CROSS-REFERENCE TO RELATED APPLICATION 
     The present application claims priority to Korean Patent Application No. 10-2021-0151062, filed Nov. 5, 2021, the entire contents of which is incorporated herein for all purposes by this reference. 
     BACKGROUND OF THE PRESENT DISCLOSURE 
     Field of the Present Disclosure 
     The present disclosure relates to an electric moving object of guiding a situation of wireless charging and a method using the same, and more particularly, to an electric moving object guiding a wireless charging situation, in which the charging progress state of a moving object and various situations may be easily checked, and a method using the same. 
     Description of Related Art 
     The electric vehicle is a moving object driven by electricity as power supply. A battery capable of charging power source is mounted in an electric vehicle itself, and the electric vehicle may be driven by power supply of the battery. 
     There are currently two conventional types of charging electric vehicles: plug-in (or cabled) charging, which directly connects an electric vehicle to a commercial power source through a charging line, and wireless charging. Compared with plug-in charging, wireless charging may not only be provided in various places free from spatial limitations but also prevent the poor charging state of the cabled method because no contact is exposed and such a risky situation as short circuit does not actually occur. 
     The wireless charging method charges a battery by making a current flow through electromagnetic induction. Herein, power may be supplied as a magnetic field generated at a transmission pad, which functions as a power supply unit, is induced to a reception pad connected to the battery. As the wireless charging method does not include any direct connection like in the cabled method, a poor charging state may occur frequently because of the misalignment between pads or other external environments like neighboring objects and weather. For high charging efficiency, a technique is needed for a user to check and handle more rapidly various types of situations which are likely to happen in charging a vehicle. 
     The information included in this Background of the present disclosure section is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to various embodiments of the present disclosure(s), examples of which are illustrated in the accompanying drawings and described below. While the present disclosure(s) will be described in conjunction with exemplary embodiments of the present disclosure, it will be understood that the present description is not intended to limit the present disclosure(s) to those exemplary embodiments of the present disclosure. On the other hand, the present disclosure(s) is/are intended to cover not only the exemplary embodiments of the present disclosure, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the present disclosure as defined by the appended claims. 
     Hereinafter, various exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present disclosure. However, the present disclosure may be implemented in various different ways, and is not limited to the exemplary embodiments described therein. 
     In describing exemplary embodiments of the present disclosure, well-known functions or constructions will be omitted in detail since they may unnecessarily obscure the understanding of the present disclosure. The same constituent elements in the drawings are denoted by the same reference numerals, and a repeated description of the same elements will be omitted. 
     In the present disclosure, when an element is simply referred to as being “connected to”, “coupled to” or “linked to” another element, this may mean that an element is “directly connected to”, “directly coupled to” or “directly linked to” another element or is connected to, coupled to or linked to another element with the other element intervening therebetween. Furthermore, when an element “includes” or “has” another element, this means that one element may further include another element without excluding another component unless stated otherwise. 
     In the present disclosure, the terms first, second, etc. are only used to distinguish one element from another and do not limit the order or the degree of importance between the elements unless specifically mentioned. Accordingly, a first element in an exemplary embodiment could be termed a second element in another exemplary embodiment of the present disclosure, exemplary embodiment of the present disclosure, and similarly, a second element in an exemplary embodiment could be termed a first element in another exemplary embodiment of the present disclosure, exemplary embodiment of the present disclosure, without departing from the scope of the present disclosure. 
     In the present disclosure, elements that are distinguished from each other are for clearly describing each feature, and do not necessarily mean that the elements are separated. That is, a plurality of elements may be integrated in one hardware or software unit, or one element may be distributed and formed in a plurality of hardware or software units. Therefore, even if not mentioned otherwise, such integrated or distributed embodiments are included in the scope of the present disclosure. 
     In the present disclosure, elements described in various embodiments do not necessarily mean essential elements, and some thereof may be optional elements. Therefore, an exemplary embodiment including a subset of elements described in an exemplary embodiment of the present disclosure is also included in the scope of the present disclosure. Furthermore, embodiments including other elements in addition to the elements described in the various embodiments are also included in the scope of the present disclosure. 
     The advantages and features of the present disclosure and the way of attaining them will become apparent with reference to various exemplary embodiments described below in detail. Embodiments, however, may be embodied in various forms and may not be constructed as being limited to example embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be complete and will fully convey the scope of the present disclosure to those skilled in the art. 
     Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. 
       FIG.  1    is a view schematically illustrating an electric moving object, a gas charging device, a user device and a server communicating therewith. 
