It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] Glossary: Fixed-route logistics: a form of transportation organization that uses a fixed fleet of vehicles based on shipping points to specifically complete fixed freight tasks.

[0021] New energy commercial vehicles: refers to commercial vehicles that use non-traditional fuels or energy, such as commercial vehicles that use electricity. New energy commercial vehicles include: pure electric commercial vehicles, plug-in hybrid commercial vehicles, fuel cell commercial vehicles, extended-range electric commercial vehicles, etc.

[0022] The energy replenishment planning of traditional fuel commercial vehicles can provide reference for new energy commercial vehicles (such as new energy heavy trucks) to a certain extent, but due to the significant differences in technology, infrastructure, and energy replenishment methods of new energy commercial vehicles, it cannot be fully applied. New energy commercial vehicles need to introduce new methods in energy replenishment planning. The differences between energy replenishment planning of new energy commercial vehicles and conventional fuel commercial vehicles are mainly reflected in the following aspects: 1. Differences in energy use.

[0023] Traditional fuel commercial vehicles are powered by fuel, so fuel consumption needs to be monitored during transportation routes. New energy commercial vehicles are powered by battery power, so battery power consumption needs to be monitored during transportation routes.

[0024] 2. Differences in energy replenishment methods.

[0025] New energy commercial vehicles use charging stations to recharge their energy, which takes a long time, especially in the case of slow charging, which may take several hours. Therefore, the energy replenishment plan must take the charging time into consideration.

[0026] In addition, new energy commercial vehicles can also recharge by replacing batteries at battery swap stations, which can replace batteries in a few minutes, reducing waiting time for charging. For logistics companies with fixed routes, considering the layout of battery swap stations can significantly improve operational efficiency.

[0027] 3. Differences in energy replenishment facilities.

[0028] Traditional fuel commercial vehicles recharge at gas stations, while new energy commercial vehicles recharge at charging stations or battery swap stations. And charging stations or battery swap stations are not as popular as traditional gas stations. Therefore, when planning the recharging of new energy commercial vehicles, special attention should be paid to the distribution of recharging facilities along the way. And because the recharging time of new energy commercial vehicles is long, the recharging facilities are easily occupied for a long time. Therefore, when planning the recharging of new energy commercial vehicles, special attention should be paid to the queuing and use of recharging facilities along the way.

[0029] In view of the fact that the energy replenishment planning of traditional fuel commercial vehicles cannot be fully applicable to the energy replenishment planning of new energy commercial vehicles, the present invention analyzes the differences between the energy replenishment planning of new energy commercial vehicles and that of traditional fuel commercial vehicles, thereby proposing a commercial vehicle energy replenishment method to achieve intelligent and efficient charging and energy replenishment of new energy commercial vehicles and ensure that new energy commercial vehicles can successfully complete transportation tasks.

[0030] Reference Figure 1 , showing a flow chart of an embodiment of a method for planning energy replenishment for a new energy commercial vehicle for fixed-route logistics provided by the present invention, the commercial vehicle includes a battery, and the method includes: S101, obtaining target information; the target information includes the cruising range information of the commercial vehicle, the transportation mission information of the commercial vehicle and the charging facility information. The commercial vehicle in this embodiment may be a new energy commercial vehicle, especially an electric-driven new energy commercial vehicle.

[0031] A vehicle collector can be installed on a commercial vehicle, and the vehicle collector can include a power sensor, a vehicle speed sensor, a GPS module, etc. The vehicle collector can be used to obtain commercial vehicle information, such as the location of the commercial vehicle, the driving speed, the remaining battery power, the battery power consumption per kilometer, etc. The commercial vehicle's endurance information can be obtained through the obtained commercial vehicle information, and the endurance information can include the endurance mileage, which can be the ratio of the remaining battery power to the battery power consumption per kilometer.

[0032] The transportation task information of a commercial vehicle may include the starting point of the transportation task, the end point of the transportation task, the total distance of the transportation task, the completed distance of the transportation task, the remaining distance of the transportation task and the estimated completion time of the transportation task, etc.

[0033] Energy replenishment facilities may include charging stations and / or battery swap stations. Charging stations are used to charge the batteries of commercial vehicles, and battery swap stations are used to replace the batteries of commercial vehicles. Energy replenishment facilities may also be other facilities that can provide electrical energy for commercial vehicles.

[0034] The charging facility information may include the location of each charging facility within the preset range of the commercial vehicle, the first distance of each charging facility from the commercial vehicle, the availability of each charging facility, and the queue usage of each charging facility. The availability of the charging facility includes available and unavailable; the queue usage of the charging facility may include the charging facility not queuing, the charging facility is queuing, and the estimated queuing time.

