Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a transfer device for a battery plug-in box. Background Art

[0002] A battery cluster is a battery assembly that is connected in series, parallel or series-parallel by battery cells, and is connected to an energy storage inverter and ancillary facilities to achieve independent operation. It should also include components such as a battery management system, monitoring and protection circuits, and electrical and communication interfaces. Energy storage equipment is a new energy device that stores battery plug boxes in an energy storage rack. Specifically, the battery plug boxes are placed in the plug box placement slots of the plug box placement rack of the energy storage rack. The battery plug box is the smallest energy unit of a battery cluster. The battery cluster includes multiple battery plug boxes, which have the advantages of convenient maintenance. The battery plug box includes a box body, a battery module located in the box body, and a fan installed on the front wall of the box body. Air inlets are provided on both sides of the box body. The air duct during cooling is that the cold fluid enters the box body from both sides of the box body, passes through the large surface of each battery cell of the battery module, and converges in the middle of the box body. Finally, the cold fluid is drawn away by the fan.

[0003] At present, the installation of battery clusters is done by lifting the battery plug-in box to the plug-in box installation platform through a lifting device with a one-way degree of freedom, and manually pushing the plug-in box to the installation position. The lifting device has few adjustable directions and requires more human intervention. Alternatively, the assembler stands on the tray where the plug-in box is placed and pushes the plug-in box to the energy storage rack, manually adjusts the angle to position the plug-in box, and then fixes the plug-in box with bolts. During the assembly process, there are certain safety issues during the high-altitude operation because the assembler has to stand on the pallet and be lifted together with the plug-in box or the person and the plug-in box are lifted separately. At the same time, during the plug-in box assembly process, the positioning of the plug-in box and the energy storage rack requires human intervention. The plug-in box is heavy, and the installation plane of the plug-in box installation point must correspond one-to-one with the installation point on the energy storage rack. Adjustment can only be done by manpower, which is inefficient and consumes the physical strength of the assembler. Utility Model Content
