[0021] In this embodiment, with the popularity of new energy vehicles 02, the demand for battery replacement of new energy vehicles 02 is increasing. Reserving a battery replacement channel between battery replacement vehicles 02 to achieve battery replacement of vehicles 02 will result in a weak battery replacement capacity of the battery replacement station. In order to meet the increasing battery replacement demand of new energy vehicles 02, it is usually necessary to increase the height or area of ​​the battery replacement station, which not only increases the volume of the battery replacement station, but also makes the layout of the battery replacement station difficult. This embodiment provides a battery replacement method, such as Figure 1 As shown, the battery replacement method may include steps S10 to S40, and each step is described in detail as follows: In step S10 , based on the first vehicle 02 arriving at the battery replacement area, the grabbing unit 12 can grab the battery box 03 of the first vehicle 02 .

[0022] In step S20, based on the gripping unit 12 gripping the battery box 03 of the first vehicle 02, the battery box 03 of the first vehicle 02 can be moved into the second compartment 112 and status data can be obtained. The status data may include the status of the charging seat 114. The gripping unit 12 is detachably connected to the first compartment 111 and the second compartment 112. Part of the gripping unit 12 can move in the first compartment 111 and the second compartment 112, so that the battery box 03 can be moved between the first compartment 111 and the second compartment 112 through the gripping unit 12. Figure 4As shown, the charging seat 114 in the first compartment 111 can be arranged in two columns or three rows. The second compartment 112 is detachably connected to the first compartment 111 along the first direction. The first column of charging seats 114 and the second column of charging seats 114 can be arranged in the first compartment 111 in sequence along the first direction. The first row of charging seats 114, the second row of charging seats 114, and the third row of charging seats 114 can be arranged in sequence along the second direction. The charging seats 114 in any column can be arranged vertically with the charging seats 114 in any row. The gap between adjacent charging seats 114 in the first compartment 111 can be smaller than the width of the battery box 03. The relatively dense arrangement of two columns and three rows can increase the number of battery boxes 03 in the battery swap station without increasing the volume of the battery swap station, thereby improving the battery swap capacity of the battery swap station. A-2=B, A is the number of charging seats 114 in the first compartment 111, and B is the number of battery boxes 03. By determining the number of free charging seats 114 in the first compartment 111, the grabbing unit 12 can grab the battery box 03 far away from the second compartment 112 through the position of the free charging seats 114. The battery box 03 in the first compartment 111 can be electrically connected to the charging seat 114. The bottom end of the battery box 03 grabbed by the grabbing unit 12 can be lower than or flush with the top end of the battery box 03 in the charging seat 114, preventing the grabbing unit 12 from grabbing too high and causing the grabbing unit 12 to shake violently, while also reducing the volume of the battery swap station. In some embodiments, the grabbing unit 12 may include a large vehicle rail 121, a large vehicle body 122, a telescopic rail 123, a small vehicle body 124 and a grabbing portion 125. Figure 2 As shown, the large vehicle body 122 can be slidably connected to the large vehicle guide rail 121. The small vehicle body 124 is detachably connected to the telescopic guide rail 123, and the grabbing portion 125 is detachably connected to the end of the telescopic guide rail 123 away from the small vehicle body 124, and the battery box 03 is grabbed by the mutual cooperation of the telescopic guide rail 123, the small vehicle body 124, and the grabbing portion 125.

[0023] In step S30, based on the state data including the initial state, the battery box 03 of the first vehicle 02 may be moved to an idle charging seat 114 in the second column. The initial state may include that two charging seats 114 in the second column are idle.

[0024] In step S40, based on moving the battery box 03 of the first vehicle 02 to the second row of free charging seats 114, the grabbing unit 12 can move the grabbable battery box 03 to the first vehicle 02. When there are many battery boxes 03, the battery swap station determines the position of the grabbable battery box 03 according to the placement position of the battery box 03 on the first vehicle 02, so that the grabbing unit 12 can grab a suitable battery box 03 to swap the battery for the battery swap vehicle 02. In turn, the battery swap station can realize the battery swap of the vehicle 02 when the battery boxes 03 at the battery swap station are densely packed, thereby improving the battery swap capacity of the battery swap station. In other embodiments, the battery box 03 on the first vehicle can be placed in the third row of the second column, and then the grabbing unit 12 can grab the battery box 03 in the second row of the first column and place it on the battery-swapping vehicle, so that when subsequent vehicles swap batteries, the grabbing unit 12 can directly grab any battery box 03 in the first compartment 111 without moving other battery boxes 03, thereby preventing the battery box 03 from being frequently moved on the charging seat 114, thereby reducing the service life of the charging seat 114.

