Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and relates to a charging technology for new energy vehicles, and in particular to a method and system for mobile positioning of a charging package. Background Art

[0002] With the continuous development of science and technology and the improvement of people's living standards, the number of cars has increased dramatically. Along with the sharp increase in fuel-powered cars, the environmental pollution caused by the burning of fossil fuels has become increasingly prominent. With the non-renewable and decreasing fossil fuels and the environmental pollution caused by fuel-powered cars, new energy vehicles, especially electric vehicles, that is, electric-driven vehicles, use electricity instead of fuel, which are green, energy-saving and have low electricity costs, and are therefore widely favored.

[0003] Electric vehicles, as the name implies, are vehicles that are mainly powered by electricity. Most vehicles are directly driven by electric motors. Some vehicles install the electric motors in the engine compartment, and some vehicles directly use wheels as rotors for four electric motors. Electric vehicles need to be equipped with batteries, which are charged by charging, and then the batteries provide power when the vehicle is driving. Charging electric vehicles is usually completed by charging piles.

[0004] The function of the charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0005] In the prior art, more and more charging piles will adopt a mobile charging structure, that is, the gun box (charging pack) can be moved on the charging pile. During the movement of the gun box (charging pack), it is necessary to control and accurately park the gun box (charging pack) in the corresponding parking space. The invention patent with application number 201811496591.0 discloses a mobile charging pile control system and method, and a mobile charging pile. Car owners who need to park and charge can communicate with the control terminal through an application on a mobile terminal (such as a mobile phone). The car owner sends a parking charging request to the control terminal through the application on the mobile terminal. The control terminal will allocate a charging parking space according to the parking charging request, and the control terminal will send the location information of the allocated charging parking space to the mobile terminal. At the same time, the control terminal will determine whether there is a mobile charging pile at the charging parking space. When there is a mobile charging pile at the parking space, the system does not need to call the mobile charging pile. When there is no mobile charging pile at the location of the charging parking space, it is necessary to call the mobile charging pile, record the charging parking space as the target parking space, and then query the idle mobile charging piles around, send a movement instruction to the idle mobile charging pile, and then the mobile charging pile moves to the target parking space according to the movement instruction. When there is no idle mobile charging pile in the system, it is optional to return to the query again, or wait for further processing results of the control terminal.

[0006] In addition, the invention patent with application number 202210314850.3 also discloses a mobile new energy intelligent charging pile for parking lots and its control method. When the user scans the parking QR code at the parking space, the chassis processes the received information and allocates the vacant charging piles nearby. The operation of the first motor drives the active wheel to roll along the top of the I-beam bracket. During the movement of the charging pile body, the position reader scans the position barcode to determine the position of the charging pile body; while the charging pile body moves, the reset spring pushes the sliding contact to always contact the surface of the wire, and the sliding contact slides along the surface of the wire to provide power for the charging pile body. When the charging pile body moves to the corresponding parking space, the chassis controls the second motor to drive the take-up reel to rotate and put down the charging cable for the car to charge. After use, the second motor runs in reverse to rewind the charging cable around the surface of the take-up reel.

[0007] Based on the above-mentioned prior art, the existing charging piles still have technical defects: the invention patent application 201811496591.0 allocates charging parking spaces after initiating a charging request, and the driver then drives to find the allocated charging parking spaces. The process is relatively cumbersome and the charging efficiency is low. As for the invention patent application 202210314850.3, the gun box (charging pack) moves on the power rail while scanning the code on the power rail, and stops moving after scanning the correct code. Since the moving gun box (charging pack) needs to scan the code, the movement speed of the gun box (charging pack) must be slow, and the slow movement speed will directly lead to a long charging waiting time and low efficiency; and when scanning the code, the gun box (charging pack) is usually in a stopped state, and a long reaction time is required after scanning the code, so the charging waiting time is long and the efficiency is low. Summary of the invention

[0008] The purpose of the present invention is to solve the technical problems in the prior art that the gun box (charging pack) has a slow moving speed and low charging efficiency when scanning a code while moving, and to provide a mobile charging system and a charging method.

