Technical Field

[0001] The present invention relates to the technical field of charging operation, and in particular to a mobile charging management method and system. Background Art

[0002] Mobile charging technology is to receive the user's charging service initiation order through the background cloud, and assign a mobile charging vehicle to execute the charging service for each charging service initiation order until the mobile charging vehicle is monitored to have completed the charging service initiation order. A mobile charging vehicle is a device that charges electric vehicles at a designated location after receiving the user's charging order in the background. When the next charging service initiation order to be executed is assigned to it in the background, it needs to move from its current location to the location of the vehicle to be charged in the charging service initiation order to be executed, and then charge the vehicle to be charged in the charging service initiation order to be executed.

[0003] However, due to the rapid development and large-scale implementation of electric vehicles, the number of charging service orders in a unit area has increased sharply. Under the premise of investing a limited number of mobile charging vehicles, how to reasonably allocate mobile charging vehicles for a large number of charging service orders received to reduce the distance traveled by mobile charging vehicles to the charged vehicles, thereby improving order processing efficiency and charging service quality, is a major technical difficulty.

[0067] In this embodiment, the mobile charging service is a charging service provided by a mobile charging vehicle to a vehicle that initiates an order for the charging service, that is, a service of moving to the vehicle that initiates the order for the charging service and charging the vehicle.

[0068] In this embodiment, the complete coverage area refers to all areas where the mobile charging management system can provide services.

[0069] In this embodiment, the sub-region is a smaller region included in the complete coverage region, and the specific division method can be manually set according to management requirements. For example, the region can be divided according to administrative units.

[0070] In this embodiment, the charging service initiation order is an order initiated by a vehicle that needs to be charged to the backend of the mobile charging management system to request a mobile charging vehicle to charge it.

[0071] In this embodiment, all charging service initiation orders from within the complete coverage area are all charging service initiation orders for vehicles that need to be charged within the complete coverage area.

[0072] In this embodiment, the mobile charging vehicle that performs the service is a mobile charging vehicle that provides charging services to the vehicle that needs to be charged corresponding to the charging service initiating order.

[0073] The beneficial effects of the above technology are: based on the latest received charging service initiation orders from all charging service initiation orders within the complete coverage area, the current location and service status of all mobile charging vehicles, as well as the real-time traffic flow of all sub-areas, historical traffic flow data, and historical mobile charging service records, all charging service initiation orders received from the complete coverage area are reasonably allocated to mobile charging vehicles for service execution, which reduces the distance traveled by mobile charging vehicles to the charged vehicles, thereby improving order processing efficiency and charging service quality.

[0078] In this embodiment, the inflow vehicle flow is the number of electric vehicles that enter the corresponding area during the period from the last statistical moment to the current statistical moment.

[0079] In this embodiment, the outflow traffic volume is the number of electric vehicles that have left the corresponding area during the period from the last statistical moment to the current statistical moment.

[0085] In this embodiment, the historical period is a period before the current moment.

[0086] In this embodiment, the statistical moment is the moment of obtaining the real-time maintained vehicle flow, and the time intervals between all adjacent statistical moments are equal.

[0087] In this embodiment, the order initiation time is the time when the mobile charging management system receives the mobile charging service order.

If so, the predicted remaining service time and predicted remaining power of the charging service being performed by the corresponding mobile charging vehicle are regarded as the service status of the corresponding mobile charging vehicle. Otherwise, the current remaining power of the corresponding mobile charging vehicle is regarded as the service status of the corresponding mobile charging vehicle.

[0093] In this embodiment, determining whether each mobile charging vehicle of the mobile charging service is currently performing service means determining whether each mobile charging vehicle of the mobile charging service is currently providing charging service to a certain vehicle, which can be determined by the status of the mobile charging vehicle monitored by the mobile charging management system.

[0094] In this embodiment, the method for obtaining the predicted remaining service time and predicted remaining service power of the charging service being performed by the mobile charging vehicle is as follows:

[0095] Read the battery model of the vehicle being charged, retrieve the preset battery model-charging time, battery capacity, and charging loss (i.e., the non-calibrated battery capacity loss of the mobile charging vehicle caused during the charging process), and determine the charging time, battery capacity, and battery loss corresponding to the battery model of the current vehicle being charged;

[0096] Read the remaining battery capacity of the charged vehicle before charging, and use the product of the ratio between the difference between the corresponding battery capacity and the remaining battery capacity and the corresponding battery capacity and the corresponding charging time as the predicted remaining service time of the charging service being performed by the mobile charging vehicle;

[0097] The difference between the remaining power of the mobile charging vehicle before the service is performed, the battery capacity corresponding to the battery model of the currently charged vehicle, and the corresponding charging loss (the product of the ratio between the difference between the corresponding battery capacity and the remaining battery capacity and the corresponding battery capacity and the battery loss corresponding to the battery model of the currently charged vehicle) is used as the predicted service remaining power of the charging service being performed by the mobile charging vehicle;

[0098] The predicted remaining service time of the charging service being performed by the mobile charging vehicle is the predicted time required for the mobile charging vehicle to complete the charging service being performed;

[0099] The predicted service remaining power of the charging service being performed by the mobile charging vehicle is the predicted remaining battery capacity after the mobile charging vehicle completes the charging service being performed (referring to the capacity of the battery that performs the charging service).