     An electric moving object  100  may be charged wirelessly by electric power from a wireless charging device  200 . The electric moving object  100  may generate data associated with information on a charging situation which notifies a progress state related to a charging operation and an obstacle element and transmit the data to a server  300 , and the server  300  may transmit the information on the charging situation based on the data to a user device  400 . Furthermore, the electric moving object  100  may process information on a charging situation based on the data and provide the information on the charging situation to a display  114  so that the display  114  may display the information. Hereinafter the description will be presented mainly through an example of generating, by the server  300 , information on a charging situation based on the data, but is not limited thereto. As an exemplary embodiment of the present disclosure, the moving object  100  may generate information on a charging situation on its own and transmit the information on the charging situation to the user device  400  with no intervention of the server  300  but by communicating directly with the user device  400 . As yet another example, the moving object  100  may transmit information on a charging situation, and the information on the charging situation may be transmitted to the user device  400  via the server  300  to monitor charging states of various moving objects and identify obstacle types. 
     For example, the electric moving object  100  may move by use of the power of a battery  102  as a driving source and may refer to a device of which the battery  102  may be charged at least by wireless charging. The moving object  100  may be a vehicle, a personal mobility, a mobile office, or a mobile hotel. The vehicle may be a four-wheel car, for example, a sedan, a sports utility vehicle (SUV), and a pickup truck and may also be a vehicle with five or more wheels, for example, a lorry, a container truck, and a heavy vehicle. Once the moving object  100  may be driven by the battery  102  which is charged wirelessly, it may be an aerial moving object, apart from a ground moving object, for example, a drone and a personal aerial vehicle (PAV). The moving object  100  may be embodied by manned driving or autonomous driving (either semi-autonomous or full-autonomous driving). Hereinafter, for convenience of explanation, the description utilizes an example vehicle as a ground moving object but is not limited thereto, and various other types of moving objects may be applied. The moving object  100  may communicate with another device or another moving object. As an exemplary embodiment of the present disclosure, the moving object  100  may communicate with another device based on cellular communication, WAVE communication, Dedicated Short-Range Communication (DSRC) and other communication schemes. That is, as a cellular communication network, a communication network such as LTE, 5G, WiFi communication network, WAVE communication network, etc. may be used. Furthermore, a local area network used in a moving object, such as DSRC may be used, and the present disclosure is not limited to the above-described embodiment. Thus, for example, the moving object  100  may exchange data with the user device  400  and the wireless charging device  200  through short range communication and transmit and receive signals to or from the server  300  through cellular or WAVE communication. 
     The wireless charging device  200  may have a power transmission module unit  210 , which is aligned with a power reception module unit  106  of the moving object  100  and supplies energy, a supply line  220 , which supplies energy to the power transmission module unit  210 , and a control panel  230  that controls energy supply through the supply line  220  and has a charge function. The power transmission module unit  210  may be located on the ground surface or be configured as a pad type, which is fixed in part on the ground surface and exposed in part, but is not limited thereto and may have any form capable of wirelessly charging the power reception module unit  106 . Though not shown in the drawing, the wireless charging device  200  may include a detector for detecting an abnormal situation of the power transmission module unit  210 . For example, the detector may detect whether or not there is an object on the power transmission module unit  210  and may detect an impact caused by a physical force of an external object. Accordingly, the detector may generate data of an abnormal situation which is associated with the presence of an object and an impact. As an exemplary embodiment of the present disclosure, the detector may be an object recognition detector, a pressure detector and an image detector which are embedded in the power transmission module unit  210 . As an exemplary embodiment of the present disclosure, the detector may be an image detector which is provided in a location distant from the power transmission module unit  210 . 
     Although not shown in the drawing, the wireless charging device  200  may include a module configured for communicating the moving object  100  and the user device  400  through short range communication and a module configured for communicating with the server  300 . For example, the short-range communication may be based on various communication schemes like infrared communication, NFC, WiFi, Bluetooth, beacon or dedicated short range communication (DSRC). When the moving object  100  approaches a predetermined distance range of the wireless charging device  200  or approaches a charging zone as a charging space, the wireless charging device  200  may exchange data with at least one of the moving object  100  and the user device  400  through short range communication. 
     Communication with the server  300  may be performed through the short-range communication or a cellular communication scheme. The server  300  may be a management server for managing the wireless charging device  200  or be a moving object support server for receiving various pieces of state information of the moving object  100  and controlling and managing the moving object  100 . In the present disclosure, the server  300  may receive data associated with information on a charging situation from the moving object  100 , process the information on the charging situation based on the data and provide the information to the user device  400 . 
     The user device  400  is an electronic device different from the electric moving object  100  and may be a mobile device, for example, like a smartphone and a tablet PC. To receive information on a charging situation, the user device  400  may obtain an application providing charging-related information from the server  300  and have the application embedded in it. 
       FIG.  2    is a block diagram showing component modules of an electric moving object according to an exemplary embodiment of the present disclosure. 
