[0002] This disclosure is based on and claims priority to a Chinese patent application with application number 202410912357.0, filing date July 9, 2024, and invention title "Billing Method, Device, Equipment, Storage Medium and Program Product for Vehicle Charging". The entire content of this Chinese patent application is incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of charging technologies, and particularly to a billing method, device, equipment, storage medium and program product for vehicle charging. Background Art

[0004] Currently, with the rapid development of new - energy vehicle technologies and the rapid increase in the ownership of new - energy vehicles in cities, the charging facilities配套 to new - energy vehicles have also developed rapidly accordingly. To meet the charging needs of new - energy vehicles to the greatest extent, related technologies use ultra - fast charging piles or fast - charging piles to charge new - energy vehicles. However, the billing strategies for ultra - fast charging piles or fast - charging piles in related technologies often only relate to the charging power consumption, and such billing strategies do not conform to the economic benefit models of ultra - fast charging piles or fast - charging piles, resulting in relatively low accuracy of the billing results for ultra - fast charging piles or fast - charging piles. Summary of the Invention

[0005] [[ID=2,1]]In view of this, at least one billing method, device, equipment, storage medium and program product for vehicle charging are provided in the embodiments of this disclosure.

[0006] The technical solutions of the embodiments of this disclosure are implemented as follows:

[0007] In a first aspect, an embodiment of this disclosure provides a billing method for vehicle charging, the billing method including:

[0008] Obtain at least one charging power information during the charging process of the vehicle and the charging power consumption of the vehicle; the charging power information includes a charging power range and the charging duration corresponding to the charging power range;

[0009] Determine the charging time cost of the vehicle based on at least one charging power range and the charging duration respectively corresponding to at least one charging power range;

[0010] Determine the charging power consumption cost of the vehicle based on the charging power consumption;

[0011] Determine the charging cost of the vehicle based on the charging power consumption cost of the vehicle and the charging time cost of the vehicle;

[0012] Before the vehicle is charged, the billing method also includes:

[0013] Based on the vehicle type information, at least two predicted power ranges for the vehicle are determined.

[0014] The unit price for vehicle charging time is determined based on at least two predicted power ranges and the unit price of the power range corresponding to each of the at least two predicted power ranges.

[0015] The sum of the preset unit price of electricity, unit price of electricity service, and unit price of charging time fee is determined as the predicted unit price of charging for the vehicle.

[0016] In this embodiment, the charging time cost of a vehicle can be determined by the charging power range and the corresponding charging time during the charging process, and the charging power cost can be determined by the charging capacity of the vehicle. Finally, the charging time cost and the charging capacity cost are combined to form the vehicle's total charging cost. Thus, the final vehicle charging cost includes not only the charging capacity cost but also the charging time cost related to the charging power and charging time. This reflects the time-sensitive nature of supercharging or fast charging stations and aligns with their economic benefit models, thereby improving the accuracy of the final billing result. Simultaneously, the unit price for the charging time cost is determined by the predicted power range of the vehicle. The sum of the preset unit price for electricity, the unit price for electricity service, and the unit price for charging time cost is used to determine the predicted charging unit price. This standardizes the display unit of the vehicle's charging unit price, allowing users to more accurately predict the final charging cost based on this predicted unit price.

[0017] In some embodiments, determining the charging time cost of a vehicle based on at least one charging power range and the charging duration corresponding to each of the at least one charging power range includes: for each charging power range, determining the unit price of the charging power range; for each charging power range, determining the charging time range cost of the charging power range based on the unit price of the charging power range and the charging duration corresponding to the charging power range; and determining the charging time range cost of the vehicle by summing the charging time range costs corresponding to each of the at least one charging power range.

[0018] In this embodiment, the unit price corresponding to each charging power range is determined, and then the charging time range cost for each charging power range is determined based on the unit price and charging duration. Finally, the sum of the charging time range costs for each charging power range is determined as the vehicle's charging time cost. In this way, the vehicle's charging time cost is ranged according to its charging power; different charging powers and the duration of charging at those powers correspond to different charging time range costs. This allows for a more precise determination of the final charging time cost, thus better reflecting the charging characteristics of fast-charging or supercharging stations.

[0019] In some embodiments, the method further includes: obtaining vehicle model information of the vehicle; the vehicle model information is used to characterize the charging type that the vehicle can use during charging; for each charging power range, based on the vehicle model information, updating the charging time range cost of the charging power range to obtain the updated charging time range cost of the charging power range; and determining the charging time cost of the vehicle by summing the charging time range costs corresponding to at least one charging power range, including: determining the charging time cost of the vehicle by summing the updated charging time range costs corresponding to at least one charging power range.

