[0059] Stacker 1: The technical solution of this application uses the stacker as a logistics and storage equipment to carry out efficient cargo handling and stacking operations in a limited space. In the battery-swap stereo garage in the technical solution of this application, the stacker is used to transfer vehicles between parking spaces, especially battery-swap vehicles 3. When the stacker is in operation, it can keep the pallet or other carrier carrying the vehicle stable to ensure the safety of the vehicle during the transfer process.

[0060] Battery exchange system: The battery exchange system is the key part of the battery exchangeable stereo garage in the technical solution of this application, including two main parts: battery exchange equipment 2 and battery exchange vehicle 3. The following will introduce them separately:

[0061] Battery swapping device 2: This device is set in a parking space of the battery swapping stereo garage in the technical solution of this application, and its main function is to perform battery swapping operation on the battery swapping vehicle 3. The main purpose of the battery swapping operation is to quickly replace the battery of the electric vehicle and replace it with a fully charged battery to reduce the waiting time for charging and improve the efficiency of vehicle use.

[0062] Battery swap vehicle 3: Its battery is designed to be quickly disassembled and replaced. When this vehicle needs to be replaced, it can be transported by a stacker to a parking space where the battery swap equipment is located for battery replacement.

[0063] Based on the above device modules, the working process of the battery-swappable stereo garage in the technical solution of this application in this specific embodiment is as follows:

[0064] Step 1: When the battery-swapping vehicle 3 needs to have its battery replaced, the vehicle enters the stereoscopic parking garage.

[0065] Step 2: The stacker 1 transfers the battery swapping vehicle 3 to the parking space equipped with the battery swapping equipment 2 according to the system's scheduling.

[0066] Step 3: During the battery swapping process, the stacker 1 maintains the posture of carrying the battery swapping vehicle 3 to ensure the smooth progress of the battery swapping operation.

[0073] The base can be raised and lowered to facilitate raising the height of the battery swap mechanism, so that the battery swap mechanism can reach the battery installation area on the battery swap vehicle 3 more quickly and flexibly.

[0074] In an embodiment of the present application, there are two battery exchange devices 2, which are respectively arranged in two adjacent parking spaces.

[0075] Each battery replacement potential is provided with a battery replacement device 2, which can improve the battery replacement efficiency.

[0076] In an embodiment of the present application, the parking spaces where the two battery exchange devices 2 are located are connected so that the stacker 1 can remain in an extended state and directly transfer to the top of another battery exchange device 2 to perform a battery installation operation after the battery removal operation is completed.

[0078] In the embodiment of the present application, the stacker 1 includes a liftable and movable car and a telescopic mechanism disposed in the car and capable of extending and retracting along both sides.

[0079] There are two battery exchange devices 2, and they are arranged in any plane at both ends along the telescopic direction of the telescopic mechanism in multiple parking spaces.

[0080] When replacing the battery of a vehicle, the telescopic mechanism extends out to support the battery-swapping vehicle 3 to the top of the battery-swapping equipment 2. After the battery-swapping is completed, the telescopic mechanism retracts to avoid occupying the space in the garage. The distribution of the battery-swapping equipment 2 facilitates close contact with the battery-swapping vehicle 3 to achieve rapid battery replacement.

[0081] In an embodiment of the present application, the battery exchange system also includes a battery transport mechanism and a battery storage mechanism. The battery storage mechanism and the battery transport mechanism are arranged in a parking space adjacent to the battery exchange equipment 2 in the plane.

[0082] The battery transport mechanism obtains the battery from the battery storage mechanism and transports it to the battery exchange device 2. The battery transport mechanism, the battery storage mechanism and the battery exchange device 2 are adjacent to each other, which can facilitate the rapid transport of the battery, improve the battery transport efficiency, and further improve the battery exchange efficiency.

[0083] In an embodiment of the present application, the battery transfer mechanism can be moved on the top wall of the parking space, and its moving trajectory is from above the battery exchange device 2 to above the battery storage mechanism.

[0084] The battery transfer mechanism is arranged on the top wall of the parking space, and the battery can be hoisted from a high place to avoid occupying the flat space of the parking space.

[0085] In an embodiment of the present application, a battery storage mechanism and a battery transfer mechanism are arranged in a parking space which is vertically adjacent to the battery exchange device 2 and located above the battery exchange device 2. The bottom wall of the parking space has an avoidance opening so that the battery transfer mechanism can transfer the battery between the battery exchange device 2 through the avoidance opening.

[0086] The battery storage mechanism and the battery transfer mechanism are arranged adjacent to the battery replacement device 2 above and below, and the battery transfer is completed through the avoidance opening, thereby realizing efficient and portable battery transfer.

[0087] In the embodiment of the present application, multiple potential changers are provided and are located in parking spaces at the same floor height;

[0088] Multiple battery-swapping points are set to simultaneously satisfy the battery-swapping needs of multiple battery-swapping vehicles 3, thereby improving the battery-swapping efficiency.

[0089] The second aspect of the present application provides a battery replacement method for a battery-replaceable stereoscopic carport based on any one of the embodiments of the first aspect, including:

[0090] S100: Control the stacker 1 to move the battery swapping vehicle 3 to the parking space where the battery swapping equipment 2 is located.

[0091] In a specific application scenario, when the battery swapping vehicle 3 enters the multi-story parking garage, the system needs to first identify and locate it to ensure that its specific location is known; the system calculates the optimal path based on the location of the vehicle and the location of the parking space where the battery swapping equipment 2 is located, and dispatches the stacker 1 to the location of the battery swapping vehicle 3; after the stacker 1 arrives at the location of the battery swapping vehicle 3, it uses its robotic arm or other clamping device to capture the vehicle and safely transfer it to the parking space where the battery swapping equipment 2 is located.

[0092] S200: Control the stacker 1 to maintain the state of carrying the battery-swapping vehicle 3 and cooperate with the battery-swapping equipment 2 to perform the battery-swapping operation.

[0093] In a specific application scenario, the stacker 1 accurately positions the battery swap vehicle 3 within the operating range of the battery swap device 2, and cooperates with the battery swap device 2 to ensure the smooth progress of the battery swap operation. During the battery swap process, the stacker 1 needs to maintain the state of carrying the battery swap vehicle 3 to ensure the stability of the vehicle and prevent displacement or tilting during the battery swap process, which affects the battery swap effect. At the same time, the system needs to monitor the battery swap process in real time. If necessary, the stacker 1 needs to be able to make adjustments quickly to ensure the accuracy and safety of the battery swap operation.

[0094] S300: After the battery swap is completed, the stacker 1 is controlled to transfer the battery swap vehicle 3 to another parking space.

[0095] According to the battery replacement method provided in the second aspect of the embodiment of the present application, the multi-story parking garage is combined with the battery replacement system so that the multi-story parking garage integrates parking and battery replacement functions, and the stacker 1 in the multi-story parking garage is utilized to participate in the battery replacement process. There is no need to set up a separate battery replacement potential, which can reduce the battery replacement cost and improve the battery replacement efficiency.

[0096] In a specific application scenario, the system first needs to confirm that the battery swap operation has been completed and the vehicle's battery has been successfully replaced. Stacker 1 captures the battery swap vehicle 3 again and transfers it to another designated parking space. This parking space can be pre-designated by the owner or automatically allocated by the system based on the current parking space occupancy. Finally, after the vehicle is securely placed in the parking space, stacker 1 releases the vehicle, completing the entire process.

[0097] Through the above scheme, the battery-swap stereo garage realizes fast, safe and efficient battery-swap services for battery-swap vehicles, greatly improving the convenience and efficiency of electric vehicle use.
