[0018] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the present disclosure proposes a mobile battery replacement method, including: S1: when the first vehicle 4 enters the first area 1, obtaining first position information of the fully charged battery pack 7 on the first vehicle 4 and second position information of the first empty space 9 on the first vehicle 4; S2: When the second vehicle 5 enters the second area 2, third position information of the battery pack 8 to be charged on the second vehicle 5 is obtained; S3: moving the battery pack 8 to be charged from the second vehicle 5 to the first empty space 9 of the first vehicle 4 according to the second position information and the third position information, and forming a second empty space 10 on the second vehicle 5; S4: moving the fully-charged battery pack 7 of the first vehicle 4 to the second empty space 10 of the second vehicle 5 according to the first position information and the third position information.

[0020] It can be understood that when the first vehicle 4 enters the first area 1, the first position information of the fully charged battery pack 7 and the second position information of the first empty space 9 on the first vehicle 4 are obtained, so that the fully charged battery pack 7 can be accurately moved out of the first vehicle 4 using the first position information, and the battery pack 8 to be charged can be accurately moved to the first empty space 9 using the second position information; when the second vehicle 5 enters the second area 2, the third position information of the battery pack 8 to be charged on the second vehicle 5 is obtained, so that the battery pack 8 to be charged can be accurately moved out of the second empty space 10 using the third position information, and the fully charged battery pack 7 can be accurately moved to the second empty space 10.

[0021] Thus, the battery pack 8 to be charged is moved from the second vehicle 5 to the first empty space 9 of the first vehicle 4 according to the second position information and the third position information. At the same time, the fully charged battery pack 7 of the first vehicle 4 is moved to the second empty space 10 of the second vehicle 5 according to the first position information and the third position information, thereby realizing accurate replacement of the fully charged battery pack 7 on the first vehicle 4 and the battery pack 8 to be charged on the second vehicle 5, and meeting the efficient energy replenishment demand of the second vehicle 5. At the same time, since the fully charged battery pack 7 is placed on the flexibly movable first vehicle 4 and the battery pack 8 to be charged is placed on the flexibly movable second vehicle 5, the battery replacement positions of the fully charged battery pack 7 and the battery pack 8 to be charged are easy to change and adjust, thereby realizing flexible mobile battery replacement and meeting user needs.

[0022] It should be noted that the first vehicle 4 is used to load fully charged battery packs 7 and battery packs to be charged 8. It transports the fully charged battery packs 7 to the first area 1 so that the fully charged battery packs 7 can be replaced on the second vehicle 5, which transports the battery packs to be charged 8 to the charging area in a concentrated manner so that the battery packs to be charged 8 can be converted into fully charged battery packs 7. The specific type of the first vehicle 4 can be set according to actual needs and is not limited to this. For example, the first vehicle 4 can be a vehicle with a larger loading surface, such as a flatbed truck.

[0023] The second vehicle 5 is used to convert the electrical energy in the battery pack into mechanical energy, etc., to achieve different functions. The specific type of the second vehicle 5 can be set according to actual needs and is not limited to this. For example, the second vehicle 5 can be a heavy truck, a mining truck, a sprinkler truck, etc., wherein, for special vehicles such as heavy trucks with a cargo box brim, its battery pack 8 to be charged is located below its cargo box brim. Therefore, it is necessary to control the cargo box brim of the second vehicle 5 to open before the battery pack 8 to be charged is replaced by a fully charged battery pack 7, and control the cargo box brim of the second vehicle 5 to close after the battery pack 8 to be charged is replaced by a fully charged battery pack 7.

[0024] A fully charged battery pack 7 refers to a battery pack with a charge greater than a first set value, and a battery pack 8 to be charged refers to a battery pack with a charge not greater than a first set value. The first vehicle 4 is provided with at least one fully charged battery pack 7 and at least one first empty space 9. Specifically, the number of fully charged battery packs 7 and first empty spaces 9 can be one, two, three, four, etc., respectively. After a fully charged battery pack 7 is removed from the first vehicle 4, a first empty space 9 is added to the first vehicle 4. A battery pack 8 to be charged is moved into the first vehicle 4, and a first empty space 9 is reduced from the first vehicle 4. The second vehicle 5 is provided with at least one battery pack 8 to be charged. Specifically, the number of battery packs 8 to be charged can be one, two, three, four, etc., respectively. When a battery pack 8 to be charged is removed from the second vehicle 5, a second empty space 10 is added to the second vehicle 5. When a fully charged battery pack 7 is moved into the second vehicle 5, a second empty space 10 is reduced from the second vehicle 5.

