Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping technology, and more specifically, to a battery swapping method and system. Background Technology

[0002] In the existing battery swapping service system, battery pack scheduling between swapping stations is achieved through power delivery vehicles. Based on the actual swapping needs of each station, battery packs with higher capacity from stations with fewer vehicles are transported to stations with greater demand. Power delivery vehicles, as the core carriers for battery pack transportation, form a fixed operational link with the swapping stations through their onboard battery compartments and loading / unloading mechanisms. These vehicles typically travel between centralized battery charging points (usually located in areas with low site costs and low electricity prices) and swapping stations according to pre-set scheduling instructions, thereby replenishing the battery packs at the swapping stations.

[0003] However, when power supply vehicles provide battery boxes to battery swapping stations, the stations usually prioritize swapping their own battery boxes to the vehicles. This requires the power supply vehicles to be stationed near the stations for extended periods to prevent the battery boxes at the stations from being insufficient to meet the swapping needs of the vehicles, resulting in low actual transportation efficiency for the power supply vehicles.

[0020] Based on the fact that there is no battery swapping vehicle in the waiting area, max(Bj)-min(Ai)≥X>0 and the turnover position is located on the power supply vehicle, the handling component moves a min(Ai) of the battery box to the turnover position;

[0021] The transport assembly moves a battery box of min(Ai) to the turnover position, and moves a battery box of max(Bj) into the charging assembly.

[0022] In some embodiments, the battery swapping method further includes:

[0023] Based on the fact that there are no battery swapping vehicles in the waiting area, 0 < max(Bj) - min(Ai) < Z, and the turnover position is located within the charging component, the transport component moves one max(Bj) of the battery box to the turnover position.

[0024] In some embodiments, the battery swapping method further includes:

[0025] Based on the condition that min(Ai)-max(Bj)≥0 and the turnover position is located within the charging component, a departure command is issued to the power supply vehicle within the power supply area.

[0026] In some embodiments, the battery swapping method further includes:

[0027] Based on the fact that the battery box with low power is transported to the turnover position and max(Bj)≤max(Ai)*C, the transport component transports one of the battery boxes with max(Ai) to the battery swapping vehicle.

[0028] In a second aspect, the present invention discloses a battery swapping system, wherein the battery swapping system is applied to any of the battery swapping methods described in the first aspect, and the battery swapping system comprises:

[0029] A charging assembly, comprising a frame unit and a charging base; the charging base is disposed within the space enclosed by the frame unit.

[0030] A transport assembly includes a large trolley guide rail, a first small trolley guide rail, a second small trolley guide rail, a small trolley body, and a gripping part. The large trolley guide rail is slidably connected to the end of the frame unit away from the charging base. One end of the first small trolley guide rail is slidably connected to the large trolley guide rail, and the other end extends away from the charging base. The first small trolley guide rail moves along the length direction of the frame unit. The second small trolley guide rail is slidably connected to the first small trolley guide rail. The first small trolley guide rail moves along the width direction of the frame unit. The small trolley body is slidably connected to the second small trolley guide rail. The small trolley body moves along the width direction of the frame unit. The gripping part is driven to move the small trolley body along the height direction of the frame unit.

[0031] A battery box, which is detachably connected to and electrically connected to the charging dock; the conveying assembly is used to assemble and disassemble the battery box from the charging dock.

[0032] A power transmission vehicle, comprising a power transmission vehicle body and a base; the base is connected to the power transmission vehicle body; the base is detachably connected to the battery box; and the handling assembly is used to detach and install the battery box from the base.

[0033] A battery swapping vehicle includes a battery swapping body and a discharge base; the battery swapping body is connected to the discharge base; the discharge base is detachably connected to and electrically connected to the battery box; the handling assembly is used to detach and install the battery box and the discharge base.

[0034] P + Q + M - 1 = N; where P is the number of charging docks, Q is the number of bases, M is the number of discharging docks, and N is the number of battery boxes.

