[0082] like Figure 2 , Figure 6 and Figure 7 As shown, the distance between the identification component 3 and the transmitting end component 2 is fixed, so that the identification component 3 can be installed in close contact with the transmitting end component 2.

The receiving end mark 8 is used to identify the size and position of the receiving coil in the receiving end.

[0084] Based on the above wireless charging device, this embodiment provides a wireless charging management control method.

[0085] like Fig. 9 As shown, a wireless charging management control method provided by an embodiment of the present invention is based on a wireless charging device, wherein the wireless charging device comprises a transmitting end component 2, an identification component 3 and a rear wheel adjustment component 4 arranged in sequence along a first direction of a charging position; the identification component 3 is used to identify the position of a receiving end installed on an electric vehicle, the transmitting end component 2 comprises a transmitting end, and the transmitting end is used to identify a code of the receiving end, and the method comprises:

[0086] S1: When the transmitting end of the charging position recognizes the code of the receiving end, multiple components in the wireless charging device in the charging position are controlled to be powered on and in standby mode, wherein each receiving end has a unique code.

[0087] Specifically, the receiving end can be installed under the pedal of the electric vehicle. When the electric vehicle is pushed into the charging position, the receiving end on the electric vehicle gradually approaches the transmitting end. Each receiving end has a unique RXSN code (equivalent to the identity code of the receiving end, which is used to identify the identity information of the receiving end in wireless communication). When the user performs wireless charging for the first time, the code on the receiving end can be picked up to register an account and bound to the user's user terminal or mobile terminal. Recharge can be performed in the registered account. After that, when wireless charging is performed, the account corresponding to the receiving end can be automatically identified, and the charging fee can be deducted from the corresponding account, so as to avoid the user terminal frequently opening the mobile terminal for charging operations. When the electric vehicle enters the charging position, within a certain range, the transmitting end can automatically identify the coding information of the receiving end in advance. Although the electric vehicle is not fully in place, the transmitting end component 2, the identification component 3 and the rear wheel adjustment component 4 and other components or electronic components in the wireless charging device in the charging position can be controlled in advance to be powered on and standby. At this time, all other electronic components except the transmitting coil are controlled to be powered on.

[0088] S2: When the front wheels of the electric vehicle reach a preset position, determining whether the electric vehicle is centrally parked.

[0089] S3: When the electric vehicle is not parked in the center, the rear wheel adjustment assembly 4 is controlled to operate to adjust the rear wheel position of the electric vehicle until the electric vehicle is parked in the center.

[0090] When installing the transmitter assembly 2, the transmitting coil in the transmitter assembly 2 is installed in the center. The center installation means that the center line of the transmitting coil is aligned with the center line of the receiving groove of the wheel positioning member 1 (such as Figure 1 The dotted line in the figure overlaps, so the receiving end on the electric vehicle also needs to be centered. When installing the receiving end, the receiving end is installed in the center of the left and right sides of the electric vehicle. When the electric vehicle is not parked in the center, the transmitting coil and the receiving coil are not aligned in the width direction of the charging position. Since the front wheel of the electric vehicle will be pushed into the wheel positioning member 1, the front wheel is already guaranteed to be centered. It is necessary to control the operation of the rear wheel adjustment component 4 to adjust the position of the rear wheel. After the rear wheel is centered, the entire electric vehicle is considered to be parked in the center. When the electric vehicle is parked in the center, the transmitting coil and the receiving coil are aligned in the width direction of the charging position.

[0091] S4: When the electric vehicle is parked in the center, the location information of the receiving end of the electric vehicle uploaded by the identification component 3 is obtained.

[0092] Specifically, when the transmitter at the charging station recognizes the code of the receiver, the identification component 3 is energized. When the receiver on the electric vehicle passes through the identification component 3, the identification component 3 recognizes the receiver mark 8 and the trailing mark 9 on the surface of the receiver, thereby being able to analyze the location information of the receiver.