[0025] The first position information is information indicating the position of the fully-charged battery pack 7, the second position information is information indicating the position of the first empty space 9, and the third position information is information indicating the position of the battery pack 8 to be charged. It can also be said that the third position information is information indicating the position of the second empty space 10. The types of the first position information, the second position information and the third position information can be set according to actual needs without limitation. By way of example, the first position information, the second position information and the third position information can all be coordinate data. For example, the first position information includes the x-axis coordinate, the y-axis coordinate and the z-axis coordinate of the fully-charged battery pack 7.

[0026] The first area 1 is used to accommodate the first vehicle 4, so as to facilitate the removal of the battery pack 8 to be charged and the movement of the fully charged battery pack 7 on the first vehicle 4. The second area 2 is used to accommodate the second vehicle 5, so as to facilitate the removal of the fully charged battery pack 7 and the movement of the battery pack 8 to be charged on the second vehicle 5. The specific arrangement of the first area 1 and the second area 2 can be set according to actual needs, and there is no limitation to this. For example, the first area 1 and the second area 2 are both areas close to rectangles, and the first area 1 and the second area 2 are arranged at intervals, and the length direction of the first area 1 is parallel to the length direction of the second area 2. Among them, after the relative position between the first area 1 and the second area 2 is determined, the actual position of the first area 1 and the second area 2 can be adjusted and changed arbitrarily to realize flexible mobile battery replacement.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, in step S3, moving the battery pack 8 to be charged from the second vehicle 5 to the first empty space 9 of the first vehicle 4 according to the second position information and the third position information includes: The battery pack 8 to be charged is moved from the second empty position 10 to the third area 3 according to the third position information, wherein the third area 3 is located between the first area 1 and the second area 2; The battery pack 8 to be charged is moved from the third area 3 to the first empty space 9 of the first vehicle 4 according to the second position information.

[0028] It can be understood that the battery pack 8 to be charged is moved from the second empty space 10 to the third area 3 between the first area 1 and the second area 2 according to the third position information, and the battery pack 8 to be charged is moved from the third area 3 to the first empty space 9 of the first vehicle 4 according to the second position information. This not only realizes the movement of the battery pack 8 to be charged from the second vehicle 5 to the first vehicle 4, but also utilizes the third area 3 in the middle to make the movement of the battery pack 8 to be charged more orderly and safe.

[0029] It should be noted that the third area 3 is used for temporarily storing the battery packs 8 to be charged. By using the third area 3, the overall movement of the battery packs 8 to be charged is more orderly and easier to realize automated operation, while ensuring that the movement of the battery packs 8 to be charged has higher safety. The specific layout of the third area 3 can be set according to actual needs and is not limited to this. For example, the third area 3 is an area close to a rectangle. The third area 3 is located between the first area 1 and the second area 2, and the length direction of the third area 3 is parallel to the length direction of the second area 2.

[0030] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, in step S3, moving the battery pack 8 to be charged from the second vehicle 5 to the first empty space 9 of the first vehicle 4 according to the second position information and the third position information further includes: Raise the battery pack 8 to be charged from the second empty position 10 to the first height; Rotate the battery pack 8 to be charged around a first angle in the vertical direction; Move the battery pack 8 to be charged from above the second empty space 10 to the third area 3 along the width direction of the third area 3; Moving the battery pack 8 to be charged along the length direction of the third area 3 by a first distance; Rotate the battery pack 8 to be charged around the vertical direction by a second angle; Move the battery pack 8 to be charged from the third area 3 to above the first empty space 9 along the width direction of the third area 3; The battery pack 8 to be charged is lowered from a first height to a first empty position 9 .

