[0078] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.
[0079] like Figure 1 As shown, the consumption processing method of the embodiment of the present application is used in the consumption processing system of the vehicle charging station, and specifically includes the following steps:
[0080] 01: Get the vehicle information of the vehicle;
[0081] 02: Obtaining transaction information of the vehicle according to the vehicle information, wherein the transaction information includes expenditure information and / or income information;
[0082] 03: Based on the transaction information, the fees or income of the vehicle in the charging station are settled uniformly.
[0083] Specifically, the process of a vehicle using a V2G charging station generally includes entering the station, charging / discharging, and exiting the station. In order to make the process of the vehicle using related services in the charging station smoother, and in view of the characteristics that users obtain benefits when the V2G charging station transmits electricity to the power grid and users spend money when charging from the power grid, the present application provides a consumption processing method, which accesses and calls vehicle-related data at any time as needed through the communication network, thereby realizing the overall aggregation and process simplification of various business settlements in the charging station.
[0084] In some examples, when a vehicle enters a charging station, relevant information about the vehicle is queried, such as the vehicle's license plate number, vehicle identification code (VIN code), etc., so that when the information is called up in the system, it can be matched with the identified vehicle to avoid errors in the use and settlement of the service.
[0085] In the process of using various services between vehicles and charging stations, the expenditures or income generated by the relevant services are counted. In order to ensure that the counted expenditures or income correspond to the vehicles using the relevant services, before counting the expenditures and income, it is necessary to first call the vehicle information queried when the vehicle enters the station, and associate the counted expenditures and income with the vehicle information, so as to facilitate the subsequent unified settlement of the vehicle's expenditures or income in the charging station.
[0086] Before the vehicle leaves the charging station, the vehicle's expenditure or income is settled uniformly. The so-called unified settlement means that the expenditure or income of multiple businesses is summarized to obtain a final summary result, and then the expenditure or income of the vehicle is settled directly based on the summary result. The expenditure or income of the vehicle is determined by calling the consumption processing system to calculate the expenditure and income of the vehicle in different businesses.
[0087] In this way, the present application can query, count and record the vehicle information and consumption income of the vehicle when the vehicle enters the charging station and uses consumption-related services in the station, and perform unified settlement before the vehicle leaves the charging station based on the recorded data and related statistical data, thereby avoiding the complex situation where multiple settlements are required for multiple services within charging, effectively improving the settlement efficiency of the charging station, and at the same time supporting two-way settlement of expenditures and income, which can effectively support the application scenarios of V2G.
[0088] like Figure 2 As shown, in some embodiments, before step 01, the method further includes:
[0089] 0111: Get the electronic wallet tag of the vehicle;
[0090] 0112: When the electronic wallet tag exists, the electronic wallet can be used for settlement of expenditures or income, and the electronic wallet is successfully bound to the payment account, it is determined that the electronic payment channel exists.
[0091] Specifically, with regard to the method of confirming the electronic payment channel, in some examples, what is mainly confirmed is the third-party electronic wallet account corresponding to the vehicle. In order to confirm the electronic payment channel, the electronic tag of the third-party electronic wallet corresponding to the vehicle is first obtained on a third-party platform through the Internet. The electronic tag is generally used to indicate the account information and account status of the electronic wallet.
[0092] When the electronic wallet tag corresponding to the vehicle is obtained, the electronic wallet account status indicated in the electronic wallet tag is detected. If it is detected that the electronic wallet can be used for settlement of expenditures or income in the current state, that is, the current state of the electronic wallet is normal, the payment path of the third-party electronic wallet is further confirmed. In particular, while detecting the electronic wallet account status indicated in the electronic wallet tag, the user can also be asked to confirm whether he agrees to use the third-party electronic wallet for settlement of expenditures and income in the charging station. If the user agrees to use the third-party electronic wallet for settlement of expenditures and income in the charging station, it is also determined that the electronic wallet can be used for settlement of expenditures or income in the current state, that is, the current state of the electronic wallet is normal, and the payment path of the third-party electronic wallet is further confirmed.
