Description

Technical Field

[0001] This invention relates to the field of battery swapping technology, and in particular to a method, apparatus and equipment for swapping batteries in electric engineering machinery. Background Technology

[0002] With the increasing number of electric construction machinery, battery swapping technology has emerged to address the issues of short battery life and long charging times. This technology allows electric construction machinery to have its batteries replaced when it is out of power or about to run out of power.

[0003] Since most electric construction machinery has tracked wheels, it is difficult to travel on roads. If electric construction machinery needs to go to a home electric vehicle battery swapping station for battery swapping, it needs to be done within a specific time period or requires a rescue vehicle. In addition, there are few battery swapping stations in areas where electric construction machinery can travel. Furthermore, battery swapping for electric construction machinery requires going through various routes, which makes battery swapping very difficult. Therefore, as the number of electric construction machinery in the battery swapping station increases, the station will gradually become congested, and may even cause traffic congestion at the station's entrance and exit. In addition, electric construction machinery that runs out of power before it can be moved to the battery swapping station needs to be towed to the station for battery swapping, which increases the waiting time for users. Summary of the Invention

[0004] The main objective of this invention is to provide a battery replacement method, apparatus, and equipment for electric construction machinery, aiming to solve the technical problem in the prior art where there is congestion within battery swapping stations, and electric construction machinery that runs out of power before reaching a battery swapping station needs to be towed to the station by a rescue vehicle for battery swapping, resulting in increased waiting time for users.

[0005] To achieve the above objectives, the present invention provides a battery replacement method for electric construction machinery, the battery replacement method for electric construction machinery comprising:

[0006] Obtain the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped;

[0007] Real-time acquisition of congestion information and remaining fuel level of the mobile battery swapping vehicle along the initial route;

[0008] The initial route is updated based on the congestion situation and the remaining fuel information to obtain the circuit breaker route;

[0009] The battery swapping line is sent to the mobile battery swapping vehicle, which then swaps the battery for the machine to be swapped based on the battery swapping line.

[0010] Optionally, the step of updating the initial route based on the congestion situation and the remaining fuel information to obtain the circuit-swapping route includes:

[0017] If the battery swapping task of the battery swapping vehicle is not completed and the remaining fuel of the battery swapping vehicle is sufficient to reach the final location, then the working route of the battery swapping vehicle is changed.

[0018] Optionally, after the step of querying the battery swapping task of the battery swapping vehicle, the method further includes:

[0020] Based on the historical driving data, the operation process of the missing motor to be replaced is simulated, the consumption of the remaining power is detected, and the maximum driving distance of the missing motor to be replaced is determined.

[0021] Based on the current location, find the nearest battery swapping station to the omitted battery swapping machine and determine the swapping distance;

[0022] If the limit driving distance is greater than or equal to the battery swapping distance, then a battery swapping navigation is generated for the missed battery swapping machine to go to the battery swapping station, and the battery swapping navigation is sent to the missed battery swapping machine.

[0023] Optionally, the step of filtering the extreme routes of the mobile battery swapping vehicle from the new routes based on the remaining fuel information includes:

[0024] Based on the remaining fuel information, simulation data was generated simulating the operation of the mobile battery swapping vehicle on the new route.

[0025] Based on the simulation data, the extreme route of the mobile battery swapping vehicle at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted or depleted is obtained.

[0026] Optionally, the step of obtaining the extreme route of the mobile battery swapping vehicle at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted, based on the simulation data, includes:

[0027] Based on the simulation data, the meeting points between the battery-swapping machines and the mobile battery-swapping vehicle, as well as the gas stations, are marked on the new route;

[0028] Determine the refueling distance from the meeting point to the nearest gas station, and predict the remaining fuel amount of the mobile battery swapping vehicle at each meeting point;

[0029] Based on the refueling distance and the remaining fuel, the new route is modified to obtain the extreme route for the mobile battery swapping vehicle to be located at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted or depleted.