[0035] In some embodiments, the top of the charging dock is lower than the top of the base in the power supply area; the top of the charging dock is lower than the top of the discharge dock in the battery swapping area.

[0036] To address the problem of low power transmission efficiency of power transmission vehicles, this invention has the following advantages:

[0037] Based on the condition that max(Bj) ≥ max(Ai)*C in the battery swapping information, when the maximum charge of the battery box on the power delivery vehicle reaches more than 85% of the maximum charge of the battery box on the battery swapping station, the transport component prioritizes transferring the battery box with max(Bj) charge from the power delivery vehicle to the battery swapping vehicle. By establishing a dynamic matching mechanism between battery box charge and turnover location, the power delivery vehicle's battery box can be directly called upon to perform supplementary battery swapping operations while the battery swapping vehicle is unloading the battery box with insufficient charge to the turnover location. This allows the power delivery vehicle to release the transported battery box without waiting for the battery swapping station to complete the charging of the existing batteries, shortening the temporary storage period of the battery box within the battery swapping station and reducing the single operation time of the power delivery vehicle. Ultimately, this achieves the technical effect that the power delivery vehicle can immediately perform a new transportation task after delivering the battery box. Attached Figure Description

[0047] In this embodiment, in the traditional battery swapping process, when the battery swapping vehicle 04 enters the battery swapping area, the charge Ai of the battery box 05 in the charging component 01 and the charge Bj of the battery box 05 on the power delivery vehicle 03 do not form a dynamic correlation matching mechanism. In the prior art, when the transport component 02 performs battery box 05 replacement, it usually prioritizes calling the already charged battery box 05 in the charging component 01 for replenishment, while the battery box 05 carried by the power delivery vehicle 03 in the power delivery area is only used as a spare inventory. This operation mode causes the power delivery vehicle 03 to have to wait for a long time before it can unload the battery box 05 it carries, resulting in a long single operation time for the power delivery vehicle 03 and low power delivery efficiency. This embodiment discloses a battery swapping method, such as Figure 1 As shown, the battery swapping method may include steps S01 to S03, and each step is described in detail below:

[0048] like Figure 4 As shown, the battery swapping system may include a charging component 01, a transport component 02, a battery box 05, a power supply vehicle 03, and a battery swapping vehicle 04. The charging assembly 01 may include a frame unit 11 and a charging base 12; the charging base 12 is disposed within the space enclosed by the frame unit 11; the transport assembly 02 may include a large trolley guide rail 21, a first small trolley guide rail 23, a second small trolley guide rail 24, a small trolley body 26, and a gripping part 29; the large trolley guide rail 21 may be slidably connected to the end of the frame unit 11 away from the charging base 12; one end of the first small trolley guide rail 23 may be slidably connected to the large trolley guide rail 21, and the other end may extend away from the charging base 12; the first small trolley guide rail 23 may move along the length direction of the frame unit 11; the second small trolley guide rail 24 may be slidably connected to the first small trolley guide rail 23; the first small trolley guide rail 23 may move along the width direction of the frame unit 11; the small trolley body 26 may be slidably connected to the second small trolley guide rail 24; the small trolley body 26 may move along the width direction of the frame unit 11; the gripping part 29 may be drivenly connected to the small trolley body 26; the gripping part 29... The vehicle body 26 can be driven 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 base 12; the handling component 02 can be used to detach and install the battery box 05 and the charging base 12; the power supply vehicle 03 may include a power supply vehicle body 31 and a base 32; the base 32 is connected to the power supply vehicle body 31; the base 32 is detachably connected to the battery box 05; the handling component 02 can be used to detach and install the battery box 05 and the base 32; the battery swapping vehicle 04 may include a battery swapping vehicle body 41 and a discharge base 42; the battery swapping vehicle body 41 is connected to the discharge base 42; the discharge base 42 is detachably connected to and electrically connected to the battery box 05; the handling component 02 is used to detach and install the battery box 05 and the discharge base 42; when the battery swapping vehicle 04 moves to the battery swapping area, the handling component 02 can transport the battery box 05 on the charging component 01 or the power supply vehicle 03 to the battery swapping vehicle 04 to complete the battery swapping of the battery swapping vehicle 04.