[0020] In this embodiment of the disclosure, the charging time interval fee corresponding to each charging power interval during the charging process can be adjusted by using the vehicle model information, thereby improving the billing flexibility and enabling the final charging fee to not only reflect the charging characteristics of the charging pile but also conform to the vehicle model characteristics.

[0021] In some embodiments, determining the charging cost based on the charging volume includes: determining the charging cost based on the charging volume and a preset unit price for the charging volume; determining the charging service cost based on the charging volume and the unit price for the charging service; the unit price for the charging service is determined based on the vehicle model information; and determining the charging cost as the sum of the charging cost and the charging service cost.

[0022] In this embodiment, the unit price of electricity service is determined by the vehicle model information, and the charging service fee is determined by the unit price of electricity service and the charging amount. This allows for the determination of charging service fees corresponding to different vehicle models, resulting in a more accurate match between the final determined charging service fee and the vehicle model, thus improving the accuracy of the charging service fee determination.

[0023] In some embodiments, the charging capacity includes charging sub-capacities corresponding to at least one charging power range; the unit price of the power service includes a unit price of the power service corresponding to at least one charging power range; and the charging service fee is determined based on the charging capacity and the unit price of the power service, including: for each charging power range, determining a charging service sub-fee for the charging power range based on the unit price of the power service for the charging power range and the charging sub-capacities corresponding to the charging power range; and determining the sum of at least one charging service sub-fees as the charging service fee.

[0024] In this embodiment, the charging service sub-fee for each charging power range is determined based on the sub-unit price of the power service corresponding to each charging power range and the sub-chargeable power corresponding to each charging power range. Finally, the sum of the charging service sub-fees for each charging power range is determined as the vehicle's charging service fee. In this way, by grading the vehicle's charging power into ranges, different charging power levels correspond to different sub-chargeable power levels and thus different charging service sub-fees. This allows for a more precise determination of the final charging service fee, better reflecting the charging characteristics of fast-charging or supercharging stations.

[0025] In some embodiments, the method further includes: obtaining the vehicle's occupancy time; the occupancy time is the time during which the vehicle is in the charging platform but not charging; determining the vehicle's occupancy fee based on the occupancy time and the occupancy unit price; and determining the vehicle's charging fee based on the vehicle's charging power cost and the vehicle's charging time cost, including: determining the vehicle's charging fee based on the charging power cost, the charging time cost, and the occupancy fee.

[0026] In this embodiment of the disclosure, the parking fee for a vehicle can be determined by determining the parking time of the vehicle, thereby enabling the vehicle to enter the charging process or leave the charging platform as soon as possible, thus improving charging efficiency.

[0027] In some embodiments, determining the charging time cost per unit price of a vehicle based on at least one predicted power range and the power range unit price corresponding to each of the at least one predicted power range includes: determining the predicted average power of the vehicle based on at least one predicted power range; determining the predicted charging time of the vehicle based on the predicted charging amount of the vehicle and the predicted average power of the vehicle; determining the average power range unit price based on the power range unit price corresponding to each of the at least one predicted power range; and determining the charging time cost per unit price of the vehicle based on the predicted charging time of the vehicle, the average power range unit price, and the predicted charging amount of the vehicle.

[0028] In this embodiment, the predicted average power of the vehicle is determined by the predicted power range; the predicted charging capacity and the predicted average power of the vehicle are used to determine the predicted charging time; the average power range unit price is determined by the power range unit price within the predicted power range; and the charging time cost unit price is determined by the predicted charging time, the average power range unit price, and the predicted charging capacity of the vehicle. This allows for a unified unit for the charging time cost unit price, the energy unit price, and the energy service unit price, enabling the sum of the charging time cost unit price, the energy unit price, and the energy service unit price to be used as the predicted charging cost unit price of the vehicle.

[0029] Secondly, embodiments of this disclosure provide a billing device for vehicle charging, the billing device for vehicle charging comprising:

[0030] The acquisition unit is used to acquire at least one charging power information and the charging capacity of the vehicle during the charging process; the charging power information includes the charging power range and the charging time corresponding to the charging power range.

[0031] The first determining unit is used to determine the charging time cost of the vehicle based on at least one charging power range and the charging time corresponding to each of the at least one charging power range.

[0032] The second determining unit is used to determine the charging cost of the vehicle based on the charging amount.

[0033] The third determining unit is used to determine the charging cost of the vehicle based on the charging power cost and the charging time cost of the vehicle.

[0034] The fifth determining unit is used to determine at least two predicted power ranges for the vehicle based on the vehicle type information; determine the charging time cost unit price for the vehicle based on the at least two predicted power ranges and the power range unit price corresponding to the at least two predicted power ranges respectively; and determine the predicted charging unit price for the vehicle by summing the preset electricity unit price, electricity service unit price and charging time cost unit price.