[0093] The payment path of a third-party electronic wallet is generally a payment account bound to the third-party electronic wallet. The payment account can be a bank account or other mobile payment account. If it is detected that a third-party electronic wallet is bound to a valid payment account, it can be confirmed that the vehicle currently has an electronic payment channel. In particular, while detecting the existence of the payment account, the user can also be asked to confirm whether he agrees to bind the payment account to the third-party electronic wallet. If the user agrees and successfully binds the payment account, it is also determined that the third-party electronic wallet is bound to a valid payment account, thereby confirming that the vehicle currently has an electronic payment channel.
[0094] In this way, the present application can determine the electronic payment channel corresponding to the vehicle by querying and confirming the electronic wallet and payment account.
[0095] like Figure 2 As shown, in some embodiments, the consumption processing method of the embodiment of the present application further includes:
[0096] 0113: When the electronic wallet tag does not exist, or when the electronic wallet cannot be used for settlement of expenditures and income, or when the electronic wallet cannot be bound to a payment account, it is determined that the electronic payment channel does not exist.
[0097] Specifically, in the above-mentioned process of confirming the electronic payment channel, if the electronic wallet tag of the third-party electronic wallet is not detected, it means that the vehicle cannot adapt to the statistics and settlement process of the consumption processing system. Such a vehicle can still use the various services of the charging station, but cannot settle expenses or income through the consumption processing system provided by this application.
[0098] In addition, if it is detected through the electronic wallet tag that the account status of the current electronic wallet is abnormal and the settlement of expenditures or income cannot be performed normally, or the user does not agree to use a third-party electronic wallet for the settlement of expenditures and income at the charging station, it also means that the vehicle cannot adapt to the statistics and settlement process of the consumption processing system. Such a vehicle can still use the various services of the charging station, but cannot settle expenditures or income through the consumption processing system provided by this application.
[0099] In addition, if it is found through the detection of the payment account binding electronic wallet that the current electronic wallet has no valid bound payment account, or based on this situation, the user still does not agree to bind a valid payment account or the binding of the payment account fails, and the electronic wallet does not have a valid bound payment account at this time, it also means that the vehicle cannot adapt to the statistics and settlement process of the consumption processing system. Such a vehicle can still use the various services of the charging station, but cannot settle expenses or income through the consumption processing system provided by this application.
[0100] In order to reduce the system load, such vehicles are directly identified as having no electronic payment channels and are excluded from the settlement scope of the consumption processing system, so that when the vehicle leaves the charging station to settle various business transactions, the non-consumption processing system can be used for settlement, thereby achieving rapid classification of the vehicle.
[0101] like Figure 2 As shown, in some embodiments, step 01 includes:
[0102] 011: Obtain vehicle information of the vehicle in the presence of an electronic payment channel;
[0103] 012: When the vehicle information of the vehicle is obtained, the vehicle information is updated according to the current vehicle information of the vehicle.
[0104] Specifically, in order to facilitate the settlement process of various services in the charging station, when the vehicle enters the charging station, it is necessary to establish a vehicle information file for the vehicle in the consumption processing system. If the vehicle does not have a relevant electronic payment channel, there is no need to use the consumption processing system for settlement. Therefore, before obtaining the vehicle information, the electronic payment channel of the vehicle is preferentially determined. If the channel exists, the vehicle information corresponding to the vehicle is further obtained from the consumption processing system.
[0105] In some examples, obtaining vehicle information corresponding to the vehicle can be achieved in the following manner: first, the vehicle license plate number, vehicle identification number (VIN code), vehicle model and other information are identified through an image recognition device, and then the stored information is queried in the consumer processing system of the consumer processing system based on the identified information, and the vehicle information entry corresponding to the above information is called.
[0106] According to the query method as described above, if a vehicle information entry corresponding to the above information is found, that is, the vehicle has been recorded in the consumption processing system, then the license plate number, vehicle identification number (VIN code), vehicle model and other information identified when the vehicle enters the station will be updated to the queried vehicle information entry.
