Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery swapping, and in particular, to a battery swapping method and system. Background Art

[0002] In the existing battery swapping service system, it is necessary to use power supply vehicles to realize the battery box scheduling between battery swapping stations. According to the actual battery swapping requirements of the battery swapping stations, the battery boxes with more power in the battery swapping stations with fewer battery swapping vehicles are transported to the battery swapping stations with greater battery swapping requirements. As the core carrier for transporting battery boxes, the power supply vehicle forms a fixed operation link with the battery swapping station through the on-vehicle battery compartment and the loading and unloading mechanism. The power supply vehicle usually shuttles between the battery centralized charging point (the charging point is usually set in a place with lower site cost and lower electricity price) and the battery swapping station according to the preset scheduling instructions, so as to realize the battery box replenishment of the battery swapping station through the power supply vehicle.

[0003] However, when the power supply vehicle provides battery boxes for the battery swapping station, usually the battery swapping station will first swap the battery boxes in the battery swapping station onto the battery swapping vehicle, so that the power supply vehicle needs to stay near the battery swapping station for a long time to prevent the battery boxes on the battery swapping station from being insufficient to meet the battery swapping requirements of the battery swapping vehicle, resulting in a low actual transportation efficiency of the power supply vehicle.

[0020] In this embodiment, in the traditional battery swapping operation process, when the battery swapping vehicle 04 enters the battery swapping area, there is no dynamic association and matching mechanism between the power amount Ai of the battery box 05 in the charging component 01 and the power amount Bj of the battery box 05 on the power supply vehicle 03. In the prior art, when the handling component 02 performs the replacement of the battery box 05, it usually preferentially calls the charged battery box 05 in the charging component 01 for replenishment, and the battery box 05 carried on the power supply vehicle 03 in the power supply area is only used as a spare inventory. This operation mode causes the power supply vehicle 03 to have to wait for a long time to unload the battery box 05 it carries, resulting in a long single operation time of the power supply vehicle 03 and a low power supply efficiency of the power supply vehicle 03. This embodiment discloses a battery swapping method, as Figure 1 shown, the battery swapping method may include steps S01 to S03, and the details of each step are as follows: As Figure 4As shown in the figure, the battery swapping system may include a charging component 01, a handling component 02, a battery box 05, a power delivery vehicle 03, and a battery swapping vehicle 04. The charging component 01 may include a frame unit 11 and a charging seat 12; the charging seat 12 is disposed within the space surrounded by the frame unit 11; the handling component 02 may include a large vehicle guide rail 21, a first small vehicle guide rail 23, a second small vehicle guide rail 24, a small vehicle body 26, and a grasping portion 29; one end of the large vehicle guide rail 21 may be slidably connected to one end of the frame unit 11 away from the charging seat 12; one end of the first small vehicle guide rail 23 may be slidably connected to the large vehicle guide rail 21, and the other end may extend in a direction away from the charging seat 12; the first small vehicle guide rail 23 may move along the length direction of the frame unit 11; the second small vehicle guide rail 24 may be slidably connected to the first small vehicle guide rail 23; the first small vehicle guide rail 23 may move along the width direction of the frame unit 11; the small vehicle body 26 may be slidably connected to the second small vehicle guide rail 24; the small vehicle body 26 may move along the width direction of the frame unit 11; the grasping portion 29 may be drivingly connected to the small vehicle body 26; the grasping portion 29 may drive the small vehicle body 26 to move along the height direction of the frame unit 11; the battery box 05 is detachably connected to and electrically connected to the charging seat 12; the handling component 02 may be used to disassemble and assemble the battery box 05 and the charging seat 12; the power delivery vehicle 03 may include a power delivery vehicle body 31 and a base 32; the base 32 is connected to the power delivery vehicle body 31; the base 32 is detachably connected to the battery box 05; the handling component 02 may be used to disassemble and assemble the battery box 05 and the base 32; the battery swapping vehicle 04 may include a battery swapping vehicle body 41 and a discharging seat 42; the battery swapping vehicle body 41 is connected to the discharging seat 42; the discharging seat 42 is detachably connected to and electrically connected to the battery box 05; the handling component 02 is used to disassemble and assemble the battery box 05 and the discharging seat 42; when the battery swapping vehicle 04 moves to the battery swapping area, the handling component 02 may carry the battery box 05 on the charging component 01 or the power delivery vehicle 03 to the battery swapping vehicle 04 to complete the battery swapping of the battery swapping vehicle 04.