[0100] In this embodiment, the current remaining power of the mobile charging vehicle is the current remaining capacity of the battery of the mobile charging vehicle that performs charging service, which is obtained through the status of the mobile charging vehicle monitored by the mobile charging management system.

[0114] The real-time maintained traffic flow of each sub-region at all statistical moments in the historical period is obtained from the historical maintained traffic flow data of each sub-region;

[0115] Based on the real-time maintained traffic volume of each sub-region at all statistical moments in the historical period and the number of orders initiated in the corresponding sub-region at all statistical moments, the quantitative relationship between the real-time maintained traffic volume and the number of orders initiated in each sub-region is analyzed;

[0116] The real-time maintained traffic flow of each sub-region is substituted into the quantitative relationship between the real-time maintained traffic flow of the corresponding sub-region and the number of orders initiated to obtain the predicted number of mobile charging vehicles required for each sub-region.

[0126] Determine whether there are duplicate mobile charging vehicles in the first preparation sequence of all sub-regions. If so, determine a set of candidate mobile charging vehicles for each sub-region based on the distance between the current location of each mobile charging vehicle and the central location point of a single sub-region in the complete coverage area, the state evaluation value of each mobile charging vehicle, and the sequence of mobile charging vehicles in each sub-region;

[0128] Based on the set of candidate mobile charging vehicles in each sub-region, a mobile charging vehicle for executing the service is allocated to each charging service initiation order as the order allocation result.

[0129] In this embodiment, the status evaluation value of each mobile charging vehicle is determined based on the service status of each mobile charging vehicle, including:

[0130] Input the service status of each mobile charging vehicle into a preset status evaluation model to obtain a status evaluation value of each mobile charging vehicle;

[0132] In this embodiment, the center position of the sub-region is the physical center of the sub-region.

[0133] In this embodiment, the set of mobile charging vehicles to be selected in the sub-region is a set of all mobile charging vehicles available for selection when all mobile charging vehicles that initiate charging service orders in the corresponding sub-region are allocated to perform services.

[0134] The beneficial effects of the above technology are as follows: by considering the distance between the current location corresponding to the movement and the central location point of a single sub-region within the complete coverage area, a reasonable determination of the set of mobile charging vehicles to be selected for each sub-region is achieved, and further by considering the distance between the current location of each mobile charging vehicle and the central location point of a single sub-region within the complete coverage area, the state evaluation value of each mobile charging vehicle and the sequence of mobile charging vehicles in each sub-region, while avoiding overlap between the sets of mobile charging vehicles to be selected for all sub-regions, the rationality of the determined set of mobile charging vehicles to be selected for each sub-region is further guaranteed. The set of mobile charging vehicles to be selected for each sub-region can allocate mobile charging vehicles to execute services for each charging service initiation order, thereby avoiding the situation where the overall order completion efficiency becomes low due to the single consideration of moving distance in allocating orders.

[0136] On the basis of Example 7, the mobile charging management method determines a set of mobile charging vehicles to be selected for each sub-region based on the distance between the current location of each mobile charging vehicle and the central location point of a single sub-region within the complete coverage area, the state evaluation value of each mobile charging vehicle, and the sequence of mobile charging vehicles in each sub-region, including:

[0137] The ratio of the distance between the current location of each mobile charging vehicle and the central location point of a single sub-region within the complete coverage area to the maximum value of the distances between the current location of all mobile charging vehicles and the central location point of a single sub-region within the complete coverage area is used as the distance evaluation value of each mobile charging vehicle relative to the corresponding sub-region;

[0138] Selecting the predicted number of mobile charging vehicles required multiple times from the mobile charging vehicle sequence in each sub-region to obtain all the selection results for each sub-region;

[0139] The average of the distance evaluation values ​​of all mobile charging vehicles in each optional result of each sub-region relative to the corresponding sub-region is taken as the comprehensive distance evaluation value of the corresponding optional result. At the same time, the average of the state evaluation values ​​of all mobile charging vehicles in each optional result of each sub-region is taken as the comprehensive state evaluation value of the corresponding optional result.

[0140] The final selection result of each sub-region is screened out from all the selection results of all sub-regions so that the average of the average degree of the comprehensive distance evaluation value and the average degree of the comprehensive state evaluation value of the final selection results of all sub-regions reaches the maximum, and all the mobile charging vehicles in the final selection result of each sub-region are summarized as the set of candidate mobile charging vehicles for each sub-region.

[0141] In this embodiment, the distance evaluation value of the sub-region indicates the relative size of the distance between the mobile charging vehicle and the central location point of the corresponding sub-region.

