[0024] In the embodiment of the present invention, high-price low connection refers to the behavior of users violating the power supply and use contract and related regulations, and arbitrarily connecting power equipment or power demand that should be subject to high power price standards to power lines that implement low power price standards in order to obtain improper electricity fee discounts. The behavior of high-price low connection not only disrupts the normal order of the power market, but also may cause damage to power facilities and affect the safety and stability of power supply.

[0025] Figure 1 This is a flow chart of a method for judging whether a household charging pile is high-priced and low-connected, provided by an embodiment of the present invention. This embodiment can be applied to monitoring whether household charging piles (for example, user residences and single-family villas in towns where charging piles are relatively sparse) have high-priced and low-connected conditions. This method can be executed by a judgment system for judging whether a household charging pile is high-priced and low-connected, and the judgment system can be implemented in the form of hardware and / or software. Figure 1 As shown, the method includes:

[0026] S110. Obtaining original data on electricity consumption of charging piles and original data on electricity meters for residents; wherein, the electricity price of charging piles includes valley price and non-valley price, and the valley price of charging piles is lower than the electricity price measured by household electricity meters; the electricity meters for residents are total meters.

[0027] The raw data of charging pile electricity consumption refers to the unprocessed data of the household charging pile recorded during the charging process, which includes, for example, basic power parameters such as the amount of electricity consumed by the charging pile, charging current, charging time and charging voltage. The household electricity meter refers to the electricity meter that records the electricity consumption of the user's household electrical equipment, which is usually installed at the power entrance of the house to facilitate access to the main power supply and reading.

[0028] The raw data of residential electricity meters refers to the unprocessed data that records the power consumption, charging current, charging time, charging voltage, etc. of all the user's electrical equipment within a certain period of time. Among them, the residential electricity meter is a total meter, that is, the data recorded by the residential electricity meter includes the data recorded by the charging pile and the data recorded by the household electricity meter.

[0029] Valley price refers to the lower electricity price provided by the power supply department for charging piles during the period of low electricity demand (such as night), encouraging users to charge during this period to balance the power load. Non-valley price refers to the higher electricity price provided by the power supply department for charging piles during the period of high electricity demand (such as daytime).

[0030] Specifically, the valley price of charging piles is lower than the electricity price of household appliances measured by household electricity meters, making it more economical for users to charge electric vehicles at night. However, in order to save electricity bills, some users connect electrical appliances that should be connected to household electricity meters to charging piles, which not only increases the cost of power generation, but also poses safety risks.

[0031] S120: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0032] Among them, data processing refers to the process of converting raw data into useful information through steps such as analysis, cleaning and conversion. Optionally, the data processing method includes: filtering processing and data calibration. Among them, filtering processing refers to the process of processing the raw data of charging pile electricity consumption and the raw data of residential electricity meters by applying specific algorithms or filters. Filtering processing can reduce or eliminate unnecessary components such as clutter, harmonics, pulsation, etc. in the data, so as to obtain smoother, more stable and high-precision electricity or current data. Data calibration refers to the process of adjusting and correcting the raw data of charging pile electricity consumption and the raw data of residential electricity meters to ensure their accuracy and consistency. Exemplarily, an embodiment of the present invention can adopt a multi-point calibration method, that is, by measuring at multiple calibration points with known accurate values, obtaining corresponding measurement values, and using these data to fit a calibration curve or model. The curve or model can effectively describe the response characteristics of the measuring device over the entire range, thereby achieving comprehensive calibration.

[0033] Charging pile electricity consumption data refers to the power parameters of the original data of charging pile electricity consumption after data processing, which may include parameters such as total charging power, charging time, average power and charging cost. Residential electricity meter data refers to the power parameters of the original data of residential electricity meter after data processing, which may include parameters such as total charging power, charging time, average power and charging cost.

[0034] Specifically, the charging pile electricity consumption data and the residential electricity meter data provide a basis for the subsequent analysis of the charging pile usage and household electricity consumption.

[0035] S130. Determine whether there is a high-price, low-connection situation based on the charging pile electricity consumption data and / or the residential electricity meter data; if there is a high-price, low-connection situation, generate an alarm signal.