[0107] The purpose of the above process of updating vehicle information entries is to establish unique information entries and corresponding relationships for each different vehicle to ensure the accuracy and convenience of the subsequent settlement process.
[0108] In this way, the present application can query, confirm and update the vehicle information and electronic payment channels of the vehicle within the consumption processing system when the vehicle enters the charging station.
[0109] like Figure 2 As shown, in some embodiments, step 01 also includes:
[0110] 013: In the case where the vehicle information of the vehicle is not obtained, the current vehicle information and electronic payment channel of the vehicle are initialized and stored in the consumption processing system.
[0111] Specifically, based on the above implementation method, if no vehicle information entry corresponding to the above information is found in the consumption processing system, that is, the vehicle is not recorded in the consumption processing system, then a vehicle information entry corresponding to the vehicle is established in the consumption processing system according to the identified license plate number, vehicle identification number (VIN code), vehicle model and other information, so that subsequent expenditure or income statistics data can be stored in correspondence with the vehicle information, further facilitating the unified settlement of expenditures or income.
[0112] In this way, the present application can add vehicle information to the consumption processing system to facilitate the subsequent settlement process when the vehicle information is not obtained when the vehicle enters the charging station.
[0113] In this way, the present application can also determine that there is no electronic payment channel for the vehicle in a variety of other situations, so as to quickly classify the vehicle during subsequent settlement.
[0114] like Figure 3 As shown, in some embodiments, step 02 includes:
[0115] 021: Obtain the charging and discharging amount of the vehicle according to the vehicle information;
[0116] 022: Determine first expenditure information according to the charging amount;
[0117] 023: Determine first revenue information according to the discharge amount.
[0118] Specifically, when a vehicle uses the service in a charging station, the main expenses and income come from the electricity costs required for charging and the discharge income required for discharging. Therefore, the expenses or income generated by the service are directly related to the electricity output or received by the vehicle in the charging station.
[0119] In some examples, if the vehicle information of the vehicle can be obtained in the consumer processing system:
[0120] First, the power control module in the consumer processing system controls the amount of power transmitted or received to the vehicle, and then the power control module feeds back the amount of power transmitted or received to the consumer processing system.
[0121] Next, the consumption processing system directly calls the power transmission and power reception obtained from the power control module, and combines the current electricity price to settle the expenses of the vehicle in the power station for charging and the income obtained from the reverse power transmission of the vehicle in the power station. The determined expenses or income are stored in the consumption processing system in correspondence with the vehicle information, thus completing the statistics of the vehicle's main expenses and income in the charging station.
[0122] In other examples, if the electronic payment channel of the vehicle does not exist or the vehicle information of the vehicle cannot be obtained normally:
[0123] First, the power control module in the consumer processing system controls the amount of power transmitted or received to the vehicle, and then the power control module feeds back the amount of power transmitted or received to the consumer processing system.
[0124] Next, the consumption processing system directly calls the acquired power transmission and power reception to the vehicle from the power control module, and, in combination with the current electricity price, settles the expenses of the vehicle for charging in the power station and the income obtained from the vehicle's reverse power transmission in the power station, and then stores the acquired expenditure or income in a temporary storage area in the consumption processing system, so that the expenditure information and income information can be called up during settlement and the expenditure or income can be settled through methods other than the method provided in the implementation mode of the present application.
[0125] In this way, the present application can obtain the expenditure or income generated by the vehicle due to power transmission in the charging station by counting the power transmission amounts in different directions.
[0126] In some embodiments, step 02 further includes:
[0127] When the value of at least one of the first expenditure information and the first income information is not 0, or the parking time of the vehicle is greater than the preset time limit, a first signal is generated, and the first signal is used to indicate that there are expenses or incomes to be settled for the vehicle in the charging station;
[0128] In the case where the vehicle has an electronic payment channel, second income information generated by the user pre-depositing fees through the electronic payment channel is obtained.
