[0028] The embodiments of the present application provide a charging pile charging control system compatible with a credit card, such as Figure 1As shown, the system includes a card reader module, a charging pile module, and a control module. The card reader module is mounted on the charging equipment's casing and is used by users to attach their cards for card reading. The charging pile module is located inside the charging equipment and provides power through a charging interface on the charging equipment's casing. Users connect their vehicle's charging port to the charging interface on the casing for charging. The control module can be located outside the charging equipment and can communicate with the card reader module and the charging pile module. After a vehicle is connected to the charging equipment, the charging equipment can obtain vehicle data, including destination requirements, historical driving speed, and charging power, after user authorization.

[0029] The charging pile module and the card reader module use RS232 serial communication with a baud rate of 115200, 8 data bits, and no parity; the communication protocol is Marshall protocol.

[0030] This application provides a charging control method for charging stations compatible with credit cards, such as... Figure 2 As shown, the method provided in this embodiment is executed by a control module, which can be a server or a terminal device. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication. This embodiment does not impose any limitations on this connection. The method includes steps S201-S203, wherein: S201. Receive card reading information and verification results sent by the card reader module. The card reading information includes the card type.

[0031] Specifically, the user activates the card reader by clicking on the interactive interface of the card reader module. The user then swipes the card, and the card reader module identifies the card information, including the card type and card number.

[0032] When the card type is a credit card, the card reader module sends the card number information to the corresponding bank for pre-authorization verification, and then receives the verification result from the bank. If the verification result is unsuccessful, the card reader module stops the service and displays a "Verification failed, transaction canceled" message on the interactive interface.

[0033] When the card type is an RFID card, the card number information is sent to the charging pile module by the card reader module, the card number information is sent to the third-party platform by the charging pile module, the third-party platform as a charging management system can be configured on the control module, the third-party platform verifies the card number information, and sends the verification result to the card reader module. When the verification result is not passed, the card reader module is controlled to stop the service, and a prompt message of "verification failed, transaction canceled" is displayed through the interactive interface.

[0034] S202, when the card type is a credit card and the verification result is passed, the charging pile module is controlled to charge the current vehicle, and the charging amount is determined, the charging amount is sent to the card reader module, so that the card reader module completes the transaction according to the charging amount and the bank corresponding to the credit card.

[0035] Specifically, the charging pile module is controlled to charge the current vehicle, and the charging period (the period formed by the start charging time and the end charging time) and the charging power are recorded in real time. During the charging process, the charging pile module can calculate the charging amount by the built-in algorithm, or the control module can calculate the charging amount by the built-in algorithm, and the embodiment is not limited. If the control module calculates the charging amount, the control module sends the charging amount to the charging pile module after the charging is completed.

[0036] During the charging process, the power amount of the charging power can be calculated in real time, the time period from the charging start time to the current time is taken as the charging period, the power amount of this period is calculated, and the interactive interface of the card reader module is displayed in real time.

[0037] After the charging is completed, the final charging amount is calculated, the charging amount includes the power amount and the service fee amount, and if the user does not disconnect the charging interface of the current vehicle from the charging pile module after the charging is completed, an idle fee will be generated additionally after the idle time threshold corresponding period, and the idle fee, the power amount and the service fee amount are superimposed to obtain the charging amount. After the user disconnects the charging interface of the current vehicle from the charging pile module, the charging pile module sends the charging amount to the card reader module, the card reader module and the bank corresponding to the credit card complete the transaction settlement, and the transaction is completed.

[0038] S203, when the card type is an RFID card and the verification result is passed, the charging pile module is controlled to charge the current vehicle, and the charging amount is determined, and the transaction is completed according to the charging amount and the RFID card.

[0039] Specifically, the credit card and the RFID card determine the charging amount in different processes, but the value calculation process of the charging amount is the same. The charging amount can be calculated by the charging pile module and sent to the third-party platform, or calculated by the control module and sent to the third-party platform, or calculated by the third-party platform and further completed by the third-party platform. At the same time, the charging pile module sends the card reader module to close the session, the third-party platform settles the transaction, deducts the charging amount from the RFID card, and the transaction is completed.

