Description

Technical Field

[0001] This utility model relates to the field of battery pack storage and logistics technology, and in particular to an intelligent storage and retrieval device for battery packs. Background Technology

[0002] With the rapid development of the new energy industry, battery packs are being used more and more widely. Battery packs are typically large and heavy, making traditional manual forklift handling inefficient and posing safety hazards. Furthermore, battery packs are susceptible to thermal runaway during storage; if thermal runaway occurs, it can lead to fires or even explosions, causing serious consequences. Therefore, there is an urgent need for an intelligent and automated battery pack storage and retrieval system to improve efficiency, reduce costs, ensure safety, and effectively handle battery pack thermal runaway. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an intelligent storage and retrieval device for battery packs.

[0004] The present invention proposes an intelligent battery pack storage and retrieval device, which includes a battery pack storage area, a battery pack transfer area, a battery pack operation table, and a battery pack.

[0005] The battery pack storage area is equipped with shelves for storing battery packs for extended periods. The battery pack transfer area is equipped with a temporary storage area for transferring battery packs and a moving mechanism for moving battery packs to the battery pack storage area. The battery pack control panel is equipped with a touch screen and an emergency stop button. The battery packs are placed on a tray.

[0006] Furthermore, the battery pack storage area features a double-layer, three-dimensional shelf design. Partitions are installed on the sides of the battery pack placement area to prevent the spread of thermal runaway from the battery packs. A multi-media fire extinguishing device for handling thermal runaway is installed above the battery pack placement area. A sink is provided at the bottom of the battery pack placement area for securing trays and collecting fire extinguishing materials. An infrared sensor for detecting the presence of battery packs and a temperature sensor for detecting the battery pack temperature are installed at the rear of the battery pack placement area.

[0007] Furthermore, the battery pack transfer area is equipped with a position infrared sensor for detecting whether the battery pack is placed in the temporary storage area. The moving mechanism includes a mobile trolley for positioning and moving the battery pack and the tray. The mobile trolley moves in three directions via X-axis, Y-axis, and Z-axis tracks. Track motors for realizing the translation function are installed on the X-axis, Y-axis, and Z-axis tracks. The mobile trolley includes forks for picking up the tray below the battery pack, a camera for capturing the status and image of the battery pack, and a lighting lamp for providing supplementary lighting in dim conditions. The camera is positioned above the forks, and the lighting lamp is positioned above the camera.

[0008] Furthermore, the battery pack control panel is equipped with an alarm and a programmable controller. The alarm is located above the touch screen, which is located above the emergency stop button. The programmable controller is located below the touch screen. If thermal runaway occurs in the battery pack while it is being stored, the alarm will sound, and simultaneously, a multi-media fire extinguishing device in the battery pack storage area will inject extinguishing materials onto the thermally runaway battery pack to handle the thermal runaway. The multi-media fire extinguishing device contains various extinguishing materials, and it releases suitable extinguishing materials based on the electrochemical properties of the battery pack.

[0009] Furthermore, the camera is used to locate the battery pack positioning tray and periodically inspect the status of all battery packs in all compartments. When a battery pack is placed in the temporary storage area, the mobile trolley moves to its initial position in the temporary storage area via a track motor. The lights on the mobile trolley are turned on, the camera captures the position of the tray and the forklift, and inputs the positional deviation between the tray and the forklift to the programmable controller. The programmable controller converts the deviation into the number of rotations required by the track motor in each direction. The programmable controller sends the number of rotations to the track motor for movement correction of the mobile trolley. The touch screen displays the current position of the mobile trolley. After the battery pack is placed on the shelf, the operator sets the time interval for inspecting the battery pack status. After the mobile trolley periodically moves to the location of the battery pack to be inspected, the lights on the mobile trolley are turned on, the camera captures the status of the battery pack, and saves the image to local storage and the cloud for the operator to view.

[0010] The intelligent storage and retrieval device for battery packs proposed in this utility model has the following beneficial effects: it realizes the automation and intelligence of lithium battery pack storage and retrieval; it adopts multi-layer three-dimensional shelves, which improves the space utilization of the storage area; it is equipped with a human-machine interaction terminal, which facilitates operation and monitoring by operators; and it is equipped with a thermal runaway handling system, which can effectively handle the thermal runaway of lithium battery packs and ensure the safety of the storage area.