[0031] It can be understood that the battery pack 8 to be charged is raised from the second empty position 10 to the first height, and when the battery pack 8 to be charged is above the first empty position 9, the battery pack 8 to be charged is lowered from the first height to the first empty position 9, so that the battery pack 8 to be charged can be rotated without being restricted by the first vehicle 4 and the second vehicle 5, thereby ensuring the efficient and stable movement of the battery pack 8 to be charged from the second empty position 10 to the first empty position 9.

[0032] The battery pack 8 to be charged is rotated at a first angle around the vertical direction, and is rotated at a second angle around the vertical direction, so that the battery pack 8 to be charged can be flipped at a larger angle around the vertical direction, and the battery pack 8 to be charged can be efficiently and stably moved from the second empty position 10 to the first empty position 9 without occupying much space.

[0033] The battery package 8 to be charged is moved from above the second empty space 10 to the third area 3 along the width direction of the third area 3, and the battery package 8 to be charged is moved a first distance along the length direction of the third area 3, and then the battery package 8 to be charged is moved from the third area 3 to above the first empty space 9 along the width direction of the third area 3, so that the battery package 8 to be charged can pass through the third area 3 along a Z-shaped path, thereby ensuring efficient and stable movement of the battery package 8 to be charged from the second empty space 10 to the first empty space 9.

[0034] It should be noted that sequentially performing actions such as raising, rotating, and moving the battery pack 8 to be charged can make the overall turning radius smaller, the operation more flexible and safer, and the operating efficiency improved.

[0035] The first height can be set according to actual needs and is not limited thereto. The first height should not be set too small to prevent the rotation of the battery pack 8 to be charged from colliding with components on the first vehicle 4 and / or the second vehicle 5. At the same time, the first height should not be set too large to ensure that the movement of the battery pack 8 to be charged has high stability.

[0036] The first angle and the second angle can be set according to actual needs without limitation. For example, the first angle and the second angle can be 90 degrees respectively. That is to say, in the process of moving the battery pack 8 to be charged from the second empty space 10 to the first empty space 9, it needs to be rotated 90 degrees around the vertical direction first and then rotated 90 degrees around the vertical direction again, thus achieving an overall 180-degree flip.

[0037] The first distance can be set according to actual needs and is not limited thereto. The first distance is the distance between the first vacancy 9 and the second vacancy 10 in the length direction of the third region 3 .

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, in step S4, moving the fully charged battery pack 7 of the first vehicle 4 to the second empty position 10 of the second vehicle 5 according to the first position information and the third position information includes: Moving the fully-charged battery pack 7 from the first vehicle 4 to the third area 3 according to the first position information, wherein the third area 3 is located between the first area 1 and the second area 2; The fully-charged battery pack 7 is moved from the third area 3 to the second empty space 10 of the second vehicle 5 according to the third position information.

[0039] It can be understood that by moving the fully charged battery pack 7 from the first vehicle 4 to the third area 3 between the first area 1 and the second area 2 according to the first position information, and by moving the fully charged battery pack 7 from the third area 3 to the second empty space 10 of the second vehicle 5 according to the third position information, not only the movement of the fully charged battery pack 7 from the first vehicle 4 to the second vehicle 5 is realized, but also the movement of the fully charged battery pack 7 is made more orderly and safe by utilizing the third area 3 in the middle.

[0040] It should be noted that the third area 3 is also used to temporarily store the fully-charged battery packs 7. By utilizing the third area 3, the overall movement of the fully-charged battery packs 7 is more orderly and easier to realize automated operation, while ensuring that the movement of the fully-charged battery packs 7 is highly safe.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, in step S4, moving the fully charged battery pack 7 of the first vehicle 4 to the second empty position 10 of the second vehicle 5 according to the first position information and the third position information further includes: Lifting the fully charged battery pack 7 from the first vehicle 4 to a second height; Rotate the fully-charged battery pack 7 around the vertical direction by a third angle; Move the fully charged battery pack 7 from above the first vehicle 4 to the third area 3 along the width direction of the third area 3; Moving the fully-charged battery pack 7 along the length direction of the third area 3 by a second distance; Rotate the fully-charged battery pack 7 around the vertical direction to a fourth angle; Move the fully charged battery pack 7 from the third area 3 to above the second empty space 10 along the width direction of the third area 3; The fully-charged battery pack 7 is lowered from the second height to the second empty position 10 .