[0040] The embodiment receives the card reading information and verification result of the card reader module, and after verification, distinguishes the credit card (completed transaction by the joint bank) and the RFID card (completed transaction by the background), controls the charging of the charging pile and determines the charging amount; by compatible with the two mainstream payment carriers of credit card and RFID card, it breaks through the limitation of the single payment mode of the traditional charging pile, not only meets the convenience of users using daily financial cards (credit cards), but also retains the advantages of fast transactions of special RFID cards, and improves the payment compatibility and user flexibility of the charging pile.

[0041] In one possible implementation of the embodiment of the application, the charging amount is determined, comprising: Obtaining the charging demand input by the user through the interactive interface of the card reader module, the charging demand including full charging and mileage charging; When the charging demand type is mileage charging, obtaining the destination demand and historical driving data of the user, real-time estimating the charging information based on the destination demand and the historical driving data, and displaying the charging information on the interactive interface; After receiving the charging completion signal, determining the electricity amount based on the electricity charging rule, and determining the service fee amount based on the service charging rule; Calculating the sum of the electricity amount and the service fee amount as the charging amount.

[0042] In the embodiment, the charging demand represents the specific requirement of the user for charging, the full charging represents charging the vehicle battery to 100% or a pre-set threshold value representing full charging, and the mileage charging represents charging to an amount of electricity that can meet the destination demand. If the user selects the mileage charging, the interactive interface automatically jumps to the input interface, and the user can input the destination demand. The format of the destination demand can be the target mileage or the destination location. If the user inputs the destination location, the system automatically calculates the target mileage from the current location to the destination. The target mileage represents the minimum driving distance that the user hopes to support after charging.

[0043] The historical driving data includes driving records of the user driving the vehicle (matched through license plate recognition or vehicle BMS system) in the past period of time, including driving mileage, corresponding power consumption, driving speed, road conditions and other data. Based on the destination demand and the historical driving data, the minimum power required to drive to the destination is estimated as the target power. If the user's charging demand is to stop when full, the target power is the maximum capacity of the battery.

[0044] After determining the user's charging demand, the target power can be determined. The charging pile module is provided with a metering module for receiving the rated charging power of the current vehicle and the real-time feedback of the remaining power information of the BMS, and the difference between the remaining power information before charging starts and the target power is calculated as the total amount to be charged. The metering module is also used to real-time statistics of the amount of electricity charged and the charging time. During the charging process, the difference between the total amount to be charged and the amount of electricity charged is calculated as the amount to be charged, and the ratio of the amount to be charged to the rated charging power is calculated as the estimated remaining charging time, and the current power amount is calculated through the amount of electricity charged and / or the charging time. The charging information is the charging parameter estimated based on the destination demand and the historical data, including the remaining power information at the current time, the amount to be charged, the remaining charging time, the amount of electricity charged, etc. The specific charging information can be set according to the actual demand, and the embodiment is not limited. The charging information is dynamically displayed on the interactive interface of the card reader module.

[0045] When it is monitored that the charging interface of the current vehicle is disconnected from the charging pile module, the charging pile module sends a charging completion signal to the control module to obtain the total charging period (actual charging period) and the total charging power (actual total charging power), and determines the power amount based on the total charging period, the total charging power and the power charging rule.

[0046] The service charge rule is divided into two kinds of charging by degree and charging by single, and the service charge amount is calculated through the service charge rule supported by the charging pile module. If the charging pile module supports charging by degree, the product of the charging amount per degree and the total charging power is calculated as the service charge amount. For vehicles with small total charging power, charging by degree is more preferential, and for vehicles with large total charging power, charging by single is more preferential.

[0047] The embodiment allows the user to independently select the charging demand, avoiding the problem of power waste or insufficient power caused by one-size-fits-all charging mode; the charging information estimation during mileage power compensation allows the user to know the key information such as the amount of electricity and the time in advance, improving the transparency of consumption; the amount is calculated based on the power and service double rules, which covers the cost of electric energy and guarantees the service income of the charging pile operator, achieving the balance between user demand and operating cost.