[0030] Optionally, the step of obtaining the initial route for the mobile battery swapping vehicle to swap batteries for the machinery to be swapped includes:

[0031] Obtain equipment data for the machinery to be swapped;

[0032] Based on the device data, predict the trajectory points of the machine to be swapped;

[0033] The meeting point between the mobile battery swapping vehicle and the machine to be swapped is predicted based on the trajectory points;

[0034] Based on the meeting point, the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped is planned.

[0035] Optionally, the step of planning the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped based on the meeting point includes:

[0036] Determine the travel distance of the mobile battery swapping vehicle from its current location to each of the meeting points;

[0037] Based on the travel distance, the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped is planned.

[0038] Furthermore, to achieve the above objectives, the present invention also provides a battery replacement device for electric construction machinery, the battery replacement device for electric construction machinery comprising:

[0039] The first acquisition module is used to acquire the initial route for the mobile battery swapping vehicle to swap batteries for the machinery to be swapped;

[0040] The second acquisition module is used to acquire the congestion situation of the initial route and the remaining fuel information of the mobile battery swapping vehicle in real time.

[0041] The update module is used to update the initial route based on the congestion situation and the remaining fuel information to obtain the circuit breaker route;

[0042] The sending module is used to send the battery swapping line to the mobile battery swapping vehicle, so that the mobile battery swapping vehicle can swap batteries for the mechanical device to be swapped based on the battery swapping line.

[0043] Furthermore, to achieve the above objectives, the present invention also proposes a battery replacement device for electric construction machinery, the device comprising: a memory, a processor, and a battery replacement program for electric construction machinery stored in the memory and executable on the processor, the battery replacement program for electric construction machinery being configured to implement the steps of the battery replacement method for electric construction machinery as described above.

[0044] Furthermore, to achieve the above objectives, the present invention also proposes a storage medium storing a battery replacement program for an electric construction machinery, wherein when the battery replacement program for the electric construction machinery is executed by a processor, the steps of the battery replacement method for the electric construction machinery as described above are implemented.

[0045] This invention provides a battery replacement method, apparatus, and equipment for electric construction machinery. Compared to existing technologies where battery swapping stations are congested and electric construction machinery that runs out of power before reaching a station needs to be towed there, resulting in increased waiting time for users, this invention obtains an initial route for a mobile battery swapping vehicle to swap batteries for the machinery to be swapped; it acquires real-time information on congestion along the initial route and the remaining fuel level of the mobile battery swapping vehicle; it updates the initial route based on the congestion and remaining fuel level information to obtain a battery swapping route; and it sends the battery swapping route to the mobile battery swapping vehicle, enabling the mobile battery swapping vehicle to swap batteries for the machinery to be swapped based on the battery swapping route. In this invention, the initial route of the mobile battery swapping vehicle is first obtained, and the vehicle is then used to swap batteries for the devices waiting to be swapped. The congestion status of the initial route and the remaining fuel level of the mobile battery swapping vehicle are obtained in real time. The initial route is updated based on the remaining fuel level and congestion status to obtain a new swapping route. This avoids the mobile battery swapping vehicle being blocked, which increases the swapping time, and also prevents the vehicle from running out of fuel during its journey, requiring assistance from other vehicles. In other words, by comprehensively planning the route based on the mobile battery swapping vehicle's own situation and road conditions, a swapping route is obtained to avoid time-consuming situations. This prevents devices waiting to be swapped from waiting at battery swapping stations and also prevents devices from running out of power during their journey, requiring a rescue vehicle to go to the battery swapping station. Therefore, it reduces the waiting time for users of devices waiting to be swapped. Attached Figure Description

[0061] This invention provides a battery replacement method for electric construction machinery, referring to... Figure 2 , Figure 2 This is a schematic flowchart of the first embodiment of a battery replacement method for electric engineering machinery according to the present invention.