     The electric moving object  100  may have the battery  102 , which supplies power to overall driving and electric devices of the moving object  100 , a charging controller  104 , which controls and manages a wired or wireless charging operation of the battery  102 , the power reception module unit  106 , which receives energy through wireless pairing with the power transmission module unit  210 , and a wired charging unit  108  which is connected to a wired charger during a wired charging operation. 
     The charging controller  104  is configured for converting a form or value of supplied power and a function of charging-related control and may generate information on a charging situation, which includes charging progress information and charging obstacle information occurring in abnormality of charging, and relevant data. 
     For example, data associated with charging progress information may include charging state information, which includes a charging amount according to a charging operation, a charging efficiency and an expected charging time, and pairing information between the power transmission module unit  210  and the power reception module unit  106 . 
     Charging obstacle information may be information indicating an element that causes temporary stop or charging failure by abnormality of charging. For example, data associated with charging obstacle information may be at least one of pairing misalignment information, pairing abnormality information, power transmission module abnormality information, moving object abnormality information, power abnormality information, and external environment information. 
     Pairing misalignment information may be data showing misalignment based on location information of the power transmission module unit  210  and the power reception module unit  106 . Pairing abnormality information may be data associated with a poor pairing connection between the power transmission module unit  210  and the power reception module unit  106 , even when they are normally aligned with each other. For example, power transmission module abnormality information may be data associated with lowering charging efficiency caused by the presence of an object and an impact on the power transmission module unit  210 . Moving object abnormality information may be an abnormality of a charging system of the electric moving object  100 . Power abnormality information may be data associated with low power supply caused by power degradation of a wireless charging device. External environment information may be data associated with temperatures of the charging zone  240 , weather information (e.g., snow, fine dust, rainfall) at the time of charging, and other various external factors that become obstacles to wireless charging. 
     Meanwhile, for example, in case of wireless charging, the charging controller  104  may have a wireless charge converter unit (WCCU). As an exemplary embodiment of the present disclosure, the charging controller  104  may be a functional module included in a vehicle charging management system (VCMS) or a battery management system (BMS), which executes integrated charging management and control for the battery  102 . As yet another example, the charging controller  104  may be a function included in a vehicle control unit (VCU) which performs overall management and control of the moving object  100 . The charging controller  104  is not limited to the above-described examples and may operate by being integrated with the processor  120 . The power reception module unit  106  may be configured as a pad type which is exposed or embedded on a bottom surface of the moving object  100 . 
     The electric moving object  100  may include an image acquisition unit  100  configured to obtain image information around the moving object, a sensor unit  112  configured to detect various states other than visual information, a display  114 , a transceiver  116  configured to exchange a signal with an external device (e.g., the wireless charging device  200 , the server  300 , the user device  400 ), a memory  118 , and the processor  120 . 
     The image acquisition unit  110  may include front, side and rear cameras  110   a ,  110   b  and  110   c  for obtaining front, rear, left and right side-view images of the moving object  100 . Thus, the image acquisition unit  110  may provide images obtained from each of the cameras  110   a,    110   b  and  110   c  to the processor  120 , and the processor  120  may combine each image and display surround image information on the display  114 . For example, the surround image information may be provided in a form of surround view monitor (SVM) on the display  114 . The sensor unit  112  may include a Global Positioning System (GPS) detector, a velocity detector, an IMU or INS detector, a distance detector, a proximity recognition detector, a temperature/humidity detector, and a detector for measuring various systems or detecting system conditions in the moving object  100 . 
     The processor  120  performs overall control of the electric moving object  100  and may transmit data associated with information on a charging situation during wireless charging to the server  300  so that the data may be displayed on the user device  400 . Furthermore, the processor  120  may be configured to generate information on a charging situation from the data and to display the information on the display  114 . 
     The electric moving object  100  may include an inverter  122 , which converts a particular type of power of the battery  102  into another type and reduces voltage, and first and second wheel motors  124  and  126  configured to drive by receiving power from the inverter  122 . 
       FIG.  3    is a flowchart illustrating a method of guiding a wireless charging situation of an electric moving object according to another exemplary embodiment of the present disclosure. Hereinafter, the description will be presented mainly through an example of providing information on a charging situation, which is derived from a charging operation, to the user device  400  and the display  114  of the moving object  110  via the server  300 . However, the present disclosure is not limited thereto, but as an exemplary embodiment of the present disclosure, information on a charging situation may be provided only to the user device  400  or only to the display  114 . As yet another example, information on a charging situation may be generated in the moving object  100  or the wireless charging device  200  and be provided to at least one of the user device  400  and the display  114 . Unless technically inconsistent, the description below may be applied to the above-described another example actually in the same way. 
     First, the electric moving object  100  may approach a charging zone of the wireless charging device  200  (S 105 ). 