[0129] Specifically, in order to avoid omissions in the settlement of expenditures or revenues, when a vehicle uses services in a charging station, as long as there is an expenditure amount or a revenue amount in a certain business, it is necessary to mark the vehicle by generating a marking signal to indicate that the vehicle currently has a business to be settled. For example, a vehicle incurs an expenditure of 100 yuan when charging in a charging station. At this time, a first signal is generated in the consumption processing system, and the first signal is saved in the consumption processing system to indicate that the vehicle currently has a business to be settled. For another example, a vehicle incurs an expenditure of 100 yuan when charging in a charging station, and also generates a revenue of 100 yuan when discharging to the power grid. At this time, a first signal will also be generated in the consumption processing system to indicate that the vehicle currently has a business to be settled. That is, when a vehicle uses related services in a charging station, even if the expenditure and revenue are generally balanced, a single business still needs to be settled, so it is still necessary to generate a marking signal to indicate that the current vehicle has a business to be settled.
[0130] In addition, in addition to the expenses for charging services and the income from receiving electricity services, charging stations also incur parking fees when vehicles stay within the scope of the charging station. However, the specific value of the parking expenses can only be settled when the vehicle leaves the charging station. Therefore, in order to be able to mark the settlement of parking expenses when the vehicle uses the service in the charging station, the parking time is counted. If the length of time the vehicle stays in the charging station exceeds the free time limit, it will also trigger the generation of the above-mentioned marking signal, that is, there is at least a state where the parking fee is to be settled.
[0131] At the same time, in order to facilitate users' use of charging stations, the consumption processing system also provides the function of users pre-depositing fees through the vehicle's electronic payment channel. The user's pre-deposited fees are a special kind of income that will not be cleared at will during the settlement process. After the user pre-deposits fees through the electronic payment channel, the consumption processing system will save the pre-deposited fee information and the pre-deposited amount information as the second income in the consumption processing system. When the vehicle enters the charging station to use the service, the consumption processing system calls the second income from the consumption processing system to prepare data for the subsequent settlement process.
[0132] In this way, the present application can also save the status of pending settlement services through the first signal, and can also save the user's pre-deposited fee status through the second revenue information, so as to quickly classify the vehicle's settlement method during settlement.
[0133] like Figure 4 As shown, in some embodiments, step 03 includes:
[0134] 031: When an electronic payment channel of the vehicle exists, obtaining vehicle information of the vehicle according to the first signal;
[0135] 032: Determine comprehensive expenditure and income information according to the vehicle information, the first expenditure information, the first income information and the parking time of the vehicle;
[0136] 033: Settle the vehicle’s expenses or income at the charging station based on the comprehensive expenditure and income information.
[0137] Specifically, when the vehicle is about to leave the charging station, the consumption processing system begins to settle the expenses or income generated by the vehicle's various businesses in the charging station. First, it is necessary to confirm whether the vehicle has an electronic payment channel to determine whether the vehicle needs to settle expenses or income through the consumption processing system.
[0138] Then, when it is detected that the vehicle has an electronic payment channel, a marking signal for marking that the vehicle has pending settlement transactions is detected for the purpose of simplifying the subsequent settlement process. In some examples, a first signal corresponding to the current vehicle is detected and retrieved from the consumption processing system. If the first signal exists, it indicates that the current vehicle has pending settlement transactions in the charging station.
[0139] In this case, the vehicle information corresponding to the vehicle is called from the consumption processing system. If the vehicle information can be called, it is determined that there is a record entry for the vehicle in the consumption processing system, and it also has an electronic payment channel that can cooperate with the consumption processing system. That is, it is determined that the settlement of expenditures and income can be carried out normally through the consumption processing system.
[0140] Next, the expenses or income generated by the services used by the vehicle in the charging station are settled. In order to achieve unified settlement of expenses or income, at least the expenses of charging, the income of discharging, and the expenses related to parking time are combined to calculate the expenses or income of the vehicle in the charging station, that is, the comprehensive expenses and income information.
