Electric vehicles provide electrical energy through batteries, and as the vehicle runs continuously consuming electricity, the situation of battery power shortage is prone to occur. In the related art, there are mainly the following methods for charging electric vehicles.

One way is that managers carry batteries, find electric vehicles in a state of power shortage, and replace the batteries with new ones, or managers bring charging devices to charge the vehicles. Another way is for managers to collect power-deficient vehicles on the road and transport them to designated locations for battery replacement or charging.

Detailed ways

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

Fig. 1 is a flow chart of a method for sharing electricity according to an exemplary embodiment, the method can be applied to vehicles, such as electric bicycles, unmanned electric distribution vehicles, unmanned electric vehicles, new energy vehicles, and hybrid vehicles Wait. For example, the power sharing method can be applied to the field of delivery of goods by unmanned electric delivery vehicles, such as the scenario of using unmanned electric delivery vehicles for express delivery and takeaway delivery. Under certain circumstances, electric power sharing can be carried out between unmanned electric distribution vehicles. As shown in FIG. 1, the method may include S101 and S102.

In S101, the current electric quantity of each vehicle in the initial vehicle set is obtained.

The initial vehicle set may include a plurality of vehicles including the own vehicle, and the distance between each vehicle and at least one other vehicle in the initial vehicle set is less than a preset distance threshold. Among them, a distance sensor may be installed on the vehicle, such as Near-Field Electromagnetic Ranging (NFER), and the vehicle can detect a vehicle whose distance to itself is less than a preset distance threshold through the distance sensor, and the preset distance threshold value It can be pre-calibrated, and the present disclosure does not specifically limit its value. A short-range communication module, such as a Bluetooth module, a near-field communication module, etc., can also be installed on the vehicle, and information can be transmitted between the vehicles through the short-range communication module.

FIG. 2 is a schematic diagram illustrating an initial vehicle set according to an exemplary embodiment. As shown in FIG. 2 , the initial vehicle set may include a vehicle 201 , a vehicle 202 , a vehicle 203 , a vehicle 204 , and a vehicle 205 . It should be noted that FIG. 2 shows that the initial vehicle set includes five vehicles, which is only an example, and the present disclosure does not specifically limit the number of vehicles in the initial vehicle set.

Taking the vehicle 201 as the vehicle as an example, the process of constructing the initial vehicle set by the vehicle 201 is described. For example, if the vehicle 201 can detect that the vehicles whose distances to itself are less than the preset distance threshold include the vehicle 202 and the vehicle 203 , it can be determined that the initial vehicle set includes at least the own vehicle 201 , and the vehicles 202 and 203 . The vehicle 203 can detect that the distance between the vehicle 203 and the vehicle 203 is less than the preset distance threshold. Vehicle 201, so that vehicle 201 may determine that vehicle 204 may also be included in the initial set of vehicles. Vehicles that the vehicle 204 can detect and the distance between the vehicle 204 and the vehicle 204 is less than the preset distance threshold include the vehicle 205 and the vehicle 203. Vehicle 203, and vehicle 203 may then forward this information to vehicle 201, so that vehicle 201 may determine that vehicle 205 may also be included in the initial vehicle set. In this way, each vehicle can detect a vehicle whose distance to itself is less than the preset distance threshold, and send the vehicle's information and the distance between itself and the vehicle to adjacent vehicles, and through the information transmission between vehicles, Vehicle 201 may determine that vehicles 201 to 205 are included in the initial vehicle set.

The process of constructing the initial vehicle set is described above by taking the vehicle 201 as the vehicle as an example, and each vehicle can construct the initial vehicle set through this process. For example, for the vehicle 203, the vehicle 203 can detect vehicles whose distance to itself is less than the preset distance threshold, including the vehicle 201 and the vehicle 204, the vehicle 201 can send the information of the vehicle 202 to the vehicle 203, and the vehicle 204 can send the vehicle 205 The information of the vehicle 203 is sent to the vehicle 203, so that the vehicle 203 can determine that the vehicle 201 to the vehicle 205 are included in the initial vehicle set. The process of building the initial vehicle ensemble for other vehicles is similar.