     When the moving object  100  approaches the charging zone, the moving object  100  may enable communication with the wireless charging device  200  by transmitting an access request message through the transceiver  116 . Furthermore, when the server  300  is a server for supporting a moving object, the moving object  100  may transmit location information to the server  300  so that the server  300  may check whether or not the moving object is approaching the wireless charging device  200 . When the server  300  is a management server of a charging device, the moving object  100  may be connected to the server  300  through the wireless charging device  200 . 
     Next, the moving object  100  may transmit information on the moving object to the wireless charging device  200 , and the wireless charging device  200  may transmit information on the charging device to the moving object  100  (S 110 ). 
     Through exchange of identification information and authentication information between the moving object  100  and the wireless charging device  200 , the wireless charging device  200  may identify and authenticate the moving object  100  configured for a charging service. 
     Information on a moving object may include identification information of the moving object, authentication information, a communication setting with the wireless charging device  200 , location information of the power reception module unit  106 , a charging specification, and a residual amount. Herein, for example, the identification information of the moving object may include an ID uniquely assigned to each moving object, a type of the moving object, and an age. When surround image information is displayed on the display  114  or the user device, the location information of the power reception module unit  106  may be converted and set to a location of a corresponding screen to be displayed on a predetermined portion of the moving object  100 , which is virtually shown. For example, the charging specification may be a total battery capacity of the moving object  100 , a state of health (SoH), a permissible value of energy which may be received per unit time, and a state of a charging system. 
     Information on a charging device may include device identification information, authentication information, and device specification information. For example, the device specification information may include a type of the moving object  100  either capable or incapable of a charging service, location information of the power transmission module unit  210 , suppliable charging power, and state information of the power transmission module unit  210 . The location information of the power transmission module unit  210  may be location data within a charging zone. For example, when the moving object  100  enters the charging zone and a screen of the display  114  or the user device  400  is enabled, the wireless charging device  200  may transmit the location information of the power transmission module unit  210  to the moving object  100  so that the location information of the power transmission module unit  210  may be matched with the location information of the power reception module unit  106  and be displayed on the screen. Each piece of the location information is set based on the charging zone, the location information of the power transmission module unit  210  may be converted to a screen location, which is similar to the power reception module unit  106 , to be displayed on the screen. The state information of the power transmission module unit  210  corresponds to various types of state data of the power transmission module unit  210  affecting an energy transmission operation and may be data of a situation in which such external factors as a neighboring object, a weather condition and particulate matters are affecting the power transmission module unit  210 . 
     Next, the moving object  100  may provide not only the location information of the power transmission module unit  210  and the power reception module unit  106  but also alignment information based on the location information through the display  114  and also provide surrounding information of the moving object  100  in an image form (S 115 ). 
     The moving object  100  may receive the location information of the power transmission module unit  210  from the wireless charging device  200 , and as illustrated in  FIG.  4 A  and  FIG.  4 B , may obtain surround image data including the charging zone  240 , which the moving object  100  enters, and the power transmission module unit  210 .  FIG.  4 A  and  FIG.  4 B  are views exemplarily illustrating images displaying an alignment state along with location information between a power reception module unit of an electric moving object and a power transmission module unit of a wireless charging device. In addition to this, the processor  120  of the moving object  100  may be configured to synthesize image data, which virtually represent the entering moving object  100 , with the surrounding image data and to display image information thus synthesized on the display  114 , as shown in  FIG.  4 A  and  FIG.  4 B . Virtual image data may be processed to represent location information of the power reception module unit  106 . In the above example, alignment information is shown on the display  114  of the moving object  100  but is not limited thereto and may be shown on the user device  400 . 
     In  FIG.  4 A  and  FIG.  4 B , it is illustrated that alignment information with the power transmission module unit  210  is provided as an image according to the power reception module unit  106  which is placed at different locations according to the moving object  100 . The moving object  100  may store location information  210   a  and  210   b  of each power reception module unit  106 . When the moving object  100  approaches the wireless charging device  200 , the processor  120  may obtain an image associated with the charging zone  240  and the location information of the power transmission module unit  210  and may generate alignment information matching unique location information of the power reception module unit  106 . 
     Though not shown in  FIG.  4 A  and  FIG.  4 B , the moving object  100  analyzes the alignment information, and when both module units  106 ,  210   a  and  210   b  are aligned within a range satisfying predetermined charging efficiency, the processor  120  may forward an alignment state configured for charging to the display  114  or the user display  400 . 
     Next, the moving object  100  or the user device  400  may receive a command associated with the start of charging from a user and transmit the command to the wireless charging device  200  so that the wireless charging device  200  may start a charging operation (S 120 ). 