[0021] In step S10, based on the battery swapping vehicle 04 entering the battery swapping area, the battery swapping information of the battery swapping system may be obtained; the battery swapping area may be the area projected in the direction of the charging seat 12 when the small vehicle body 26 of the handling component 02 moves to one side in the width direction of the frame unit 11, such as Figure 3The projection area at the bottom of the battery swapping vehicle 04 as shown. Among them, the battery swapping information may include the power Ai of the battery box 05 in the charging component 01, the turnover position of the battery box 05, and the power Bj of the battery box 05 on the power supply vehicle 03 in the power supply area; both i and j are natural numbers. For example, when there are 8 battery boxes 05 in the charging component 01, Ai can be A1~A8, which can respectively represent the power of the eight battery boxes 05 on the charging component 01. When there are 8 battery boxes 05 on the power supply vehicle 03, Bj can be B1~B8, which can respectively represent the power of the eight battery boxes 05 on the power supply vehicle 03. By respectively obtaining the power Ai of the battery box 05 in the charging component 01 and the power Bj of the battery box 05 on the power supply vehicle 03, a dynamic association matching mechanism can be formed between the power Ai of the battery box 05 in the charging component 01 and the power Bj of the battery box 05 on the power supply vehicle 03, which is convenient for the subsequent handling component 02 to perform the battery box 05 replacement operation. The power supply area can be an area on the side of the width direction of the frame unit 11 away from the battery swapping area and adjacent to the frame unit 11, such as Figure 3 The projection area at the bottom of the power supply vehicle 03 as shown towards the power supply vehicle 03.

[0022] In step S20, such as Figure 2 As shown, based on the battery swapping vehicle 04 being positioned in the battery swapping area and the turnover position being obtained, the handling component 02 can carry the low-power battery box 05 of the battery swapping vehicle 04 to the turnover position; among them, the turnover position can be an idle charging seat 12 not connected to the battery box 05 or an idle base 32 not connected to the battery box 05.

[0023] In step S30, based on the low-power battery box 05 being carried to the turnover position and max(Bj)≥max(Ai)*C, the handling component 02 can carry a battery box 05 with max(Bj) to the battery swapping vehicle 04; where C≥0.85. When the highest power of the battery box 05 on the power supply vehicle 03 reaches 85% or more of the highest power of the battery box 05 in the battery swapping station, the handling component 02 preferentially transfers the battery box 05 with max(Bj) on the power supply vehicle 03 to the battery swapping vehicle 04, so that the battery box 05 on the power supply vehicle 03 can be preferentially used, thereby reducing the residence time of the power supply vehicle 03 in the battery swapping area, enabling the power supply vehicle 03 to perform the transportation of the next batch of battery boxes 05 again, increasing the number of round trips of the power supply vehicle 03 from the charging point to the battery swapping area per unit time, and improving the power supply efficiency of the power supply vehicle 03. Step S10, step S20, and step S03 are executed in sequence.

[0024] In this embodiment, step S20 may include steps S21~S22, and the details of each step are as follows: In step S21, based on the fact that the battery swapping vehicle 04 is positioned in the battery swapping area and the turnover position is within the charging assembly 01, the handling assembly 02 can move the low-power battery box 05 of the battery swapping vehicle 04 through the battery swapping door 114 to the turnover position; the frame unit 11 can include a support beam 111, a housing 112, and a battery swapping door 114. The housing 112 can be movably connected to the battery swapping door 114. The support beam 111 can be connected to the housing 112. The charging seat 12 can be arranged in the space surrounded by the housing 112 and the battery swapping door 114 and is spaced from the support beam 111. The battery swapping door 114 can be arranged on the side of the housing 112 close to the battery swapping area. The bottom end of the battery swapping door 114 is higher than or flush with the top end of the battery box 05 in the charging seat 12, so as to avoid collision with the battery box 05 during the battery swapping process. The housing 112 can be movably connected to the battery swapping door 114. The battery swapping door 114 has a first state and a second state. The first state includes that the space surrounded by the housing 112 and the battery swapping door 114 is communicated with the external space of the frame unit 11 through the battery swapping door 114. The second state includes that the space surrounded by the housing 112 and the battery swapping door 114 is spaced from the external space of the frame unit 11. In some other embodiments, the width of the battery swapping door 114 can be 1.1 to 1.5 times the width of the battery box 05. A sensor can be arranged on the frame unit 11 to detect the position of the battery box 05 on the battery swapping vehicle 04 in the battery swapping area. In this way, the number of sensors can be small and the position of the battery box 05 on the battery swapping vehicle 04 in the battery swapping area can be accurately detected, saving costs.