[0062] It should be noted that the execution subject of this embodiment can be the battery replacement device of the electric construction machinery. The battery replacement device of the electric construction machinery can be an electronic device such as a personal computer, smartphone, or tablet computer, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the battery replacement device of the electric construction machinery is used as an example to illustrate the battery replacement method of the electric construction machinery of the present invention.

[0063] In this embodiment, the battery replacement method for the electric construction machinery includes:

[0064] Step S10: Obtain the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped.

[0065] It should be noted that the mobile battery swapping vehicle can be a vehicle carrying batteries and equipped with a hoisting device, used to travel to the location of the device to be swapped for battery replacement. In order to reduce the waiting time of the operator of the device, the device to be swapped may be in motion when the device whose battery needs to be swapped is identified, and the mobile battery swapping vehicle may carry multiple batteries. In order for the mobile battery swapping vehicle to work efficiently, it is necessary to obtain the initial route of the mobile battery swapping vehicle for swapping the battery of the device.

[0066] In practice, before obtaining the initial route, the current equipment information of the equipment to be swapped and the remaining fuel information of the mobile battery swapping vehicle can be obtained first. The initial route of the mobile battery swapping vehicle can be planned based on the current vehicle information and the remaining fuel information of the mobile battery swapping vehicle to avoid the situation where the mobile battery swapping vehicle has insufficient remaining fuel during operation.

[0067] Step S20: Obtain real-time information on congestion along the initial route and the remaining fuel level of the mobile battery swapping vehicle.

[0068] It should be noted that, since road conditions change in real time, in order for the mobile battery swapping vehicle to meet the machine to be swapped according to the route, it is necessary to obtain the initial route congestion situation and the remaining fuel information of the mobile battery swapping vehicle in real time, so as to avoid the mobile battery swapping vehicle having insufficient remaining fuel to meet the machine to be swapped.

[0069] It should be noted that, during the operation of the battery swapping machine, the initial route planning also predicts the movement trajectory of the machine based on its average speed and road conditions. The point where the mobile battery swapping vehicle and the machine theoretically arrive simultaneously is marked on the trajectory and designated as the meeting point on the initial route. This meeting point is then fed back to the machine so that its operator knows the location of the mobile battery swapping vehicle. This prevents the operator from being distracted while searching for the vehicle. Therefore, feeding back the meeting point allows the operator to focus on driving the machine to the meeting point, avoiding distraction.

[0070] In practice, the congestion status of the initial route is obtained in real time to avoid the mobile battery swapping vehicle encountering road congestion while following the initial route. This allows the battery swapping equipment to wait at the meeting point. In other words, by obtaining the congestion status of the initial route in real time, the route can be adjusted to allow the mobile battery swapping vehicle to avoid congested sections. Due to the route adjustment, the fuel consumption of the mobile battery swapping vehicle to the meeting point will also change. In order to ensure that the mobile battery swapping vehicle can arrive at the meeting point on time, it is also necessary to obtain the remaining fuel of the mobile battery swapping vehicle in real time to avoid the mobile battery swapping vehicle changing routes to refuel at gas stations due to insufficient fuel. Therefore, it is also necessary to avoid the operator of the battery swapping equipment having to wait at the meeting point.

[0071] Step S30: Update the initial route based on the congestion situation and the remaining fuel information to obtain the circuit breaker route.

[0072] It should be noted that the initial route of the mobile battery swapping vehicle is changed according to the congestion situation to avoid the mobile battery swapping vehicle taking longer to reach the meeting point due to road congestion, thereby increasing the waiting time for operators of the waiting battery swapping machines and reducing the waiting time for users of the waiting battery swapping machines.