[0042] It can be understood that the fully charged battery pack 7 is raised from the first vehicle 4 to the second height, and when the fully charged battery pack 7 is above the second empty space 10, the fully charged battery pack 7 is lowered from the second height to the second empty space 10, so that the fully charged battery pack 7 can be rotated without being restricted by the first vehicle 4 and the second vehicle 5, thereby ensuring the efficient and stable movement of the fully charged battery pack 7 from the first vehicle 4 to the second empty space 10.

[0043] The fully-charged battery pack 7 is rotated at a third angle around the vertical direction, and is rotated at a fourth angle around the vertical direction, so that the fully-charged battery pack 7 can be flipped at a larger angle around the vertical direction, thereby enabling the fully-charged battery pack 7 to be efficiently and stably moved from the first vehicle 4 to the second empty space 10 without occupying much space.

[0044] The fully charged battery pack 7 is moved from above the first vehicle 4 to the third area 3 along the width direction of the third area 3, and the fully charged battery pack 7 is moved a second distance along the length direction of the third area 3, and then the fully charged battery pack 7 is moved from the third area 3 to above the second empty space 10 along the width direction of the third area 3, so that the fully charged battery pack 7 can pass through the third area 3 along a Z-shaped path, thereby ensuring efficient and stable movement of the fully charged battery pack 7 from the first vehicle 4 to the second empty space 10.

[0045] It should be noted that, by sequentially performing actions such as raising, rotating, and moving the fully-charged battery pack 7 , the overall turning radius can be made smaller, the operation can be made more flexible and safer, and the operating efficiency can be improved.

[0046] The second height can be set according to actual needs, and there is no restriction on this. The second height should not be set too small to avoid the rotation of the fully charged battery pack 7 colliding with the components on the first vehicle 4 and / or the second vehicle 5. At the same time, the second height should not be set too large to ensure that the movement of the fully charged battery pack 7 has high stability. Specifically, the second height can be the same as the first height.

[0047] The third angle and the fourth angle can be set according to actual needs without limitation. For example, the third angle and the fourth angle can be 90 degrees respectively. That is to say, in the process of moving the fully charged battery pack 7 from the first vehicle 4 to the second empty space 10, it is necessary to first rotate 90 degrees around the vertical direction and then rotate 90 degrees around the vertical direction again, thus achieving an overall 180-degree flip.

[0048] The second distance can be set according to actual needs and is not limited thereto. The second distance is the distance between the fully charged battery pack 7 in the first vehicle 4 and the second empty space 10 in the length direction of the third area 3 .

[0049] In some embodiments, the mobile battery replacement method further includes: Before the battery pack 8 to be charged is moved out of the second empty space 10, the second locking device of the second empty space 10 is controlled to be released; After the battery pack 8 to be charged moves to the first empty position 9, controlling the first locking device of the first empty position 9 to lock; After the fully-charged battery pack 7 moves to the second empty position 10 , the second locking device of the second empty position 10 is controlled to be locked.

[0050] It can be understood that, through the cooperation of the first locking device and the second locking device, it is possible to realize the battery swap between the battery pack to be charged 8 and the fully charged battery pack 7 while also making the battery pack to be charged 8 and the fully charged battery pack 7 have higher stability after the battery swap.

[0051] It should be noted that the first locking device and the second locking device are used to lock the battery pack respectively. The specific types of the first locking device and the second locking device can be set according to actual needs and are not limited to this. For example, the first locking device and the second locking device can be clamping structures respectively, that is, two relative clamping plates realize clamping and releasing the battery pack through a driving mechanism. The first locking device and the second locking device can also be other locking, snap-on and other structures.

[0052] In some embodiments, the mobile battery replacement method further includes: When the first vehicle 4 enters the first area 1, first identification information of the first vehicle 4 is obtained; When the first identification information and the first pre-stored information are the same, obtaining the position information of the first vehicle 4 according to the positioning system of the first vehicle 4; According to the position information of the first vehicle 4 , the first position information of the fully-charged battery pack 7 and the second position information of the first empty space 9 are acquired.