[0025] In step S22, based on the fact that the handling assembly 02 moves the low-power battery box 05 of the battery swapping vehicle 04 through the battery swapping door 114 to above the turnover position, the handling assembly 02 can lower the low-power battery box 05 into the turnover position, realizing the transfer of the low-power battery box 05 on the battery swapping vehicle 04 to the turnover position, facilitating the subsequent placement of the max(Bj) battery box 05 on the battery swapping vehicle 04 by the handling assembly 02. Step S10, step S21, step S22, and step S30 are executed in sequence.

[0026] In this embodiment, step S20 can include step S23 to step S24, and the details of each step are as follows: In step S23, based on the fact that the battery swapping vehicle 04 is positioned in the battery swapping area and the turnover position is on the power supply vehicle 03, the handling assembly 02 can move the low-power battery box 05 of the battery swapping vehicle 04 through the battery swapping door 114 and the power supply door 113 in sequence to above the charging seat 12 of the idle charging assembly 01; the frame unit 11 can also include a power supply door 113, and the housing 112 can be movably connected to the power supply door 113. As Figure 6As shown in the figure, the power supply door 113 can be set on the side of the housing 112 away from the battery swapping area. The bottom end of the power supply door 113 is higher than or flush with the top end of the battery box 05 in the charging base 12. The power supply door 113 includes a third state and a fourth state. The third state includes that the space surrounded by the housing 112 and the power supply door 113 is communicated with the external space of the frame unit 11 through the power supply door 113. The fourth state includes that the space surrounded by the housing 112 and the power supply door 113 is spaced from the external space of the frame unit 11. In some other embodiments, the width of the battery swapping door 114 can be 1.1 to 1.5 times the width of the battery box 05. A sensor can be connected to the frame unit 11 to detect the position of the battery box 05 on the battery swapping vehicle 04 in the battery swapping area. In this way, the number of sensors can be small and the position of the battery box 05 on the battery swapping vehicle 04 in the battery swapping area can be accurately detected, saving costs. The width of the power supply door 113 can be k times the width of the battery swapping door 114, where k is the number of mounting seats on the power supply vehicle. k sensors can also be connected to the frame unit 11, and one sensor is used to detect the position of the battery box 05 on the power supply vehicle 03 in one power supply area. The frame unit 11 can be used to protect the charging base 12 and the battery box 05 in the charging base 12. If the width of the power supply door 113 is too small, the power supply vehicle 03 needs to frequently move its position to ensure that the handling component 02 can move the battery box 05 on the power supply vehicle 03 to the position of the power supply door 113. By increasing the width of the battery swapping door, the battery swapping efficiency of the battery swapping vehicle 04 is improved.

[0027] In step S24, based on the handling component 02, the low-power battery box 05 of the battery swapping vehicle 04 is successively moved above the idle charging base 12 through the battery swapping door 114 and the power supply door 113, and the handling component 02 can lower the low-power battery box 05 into the turnover position. Steps S10, S23, S24, and S30 are executed in sequence.

[0028] In this embodiment, the battery swapping method may further include steps S41 to S42, and the details of each step are as follows: In step S41, the number of battery swapping vehicles 04 in the waiting area is obtained; In step S42, based on the number of battery swapping vehicles 04 in the waiting area being greater than or equal to the set value, an instruction for the next power supply vehicle 03 to go to the power supply area is issued. The set value can be equal to the number of bases 32 on the power supply vehicle 03 or twice the number of bases 32 on the power supply vehicle 03. By monitoring the number of battery swapping vehicles 04 in the waiting area in advance, the power supply vehicle 03 can make an early response to ensure the normal operation of the battery swapping station. At the same time, preferentially using the battery box 05 on the power supply vehicle 03 (that is, the battery box 05 with a lower charging cost in the charging point) can save costs. Among them, steps S41 and S42 can be sequentially performed at any step.