[0022] Step S23, the charging pack is on the power rail. During the movement, the charging pack continuously scans the induction switch on the power rail. When the N+1th induction switch is sensed, the charging pack stops moving.

[0023] A charging pack mobile positioning system includes a power rail and a charging pack. A charging mark is set at the position corresponding to each parking space on the power rail, and a charging request is initiated through the charging mark.

[0024] An information association module is used to associate and store the location information of each parking space and the charging identifier corresponding to each parking space;

[0025] The control system is used to control the charging pack to move on the power rail and stop at the position associated with the charging identifier on the power rail according to the charging request initiated by the charging identifier and the stored association information between the charging identifier and the parking space.

When a charging request is initiated through the charging logo, the control system obtains the parking space information corresponding to the charging logo according to the stored association information, and then the control system controls the charging pack to move on the power rail, and controls the charging pack to stop at the corresponding position on the power rail, and then the control device controls the charging pack to extend the rolled charging cable, and plugs the charging gun at the end of the charging cable into the charging interface of the electric vehicle; when the charging pack moves on the power rail, since the target parking space information is obtained in advance, during the entire movement process of the charging pack, the movement will not stop or reduce the movement speed due to sensing and identifying other parking spaces. The movement speed of the charging pack is significantly improved, thereby effectively solving the problem of low charging efficiency caused by the slow movement speed of the charging pack due to scanning codes, etc., greatly shortening the waiting time when the charging pack moves during the charging process, and improving the efficiency of the entire charging process as a whole.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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 described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] The present embodiment provides a method for moving and positioning a charging pack, which includes a mobile charging pile, and the charging pile includes a power rail 2, and the power rail 2 can be fixedly connected to a carrier such as a wall, ceiling or ground column of a parking lot. A charging pack 1 is installed on the power rail 2, and the charging pack 1 can be moved on the power rail 2; of course, one charging pack 1 on the power rail 2 can be provided, or two, three or more charging packs 1 can be provided, so that by moving the charging pack 1, electric vehicles parked in parking spaces at different positions under the power rail 2 can be charged. One end of the power rail is connected to the external power grid through a cable, and the power rail 2 is electrically connected to the charging pack 1, and the electric energy of the external power grid is transmitted to the charging pack through the power rail 2.

[0050] The charging bag 1 is provided with a winding structure, on which a charging cable is wound, and a charging gun is connected to the end of the charging cable. When charging is needed, the winding structure inside the charging bag rotates, the charging cable is output from the charging bag, and then the charging gun is inserted into the charging port of the electric vehicle for charging; when charging is completed, the charging gun is unplugged from the electric vehicle, and then the winding structure of the charging bag 1 rotates to rewind the charging cable (and the charging gun) into the charging bag.

[0051] In addition, in order to more accurately and efficiently move the charging pack to the designated parking space, it is also necessary to set a charging mark 2 at the position corresponding to each parking space on the power rail 2, and associate the charging mark 2 with the corresponding parking space, and store the associated information, so that the charging mark 2 can be used to directly obtain the parking space above which the charging pack should be parked during subsequent positioning. The charging mark 5 can be a QR code, an IC card reader, or an RFID reader, etc. When a terminal (such as a mobile phone) is used to scan the QR code, the IC card is placed in the reading area of ​​the IC card reader and the IC card information is read, or the RFID card is placed in the reader of the RFID reader and the RFID card information is read, the charging demand is initiated to the control system, and the control system executes the processing of turning on the associated induction switch, the charging pack moves on the power rail 2, the inductor on the charging pack 4 is started and the induction switch on the power rail 2 is sensed. In addition, the charging mark 5 can even be a button / key corresponding to each parking space on the control display terminal on one side of the charging device. When someone presses a button / key, the charging demand is initiated to the control system.