[0093] S5: According to the position information of the receiving end, the transmitting end component 2 is controlled to operate so that the transmitting coil in the transmitting end component 2 is aligned with the receiving coil in the receiving end.

[0094] Specifically, according to the position information of the receiving end, the screw rod 23 in the transmitting end assembly 2 is controlled to rotate. The nut 26 and the transmitting end 21 on the nut 26 are initially located in the middle position of the screw rod 23. Since the positional relationship between the transmitting end assembly 2 and the identification assembly 3 is fixed, after the position information of the receiving end is obtained based on the identification assembly 3, the transmitting end 21 can be controlled to be aligned with the receiving end. At this time, the receiving coil and the transmitting coil are aligned in the length direction of the charging position.

[0095] S6: When the transmitting coil is aligned with the receiving coil, the transmitting coil is controlled to be energized to charge the electric vehicle through the receiving coil.

[0096] In this embodiment, when the transmitter of the charging position recognizes the code of the receiver, the wireless charging device in the charging position is controlled to be powered on, so as to monitor the position of the electric vehicle and the position of the receiver during the process of the electric vehicle entering the charging position. When the front wheel of the electric vehicle reaches the preset position, for example, the front wheel enters the accommodating cavity of the wheel positioning member 1 and the left side wall of the accommodating cavity (such as Figure 1When the electric vehicle is not parked in the center, the rear wheel adjustment component 4 is controlled to operate to adjust the rear wheel position of the electric vehicle. When the rear wheel is also in the center, the electric vehicle is parked in the center. First, the transmitting coil and the receiving coil are aligned in the width direction of the charging position. When the electric vehicle is parked in the center, the position information of the receiving end of the electric vehicle uploaded by the identification component 3 is obtained. According to the position information of the receiving end, the transmitting end component 2 is controlled to operate, and then the receiving coil and the transmitting coil are aligned in the length direction of the charging position, so that the receiving coil and the transmitting coil are completely aligned. When the transmitting coil is aligned with the receiving coil, the transmitting coil is controlled to be energized to charge the receiving coil, thereby improving the wireless charging efficiency and realizing automatic adjustment of the transmitting coil and the receiving coil.

[0097] Optionally, when the front wheel of the electric vehicle reaches a preset position, determining whether the electric vehicle is centrally parked includes:

[0098] When the pressure signal uploaded by the pressure sensor 6 is received, it is determined that the front wheel of the electric vehicle has reached a preset position, wherein the wireless charging device also includes a pressure sensor 6 and a wheel positioning member 1, wherein the wheel positioning member 1 is used to limit the position reached by the front wheel of the electric vehicle, and the pressure sensor 6 is installed on the wheel positioning member 1 to monitor whether the front wheel of the electric vehicle has completely entered the wheel positioning member 1.

[0099] Specifically, when the front wheel squeezes the pressure sensor 6, it means that the front wheel completely enters the wheel positioning member 1 and reaches the preset position. At this time, the pressure sensor 6 uploads a pressure signal.

[0100] When the front wheel of the electric vehicle reaches a preset position, the transmitting coil is controlled to be energized for a preset time, and the real-time charging efficiency of the receiving coil is detected and obtained.

[0101] Specifically, wireless communication can be carried out between the transmitter and the receiver. When charging, the battery power of the receiver is monitored in real time. The receiver is first charged for a trial period of less than 1 minute to obtain the battery power growth situation, thereby analyzing the real-time charging efficiency.

[0102] It is determined whether a difference between the alignment charging efficiency of the receiving coil and the real-time charging efficiency is greater than a preset difference, wherein the alignment charging efficiency is the charging efficiency of the receiving coil detected when the transmitting end is aligned with the receiving end.

[0103] When the difference between the alignment charging efficiency and the real-time charging efficiency is less than or equal to the preset difference, it is determined that the electric vehicle is centrally parked.

