First embodiment
Referring to fig. 2, fig. 2 is a flowchart illustrating a charging order settlement method according to a first embodiment of the present invention, where the method includes:
step S10: obtaining a first electric energy value measured by the independent measuring module when the charging pile starts to charge; wherein, independent metering module with fill electric pile and be connected.
In step S10, when the charging pile charges the vehicle, the charging pile may measure charging data generated by the charging vehicle during the charging process, and the measured content may include the charging capacity, the charging time, the charging current, the charging voltage, and the like. These charging data may be uploaded to the stub cloud platform. The pile cloud platform can generate a charging order according to the charging data.
Independent metering module is independent outside filling electric pile. The charging data for charging is separately metered, and the independent metering module and the operator platform can be directly connected in a communication mode in the embodiment. After the operator platform issues the charging start instruction to the charging pile, the charging pile can start charging the charging vehicle based on the charging start instruction. In this case, the individual metering module can meter a first electrical energy value. The first electric energy value can be the count of an electric energy meter in the charging pile or the count of an electric energy meter externally connected with the charging pile. The charging starting instruction and the charging ending instruction issued by the operator platform can pass through the pile cloud platform and then are sent to the charging pile through the pile cloud platform. For the charging pile directly communicating with the operator platform, the charging start instruction and the charging end instruction can be directly sent to the charging pile by the operator platform.
Step S20: and obtaining a second electric energy value measured by the independent measuring module when the charging pile finishes charging.
In step S20, after the operator platform issues a charging end command to the charging pile, the charging pile may end charging the charging vehicle based on the charging end command. At this time, the independent metering module can meter a second electric energy value. Similarly, the second electric energy value may be a count of an electric energy meter in the charging pile or a count of an electric energy meter externally connected to the charging pile.
In steps S10-S20, the acquisition of the first and second electrical energy values may be uploaded by the independent metering module. Specifically, in a first implementation manner, when the independent metering module obtains the first electric energy value or the second electric energy value through metering, the first electric energy value or the second electric energy value may be uploaded to the operator platform and stored on the operator platform. In a second implementation manner, when the independent metering module obtains the first electric energy value or the second electric energy value through metering, the first electric energy value or the second electric energy value is stored in a local internal memory of the independent metering module. And after the operator platform issues the charging ending instruction and the independent metering module finishes metering the second electric energy value, uploading the first electric energy value and the second electric energy value which are stored in the independent metering module locally to the operator platform. Or when the operation platform receives a charging order uploaded by the pile cloud platform or the charging pile, the operator platform sends a charging metering acquisition request to the independent metering module; and when the independent metering module receives the acquisition request, uploading the first electric energy value and the second electric energy value stored in the independent metering module to an operator platform. The metering of the independent metering module to charging pile and the metering of charging pile itself are mutually separated in this embodiment, and the channel of uploading data by the independent metering module and the channel of uploading charging orders by charging pile are two different channels, and the accuracy of the data uploaded by the independent metering module is guaranteed by the two channels mutually independently.
For the above two implementation manners, the control process of the independent metering module in steps S10-S20 has the following specific implementation manners:
first, the data metered by the independent metering module is not stored locally at the independent metering module.
Step S10 specifically includes: when the operator platform issues a charging starting instruction to the charging pile or the pile cloud platform, the operator platform sends a metering starting instruction to the independent metering module so that the independent metering module meters a first electric energy value of the charging pile according to the metering starting instruction; the operator platform then receives the first electrical energy value sent by the independent metering module.
Step S20 specifically includes: when the operator platform issues a charging ending instruction to the charging pile or the pile cloud platform, the operator platform sends a metering ending instruction to the independent metering module so that the independent metering module meters a second electric energy value of the charging pile according to the metering ending instruction; and then, receiving a second electric energy value sent by the independent metering module.
Further, in this implementation, a structural component of an independent metering module is also provided, including: the device comprises a first control unit, an ammeter interface, a first communication unit and a power supply interface. The first control unit is used for measuring the electric energy meter of the charging pile, and the measured electric energy value is the value of the electric energy meter in the charging pile read through the electric meter interface. The first control unit may be a single chip microcomputer. Such as a 51-chip microcomputer, STM32, etc. The ammeter interface is arranged on the single chip microcomputer and used for connecting the charging pile, and the ammeter in the charging pile is connected for information input. The signal of the electric meter interface should match with the interface on the electric energy meter, and an RS485 interface can be adopted in the embodiment. And the first communication unit is used for communicating with the operator platform and receiving and transmitting data interacted between the operator platform and the independent metering module. The first communication unit can be a mobile/wireless communication module, and the communication mode can be 4G communication, 5G communication, 6G communication, WIFI, Bluetooth and the like. The power interface can be connected to a power supply source in the charging pile and used for supplying power for the independent metering module.
At this time, step S10 includes: the operator platform sends a metering starting instruction to the first communication unit so that the first control unit meters the first electric energy value according to the metering starting instruction; the electric meter interface is connected with the charging pile and is used as an interface for metering the first electric energy value; the carrier platform receives the first electrical energy value transmitted by the first communication unit.