     The user may input a request message including at least one of a target charging amount and an expected charging time through at least one of the moving object  100  and the user device  400 , and the wireless charging device  200  may start charging according to the request message. The request message may include a request for information on a charging situation, which is provided to the user device  400 , and may be transmitted to the wireless charging device  200  via the server  300 . In the instant case, when receiving the request message, the server  300  may request the processor of the moving object  100  to transmit data associated with the information on the charging situation and may receive and accumulate the data to monitor and manage a charging operation. Furthermore, the wireless charging device  200  may determine, according to a charging specification of the moving object  100 , whether or not the user&#39;s request is satisfied and may perform a charging operation which is determined according to a result of determination. 
     Next, the server  300  may provide charging progress information to the user device  400  (S 125 ). 
     Step S 125  will be described with reference to  FIG.  5 A  and  FIG.  5 B .  FIG.  5 A  and  FIG.  5 B  are flowcharts showing a process of providing charging progress information. 
     As described at step S 120 , the user device  400  may request information on a charging situation to the server  300 . Information on a charging situation may include charging state information according to a charging operation, charging progress information including pairing information, and charging obstacle information that occurs due to charging abnormality. When no charging abnormality occurs during a charging operation, the information on a charging situation may include charging progress information. During normal charging, the information on a charging situation requested by the user device  400  may be actually charging progress information. 
     The server  300  may receive a request message of charging progress information and transmit the request message to the processor  120  of the moving object  100 . When receiving the message, the processor  120  may request information on a charging situation to the charging controller  104  and request a pairing state and a surround view image during a charging operation to the image acquisition unit  110 . 
     The charging controller  104  may monitor the intensity and state of energy, which is supplied from the power transmission module unit  210  to the power reception module unit  106 , in real time and determine a cumulative charging amount, an expected residual charging time, and charging efficiency. Furthermore, the charging controller  104  may monitor a pairing state between both module units in real time according to a communication condition, an external object and weather. Accordingly, the charging controller  104  may generate data associated with charging state information by checking a charging state and a pairing state. 
     The charging controller  104  may obtain a surround image and a change of alignment state between both module units according to a movement of the moving object  100  during a charging operation in real time from the image acquisition unit  110 . The surround image may be generated to detect an external object affecting the charging operation. The charging controller  104  may process image information to include all the surround image and alignment states. 
     The charging controller  104  may transmit data associated with charging state information and image information to the processor  120 , and the processor  120  may be configured to transmit data associated with charging progress information including the data and the image information to the server  300 . Herein, the data associated with the charging progress information may be transmitted as the above-described data and information as they are, or may be transmitted as charging progress information which is generated or processed based on the data. 
     The server  300  may receive the data associated with charging progress information and generate or process the data as charging progress information. The server  300  may transmit the charging progress information to the user device  400  in real time and provide the information as illustrated in  FIG.  6   .  FIG.  6    is a view exemplarily illustrating an image displaying charging progress information. Referring to  FIG.  6   , for example, charging progress information may include charging state information which provides whether or not a charging operation is in progress and whether or not the charging operation is normal, a current charging amount relative to a target charging amount, and an expected residual time to the target charging amount on a user-friendly interface. Furthermore, the charging progress information may be image information which is provided in a form of surround view in real time, and the image information may include surround image information and alignment state information between both module units. For example, the alignment state information may be generated as an alignment image of location information between the power transmission module unit  210  and the power reception module unit  106  within the charging zone  240 . The surround image information may be an omnidirectional image encompassing the moving object  100  and the charging zone  240  so that influential factors of a charging operation like an external object and a weather condition may be checked in real time. 
     Referring to  FIG.  3    again, the moving object  100  may check whether or not a charging abnormality occurs during a charging operation (S 130 ), and when the abnormality exists (Y of S 130 ), at least one of the moving object  100  and the wireless charging device  200  may stop charging (S 135 ). Next, the moving object  100  may search for a charging obstacle element that causes the stop of charging (S 140 ). 
     Step S 130  to step S 140  will be described with reference to  FIG.  7 A  and  FIG.  7 B .  FIG.  7 A  and  FIG.  7 B  are flowcharts showing a process of providing charging obstacle information. 
     When receiving data associated with charging progress information during a charging operation, the charging controller  104  of the moving object  100  may monitor data associated with progress information like the intensity of energy supplied to the power reception module unit  106 , an energy state, a pairing state and charging efficiency. When, as a monitoring result, at least one of the energy intensity, the energy state, the pairing state and the charging efficiency is equal to or less than a threshold or is a specific energy state, the charging controller  104  or the wireless charging device  200  may stop wireless charging. 
