[0039] See Figures 1 to 5 As shown, an embodiment of the present application provides a battery swapping station, including: a fixed battery swapping station 1, a mobile station passage 2, a battery swapping vehicle passage 3, a mobile station 4, and a battery swapping robot 5. The fixed battery swapping station 1 includes a box shell and a plurality of battery boxes a. Each battery box a is disposed within the box shell, and the battery boxes a are sequentially arranged along the length direction of the box shell. The mobile station passage 2 and the battery swapping vehicle passage 3 are respectively disposed on both sides of the box shell along the width direction. The mobile station 4 can dock at the mobile station passage 2. The mobile station 4 has a vehicle body, a traveling mechanism, and a battery box a. The traveling mechanism is disposed on the vehicle body, and the battery box a is disposed on the vehicle body. The battery swapping robot 5 is disposed within the box shell. The battery swapping robot 5 has a telescopic arm 51 and a battery gripper 52 disposed on the telescopic arm 51. The telescopic arm 51 can perform bidirectional telescopic movement along the width direction of the box shell. The telescopic arm 51 can drive the battery gripper 52 to move to the mobile station passage 2 or the battery swapping vehicle passage 3. The battery swapping robot can directly transfer the battery box a on the mobile station 4 to the battery swapping vehicle 10 parked within the battery swapping vehicle passage 3.

[0040] The battery swapping robot 5 configured in the battery swapping station provided by the embodiment of the present application has a telescopic arm 51 with bidirectional telescoping. The battery swapping robot 5 can reciprocate between two channels. The battery swapping vehicle channel 3 is used solely for vehicle battery swapping, replacing the battery box a in the station with the vehicle. The mobile station channel 2 is used to dock the mobile station 4. The battery swapping robot 5 can obtain power from the mobile station 4 or the fixed battery swapping station 1, and load the battery swapping vehicle 10 (electric vehicle with replaceable battery box) in the battery swapping vehicle channel 3. By adopting the dual-channel solution, both the mobile station 4 and the fixed battery swapping station 1 can serve as backup battery workstations. The battery swapping robot can decide to replace the battery box a on the mobile station 4 or the fixed battery swapping station 1 according to the operation requirements. The mobile station 4 has a traveling mechanism and can flexibly rotate among multiple fixed battery swapping stations 1, thus flexibly increasing the peak service capacity of the fixed battery swapping station 1.

[0041] In some possible implementation solutions, the battery swapping station includes a mobile station shielding shed 6 and a battery swapping vehicle shielding shed 7. The mobile station shielding shed 6 and the battery swapping vehicle shielding shed 7 are respectively arranged on both sides of the box shell along the width direction. At least part of the mobile station channel 2 is formed between the mobile station shielding shed 6 and the box shell, and at least part of the battery swapping vehicle channel 3 is formed between the battery swapping vehicle shielding shed 7 and the box shell. The mobile station shielding shed 6 serves to protect the mobile station 4 docked below. The battery swapping vehicle shielding shed 7 serves to shield and protect the battery swapping vehicle 10 waiting for battery swapping below.

[0042] In some possible implementation solutions, combined Figure 1 with Figure 2 as shown, along the length direction of the fixed battery swapping station 1, the extending length of the mobile station shielding shed 6 is greater than that of the battery swapping vehicle shielding shed 7. A plurality of battery boxes a are installed on the mobile station 4, and its length dimension is much larger than that of an ordinary battery swapping vehicle. Therefore, the mobile station shielding shed 6 has a longer length to ensure covering all the battery boxes a on the mobile station 4.

[0043] In some possible implementation solutions, the vehicle body has a vehicle head and a chassis connecting the vehicle head. A plurality of battery boxes a are arranged on the chassis. The length of the mobile station shielding shed 6 is not less than the length of the chassis, so that when the mobile station 4 docks in the mobile station channel 2, all the battery boxes a on the mobile station 4 can be within the coverage of the mobile station shielding shed 6 and can be effectively protected.

[0044] Optionally, a plurality of battery bases 81 are provided on both the chassis and the fixed battery swapping station 1. The battery bases 81 are all used for installing the battery boxes a. The number of battery bases 81 on the chassis is not more than that on the fixed battery swapping station 1. The battery boxes a on the movable station 4 can also be not loaded on the fixed battery swapping station 1 and can be directly grabbed by the battery swapping robot 5 and loaded onto the battery swapping vehicle that needs battery swapping. Some empty spaces can be reserved on the fixed battery swapping station 1 and the movable station 4 to facilitate the transfer of the battery boxes a during the battery swapping process, so that the battery swapping robot 5 can smoothly carry out the battery swapping task.

[0045] In some possible implementation manners, a first door opening is provided on one side of the box shell facing the battery swapping vehicle passage 3, and a second door opening is provided on one side of the box shell facing the movable station passage 2. In the length direction of the fixed battery swapping station 1, the extension length of the first door opening is less than that of the second door opening. The second door opening has a longer length, and all the battery boxes a on the movable station 4 can be exposed to the second door opening, so that each battery box a is within the grasping range of the battery swapping robot 5. The number of battery boxes a on the battery swapping vehicle is small, and the size of the first door opening is small, which can meet the space requirements for replacing the battery boxes a on the battery swapping vehicle 10.

[0046] Specifically, the length of the second door opening is not less than the distance between the two battery bases 81 at both ends on the chassis. The battery swapping robot 5 can smoothly grab all the battery boxes a on the chassis of the movable station 4.

[0050] In some possible embodiments, the energy storage system 8 includes a battery base 81, and the battery box a of the energy storage system 8 is detachably connected to the battery base 81. The energy storage system 8 of the present application adopts a replaceable battery mode, which is beneficial to utilizing idle batteries, reduces costs, and effectively solves the problem of insufficient power capacity of the fixed battery swapping station 1.

[0051] The energy storage system 8 can be charged from the power grid through the PCS module, or can also meet the rapid charging demand of the energy storage charging pile by replacing the battery box a. When there is power in the power grid, during the low electricity consumption period, the battery box a is charged through the PCS module. During the high electricity consumption period, the battery phase of the energy storage system 8 can discharge to the power grid through the PCS module to achieve the function of peak shaving and valley filling, saving electricity costs.

[0052] In some possible embodiments, the battery base 81 has a first connector, and the first connector is electrically connected to the grid connection cabinet 9.

The battery box a of the external energy storage system 8 is universal, and the battery box a in the fixed battery swapping station 1 can be directly installed on the energy storage system 8. Some old battery boxes a can be reused for the energy storage system 8.

[0054] In some possible embodiments, the battery box a of the energy storage system 8 has a hoisting fitting part, and the hoisting fitting part can be a lifting lug or a hoisting fitting frame provided on the battery box a, which is convenient for hoisting with a hoisting tool for assembly or disassembly.