[0142] In this embodiment, all optional results of the sub-regions cover all possible situations that may occur when the predicted number of required mobile charging vehicles is selected from the mobile charging vehicle sequence of each sub-region, and each optional result represents one situation.

[0143] In this embodiment, the comprehensive distance evaluation value of the optional result represents the average value of the relative sizes of the distances between all mobile charging vehicles in the optional result and the central location point of the corresponding sub-region.

[0144] In this embodiment, the comprehensive status evaluation value of the optional result represents the average value of the status evaluation values ​​of all mobile charging vehicles in the optional result.

[0145] In this embodiment, the average degree of the comprehensive distance evaluation values ​​of the final selection results of all sub-regions is:

[0146] The square root of the sum of the squares of the differences between the comprehensive spacing evaluation values ​​of the final selection results of all sub-regions and the mean of the comprehensive spacing evaluation values ​​of the final selection results of all sub-regions is taken as the non-average degree of the comprehensive spacing evaluation values ​​of the final selection results of all sub-regions;

[0147] The non-average degree between 1 and the comprehensive distance evaluation value of the final selection results of all sub-regions is taken as the average degree of the comprehensive distance evaluation value of the final selection results of all sub-regions.

[0148] In this embodiment, the average degree of the comprehensive status evaluation values ​​of the final selection results of all sub-regions is:

[0149] The square root of the sum of the squares of the differences between the comprehensive status evaluation values ​​of the final selection results of all sub-regions and the mean of the comprehensive status evaluation values ​​of the final selection results of all sub-regions is taken as the non-average degree of the comprehensive status evaluation values ​​of the final selection results of all sub-regions;

[0150] The non-average degree between 1 and the comprehensive status evaluation value of the final selection results of all sub-regions is regarded as the average degree of the comprehensive status evaluation value of the final selection results of all sub-regions.

[0151] The beneficial effects of the above technology are: based on the distance evaluation value of each mobile charging vehicle relative to the corresponding sub-region and the state evaluation value of each mobile charging vehicle, the comprehensive distance evaluation value and the comprehensive state evaluation value of each selection result of each sub-region obtained by selecting the predicted number of mobile charging vehicles required in the mobile charging vehicle sequence of each sub-region multiple times are accurately obtained, and further, by screening out the final selection result of each sub-region that makes the average degree of the comprehensive distance evaluation value and the average degree of the comprehensive state evaluation value of the final selection result of all sub-regions reach the maximum among all the selection results of all sub-regions, and aggregating all the mobile charging vehicles in the final selection result of each sub-region as the set of mobile charging vehicles to be selected for each sub-region, it is ensured that the average state and average service distance of all mobile charging vehicles in the set of mobile charging vehicles to be selected in all sub-regions finally obtained are relatively average, thereby avoiding the situation where the imbalance between the distance and quality of charging services leads to a decrease in the overall quality and efficiency of charging services.

[0152] Embodiment 9:

[0153] On the basis of Embodiment 7, the mobile charging management method allocates a mobile charging vehicle for executing the service for each charging service initiation order as an order allocation result based on the set of mobile charging vehicles to be selected in each sub-region, including:

[0154] In the set of candidate mobile charging vehicles in the sub-region to which the service location of each charging service initiation order belongs, a mobile charging vehicle with the smallest distance between the corresponding current location and the service location of the corresponding charging service initiation order is selected as the assigned mobile charging vehicle for each charging service initiation order;

[0155] Determine whether there is at least one charging service initiation order group with overlapping corresponding assigned mobile charging vehicles among all charging service initiation orders. If so, the corresponding assigned mobile charging vehicle is regarded as the mobile charging vehicle for executing the charging service initiation order with the earliest order initiation time in the corresponding charging service initiation order group, and continue to screen out the mobile charging vehicle with the second smallest distance between the corresponding current location and the service location of the corresponding charging service initiation order from the set of candidate mobile charging vehicles of the sub-region to which the service location of each charging service initiation order that is not assigned in the corresponding charging service initiation order group belongs, as the new assigned mobile charging vehicle for each charging service initiation order, until there is no charging service initiation order group with overlapping corresponding assigned mobile charging vehicles among all charging service initiation orders, and the currently assigned mobile charging vehicles of all charging service initiation orders are regarded as the order matching result;

[0156] Otherwise, the currently assigned mobile charging vehicles for all charging service orders initiated are regarded as the order results.

[0157] The beneficial effect of the above technology is: by screening out the mobile charging vehicle with the shortest distance between the corresponding current location and the service location of the corresponding charging service initiation order, as the assigned mobile charging vehicle for each charging service initiation order and judging whether there is at least one charging service initiation order group in which the corresponding assigned mobile charging vehicles overlap among all charging service initiation orders, under the premise of ensuring that the charging service distance is small enough, the conflicts in the allocation of charging service initiation orders are avoided, thereby ensuring the overall quality of the charging service.