[0141] Finally, based on the expenditure amount or income amount shown in the comprehensive expenditure and income information, the expenditure amount is charged to the user or the income amount is returned to complete the settlement of various transactions of the vehicle in the charging station.
[0142] In this way, this application can coordinate and summarize the expenses and income of various businesses of the vehicle in the charging station according to the recorded vehicle information and payment method information, so as to quickly complete the unified settlement of various expenses and income and improve the user experience of the charging station.
[0143] In addition, based on the above implementation, if it is detected that the vehicle does not have an electronic payment channel, or the vehicle information entry corresponding to the vehicle is not obtained in the consumption processing system, the vehicle cannot cooperate with the consumption processing system to automatically settle various expenditures and benefits. In the case where the vehicle information entry corresponding to the vehicle is not obtained in the consumption processing system, it may be that the system loses information during the vehicle's use of services in the charging station, or there is an error in the identification of relevant information when the vehicle enters the station, resulting in no vehicle information entry corresponding to the vehicle in the system. In the above case, in order not to affect the normal settlement and departure process of the vehicle, settlement should be carried out by means other than the consumption processing system provided by this application, such as manually calculating expenditures and benefits, and settling expenditures and benefits through cash, bank cards, mobile payments, etc. In this way, when the vehicle information cannot be obtained or the vehicle does not have an electronic payment channel, various expenditures and benefits can be counted and settled through channels other than the consumption processing system in the above implementation, so as to avoid the situation where the vehicle cannot be settled normally when leaving the station due to the lack of electronic payment channels or information loss.
[0144] Furthermore, based on the above implementation, if the consumption processing system does not obtain a marking signal corresponding to the vehicle to be settled, it means that the vehicle did not use any service in the charging station, or each service used did not generate any expenditure or income. In this case, there is no need to settle the expenditure or income of the vehicle, and the settlement process can be terminated directly. This can effectively reduce the complexity of the settlement process.
[0145] In some embodiments, step 032 includes:
[0146] Determining second expenditure information of the vehicle according to the parking duration;
[0147] The comprehensive expenditure and income information is determined based on the first expenditure information, the first income information and the second expenditure information.
[0148] Specifically, based on the above implementation method, before comprehensively aggregating and calculating the comprehensive expenditure and income information, it is necessary to first calculate and determine the expenditure information related to the parking duration based on the parking duration and the corresponding relationship between the parking duration and the parking expenditure.
[0149] Then, the first expenditure corresponding to charging, the first benefit corresponding to discharging, and the second expenditure corresponding to the parking time are directly added together to achieve overall summary. Generally, the income is positive and the expenditure is negative, and the amount information representing the income or expenditure is obtained, that is, the comprehensive expenditure and income information.
[0150] In this way, the present application can also support the statistics of the expenses corresponding to the parking time of vehicles in the charging station, and coordinate and summarize the expenses corresponding to parking with the expenses and income generated by power transmission, so that the consumption processing system can make a unified settlement of the vehicle's expenses and income based on the results of the coordination and summary.
[0151] In some embodiments, step 034 includes:
[0152] When the comprehensive expenditure and income information is income information, or the value of the comprehensive expenditure and income information is 0,
[0153] The prepaid expenses of the vehicle are updated according to the comprehensive expenditure and income information and the second income information.
[0154] Specifically, since each business involves both expenditure and income, the comprehensive expenditure and income information obtained may be the expenditure amount, the income amount, or 0, which means that the income and expenditure are balanced. In order to simplify the settlement process, improve settlement efficiency and user experience, when the comprehensive expenditure and income information obtained is the income amount or the value is 0, which means that the income and expenditure are balanced, the comprehensive expenditure and income information is directly combined with the pre-deposited expenses corresponding to the vehicle to obtain a new pre-deposited expense amount.