[0053] It can be understood that when the first vehicle 4 enters the first area 1, the first identification information of the first vehicle 4 is obtained, so as to compare the first identification information of the first vehicle 4 with the first pre-stored information, and when the first identification information and the first pre-stored information are the same, the first position information of the fully charged battery pack 7 and the second position information of the first empty space 9 are obtained, thereby avoiding the mismatch problem between the fully charged battery pack 7 and the battery pack to be charged 8, thereby ensuring the overall safe and stable battery replacement.

[0054] The position information of the first vehicle 4 is obtained according to the positioning system of the first vehicle 4, and the first position information of the fully charged battery pack 7 and the second position information of the first empty space 9 are obtained according to the position information of the first vehicle 4, thereby achieving accurate acquisition of the first position information and the second position information, and further ensuring stable battery exchange between the fully charged battery pack 7 and the battery pack to be charged 8.

[0055] It should be noted that the first identification information is information indicating the parameters of the first vehicle 4. The specific representation of the first identification information can be set according to actual needs and is not limited thereto. For example, the first identification information can be represented by a QR code, an RFID (Radio-Frequency-Identification) tag, etc. The first identification information can be identified using a corresponding probe. Among them, the first pre-stored information refers to the pre-stored identification information.

[0056] The positioning system of the first vehicle 4 is used to locate the first vehicle 4. Since the position of the positioning system is determined by the relative position between the fully-charged battery pack 7 and the first empty space 9, when the positioning system of the first vehicle 4 locates the position information of the first vehicle 4, it can obtain the first position information of the fully-charged battery pack 7 and the second position information of the first empty space 9 based on the position information of the first vehicle 4. The specific type of the positioning system in the first vehicle 4 can be set according to actual needs and is not limited to this. By way of example, the positioning system of the first vehicle 4 can be a GPS (Global-Positioning-System).

[0057] In some embodiments, the mobile battery replacement method further includes: When the second vehicle 5 enters the second area 2, second identification information of the second vehicle 5 is obtained; When the second identification information and the second pre-stored information are the same, obtaining the position information of the second vehicle 5 according to the positioning system of the second vehicle 5; According to the position information of the second vehicle 5 , the third position information of the battery pack 8 to be charged is acquired.

[0058] It can be understood that when the second vehicle 5 enters the second area 2, the second identification information of the second vehicle 5 is obtained, so as to compare the second identification information of the second vehicle 5 with the second pre-stored information, and when the second identification information and the second pre-stored information are the same, the third position information of the battery pack 8 to be charged is obtained, thereby avoiding the mismatch problem between the fully charged battery pack 7 and the battery pack 8 to be charged, thereby ensuring the overall safe and stable battery replacement.

[0059] The position information of the second vehicle 5 is obtained according to the positioning system of the second vehicle 5, and the third position information of the battery pack 8 to be charged is obtained according to the position information of the second vehicle 5, thereby achieving accurate acquisition of the third position information, and further ensuring stable battery exchange between the fully charged battery pack 7 and the battery pack 8 to be charged.

[0060] It should be noted that the second identification information is information indicating the parameters of the second vehicle 5. The specific representation of the second identification information can be set according to actual needs, and there is no limitation on this. For example, the second identification information can be represented by a QR code, an RFID tag, etc. The second identification information can be identified using a corresponding probe. Among them, the second pre-stored information refers to the pre-stored identification information.

[0061] The positioning system of the second vehicle 5 is used to locate the second vehicle 5. Since the relative position between the position of the positioning system and the second empty space 10 is determined, when the positioning system of the second vehicle 5 locates the position information of the second vehicle 5, it can obtain the third position information of the battery pack 8 to be charged based on the position information of the second vehicle 5. The specific type of the positioning system in the second vehicle 5 can be set according to actual needs and is not limited to this. For example, the positioning system of the second vehicle 5 can be GPS.

[0062] In some embodiments, the mobile battery replacement method further includes: When the second identification information and the second pre-stored information are the same, the power level of the battery pack 8 to be charged is obtained according to the management system of the second vehicle 5; The power of the battery pack 8 to be charged is compared with the preset power, and when the power of the battery pack 8 to be charged is not greater than the preset power, the position information of the second vehicle 5 is obtained according to the positioning system of the second vehicle 5 .