[0035] Thirdly, embodiments of this disclosure provide a billing device for vehicle charging, including a memory and a processor. The memory stores a computer program that can run on the processor, and the processor executes the program to implement some or all of the steps in the above method.

[0050] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this disclosure are further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limitations on this disclosure. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0051] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0052] The terms “first / second / third” are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that “first / second / third” may be interchanged in a specific order or sequence where permitted, so that the embodiments of this disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of this disclosure.

[0054] Currently, charging stations can be categorized into slow charging stations, fast charging stations, and supercharging stations based on their charging power. Because fast and supercharging stations have higher charging power, their charging times are often shorter. In other words, fast and supercharging stations have strong charging timeliness. However, when billing for fast and supercharging stations with strong charging timeliness, related technologies often focus only on the amount of electricity charged, such as calculating charging fees based on the amount of electricity charged and the unit price of electricity. It is evident that the billing strategies in these technologies do not take into account the strong charging timeliness characteristics of fast and supercharging stations, leading to inaccurate billing.

[0055] To address the issue of inaccurate billing in related technologies, this disclosure provides a billing method for vehicle charging, which can be applied to a charging platform. The charging platform controls charging equipment to charge vehicles. This charging equipment includes at least supercharging piles and fast charging piles. In some embodiments, the above-described billing method can be applied to electronic devices within the charging platform. These electronic devices include, but are not limited to, fixed and / or mobile devices. For example, fixed devices include, but are not limited to, personal computers (PCs) or servers, where the server can be a cloud server or a regular server.

[0056] Figure 1 is a schematic diagram of the implementation process of a vehicle charging billing method according to an embodiment of this disclosure. As shown in Figure 1, the vehicle charging billing method can be implemented through steps S101 to S104:

[0057] Step S101: Obtain at least one charging power information and the vehicle's charging capacity during the charging process.

[0058] Here, charging power information includes the charging power range of the vehicle during the charging process and the charging duration within that range. The charging power range can be determined through the real-time charging power of the vehicle during the charging process. The vehicle's charging capacity refers to the amount of electricity output by the charging equipment controlled by the charging platform when charging is complete.

[0059] In this embodiment, the charging platform can monitor the real-time charging power used by the charging equipment when charging the vehicle. After the vehicle is fully charged, it acquires multiple real-time charging powers during the charging process, as well as the charging duration corresponding to each real-time charging power. Then, it determines at least one charging power range based on the multiple real-time charging powers. Finally, based on the charging duration of the real-time charging power within each charging power range, it obtains the charging duration corresponding to each charging power range.

[0060] For example, the vehicle's real-time charging power during the charging process includes 50kW, 100kW, 150kW, 200kW, 250kW, and 300kW, where: 50kW and 100kW correspond to a charging time of 1 minute, 150kW to 2 minutes, 200kW and 250kW to 3 minutes, and 300kW to 4 minutes. Therefore, the charging power ranges can include: Charging power range 1: 0 to 100kW, Charging power range 2: 100kW to 200kW, and Charging power range 3: 200kW to 300kW. The charging time corresponding to charging power range 1 is 1 minute for 50kW + 1 minute for 100kW = 2 minutes; the charging time corresponding to charging power range 2 is 2 minutes for 150kW + 3 minutes for 200kW = 5 minutes; and the charging time corresponding to charging power range 3 is 3 minutes for 250kW + 4 minutes for 300kW = 7 minutes.

[0061] In some embodiments, the division of charging power ranges can be preset, and the setting method can be consistent with the method of dividing charging power into slow charging, fast charging, and supercharging. That is, by obtaining the charging power range of the vehicle during the charging process and the corresponding charging time for each range, the charging method used by the vehicle and the duration of that charging method can be determined. In other embodiments, the division of charging power ranges may differ from the method of dividing charging power into slow charging, fast charging, and supercharging. This disclosure does not limit the method of dividing charging power ranges.

[0062] Step S102: Determine the charging time cost of the vehicle based on at least one charging power range and the charging time corresponding to each of the at least one charging power range.

[0063] Understandably, fast charging stations and supercharging stations offer shorter charging times and higher charging efficiency. To reflect this efficiency in billing, the charging time cost can be determined by the charging power range used by the vehicle during charging and the duration of that range.

[0064] In this embodiment, a predetermined unit price for each charging power range can be obtained. The charging time range fee for each charging power range is determined based on the unit price and charging duration. The sum of the charging time range fees for at least one charging power range is then used to determine the vehicle's charging time fee. Different charging power ranges correspond to different unit prices. It is understood that the higher the average charging power of a charging power range, the greater the amount of electricity provided to the vehicle per unit time by the charging pile, and therefore the higher the unit price for that range. Thus, the charging time range fee for a given charging power range can be determined by multiplying the vehicle's continuous charging time within that range by the unit price.

