Description

[0002] Electric vehicles are vehicles that use an onboard power source as their motive power, use an electric motor to drive the wheels, and comply with all requirements of road traffic and safety regulations. Since their impact on the environment is relatively smaller than that of traditional vehicles, their prospects are widely optimistic. Therefore, the charging piles for charging vehicles need to be increasingly improved. We often see car charging piles in various service areas, parking lots and other public places. The car charging pile equipment on the market is usually placed directly in the open air and has no self-protection mechanism. Criminals often pry open the charging pile equipment to steal electricity and damage it.

[0059] An embodiment of the present invention provides an anti-theft charging method and device for a charging pile device, which is used to solve the technical problem that the existing technology prevents the charging pile device from being maliciously stolen by setting an anti-theft box and an alarm at the charging pile device, but when criminals directly steal the power supply at the output end of the charging pile, the charging pile device cannot identify the stolen power, thereby reducing the reliability of the operation of the charging pile device.

[0060] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0061] See also Figure 1 , Figure 1 This is a flowchart of the steps of an anti-theft charging method for a charging pile device provided in Example 1 of the present invention.

[0062] The present invention provides an anti-theft charging method for a charging pile device, which is applied to a charging pile body and an output cable and a dedicated signal line connected to the charging pile body, and includes:

[0063] Step 101: When a determination instruction is received from a terminal, the power data of the charging pile device within a preset time is collected through a dedicated signal line.

[0064] The judgment instruction refers to the charging pile device being equipped with a charging pile status monitoring element for detecting whether the charging pile device is activated. When it is detected that the charging pile device is not activated within a preset time, the terminal sends a corresponding test signal to determine whether the charging pile device is being charged illegally.

[0065] Electric energy data refers to the output current value, output voltage value, input current value, and input voltage value collected by dedicated signal lines.

[0066] In an embodiment of the present invention, when a determination instruction is received from a terminal, the output current value, output voltage value, input current value and input voltage value of the charging pile device within a preset time are collected through a dedicated signal line installed in the output cable.

[0067] Step 102: Calculate the resistance difference of the charging pile equipment using the electric energy data.

[0068] Resistance difference refers to the deviation between the actual resistance value and the nominal resistance value.

[0069] In an embodiment of the present invention, by calculating the first difference between the input voltage value and the output voltage value, and the first multiplication value between the input current value and the standard resistance value, the ratio between the first multiplication value and the first difference is calculated, and the ratio is determined as the resistance difference.

[0070] Step 103 : Determine whether the output cable has defects based on a comparison result between the resistance difference and a preset standard resistance threshold.

[0071] The standard resistance threshold refers to the standard resistance difference of the output cable of the charging pile equipment.

[0072] In an embodiment of the present invention, it is determined whether the resistance difference is greater than or equal to a preset standard resistance threshold. If the resistance difference is greater than or equal to the standard resistance threshold, it is determined that the output cable has a defect. If the resistance difference is less than the standard resistance threshold, it indicates that the output cable does not have a defect.

[0073] Step 104: If it is determined that the output cable does not have defects, the power difference of the charging pile equipment is calculated using the electric energy data.

[0074] In an embodiment of the present invention, if there is no defect in the output cable, the power difference of the charging pile device is calculated by the output current value, input current value, output voltage value and input voltage value within a preset time.

[0075] Step 105: Determine whether to activate an alarm element on the charging pile body based on a comparison result between the power difference value and a preset power difference standard threshold value.

[0076] The alarm element refers to the alarm component installed on the charging pile body, which consists of a warning light, a speaker and a control module.

[0077] The power difference standard threshold refers to the rated power difference of the charging pile equipment when it is not activated.

[0078] In an embodiment of the present invention, it is determined whether the power difference is greater than or equal to the power difference standard threshold. If the power difference is greater than or equal to the power difference standard threshold, it means that the charging pile device is being stolen by criminals and the alarm element on the charging pile body needs to be activated. If the power difference is less than the power difference standard threshold, it means that the charging pile device is operating normally.

[0079] Step 106: If it is determined that the alarm element is activated, the image data at the current moment is collected by the monitoring element on the charging pile body and uploaded to the terminal.

[0080] The monitoring element refers to the monitoring component installed on the charging pile body, which consists of a camera and a picture transmission element.