[0025] In this embodiment, step S40 may include step S41, and step S41 may include steps S411 to S412. The details of each step are as follows: In step S411, the power of the grabbable battery box 03 can be obtained based on moving the battery box 03 of the first vehicle 02 to the second row of idle charging seats 114. By obtaining the power of the grabbable battery box 03, it is determined whether the grabbable battery box 03 can meet the battery replacement demand of the vehicle 02.

[0026] In step S412, based on the fact that the power of the grabbable battery boxes 03 in the first column is greater than the power of the grabbable battery boxes 03 in the second column, the grabbable battery boxes 03 in the first column can be moved to the first vehicle 02. Moving the grabbable battery boxes 03 with more power to the first vehicle 02 allows the battery boxes 03 to provide more energy to the first vehicle 02, so that the battery boxes 03 have a greater endurance.

[0027] In this embodiment, the battery replacement method may further include steps S51 to S54, each of which is described in detail as follows: In step S51, based on the second vehicle 02 arriving at the battery swapping area after the first vehicle 02 leaves the battery swapping area, the battery box 03 of the second vehicle 02 can be grabbed.

[0028] In step S52 , based on grabbing the battery box 03 of the second vehicle 02 , the battery box 03 of the second vehicle 02 can be moved into the second compartment 112 , so as to facilitate the subsequent placement of a new battery box 03 on the second vehicle 02 .

[0029] In step S53, based on the battery box 03 of the second vehicle 02 being moved into the second compartment 112, the battery box 03 of the second vehicle 02 can be moved into the first row of free charging seats 114. Placing the battery box 03 on the second vehicle 02 on the first row of free charging seats 114 can prevent the battery box 03 of the second vehicle 02 from affecting the grabbing unit 12 grabbing other battery boxes 03 and also facilitate the placement of the battery box 03 on the same row of charging seats 114 in the second row during the subsequent battery replacement process.

[0030] In step S54 , based on moving the battery box 03 of the second vehicle 02 to the vacant charging seat 114 in the first row, the grabbable battery box 03 in the second row can be moved to the second vehicle 02 .

[0031] In this embodiment, the battery replacement method may further include step S55: In step S55, based on the fact that there is no vehicle 02 in the battery swapping area after the second vehicle 02 leaves the battery swapping area, the grabbable battery box 03 in the first row of charging seats 114 can be moved to the second row of charging seats 114 in the same row as the battery box 03 of the second vehicle 02. When there is no vehicle 02 at the battery swapping station, the battery box 03 can be moved to a position close to the second compartment 112, so that when the subsequent battery swapping station swaps batteries for the battery swapping vehicle 02, the moving path of the grabbing unit 12 can be reduced, thereby improving the battery swapping efficiency of the battery swapping station.

[0032] In this embodiment, the battery replacement method may further include: Step S56, based on the grabbing battery box 03 in the first row of charging seats 114 being moved to the second row of idle charging seats 114 in the same row as the battery box 03 of the second vehicle 02, the battery box 03 of the first vehicle 02 can be moved to the idle charging seat 114 in the first row, preventing the battery box 03 of the first vehicle 02 from occupying the position of the charging seat 114 close to the second compartment 112, thereby reducing the moving path of the grabbing unit 12 grabbing the battery box 03 when other vehicles 02 are subsequently replacing batteries, thereby improving the battery replacement efficiency of the battery replacement station.

[0033] In this embodiment, step S40 may include step S42, and step S42 may include steps S421 to S422. The details of each step are as follows: Step S421, based on moving the battery box 03 of the first vehicle 02 to the idle charging seat 114 in the second row, the power of the grabbable battery box 03 can be obtained. Figure 3 As shown, there are grabbable battery boxes 03 in the first compartment 111 and the third compartment 113. The first compartment 111, the second compartment 112, and the third compartment 113 are detachably connected in sequence. A plurality of charging seats 114 are detachably connected in the hollow cavity of the third compartment 113. Figure 4As shown, the charging seats 114 in the third compartment 113 can be arranged in two columns or three rows. The charging seats 114 in any column are arranged vertically with the charging seats 114 in any row. The gap between adjacent charging seats 114 in the third compartment 113 is smaller than the width of the battery box 03 after charging. The two columns and three rows and relatively dense arrangement make it possible to increase the number of battery boxes 03 in the battery swap station without increasing the volume of the battery swap station, thereby improving the battery swap capacity of the battery swap station. C-3=B, C is the number of charging seats 114 in the first compartment 111 and the third compartment 113. The third column charging seats 114 and the fourth column charging seats 114 can be arranged in the third compartment 113 in sequence along the first direction. By determining the number of idle charging seats 114 in the first compartment 111, the grabbing unit 12 can grab the battery box 03 away from the second compartment 112 through the position of the idle charging seats 114.