[0065] Step S103: Determine the charging cost of the vehicle based on the charging amount.

[0066] In this embodiment of the disclosure, the charging cost for the vehicle may include an electricity cost. A predetermined unit price for electricity can be obtained, and the product of the charging amount and the unit price for electricity is determined as the vehicle's electricity cost.

[0067] In some embodiments, the unit price of electricity can be a fixed value, such as 0.8 yuan / kWh. In other embodiments, the unit price of electricity can be a variable value, related to the charging time. For example, when the vehicle is charged from midnight to 6 a.m., which is an off-peak electricity consumption period, the unit price of electricity will be lower, such as 0.6 yuan / kWh; when the vehicle is charged from 6 a.m. to midnight, which is a peak electricity consumption period, the unit price of electricity will be higher, such as 1 yuan / kWh.

[0068] In some embodiments, the charging cost may also include a charging service fee. A predetermined unit price for the charging service can be obtained, and the product of the charging amount and the unit price for the charging service is determined as the charging service fee for the vehicle.

[0069] In some embodiments, the unit price for electricity service can be a fixed value, such as 0.4 yuan / kWh. In other embodiments, the unit price for electricity service can be a variable value, in which case the unit price for electricity service is related to the charging power of the vehicle; the higher the charging power, the higher the unit price for electricity service.

[0070] Step S104: Determine the charging cost of the vehicle based on the charging power cost and the charging time cost.

[0071] In this embodiment of the disclosure, the sum of the vehicle's charging power cost and the charging time cost can be determined as the vehicle's charging cost.

[0072] In this embodiment, the charging time cost of the vehicle can be determined by the charging power range and the corresponding charging time during the charging process, and the charging power cost can be determined by the charging amount. Finally, the charging time cost and the charging power cost are combined to determine the total charging cost of the vehicle. Thus, the final charging cost includes not only the charging power cost but also the charging time cost related to the charging power and charging time. This reflects the time-sensitive nature of supercharging or fast charging stations, aligning with their economic benefit models and improving the accuracy of the final billing result.

[0073] In some embodiments, as shown in FIG2, step S102 can also be implemented by steps S201 to S203:

[0074] Step S201: For each charging power range, determine the unit price of the corresponding power range based on the charging power range.

[0075] In this embodiment of the disclosure, the correspondence between different charging power ranges and different unit prices of power ranges can be obtained first. Then, based on each charging power range of the vehicle, the corresponding unit price of the power range can be determined from multiple correspondences. The unit price of the power range is positively correlated with the average power of the charging power range.

[0076] It is understandable that fast charging stations and supercharging stations have strong charging time sensitivity. In order to reflect this charging characteristic in the billing results, the higher the charging power used by the vehicle during the charging process, the higher the unit price of the corresponding power range.

[0077] For example, the correspondence between different charging power ranges and different unit prices for different power ranges can be as follows: 0-100kW corresponds to 0.2 yuan / minute, 100-200kW corresponds to 0.3 yuan / minute, 200-300kW corresponds to 0.4 yuan / minute, and 300-400kW corresponds to 0.5 yuan / minute.

[0078] Step S202: For each charging power range, determine the charging time range cost based on the unit price of the power range and the charging time corresponding to the charging power range.

[0079] In this embodiment of the disclosure, after obtaining the unit price of each charging power range corresponding to each charging power range of the vehicle, the product of the charging time corresponding to the charging power range and the unit price of the charging power range can be determined as the charging time range cost corresponding to a charging power range.

[0080] For example, the charging power range includes 0-100kW, 100-200kW, and 200-300kW. The charging time for 0-100kW is 2 minutes, for 100-200kW it is 3 minutes, and for 200-300kW it is 5 minutes. The charging time for 0-100kW is 0.2 yuan / minute, for 100-200kW it is 0.3 yuan / minute, and for 200-300kW it is 0.4 yuan / minute. Therefore, the charging time range fee for 0-100kW is 2 × 0.2 = 0.4 yuan; the charging time range fee for 100-200kW is 3 × 0.3 = 0.9 yuan; and the charging time range fee for 200-300kW is 5 × 0.4 = 2 yuan.

[0081] Step S203: The sum of the charging time interval fees corresponding to at least one charging power interval is determined as the charging time fee of the vehicle.