[0049] In step S10, based on the battery swapping vehicle 04 entering the battery swapping area, the battery swapping information of the battery swapping system can be obtained; the battery swapping area can be the area projected towards the charging base 12 when the trolley body 26 of the transport component 02 moves to one side of the width direction of the frame unit 11, such as... Figure 3 The area shown is the projection area of ​​the bottom of the battery swapping vehicle 04. The battery swapping information may include the battery charge Ai of the battery box 05 inside the charging assembly 01, the turnover position of the battery box 05, and the battery charge Bj of the battery box 05 on the power delivery vehicle 03 within the power delivery area; i and j are both natural numbers. For example, when there are 8 battery boxes 05 inside the charging assembly 01, Ai can be A1~A8, representing the battery charge of each of the eight battery boxes 05 on the charging assembly 01. When there are 8 battery boxes 05 on the power delivery vehicle 03, Bj can be B1~B8, representing the battery charge of each of the eight battery boxes 05 on the power delivery vehicle 03. By acquiring the battery charge Ai of the battery box 05 inside the charging assembly 01 and the battery charge Bj of the battery box 05 on the power delivery vehicle 03, a dynamic correlation matching mechanism can be formed between the battery charge Ai of the battery box 05 inside the charging assembly 01 and the battery charge Bj of the battery box 05 on the power delivery vehicle 03, facilitating the subsequent battery box 05 replacement operation performed by the transport assembly 02. The power supply area can be the area located on the side of the frame unit 11 away from the power swapping area in the width direction and adjacent to the frame unit 11, such as... Figure 3 The area projected onto the bottom of the power transmission vehicle 03 shown.

[0050] In step S20, such as Figure 2 As shown, based on the battery swapping vehicle 04 completing its positioning in the battery swapping area and obtaining its turnover location, the transport component 02 can transport the low-battery battery box 05 of the battery swapping vehicle 04 to the turnover location; wherein, the turnover location can be an idle charging seat 12 that is not connected to the battery box 05 or an idle base 32 that is not connected to the battery box 05.

[0051] In step S30, based on the condition that the battery box 05 with low power is moved to the turnover position and max(Bj)≥max(Ai)*C, the handling component 02 can move one battery box 05 with max(Bj) power to the battery swapping vehicle 04; where C≥0.85. When the maximum power of the battery box 05 on the power supply vehicle 03 reaches 85% or more of the maximum power of the battery box 05 on the battery swapping station, the handling component 02 prioritizes transferring the battery box 05 with max(Bj) power from 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 used first, thereby reducing the dwell time of the power supply vehicle 03 in the battery swapping area, allowing the power supply vehicle 03 to transport the next batch of battery boxes 05, increasing the number of round trips 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, and S03 are executed sequentially.

[0052] In this embodiment, step S20 may include steps S21 to S22, and each step is described in detail below:

[0053] In step S21, based on the battery swapping vehicle 04 being positioned in the battery swapping area and its turnover position being within the charging assembly 01, the transport assembly 02 can move the low-battery box 05 of the battery swapping vehicle 04 to the turnover position via the battery swapping door 114. The frame unit 11 may 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 base 12 can be disposed within the space enclosed by the housing 112 and the battery swapping door 114, and is spaced apart from the support beam 111. The battery swapping door 114 can be disposed on the side of the housing 112 closer to the battery swapping area. The bottom of the battery swapping door 114 is higher than or flush with the top of the battery box 05 inside the charging base 12, thereby avoiding 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 includes a first state and a second state. The first state includes a space enclosed by the housing 112 and the battery swapping door 114, which communicates with the external space of the frame unit 11 through the battery swapping door 114. The second state includes a space separated from the external space of the frame unit 11 by the space enclosed by the housing 112 and the battery swapping door 114. In some 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 within the battery swapping area. This method allows for fewer sensors to be used while accurately detecting the position of the battery box 05 on the battery swapping vehicle 04 within the battery swapping area, thus saving costs.