[0052] A control system is also configured, which is connected to the charging pack 1, the charging identifier 5 and other signals, and is used to control the charging pack 1 to move on the power rail according to the charging request initiated by the charging identifier 5, and stop at the position associated with the charging identifier 5 on the power rail 2. Figure 1 The control and display terminal shown in the figure can be used as the control system of the entire mobile charging system, and can also be used as the control subsystem corresponding to the power rail 2.

[0053] The specific positioning steps are as follows:

[0054] Step S1, a charging mark 5 is set at the position corresponding to each parking space on the power rail 2, and the position information of each parking space and the charging mark 5 corresponding to each parking space are associated and stored;

[0055] Step S2, initiating a charging request through the charging identifier, the control system controls the charging pack 1 to move on the power rail according to the charging request initiated by the charging identifier 5 and the stored association information between the charging identifier and the parking space, and stops at the position associated with the charging identifier 5 on the power rail.

[0056] Preferably, in step S2, the control steps of controlling the charging pack 1 to move and stop on the power rail are:

[0057] Step S21, the control system determines the charging identifier Ai in use according to the charging request (i=1, 2, ..., n, n is a natural number), and determines the information of the parking space Bi to be parked corresponding to the charging identifier Ai in use according to the associated information stored in step S1;

[0058] Step S22, based on the information of the starting parking space B1 of the charging pack at the starting position or the information of the charging parking space B' at the last charging, combined with the information of the parking space Bi to be parked finally determined in step S21, calculate the number of parking spaces N between the parking space Bi to be parked and the starting parking space B1 or the charging parking space B' at the last charging;

[0059] Step S23, according to the number of parking spaces N calculated in step S22, combined with the time t required for the charging package to move one parking space, the moving time T required for the charging package is obtained, T = (N+1)t;

[0060] Step S24, the charging pack stops moving after moving on the power rail for a period of time T.

[0061] Example 2

[0062] This embodiment is based on the first embodiment. In addition to setting a charging mark at the position corresponding to each parking space on the power rail, an induction switch is also set at the position corresponding to each parking space on the power rail, and the position information of each parking space, the charging mark corresponding to each parking space and the induction switch are associated and stored;

[0063] In step S2, the control steps of the control system controlling the charging pack to move and stop on the power rail are:

[0064] Step S21, the control system determines the charging identifier Ai in use according to the charging request (i=1, 2, ..., n, where n is a natural number), and determines the information of the parking space Bi to be parked corresponding to the charging identifier Ai in use, and the induction switch Ci corresponding to the parking space Bi to be parked according to the associated information stored in step S1;

[0065] Step S22, based on the information of the starting parking space B1 of the charging pack at the starting position or the information of the charging parking space B' at the last charging, combined with the information of the parking space Bi to be parked finally determined in step S21, calculate the number of parking spaces N between the parking space Bi to be parked and the starting parking space B1 or the charging parking space B' at the last charging;

[0066] Step S23, the charging pack is on the power rail. During the movement, the charging pack continuously scans the induction switch on the power rail. When the N+1th induction switch is sensed, the charging pack stops moving.

[0067] Example 3

[0068] In theory, the charging pack in this application needs to realize the winding of the charging cable, and the existing winding structure can be used, or the winding structure inside the charging pack can be innovatively designed.

[0069] This embodiment is based on Embodiment 1 and Embodiment 2. In order to fully disclose the winding structure inside the charging pack, this embodiment provides a specific structure of a charging pack 1 and requests protection of the specific structure of the charging pack in other patent applications.

[0070] The charging pack 1 includes:

[0071] The shell 11 is mainly the outer shell of the charging pack 1, which is formed by buckling the left shell 11 and the right shell 11, and forms a cavity in the cavity inside the shell 11. The cavity in the shell 11 includes a cavity for placing the take-up frame 13 and a cavity for placing the charging gun 17.