It is worth noting that the power sharing method provided by the present disclosure can be applied to the process of vehicle parking. After the vehicle detects a vehicle whose distance to itself is less than a preset distance threshold, the information of the vehicle can be synchronized to other vehicles. For a vehicle, if the vehicle does not receive information about a new vehicle within a preset period of time, it can indicate that there is no new vehicle parked nearby, and the construction process of the initial vehicle set can be ended. Since information can be transmitted between vehicles through short-range communication, the initial vehicle sets constructed by vehicles 201 to 205 are the same through information exchange and synchronization between vehicles.

Wherein, the own vehicle can obtain its own current power and the respective current powers of other vehicles in the initial vehicle set except the own vehicle, so as to obtain the current power of each vehicle in the initial vehicle set. For example, the current power level may be expressed in the form of a percentage, for example, the current power level of the vehicle is 90%.

As shown in FIG. 2 , taking the vehicle 201 as the own vehicle as an example, the process of obtaining the current electric quantity of each other vehicle except the vehicle 201 in the initial vehicle set by the vehicle 201 is described. Wherein, both the vehicle 202 and the vehicle 203 can send their own current power to the vehicle 201 through short-range communication, the vehicle 204 can send their own current power to the vehicle 203, and then the vehicle 203 can send the current power of the vehicle 204 to the vehicle. 201 , the vehicle 205 can send its own current power to the vehicle 204 , and the vehicle 204 can send the current power of the vehicle 205 to the vehicle 203 , which is then forwarded to the vehicle 201 by the vehicle 203 . In this way, the vehicle 201 can acquire the current power levels of each of the vehicles 202 to 205 . In this way, information is transmitted and synchronized between vehicles by means of short-range communication, and each vehicle can obtain the respective current power levels of other vehicles in the initial vehicle set except itself.

In S102, when the own vehicle is the vehicle with the largest current electric power in the initial vehicle set, the electric power sharing is performed among the vehicles in the target vehicle set through the control of the own vehicle. The target vehicle set is a subset of the initial vehicle set.

The target vehicle set includes all or part of the vehicles in the initial vehicle set, and the target vehicle set may include at least two vehicles in the initial vehicle set, and the at least two vehicles include the own vehicle.

According to the current power of each vehicle in the initial vehicle set, the vehicle can determine whether the vehicle is the vehicle with the most current power. If the vehicle is the vehicle with the current maximum power, it can control the power sharing among the vehicles in the target vehicle set. . Due to the power sharing between the vehicles in the control target vehicle set, it is necessary to perform certain calculations to determine the appropriate power sharing method, such as which vehicles are used as the charging party and which vehicles are the charged parties, and the calculation process needs to consume a certain amount of power. Therefore, the vehicle with the largest current electric quantity in the initial vehicle set, that is, the relatively sufficient electric quantity, is selected to control the electric power sharing among the vehicles in the target vehicle set.

The power sharing between vehicles may be a process in which a vehicle with a high current power charges a vehicle with a low current power, so as to achieve power balance among the vehicles. There is no specific limitation on the charging method in this disclosure, and a wireless charging method or a wired charging method can be used. When the wired charging method is adopted, manual charging is not required, and an automatic charging robot arm can be installed on the vehicle. When charging is required, the charging robot arm can automatically charge Extend for charging operation.

As shown in FIG. 2 , taking the vehicle 201 as the vehicle as an example, the vehicle 201 determines that it is the vehicle with the largest current power in the initial vehicle set, and can control the power sharing among the vehicles in the target vehicle set, where the target vehicle set is A subset of the initial vehicle set, for example, the target vehicle set includes vehicles 201 to 204 . If the vehicle determines that it is not the vehicle with the current maximum power, it can wait for the power sharing information synchronized by the vehicle with the current maximum power in the initial set, and perform power sharing according to the received power sharing information. For example, if the vehicle 202 determines that it is not the vehicle with the most current power, it can wait for the power sharing information sent by the vehicle 201 .