[0155] For example, in some examples, the user's pre-deposit fee is 10 yuan, and the comprehensive expenditure and income information of this time is a profit of 15 yuan. The settlement process is: update the pre-deposit fee to 25 yuan and terminate the settlement process.
[0156] In this way, when the result of the overall aggregation is profit, this application can directly merge the profit part into the pre-deposited fees corresponding to the vehicle, and quickly end the settlement process.
[0157] In some embodiments, step 033 further includes:
[0158] Determine the preferred payment method for the settlement process when the comprehensive expenditure and income information is expenditure information;
[0159] When the preferred payment method is the preset payment method, the comprehensive expenditure and income information will be sent to the third-party platform where the preset payment method is located to realize payment.
[0160] Specifically, when the comprehensive expenditure and income information obtained is the expenditure amount, in order to improve the user experience and provide users with more payment method options, in some examples, the consumption processing system gives priority to confirming to the user the payment method to be preferred in the current settlement process. Generally, it confirms to the user that third-party electronic wallet payment or pre-deposited fees are preferred for payment.
[0161] If the user confirms that he prefers to use a third-party electronic wallet for payment, the comprehensive expenditure and income information obtained will be sent directly to the settlement platform where the third-party electronic wallet is located for payment settlement, where the payment amount is equal to the comprehensive expenditure and income information (expenditure amount), that is, the user chooses to pay the full amount of the current expenditure first without using the pre-deposited fees.
[0162] In this way, when the result of the overall summary is expenditure, and when the user chooses to give priority to the electronic wallet settlement method, this application can directly send the total expenditure amount to the third-party platform where the electronic wallet is located to initiate payment, providing the user with the option of directly paying the total expenditure amount at that time, thereby improving the user experience.
[0163] In some embodiments, step 033 further includes:
[0164] When the preferred payment method is prepaid fees, the planned balance of the vehicle is determined based on the comprehensive expenditure income information and the second income information;
[0165] When the planned balance is less than 0, the comprehensive expenditure and income information will be sent to the third-party platform where the preset payment method is located to realize payment, where the payment amount is the value of the comprehensive expenditure and income information.
[0166] Specifically, based on the above implementation, if the user confirms that the pre-deposited fee is preferred for payment, since the relationship between the pre-deposited fee and the comprehensive expenditure and income information is uncertain, it is necessary to perform a withholding fee calculation to determine whether the pre-deposited fee is sufficient to pay the current expenditure amount. The withholding fee calculation is to directly add the pre-deposited fee to the comprehensive expenditure and income information to obtain a planned balance.
[0167] In the above case, if the value of the planned balance obtained is less than 0, it means that the pre-deposited fees are not enough to pay for the vehicle's current expenses. At this time, it is necessary to forcibly adopt a non-preferred payment method. In some examples, when the value of the planned balance obtained is less than 0, the expenditure amount corresponding to the comprehensive expenditure and income information can be sent directly to the platform where the third-party electronic wallet is located for payment settlement, or the absolute value of the planned balance obtained can be sent to the platform where the third-party electronic wallet is located for payment settlement. That is, the settlement of expenses can be achieved in two ways: full payment through the electronic wallet or supplementary payment of the insufficient pre-deposited fees.
[0168] In this way, when the result of the overall aggregation is expenditure, and the user has not chosen to give priority to the electronic wallet settlement method, the present application can first withhold fees based on the pre-deposited fees corresponding to the vehicle and the total expenditure amount of the time. If the result of the pre-deposit fees is that the pre-deposit fees are insufficient to pay the total expenditure amount of the time, the total expenditure amount of the time will be paid through the electronic wallet.
[0169] In some embodiments, step 033 further includes:
[0170] When the planned balance is greater than or equal to 0, the prepaid fee of the vehicle is updated according to the planned balance.
[0171] Specifically, based on the above implementation, if the user confirms that the pre-deposited fee is preferred for payment, and the value of the planned balance is greater than or equal to 0, it means that the pre-deposited fee can complete the payment process for the vehicle's current expenditure. In this case, the calculated planned balance is directly updated to the new pre-deposited fee value, and the pre-deposited fee is used to pay the vehicle's current expenditure at the charging station.