[0048] In one possible implementation of the embodiment, the charging information is estimated in real time based on the destination demand and the historical driving data, including: constructing a driving speed curve and a power consumption speed curve based on historical driving data; aligning the driving speed curve and the power consumption speed curve in time, determining a driving speed range of the driving speed curve, calculating an average value of a plurality of power consumption speeds corresponding to each driving speed sampling point in the driving speed range, and taking each driving speed sampling point and the corresponding average value of power consumption speed in the driving speed range as a driving power consumption mapping relationship; determining a maximum power consumption per unit distance from the driving power consumption mapping relationship, and determining a target power based on the destination requirement and the maximum power consumption per unit distance; obtaining real-time residual power information, and generating charging information based on the residual power information and the target power.

[0049] In this embodiment, the driving speed curve is a continuous curve with time as the horizontal axis and instantaneous driving speed as the vertical axis, reflecting the trend of the speed of the vehicle changing with time in the historical driving process. The power consumption speed curve is a continuous curve with time as the horizontal axis and instantaneous power consumption speed as the vertical axis, reflecting the trend of the power consumption per unit time changing with time in the historical driving process. The time stamp alignment means that the time axes of the driving speed curve and the power consumption speed curve are completely synchronized (i.e., the same time point corresponds to a unique speed value and a power consumption speed value), ensuring the accuracy of the correlation analysis of the two.

[0050] The minimum and maximum values of the driving speed are determined from the driving speed curve, and the range formed thereby is taken as the driving speed range. Sampling is performed based on a preset step size to obtain a plurality of driving speed sampling points. The driving power consumption mapping relationship represents a one-to-one correspondence between the driving speed sampling points and the corresponding average power consumption speed, such as 50 km / h→0.0025 kWh / s, reflecting the average power consumption level at different speeds.

[0051] The power consumption speed is converted into power consumption per unit distance, including: the unit of power consumption speed is kWh / s (power consumption per second), the unit of driving speed is km / h (driving distance per hour), and the unit is unified as 1 km / h=1 / 3600 km / s. Power consumption per unit distance (kWh / km)=power consumption speed (kWh / s) / driving speed (km / s)=power consumption speed×3600 / driving speed. For each sampling point in the driving power consumption mapping relationship table, the power consumption per unit distance is calculated according to the above formula, and the power consumption per unit distance corresponding to each driving speed sampling point is obtained. The maximum value of the power consumption per unit distance is taken, and the maximum power consumption per unit distance reflects the most power-consuming unit distance energy consumption level of the vehicle in the historical driving, which is used to reserve redundant power to ensure reaching the destination.

[0052] The target power is represented as the total power required to meet the destination requirement, and the calculation formula is target mileage×maximum power consumption per unit distance.

[0053] The embodiment mines the correlation between speed and power consumption through historical driving data, calculates the target power consumption by maximum power consumption per unit distance, can reserve sufficient redundant power consumption, avoids the problem of insufficient power consumption caused by road conditions and driving habits, and ensures that the user can smoothly reach the destination; at the same time, accurate charging information is generated based on the actual remaining power, helping the user to reasonably plan the charging time and cost, and improving the accuracy and reliability of the charging service.