Through the above solution, when the vehicle is the vehicle with the largest current electricity in the initial vehicle set, the vehicle controls the vehicle in the target vehicle set to share electricity, wherein the target vehicle set is a subset of the initial vehicle set. By adopting the power sharing method of the present disclosure, there is no need for the server to control the vehicle, and the remote communication between the vehicle and the server is not required, which effectively avoids the problem of unstable remote communication between the server and the vehicle. The information can be synchronized to the vehicles in the target vehicle set through short-range communication between vehicles, so as to realize the power sharing between vehicles. Through the short-range communication, the information transmission is relatively more reliable. In addition, for vehicles that were previously unavailable due to insufficient power, after the power sharing between vehicles, the power of each vehicle can be relatively balanced, the number of vehicles with unusable power can be reduced, and the number of vehicles with available power can be increased. The phenomenon that the vehicle cannot be used. In addition, because vehicles with low power can be temporarily charged by vehicles with high power, the frequency of battery replacement or charging by managers is reduced at the same time, saving manpower. Perform overall charging to improve charging efficiency.

In the present disclosure, in the case that the vehicle is the vehicle with the largest current power in the initial vehicle set, before the vehicle controls the power sharing among the vehicles in the target vehicle set, the vehicle can determine the target vehicle set in the following manner:

According to the current power of each vehicle in the initial vehicle set, determine the current total power of the initial vehicle set; determine the ratio of the current total power to the number of vehicles in the initial vehicle set; when the ratio is less than or equal to the preset power threshold, and the number of vehicles In the case of greater than 2, the vehicle with the smallest current power is removed from the initial vehicle set to obtain the updated initial vehicle set; based on the initial vehicle set after each update, the ratio is iteratively calculated until the ratio is greater than Preset power threshold; take the initial vehicle set obtained by the last update as the target vehicle set.

The preset electric power threshold may be determined according to the minimum electric power required for the normal running of the vehicle, for example, the preset electric power threshold may be set to be 1.5 times the minimum electric power required for the normal running of the vehicle. If the current power of the vehicle is less than or equal to the minimum power required for the normal driving of the vehicle, the vehicle is in a state of power shortage and is currently unavailable. If the current power of the vehicle is less than or equal to the preset power threshold, it can indicate that the current power of the vehicle is low. The mileage is shorter.

For example, the current electric power of the vehicle can be expressed in the form of a percentage, and the sum of the current electric power of each vehicle in the initial vehicle set can be taken as the current total electric power of the initial vehicle set, and the current total electric power is, for example, M%. The number of vehicles in is N, then the ratio of M to N can be determined.

If the ratio is less than or equal to the preset electric power threshold, then after all the vehicles in the initial vehicle set share electric power, the electric power of each vehicle is low. In the present disclosure, when the ratio is less than or equal to the preset electric power threshold and the number of vehicles in the initial vehicle set is greater than 2, the vehicle with the current minimum electric power can be removed from the initial vehicle set to obtain an updated initial vehicle set . Among them, if the vehicle with the smallest current power participates in the power sharing, other vehicles will charge the vehicle with the smallest power, which will reduce the power of other vehicles. Therefore, in order to avoid affecting the normal use of other vehicles, it is not necessary to carry out all the vehicles in the initial vehicle set. The vehicle with the smallest current power is removed from the vehicle set, the updated initial vehicle set is obtained, and the steps of determining the current total power of the initial vehicle set according to the current power of each vehicle in the initial vehicle set are re-executed. to the step of determining the ratio of the current total charge to the number of vehicles in the initial vehicle set.

Based on the initial vehicle set after each update, iteratively calculate the ratio of the current total power to the number of vehicles in the currently obtained initial vehicle set until the ratio is greater than the preset power threshold, and use the last updated initial vehicle set as A collection of target vehicles.

If the ratio of the current total power to the number of vehicles obtained in the initial vehicle set is greater than the preset power threshold, after the vehicles in the initial vehicle set share power, the power of each vehicle is greater than the preset power threshold and can be used normally. Therefore, the initial vehicle set obtained by the last update can be determined as the target vehicle set, and the vehicle in the target vehicle set can be controlled by the vehicle to share electricity among the vehicles in the target vehicle set.