[0104] When the difference between the alignment charging efficiency and the real-time charging efficiency is greater than the preset difference, it is determined that the electric vehicle is not centrally parked.

[0105] Specifically, the charging efficiency when the transmitting coil and the receiving coil are aligned is detected in advance, and this efficiency is used as the alignment charging efficiency. When the real-time charging efficiency deviates greatly from the alignment charging efficiency, it means that the misalignment between the receiving coil and the transmitting coil is serious, indicating that the electric vehicle may not be parked in the center, and the position of the electric vehicle needs to be adjusted first, that is, the position of the receiving coil needs to be adjusted. When the real-time charging efficiency deviates little from the alignment charging efficiency, it means that the electric vehicle is parked in the center and the parking position is good. At this time, the rear wheel of the electric vehicle does not need to be adjusted, and the user can leave the charging position.

[0106] Optionally, the wireless charging device further comprises a position sensor 7, which is installed in the charging position and located between the rear wheel adjustment component 4 and the identification component 3, and the position sensor 7 is located on the extension line of the center line of the wheel positioning member 1, and is used to monitor the rear wheel position of the electric vehicle;

[0107] When the electric vehicle is not parked in the center, controlling the rear wheel adjustment assembly 4 to operate to adjust the rear wheel position of the electric vehicle until the electric vehicle is parked in the center includes:

[0108] When the electric vehicle is not parked in the center, it is monitored whether a trigger signal uploaded by the position sensor 7 is obtained.

[0109] Specifically, when the position sensor 7 is not blocked by the rear wheel, the position sensor 7 does not output a signal, and when the position sensor 7 is blocked by the wheel, the position sensor 7 outputs a trigger signal.

[0110] When the trigger signal uploaded by the position sensor 7 is not obtained, the rear wheel adjustment component 4 is controlled to run forward, and the first running time of the rear wheel adjustment component 4 is monitored. Fig.10 In part a and part b, in this case, the rear wheels on the rear wheel adjustment assembly 4 do not block the position sensor 7, and the position sensor 7 will not upload a trigger signal.

[0111] When the first running time is greater than the first preset time and the trigger signal uploaded by the position sensor 7 is not received, the rear wheel adjustment component 4 is controlled to run in reverse; when the trigger signal uploaded by the position sensor 7 is received, the timing starts, and the rear wheel adjustment component 4 is continuously controlled to run in reverse until the trigger signal disappears, and the rear wheel adjustment component 4 is controlled to stop running to obtain the trigger signal duration.

[0112] Specifically, Fig.10As shown in part a of the figure, the direction indicated by the arrow is the positive direction. When the rear wheel adjustment component 4 runs forward, it will only cause the rear wheel to move further and further away from the position sensor 7. Generally, when the front wheel completely enters the wheel positioning member 1, the deviation distance of the rear wheel will not be too large. If it moves normally, it can block the position sensor 7 again within the first preset time. When the first running time is greater than the first preset time and no trigger signal is received, it means that the running direction of the rear wheel adjustment component 4 is wrong. At this time, let the rear wheel adjustment component 4 run in the reverse direction until the position sensor 7 uploads the trigger signal. When the position sensor 7 uploads the trigger signal, it means that the rear wheel has just blocked the position sensor 7. When the trigger signal disappears, it means that the rear wheel has just moved away from the position sensor 7. The time between the two is the time that the rear wheel continues to block the position sensor 7, that is, the trigger signal duration. Since the running speed of the rear wheel adjustment component 4 is known, the width of the rear wheel can be calculated.

[0113] When the first running time is less than or equal to the first preset time and a trigger signal uploaded by the position sensor 7 is received, timing starts, and the rear wheel adjustment component 4 is continuously controlled to run forward until the trigger signal disappears, and the rear wheel adjustment component 4 is controlled to stop running to obtain the trigger signal duration.