[0029] In this embodiment, the battery swapping method may further include steps S43 to S44, and the details of each step are as follows: In step S43, based on the handling component 02, a battery box 05 with a capacity of max(Bj) is transported onto the battery swapping vehicle 04, and battery swapping information is obtained; wherein, the battery swapping information further includes the number of battery swapping vehicles 04 in the waiting area; In step S44, based on the condition that there is no battery swapping vehicle 04 in the waiting area, max(Bj) - min(Ai) ≥ X > 0, and the turnover position is on the power supply vehicle 03, the handling component 02 can move a battery box 05 with a capacity of min(Ai) to the turnover position; wherein, X can be the difference in power between the battery with the minimum power in the charging component 01 and the battery with the maximum power on the power supply vehicle; when there is no battery swapping vehicle 04 in the waiting area, in order to ensure that the power supply vehicle 03 stays for a short time, the battery box 05 with more power on the power supply vehicle 03 can be moved onto the power supply vehicle 03, so that the staying time of the power supply vehicle 03 in the battery swapping area is reduced, enabling the power supply vehicle 03 to transport the next batch of battery boxes 05 again, increasing the number of round trips of the power supply vehicle 03 from the charging point to the battery swapping area per unit time, and improving the power supply efficiency of the power supply vehicle 03.

[0030] In step S45, based on the handling component 02 moving a battery box 05 with a capacity of min(Ai) to the turnover position, the handling component 02 moves a battery box 05 with a capacity of max(Bj) into the charging component 01. At this time, the turnover position is on the power supply vehicle 03. When a subsequent battery swapping vehicle 04 arrives at the battery swapping area, the battery box 05 with less power on the battery swapping vehicle 04 can be directly moved onto the base 32 on the power supply vehicle 03. In order to ensure that the power supply vehicle 03 stays for a short time, the battery box 05 on the power supply vehicle 03 can be moved onto the charging component 01, increasing the number of round trips of the power supply vehicle 03 from the charging point to the battery swapping area per unit time, and improving the power supply efficiency of the power supply vehicle 03. Steps S10, S20, S30, S43, S44, and S45 are executed in sequence.

[0031] In this embodiment, the battery swapping method may further include step S46: In step S46, based on the fact that there is no battery swap vehicle 04 in the waiting area, 0<max(Bj)-min(Ai)<Z and the turnover position is located in the charging component 01, the transport component 02 moves a max(Bj) battery box 05 to the turnover position. When the difference between the minimum power battery in the charging component 01 and the maximum power battery on the power transmission vehicle is less than the set value, the battery box 05 on the battery swap vehicle 04 can be moved to the turnover position on the charging component 01. At this time, the turnover position is on the power transmission vehicle 03. When the subsequent battery swap vehicle 04 comes to the battery swap area, the low-power battery box 05 on the battery swap vehicle 04 can be directly moved to the base 32 on the power transmission vehicle 03. This makes the stay time of the power transmission vehicle 03 shorter, increases the number of round trips from the charging point to the battery swap area per unit time, and improves the power transmission efficiency of the power transmission vehicle 03. Steps S10, S20, S30, S43, and S46 are performed in sequence.

[0032] In this embodiment, the battery replacement method may further include step S47: In step S47, based on min(Ai)-max(Bj)≥0 and the turnover position is located in the charging assembly 01, a departure instruction can be issued to the power transmission vehicle 03 in the power transmission area. When the maximum power battery box 05 on the power transmission vehicle 03 is less than the minimum power battery box 05 in the charging assembly 01, the power transmission vehicle 03 can leave the battery swap area, so that the battery swap station can improve the working efficiency of the power transmission vehicle 03 under the premise of ensuring normal battery swapping of the vehicle. In other embodiments, when the power transmission vehicle 03 leaves the power transmission area, the next power transmission vehicle 03 can enter the power transmission area. Steps S10, S20, S30, S43, and S47 are performed in sequence.

[0033] In this embodiment, the battery replacement method may further include step S48: In step S48, based on the fact that the low-power battery box 05 is transported to the turnover position and max(Bj)≤max(Ai)*C, the transport component 02 can transport a battery box 05 with max(Ai) to the battery swap vehicle 04.
