utility model are installed in the drawers of the energy storage box battery cabinet. Each battery tray uses multiple sets of pressure strip components to fix multiple battery modules in the battery tray separately, ensuring reliable installation of the battery modules. This replaces the method of internal fixation using only the top cover. The structure is scientific and reasonable, and the fixation is reliable. The overall heat dissipation of the battery modules is achieved through the external energy storage battery cabinet, resulting in good heat dissipation effect. Attached Figure Description

[0024] like Figures 1 to 3 As shown, a battery tray of this utility model includes a tray base 1 and at least one set of pressure strip assemblies 2 installed on the tray base 1. The tray base 1 has a square structure with a raised edge 11 on its outer periphery and a cooling assembly on the inner bottom surface of the tray base 1. The pressure strip assembly 2 includes battery baffles 21 vertically fixed at both ends of the top surface of the tray base 1 and a top fixing pressure strip 22 fixed at both ends of the battery baffles 21. Battery slots 221 are provided on the bottom surface of both ends of the fixing pressure strip 22. The battery slots 221 limit and fix the top of the battery module 4, ensuring that the battery module 4 is fixed in position within the tray base 1.

[0025] Preferably, the cross-section of the middle part of the fixing strip 22 is rectangular and wavy, which makes it easier to adapt to the top structure of the battery module 4 and improves the heat dissipation effect.

[0026] In some embodiments, the bottom of the battery baffle 21 is fixed to the top surface of the tray base 1 by two sets of studs. The battery baffle 21 is used to restrict the arrangement of the battery modules 4, and at the same time, it is used to position and install the fixing strip 22 and the conductive components connected to the battery modules 4.

[0027] Preferably, a copper strip groove is provided on the inner side of the battery baffle 21, and a copper strip fixing bolt 23 corresponding to the copper strip groove is provided on the battery baffle 21. The copper strip fixing bolt 23 is used to fix the conductive copper strip, ensuring the stability of the current of the power module 4 and keeping the internal structure of the battery tray in an orderly and fixed manner.

[0028] In some embodiments, the cooling assembly includes a heat-conducting plate 3 laid on the inner bottom surface of the tray base 1, a cooling medium flow channel is provided between the inner bottom surface of the tray base and the heat-conducting plate, and a cooling medium inlet / outlet module 12 connected to the cooling medium flow channel is provided at one end of the tray base 1. The cooling medium can be water-cooled or air-cooled. In embodiments using air cooling, air-cooling ventilation holes are provided on the heat-conducting plate 3 for introducing cooling air medium into the battery tray in air-cooling mode.

[0029] In some embodiments, the heat-conducting plate 3 is made of sheet molding compound (SMC) material, which has a lightweight effect, reduces the overall weight of the battery tray, and improves strength. Since there is no full-coverage top cover, the overall heat dissipation effect still meets the heat dissipation requirements.

[0030] In some embodiments, a grounding bolt 13 is installed through the protrusion 11 of the tray base 1. The grounding bolt 13 is used for electrostatic protection of the electrical components and the housing of the battery module 4 in the tray base 1.

[0031] The specific embodiments described herein are merely illustrative of the invention and are not intended to limit it. Those skilled in the art can make modifications to these embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of this invention.