[0114] Specifically, Fig.10 As shown in part b, when the rear wheel adjustment assembly 4 runs forward, the position sensor 7 will upload a trigger signal within the first preset time, and the time from the appearance to the disappearance of the trigger signal is exactly the blocking time of the rear wheel.

[0115] When the trigger signal uploaded by the position sensor 7 is obtained, the rear wheel adjusting component 4 is controlled to run in the forward direction; when the trigger signal disappears, the rear wheel adjusting component 4 is controlled to run in the reverse direction; when the trigger signal is received again, the timing is started, and the rear wheel adjusting component 4 is continuously controlled to run in the reverse direction until the trigger signal disappears again, and the rear wheel adjusting component 4 is controlled to stop running to obtain the trigger signal duration.

[0116] Specifically, Fig.10 As shown in part c, when the position sensor 7 uploads the trigger signal at the beginning, the specific position and size of the rear wheel are unknown at this time, and the rear wheel cannot be adjusted to the center. At this time, the rear wheel adjustment component 4 can be allowed to run forward. When the trigger signal of the position sensor 7 disappears, the rear wheel has just left the position sensor 7, and the edge of the rear wheel is located. Then the rear wheel adjustment component 4 is controlled to run in the reverse direction, and a complete trigger signal duration can be obtained.

[0117] According to the duration of the trigger signal, the rear wheel adjusting component 4 is controlled to run in a direction opposite to that of the rear wheel adjusting component 4 during the timing process, and the running time is half of the duration of the trigger signal.

[0118] Specifically, in the above-mentioned various operating conditions, the moment when the rear wheel does not block the position sensor 7 is finally achieved, and the rear wheel adjustment component 4 is controlled to stop operating. At this time, the reverse operation is performed for half the duration of the trigger signal, which just adjusts the rear wheel to the center, thereby realizing automatic measurement of the rear wheel width and automatic adjustment of the rear wheel to the center position, thereby improving the adjustment accuracy.

[0119] Alternatively, if Figure 6 and Figure 8 As shown, the identification component 3 is attached to the transmitting end component 2, and the identification component 3 includes a plurality of laser probes 32, and the plurality of laser probes 32 are arranged on the same straight line, and the connecting line of the plurality of laser probes 32 is perpendicular to the first direction, wherein, Figure 1 As shown, the first direction is the length direction of the charging position, the identification component 3 is centrally installed in the charging position, the surface of the receiving end of the electric vehicle is covered with a receiving end logo 8, and the end of the receiving end logo 8 close to the rear wheel of the electric vehicle is connected to a tailing logo 9, the width of the receiving end logo 8 is greater than the width of the tailing logo 9, and the receiving end logo 8 and the tailing logo 9 are respectively divided into multiple white logo areas and multiple black logo areas.

[0120] When the electric vehicle is centrally parked, obtaining the location information of the receiving end of the electric vehicle uploaded by the identification component 3 includes:

[0121] When the electric vehicle is parked in the center, the detection signals uploaded by the multiple laser probes 32 are obtained, wherein the laser probe 32 obtains different detection signals when detecting the white area and the black area, for example, the laser probe 32 uploads a low level when detecting the white area, and uploads a high level when detecting the black area. The widths of the white area and the black area can be set to a standard width d, and the number of high and low levels uploaded by the laser probe 32 can be counted to obtain the size of the receiving end.

[0122] According to the detection signals uploaded by the plurality of laser probes 32 , the length of the receiving end mark 8 and the positioning length of the trailing mark 9 passing through the identification component 3 are obtained.