[0034] Step S422, based on obtaining the power of the grabbable battery box 03, the grabbable battery box 03 with the highest power can be moved to the first vehicle 02, and the grabbable battery box 03 with more power can be moved to the first vehicle 02, so that the battery box 03 can provide more energy to the first vehicle 02, so that the battery box 03 has a greater endurance.

[0035] In this embodiment, the battery box 03 with the highest power that can be captured in step S422 may be in the third column.

[0036] The battery replacement method may also include: Step S61, based on the second vehicle 02 arriving at the battery exchange area after the first vehicle 02 leaves the battery exchange area, the battery box 03 of the second vehicle 02 can be moved to the second cabin 112 to facilitate the subsequent placement of a new battery box 03 on the second vehicle 02.

[0037] Step S62, based on moving the battery box 03 of the second vehicle 02 to the second compartment 112, the battery box 03 of the second vehicle 02 can be moved to the second row of idle charging seats 114. At this time, there is no idle charging seat 114 in the first compartment 111. When the low-power battery box 03 is charged, some heat will be released. When the temperature is too high, the charging battery box 03 needs to be cooled. When the temperature is too low, the battery box 03 that is not charged (i.e., it cannot release heat) needs to be kept warm. Therefore, the low-power battery box 03 can be placed in the same compartment, so that when the temperature of the battery box 03 is high during charging, only the first compartment 111 needs to be cooled, thereby achieving the purpose of energy saving.

[0038] In step S63 , the battery box 03 of the second vehicle 02 is moved to an idle charging seat 114 in the second row, so that the power of the grabbable battery box 03 can be obtained.

[0039] Step S64, based on D≥E*K, the battery boxes 03 that can be grabbed in the second row of charging seats 114 can be moved to the second vehicle 02. Wherein, D is the power of the battery box 03 that can be grabbed in the first compartment 111, E is the grabbable battery box 03 with the lowest power in the third compartment 113, and 0<K<1. When the power of the battery box 03 in the first compartment 111 is relatively high, the battery box 03 in the first compartment 111 can be grabbed first, so that a charging seat 114 without a battery box 03 can be reserved in the first compartment 111, and a battery replacement channel is reserved for grabbing other battery boxes 03 in the first compartment 111, so that the subsequent battery replacement station can grab other battery boxes 03 in the first compartment 111.

[0040] In this embodiment, in step S64, based on the fact that there is no battery swapping vehicle 02 in the battery swapping area after the second vehicle 02 leaves the battery swapping area, the battery box 03 of the first vehicle 02 and the battery box 03 of the second vehicle 02 can be moved to the first row of charging seats 114, so that when the subsequent battery swapping station swaps batteries for the battery swapping vehicle 02, the moving path of the grabbing unit 12 can be reduced, thereby improving the battery swapping efficiency of the battery swapping station.

[0041] In this embodiment, the battery replacement method may further include: Step S71, based on the third vehicle 02 arriving at the battery exchange area after the second vehicle 02 leaves the battery exchange area, the battery box 03 of the third vehicle 02 can be moved to the second cabin 112 to facilitate the subsequent placement of a new battery box 03 on the third vehicle 02.

[0042] Step S72, based on moving the battery box 03 of the third vehicle 02 to the second cabin 112, the battery box 03 of the third vehicle 02 can be moved to the third row of idle charging seats 114 to avoid the situation where there is no idle charging seat 114 in the first cabin 111, resulting in the battery box 03 in the first cabin 111 being unable to move subsequently.

[0043] In step S73, based on moving the battery box 03 of the third vehicle 02 to the third row of idle charging seats 114, the grabbable battery box 03 in the first compartment 111 can be moved to the third vehicle 02, so that there can be two idle charging seats 114 in the first compartment 111. At this time, the battery box 03 of the third vehicle 02 can be moved to the first compartment 111, so that when the temperature of the battery box 03 is high during charging, only the first compartment 111 needs to be cooled, thereby achieving the purpose of energy saving.

[0044] This embodiment provides a battery replacement system, which can be applied to the battery replacement method of any of the above embodiments. The battery replacement system may include: Battery box 03.