[0073] It should be noted that when the remaining fuel of the mobile battery swapping vehicle is insufficient to reach the next meeting point for the machine to be swapped, the system checks whether there is a gas station in the direction the mobile battery swapping vehicle is traveling on the initial route, and whether the mobile battery swapping vehicle can reach the gas station. If it can reach the gas station, the initial route does not need to be adjusted. If there is no gas station or the gas station cannot be reached, the system marks the nearest gas station to the mobile battery swapping vehicle and marks it as the next destination for the mobile battery swapping vehicle. The system also promptly matches other mobile battery swapping vehicles to the machine to be swapped, so as to avoid the operator waiting at the meeting point and reduce the waiting time for the user (operator) of the machine to be swapped.

[0074] In practice, the driving route of the mobile battery swapping vehicle is adjusted in real time based on the congestion situation and remaining fuel information. The swapping route is obtained and sent to the mobile battery swapping vehicle in a timely manner to avoid the operator's waiting time for battery swapping increasing due to the mobile battery swapping vehicle being blocked or having to change routes to refuel.

[0075] Step S40: The battery swapping line is sent to the mobile battery swapping vehicle, so that the mobile battery swapping vehicle can swap batteries for the machine to be swapped based on the battery swapping line.

[0076] In practice, the battery swapping route is sent to the mobile battery swapping vehicle, which then travels along the route and proceeds in a planned manner to the meeting point for battery swapping, thus avoiding long waiting times for the vehicles waiting to be swapped.

[0077] This embodiment provides a battery replacement method for electric construction machinery. Compared with the existing technology where battery swapping stations are congested and electric construction machinery that runs out of power before reaching a station needs to be towed there for battery swapping, resulting in increased waiting time for users, this invention obtains the initial route for a mobile battery swapping vehicle to swap batteries for the machinery to be swapped; it acquires the congestion status of the initial route and the remaining fuel information of the mobile battery swapping vehicle in real time; it updates the initial route based on the congestion status and the remaining fuel information to obtain a battery swapping route; and it sends the battery swapping route to the mobile battery swapping vehicle, enabling the mobile battery swapping vehicle to swap batteries for the machinery to be swapped based on the battery swapping route. In this invention, the initial route of the mobile battery swapping vehicle is first obtained, and the vehicle is then used to swap batteries for the devices waiting to be swapped. The congestion status of the initial route and the remaining fuel level of the mobile battery swapping vehicle are obtained in real time. The initial route is updated based on the remaining fuel level and congestion status to obtain a new swapping route. This avoids the mobile battery swapping vehicle being blocked, which increases the swapping time, and also prevents the vehicle from running out of fuel during its journey, requiring assistance from other vehicles. In other words, by comprehensively planning the route based on the mobile battery swapping vehicle's own situation and road conditions, a swapping route is obtained to avoid time-consuming situations. This prevents devices waiting to be swapped from waiting at battery swapping stations and also prevents devices from running out of power during their journey, requiring a rescue vehicle to go to the battery swapping station. Therefore, it reduces the waiting time for users of devices waiting to be swapped.

[0078] refer to Figure 3 , Figure 3 This is a schematic flowchart of the second embodiment of the battery replacement method for electric engineering machinery of the present invention.

[0079] Based on the above embodiments, in this embodiment, in order for the mobile battery swapping vehicle to swap batteries for machines located far from charging stations and to plan routes, step S30 includes:

[0080] Step S01: Based on the congestion situation, plan a new, currently uncongested route from the initial route;

[0081] Step S02: Based on the remaining fuel information, select the extreme routes of the mobile battery swapping vehicle from the new routes;

[0082] Step S03: Update the initial route with the extreme route to obtain the circuit switching route.

[0083] It should be noted that the system can obtain the congested sections of the initial route in real time and query new, uncongested routes from the map of those sections. Furthermore, the analysis of congestion on the initial route can be done in segments. That is, the system can first analyze the road conditions from the mobile battery swapping vehicle to the next battery swapping machine to avoid congestion on that segment of the route.