For example, the current vehicle set is the initial vehicle set shown in FIG. 2 , the own vehicle 201 is the vehicle with the largest current power, and the vehicle with the smallest current power is the vehicle 205. If the vehicle 201 determines that the current total power of the vehicles 201 to 205 is the same as If the ratio of the number of vehicles to 5 is less than or equal to the preset electric power threshold, the vehicle 205 can be removed from the initial vehicle set, and the obtained updated initial vehicle set includes vehicles 201 to 204, and re-executes according to each of the initial vehicle sets. The current electric quantity of a vehicle, from the steps of determining the current total electric quantity of the initial vehicle set to the step of determining the ratio of the current total electric quantity to the number of vehicles in the initial vehicle set. If the vehicle 201 determines that the ratio of the current total power of the vehicles 201 to 204 to the number of vehicles 4 is greater than the preset power threshold, the set composed of the vehicles 201 to 204 can be determined as the target vehicle set, and the target vehicle set is shown in FIG. 3 . shown, including vehicles 201 to 204 . It should be noted that the target vehicle set shown in FIG. 3 is only exemplary, for example, the target vehicle set may include all vehicles in the initial vehicle set shown in FIG. 2 , and may also include vehicles 201 to 203 .

In addition, when the ratio of the current total power of the initial vehicle set obtained at present to the number of vehicles is less than or equal to the preset power threshold, and the number of vehicles is less than or equal to 2, the vehicle can send the vehicle power shortage prompt information, for example, The vehicle can send the power shortage prompt information to the server or the terminal used by the administrator.

Wherein, if the ratio is less than or equal to the preset power threshold, and the number of vehicles is less than or equal to 2, even if power sharing between two vehicles in the current vehicle set is performed, the vehicle is still unavailable or the driving range is low, and, The current power of the vehicles that have been eliminated from the initial vehicle set constructed first is also low, that is, the current power of the vehicles in the initial vehicle set constructed first is low, and they are all in a power-deficient state. Charge the vehicle or replace the power source. As the vehicle with the largest current power in the initial vehicle set, it can send the vehicle power shortage prompt information to the server or the terminal used by the administrator. The vehicle power shortage prompt information can include the identification information, location information, current power level of each vehicle in the initial vehicle set Wait. If the vehicle power shortage prompt information is sent to the server, after receiving the vehicle power shortage prompt information, the server can forward the information to the terminal used by the management personnel, so that the management personnel can charge the power shortage vehicle in time, so as to ensure The vehicle can be used normally.

Through the above solution, in the case where the ratio of the current total electric power of the initial vehicle set to the number of vehicles is less than or equal to the preset electric power threshold, in order to avoid the situation that the electric power of each vehicle is low after the electric power sharing is performed, the initial vehicle may not be executed. Power sharing among all vehicles in the collection. If the number of vehicles in the initial vehicle set is greater than 2, the vehicle with the smallest current power can be deleted from the initial vehicle set to prevent the vehicle with the smallest power from lowering the power of other vehicles, so as to obtain an updated initial vehicle set. Based on the initial vehicle set after each update, the ratio is iteratively calculated until the ratio is greater than the preset electric power threshold, and the initial vehicle set obtained by the last update can be used as the target vehicle set. After sharing, the power of each vehicle is greater than the preset power threshold, more vehicles can be used normally, and the vehicle utilization rate is high, thereby ensuring the effectiveness of power sharing.

In the present disclosure, in the case that the vehicle is the vehicle with the largest current power in the initial vehicle set, the vehicle in the target vehicle set can be used to control the power sharing. FIG. 4 is a diagram according to an exemplary embodiment. A flow chart of a method for controlling power sharing among vehicles in a target vehicle set, as shown in FIG. 4 , the method may include S401 and S402.

In S401, target power sharing information corresponding to the target vehicle set is determined.

The power sharing information may include first indication information for indicating the vehicle in the target vehicle set as the charging party, second indication information for indicating the vehicle in the target vehicle set as the charging party, and the charging direction needs to be directed to the charging party. The charging capacity information of the charging party. Taking the vehicle 201 and the vehicle 202 in the target vehicle set shown in FIG. 3 as an example, for example, the power sharing information is used to indicate that the vehicle 201 is the charging party, the vehicle 202 is the charging party, and the charging power information that the vehicle 201 needs to charge the vehicle 202. is x%.