[0063] It can be understood that when the second identification information and the second pre-stored information are the same, obtaining the power of the battery pack 8 to be charged according to the management system of the second vehicle 5 can not only obtain the status of the battery pack 8 to be charged in real time and accurately, but also facilitate the implementation of subsequent battery replacement actions according to the power of the battery pack 8 to be charged, thereby ensuring that the battery pack 8 to be charged has a higher energy replenishment efficiency.

[0064] It should be noted that when the power of the battery pack 8 to be charged is not greater than the preset power, the battery swapping action between the fully charged battery pack 7 and the battery pack 8 to be charged will continue. When the power of the battery pack 8 to be charged is greater than the preset power, it means that there is still a lot of electrical energy in the battery pack 8 to be charged. At this time, the battery swapping action can be omitted and the second vehicle 5 can be moved to a fixed charging pile or charged using a mobile charging pile, thereby ensuring that the battery pack 8 to be charged has a higher energy replenishment efficiency.

[0065] It should be noted that the preset power is used to compare with the actual power of the battery pack 8 to be charged, and the preset power can be set according to actual needs, and there is no restriction on this. Among them, the specific value of the preset power should ensure that the battery pack 8 to be charged has the maximum energy replenishment efficiency, that is, comprehensively compare the charging time of the battery pack 8 to be charged and the replacement time of the battery pack 8 to be charged, as well as the idle state of the charging pile, the number of battery packs 8 to be replaced, etc.

[0066] The management system of the second vehicle 5 is used for managing the battery pack 8 to be charged. The specific type of the management system in the second vehicle 5 can be set according to actual needs and is not limited to this. For example, the management system of the second vehicle 5 can be a battery management system, a vehicle controller, etc.

[0067] like Figure 5As shown, the embodiment of the present disclosure also proposes a mobile battery replacement device 6, including: Control module 601, positioning module 602 and execution module 603; When the first vehicle 4 enters the first area 1, the control module 601 is used to obtain the first position information of the fully charged battery pack 7 on the first vehicle 4 and the second position information of the first empty space 9 on the first vehicle 4 by using the positioning module 602; When the second vehicle 5 enters the second area 2, the control module 601 is used to obtain the third position information of the battery pack 8 to be charged on the second vehicle 5 by using the positioning module 602; The control module 601 is used to control the execution module 603 according to the second position information and the third position information, so as to use the execution module 603 to move the battery pack 8 to be charged from the second vehicle 5 to the first empty space 9 of the first vehicle 4, and form a second empty space 10 on the second vehicle 5, and to control the execution module 603 according to the first position information and the third position information, so as to use the execution module 603 to move the fully charged battery pack 7 of the first vehicle 4 to the second empty space 10 of the second vehicle 5.

[0068] It can be understood that when the first vehicle 4 enters the first area 1, the control module 601 uses the positioning module 602 to obtain the first position information of the fully charged battery pack 7 and the second position information of the first empty space 9 on the first vehicle 4, so as to control the execution module 603 to accurately move the fully charged battery pack 7 out of the first vehicle 4 according to the first position information, and control the execution module 603 to accurately move the battery pack 8 to be charged to the first empty space 9 according to the second position information; when the second vehicle 5 enters the second area 2, the control module 601 uses the positioning module 602 to obtain the third position information of the battery pack 8 to be charged on the second vehicle 5, so as to control the execution module 603 to accurately move the battery pack 8 to be charged from the second empty space 10 according to the third position information, and move the fully charged battery pack 7 to the second empty space 10.

[0069] Therefore, the control module 601 controls the execution module 603 according to the second position information and the third position information, so as to use the execution module 603 to move the battery pack 8 to be charged from the second vehicle 5 to the first empty space 9 of the first vehicle 4. At the same time, the control module 601 controls the execution module 603 according to the first position information and the third position information, so as to use the execution module 603 to move the fully charged battery pack 7 of the first vehicle 4 to the second empty space 10 of the second vehicle 5, thereby realizing the precise replacement of the fully charged battery pack 7 on the first vehicle 4 and the battery pack 8 to be charged on the second vehicle 5, and meeting the efficient energy replenishment demand of the second vehicle 5. At the same time, since the fully charged battery pack 7 is placed on the flexibly movable first vehicle 4 and the battery pack 8 to be charged is placed on the flexibly movable second vehicle 5, the battery replacement positions of the fully charged battery pack 7 and the battery pack 8 to be charged are easy to change and adjust, thereby realizing flexible mobile battery replacement and meeting user needs.