     Subsequently, the charging controller  104  may analyze data associated with progress information causing the stop of charging and obtain charging state information associated with the stop. The charging controller  104  may search for an element, which actually causes the stop of charging, among obstacle elements based on the data associated with the progress information. An obstacle element may be an external environment including temperatures, weather situations and the like, which cause a pairing misalignment between both module units  106  and  210 , pairing abnormality information caused by poor pairing connection during energy transmission, a transmission module abnormality, a charging system abnormality of the moving object  100 , degradation of power supplied from the wireless charging device  200 , and significant degradation of charging efficiency. 
     Pairing misalignment may occur as early as before the start of charging or may occur as the moving object  100  moves during a charging operation after being correctly aligned. Pairing misalignment may be recognized as a change of alignment state between both module units, which is estimated from the image acquisition unit  110 . Data associated with the power transmission module abnormality may be obtained through a detector of the wireless charging device  200 , the image acquisition unit  110  of the moving object  100 , and the sensor unit  112 . The presence of an object and an impact on the power transmission module unit  210  may be recognized through detected data of the detector and the sensor unit  112 , which are detected during the degradation of charging efficiency, and a surround image which is obtained from the image acquisition unit  110  at the time of the degradation. The external environment may be checked based on weather data which are transmitted from a temperature-humidity detector of the sensor unit  112  and the server  300 . 
     Next, the charging controller  104  may collect charging state information associated with stop and transmit the information to the processor  120 . Furthermore, when image information, in which pairing misalignment and power transmission module abnormality may be identified, is included in the information associated with stop, the charging controller  104  may request and obtain a surround view type of image information at the time of stop of charging from the image acquisition unit  110 . The charging controller  104  may receive image information and transmit the image information together with charging state information associated with stop to the processor  120 . 
     Referring to  FIG.  3    again, the processor  120  may transmit the stop-related information and the image information to the server  300 , and the server  300  may generate or process charging obstacle information based on the information and provide the charging obstacle information to the user device  400  (S 145 ). In the instant case, the processor  120  may generate charging obstacle information based on the stop-related information and the image information and provide the charging obstacle information in a similar form to the user device to the display  114 . 
     Next, at least one of the user, the moving object  100  and the wireless charging device  200  may try a measure to dissolve an obstacle element by referring to the charging obstacle information, and based on the measure, at least one of the moving object  100  and the wireless charging device  200  may determine whether or not a charging resumption state is reached. That is, it may be determined whether or not the obstacle element according to the measure is dissolved (S 150 ). 
     When the measure is not implemented or an implemented measure is not sufficient to dissolve the obstacle element, at least one of the moving object  100  and the wireless charging device  200  may finally stop wireless charging, and the server  300  may receive a final stop message from the moving object  100  and transmit failure information to the user device  400  (S 155 ). The server  300  may include charging obstacle information causing the failure among the pre-stored pieces of information in the failure information and transmit the information to the user device  400 . In the instant case, the server  300  or the processor  120  may provide the failure information through the display  114 . 
     On the other hand, when it is determined that the measure dissolves the obstacle element, at least one of the moving object  100  and the wireless charging device  200  may resume wireless charging, and the processor  120  may provide not only charging resumption information but also charging progress information due to resumption to the server  300  and the display  114 . The server  300  may process the information to be transmitted to the user device. 
     Step S 145  to step S 160  will be described with reference to  FIG.  7 A  and  FIG.  7 B . 
     The processor  120  may receive and transmit stop-related charging state information and/or image information to the server  300 . Next, the server  300  may generate or process charging obstacle information based on the information and transmit the charging obstacle information to the user device  400 . As illustrated in  FIG.  8 A ,  FIG.  8 B ,  FIG.  8 C ,  FIG.  8 D , and  FIG.  8 E , the user device  400  may show the charging obstacle information to a user according to a type of an obstacle element. The charging obstacle information may also be provided to the display  114  in a similar to  FIG.  8 A ,  FIG.  8 B ,  FIG.  8 C ,  FIG.  8 D , and  FIG.  8 E . 
       FIG.  8 A ,  FIG.  8 B ,  FIG.  8 C ,  FIG.  8 D , and  FIG.  8 E  are views exemplarily illustrating images displaying charging obstacle information. 
       FIG.  8 A  shows temporary stop of charging corresponding to a case in which charging obstacle information is a pairing misalignment between both module units  106  and  210 . The charging obstacle information may not only present a charging amount before the stop of charging and an expected residual charging time but also mark a current suspended state of charging as ‘stop’. In the present drawing, the suspended state is marked in a different color from the color of normal or poor charging but is not limited thereto. The suspended state may be provided by various interface forms which enable users to perceive stop of charging. A poor state may be presented when charging is not suspended but performed with low efficiency. Though not shown in  FIG.  8 A ,  FIG.  8 B ,  FIG.  8 C ,  FIG.  8 D , and  FIG.  8 E , by the moving object  100  and the server  300 , information on poor charging, which indicates an obstacle element causing a poor state, may be provided to the user device  400 . 