[0054] In step S22, the low-battery box 05 of the battery swapping vehicle 04 is moved above the turnover position via the battery swapping gate 114 by the handling component 02. The handling component 02 can then lower the low-battery box 05 into the turnover position, thus transferring the low-battery box 05 from the battery swapping vehicle 04 to the turnover position, facilitating the subsequent placement of the max(Bj) battery box 05 onto the battery swapping vehicle 04 by the handling component 02. Steps S10, S21, S22, and S30 are executed sequentially.

[0055] In this embodiment, step S20 may include steps S23 to S24, and each step is described in detail below:

[0056] In step S23, based on the fact that the battery swapping vehicle 04 has been positioned in the battery swapping area and its turnover position is on the power supply vehicle 03, the transport component 02 can move the low-battery box 05 of the battery swapping vehicle 04 sequentially through the battery swapping door 114 and the power supply door 113 to above the charging seat 12 of the idle charging component 01; the frame unit 11 can also connect to the power supply door 113, and the housing 112 can be movably connected to the power supply door 113. Figure 6 As shown, the power supply gate 113 can be located on the side of the housing 112 away from the battery swapping area. The bottom of the power supply gate 113 is higher than or flush with the top of the battery box 05 inside the charging base 12. The power supply gate 113 includes a third state and a fourth state. The third state includes the space enclosed by the housing 112 and the power supply gate 113 communicating with the external space of the frame unit 11 through the power supply gate 113. The fourth state includes the space enclosed by the housing 112 and the power supply gate 113 being separated from the external space of the frame unit 11. In some embodiments, the width of the battery swapping gate 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 within the battery swapping area. This method allows for fewer sensors to be used while accurately detecting the position of the battery box 05 on the battery swapping vehicle 04 within the battery swapping area, saving costs. The width of the power supply gate 113 can be k times the width of the battery swapping gate 114, where k is the number of mounting seats on the power supply vehicle. Additionally, k sensors can be connected to the frame unit 11, with each sensor detecting the position of the battery box 05 on the power supply vehicle 03 within a power supply area. The frame unit 11 can protect the charging base 12 and the battery box 05 within it. If the width of the power supply gate 113 is too small, the power supply vehicle 03 needs to frequently move to ensure that the transport assembly 02 can move the battery box 05 from the power supply vehicle 03 to the power supply gate 113. Increasing the width of the battery swapping gate improves the battery swapping efficiency of the battery swapping vehicle 04.

[0057] In step S24, the low-battery box 05 of the battery swapping vehicle 04 is moved sequentially through the battery swapping door 114 and the power supply door 113 to above the idle charging seat 12 by the transport component 02. The transport component 02 can then lower the low-battery box 05 into the turnover position. Steps S10, S23, S24, and S30 are executed sequentially.

[0058] In this embodiment, the battery swapping method may further include steps S41 to S42, each of which is described in detail below:

[0059] In step S41, the number of battery swapping vehicles 04 in the waiting area is obtained;

[0060] In step S42, based on the number of battery swapping vehicles 04 in the waiting area being greater than or equal to a set value, an instruction is issued for the next power supply vehicle 03 to proceed to the power supply area. The set value can be equal to the number of bases 32 on the power supply vehicle 03, or it can be 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 respond ahead of time, ensuring the normal operation of the battery swapping station. Simultaneously, prioritizing the use of the battery boxes 05 on the power supply vehicle 03 (i.e., battery boxes 05 with lower charging costs within the charging point) can save costs. Steps S41 and S42 can be performed sequentially at any time.