[0084] It should be noted that, in order for the mobile battery swapping vehicle to reach the next meeting point of the device waiting for battery swapping along the new route, the furthest meeting point that the mobile battery swapping vehicle can reach before running out of fuel can be selected from the new route. The extreme route is one where the mobile battery swapping vehicle has enough fuel to reach the gas station before reaching the furthest meeting point. This allows the mobile battery swapping vehicle to travel to a location far from the battery swapping station without increasing the user's waiting time for battery swapping, so as to swap batteries for devices that are far from the battery swapping station.

[0085] In practice, the route between the mobile battery swapping vehicle and the next battery swapping machine is replanned based on the congestion situation to obtain a new route that is not currently congested. Since the fuel consumption of the mobile battery swapping vehicle to serve the next battery swapping machine will also change after the route is updated, in order to ensure that the mobile battery swapping vehicle can serve the battery swapping machine that is as far away from the battery swapping station as possible, and to ensure that the mobile battery swapping vehicle has enough fuel to go to the gas station, the extreme route of the mobile battery swapping vehicle can be selected from the new route based on the remaining fuel, and the initial route is updated with the extreme route to obtain the battery swapping route.

[0086] Optionally, after the initial route update, some devices that were originally served by the mobile battery swapping vehicle may no longer be on the swapping route. To ensure that these missed devices can be swapped in a timely manner, after step S03, the following steps are also included:

[0087] Step S04: Mark the omitted battery swapping machines that were deleted from the initial route after the initial route update;

[0088] Step S05: Determine the battery swapping vehicle closest to the omitted battery swapping machine, excluding the mobile battery swapping vehicle;

[0089] Step S06: Query the battery swapping task of the battery swapping vehicle. If the battery swapping task is not full and the remaining fuel of the battery swapping vehicle is sufficient for the battery swapping vehicle to reach the final location, then change the working route of the battery swapping vehicle.

[0090] It should be noted that after the initial route is updated, any missing battery swapping machines removed from the initial route are marked, and the nearest battery swapping vehicle is dispatched. If the battery swapping vehicle is not fully booked and its remaining fuel is sufficient to reach its final destination, the vehicle's route is changed so that it can serve the missing battery swapping machines. This is to prevent the missing battery swapping machines from running out of power on their way to the battery swapping station and to avoid increasing the waiting time for battery swapping.

[0091] Optionally, after the step of querying the battery swapping task of the battery swapping vehicle, the method further includes:

[0092] Step S061: If the battery swapping vehicle task is full, obtain the remaining battery power, historical driving data and current location of the missing battery swapping machine.

[0093] Step S062: Based on the historical driving data, simulate the operation process of the missing motor to be replaced, detect the consumption of the remaining power, and the maximum driving distance of the missing motor to be replaced.

[0094] Step S063: Based on the current location, query the nearest battery swapping station to the missed battery swapping machine and determine the battery swapping distance;

[0095] Step S064: Determine whether the maximum driving distance is greater than or equal to the battery swapping distance. If so, generate a battery swapping navigation for the missed battery swapping machine to go to the battery swapping station, and send the battery swapping navigation to the missed battery swapping machine.

[0096] It should be noted that if the missing battery swapping machine is close to the battery swapping station and the remaining power of the missing battery swapping machine is sufficient for the machine to travel to the station, then a battery swapping vehicle need not be assigned to the missing battery swapping machine. This is to reasonably allocate the workload between the battery swapping vehicles and the battery swapping station, so that more batteries swapping machines can be swapped within a certain period of time.

[0097] It should be noted that after determining that the missing battery swapping machine can go to the swapping station, a battery swapping navigation is planned based on the remaining power of the machine and the road conditions from the current location to the swapping station. This navigation is then sent to the missing machine so that it can travel to the swapping station with the most energy-efficient approach, thus conserving more power to deal with any unexpected situations on the way.