[0123] Specifically, since the width of the receiving end mark 8 is greater than the width of the trailing mark 9, the number of laser probes 32 with signal changes is relatively large in the early detection period. Figure 6The detection signals uploaded by the seven laser probes 32 shown are constantly changing, but when the receiving end mark 8 passes over the identification component 3, the trailing mark 9 enters the detection range of the identification component 3, and the detection signals of the laser probes 32 at both ends of the identification component 3 may remain at a low level, while the detection signals of the two or three laser probes in the middle still maintain a high and low level alternating state. Therefore, the total number of high and low levels between the time points when the laser probes 32 at both ends appear at a high level and maintain a low level can be counted, multiplied by the standard width d, to obtain the length of the receiving end mark 8. Then, from the time point when the laser probes 32 at both ends maintain a low level to the time when the pressure sensor 6 uploads the pressure signal, the number of high and low levels in the detection time period is counted to obtain the positioning length. It is possible that the last identification area cannot completely cross the identification component 3. At this time, the length of the detection time period for the trailing mark 9 to enter the identification component 3 can be subtracted from the total time occupied by the complete high level and low level to obtain the moving time of the last identification area. According to the total time occupied by the complete high and low levels corresponding to the trailing mark 9 and the length of the complete high and low levels, the average speed is measured. According to the moving time and average speed of the last identification area, the width of the last identification area entering the detection range of the identification component 3 is obtained, recorded as the incomplete width. The total number of complete high levels and low levels corresponding to the trailing mark 9 is multiplied by the standard width d, and then added to the incomplete width to obtain a more accurate positioning length, thereby improving the positioning accuracy and making the charging efficiency higher.

[0124] According to the length of the receiving end identifier 8 and the positioning length, the relative position information of the receiving end with respect to the identification component 3 is obtained.

[0125] Specifically, the positioning length and the length of the receiving end identifier 8 can calculate the distance between the center of the receiving end and the identification component 3, thereby obtaining relative position information.

[0126] Optionally, the wireless charging device further includes two ranging probes 5, which are respectively installed at the same height in the wheel locating member 1, and when the front wheel of the electric vehicle enters the wheel locating member 1, the two ranging probes 5 are located on both sides of the front wheel.

[0127] After the electric vehicle is centrally parked, the wireless charging management control method further includes:

[0128] The distance information uploaded by the two ranging probes 5 is obtained.

[0129] The tilt angle of the electric vehicle is obtained according to the absolute difference of the distance information uploaded by the two distance measuring probes 5 and the height information of the distance measuring probe 5 .

[0130] Specifically, after the electric vehicle is parked in the center, if the electric vehicle is parked vertically, the distances from the two distance measuring probes 5 to the side wall of the front wheel should be equal. The two distance measuring probes 5 measure their distances from the front wheel respectively, and the tilt angle can be approximately obtained according to the absolute difference of the two distance information and the height information of the distance measuring probes 5 based on the principle of trigonometric function.

[0131] Optionally, controlling the transmitter component 2 to operate according to the position information of the receiver so that the transmitter coil in the transmitter component 2 is aligned with the receiver coil in the receiver includes:

[0132] According to the relative position information, the position adjustment member in the transmitter assembly 2 is controlled to work so that the center of the transmitter coincides with the center of the receiving end, wherein the position adjustment member is connected to the transmitter and is used to adjust the position of the transmitter. Figure 4 As shown, the position adjustment member may be a driving source connected to the screw rod 23 , such as a stepping motor for driving the screw rod 23 to rotate.

[0133] According to the tilt angle of the electric vehicle, the angle adjustment member in the transmitting end assembly 2 is controlled to work, and the lifting member 22 moves so that the tilt angle of the transmitting end is the same as the tilt angle of the electric vehicle, wherein the angle adjustment member is connected to the transmitting end and is used to adjust the tilt angle of the transmitting end. Figure 4 and Figure 5 As shown, the angle adjustment member may be a lifting member 22, and the lifting member 22 may be a lifting member that can be extended or retracted, such as an electric telescopic rod, a gas cylinder or an oil cylinder.