[0054] In one possible implementation of the embodiment of the application, the amount of power is determined based on the power charging rule, which includes: determining the total charging period and the total charging power of the total charging period; retrieve the first power charging rule and the second power charging rule supported by the charging pile module, the first power charging rule includes one of the time length charging rule and the ladder power charging rule, and the second power charging rule includes one of the unit power charging rule and the peak-valley power price charging rule; exhibiting the first power charging rule and the second power charging rule to the user, and receiving the current charging rule selected by the user from the first power charging rule and the second power charging rule; when the current charging rule selected by the user is the first power charging rule, and the charging pile module supports the time length charging rule, the charging amount is calculated based on the time length charging rule; when the current charging rule selected by the user is the first power charging rule, and the charging pile module supports the ladder power charging rule, the charging power of the total charging period is obtained, and the charging amount is calculated based on the charging power, the charging period and the ladder power charging rule; when the current charging rule selected by the user is the second power charging rule, and the charging pile module supports the unit power charging rule, the charging amount is calculated based on the total charging power and the unit power charging rule; when the current charging rule selected by the user is the second power charging rule, and the charging pile module supports the peak-valley power price charging rule, the current power price is determined by matching the total charging period and the peak-valley power price charging rule, and the charging amount is calculated based on the current power price and the total charging power.

[0055] In the embodiment, the total charging period is the actual charging period in the entire charging process, and the total charging power is the actual consumed power in the entire charging process. In order to meet the needs of different users, the charging pile in the embodiment is compatible with the first power charging rule and the second power charging rule.

[0056] The first electricity charging rule focuses on the time or power dimension of the charging process. The time length charging rule and the power charging rule are incompatible in the same charging system. Therefore, the charging pile module usually adopts one of them. The time length charging is suitable for low-power slow charging scenarios. The step power charging sets different rates for different power segments (such as low power and high power) to encourage users to reasonably use charging resources.

[0057] The second electricity charging rule focuses on the actual consumption of electricity. The unit electricity charging is a fixed unit price mode. The peak-valley electricity price sets different electricity prices according to different time periods (peak, flat, and valley) to guide users to charge off-peak and optimize the load of the power grid. The unit electricity charging rule and the peak-valley electricity price charging rule are incompatible in the same charging system. Therefore, the charging pile module usually adopts one of them.

[0058] When the user's vehicle is connected to the charging device, the interactive interface of the card reader module displays the two electricity charging rules supported by the current charging device. The user selects one from the first electricity charging rule and the second electricity charging rule. The charging device charges based on the current charging rule selected by the user.

[0059] For the first electricity charging rule, the time length charging rule is a unit time rate, such as 0.5 yuan / minute. The charging amount = total charging time (total charging period) x unit time rate. The step power charging rule divides the charging power into multiple intervals, such as 0-30kW for the first step, 30-60kW for the second step, and >60kW for the third step. Each interval corresponds to a different time rate, such as A yuan / minute for the first step and B yuan / minute for the second step, where B>A. The metering module collects the charging power in real time and records the duration corresponding to each power interval, such as 20 minutes in the 30-60kW interval and 15 minutes in the 0-30kW interval. The product of the duration of each interval and the corresponding step rate is calculated, and the sum of the charges of each interval is taken as the charging amount.

[0060] For the second electricity charging rule, the unit electricity charging rule is a fixed unit price, such as 1.5 yuan / kWh, and the fee is calculated according to the total charging electricity. The peak-valley electricity price rule divides a day into peak, flat, and valley periods, such as the peak period is 8:00-22:00, and the electricity price is 1.8 yuan / kWh; the valley period is 22:00-8:00 the next day, and the electricity price is 1.2 yuan / kWh. Different time periods correspond to different electricity prices. The total charging period is split into each electricity price interval. If the total charging period 14:30:25-15:10:10 is completely in the peak period (8:00-22:00), no splitting is needed. If the total charging period crosses the time period (such as 21:50-22:10), the time length is split according to the time period boundary, such as 21:50-22:00 is the peak period, and 22:00-22:10 is the valley period. The charging electricity of each charging period is determined, and the product of the charging electricity and the current electricity price of the corresponding period is calculated as the charging amount of the charging period. The sum of the charging amounts of the charging periods is calculated as the charging amount.

[0061] The embodiment can adapt to the charging pile performance in different scenarios and the personalized charging billing needs of users by providing multi-dimensional billing rules. Meanwhile, the clear rule calling and calculation logic ensures the compliance and transparency of the billing process, and reduces the billing disputes between users and operators.