[0098] In the specific implementation, the missing battery swapping machines removed from the swapping line due to the initial route update are marked. The nearest battery swapping vehicle to the missing battery swapping machine is determined. If the battery swapping vehicle has not completed its swapping tasks, that is, if the battery swapping vehicle still has batteries remaining after serving the missing battery swapping machines on the corresponding work route, and the battery swapping vehicle can return to the original work route and travel to the final location after serving the missing battery swapping machines, then the battery swapping vehicle will serve the missing battery swapping machines. If the battery swapping vehicle has no batteries remaining after removing the batteries needed, or if adding the missing battery swapping machines to the battery swapping vehicle's tasks would affect the original tasks of the battery swapping vehicle, then other battery swapping vehicles are searched.

[0099] Furthermore, the step of selecting the most extreme routes for the mobile battery swapping vehicle from the new routes based on the remaining fuel information includes:

[0100] Step S021: Based on the remaining fuel information, simulate the mobile battery swapping vehicle operating on the new route using simulation data;

[0101] Step S022: Based on the simulation data, obtain the extreme route of the mobile battery swapping vehicle at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted or depleted.

[0102] It should be noted that the fuel consumption information, such as the driving speed and gear of the mobile battery swapping vehicle, is first determined. Based on the fuel consumption information and the remaining fuel information, the driving process of the mobile battery swapping vehicle on the new service route is simulated to obtain simulation data. Then, based on the simulation data, the extreme route that the mobile battery swapping vehicle can travel to the gas station to complete all battery swapping tasks before the remaining fuel is exhausted is obtained from the new route. This avoids the mobile battery swapping vehicle having to detour to the gas station to refuel when performing tasks, and thus avoids the mobile battery swapping vehicle increasing the waiting time for users to swap batteries due to refueling.

[0103] Further, the step of obtaining the extreme route of the mobile battery swapping vehicle at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted, based on the simulation data, includes:

[0104] Step S0221: Based on the simulation data, mark the meeting point between the battery-swapping machine and the mobile battery-swapping vehicle, as well as the gas station, on the new route;

[0105] Step S0222: Determine the refueling distance from the meeting point to the nearest gas station, and predict the remaining fuel amount of the mobile battery swapping vehicle at each meeting point;

[0106] Step S0223: Based on the refueling distance and the remaining fuel, modify the new route to obtain the extreme route of the mobile battery swapping vehicle at the gas station before the remaining fuel of the mobile battery swapping vehicle is exhausted or depleted.

[0107] In practice, since the battery-swapping machine is in motion, the travel time to the machine changes after the mobile battery-swapping vehicle's route changes. Therefore, the meeting point between the machine and the mobile battery-swapping vehicle also changes. After obtaining the new route, it is necessary to redetermine the meeting point between the machine and the mobile battery-swapping vehicle based on simulation data, mark the meeting point and the gas stations near the new route, determine the refueling distance between the meeting point and the nearest gas station, and then predict the remaining fuel of the mobile battery-swapping vehicle at each meeting point. If the remaining fuel is insufficient for the mobile battery-swapping vehicle to travel to the next meeting point, the battery-swapping task of the mobile battery-swapping vehicle will end, and the vehicle will proceed to the nearest gas station.

[0108] For example, based on simulation data, the remaining fuel is determined to be 10% at the sixth meeting point, 3% at the seventh meeting point, and 0% at the eighth meeting point. Since the point where the fuel runs out is on the route from the seventh to the eighth meeting point, to ensure the mobile battery swapping vehicle doesn't need to detour to a gas station and thus reduce user waiting time, the nearest gas station to the seventh meeting point can be identified. If the gas station is on the route to the eighth meeting point, the vehicle can go to the gas station first, as this avoids a detour and minimizes user waiting time. If a detour is required to reach the gas station from the seventh meeting point, the battery swapping machine corresponding to the eighth meeting point can be removed from the new route and marked as a missed machine. If the 3% remaining fuel is insufficient for the mobile battery swapping vehicle to travel from the seventh meeting point to the gas station, the battery swapping task between the seventh and eighth meeting points can be completed at the sixth meeting point, and the vehicle can then proceed to the gas station from the sixth meeting point.