[0082] For example, the charging power range of the vehicle during the charging process includes 0-100kW, 100-200kW, and 200-300kW. The charging time range cost corresponding to 0-100kW is 2×0.2=0.4 yuan; the charging time range cost corresponding to 100-200kW is 3×0.3=0.9 yuan; and the charging time range cost corresponding to 200-300kW is 5×0.4=2 yuan. Therefore, the charging time cost of the vehicle is 0.4+0.9+2=3.3 yuan.

[0083] In this embodiment, the unit price corresponding to each charging power range is determined, and then the charging time range cost for each charging power range is determined based on the unit price and charging duration. Finally, the sum of the charging time range costs for each charging power range is determined as the vehicle's charging time cost. In this way, the vehicle's charging time cost is ranged according to its charging power; different charging powers and the duration of charging at those powers correspond to different charging time range costs. This allows for a more precise determination of the final charging time cost, thus better reflecting the charging characteristics of fast-charging or supercharging stations.

[0084] In some embodiments, as shown in FIG3, the above method can also be implemented by steps S301 and S302, and step S203 can be implemented by step S303:

[0085] Step S301: Obtain the vehicle model information.

[0086] Here, vehicle model information is used to characterize the charging type that the vehicle can use during the charging process. For example, when the vehicle model information is a Supercharger model, it means that the vehicle can use a higher charging power, i.e., the charging type is Supercharger charging; when the vehicle model information is a standard model, it means that the vehicle can use a lower charging power, i.e., the charging type is standard charging.

[0087] In some embodiments, when the vehicle is in communication connection with the charging platform, the charging platform can obtain the vehicle model information through a preset communication protocol.

[0088] Step S302: For each charging power range, based on the vehicle model information, update the charging time range cost for the charging power range to obtain the updated charging time range cost for the charging power range.

[0089] In this embodiment, the unit price of each charging power range can be updated first based on the vehicle model information. Then, based on the updated unit price of each charging power range and the corresponding charging time, the updated charging time range cost for each charging power range is determined. The update method for the unit price of the power range can be to obtain an update coefficient corresponding to the vehicle model information and update the unit price of each charging power range based on the update coefficient. This update coefficient is related to the average charging power used by the vehicle.

[0090] In this embodiment of the disclosure, when the vehicle model information is a supercharging model, it indicates that the vehicle can use supercharging during the charging process, and the average charging power used by the vehicle is relatively high. In this case, a smaller update coefficient can be determined, such as 0.8. When the vehicle model information is a regular model, it indicates that the vehicle uses regular charging during the charging process, and the average charging power used by the vehicle is relatively low. In this case, a larger update coefficient can be determined, such as 1.1.

[0091] In this embodiment of the disclosure, the updated power range unit price of the charging power range can be determined by multiplying the power range unit price of the charging power range by the corresponding update coefficient. The updated charging time range cost of the charging power range can be determined by multiplying the updated power range unit price of the charging power range by the corresponding charging time.

[0092] It is understood that the billing method provided in this disclosure is applied to charging platforms capable of supercharging or fast charging. Therefore, when ordinary vehicles are charged on these platforms, they cannot utilize the time-sensitive supercharging or fast charging methods due to vehicle limitations. Consequently, they can only continuously use lower charging power, resulting in a lower unit price for the power range. Continuing to use the initial power range for billing would not satisfy the economic efficiency model of supercharging or fast charging stations. Therefore, for vehicles that cannot use supercharging or fast charging, the initial power range unit price needs to be increased. Similarly, for supercharging vehicles, since higher charging power can be continuously used during charging, and the corresponding power range unit price is also higher, a lower update coefficient can be used to reduce the initial power range unit price.

[0093] Step S303: The sum of the updated charging time interval fees corresponding to at least one charging power interval is determined as the vehicle's charging time fee.

[0094] In this embodiment of the disclosure, after updating the charging time interval cost for each charging power interval, the sum of the updated charging time interval costs for all charging power intervals can be determined as the vehicle's charging time cost.

[0095] In this embodiment of the disclosure, the charging time interval fee corresponding to each charging power interval during the charging process can be adjusted by using the vehicle model information, thereby improving the billing flexibility and enabling the final charging fee to not only reflect the charging characteristics of the charging pile but also conform to the vehicle model characteristics.

[0096] In some embodiments, as shown in FIG4, step S103 above can be implemented by steps S401 to S403:

[0097] Step S401: Determine the electricity cost based on the charging capacity and the preset electricity unit price.

[0098] In this embodiment of the disclosure, the product of the charging capacity and the unit price of electricity can be used to determine the electricity cost. For example, when the unit price of electricity is 0.8 yuan / kWh and the vehicle's charging capacity is 50 kWh, the electricity cost can be 40 yuan.