In an optional implementation manner, an exemplary implementation of this step S401 may be: according to one or more influence factors, determine the income information corresponding to a plurality of preset power sharing information respectively, and the income information is used to represent the power sharing. the overall revenue of the target vehicle set; determine the optimal power sharing information from a variety of preset power sharing information, wherein the optimal power sharing information corresponds to the optimal revenue information; determine the optimal power sharing information as the target power sharing information .

Wherein, the vehicles in the target vehicle set may have a variety of possible power sharing modes for power sharing, and the preset power sharing information may be the information on the planned power sharing mode. The income information corresponding to the preset electric power sharing information may be used to represent the overall income of the target vehicle set after the vehicles in the target vehicle set share electric power according to the preset electric power sharing information. The influence factor may include: the increment of the number of vehicles with available electric power, the total charging distance, and the sum of information on the electric power difference between the vehicles in the target vehicle set after electric power sharing is performed.

Wherein, a vehicle with available power may refer to a vehicle whose power is higher than the minimum power required for normal running of the vehicle, and a vehicle with an unavailable vehicle may refer to a vehicle whose power is lower than the minimum power. For example, the initial vehicle set includes 3 vehicles with unavailable power, the target vehicle set includes all vehicles in the initial vehicle set, and after the power sharing between vehicles, all vehicles are available with power, then the increment of the number of vehicles with available power is 3. The total charging distance may include the total distance between the charging party and the charged party. For example, the vehicle 201 charges the vehicle 202 and the vehicle 203 charges the vehicle 204. The total charging distance may include the distance between the vehicle 201 and the vehicle 202 and the vehicle 203 The sum of the distances to the vehicle 204 . The sum of electric quantity difference information may refer to the sum of absolute values of electric quantity difference information between every two vehicles in the target vehicle set after electric quantity sharing is performed.

The income information corresponding to the preset power sharing information may be determined according to one or more influence factors, and several exemplary implementations for determining the income information are described below.

In one embodiment, the income information may be determined according to the increment of the number of vehicles with available electric power, and the increment of the number of vehicles with available electric power is the largest, that is, the income information is optimal.

In another embodiment, the income information may be determined according to the sum of the electric quantity difference information between the vehicles in the target vehicle set after electric quantity sharing, and the sum of the electric quantity difference information is the smallest, that is, the income information is optimal.

In yet another embodiment, the revenue information can be determined according to the increment of the number of vehicles with available electric power, the total charging distance, and the sum of the electric power difference information between the vehicles in the target vehicle set after the electric power sharing is performed. The following formula (1) determines the income information F, and when F is the largest, it is the optimal income information:

F=a*delta_vehicle-b*dist_total-c*delta_power_diff (1)

Among them, a represents the weight of the increment of the number of vehicles with available electricity, b represents the weight of the total charging distance, c represents the weight of the sum of the difference information of electricity, delta_vehicle represents the increment of the number of vehicles with available electricity, dist_total represents the total charging distance, delta_power_diff represents the sum of the power difference information, and the values of a, b, and c can be preset and are all greater than 0.

In the present disclosure, the optimal power sharing information can be determined from a variety of preset power sharing information, the optimal power sharing information corresponds to the optimal revenue information, and the optimal power sharing information is used as the target power sharing information, so that the optimal power sharing information is used as the target power sharing information. Vehicles in the target vehicle set share power according to the target power sharing information, which can achieve the optimal overall revenue of the target vehicle set.

In S402, the target power sharing information is synchronized to other vehicles in the target vehicle set except the vehicle, so that the vehicles in the target vehicle set perform power sharing according to the target power sharing information.

Wherein, synchronizing the target power sharing information to other vehicles in the target vehicle set except the vehicle may refer to distributing the target power sharing information to other vehicles through information transmission between vehicles.

As shown in FIG. 3 , taking the vehicle 201 as the own vehicle and being used to control the vehicles in the target vehicle set to share electricity as an example, the vehicle 201 can determine the target electricity sharing information corresponding to the target vehicle set.