[0062] In a possible implementation of the embodiment of the application, the method further includes: When it is monitored that the remaining electricity information of the current vehicle meets the charging demand, the control module disconnects the output of the charging pile module; The idle duration is timed from the disconnection of the output of the charging pile module, and when the idle duration reaches an idle duration threshold, an idle billing duration between the idle duration threshold and the time when it is monitored that the charging interface of the current vehicle is disconnected from the charging pile module is determined. The idle fee is calculated based on the idle billing duration and an idle billing rule, and the idle fee is added to the charging amount.

[0063] In the embodiment, when the vehicle battery electricity reaches the charging demand set by the user (such as the electricity when the battery is fully charged or the target electricity for mileage supplement), the output is disconnected in time, which can avoid damage to the battery caused by overcharging and release the charging pile resource as early as possible to improve the equipment turnover rate. If the user does not pull out the charging pile in time after completing the charging, the charging pile resource will be occupied, which prevents other users from using the charging pile. By setting an idle duration threshold (such as 5 minutes), the user is charged when the idle duration threshold is exceeded, which can urge the user to leave in time through economic means and improve the utilization rate of the charging pile. The idle billing duration is the actual disconnection time of the charging interface minus the time when the idle duration threshold is reached. The idle billing rule includes a unit time idle rate, and the idle fee is the unit time idle rate multiplied by the idle billing duration.

[0064] The embodiment avoids the life attenuation caused by overcharging of the battery by timely disconnecting the charging output; and the idle billing mechanism can effectively urge the user to timely unplug the gun after charging is completed, reduce the idle of the charging pile resource, improve the equipment turnover rate, especially during the charging peak period, more users can quickly use the charging pile, and the service efficiency of the public charging facility is optimized.

[0065] In a possible implementation of the embodiment of the application, the control charging pile module charges the current vehicle, comprising: In the process of charging the current vehicle, the battery temperature of the current vehicle and the outlet temperature of the charging pile module are monitored in real time; The upper limit of the basic charging power is determined based on the remaining power information of the current vehicle; The upper limit of the charging power is obtained by adjusting the upper limit of the basic charging power based on the battery temperature and the outlet temperature, and the charging pile module is controlled to charge the current vehicle under the constraint of the upper limit of the charging power.

[0066] In the embodiment, temperature is the safety red line of charging power. When the battery temperature is too high, high-power charging may cause thermal runaway. When the outlet temperature of the charging pile is too high, the insulation layer of the line may melt and cause short circuit. The basic charging power needs to be dynamically adjusted according to the real-time changes of the two types of temperature to ensure that the charging process is always in the safe temperature range.

[0067] The correspondence between the remaining power interval and the basic charging power is pre-divided. When the remaining power is small, a larger charging power can be used, and when the remaining power is large, a smaller charging power is used to protect the vehicle battery. The corresponding relationship can be pre-set according to actual experience and stored in the control module. The control module selects the corresponding basic charging power according to the interval in which the real-time remaining power is located.

[0068] The battery temperature threshold and the outlet temperature threshold are pre-set. If the battery temperature does not exceed the battery temperature threshold, and the outlet temperature does not exceed the outlet temperature threshold, the basic charging power is not adjusted, and the current vehicle is directly charged according to the basic charging power. When one of the battery temperature and the outlet temperature exceeds the corresponding threshold, the product of the basic charging power and the first proportion is taken as the adjusted charging power. When the battery temperature and the outlet temperature both exceed the corresponding pre-set, the product of the basic charging power and the second proportion is taken as the adjusted charging power. The first proportion and the second proportion are both less than 1, and the second proportion is less than the first proportion. The specific values of the first proportion and the second proportion can be set according to actual experience, and the embodiment is not limited.

[0069] The embodiment constructs a closed-loop control of safety monitoring-power adaptation through real-time temperature monitoring and dynamic power adjustment, which can not only avoid safety risks such as battery thermal runaway and device short circuit caused by excessively high temperature, but also match reasonable charging power constraints according to the remaining power, so as to balance the charging efficiency and the service life of the battery and the device under the premise of ensuring charging safety.