[0099] In some embodiments, the unit price of electricity corresponds to the charging period of the vehicle, with the unit price of electricity during peak charging periods being higher than that during off-peak charging periods. For example, the unit price of electricity during peak charging periods may be 1 yuan / kWh, and the unit price of electricity during off-peak charging periods may be 0.6 yuan / kWh.

[0100] Step S402: Determine the charging service fee based on the charging capacity and the unit price of the electricity service; the unit price of the electricity service is determined based on the vehicle model information.

[0101] Step S403: The sum of the electricity cost and the charging service cost is determined as the charging electricity cost.

[0102] In this embodiment of the disclosure, the initial electricity service unit price can be obtained first, then the update coefficient can be determined according to the vehicle model, the product of the update coefficient and the initial electricity service unit price can be determined as the electricity service unit price, and finally the product of the updated electricity service unit price and the charging amount can be determined as the charging service fee of the vehicle.

[0103] For example, if the vehicle is a supercharging vehicle with a charging capacity of 50 kWh, the initial electricity service unit price is 0.4 yuan / kWh, the update coefficient corresponding to the supercharging vehicle is 0.8, then the updated electricity service unit price is 0.32, and the final charging service fee is 0.32 × 50 = 16 yuan.

[0104] In this embodiment, the unit price of electricity service is determined by the vehicle model information, and the charging service fee is determined by the unit price of electricity service and the charging amount. This allows for the determination of charging service fees corresponding to different vehicle models, resulting in a more accurate match between the final determined charging service fee and the vehicle model, thus improving the accuracy of the charging service fee determination.

[0105] In some embodiments, as shown in FIG4, the charging capacity includes charging sub-capacities corresponding to at least one charging power range; the electricity service unit price includes electricity service sub-unit prices corresponding to at least one charging power range; the above step S402 can be implemented by steps S4021 and S4022:

[0106] Step S4021: For each charging power range, determine the charging service sub-cost for the charging power range based on the sub-unit price of the power service and the sub-charge of the charging power range.

[0107] Step S4022: The sum of at least one charging service sub-fees is determined as the charging service fee.

[0108] It's understandable that charging stations use multiple charging power levels to charge vehicles, ultimately resulting in the vehicle's battery receiving a charge. In other words, the amount of charge received is related to the charging power. For example, when a vehicle first starts charging, if the charging power range is 0 to 100 kW for 2 minutes, the battery receives 2 kWh; 200 to 300 kW for 2 minutes, the battery receives 5 kWh; and 400 kW for 6 minutes, the battery receives 40 kWh. Therefore, the total charge (47 kWh) includes the 2 kWh from 0 to 100 kW, the 5 kWh from 200 to 300 kW, and the 40 kWh from 400 kW.

[0109] In this embodiment of the disclosure, the sub-unit price of electricity service corresponding to each charging power range is also different.

[0110] Continuing with the example above: the sub-unit price for electricity service from 0 to 100 kW can be 0.1 yuan / kWh, so the sub-cost for charging service from 0 to 100 kW would be 0.1 × 2 = 0.2 yuan; for 200 to 300 kW, it can be 0.2 yuan / kWh, so the sub-cost for charging service from 200 to 300 kW would be 0.2 × 5 = 1 yuan; and for 400 kW, the sub-unit price for electricity service can be 0.4 yuan / kWh, so the sub-cost for charging service from 400 kW would be 0.4 × 40 = 16 yuan. Finally, the total charging service cost is 0.2 + 1 + 16 = 17.2 yuan.

[0111] In this embodiment, the charging service sub-fee for each charging power range is determined based on the sub-unit price of the power service corresponding to each charging power range and the sub-chargeable power corresponding to each charging power range. Finally, the sum of the charging service sub-fees for each charging power range is determined as the vehicle's charging service fee. In this way, by grading the vehicle's charging power into ranges, different charging power levels correspond to different sub-chargeable power levels and thus different charging service sub-fees. This allows for a more precise determination of the final charging service fee, better reflecting the charging characteristics of fast-charging or supercharging stations.

[0112] In some embodiments, as shown in FIG5, the above method can also be implemented by steps S501 and S502, and correspondingly, step S104 can be implemented by step S503:

[0113] Step S501: Obtain the vehicle's occupancy time.

[0114] Here, the "positioning time" refers to the time a vehicle is within the charging platform but not charging. This positioning time can include both the time before and after the vehicle begins charging.

[0115] Step S502: Determine the parking fee for the vehicle based on the parking time and the parking unit price.

[0116] In this embodiment of the disclosure, the product of the occupancy time and the occupancy unit price can be used to determine the vehicle occupancy fee. The occupancy unit price can be preset. For example, the occupancy unit price can be 0.32 yuan per minute.