     For the user&#39;s intuitive understanding, as in  FIG.  8 A , obstacle information associated with pairing misalignment may be indicated by a misalignment state image and a surround image based on the location information of both module units  106  and  210  in a surround view mode. Furthermore, charging obstacle information may provide guide information for dissolving pairing misalignment as well as pairing misalignment information. In the case of  FIG.  8 A , to dissolve a stopping element (or obstacle element) like pairing misalignment, guide information may provide a ‘pad alignment state check request’ message and a current alignment state between both module units  106  and  210 . By referring to the guide information, the user may take a necessary measure for pairing alignment configured for charging. 
       FIG.  8 B  shows temporary stop of charging corresponding to a case in which charging obstacle information is a pairing abnormality caused by a poor pairing connection between both module units  106  and  210 . The charging obstacle information may present ‘stop’ of operation state, a current charging amount, an expected residual charging time, and a pairing abnormality state caused by a poor connection. To dissolve an obstacle element like a pairing abnormality, guide information may be provided in a form of message that the moving object  100  is trying a normal pairing connection again and the user may stand by until the normal pairing connection is completed. 
       FIG.  8 C  shows stop of charging corresponding to a case in which charging obstacle information is an abnormality of the moving object  100  caused by a charging system abnormality of the moving object  100 . The charging obstacle information may present ‘stop’ of operation state, a current charging amount, an expected residual charging time, and an abnormal state of the moving object. Besides, guide information may recommend the maintenance of the moving object to dissolve an obstacle element like an abnormality of the moving object. 
       FIG.  8 D  shows stop of charging corresponding to a case in which charging obstacle information is an abnormality of power caused by power degradation of the wireless charging device  200 . The charging obstacle information may present ‘stop’ of operation state, a current charging amount, an expected residual charging time, and an abnormal state of power supply. 
       FIG.  8 E  shows temporary stop of charging corresponding to a case in which charging obstacle information is an abnormality of a power transmission module indicating an abnormal state of the power transmission module unit  210 . The charging obstacle information may present, for example, ‘stop’ of operation state, a current charging amount, an expected residual charging time, and the presence of an external object on the power transmission module unit  210 . For example, the external object, which is a moving object, may be an object which is moved by an external force or external control. For the user&#39;s intuitive understanding, obstacle information associated with the presence of an object may be marked as a virtual image in which another object exists between both module units  106  and  210 . To dissolve an obstacle element like the presence of an object, guide information may provide a message about the presence of obstacle, and the user may take a measure to remove the obstacle by referring to the guide information. 
     Referring to  FIG.  7    again, the processor  120  may determine whether or not the resumption state of charging is reached by determining whether or not an obstacle element is dissolved d according to the guide information exemplified in  FIG.  8 A ,  FIG.  8 B ,  FIG.  8 C ,  FIG.  8 D , and  FIG.  8 E . 
     When the measure is not implemented at all or when a measure thus implemented is not sufficient, the processor  120  may finally stop wireless charging, and the server  300  may receive a final stop message and transmit failure information to the user device  400 . In the example of  FIG.  8 B , when the moving object  100  tries a normal pairing connection repeatedly but no normal pairing is achieved within a predetermined time or a predetermined number of times, the processor  120  may determine that the resumption state of charging cannot be reached. The processor  120  may request final stop of charging through the charging controller  104  and transmit a final stop message to the server  300 . Based on the message, the server  300  may change the operation state from temporary stop to final stop of charging and generate failure information accordingly. The server  300  may transmit the failure information to the user device  400 . In the example of  FIG.  8 B , failure information may indicate that charging obstacle information causing charging failure is a poor pairing connection and the charging service is not provided due to the poor pairing connection. Accordingly, the temporary stop screen of the  FIG.  8 B  may be modified to indicate that the charging operation fails and the charging obstacle information is poor pairing. 
     In the above example, guide information includes an appropriate measure and thus checks whether or not the measure is completely implemented and transmits failure information. As an exemplary embodiment of the present disclosure, guide information may not provide a measure to remove an obstacle element in a short time. Like in  FIG.  8 C  and  FIG.  8 D , when charging obstacle information is information on an abnormality of a moving object or information on a power abnormality, the processor  120  may be configured to skip a checking process for removing an obstacle element, to finally stop charging and to transmit a final stop message to the server  300 . Thus, the server  300  may transmit not charging obstacle information according to temporary stop but failure information to the user device  400 . The temporary stop screens of  FIG.  8 C  and  FIG.  8 D  may be modified to indicate that the charging operation fails and the charging obstacle information is an abnormality of moving object and a very low level of external power supply. 
     On the other hand, when it is determined that the measure dissolves the obstacle element, the moving object  100  may resume wireless charging, the processor may provide not only charging resumption information but also charging progress information due to resumption to the user device  400  via the server  300 . 