[0061] In this embodiment, the battery swapping method may further include steps S43 to S44, each of which is described in detail below:

[0062] In step S43, a battery box 05 of max(Bj) is transported to the battery swapping vehicle 04 based on the transport component 02, and battery swapping information is obtained; wherein, the battery swapping information also includes the number of battery swapping vehicles 04 in the waiting area;

[0063] In step S44, based on the fact that there is no battery swapping vehicle 04 in the waiting area, max(Bj)-min(Ai)≥X>0 and the turnover position is located on the power supply vehicle 03, the transport component 02 can move a battery box 05 of min(Ai) to the turnover position; where X can be the difference in charge between the smallest battery in the charging component 01 and the largest battery on the power supply vehicle; when there is no battery swapping vehicle 04 in the waiting area, in order to ensure that the dwell time of the power supply vehicle 03 is short, the multi-battery box 05 on the power supply vehicle 03 can be moved to the power supply vehicle 03, thereby reducing the dwell time of the power supply vehicle 03 in the battery swapping area, so that the power supply vehicle 03 can transport the next batch of battery boxes 05 again, increasing the number of round trips from the charging point to the battery swapping area per unit time, and improving the power supply efficiency of the power supply vehicle 03.

[0064] In step S45, the transport component 02 moves a minimum (Ai) battery box 05 to the turnover position, and then moves a maximum (Bj) battery box 05 into the charging component 01. At this time, the turnover position is on the power delivery vehicle 03. When the subsequent battery swapping vehicle 04 arrives at the battery swapping area, the low-power battery box 05 on the battery swapping vehicle 04 can be directly moved to the base 32 on the power delivery vehicle 03. To ensure a short dwell time for the power delivery vehicle 03, the battery boxes 05 on the power delivery vehicle 03 can be moved to the charging component 01, increasing the number of round trips from the charging point to the battery swapping area per unit time and improving the power delivery efficiency of the power delivery vehicle 03. Steps S10, S20, S30, S43, S44, and S45 are executed sequentially.

[0065] In this embodiment, the battery swapping method may further include step S46:

[0066] In step S46, based on the fact that there is no battery swapping vehicle 04 in the waiting area, 0 < max(Bj) - min(Ai) < Z, and the turnover position is located within the charging component 01, the transport component 02 moves a max(Bj) battery box 05 to the turnover position. When the difference in charge between the minimum charge battery in the charging component 01 and the maximum charge battery on the power delivery vehicle is less than a set value, the battery box 05 on the battery swapping vehicle 04 can be moved to the turnover position on the charging component 01. At this time, the turnover position is on the power delivery vehicle 03. When the subsequent battery swapping vehicle 04 arrives at the battery swapping area, the low-charge battery box 05 on the battery swapping vehicle 04 can be directly moved to the base 32 on the power delivery vehicle 03. This shortens the dwell time of the power delivery vehicle 03, increases the number of round trips from the charging point to the battery swapping area per unit time, and improves the power delivery efficiency of the power delivery vehicle 03. Steps S10, S20, S30, S43, and S46 are executed sequentially.

[0067] In this embodiment, the battery swapping method may further include step S47:

[0068] In step S47, based on min(Ai) - max(Bj) ≥ 0 and the turnover position being within the charging component 01, a departure command can be issued to the power supply vehicle 03 within the power supply area. When the maximum capacity battery box 05 on the power supply vehicle 03 is less than the minimum capacity battery box 05 within the charging component 01, the power supply vehicle 03 can leave the battery swapping area, allowing the battery swapping station to improve the working efficiency of the power supply vehicle 03 while ensuring normal battery swapping for the vehicle. In other embodiments, when the power supply vehicle 03 leaves the power supply area, the next power supply vehicle 03 can enter the power supply area. Steps S10, S20, S30, S43, and S47 are executed sequentially.