[0117] It's understandable that fast charging stations and supercharging stations have a strong time-sensitive charging characteristic. This characteristic is only apparent during the charging process. Therefore, to improve charging efficiency and maximize the charging capabilities of fast and supercharging stations, a parking fee should be determined based on the vehicle's parking time during the period when the vehicle is not charging.

[0118] Step S503: Determine the vehicle's charging cost based on the charging power cost, charging time cost, and parking space cost.

[0119] In this embodiment of the disclosure, the sum of the charging power cost, the charging time cost, and the parking space cost can be determined as the vehicle's charging cost.

[0120] In this embodiment of the disclosure, the parking fee for a vehicle can be determined by determining the parking time of the vehicle, thereby enabling the vehicle to enter the charging process or leave the charging platform as soon as possible, thus improving charging efficiency.

[0121] In some embodiments, as shown in FIG6, the above method can also be implemented through steps S601 to S603:

[0122] Step S601: Based on the vehicle type information, determine at least one predicted power range for the vehicle.

[0123] In this embodiment of the disclosure, steps S601 to S603 can be performed before the vehicle is charged.

[0124] Here, the predicted power range refers to the power range that the vehicle is most likely to use during charging. It's understandable that the power range used by the vehicle during charging is related to the charging type, which in turn is related to the vehicle's vehicle type information. For example, when the vehicle is a supercharger, the charging type is likely supercharger charging, so the power range used during charging is 0 to 400 kW. When the vehicle is a regular vehicle, the charging type is likely regular charging, so the power range used during charging is 0 to 200 kW. Therefore, at least one predicted power range for the vehicle can be predicted using the vehicle type information.

[0125] Step S602: Determine the unit price of vehicle charging time based on at least one predicted power range and the unit price of the power range corresponding to each predicted power range.

[0126] Step S603: The sum of the preset unit price of electricity, unit price of electricity service, and unit price of charging time fee is determined as the predicted unit price of charging for the vehicle.

[0127] It is understood that the vehicle charging cost determined by the billing method provided in this disclosure consists of a charging time cost and a charging capacity cost, with the charging time cost determined based on the vehicle's charging power and the corresponding charging duration. Therefore, to enable users to predict the cost of charging before starting, this disclosure determines a unit price for the charging time cost, ensuring that the final predicted charging unit price includes the charging time cost. This allows users to more accurately predict the cost of charging after obtaining the predicted charging unit price.

[0128] In some embodiments, the charging platform's human-machine interface includes a unit price display control for displaying the predicted charging unit price of the vehicle. After a user triggers the unit price display control, the charging platform can respond to the trigger operation by displaying the predicted charging unit price of the vehicle on the human-machine interface. This allows the user to obtain the predicted charging unit price and predict the charging cost for the current charge based on that price.

[0129] In this embodiment, at least one predicted power range for the vehicle is first determined based on the vehicle type information. Then, the charging time cost per unit price is determined using the predicted power range and its unit price. Finally, the sum of the preset unit price for electricity, the unit price for electricity service, and the unit price for charging time is determined as the predicted charging cost per unit price for the vehicle. This standardizes the display unit of the vehicle's charging cost per unit price, allowing the predicted charging cost per unit price to be displayed on the human-machine interface after the user triggers the unit price display control on the platform. This enables the user to more accurately predict the final charging cost based on the predicted charging cost per unit price.

[0130] In some embodiments, step S602 can be implemented by steps S6021 to S6024:

[0131] Step S6021: Determine the predicted average power of the vehicle based on at least one predicted power range.

[0132] In this embodiment of the disclosure, the average of the minimum and maximum charging power in at least one predicted power range can be determined as the predicted average power of the vehicle. For example, if at least one predicted power range includes 0-100kW, 100-200kW, 200-300kW, and 300-400kW, then the predicted average power is 200kW.

[0133] Step S6022: Determine the predicted charging time of the vehicle based on the predicted charging capacity and the predicted average power of the vehicle.

[0134] In this embodiment, the predicted charging capacity of the vehicle is related to the capacity of the vehicle's battery pack. When the vehicle is connected to the charging platform, the charging platform can obtain the predicted charging capacity of the vehicle. After obtaining the predicted charging capacity, the quotient of the predicted charging capacity and the predicted average power can be determined as the predicted charging time of the vehicle. For example, if the predicted charging capacity of the vehicle is 50 kWh and the predicted average power of the vehicle is 200 kW, then the predicted charging time of the vehicle is 50 kWh / 200 kW = 15 minutes.

[0135] Step S6023: Determine the average power interval unit price based on the power interval unit price corresponding to at least one predicted power interval.