     Referring to  FIG.  3    again, when it is confirmed by the moving object  100  that no abnormality of charging occurs (N of S 130 ), the moving object  100  may determine whether or not wireless charging is completed in accordance with the user&#39;s charging request (S 165 ). When it is determined that the charging is completed, the moving object  100  may transmit data associated with charging completion information via the server  300  (S 170 ). At the instant time, the moving object  100  may transmit the data to the display  114 . 
     Step S 170  will be described with reference to  FIG.  9 A  and  FIG.  9 B .  FIG.  9 A  and  FIG.  9 B  are flowcharts showing a process of providing charging completion information. 
     When charging is completed, the charging controller  104  may generate information on a charging completion state. The information on a charging completion state may include a target charging amount, a completed charging amount, an available travel distance and the like. Furthermore, the charging controller  104  may request image information including a pairing state between both module units at the time of charging completion and a surround image in a form of surround view. Under the control of the processor  120 , the charging controller  104  may transmit data associated with charging completion information including information on a charging completion state and image information to the server  300 . Herein, the data associated with the charging completion information may be transmitted as the above-described state and information as they are, or may be transmitted as charging completion information which is generated or processed based on the data. 
     The server  300  may receive the data associated with charging completion information and process the data as charging completion information. The server  300  may transmit the charging completion information to the user device  400 , and the user device  400  may provide the charging completion information as exemplified in  FIG.  10   .  FIG.  10    is a view exemplarily illustrating an image displaying charging completion information. Referring to  FIG.  10   , for example, charging completion information may provide completion of a charging operation, a target charging amount, a completed charging amount, an available travel distance and the like to a user-friendly interface. In  FIG.  10   , an expected residual charging time is exemplified as 0, but a required charging time may be provided. Furthermore, image information may include surround image information and alignment state information between both module units. 
       FIG.  11    is a flowchart showing a process of guiding a charging location of a moving object according to a neighboring object. 
       FIG.  11    relates an exemplary embodiment where an optimal charging location is guided in case a constraint on alignment between both module units  106  and  210  exists due to a neighboring object while the moving object  100  enters the charging zone  240 . 
     First, like in step S 115  of  FIG.  3   , the moving object  100  may provide not only the location information of the power transmission module unit  210  and the power reception module unit  106  but also alignment information based on the location information through the display  114  and also provide surrounding information of the moving object  100  in an image form (S 205 ). 
     Next, at least one of the image acquisition unit  110  and the sensor unit  112  may detect a neighboring object around the charging zone  240  and determine whether or not a distance to the neighboring object (which is exemplified as another moving object around the charging zone  240  in  FIG.  12 A ) is equal to or less than a threshold (S 210 ). 
     Distance measurement through the image acquisition unit  110  may estimate a distance between a neighboring object and the moving object  100  through an image analysis according to machine learning for the neighboring object, which is obtained from a surround image, and the moving object  100 . As an exemplary embodiment of the present disclosure, a distance detector and a proximity recognition detector, which are mounted in the sensor unit  112 , may measure a distance to a neighboring object. As yet another example, a distance may be estimated by a combination of the above-described examples. 
     As a result of determination, when a separation distance between the moving object  100  and a neighboring object is equal to or less than a threshold, the processor  120  may maintain a predetermined distance between the charging zone  240  and the neighboring object and generate information on a charging location that realizes normal pairing between the power transmission module unit  210  and the power reception module unit  106 . 
     The processor  120  may check location information of the power reception module unit  106 , and based on charging specification information of the moving object  100  and specification information of the wireless charging device  200 , may also check an overlapping region between the power transmission and reception module units  210  and  106  configured for normal pairing. When there is an overlapping region, as shown in  FIG.  12 A , the processor  120  may process image information so that a virtual charging park line corresponding to the overlapping region may be generated in image information including the location information of both the module units  106  and  210  and a surround image.  FIG.  12 A  and  FIG.  12 B  are views exemplarily illustrating images displaying charging location information of a moving object. The processor  120  may transmit image information to at least one of the display  114  and the user device  400 . 
     Next, while checking the charging park line represented as an image, a user may move the moving object  100  to the charging zone  240 , as shown in  FIG.  12 B . Based on mobile image information of the moving object  100 , which is obtained in real time, the processor  100  check the alignment state of the power reception module unit  106  relative to the power transmission module unit  210 , and when a location alignment configured for charging is achieved, may give a location alignment message to the user (S 220 ). 
     Next, the user may confirm the location alignment message thus notified and transmit a command associated with start of charging to the moving object  100  or the user device  400  (S 225 ). The command is transmitted to the wireless charging device  200 , and the wireless charging device  200  may start a charging operation.