[0070] It should be noted that the specific type of the mobile battery exchange device 6 can be set according to actual needs, and there is no restriction on this. For example, the mobile battery exchange device 6 can be a three-way forklift. The fork arm on the three-way forklift can move up and down, left and right, rotate, etc., and the three-way forklift as a whole can move forward and backward. Therefore, the three-way forklift and the fork arm on the three-way forklift can be used as an execution module 603. Furthermore, the length and shape of the fork arm can be set according to the working environment, and there is no restriction on this; the control part at the front of the three-way forklift can receive, process, and output data, etc., and can be used as a control module 601 and a positioning module 602, for example: AGV (Automated Guided Vehicle) system; the frame of the three-way forklift is welded from steel, has strength and stability, and is also equipped with a protective cover on the body to avoid impact and damage.

[0071] Among them, the advantages of using a three-way forklift as a mobile battery exchange device 6 are: the three-way forklift can be easily moved to different positions, making the layout of the entire mobile battery exchange more flexible; the use of a three-way forklift can easily realize the loading, unloading and transportation of battery packs, thereby improving the efficiency of battery exchange; the overall intelligent control is easy to realize, and automatic management and monitoring can be performed to improve the efficiency and safety of battery exchange; compared with traditional battery exchange machines, the equipment cost of the three-way forklift, the first vehicle 4, the second vehicle 5, etc. is lower, the construction cost is lower, and no additional equipment or system is required, so the maintenance cost is also lower; the battery exchange operation of the three-way forklift is safer and more reliable; due to the low cost and low operating cost, the investment payback period is short, and the cost can be recovered and the profit can be realized faster.

[0072] In summary, the mobile battery exchange device 6 of this embodiment has the characteristics of simple operation, high efficiency, safety and stability. It can effectively improve the operating efficiency of the vehicle and the energy-saving and emission reduction effects. It is a new type of battery exchange equipment with broad application prospects. In addition, the mobile battery exchange device 6 uses a three-way forklift to greatly shorten the battery exchange distance. As a mobile battery exchange station, using a three-way forklift as an operating equipment greatly reduces the overall construction time and improves the station construction efficiency.

[0073] Furthermore, to match the fork arm of the three-way forklift, both the battery pack 8 to be charged and the fully charged battery pack 7 are provided with reserved holes for the fork arm to pass through. Specifically, the reserved holes can be provided on the protective plate on the top of the battery pack; and, the fork arm of the three-way forklift can be provided with anti-slip sleeves or anti-slip clips to ensure safety during operation.

[0074] At the same time, in order to improve the stability of the battery pack after the battery is replaced, brackets can be set in the first empty space 9 and the second empty space 10. The brackets play a role in fixing the battery pack during transportation, further strengthening the support and protection capabilities of the battery pack, so that the battery pack can withstand higher loads and vibrations, and play the role of a charging bracket in a centralized charging station. The brackets are arranged horizontally and side by side on the first vehicle 4 to facilitate fork placement by a three-way forklift.

[0075] At the same time, it is necessary to arrange a roadbed box under the mobile battery exchange device 6, and pay attention to the smoothness of the ground to avoid equipment damage or other problems caused by uneven road surface or obstacles.

[0076] The specific application mode of the mobile battery exchange device 6 can be set according to actual needs, and there is no limitation on this. For example, a first vehicle 4 can be equipped with two sets of mobile battery exchange devices 6 and a second vehicle 5. Specifically, Figure 6 As shown, one group of mobile battery exchange devices 6 and the second vehicle 5 are located on one side of the first vehicle 4, and another group of mobile battery exchange devices 6 and the second vehicle 5 are located on the other side of the first vehicle 4. Thus, the first vehicle 4 can perform battery exchange on both sides. The multi-channel battery exchange method improves service efficiency. At the same time, for users, waiting time is shortened, congestion is reduced, battery exchange efficiency is improved, and experience is better. Multi-channel battery exchange can also better manage the inventory and usage of battery packs. Different batteries can be assigned to different channels to ensure that each channel has sufficient reserve batteries.