[0035] S102: Determine, based on the target information, whether the commercial vehicle is recharging at a recharging facility during the transportation mission. Based on the cruising range information of the commercial vehicle, the transportation mission information of the commercial vehicle and the charging facility information, it can be determined whether the commercial vehicle needs to be recharged at the charging facility during the transportation mission. For example, if the current cruising range of the commercial vehicle is sufficient to complete the transportation mission of the commercial vehicle, then the commercial vehicle does not need to be charged and recharged before completing the transportation mission; if the current cruising range of the commercial vehicle is not sufficient to complete the transportation mission of the commercial vehicle, a target charging facility can be selected to charge and recharge the commercial vehicle. The target charging facility can be the charging facility closest to the commercial vehicle.

[0036] S103, when it is determined that the commercial vehicle is recharging at the recharging facility during the transportation mission, determine the target recharging method; the target recharging method includes: charging the battery at a first charging rate, charging the battery at a second charging rate, and replacing the battery; wherein the first charging rate is greater than the second charging rate.

[0037] When it is determined that a commercial vehicle needs to be recharged at a recharging facility during a transportation mission, the target recharging method for the commercial vehicle can be determined based on at least one of the urgency of the transportation mission, the loading and unloading arrangements in the transportation mission, the time when the commercial vehicle arrives at the recharging facility, the energy supply of the recharging facility, the charging of the recharging facility, and the use of the recharging facility. The target recharging method may include: charging the battery at a first charging rate, i.e., fast charging, which may refer to a charging method with a charging power greater than 22kW; charging the battery at a second charging rate, i.e., slow charging, which may refer to a charging method with a charging power less than or equal to 22kW; and replacing the battery of the commercial vehicle.

[0038] For example, when the task is more urgent, you can choose fast charging or directly replace the commercial vehicle battery; when the commercial vehicle arrives at the charging facility at night, you can choose slow charging, which gives the driver sufficient rest time and prolongs the battery life; when the commercial vehicle is loading and unloading goods, you can choose slow charging, fast charging or battery replacement according to the loading and unloading time, so as to reduce the impact of charging on transportation efficiency; when the energy supply of the charging facility is tight, battery replacement or fast charging is given priority; when the transportation task is not urgent, cheaper charging methods can be given priority; when the charging facility is in peak usage time, battery replacement or fast charging is given priority; when the charging facility is in non-peak usage time, slow charging can be given priority, and so on.

[0039] The present invention combines the cruising range information of commercial vehicles, the transportation mission information of commercial vehicles, the energy replenishment facility information and various energy replenishment methods of new energy commercial vehicles to dynamically plan the charging and energy replenishment schemes of new energy commercial vehicles in transportation missions, thereby realizing intelligent and efficient charging and energy replenishment of new energy commercial vehicles and ensuring that new energy commercial vehicles can successfully complete transportation missions.

[0040] In addition, taking into full consideration the different times required for various recharging methods for new energy commercial vehicles, combining the urgency of the transportation task, the loading and unloading arrangements in the transportation task, the time for the commercial vehicle to arrive at the recharging facility, the energy supply of the recharging facility, the charging situation of the recharging facility, and at least one of the usage of the recharging facility, determining the target recharging method for the commercial vehicle from various recharging methods can extend the battery life, ensure transportation efficiency, and save recharging costs.

[0041] In one embodiment, the cruising range information of the commercial vehicle may include the cruising range, the transportation task information may include the remaining distance of the transportation task, and the energy replenishment facility information may include the first distance between each energy replenishment facility and the commercial vehicle. Figure 2 , shows a schematic diagram of a flow chart of determining whether to replenish energy provided by the present invention, the method comprising: S201, determining a target energy charging facility and a target first distance between the target energy charging facility and the commercial vehicle according to the first distance between each energy charging facility and the commercial vehicle.

[0042] The target energy replenishment facility may be an energy replenishment facility with the shortest first distance.

[0043] S202, determining whether the cruising range is less than the sum of the remaining distance of the transport task and the first target distance.

[0044] S203: If the cruising range is less than the sum of the remaining distance of the transport task and the target first distance, it is determined that the commercial vehicle is refueled at the target refueling facility during the transport task.

[0045] S204: If the cruising range is greater than or equal to the sum of the remaining distance of the transport task and the first distance, it is determined that the commercial vehicle does not recharge at the target recharging facility during the transport task.