[0081] In the embodiment of the present invention, when it is determined that the alarm element is activated, the monitoring element on the charging pile body is controlled to collect image data at the current moment and upload the image data to the terminal.

[0082] In an embodiment of the present invention, when a discrimination instruction is received from a terminal, the electric energy data of the charging pile device is collected through a dedicated signal line, and the resistance difference of the charging pile device is calculated through the electric energy data, and a standard resistance threshold is selected to compare with the resistance difference to determine whether the output cable has defects. If it is determined that the output cable does not have defects, the power difference of the charging pile device is calculated through the electric energy data, and a standard power difference threshold is selected to compare with the power difference to determine whether the charging pile device has been stolen. If the charging pile device has been stolen, the alarm element is activated and the monitoring element on the charging pile body is controlled to collect the image at the current moment and upload the image to the terminal. This solves the technical problem that the prior art prevents the charging pile device from being maliciously stolen by setting an anti-theft box and an alarm at the charging pile device, but cannot identify the act of stealing, thereby reducing the reliability of the operation of the charging pile device. By collecting the electric energy data of the charging pile device, it is possible to identify whether the charging pile device has been stolen by criminals in an inactive state, thereby improving the reliability of the operation of the charging pile device.

[0083] See also Figure 2 , Figure 2 This is a flowchart of the steps of an anti-theft charging method for a charging pile device provided in Example 2 of the present invention.

[0084] The present invention provides an anti-theft charging method for a charging pile device, which is applied to a charging pile body and an output cable and a dedicated signal line connected to the charging pile body, and includes:

[0085] Step 201: When a determination instruction is received from a terminal, the power data of the charging pile device within a preset time is collected through a dedicated signal line.

[0086] See also Figure 3 The charging pile equipment includes a charging pile body, an output cable and a dedicated signal line, wherein the output cable is installed on one side of the charging pile body, and the dedicated signal line is installed inside the output cable. When the charging pile equipment is not activated, the input voltage value, output voltage value, input current value and output current value of the output cable can be collected through the always-on signal receiver set on the dedicated signal line.

[0087] In the embodiment of the present invention, when the determination instruction sent by the terminal is received, the power data of the charging pile device within the preset time is collected using a dedicated signal line.

[0088] It should be noted that a human-computer interaction element is provided on the charging pile body. When the user needs to charge, he needs to use a specific charging card or mobile phone application to activate the human-computer interaction element on the charging pile body before charging can be carried out. At the same time, when the human-computer interaction element is in the activated state, an activation signal will be sent to the terminal. The terminal will only issue a judgment instruction if it does not receive the activation signal within the preset time.

[0089] Step 202: Calculate the resistance difference of the charging pile equipment using the electric energy data.

[0090] Furthermore, the electric energy data includes input current value, output current value, output voltage value and input voltage value, and step 202 includes the following sub-steps:

[0091] S11. Calculate a first difference between an input voltage value and an output voltage value.

[0092] In an embodiment of the present invention, after the input current value, output current value, output voltage value and input voltage value of the charging pile device are collected, a first difference between the input voltage value and the output voltage value is calculated.

[0093] S12. Calculate the first product between the input current value and the standard resistance value.

[0094] In the embodiment of the present invention, the first product value between the input current value and the standard resistance value is calculated according to the matching of the output cable model with the corresponding standard resistance value.

[0095] S13. Calculate a first ratio between the first product value and the first difference value, and determine the first ratio as the resistance difference value.

[0096] In the embodiment of the present invention, after the first multiplication value and the first difference value are calculated, a first ratio between the first multiplication value and the first difference value is calculated, and the first ratio is determined as the resistance difference value.

[0097] Step 203: Determine whether the resistance difference is greater than or equal to a preset standard resistance threshold.

[0098] In an embodiment of the present invention, it is determined whether the resistance difference is greater than or equal to a standard resistance threshold of the charging pile device.

[0099] Step 204: If the resistance difference is less than the standard resistance threshold, it is determined that the output cable has no defects.

[0100] In the embodiment of the present invention, when the resistance difference is less than the standard resistance threshold, it indicates that the output cable has no defects.

[0101] Step 205: If the resistance difference is greater than or equal to the standard resistance threshold, it is determined that the output cable has a defect, and the defect data is uploaded to the terminal through the communication component on the charging pile body.