At this time, step S20 includes: the operator platform sends a metering ending instruction to the first communication unit so that the first control unit meters a second electric energy value according to the metering ending instruction; the electric meter interface is connected with the charging pile and is used as an interface for metering a second electric energy value; the carrier platform receives the second electrical energy value transmitted by the first communication unit.
Second, the data metered by the independent metering module may be stored locally at the independent metering module.
Step S10 specifically includes: the operator platform records first time information of issuing a charging start instruction to the charging pile; then, the operator platform acquires a first electric energy value corresponding to the first time information from the independent metering module; the first time information is the moment when the charging pile starts to charge.
Step S20 specifically includes: the operator platform records second time information of issuing a charging ending instruction to the charging pile; then, the operator platform acquires a second electric energy value corresponding to the second time information from the independent metering module; and the second time information is the moment when the charging pile finishes charging.
Further, in this implementation, a structural component of an independent metering module is also provided, including: a second control unit, a shunt and a second communication unit. Wherein, the second control unit is used for measuring the electric quantity of charging of filling electric pile, but external memory chip of singlechip. The second control unit can be a single chip microcomputer; such as a 51-chip microcomputer, STM32, etc. One end of the shunt is connected with an output loop of the charging pile, and the other end of the shunt is connected with the second control unit through a specific electric energy meter.
The specific implementation of the flow divider can be as follows: connect an accurate small resistance alone between filling electric pile and the rifle that charges, through carrying out voltage detection and calculating the current value to this resistance. The specific electric energy meter measures the electric energy of the charging gun through the current value.
And the specific electric energy meter is used for recording the electric energy value. The second control unit performs the measurement of the charged amount by reading the value of the specific electric energy meter. And the second communication unit is used for communicating with the operator platform and receiving and transmitting data interacted between the operator platform and the independent metering module. The second communication unit can be a mobile/wireless communication module, and the communication mode can be 4G communication, 5G communication, 6G communication, WIFI, Bluetooth and the like. In such an embodiment, a particular power source may be used to provide power; also can be connected and fill the inside power supply of electric pile and supply power.
At this time, step S10 includes: the operator platform sends a first electric energy value acquisition request to the second communication unit so that the second control unit inquires the first electric energy value; the first electric energy value obtaining request carries first time information, the first time information corresponds to a first electric energy value, and the first electric energy value is recorded after passing through the current divider. The carrier platform then receives the first electrical energy value transmitted by the second communication unit.
At this time, step S20 includes: the operator platform sends a second electric energy value acquisition request to the second communication unit so that the second control unit inquires the second electric energy value; and the second electric energy value acquisition request carries second time information, the second time information corresponds to a second electric energy value, and the second electric energy value is recorded after passing through the shunt. The carrier platform then receives the second electrical energy value transmitted by the second communication unit.
When the charging gun charges the charging vehicle, the second communication unit can measure the electric energy meter connected with the shunt in real time, and the measured electric energy value data and the measured time information are stored in a group to form measuring data. The data can be saved in the second control unit or saved in a memory chip connected with the second control unit. When the second communication unit receives the electric energy value acquisition request, the second control unit may search the stored measurement data for the electric energy value corresponding to the first/second time information based on the first/second time information carried in the electric energy value acquisition request. The first time information corresponds to a first electrical energy value and the second time information corresponds to a second electrical energy value. The independent metering module is recorded in real time, and meanwhile the first time information, the second time information, the charging starting instruction and the charging ending instruction are determined by the operator platform, so that the electric energy value acquired by the operator platform from the independent metering module can be more accurate. The problem that the charging pile starts to be charged and the metering is asynchronous when the independent metering module is used for generating the charging pile is avoided.
Further, the independent metering module can be further provided with a temperature acquisition unit and a communication interface connected with a BMS (Battery Management System); wherein, temperature acquisition unit and communication interface all are connected with the second control unit.
The temperature acquisition unit can distribute on filling a plurality of collection points in electric pile for the temperature of different positions on the electric pile is filled in the collection. The collected temperature can be uploaded to an operator platform or a charging pile platform, and then the change of the temperature and the current along with the time when the charging pile is charged can be established. When the temperature of a certain position exceeds a preset first temperature threshold value, the charging current can be subjected to feedback regulation so as to reduce the charging current and guarantee safety.
The communication interface may be a CAN (Controller Area Network, CAN) interface. CAN messages in the interaction process of the charging pile and the vehicle CAN be collected through the communication interface and then stored. After the independent metering module receives an acquisition instruction which is sent by the pile cloud platform/operator platform and used for acquiring the CAN message, the independent metering module uploads the CAN message through the second communication unit. After uploading, the message can be identified, whether the message is in compliance or not can be identified, and the like.