[0134] Specifically, the screw rod 23 in the transmitting end assembly 2 can be controlled to rotate according to the relative position information so that the center of the receiving coil coincides with the center of the transmitting coil. At this time, the charging efficiency can be greatly improved. However, since some electric vehicles use side support feet to park, the body of the electric vehicle tilts, which in turn tilts the receiving end, and the receiving coil installed in the receiving end also tilts accordingly. At this time, the lifting member 22 can be further controlled to lift according to the tilt angle, so that one side of the support plate 24 is lifted, such as Figure 5 According to the vertical distance L between the lifting member 22 and the connecting rod 27 and the inclination angle, the lifting distance of the lifting member 22 can be calculated. By controlling the lifting of the lifting member 22, the transmitting coil and the receiving coil can be kept parallel, so that the magnetic flux in the receiving coil reaches the maximum, further improving the charging efficiency.

[0135] Optionally, when the transmitting coil is aligned with the receiving coil, controlling the transmitting coil to be energized so as to charge the electric vehicle through the receiving coil comprises:

[0136] When the transmitting coil is aligned with the receiving coil, the user's account is queried according to the code of the receiving end, wherein the code of each receiving end is bound to at least one of the user's accounts.

[0137] When the account balance of the user meets the charging condition, the transmitting coil is controlled to be energized.

[0138] Specifically, since the code of the receiving end is bound to the user's personal account when used for the first time, the user's account can be automatically queried through the code of the receiving end. When the user's account balance is greater than the preset amount, such as 0.5 yuan, it can be automatically charged and the transmitting coil can be controlled to be energized. When the account balance is less than or equal to the preset amount, a reminder message can be sent to the user end. When the user continues to charge through the user end feedback, charging is performed to ensure that the user's account balance can support the charging expenses that may be deducted. It can also be further configured that when the account balance is less than or equal to the preset amount, the allowed charging time is obtained according to the account balance, and then the charging time is monitored. When the charging time reaches the allowed charging time, charging is automatically stopped.

[0139] Optionally, when the transmitting coil is aligned with the receiving coil, the transmitting coil is controlled to be powered on so as to charge the electric vehicle through the receiving coil, the wireless charging management control method further includes:

[0140] When the electric vehicle finishes charging, the charging fee is obtained according to the charging time or charging amount of the electric vehicle.

[0141] Specifically, the charging fee can be calculated using two billing methods, one is charging time billing, and the other is charging power billing.

[0142] At the same time, a vehicle moving notification is sent to the user, and the timing is started to obtain the occupied time information.

[0143] The occupancy fee is obtained according to the occupancy time information and the preset charging conditions, wherein the preset charging conditions include multiple time periods and multiple charging unit prices, and the multiple time periods correspond to the multiple charging unit prices one by one.

[0144] A total fee is obtained according to the charging fee and the seat occupancy fee.

[0145] Specifically, since the charging position is designed for charging electric vehicles, in order to avoid long-term occupation of the charging position, a vehicle moving notification can be sent to the owner of a fully charged electric vehicle, and no charge may be charged for a certain period of time after the notification is sent, for example, it is free within two hours after the notification is sent, and the occupancy fee will be calculated after two hours. In order to encourage users to actively move their vehicles, the charging time periods are differentiated on the basis of charging, with more charges during the peak time period of possible wireless charging equipment use and less charges during the off-peak time period of wireless charging equipment use. Since it is impossible to move the vehicle in time after fully charging at night, it can be further humanized to set up no occupancy fee at night.

[0146] Optionally, the method for setting the preset charging conditions includes:

[0147] According to the acquired operation data of all wireless charging devices, the usage quantity of the wireless charging devices in each time period is obtained, wherein a day is divided into a plurality of the time periods.

[0148] The device usage rate of each time period is obtained according to the number of wireless charging devices used in each time period and the total number of wireless charging devices. For example, the device usage rate is obtained by dividing the number of wireless charging devices used in each time period by the total number of wireless charging devices.

[0149] A designated time period among the multiple time periods is used as a free time period, and other time periods among the multiple time periods excluding the free time period are used as pending time periods, wherein the charging unit price corresponding to the free time period is zero.