[0109] refer to Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the battery replacement method for electric engineering machinery of the present invention.

[0110] Based on the above embodiments, in this embodiment, the step of obtaining the initial route for the mobile battery swapping vehicle to swap batteries for the mechanical device to be swapped includes:

[0111] Step S1: Obtain equipment data for the machinery to be swapped;

[0112] Step S2: Based on the device data, predict the trajectory points of the machine to be swapped;

[0113] Step S3: Predict the meeting point between the mobile battery swapping vehicle and the machine to be swapped based on the trajectory points;

[0114] Step S4: Based on the meeting point, plan the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped.

[0115] It should be noted that data such as the state of charge, gear, energy consumption, ambient temperature, battery temperature, battery health status, and location of the power battery of the device to be swapped are obtained. Based on this data, the driving trajectory of the device to be swapped is predicted, and the theoretical meeting point between the devices is determined according to the trajectory, so as to shorten or eliminate the waiting time for users of the device to be swapped.

[0116] It should be noted that since the driving direction and route of each battery swapping vehicle are different, and the remaining power can support different durations, in order to ensure that the mobile battery swapping vehicle can work efficiently and to prevent the battery swapping vehicle from running out of power on the road, the initial route of the mobile battery swapping vehicle can be planned based on the remaining power and the meeting point.

[0117] In practice, the meeting points of the devices with less remaining power should be placed ahead of the initial route as much as possible. If there is a device with more remaining power between the meeting points of two devices with less remaining power, in order to avoid the mobile battery swapping vehicle traveling back and forth, the meeting point of the device with more remaining power can be marked on the initial route between the meeting points of the two devices with less remaining power.

[0118] For example, the remaining charge of device A to be swapped is 22%, and the corresponding meeting point is A; the remaining charge of device B to be swapped is 30%, and the corresponding meeting point is B; the remaining charge of device C to be swapped is 18%, and the corresponding meeting point is C; the remaining charge of device D to be swapped is 25%, and the corresponding meeting point is D. The distribution of each meeting point is as follows: Figure 5 As shown, since the battery swapping machine D is closest to the battery swapping station, the initial route is planned so that the battery swapping vehicle first goes to the meeting point D. Although the meeting point B is closest to the meeting point D, the remaining power of the battery swapping machine C is less than that of the battery swapping machine B. Therefore, the battery swapping task of the battery swapping machine C can be arranged before that of the battery swapping machine B. By prioritizing tasks with less remaining power, after the battery swapping task of the battery swapping machine C is completed, the battery swapping task of the battery swapping machine A needs to be completed. However, the journey from the meeting point C to the meeting point A will pass through the meeting point B. Therefore, the battery swapping task of the battery swapping machine B can be arranged before that of the battery swapping machine A. That is, the initial route is battery swapping station - meeting point D - meeting point C - meeting point B - meeting point A.

[0119] Furthermore, the step of planning the initial route for the mobile battery swapping vehicle to swap batteries for the machines to be swapped based on the meeting point includes:

[0120] Step S401: Determine the travel distance of the mobile battery swapping vehicle from its current location to each of the meeting points;

[0121] Step S402: Based on the travel distance, plan the initial route for the mobile battery swapping vehicle to swap batteries for the machinery to be swapped.

[0122] In the specific implementation, the travel distance of the mobile battery swapping vehicle from its current location to each meeting point is determined. Based on the travel distance, the initial route is planned from near to far, and priority is given to planning the battery swapping machines with less remaining power. This is to avoid the battery swapping machines with less remaining power not being able to support the mobile battery swapping vehicle to reach the corresponding meeting point, so as to reduce the waiting time for all users of the battery swapping machines.