In addition, the battery temperature data of the charging vehicle can be collected through the communication interface and uploaded to an operator platform. A curve of battery temperature versus charge time can be constructed on the operator platform. And when the temperature of the battery exceeds a preset second temperature threshold, the charging current can be subjected to feedback regulation so as to reduce the charging current and ensure the safety of the charging vehicle.
Furthermore, through the electric energy data uploaded by the independent metering module, under the condition that different electricity prices in different periods can be built on the operator platform, a charging quantity change curve of the charging quantity of the charging pile along with the time is formed. Through the comparison of the charging quantity change curves of different periods and different electricity prices, whether the charging pile or the charging gun is aged or not can be identified. Or whether the charging post is considered to be changed at different times. For example, when the fluctuation of the curve change is large, the charging pile should be troubleshooting, for example, when the average charging amount in the charging amount curve is degraded to 5%, it may be considered that the charging pile may be out of order or aged. The decline of the charging amount indicates that in the charging process of the charging pile, when the charging time and the charging output parameters are the same, the output electric energy of the charging pile cannot reach the standard output electric energy of the charging pile. The fault or quantification of the charging pile is judged more accurately and reliably through the charging quantity change curve, large-scale identification and judgment can be carried out, and the judgment of the fault can be realized; in addition, comprehensive evaluation can be carried out through a plurality of charging quantity curves, and judgment errors are avoided.
Step S30: and obtaining the checking charge quantity of the charging pile according to the difference value of the second electric energy value and the first electric energy value.
In step S30, since the independent metering system directly meters the charging pile, the first and second electric energy values do not pass through the pile cloud platform upload value operator platform. The actual electric quantity that fills of reflection that the electric pile corresponds the charging vehicle that the check-up charge volume can be more accurate. And calculating the difference value between the second electric energy value and the first electric energy value on the operator platform, and using the difference value as a verification charging amount.
Step S40: receiving a charging order sent by the pile cloud platform after the charging of the charging pile is finished, and obtaining the charging amount of the order; and the order charging amount is the charging amount recorded on the charging order.
It should be noted that the execution sequence of step S30 and step S40 is not limited.
In step S40, the generation of the charging order may be generated locally in the charging pile or generated on the pile cloud platform. When the pile cloud platform is generated, the pile cloud platform can generate a charging order according to the electric energy value measured by the charging pile and/or the measured time information. The measured time information is the charging time and the starting and stopping time of the charging pile for charging the charging vehicle. Specifically, the content of the charge order may include a length of time of charging, a charge amount, a unit price of charging, a charge address, an order number, and the like.
Step S50: and judging whether the deviation between the order charging amount and the check charging amount is larger than a preset deviation threshold value or not.
In step S50, the deviation of the order charge amount from the verification charge amount is the difference therebetween. The deviation threshold may be preset. For example, when a deviation of the order charge amount results in an error of the amount of the order settlement within 1%, the deviation may be considered reasonable; and the maximum value of the amount error does not exceed 1 yuan. And finally, carrying out reverse calculation by using the maximum value of the amount error of order settlement as 1 yuan to obtain a setting mode of the deviation threshold. Specifically, the deviation threshold value may be set as a proportion of the deviation or a charge amount of the deviation; or both may be provided simultaneously. For example, the deviation threshold may be a deviation ratio within 1%, while the amount of charge of the deviation does not exceed 0.2 kw.h; the data of the set deviation threshold can be adjusted more as required.
Further, in or after step S50, the order charging time in the charging order may be compared with the actual charging time to determine whether the order charging time is accurate. The actual charging time is a difference between the second time information and the first time information.
Step S60: if yes, settlement is carried out based on the backup order; wherein the backup order is an order generated based on the first and second electrical energy values.
In step S60, if the deviation between the order charging amount and the check charging amount is greater than the preset deviation threshold, it indicates that the charging order uploaded by the pile cloud platform is an error order. And if not, determining that the charging order is correct, and performing settlement operation. Further, if the order charging time is compared with the actual charging time in or after step S50; then the charge order is determined to be the correct order when both the order charge time and the order charge amount are accurate in step S60. And if any one of the order charging time and the order charging amount is inaccurate, determining that the charging order is a wrong order.
After determining that the charging order is a correct order, the operator platform may calculate the charge of the charging order according to a preset charging model, and/or confirm the charge of the charging order.
Further, if the order is determined to be a wrong order; the charge settlement for charging the charging vehicle at this time can be realized as follows.
1. And the operator platform acquires the backup order from the independent metering module.
In the independent metering module, a cost model can be preset. The independent metering module acquires the charge based on the first and second measured electric energy values and the time difference between the first and second measured electric energy values. And finally forming a backup order. When the operator platform determines that an error order is made, the operator platform can issue an instruction for obtaining a backup order, and the backup order is sent to the operator platform by the independent metering module for settlement. The charging pile or the pile cloud platform can complete correct settlement of charging cost for the user under the condition that the charging order is wrong; in addition, in the mode, the calculation of the backup order is carried out in the independent metering module, so that the calculation load of the operator platform can be reduced.
2. And regenerating the backup order by the pile cloud platform.