[0150] Determine whether the device usage rate corresponding to the pending time period is greater than a preset usage rate.

[0151] When the device usage rate corresponding to the pending time period is greater than the preset usage rate, the pending time period is regarded as a peak time period, wherein the charging unit price corresponding to the peak time period is a peak unit price.

[0152] When the equipment usage rate in the pending time period is less than or equal to the preset usage rate, the pending time period is regarded as a valley time period, wherein the charging unit price corresponding to the valley time period is the valley unit price, and the peak unit price is higher than the valley unit price.

[0153] Specifically, if the user does not move the electric vehicle after a certain period of time, such as 2 hours, after being fully charged, the user will be charged according to the situation. The charges are divided into the following situations: free time period, such as from 22:00 at night to 08:00 the next day, no charge; peak charging time period, such as from 17:00 to 22:00 in the afternoon, the charging unit price is a; low charging time period, such as from 8:00 in the morning to 12:00 noon, and from 3:00 to 5:00 in the afternoon, the charging unit price is b.

[0154] For the division of time periods, the number of charging devices used in each time period is counted, ki, where i represents the serial number of the time period, i=1, 2...n; the charging device utilization rate pi in each time period is calculated, that is, the ratio of the number of wireless charging devices used in a certain time period to the total number of wireless charging devices m, pi=ki / m; according to the charging device utilization rate obtained by analysis, the charging unit price for each time period is determined; for example, the free time period is removed, and the time period with pi>0.5 is recorded as the peak time period, and the time period with pi≤0.5 is recorded as the valley time period. Data statistical analysis can be performed periodically to dynamically adjust whether the time period belongs to the peak period or the valley period, so as to motivate users to move their cars in time, increase the income brought by wireless charging equipment, and promote the popularization of wireless charging methods.

[0155] Optionally, the wireless charging management control method further includes:

[0156] When the battery of the electric vehicle is not completely charged, but it is detected that the electric vehicle is moved out of the charging position, the camera device on the charging position is controlled to capture an image of the person moving the vehicle.

[0157] Specifically, the battery power information can be obtained through wireless communication between the receiving end and the transmitting end. When the car is moved before the battery is fully charged, the camera device can be controlled to take a snapshot, so as to monitor the behavior of moving the car without reason or deliberately occupying other people's charging positions.

[0158] According to the image of the person moving the vehicle, it is determined whether the person moving the vehicle is the owner of the electric vehicle.

[0159] Specifically, when registering an account for the first time, with the user's consent, the user can choose to upload photos of the user and other people allowed by the user, such as profile pictures of the user and his or her family, for easy supervision.

[0160] When the person moving the vehicle is not the owner of the electric vehicle, an alarm message is sent to the user terminal corresponding to the electric vehicle.

[0161] Specifically, through face recognition, it can be determined whether the person moving the vehicle is the user himself or someone related to the user (both are determined to be the vehicle owner). If the person moving the vehicle is the owner of the electric vehicle, no reminder will be given, the vehicle will be automatically powered off and the charging fee will be settled. If the person moving the vehicle is not the owner of the electric vehicle or the user photo of the owner is not found, an alarm message will be sent to the user end of the owner to remind the user that his electric vehicle has been moved without reason.

[0162] In response to the warning instruction fed back by the user end, the speaker device on the charging position is controlled to play a reminder voice, or the client corresponding to the car mover is located according to the image of the car mover, and a reminder message is sent to the client of the car mover, wherein the reminder voice or the reminder message is used to remind the car mover not to move other people's vehicles.

[0163] Specifically, the acquired image information is not sent to any user, but only an alarm message or a reminder message is sent to the user end. After a period of time, the acquired image is automatically deleted and is not stored for a long time.

[0164] In this embodiment, the charging behavior of users can be monitored by video, so as to prevent electric vehicles that are not fully charged from being moved away by non-owners, and ensure that electric vehicles that are being charged can be fully charged normally.

[0165] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