[0172] In this way, when the result of the overall aggregation is expenditure, and the user has not chosen to give priority to the electronic wallet settlement method, the payment can be made based on the pre-deposited fees corresponding to the vehicle and the total expenditure amount of the time.
[0173] like Figure 5 As shown, in some embodiments, the consumption processing method further includes:
[0174] 04: Reset the first expenditure information, the first income information and the second expenditure information to zero;
[0175] 05: Send a release command to the blocking device of the charging station to allow the vehicle to leave the charging station.
[0176] Specifically, in order to ensure that the amount of data stored during the operation of the consumption processing system is within a controllable range, and at the same time ensure the accuracy of the expenditure or income information generated by the same vehicle the next time it goes to the charging station to use the service, after the vehicle completes the settlement, the expenditure information generated by the vehicle at the charging station and the income information other than the pre-deposited fees are reset to zero. In this way, the next time the vehicle goes to the charging station to use the service, the initial value of each expenditure information and income information will still be 0, and will not cause any errors.
[0177] In addition, after the settlement of expenditures and revenues is completed, all events of the vehicle in the charging station are completed. At this time, the consumption processing system sends a release instruction to the blocking device set at the exit of the charging station, so that the blocking device releases the blockage to allow the vehicle to leave the charging station.
[0178] In this way, after the settlement process is completed, this application will reset all expenditure and income information to zero, so that the vehicle can be re-counted the next time it goes to the charging station to use related services, and then control the blocking devices such as blocking bars and blocking curtains at the exit of the charging station to remove the blockage so that the vehicle can leave the charging station.
[0179] like Figure 6 As shown, the present application provides a consumption processing system for a vehicle charging station, comprising:
[0180] An information acquisition module, used to acquire vehicle information of a vehicle;
[0181] The information statistics module is used to obtain the expenditure information and income information of the vehicle based on the vehicle information;
[0182] The settlement module is used to make a unified settlement of the expenditure or income of the vehicle in the charging station based on the expenditure information and income information.
[0183] Specifically, the process of a vehicle using a V2G charging station generally includes entering the station, charging / discharging, and exiting the station. In order to make the process of the vehicle using related services in the charging station smoother, and in view of the characteristics that users obtain income when the V2G charging station transmits electricity to the power grid and users spend money when charging from the power grid, the present application provides a consumption processing system, which is mainly divided into three parts: an information acquisition module, an information statistics module, and a settlement module. The three parts are closely connected through a communication network, and can access and call vehicle-related data at any time as needed.
[0184] The information acquisition module is mainly used to query relevant information of the vehicle when it enters the charging station, such as the vehicle's license plate number, vehicle identification code (VIN code), etc., so as to match the identified vehicle when the information is called in the system to avoid errors in the use and settlement of the business.
[0185] The information statistics module is mainly aimed at counting the expenses or income generated by the relevant services when the vehicle uses the relevant services in the charging station. In order to ensure that the statistical expenses or income correspond to the vehicles using the relevant services, before the statistics of expenses and income are calculated, it is necessary to first call the vehicle information queried by the information query module, and associate the statistical expenses and income with the vehicle information, so as to facilitate the subsequent unified settlement of the vehicle's current expenses or income in the charging station.
[0186] The settlement module is mainly used to settle the expenditure or income of the vehicle when it leaves the charging station. The so-called unified settlement means that the expenditure or income of multiple businesses is summarized to obtain a final summary result, and then the expenditure or income of the vehicle is settled directly based on the summary result. The expenditure or income of the vehicle is determined by calling the information statistics module to calculate the expenditure and income of the vehicle in different businesses.