[0102] In an embodiment of the present invention, when the resistance difference is greater than or equal to the standard resistance threshold, it indicates that the output cable is present or disconnected, and the defect data is transmitted to the terminal through the communication element provided on the charging pile body.

[0103] Step 206: If it is determined that the output cable does not have defects, the power difference of the charging pile equipment is calculated using the electric energy data.

[0104] Further, step 206 is specifically as follows:

[0105] If it is determined that the output cable does not have defects, the power data is input into a preset power difference function to calculate the power difference value of the charging pile device;

[0106] The power difference function is specifically:

[0107]

[0108] Among them, U r is the input voltage value, U c is the output voltage value, I r is the input current value, I c is the output current value, T is the superposition time, and Q is the power difference.

[0109] In an embodiment of the present invention, when it is determined that the output cable does not have defects, the electric energy data within a preset time is input into a power difference function of a threshold value to calculate the power difference value of the charging pile device.

[0110] It should be noted that the power difference function generally selects the input current value, output current value, input voltage value and output voltage value of 5 to 10 seconds.

[0111] Step 207: Determine whether to activate the alarm element on the charging pile body based on the comparison result between the power difference value and the preset power difference standard threshold value.

[0112] Furthermore, step 207 includes the following sub-steps:

[0113] S21. Determine whether the power difference is greater than or equal to a preset power difference standard value.

[0114] In the embodiment of the present invention, when the power difference value is calculated, it is determined whether the power difference value is greater than or equal to a preset power difference standard value.

[0115] S22: If the power difference is greater than or equal to the power difference standard value, it is determined to activate the alarm element on the charging pile body.

[0116] In an embodiment of the present invention, if the power difference is greater than or equal to the power difference standard value, it means that the charging pile device is outputting electric energy in an inactive state, and it is determined that the charging pile device has stolen electricity and the alarm element on the charging pile body is activated.

[0117] It should be noted that the alarm component can also receive a feedback instruction from the terminal. When the alarm component receives the feedback instruction, it stops the sound and light alarm.

[0118] S23. If the power difference is less than the power difference standard value, it is determined that the charging pile equipment is operating normally.

[0119] In the embodiment of the present invention, when the power difference value is less than the power difference standard value, it indicates that the charging pile device is not outputting electric energy in the inactivated state, and it is determined that the charging pile device is operating normally.

[0120] Step 208: If it is determined that the alarm element is activated, the image data at the current moment is collected by the monitoring element on the charging pile body and uploaded to the terminal.

[0121] In the embodiment of the present invention, when it is determined that the alarm element is activated, the image data at the current moment is collected by the monitoring element provided on the charging pile body and uploaded to the terminal.

[0122] It should be noted that when the monitoring component collects image data at the current moment, the image data can also be input into the trained neural network model for recognition to determine whether the image data collected at the current angle can actually recognize the face. If not, the image data will continue to be collected by adjusting the angle of the camera. If so, the collected data will be uploaded to the terminal.

[0123] In an embodiment of the present invention, when the terminal does not receive the activation signal sent by the charging pile device within a preset time, a judgment instruction is sent to the charging pile device. When the charging pile device receives the judgment instruction, the electric energy data of the charging pile device within the preset time is collected through a dedicated signal line, and the electric energy data is used to calculate the resistance difference of the charging pile device, and the resistance difference is compared with the preset standard resistance threshold to determine whether the output cable has a defect. If the output cable has a defect, the defect data is uploaded to the terminal through the communication element on the charging pile. If the output cable does not have a defect, the electric energy data is input into the power difference function to calculate the power difference of the charging pile device, and the power difference is compared with the preset power difference standard threshold to determine whether to start the alarm element on the charging pile body. If the power difference is less than the power difference standard value, it is determined that the charging pile device is operating normally. If the power difference is greater than or equal to the power difference standard value, the alarm element is determined and the image data at the current moment is collected through the monitoring element on the charging pile body and uploaded to the terminal. This solves the technical problem that existing technologies, which prevent malicious theft of charging piles by installing anti-theft boxes and alarms on charging piles, cannot identify unauthorized charging, thus reducing the reliability of the charging piles. By collecting power data from charging piles, it can identify whether the charging piles are being unauthorizedly charged while in an inactive state, thereby improving the reliability of the charging piles.