[0036] The warning signal refers to a notification or alarm signal generated by the household charging pile high-price low-connection judgment system according to the warning signal when the charging pile is detected to have high-price low-connection electricity consumption. Exemplarily, the signal can be in the form of flashing lights, sound prompts or information display.

[0037] S140. Activate an early warning mechanism according to the alarm signal.

[0038] Among them, the early warning mechanism refers to a series of response measures and procedures that are automatically initiated in the monitoring system according to the alarm signal, which is used to timely identify, evaluate and respond to potential risks or problems to reduce losses and ensure system safety.

[0039] Optionally, the early warning mechanism includes: at least one of: sound and light alarm, SMS notification, application message push and uploading to a cloud server.

[0040] Among them, sound and light alarm refers to an alarm method that uses a combination of sound and light to prompt. SMS notification refers to a method of sending alarm signals via SMS. Application message push refers to a method of sending alarm notifications via mobile applications. Upload to cloud server refers to a method of storing data or alarm information in a cloud server to send alarm signals.

[0041] Specifically, the above four methods (sound and light alarm, SMS notification, application message push and uploading to cloud server) can be used in combination or separately. Through a reasonable early warning mechanism, the alarm prompts for high-price low-acceptance behavior can reduce economic losses and safety risks.

[0042] The technical solution of the embodiment of the present invention determines whether the charging pile has a high price and low connection by monitoring the electricity consumption data of the household charging pile and the electricity meter of the residents, and generates an alarm signal after the high price and low connection is found, thereby starting the early warning mechanism. This solution has the advantages of real-time monitoring and automatic response, can timely identify and handle the high price and low connection situation, significantly improve the economy and safety of power supply, and overcome the disadvantage that there is no relevant method for detecting the high price and low connection situation of the charging pile in the prior art.

[0043] Based on the above-mentioned embodiments of the invention, optionally, the charging pile power consumption data includes charging pile historical data and charging pile real-time data.

[0044] Among them, charging pile historical data refers to the charging pile power usage information recorded by the home charging pile within a certain time range before the current charging stage, including past charging records, power consumption, charging time, charging costs, etc. Charging pile real-time data refers to the charging pile power usage information measured and recorded at the current moment, including current current, voltage, instantaneous power and charging status, etc.

[0045] Optionally, the charging pile power consumption data includes at least one of the charging pile rated current and the charging pile rated power.

[0046] The rated current of a charging pile refers to the maximum current value specified when the charging pile is designed and manufactured, usually in amperes, representing the current that the charging pile can safely transmit under normal working conditions. The rated power of a charging pile refers to the maximum power value specified when the charging pile is designed and manufactured, usually in kilowatts, representing the maximum power output that the charging pile can provide under normal working conditions.

[0047] Specifically, the rated current and rated power of the charging pile are important indicators for judging the operating status of the charging pile, and are crucial to ensuring the safe use and efficient charging of the charging pile.

[0048] On the basis of the above-mentioned embodiments, this embodiment further refines the step of "determining whether there is a high-price, low-connection situation based on the charging pile electricity consumption data and / or the residential electricity meter data" in S130. Figure 2 A flowchart of another method for determining whether a household charging pile is high-priced and low-connected provided by an embodiment of the present invention.

[0049] Optional, such as Figure 2 As shown, the method includes:

[0050] S210. Obtain the original data of electricity consumption of charging piles and the original data of electricity meters for residents; wherein, the electricity price of charging piles includes valley price and non-valley price, and the valley price of charging piles is lower than the electricity price measured by household electricity meters; the electricity meters for residents are the total meters.

[0051] S220: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0052] S231. Obtain the stable fluctuation range of the charging pile in each time period according to the historical data of the charging pile.

[0053] Among them, the stable fluctuation range refers to the normal fluctuation range of parameters such as power and current within a specific time period determined when analyzing the historical data of charging piles. It is usually obtained through statistical analysis methods and reflects the power consumption characteristics of household charging piles under normal operating conditions.

[0054] Specifically, electricity consumption in different time periods may be affected by many factors (such as season, weather, user habits, etc.). The historical data of charging piles reflects the electricity consumption patterns of charging piles in different time periods. By analyzing these data, the fluctuation range under normal circumstances can be identified.

[0055] S232. If the real-time data of the charging pile exceeds the stable fluctuation range during the corresponding period, there is a high price and low connection.

[0056] Specifically, if the real-time data exceeds the stable fluctuation range, it means that the current electricity consumption is significantly different from the historical normal state. This may be because the user mistakenly connects the high-priced electrical appliances to the low-priced equipment (i.e. high price and low connection).

[0057] S233. If there is a high price and low connection situation, an alarm signal is generated.

[0058] S240. Activate an early warning mechanism according to the alarm signal.

[0059] The technical solution provided by the embodiment of the present invention determines whether the charging pile has a high price and low connection by monitoring whether the real-time charging data of the charging pile is within a stable fluctuation range. Under normal circumstances, the real-time charging data of the charging pile will remain in a relatively stable range. If abnormal fluctuations are detected in the charging data (for example, the charging current and / or charging power are not within the stable fluctuation range), there may be a high price and low connection, and corresponding measures need to be taken. This technical solution can effectively prevent equipment damage or safety hazards caused by high price and low connection, and ensure the safety of the charging process.

[0060] Based on the above-mentioned embodiments of the invention, optionally, the charging pile power consumption data includes the charging pile historical current data and the charging pile real-time current data.

[0061] Among them, the charging pile historical current data refers to the charging pile current information recorded in the past period of time, including the charging current values ​​and related charging record information in different time periods. These data are used to analyze the usage patterns, performance trends and current changes of the charging piles. The charging pile real-time current data refers to the current information of the charging pile measured and recorded at the current moment, reflecting the real-time operating status of the charging pile.

[0062] Figure 3 A flowchart of another method for determining whether a household charging pile is high-priced and low-connected provided by an embodiment of the present invention. Based on the above embodiments, this embodiment refines the "determining whether there is a high-priced and low-connected situation based on the charging pile electricity consumption data and / or the residential electricity meter data" in S130. Optionally, Figure 3 As shown, the method includes:

[0063] S310. Obtain the original data of electricity consumption of charging piles and the original data of electricity meters for residents; wherein, the electricity price of charging piles includes valley price and non-valley price, and the valley price of charging piles is lower than the electricity price measured by household electricity meters; the electricity meters for residents are the total meters.

[0064] S320: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0065] S331. Obtain the peak current of the charging pile according to the historical current data of the charging pile.

[0066] Among them, the current peak refers to the highest value of the current transmitted by the charging pile in a specific time period, determined by analyzing the historical current data of the charging pile, which reflects the maximum load capacity of the charging pile under normal use.

[0067] S332. If the real-time current data of the charging pile exceeds the current peak value, there is a high price and low connection.

[0068] Specifically, the current peak has taken into account the maximum load capacity and safety standards of the equipment. Under normal circumstances, the current of the charging pile should be kept below the current peak. If the real-time current data exceeds the current peak, it means that the charging pile is bearing a current that exceeds its design and safety limits. This phenomenon may be related to the start-up or operation of loads that are not used for charging, that is, there is a high price and low connection.

[0069] S333. If there is a high price and low connection situation, an alarm signal is generated.

[0070] S340. Activate an early warning mechanism according to the alarm signal.

[0071] The technical solution provided by the embodiment of the present invention determines whether the charging pile has high-price low connection by monitoring whether the real-time current data exceeds the current peak value, and then takes corresponding measures. This technical solution can effectively prevent equipment damage or safety hazards caused by high-price low connection, and ensure the safety of the charging process.

[0072] Based on the above-mentioned embodiments of the invention, optionally, the charging pile power usage data includes rated power data, charging time data and charging power data.

[0073] The rated power data refers to the maximum power value that the charging pile can provide under normal working conditions. The charging time data refers to the actual charging duration during the charging process. The charging power data refers to the actual amount of electrical energy charged into the battery during the charging process.

[0076] S420: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0077] S431. Obtain charging power calculation data according to the rated power data and the charging duration data.

[0078] The charging power calculation data refers to the theoretical value of the charging power calculated based on the rated power data and the charging time data. The charging power calculation data can be calculated using the following formula:

[0079] Charging power calculation data = rated power data × charging time data

[0080] Specifically, the charging power calculation data is based on the charging efficiency under ideal conditions, and aims to determine the amount of power that the charging pile should provide within a specific time.

[0081] S432: If the difference between the charging power data and the charging power calculation data exceeds the set threshold, there is a high price and low connection.

[0082] The set threshold refers to the difference range between the pre-set charging power data and the charging power calculation data.

[0083] Specifically, if the difference between the actual charging power data and the calculated charging power data exceeds a set threshold, this indicates that the charging pile may have a high price and low connection.

[0084] S433. If there is a high price and low connection situation, an alarm signal is generated.

[0085] S440. Activate an early warning mechanism according to the alarm signal.

[0086] The technical solution provided by the embodiment of the present invention determines whether there is a high-price low connection at home charging pile by monitoring the difference between the charging power data and the charging power calculation data, and judges whether it exceeds the set threshold, and takes corresponding measures in time. This technical solution can effectively prevent equipment damage or safety hazards caused by high-price low connection, and ensure the safety of the charging process.

[0087] Based on the above embodiments, optionally, the charging pile electricity consumption data includes first incremental data of charging electricity within a set time interval, and the residential electricity meter data includes second incremental data of total household electricity within a set time interval.

[0088] The first incremental data refers to the change in the amount of electricity charged by the charging pile within a set time interval, reflecting the actual amount of electricity charged by the charging pile during this time period. The second incremental data refers to the change in electricity monitored by the residential electricity meter within a set time interval, that is, the change in the total meter, including the incremental amount of electricity charged by the charging pile and the incremental amount of electricity charged by the household electricity meter.

[0089] Figure 5 A flowchart of another method for determining whether a household charging pile is high-priced and low-connected provided by an embodiment of the present invention. Based on the above embodiments, this embodiment refines the "determining whether there is a high-priced and low-connected situation based on the charging pile electricity consumption data and / or the residential electricity meter data" in S130. Optionally, Figure 5 As shown, the method includes:

[0090] S510.

[0091] S520: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0092] S531. If the first incremental data does not match the second incremental data, there is a high price and low connection.

[0093] Specifically, the first incremental data reflects the incremental power consumption in the charging pile; the second incremental data reflects the incremental power consumption of the total meter, including the incremental power consumption of the charging pile and the incremental power consumption of the household meter. In actual use, the data of the household meter is stable. If the first incremental data does not match the second incremental data, it means that the high-priced electrical equipment measured by the household meter may be connected to the charging pile, that is, high price and low connection.

[0094] S532. If a high price and low connection situation exists, an alarm signal is generated.

[0095] S540. Activate an early warning mechanism according to the alarm signal.

[0096] The technical solution provided by the embodiment of the present invention determines whether the charging pile has high-price low connection by comparing the increment in the charging pile with the increment of electricity measured by the residential electricity meter, and takes corresponding measures in time. This technical solution can effectively prevent equipment damage or safety hazards caused by high-price low connection, and ensure the safety of the charging process.

[0097] On the basis of the above embodiments, optionally, the charging pile electricity consumption data includes charging power data, and the residential electricity meter data includes total household electricity consumption data.

[0098] Among them, the charging power data refers to the power actually charged into the electric vehicle battery by the charging pile during the charging process, reflecting the power provided by the charging pile within a specific time. The household total power data refers to the total power consumption of the household within a certain period of time, including the power of the household meter and the power of the charging pile.

[0101] S620: Process the original data of electricity consumption of charging piles and the original data of electricity meters for residents respectively to obtain the electricity consumption data of charging piles and the electricity meter data for residents.

[0102] S631. Compare the charging power data with the total household power data; if the difference between the charging power data and the total household power data exceeds the set range, there is a high price and low connection.

[0103] The setting range refers to the range of the difference between the pre-set charging power data and the total household power data.

[0104] Specifically, in actual use, the data of the household electricity meter is relatively stable. If the difference between the charging power data and the total household power data exceeds the set range, it means that the power consumed by the household electricity meter is not recorded correctly, that is, the user may have connected the high-priced electrical equipment measured by the household electricity meter to the charging pile, resulting in a high-price and low-connection.

[0105] S632. If a high price and low connection situation exists, an alarm signal is generated.