[0187] In this way, the present application queries, counts and records the consumption and income of the vehicle when the vehicle enters the charging station and uses consumption-related services in the station through the setting of the information statistics module, and the settlement module performs unified settlement based on the recorded data and related statistical data before the vehicle leaves the charging station, thereby avoiding the complex situation that multiple settlements are required for multiple services in charging, effectively improving the settlement efficiency of the charging station, and at the same time supporting two-way settlement of expenditures and income, which can effectively support the application scenarios of V2G.
[0188] like Figure 6 As shown, in some embodiments, the consumption processing system further includes:
[0189] A charging station module, used to charge or receive power from a vehicle;
[0190] The power control module is used to control the charging station module to charge the vehicle or receive power from the vehicle.
[0191] Specifically, a plurality of charging station modules may be provided in the consumption processing system. The charging station modules are mainly composed of charging devices that support V2G technology and can realize bidirectional power transmission, such as charging piles, charging boxes, etc., which can realize charging or receiving power from vehicles through electrical connection with electric vehicles. Under V2G technology, charging piles, charging boxes and other charging devices are generally directly connected to the power grid where the charging station is located. The process of charging the vehicle is to directly transmit the power from the power grid to the vehicle after transformation and rectification. The process of receiving power from the vehicle is to obtain the current from the vehicle and then transmit it to the power grid after boosting and rectification. In some examples, in order to facilitate the cooperation with the information query module, information statistics module and settlement module in the consumption processing system to provide convenience to users, the charging station corresponding to each charging station module is settled by the above three modules for related business, so that users can realize data intercommunication in the settlement process at different charging stations, thereby improving the user experience.
[0192] In order to ensure the consistency of power transmission direction and improve the stability and safety of the power transmission process, the bidirectional power transmission of each charging station module in the system is controlled by the power control module. When the user chooses to charge the vehicle, the power control module controls the corresponding charging device to output power to the vehicle, while ensuring the stability of the direction and magnitude of the current. Conversely, when the user chooses to receive power from the vehicle, the power control module controls the corresponding charging device to receive power from the vehicle's battery, while ensuring the stability of the direction and magnitude of the current.
[0193] In this way, the present application can also realize direct two-way power exchange with the vehicle and control the current power transmission direction.
[0194] like Figure 6As shown, in some embodiments, the system includes a first communication network and a second communication network, the first communication network includes a charging station module, an information query module, an information statistics module, a settlement module and a power control module, and the second communication network includes a charging station module, an information query module, an information statistics module, a settlement module and a power control module.
[0195] Specifically, in order to achieve information exchange between modules within the system and the stability of business operations, each module forms two groups of communication networks with the same structure. The two groups of communication networks are connected to different ports at the same module but have exactly the same functions. The two groups of communication networks run simultaneously and back up each other.
[0196] In some examples, the charging station module, the information query module, the information statistics module, the settlement module and the power control module are connected to the communication network A ( Figure 6 The thick solid line in the figure) and the communication network B ( Figure 6 The thin solid line in the figure), wherein communication network A is connected to port 1 of each module, and communication network B is connected to port 2 of each module, and the connection relationship between each module in communication network A and communication network B is exactly the same. When information transmission occurs between each module, information transmission is initiated in communication network A and communication network B at the same time. When the receiving end receives the transmitted information, if it is found that the currently received information is new information by comparing the timestamp with the file header information, the corresponding instruction execution or information storage and other services are performed. If it is found that the currently received information has been received and executed by comparing the timestamp with the file header information, the information is discarded. In this way, it can be ensured that in the event that one of the two communication networks fails, the stable operation of the system can still be guaranteed by only one communication network. In some examples, while ensuring operation, it is also possible to feedback network failures by feeding back failure information to the monitor, so that the monitor can maintain and repair the network.
[0197] In this way, the present application constructs two groups of communication networks that can back up each other between the component modules of the system, so that the system can still operate normally when one of the communication networks fails.
[0198] The embodiments of the present application also relate to a computer-readable storage medium, which stores a computer program. When the computer program is executed by one or more processors, the consumption processing method in the above embodiments is implemented.