[0072] The charging cable 14 is used to transmit electric energy. One end of the charging cable 14 passes through the shell 11 and is connected to the power rail 2 after passing through the mobile body 4 and is turned on (the so-called conduction means that the circuit is connected and electric energy can be transmitted), and the electric energy received by the conductive column 41 is transmitted to the charging cable 14; the other end of the charging cable 14 is connected to the charging gun 17, and the electric energy transmitted from the conductive column 41 is transmitted to the battery of the electric vehicle.

[0073] The wire take-up frame 13 is mainly used for winding and accommodating electric wires. The wire take-up frame 13 is installed in a cavity of the housing 11 for placing the wire take-up frame 13 , and the wire take-up frame 13 can rotate freely in the housing 11 .

[0074] The wire feeding roller set 15 is installed on the inner wall of the wire inlet side of the housing 11. The charging wire 14 passes through the wire feeding roller set 15 and is wound in the wire take-up frame 13. The wire feeding roller set 15 includes two wire feeding rollers, which are driven by the driving motor of the charging pack 1 through the gear set to rotate synchronously.

[0075] In addition, a guide groove 12 is provided on the feeding side of the housing 11, and the depth of the guide groove 12 gradually decreases in the direction close to the take-up frame 13. Under the action of the guide groove 12, the charging cable 14 is guided to the outer side and outer edge of the take-up frame 13, that is, the charging cable 14 is first wound around the outer side and outer edge of the take-up frame 13, and then gradually wound towards the inner side and inner edge.

[0076] It should be noted that in the present embodiment, the wire feeding roller group 15 is an active part, and the wire taking-up frame 13 is a driven part. The wire feeding roller group 15 drives the charging wire 14 to move into or out of the shell 11. The charging wire 14 with a certain strength is bent in the wire taking-up frame 13 and stretched outward against the inner wall of the wire taking-up frame 13 or the inner wall of the wound wire. In the process of the charging wire 14 being wound inward or outputted outward, the wire taking-up frame 13 will be driven to rotate, thereby facilitating the winding of more charging wires 14 or the output of the wound charging wires 14.

[0077] Preferably, a specific structure of a take-up frame 13 is also provided.

[0078] The take-up frame 13 comprises:

[0079] The center plate 132 is used to be connected to the rotating shaft of the take-up frame 13 and rotates together with the rotating shaft of the take-up frame 13 in the charging pack 1.

[0080] The outer edge frame 133 is an annular structure. The inner diameter of the outer edge frame 133 is larger than the outer diameter of the center plate 132 . The outer edge frame 133 is coaxial with the center plate 132 but not coplanar. The outer edge frame 133 is located between the center plate 132 and the wire feeding roller assembly 15 .

[0081] The end frame 134 is an annular structure. The inner diameter of the end frame 134 is larger than the outer diameter of the center plate 132. The outer diameter of the end frame 134 is smaller than the inner diameter of the outer edge frame 133. The outer edge frame 133 and the center plate 132 are all coaxial but not coplanar. The outer edge frame 133 is located between the center plate 132 and the end frame 134.

[0082] A plurality of connecting frames 135 are provided, and the connecting frames 135 are evenly distributed along the circumference of the center plate 132 and radially distributed outward. One end of each connecting frame 135 is fixedly connected to the center plate 132, and the other end thereof is connected to the outer edge frame 133 and then bypasses the outer edge frame 133 to connect to the end frame 134.

[0083] After the outer edge frame 133, the end frame 134 and the connecting frame 135 are connected as described above, the area enclosed by the center plate 132, the outer edge frame 133, the end frame 134 and the connecting frame 135 constitutes a wire winding storage area 136 for accommodating the charging cable 14, and the area enclosed by the end frame 134 is a winding entrance area 131 for the charging cable 14 to enter the winding frame 13.

[0084] As for the connection between the charging pack and the power rail after adopting the above-mentioned structure, the existing technology can be used, such as the invention patent application with application number 202210314850.3. Figure 3 The structure shown is sufficient.