[0136] It is understandable that different predicted power ranges correspond to different unit prices for different power ranges. The correspondence between different predicted power ranges and different unit prices for different power ranges is consistent with the correspondence between different charging power ranges and different unit prices for different power ranges in the above embodiments.

[0137] In this embodiment of the disclosure, the average unit price of the power range in at least one predicted power region can be determined as the average unit price of the power range. For example, at least one predicted power region includes 0-100kW, 100-200kW, 200-300kW, and 300-400kW, with corresponding unit prices of 0.2 yuan / minute, 0.3 yuan / minute, 0.4 yuan / minute, and 0.5 yuan / minute, respectively. Therefore, the average unit price of the power range is (0.2+0.3+0.4+0.5) / 4 = 0.35 yuan / minute.

[0138] Step S6024: Determine the charging time cost per unit price of the vehicle based on the vehicle's predicted charging time, average power range unit price, and predicted charging capacity.

[0139] In this embodiment of the disclosure, the predicted range cost can be determined first based on the vehicle's predicted charging time and the average power range unit price. Specifically, the product of the predicted charging time and the average power range unit price can be determined as the predicted range cost. Then, the quotient of the predicted range cost and the predicted charging amount can be determined as the charging time cost unit price.

[0140] Understandably, the predicted interval cost can represent the predicted cost of charging time interval when the vehicle is charged using the average power interval. Then, in order to unify the unit with the unit price of electricity and the unit price of electricity service (i.e., yuan / kWh), the predicted interval cost can be divided by the predicted charging amount to obtain the predicted interval cost per kWh, which is the unit price of charging time cost.

[0141] In this embodiment, the predicted average power of the vehicle is determined by the predicted power range; the predicted charging capacity and the predicted average power of the vehicle are used to determine the predicted charging time; the average power range unit price is determined by the power range unit price within the predicted power range; and the charging time cost unit price is determined by the predicted charging time, the average power range unit price, and the predicted charging capacity of the vehicle. This allows for a unified unit for the charging time cost unit price, the energy unit price, and the energy service unit price, enabling the sum of the charging time cost unit price, the energy unit price, and the energy service unit price to be used as the predicted charging cost unit price of the vehicle.

[0142] In some embodiments, as shown in Figure 7, the above billing method can also be implemented through the following steps:

[0143] Step S701: Determine the vehicle's cross-power range.

[0144] Step S702: Determine the average power based on the vehicle's cross-power range.

[0145] In this embodiment of the disclosure, the average power is achieved by formula (1):

[0146] Step S703: Determine the charging time based on the vehicle's predicted charging capacity and average power.

[0147] In this embodiment of the disclosure, the charging time is achieved by formula (2):

[0148] Step S704: Determine the average service fee based on the interval service fee of each cross-power sub-interval across the power interval.

[0149] In this embodiment of the disclosure, the average service fee is achieved through formula (3):

[0150] Step S705: Determine the time service fee based on the vehicle's predicted charging capacity and average service fee.

[0151] In this embodiment of the disclosure, the time service fee is implemented by formula (4): Time service fee = predicted charging amount × average service fee formula (4).

[0152] Step S706: Determine the unit price of the time service fee based on the time service fee and the predicted charging amount of the vehicle.

[0153] In this embodiment of the disclosure, the unit price of the time service fee is implemented by formula (5):

[0154] Step S707: The sum of the time service fee unit price, the electricity fee unit price, and the electricity service fee unit price is determined as the price displayed to the user on the front end.

[0155] In some embodiments, as shown in Figure 8, the above billing method can also be implemented through the following steps:

[0156] Step S801: Determine the time service fee based on the charging time corresponding to the charging power range during the charging process and the power range service fee unit price corresponding to the charging power range.

[0157] In this embodiment of the disclosure, the time service fee is implemented using formula (6):

[0158] Where n is the total number of charging power ranges, and n is a positive integer.

[0159] Step S802: Determine the vehicle's electricity cost based on the vehicle's charging kilowatt-hours and the electricity price per unit.

[0160] In this embodiment of the disclosure, the electricity fee is calculated using formula (7): Electricity fee = Number of charging kilowatt-hours * Electricity unit price formula (7).

[0161] Step S803: Determine the vehicle's electricity service fee based on the vehicle's charging kilowatt-hours and the service fee unit price.

[0162] In this embodiment of the disclosure, the electricity fee is calculated using formula (8): Electricity service fee = Number of charging kilowatt-hours * Service fee unit price formula (8).

[0163] Step S804: Determine the order amount for the vehicle based on the vehicle's per-kilowatt-hour service fee, electricity fee, and time service fee.

[0164] In this embodiment of the disclosure, the order amount is realized by formula (9): Order amount = electricity fee + electricity service fee + time service fee formula (9).