[0046] The following formula can be used to determine whether it is necessary to recharge energy at the target recharge facility: , ; in, Indicates the cruising range, that is, the mileage that can be continued (unit: km); Indicates the remaining distance of the transport task (unit: km); Indicates the target first distance between the current target charging facility and the commercial vehicle (unit: km); Indicates the remaining power of the battery (unit: kWh); It represents the first power consumption per kilometer of the battery (unit: kWh / km). The first power consumption per kilometer of the battery can be obtained according to the power consumption of the battery when the commercial vehicle is driving in the historical time.

[0047] when When the commercial vehicle needs to be recharged at the target recharging facility during the transportation mission; When determining whether a commercial vehicle does not need to be refueled at the target refueling facility during the transportation mission.

[0048] In this embodiment, considering that the target energy replenishment facility may not be on the planned route of the transportation task, it may be necessary to take a detour to reach the target energy replenishment facility. Therefore, the remaining distance of the transportation task and the first target distance are considered together. When determining the commercial vehicle's transportation mission, it is determined that the commercial vehicle needs to be recharged at the target recharging facility.

[0049] In one embodiment, the charging facility information also includes the available status of each charging facility and the queuing time of each charging facility: then S201 may specifically include: determining the target charging facility according to the first distance between each charging facility and the commercial vehicle, the available status of each charging facility, and the queuing time of each charging facility.

[0050] The charging facility with the shortest first distance can be preferentially selected as the target charging facility. When the charging facility with the shortest first distance is unavailable, the charging facility with the second shortest first distance, which is available and whose queuing time is within the preset queuing time threshold, can be selected as the target charging facility.

[0051] In one embodiment, S101 may specifically include: obtaining the remaining power of the battery and a first power consumption per kilometer; determining the congestion situation on the target road section; the target road section includes at least one of the remaining sections of the transportation task and the section between the commercial vehicle and the target energy replenishment facility; correcting the first power consumption per kilometer according to the congestion situation to obtain a second power consumption per kilometer; and obtaining the cruising range of the commercial vehicle based on the remaining power and the second power consumption per kilometer.

[0052] The congestion on the target road section will also affect the power consumption of the commercial vehicle. The power consumption will be significantly different under acceleration, deceleration and idling conditions in the congested road section. Under congested road conditions, the commercial vehicle will consume less power when driving at a low speed. Therefore, in this embodiment, the congestion of the target road section will be evaluated, and the first power consumption per kilometer of the commercial vehicle will be corrected according to the congestion of the target road section to obtain the estimated second power consumption per kilometer of the commercial vehicle on the target road section, so that the cruising range can be obtained more accurately.

[0053] Reference Figure 3 , shows a schematic diagram of a target road section congestion determination process provided by the present invention, the method comprising: S301, obtaining the length of the target road section, the average vehicle speed on the target road section when it is not congested, the average acceleration on the target road section when it is not congested, the number of vehicles on the current target road section, the speed of each vehicle, the acceleration of each vehicle and the first congestion index obtained by monitoring the target road section through a third-party traffic data platform.

[0055] The number of vehicles on the target road section, the travel speed of each vehicle, the acceleration of each vehicle and the first congestion index are all currently acquired real-time data.

[0056] S302: Determine a second congestion index of the target road section according to the average vehicle speed when the target road section is not congested and the driving speed of each vehicle on the current target road section.

[0062] S305: Determine a target congestion index of the target road section according to the first congestion index, the second congestion index, the traffic density, and the vehicle acceleration fluctuation index.

[0063] The target congestion index can be calculated using the following formula: , in, represents the target congestion index; represents the first congestion index; f represents a function, which is used to fit the relationship between the first congestion index, traffic density, the second congestion index, the vehicle acceleration fluctuation index and the congestion situation of the target road section, so as to obtain .

[0064] In one embodiment, the target congestion index is less than or equal to 1 and greater than or equal to 0, and the target congestion index represents the degree of congestion of the target road section. When the target congestion index is equal to 1, it indicates no congestion, and when the target congestion index is equal to 0, it indicates severe congestion. Then, the first power consumption per kilometer is corrected according to the congestion situation, and the step of obtaining the second power consumption per kilometer may specifically include: taking the product of the target congestion index and the first power consumption per kilometer as the second power consumption per kilometer.

[0065] The value can be between 0 and 1, indicating the degree of traffic smoothness of the target road section. : means smooth flow, The closer it is to 0, the more severe the congestion.

[0069] Different recharging methods have different recharging times. Therefore, the recharging time for the commercial vehicle to reach the target recharging facility can be calculated based on the final target recharging method.

[0070] The remaining distance of the transport task can be calculated using the following formula:
