Description

Technical Field

[0001] The present application relates to the field of charging control technology, and in particular to a charging pile control method, device, storage medium and computer equipment. Background Art

[0002] Currently, the deployment of charging stations in some older communities, dormitory areas, and rural areas faces numerous challenges due to historical grid structural limitations and lagging infrastructure upgrades. Specifically, these areas often fail to undergo necessary grid upgrades during the initial installation of charging stations. Furthermore, the scattered and distant locations of substations limit power transmission efficiency. Furthermore, these charging stations are often designed and deployed without integration with IoT technologies and lack facilities for real-time user power collection and monitoring. Consequently, charging stations deployed in these areas generally lack automatic power regulation capabilities.

[0003] During peak electricity demand periods, charging stations, lacking the ability to automatically regulate power, can consume excessive amounts of power during charging, leading to a sharp increase in local grid load and, in turn, voltage drops. This not only severely restricts the charging efficiency of new energy devices like electric vehicles, causing frequent charging interruptions or failures, but can also cause household appliances to malfunction. Furthermore, the high power load of charging stations can cause line overloads, increasing the risk of fire and posing a potential safety hazard. Summary of the Invention

[0036] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0037] In some older communities, dormitories, and rural areas, historical factors hindered grid upgrades or remote substation locations. Furthermore, charging stations are often installed without IoT integration or user power collection systems, resulting in a lack of automatic power allocation capabilities. During peak power demand periods, charging stations may output high power without restriction, causing local voltage drops. This not only impacts charging efficiency but can also cause charging interruptions or render household appliances inoperable due to unstable voltage. More seriously, excessive loads can cause wiring overheating, increasing the risk of fires and other safety incidents.

[0038] In order to solve the above problems, the existing technology proposes a technical solution of installing power collection equipment to monitor and control the power output of the charging pile. Figure 1 As shown, the above technical solution collects the total household power and dynamically adjusts the charging pile power according to the preset maximum household power limit to prevent overload. However, this technical solution requires a preset maximum power for each charging pile, which increases the complexity of charging pile deployment and configuration. Secondly, the installation of dedicated power collection equipment also adds additional hardware costs. Thirdly, the charging pile must be able to communicate with the power collection equipment, further increasing the overall cost of charging pile installation.

[0039] In view of the shortcomings of the existing technology, this application provides a charging pile control method. This method utilizes the charging pile's built-in input voltage detection function to enable the charging pile to autonomously monitor the power grid status and dynamically adjust its output power accordingly. This method not only effectively avoids voltage fluctuations caused by excessive charging power, ensuring the normal use of household appliances, but also reduces safety hazards caused by overloads.

[0040] Based on the above ideas, in one embodiment, Figure 2 As shown, a charging pile control method is provided. This method is described using an internal control device of a charging pile as an example. The method comprises the following steps: when the charging pile is in a charging state, the charging voltage of the charging pile is monitored in real time, and the charging current of the charging pile is dynamically adjusted based on the charging voltage of the charging pile. The charging current is adjusted within a range between a base current and a rated current, or the charging current is adjusted to zero to control the charging pile to suspend charging. Through cyclic detection, the present invention maximizes charging using the maximum current that the power grid can withstand, thereby improving charging efficiency.

[0041] In this embodiment, the above-mentioned charging pile control method can be implemented by a control device inside the charging pile, the charging voltage of the charging pile can be collected by a voltage detection device provided inside the charging pile, and the charging current of the charging pile can be collected by a current detection device provided inside the charging pile. The control device can dynamically adjust the charging current based on the collected charging current based on the detection result of the charging voltage. Among them, the principle of adjusting the charging current after collecting the charging current is: during the charging process, the charging pile needs to provide a certain current capacity to the load (such as an electric vehicle), and the load will decide how much current to charge based on its own conditions. At different times, under different states of the load, under different current capacities provided by the charging pile, the load's decision may be different, and the decision of different loads is also different. The current flows from the charging pile to the load, and the current measured on the charging pile is consistent with the current on the load. Therefore, by sampling the charging current of the charging pile, the actual charging current of the charging pile can be measured, and then the charging current can be dynamically adjusted between the base current and the rated current based on the actual collected charging current, thereby ensuring the power safety of the charging pile and the smooth implementation of the charging process.

[0042] Specifically, in the charging state, the charging current I of the charging pile can be adjusted in real time by monitoring the charging voltage U of the charging pile, wherein the adjustment range of the charging current is between the basic current Imin and the rated current Imax, or it can be directly adjusted to 0, that is, the charging pile is controlled to suspend charging. In this embodiment, the basic current is the minimum charging current defined in the charging standard, for example, 6A, and the rated current is the rated current defined by the charging pile. It should be noted that the basic current Imin and the rated current Imax are pre-set by the control device inside the charging pile. The regulations of different countries or regions are different and are not specifically limited here.

[0043] Furthermore, during the charging process, when it is detected that the charging voltage of the power grid fluctuates greatly, the charging current can be actively adjusted so that the charging voltage and charging power of the power grid can be kept in a relatively balanced state. This balanced state runs through the entire charging process of the charging pile, so that the charging pile can guarantee the user's basic living electricity consumption while ensuring charging efficiency, and ensure electricity safety. When it is detected through the charging voltage that the quality of the power grid is no longer suitable for continued charging, such as when it is detected that the charging voltage has dropped to a certain range, the charging pile can be controlled to suspend charging to prevent the voltage from suddenly dropping and causing hidden dangers to electricity use. In some old communities, dormitory areas, rural areas and other electricity use scenarios, the large fluctuations in voltage with current are often caused by the aging of the transmission line or the insufficient rated power of the transmission line. By dynamically adjusting the charging power of the charging pile by the above method, the user's electricity safety can be ensured.

[0044] The technical solution provided by the above embodiment monitors the charging voltage of the charging pile in real time when the charging pile is in the charging state, and dynamically adjusts the charging current of the charging pile between the basic current and the rated current based on the charging voltage of the charging pile, or adjusts the charging current to zero to control the charging pile to suspend charging. The above method can realize automatic adjustment of the charging power without external power acquisition equipment, thereby ensuring the user's basic living electricity and electricity safety, avoiding the problem of charging failure caused by voltage drop, and realizing efficient charging even when the power grid quality is poor. The above method does not require any external power acquisition devices or equipment, effectively improves the safety and reliability of the system, and at the same time reduces the overall cost and installation complexity of the charging pile.

[0045] In one embodiment, Figure 3 As shown, the method for dynamically adjusting the charging current of the charging pile can be implemented in the following manner: when it is detected that the charging voltage is greater than or equal to a preset safety voltage threshold, the charging current is controlled to be dynamically adjusted between the basic current and the rated current; when it is detected that the charging voltage is less than the safety voltage threshold, the charging current is controlled to zero so that the charging pile suspends charging.

[0046] Specifically, the safety voltage threshold can be set according to the actual situation of the charging pile. For example, the safety voltage threshold can be set to 82% of the rated voltage of the charging pile. In this embodiment, when it is detected that the charging voltage is less than the safety voltage threshold, it indicates that the voltage quality of the power grid is no longer suitable for charging, and continuing to charge may cause dangerous conditions such as voltage drops. Therefore, when it is detected that the charging voltage is lower than the safety voltage threshold, the charging pile can be controlled to suspend charging to ensure the safety of electricity use. Accordingly, when the charging voltage is greater than or equal to the preset safety voltage threshold, the current value of the charging current can still be adjusted in real time according to the monitoring of the charging voltage to dynamically adjust between the basic current and the rated current, so that the charging voltage and charging power of the power grid can be maintained in a relatively balanced state, thereby ensuring the safety of electricity use.

[0047] In one embodiment, Figure 4 As shown, the method for controlling the dynamic adjustment of the charging current between the basic current and the rated current can be implemented in the following manner: cyclically executing the following method: when it is detected that the charging voltage is greater than the preset current-increasing voltage threshold for a period exceeding a first preset period, detecting whether the charging current is less than the rated current, wherein the current-increasing voltage threshold is greater than the safety voltage threshold; if the charging current is less than the rated current, increasing the charging current until the charging current reaches the rated current.

[0048] Specifically, the current-increasing voltage threshold can be set according to the actual situation of the charging pile. For example, the current-increasing voltage threshold can be set to 87% of the rated voltage of the charging pile. When it is detected that the charging voltage is greater than the current-increasing voltage threshold, it indicates that the quality of the power grid can withstand the charging behavior of the charging pile at this time, and the charging current can be appropriately increased to improve the charging efficiency. Based on this, the setting value of the current-increasing voltage threshold should be greater than the safety voltage threshold used to control the charging pile to suspend charging. In this embodiment, the current value of the charging current can be cyclically adjusted based on the detection value of the charging voltage. For example, each time it is detected that the duration of time when the charging voltage is greater than the current-increasing voltage threshold exceeds a first preset duration, and the charging current is less than the rated current, the charging current can be increased according to a preset step size, for example, the charging current is increased by 1A each time until the charging current increases to the rated current. It is understandable that the increase in charging current can also be determined based on the detected value of the charging voltage, or based on the relationship between the detected value of the charging voltage and the threshold, or determined in other ways. The length of the first preset time can be set according to actual conditions, for example, set to 3 minutes. The setting of the preset time is used to prevent frequent adjustments from causing charging failures. The preset time can also be set according to the voltage threshold to adjust the frequency. This embodiment is not specifically limited here. The above method can improve the charging efficiency of the charging pile while ensuring user safety.

[0049] In the above embodiment, before adjusting the charging current, it is necessary to first sample the charging current of the charging pile using a current detection device, and then increase the charging current output to the load based on the sampled charging current value. The purpose of current sampling is to determine whether the charging current I is less than the rated current Imax based on the current value actually measured on the charging pile. If the charging current I is less than the rated current Imax, the charging current is further increased, that is, the current capacity supplied to the load is increased. If the charging current I is greater than or equal to the rated current Imax, the charging current is set to the rated current to ensure the power safety of the charging pile.

[0050] In one embodiment, Figure 5 As shown, the method for controlling the dynamic adjustment of the charging current between the basic current and the rated current can also be implemented in the following way: cyclically executing the following method: when it is detected that the charging voltage is greater than or equal to the safety voltage threshold and is less than or equal to the preset current-increasing voltage threshold for a period exceeding a second preset period, detecting whether the charging current is greater than or equal to the basic current, wherein the current-increasing voltage threshold is greater than the safety voltage threshold; if the charging current is greater than or equal to the basic current, keeping the charging current unchanged or reducing the charging current so that the charging current is greater than or equal to the basic current.

[0051] Specifically, both the safety voltage threshold and the current-increasing voltage threshold can be set according to the actual situation of the charging pile. For example, the safety voltage threshold can be set to 82% of the rated voltage of the charging pile, and the current-increasing voltage threshold can be set to 87% of the rated voltage of the charging pile. In this embodiment, when it is detected that the charging voltage is greater than the safety voltage threshold, it indicates that the quality of the power grid can withstand the charging behavior of the charging pile at this time, but it is not appropriate to increase the charging current to avoid affecting the safety of electricity use. At this time, the current value of the charging current can be cyclically adjusted based on the detection value of the charging voltage. For example, each time it is detected that the time period is greater than or equal to the safety voltage threshold and less than or equal to the current-increasing voltage threshold exceeds the second preset time period, and the charging current is greater than or equal to the basic current, the charging current can be kept unchanged, or the charging current can be gradually reduced according to a certain proportion or according to a preset step size, while ensuring that the charging current is greater than or equal to the basic current. It is understood that the reduction value of the charging current can also be determined based on the detection value of the charging voltage or other methods. The setting value of the second preset time length can be set according to the actual situation, for example, set to 3 minutes. The setting of the preset time length is used to prevent charging failures caused by frequent adjustments. The preset time length can also be set according to the voltage threshold to adjust the frequency. This embodiment is not specifically limited. The above method can ensure the charging efficiency of the charging pile while ensuring user safety.

[0052] In the above embodiment, before adjusting the charging current, it is also necessary to first sample the charging current of the charging pile using the current detection device, and then reduce or maintain the charging current based on the sampled charging current result. The purpose of current sampling is to determine whether the charging current I is greater than or equal to the base current Imin based on the current value actually measured on the charging pile. If the charging current I is greater than or equal to the base current Imin, the charging current is reduced or maintained unchanged. If the charging current I is less than the base current Imin, the charging current is set to the base current Imin to ensure that the charging process can be completed smoothly.

[0053] In one embodiment, Figure 6 As shown, the method of controlling the charging pile to suspend charging can be implemented in the following way: looping the following method: when it is detected that the charging voltage is less than the safety voltage threshold for more than a third preset time, controlling the charging current to zero to suspend charging the charging pile.

[0054] Specifically, when the charging voltage is detected to be less than the safety voltage threshold for a period exceeding a third preset duration, it indicates that the grid voltage quality is already very poor, and this continuous deterioration is not a short-term transient state, but rather persists for a short period of time. At this point, continuing charging is likely to result in a dangerous condition such as a voltage sag. Therefore, when the charging voltage is detected to be less than the safety voltage threshold for a period exceeding the third preset duration, the charging pile can be controlled to suspend charging to ensure electricity safety. The set values ​​for the safety voltage threshold and the third preset duration can be set according to actual circumstances. For example, the safety voltage threshold can be set to 82% of the rated voltage of the charging pile, and the third preset duration can be set to 3 minutes. The preset duration is used to prevent frequent adjustments from causing charging failures. The preset duration can also be set based on the voltage threshold to adjust the frequency. This embodiment is not specifically limited here. Furthermore, after the charging pile is controlled to suspend charging, a warning message can be issued and displayed on a display device on the charging pile or through a user terminal or other device to remind the user to update or upgrade the transmission line, thereby ensuring electricity safety.

[0055] In one embodiment, Figure 7 As shown, after controlling the charging pile to suspend charging, the above-mentioned charging pile control method may further include the following steps: when the charging pile is in the suspended charging state, monitoring the charging voltage of the charging pile in real time; when it is detected that the charging voltage is greater than or equal to a preset restart voltage threshold, restarting charging, wherein the restart voltage threshold is greater than the safety voltage threshold; when it is detected that the charging voltage is less than the restart voltage threshold, controlling the charging current to zero to keep the charging pile in the suspended charging state.

[0056] Specifically, the restart voltage threshold can be set according to the actual situation of the charging pile. For example, the restart voltage threshold can be set to 87% of the rated voltage of the charging pile. When it is detected that the charging voltage is greater than or equal to the restart voltage threshold, it indicates that the power grid quality has slightly recovered compared to the power grid quality when charging was suspended, and can withstand the charging behavior of the charging pile, and charging can be resumed. Correspondingly, when it is detected that the charging voltage is less than the restart voltage threshold, it indicates that the power grid quality is still poor and not stable enough, and it is not suitable for resuming charging. Based on this, in order to ensure the safety of electricity use of the charging pile, the setting value of the restart voltage threshold should be greater than the safety voltage threshold used to control the charging pile to suspend charging. In this embodiment, when charging is suspended, the charging voltage of the charging pile can be monitored in real time, and when it is detected that the charging voltage is greater than or equal to the preset restart voltage threshold, charging is restarted to ensure charging efficiency. Correspondingly, when it is detected that the charging voltage is less than the restart voltage threshold, the charging current is controlled to zero to keep the charging pile in the suspended charging state, thereby ensuring power safety.

[0057] In one embodiment, Figure 8 As shown, the method for restarting charging can be implemented in the following way: looping the following method: when it is detected that the charging voltage is greater than or equal to the restart voltage threshold for a period exceeding a fourth preset period, controlling the charging pile to restart and charge with the basic current.

[0058] In this embodiment, when charging is suspended, the charging voltage of the charging pile can be cyclically detected. When it is detected that the charging voltage is greater than or equal to the restart voltage threshold for a period of time exceeding the fourth preset time, it indicates that the quality of the power grid has recovered to a state where charging is possible and has been stable for a short period of time. At this time, the charging pile can be controlled to restart and charge with the basic current. Among them, controlling the charging pile to restart and charge with the basic current can ensure the safety of the charging pile's electricity use and reduce the load on the power grid. In this embodiment, the set value of the restart voltage threshold and the set value of the fourth preset time can be set according to actual conditions. For example, the restart voltage threshold can be set to 87% of the rated voltage of the charging pile, and the fourth preset time can be set to 3 minutes, etc. The setting of the preset time is used to prevent charging failures caused by frequent adjustments, and the preset time can also be set according to the voltage threshold to adjust the frequency. This embodiment is not specifically limited here.

[0059] In one embodiment, Figure 9 As shown, before the charging pile is in the charging state, the above-mentioned charging pile control method may further include the following steps: in response to a charging instruction, reading the charging voltage of the charging pile; based on the charging voltage of the charging pile, setting the starting current of the charging pile, and controlling the charging pile to start and charge with the starting current, wherein the setting range of the starting current is between the base current and the rated current.

[0060] Specifically, the charging pile can initiate charging in response to a charging instruction. The charging instruction can be sent by the user or automatically after detecting that the charging pile is connected to the load to be charged. This embodiment does not limit the method for sending the charging instruction. In this embodiment, the control device can read the charging voltage in the current state in response to the charging instruction, and set the starting current of the charging pile based on the charging voltage, and then control the charging pile to start and charge with the starting current. The set value of the starting current is related to the voltage value of the charging voltage in the startup state. When the charging voltage is high and relatively stable, the starting current is also high, thereby improving the charging efficiency of the charging pile. When the charging voltage is low and less stable, the starting current is also low, thereby ensuring the safety of the charging pile's electricity use. In this embodiment, the set value of the starting current and the mapping relationship between the starting current and the charging voltage can be set according to actual conditions. The setting range is between the base current and the rated current. The specific set value and mapping relationship are not specifically limited in this embodiment.

[0061] In one embodiment, Figure 10 As shown, the method of controlling the charging pile to start and charge with a starting current can be implemented in the following manner: when it is detected that the charging voltage is greater than or equal to a preset starting voltage threshold, the charging pile is controlled to start and charge with a rated current; when it is detected that the charging voltage is less than the starting voltage threshold, the charging pile is controlled to start and charge with a basic current.

[0062] Specifically, the starting voltage threshold can be set based on the actual conditions of the charging pile. For example, the starting voltage threshold can be set to 90% of the charging pile's rated voltage. When the charging voltage is detected to be greater than or equal to the starting voltage threshold, it indicates that the grid quality is good, and charging can be started with a higher starting current to improve charging efficiency. When the charging voltage is detected to be less than the starting voltage threshold, it indicates that the grid quality is poor, and charging can be started with a lower starting current to ensure power safety. Therefore, the starting voltage threshold should be set to a value greater than the safety voltage threshold used to control the charging pile to suspend charging. In this embodiment, to reduce the complexity of the startup process control, when the charging voltage is detected to be greater than or equal to a preset starting voltage threshold, the charging pile can be controlled to start and charge at the rated current. When the charging voltage is detected to be less than the starting voltage threshold, the charging pile can be controlled to start and charge at the base current. Furthermore, during the charging state, the charging voltage of the charging pile can be monitored in real time, and the charging current of the charging pile can be dynamically adjusted between the base current and the rated current based on the charging voltage. Alternatively, when the grid quality is detected to be poor and charging cannot continue, the charging current can be adjusted to zero to control the charging pile to suspend charging. In this embodiment, when it is detected that the charging voltage in the startup state is lower than the safety voltage threshold, it is still necessary to start charging with the basic current, and monitor the charging voltage in real time during the charging process. When it is detected that the charging voltage does not meet the charging conditions, the charging pile is controlled to suspend charging to ensure electricity safety.

[0063] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, a charging pile control method is provided, which includes:

[0064] Step 1: In response to the charging instruction, read the charging voltage of the charging pile.

[0065] Step 2: When it is detected that the charging voltage is greater than or equal to the preset starting voltage threshold, the charging pile is controlled to start and charge with the rated current; when it is detected that the charging voltage is less than the starting voltage threshold, the charging pile is controlled to start and charge with the basic current.

[0066] Loop through steps 3 to 6:
