[0002] At present, in electric vehicle charging stations, one charging pile is installed for each parking space. This installation solution leads to high initial investment costs for charging stations. At the same time, in actual applications, the utilization rate of charging piles is low and the actual idle rate is high, resulting in a long investment recovery period and failure to make quick profits. Utility Model Content

[0003] In view of the above problems, the present application provides a charging system, which solves the problems of too high idle rate of charging piles and excessive overall economic investment in the charging station design scheme of setting one charging pile for one parking space through charging piles. At the same time, based on the charging piles, the charging needs of vehicles in different parking spaces can be met, the number of installed charging piles can be reduced, and the cost can be reduced. In addition, during the charging process, by controlling one or more of the energy storage device and the power supply to charge the vehicle, different charging power requirements and different charging scenarios can be met, thereby ensuring the charging effect.

[0004] The present application provides a charging system for providing charging services to multiple fixed parking spaces, the system comprising: a charging pile, on which a first power supply input interface and an energy storage device are provided; multiple first power supply interfaces, which are arranged in a one-to-one correspondence with multiple fixed parking spaces; a power supply device, which is connected to the multiple first power supply interfaces and a power supply source, and is configured to output first charging power to the multiple first power supply interfaces based on the power of the power supply source; wherein, when the charging pile moves to the target first power supply interface and the first power supply input interface of the charging pile is connected to the target first power supply interface, or when the first power supply input interface of the charging pile is retracted to the target first power supply interface and connected to the target first power supply interface, the charging pile charges the vehicle in the target parking space corresponding to the target first power supply interface based on the first charging power and / or the second charging power provided by the energy storage device.

[0005] In the technical solution of the present application, multiple first power supply interfaces are set one by one corresponding to multiple fixed parking spaces, and the multiple first power supply interfaces are connected to the power supply through the power supply device. When the vehicle in the target fixed parking space has a charging demand, the owner parks the vehicle in one of the fixed parking spaces. At this time, the charging pile can be moved to the target first power supply interface corresponding to the fixed parking space, or the first power supply output interface of the charging pile can be retracted to the target first power supply interface corresponding to the fixed parking space. The owner connects the first power supply input interface of the charging pile with the target first power supply interface, and the power supply output interface of the charging pile, i.e., the charging gun, is connected to the charging port of the vehicle, thereby executing the charging process of the vehicle. In the process of charging the vehicle, the vehicle can be charged only based on the first charging energy provided by the power supply, or only through the second charging energy provided by the energy storage device in the charging pile, or the vehicle can be charged simultaneously by the first charging energy provided by the power supply and the second charging energy provided by the energy storage device in the charging pile, so as to achieve high-power charging. The specific control strategy can be set based on the actual situation and the charging power demand. This technical solution solves the problems of high idle rate of charging piles and excessive overall economic investment in the charging station design of setting up one charging pile for one parking space through charging piles. At the same time, the charging piles can meet the charging needs of vehicles in different parking spaces, reduce the number of charging piles installed, and reduce costs. In addition, during the charging process, by controlling one or more of the energy storage device and the power supply to charge the vehicle, different charging power requirements and application scenarios can be met, ensuring the charging effect.

[0006] In some embodiments, the charging pile is further provided with a second power supply input interface, and the charging system further comprises a plurality of second power supply interfaces, and the plurality of second power supply interfaces are arranged one-to-one with the plurality of first power supply interfaces, and the power supply device is also connected to the plurality of second power supply interfaces, and outputs a third charging power to the plurality of second power supply interfaces based on the power of the power supply; wherein, when the charging pile moves to the target second power supply interface and the second power supply input interface of the charging pile is connected to the target second power supply interface, or the second power supply input interface of the charging pile is retracted to the target second power supply interface and connected to the target second power supply interface, the charging pile also charges the energy storage device based on the third charging power; wherein, the target second power supply interface corresponds to the target first power supply interface.

[0007] When the charging pile moves to the target first power supply interface, the target second power supply interface, or the charging pile does not move, and only the first power supply input interface of the charging pile is extended to the target first power supply interface, and the second power supply input interface is extended to the target second power supply interface, the first power supply input interface of the charging pile is connected to the target first power supply interface, the second power supply interface is connected to the target second power supply interface, and the charging output interface is connected to the charging port of the vehicle. In the process of charging the vehicle, when the output power of the power supply can meet the power demand of the vehicle, the vehicle is charged by the first charging power provided by the power supply. At this time, if the stored power in the energy storage device is lower than the preset power threshold, the energy storage device is charged by the third charging power provided by the power supply. In this way, the energy storage device can be automatically recharged by the power supply to ensure that the power in the energy storage device is sufficient, which provides a guarantee for the charging effect. At the same time, there is no need to manually recharge the energy storage device, which reduces labor costs and makes the charging process more convenient.

[0008] In some embodiments, the power supply device includes: a first power conversion unit, one end of which is connected to an AC power grid; a second power conversion unit, one end of which is connected to the other end of the first power conversion unit, and the other end of the second power conversion unit is connected to the multiple first power supply interfaces and the multiple second power supply interfaces; wherein the first charging power and the third charging power are output based on the power of the AC power grid through the first power conversion unit and the second power conversion unit.

[0009] The AC power provided by the AC power grid is converted into DC power through the first power conversion unit, and the DC power is converted into voltage through the second power conversion unit to output the first charging power and the third charging power of the target voltage, wherein the voltage of the first charging power and the third charging power can be the same or different, and can be applied based on actual conditions. In this way, the power of the AC power grid is converted into the first charging power and the third charging power by the first power conversion unit and the second power conversion unit to meet the charging needs in different scenarios and ensure the charging effect of the vehicle and the energy storage device.

[0010] In some embodiments, the first power conversion unit and the second power conversion unit are unidirectional ACDC (Alternating Current-Direct Current, AC-DC) conversion units, and the second power conversion unit is a unidirectional DCDC (Direct Current-Direct Current, DC-DC) conversion unit; or, the first power conversion unit is a bidirectional ACDC conversion unit or a bidirectional DCDC conversion unit. In this way, unidirectional or bidirectional flow of energy can be achieved, which can be applied to energy requirements in different application scenarios and ensure charging effect.

[0011] In some embodiments, the first power supply input interface and the first power supply interface are connected in a plug-in manner, so that the connection method between the first power supply input interface and the first power supply interface is simple and the charging process is more convenient.

[0012] In some embodiments, one of the first power supply input interface and the first power supply interface is a plug, and the other is a socket, so that the connection between the first power supply input interface and the first power supply interface is simple and the charging process is more convenient.

[0013] In some embodiments, the second power supply input interface and the second power supply interface are connected in a docking manner. In this way, the second power supply input interface and the second power supply interface can be automatically docked without manual operation, thereby avoiding the situation where the energy storage device feeds power after charging the vehicle due to the user forgetting to connect the second power supply input interface and the second power supply interface during use.

[0014] In some embodiments, the second power supply input interface and the second power supply interface are conductive sheets or conductive blocks. In this way, the second power supply input interface and the second power supply interface can be automatically connected without manual operation, avoiding the situation where the energy storage device feeds power after charging the vehicle due to the user forgetting to connect the second power supply input interface and the second power supply interface during use.

[0015] In some embodiments, the charging system further includes: a plurality of trigger members, the plurality of trigger members being arranged in one-to-one correspondence with the plurality of fixed parking spaces, the plurality of trigger members being configured to trigger the charging pile to move to their respective corresponding first power supply interface and second power supply interface; or, being configured to trigger the first power supply input interface and the second power supply input interface of the charging pile to retract to their respective corresponding first power supply interface and second power supply interface.

[0016] In the charging system, the trigger, fixed parking space, first power supply interface, and second power supply interface are set in one-to-one correspondence. When the vehicle needs to be charged, the trigger is controlled to send a trigger signal to the charging pile. The charging pile can determine the target position based on the received trigger signal. At this time, the charging pile can be moved to the target position as a whole, or only the first power supply input interface and the second power supply input interface of the charging pile can be controlled to be extended to the target position, so that the first power supply input interface of the charging pile is connected to the target first power supply interface, and the second power supply input interface of the charging pile is connected to the target second power supply interface for charging. The charging pile can realize the automatic movement of the charging pile or the first power supply input interface and the second power supply input interface of the charging pile based on the status of multiple triggers, making the charging process more convenient.

[0017] In some embodiments, the trigger is a parking information identifier including parking information, the charging pile is also connected to the terminal device for communication, the terminal device is configured to obtain the parking information based on the parking information identifier, and the charging pile is also configured to automatically move to the target first power supply interface and the target second power supply interface based on the parking information of the target parking space sent by the terminal device; or, the charging pile is also configured to control its own first power supply input interface and second power supply input interface to be extended to the target first power supply interface and the target second power supply interface based on the parking information of the target parking space sent by the terminal device. The parking information of the target parking space is obtained by identifying the parking information identifier of the target parking space through the terminal device, and the parking information of the target parking space is sent to the charging pile based on wireless communication. The charging pile automatically moves to the target power supply interface of the target parking space according to the received parking information of the target parking space, or controls its first power supply input interface and second power supply input interface to move to the target power supply interface of the target parking space, so that the charging process is more convenient.

[0018] In some embodiments, the parking space information is identified as a barcode or a QR code. In this way, the parking space information of the target parking space can be obtained by scanning the barcode or QR code of the target parking space through the terminal device, and the parking space information of the target parking space is sent to the charging pile through the terminal device based on wireless communication, so that the charging pile automatically moves to the target power supply interface of the target parking space according to the received parking space information of the target parking space, or controls its own first power supply input interface and second power supply input interface to automatically retract to the target power supply interface, making the charging process more convenient.

[0019] In some embodiments, the trigger is a parking switch, which is connected to the charging pile, and the charging pile is also configured to automatically move to the target first power supply interface and the target second power supply interface when the state of the parking switch corresponding to the target parking space is the target state; or, the charging pile is also configured to control its own first power supply input interface and second power supply input interface to be retracted to the target first power supply interface and the target second power supply interface when the state of the parking switch corresponding to the target parking space is the target state.

[0020] The parking switch and the charging pile can be connected by wire or by wireless. For example, when the parking switch is a mechanical switch, the mechanical switch is set on one side of the corresponding fixed parking space, and the state of the mechanical switch is transmitted to the charging pile by wire; when the parking switch is an electronic switch, such as a pressure sensor, infrared sensor, etc., the vehicle in the corresponding parking space is detected by the electronic switch, and the detection result is sent to the charging pile by wire or wireless. When the charging pile recognizes that the state of the parking switch is the target state, the fixed parking space corresponding to the parking switch in the target state is used as the target parking space, and automatically moves to the target power supply interface corresponding to the target parking space, or controls its own first power supply input interface and second power supply input interface to automatically retract to the target power supply interface, making the charging process more convenient.

[0021] In some embodiments, the parking switch includes at least one of a mechanical switch, a pressure sensor, and an infrared sensor. When the charging pile recognizes that the state of the parking switch is the target state, it determines the target parking space based on the parking switch and automatically moves to the target power supply interface corresponding to the target parking space, or controls its own first power supply input interface and second power supply input interface to automatically extend to the target power supply interface, making the charging process more convenient.

[0022] In some embodiments, the charging pile is further provided with a sensing device and a moving device, and the charging pile is further configured to control the moving device to automatically move to the target first power supply interface and the target second power supply interface based on the surrounding environment information sensed by the sensing device; or, the charging pile is further provided with a sensing device and a telescopic device, and the charging pile is further configured to control the telescopic device to drive the first power input interface and the second power input interface to telescope to the target first power supply interface and the target second power supply interface based on the surrounding environment information sensed by the sensing device. The charging pile can automatically move to the target power supply interface through the sensing device and the moving device, or can control its own first power supply input interface and second power supply input interface to telescope to the target first power supply interface and the target second power supply interface through the sensing device and the telescopic device, without the need for human operation, making the charging process more convenient.

[0023] In some embodiments, the charging system further includes: a mobile route identifier, a plurality of pile position identifiers are provided on the mobile route identifier, and the plurality of pile position identifiers are arranged in one-to-one correspondence with the plurality of first power supply interfaces, and the charging pile is further configured to control the mobile device to automatically move to the target pile position identifier corresponding to the target first power supply interface based on the surrounding environment information perceived by the sensing device; or, the charging pile is further configured to control the telescopic device to drive the first power supply input interface to telescope to the target pile position identifier corresponding to the target first power supply interface based on the surrounding environment information perceived by the sensing device. The charging pile moves quickly to the target power supply interface directly based on the mobile route identifier, which not only improves the moving speed, but also does not require the laying of guide rails, saving costs.

[0024] In some embodiments, the number of the charging piles is greater than 1 and less than the number of the plurality of fixed parking spaces. In this way, multiple vehicles can be charged simultaneously through the plurality of charging piles, thereby meeting the need for charging multiple vehicles simultaneously.

[0043] At present, in electric vehicle charging stations, one charging pile is installed for each parking space. This installation solution leads to high initial investment costs for charging stations. At the same time, in actual applications, the utilization rate of charging piles is low and the actual idle rate is high, resulting in a long investment recovery period and failure to make quick profits.

[0044] To this end, the present application proposes a charging system. In the technical solution of the present application, multiple first power supply interfaces are arranged in one-to-one correspondence with multiple fixed parking spaces. The multiple first power supply interfaces are connected to the power supply through a power supply device. When the vehicle has a charging demand, the vehicle is parked in one of the fixed parking spaces, and the charging pile is moved to the target first power supply interface corresponding to the fixed parking space, or the first power supply input interface of the charging pile is extended to the target first power supply interface. The owner connects the first power supply input interface of the charging pile with the target first power supply interface, and the power supply output interface of the charging pile, i.e., the charging gun, is connected to the charging port of the vehicle to charge the vehicle. During the charging process, the vehicle can be charged only by the first charging power provided by the power supply, or only by the second charging power provided by the energy storage device in the charging pile, or the vehicle can be charged simultaneously by the first charging power provided by the power supply and the second charging power provided by the energy storage device in the charging pile, so as to achieve high-power charging. The specific control strategy can be set based on the actual situation. This technical solution solves the problems of too high idle rate of charging piles and excessive overall economic investment in the charging station design scheme of setting up one charging pile for one parking space through charging piles. At the same time, based on the charging piles, the charging needs of vehicles in different parking spaces can be met, the number of installed charging piles can be reduced, and the cost can be reduced. In addition, during the charging process, the vehicle can be charged by controlling one or more of the energy storage device and the power supply to provide charging energy, which can meet different charging power requirements and different scenario requirements and ensure the charging effect.

[0045] For the convenience of explanation, the following embodiments are combined Figure 1 The charging system of the present application is described.

[0046] like Figure 1 As shown, the charging system 100 of the present application is used to provide charging services to multiple fixed parking spaces. The charging system 100 may include: a charging pile 10, multiple first power supply interfaces 20 and a power supply device 30.

[0047] Among them, the charging pile 10 is provided with a first power supply input interface 11 and an energy storage device 12. Multiple first power supply interfaces 20 are arranged in a one-to-one correspondence with multiple fixed parking spaces. The power supply device 30 is connected to the multiple first power supply interfaces 20 and the power supply 200, and is configured to output the first charging power to the multiple first power supply interfaces 20 based on the power of the power supply. Among them, when the charging pile 10 moves to the target first power supply interface and the first power supply input interface 11 of the charging pile 10 is connected to the target first power supply interface, or the first power supply input interface 11 of the charging pile 10 is retracted to the target first power supply interface and connected to the target first power supply interface, the charging pile 10 charges the vehicle in the target parking space corresponding to the target first power supply interface based on the first charging power and / or the second charging power provided by the energy storage device 12.

[0048] Specifically, the charging pile 10 can be moved according to demand, and its movement mode can be manual pushing, or it can be automatically moved based on a trigger instruction, or the first power supply input interface 11 of the charging pile 10 can be extended and retracted according to demand, and its extension mode can be manual traction, or it can be automatically moved based on a trigger instruction, without specific restrictions. An energy storage device 12 is provided in the charging pile 10, and the energy storage device 12 is used to convert electrical energy into chemical energy and store it in a battery, and is composed of a plurality of batteries. The charging pile 10 also has a charging output interface 13 such as a charging gun, which is connected to the charging port of the vehicle through the charging gun to charge the vehicle. In the charging pile 10, the first power supply input interface 11 and the energy storage device 12 are suitable for connecting to the charging output interface 13. For example, the first power supply input interface 11 and the energy storage device 12 are connected to the charging output interface 13 through a voltage conversion unit, so as to convert the first charging electric energy and the second charging electric energy into a target voltage through the voltage conversion unit to charge the vehicle. In addition, the charging pile 10 may not only have the function of power conversion, such as stepping down the received first charging power to charge the vehicle, but may also have functions such as charging monitoring, such as real-time monitoring of vehicle power demand, charging voltage, charging current, charging time and other working parameters during the charging process to control the charging process.

[0049] The first power supply interface 20 is arranged in one-to-one correspondence with the fixed parking space, and is arranged near the corresponding fixed parking space, and is used to connect to the power supply input interface 11 of the charging pile 10. At the same time, multiple first power supply interfaces 20 are connected to the power supply 200 through the power supply device 30, wherein the power supply 200 can be an AC power grid, a photovoltaic power generation system, etc., for providing electrical energy.

[0050] The power supply device 30 is an electric energy conversion device, which is used to convert the electric energy provided by the power supply source 200 into the first charging electric energy, and then provide the first charging electric energy to the charging pile 10 through the first power supply interface 20 for vehicle charging. In addition, in addition to supplying power to the charging pile 10 through the first power supply interface 20, the power supply device 30 also communicates with the charging pile 10 through the first power supply interface 20. The communication content may include vehicle power requirements, real-time charging working parameters, etc. Then, during the charging process, the power supply device 30 can control the output power of the current power supply source 200 based on the vehicle power requirements to ensure the charging quality.

[0051] When the vehicle needs to be charged, the user parks the vehicle in the corresponding fixed parking space, and the first power supply interface 20 corresponding to the fixed parking space is the target first power supply interface. When the charging pile 10 moves to the target first power supply interface, or the first power supply input interface 11 of the charging pile 10 is extended to the target first power supply interface, the owner connects the first power supply input interface 11 of the charging pile 10 with the target first power supply interface, and connects the charging gun of the charging pile 10 with the charging port of the vehicle. At this time, the vehicle to be charged establishes a charging circuit through the charging pile 10, the target first power supply interface, the power supply device 30 and the power supply 200, and then performs vehicle charging. During the charging process, the vehicle can be charged only based on the first charging power provided by the power supply 200. For example, when the stored power in the energy storage device 12 is less than the preset power lower limit, the vehicle is charged by the first charging power provided by the power supply 200. The vehicle can also be charged only based on the second charging power provided by the energy storage device 12. For example, when the output of the power supply 200 is unstable or the output power does not reach the preset charging condition, and the stored power in the energy storage device 12 reaches the preset power threshold, the vehicle is charged by the energy storage device 12. The vehicle can also be charged based on the first charging power provided by the power supply 200 and the second charging power provided by the energy storage device 12 at the same time. For example, when the output power of the power supply 200 cannot meet the high-power charging demand of the vehicle, the power supply 200 and the energy storage device 12 jointly charge the vehicle to achieve high-power charging. The specific control strategy can be set based on the actual situation.

[0052] This technical solution solves the problems of high idle rate of charging piles and excessive overall economic investment in the design scheme of one-to-one correspondence between charging piles and parking spaces through charging piles. At the same time, during the charging process, the vehicle is charged by controlling one or more of the energy storage device and the power supply, which can meet different charging power requirements and application scenarios and ensure the charging effect.

[0053] In some embodiments of the present application, Figure 2 As shown, the charging pile 10 is also provided with a second power supply input interface 14, and the charging system 100 also includes multiple second power supply interfaces 40, and the multiple second power supply interfaces 40 are arranged one-to-one with the multiple first power supply interfaces 20. The power supply device 30 is also connected to the multiple second power supply interfaces 40, and outputs the third charging power to the multiple second power supply interfaces 40 based on the power of the power supply 200; wherein, when the charging pile 10 moves to the target second power supply interface and the second power supply input interface 14 of the charging pile 10 is connected to the target second power supply interface, or the second power supply input interface 14 of the charging pile 10 is retracted to the target second power supply interface and connected to the target second power supply interface, the charging pile 10 also charges the energy storage device 12 based on the third charging power; wherein, the target second power supply interface corresponds to the target first power supply interface.

[0054] Specifically, the first power supply interface 20, the second power supply interface 40 and the fixed parking space are set in a one-to-one correspondence. When the charging pile 10 moves to the target first power supply interface and the target second power supply interface, or when the first power supply input interface 11 and the second power supply input interface 14 of the charging pile 10 are extended to the target first power supply interface and the target second power supply interface, the first power supply input interface 11 of the charging pile 10 is connected to the target first power supply interface, the second power supply input interface 14 is connected to the target second power supply interface, and the charging output interface 13 is connected to the charging port of the vehicle to charge the vehicle.

[0055] Exemplarily, during the charging process, if the output power of the power supply 200 can meet the power demand of the vehicle, the vehicle is charged only based on the first charging power provided by the power supply 200, and the power in the energy storage device 14 is judged at the same time. If the power in the energy storage device 14 is not full, the power supply device 300 converts the excess power provided by the power supply 200 into the third charging power to charge the energy storage device 14. At this time, the vehicle charging and the energy storage device 14 can be charged at the same time, and the specific power distribution can be set according to the actual situation. In addition, after the charging of the vehicle is completed, the power supply device 30 can convert the power provided by the power supply device 200 into the third charging power to charge the energy storage device 14 until the energy storage device 14 is fully charged and the charging is completed.

[0056] This embodiment can automatically recharge the energy storage device 14 through the power supply 200, so that the energy storage device 14 has sufficient electricity, providing a guarantee for the charging effect. At the same time, there is no need to manually recharge the energy storage device 14, which reduces labor costs and makes the charging process more convenient.

[0057] In some embodiments of the present application, the power supply device 30 includes: a first power conversion unit 31, one end of the first power conversion unit 31 is connected to the AC power grid; a second power conversion unit 32, one end of the second power conversion unit 32 is connected to the other end of the first power conversion unit 31, and the other end of the second power conversion unit 32 is connected to multiple first power supply interfaces and multiple second power supply interfaces 40; wherein, through the first power conversion unit 31 and the second power conversion unit 32, the first charging power and the third charging power are output based on the power of the AC power grid.

[0058] Specifically, this embodiment uses an AC power grid as the power supply 200, and the AC power grid is used to provide AC power. The first power conversion unit 31 is used to convert the AC power provided by the AC power grid into DC power, and the second power conversion unit 32 is used to convert the DC power output by the first power conversion unit 31 into a voltage to output the first charging power and the third charging power of the target voltage, wherein the voltage of the first charging power and the third charging power can be the same or different, and can be specifically applied based on actual conditions. In this way, the electric energy of the AC power grid is converted into charging power output by the first power conversion unit 31 and the second power conversion unit 32 to meet the charging needs in different scenarios and ensure the charging effect of the vehicle.

[0059] In some embodiments of the present application, the first power conversion unit 31 is a unidirectional ACDC conversion unit, and the second power conversion unit 32 is a unidirectional DCDC conversion unit; or, the first power conversion unit is a unidirectional ACDC conversion unit, and the second power conversion unit 32 is a bidirectional DCDC conversion unit.

[0060] Specifically, when the first power conversion unit 31 is a unidirectional ACDC conversion unit, the AC power provided by the AC grid can only be converted into DC power for output through the first power conversion unit 31. When the first power conversion unit 31 is a bidirectional ACDC conversion unit, in addition to converting the AC power provided by the AC grid into DC power for output through the first power conversion unit 31, the DC power can also be converted into AC power for output to the AC grid through the first power conversion unit 31.

[0061] When the second power conversion unit 32 is a unidirectional DCDC conversion unit, electric energy can only be output from the first power conversion unit 31 to the first power supply interface 20 and the second power supply interface 40 through the second power conversion unit 32. When the second power conversion unit 32 is a bidirectional DCDC conversion unit, bidirectional flow of electric energy between the first power conversion unit 31 and the power supply interface can be achieved.

[0062] For example, when the power supply device 30 adopts the first power conversion unit 31 as a unidirectional ACDC conversion unit and the second power conversion unit 32 as a unidirectional DCDC conversion unit, charging power is provided to the first power supply interface 20 and the second power supply interface 40 based on the AC power grid; when the power supply device 30 adopts the first power conversion unit 31 as a bidirectional ACDC conversion unit and the second power conversion unit 32 as a bidirectional DCDC conversion unit, in addition to providing charging power to the first power supply interface 20 and the second power supply interface 40 through the AC power grid, external DC power can also be input into the AC power grid to realize the bidirectional flow of electric energy between the power supply interface and the power supply 200.

[0063] This embodiment can realize unidirectional or bidirectional flow of energy to adapt to the energy requirements in different application scenarios, thereby improving vehicle charging effect and application flexibility.

[0064] In some embodiments of the present application, the first power input interface 11 and the first power interface 20 are connected in a plug-in manner.

[0065] One of the first power supply input interface 11 and the first power supply interface 20 is a socket, and the other is a corresponding plug. For example, the first power supply input interface 11 is a plug, and the first power supply interface 20 is a socket; or, the first power supply input interface 11 is a socket, and the first power supply interface 20 is a plug, which can be applied according to actual conditions. The first power supply input interface 11 and the first power supply interface 20 are connected by plugging, which can reduce the difficulty of docking the first power supply input interface 11 and the first power supply interface 20, reduce the application cost, and solve the problem of high difficulty in automated docking and high contact internal resistance in the scheme of directly docking the charging pile with the positive and negative poles of the power supply at the parking space position compared to the related technology, which cannot meet the high-power charging requirements of existing electric vehicles.

[0066] In some embodiments of the present application, the second power supply input interface 14 and the second power supply interface 40 are connected in a docking manner. For example, the second power supply input interface 14 and the second power supply interface 40 are conductive sheets or conductive blocks.

[0067] The second power supply input interface 14 and the second power supply interface 40 can be automatically connected without manual operation, avoiding the situation where the energy storage device 14 feeds power after charging the vehicle due to the user forgetting to connect the second power supply input interface 14 and the second power supply interface 40 during use.

[0068] In some embodiments of the present application, Figure 3 As shown, the charging system 100 also includes: a plurality of trigger members 50, the plurality of trigger members 50 are arranged in one-to-one correspondence with a plurality of fixed parking spaces, and the plurality of trigger members 50 are configured to trigger the charging pile to move to the respective corresponding first power supply interface 20 and second power supply interface 40; or, are configured to trigger the first power supply input interface 11 and second power supply input interface 14 of the charging pile to retract to the respective corresponding first power supply interface 20 and second power supply interface 40.

[0069] Specifically, the trigger member 50 , the fixed parking space, the first power supply interface 20 , and the second power supply interface 40 are arranged in a one-to-one correspondence.

[0070] The trigger 50 is used to trigger the charging pile 10 to move to the corresponding power supply interface, or to trigger the first power supply input interface 11 and the second power supply input interface 14 of the charging pile to the first power supply interface 20 and the second power supply interface 40 respectively corresponding to each other. Among them, the trigger 50 can be a device that can send a corresponding trigger signal by itself, or it can be used as an intermediate medium for generating a corresponding trigger signal. For example, the trigger 50 can be a mechanical switch, which is connected to the charging pile 10 by wire. At this time, the trigger 50 can be manually controlled to be closed or disconnected, so as to output a corresponding trigger signal to the charging pile 10 by itself; the trigger 50 can also be a detection sensor, which is wirelessly connected to the charging pile 10. At this time, the detection sensor can automatically detect whether there is a vehicle parked in the parking space, so as to output a corresponding trigger signal to the charging pile 10 by itself; the trigger 50 can also be a two-dimensional code, a radio frequency tag, etc. that stores location information, as an intermediate medium for generating a trigger signal. At this time, the user scans and identifies the trigger 50 through a mobile phone and sends a corresponding trigger signal to the charging pile 10.

[0071] It can be understood that the trigger signal includes location information. After receiving the trigger signal, the charging pile 10 can determine the target position, that is, the fixed parking space corresponding to the trigger signal, based on signal analysis, so that the charging pile 10 moves to the respective corresponding first power supply interface 20 and second power supply interface 40 based on the trigger signal, or the charging pile 10 retracts the first power supply input interface 11 and the second power supply input interface 14 to the respective corresponding first power supply interface 20 and second power supply interface 4 based on the trigger signal to perform subsequent vehicle charging.

[0072] This embodiment can automatically move the charging pile 10 to the target position, or automatically extend the first power input interface 11 and the second power input interface 14 of the charging pile 10 to the target position by setting the multiple triggering components 50, so as to make the charging process more convenient.

[0073] In some embodiments of the present application, the trigger 50 is a parking space information identifier that includes parking space information, the charging pile 10 is also communicatively connected to the terminal device, and the charging pile 10 is also configured to automatically move to the target first power supply interface and the target second power supply interface based on the parking space information of the target parking space sent by the terminal device; or, the charging pile 10 is also configured to control its own first power supply input interface 11 and the second power supply input interface 14 to be retracted to the target first power supply interface and the target second power supply interface based on the parking space information of the target parking space sent by the terminal device.

[0074] Specifically, the parking space information identifier is a carrier for storing parking space information, such as a barcode, a QR code, a radio frequency tag, etc. The terminal device is a device terminal that can identify the parking space information identifier, such as a mobile phone equipped with a target APP (Appl ication, mobile phone software).

[0075] Taking the parking space information identified as a QR code as an example, assuming that the user parks the vehicle in a fixed parking space numbered O2, and then the user scans and identifies the QR code of the parking space through a mobile phone, obtains the parking space information stored in the QR code, i.e., serial number 02, and generates a trigger signal based on the parking space information and sends it to the charging pile 10. The charging pile 10 wakes up upon receiving the trigger signal, and parses the received trigger signal to obtain the parking space information, and then automatically moves to the first power supply interface or the second power supply interface corresponding to the parking space 02, or controls its own first power supply input interface 11 to extend to the first power supply interface corresponding to the parking space 02. , the second power supply input interface 14 is retracted to the second power supply interface corresponding to the parking space 02, the user connects the first charging input interface 11 of the charging pile 10 to the first power supply interface 20 of the parking space 02, connects the second charging input interface 12 of the charging pile 10 to the second power supply interface 40 of the parking space 02, and connects the charging gun of the charging pile 10 to the charging port of the vehicle, so as to charge the vehicle through the first charging power provided by the power supply 200 and / or the second charging power provided by the energy storage device 14, and replenish the energy storage device 14 with the third charging power provided by the power supply unit 200.

[0076] Thus, the parking space information identifier of the target parking space is identified by the terminal device to obtain the parking space information of the target parking space, and the parking space information of the target parking space is sent to the charging pile based on wireless communication. The charging pile 10 automatically moves to the target first power supply interface and the target second power supply interface of the target parking space according to the received parking space information of the target parking space, or controls its own first power supply input interface and the second power supply input interface to be retracted to the target first power supply interface and the target second power supply interface based on the parking space information of the target parking space sent by the terminal device, making the charging process more convenient.

[0077] In some embodiments of the present application, the trigger 50 is a parking switch, which is connected to the charging pile, and the charging pile is also configured to automatically move to the target first power supply interface and the target second power supply interface when the state of the parking switch corresponding to the target parking space is the target state; or, the charging pile 10 is also configured to control its own first power supply input interface 11 and the second power supply input interface 14 to be retracted to the target first power supply interface and the target second power supply interface when the state of the parking switch corresponding to the target parking space is the target state.

[0078] Specifically, the parking switch can be a mechanical switch or an electronic switch, and the parking switch can be set at the parking pile or at the parking space. The connection between the parking switch and the charging pile 10 can be wireless or wired. For example, when the parking switch is a mechanical switch, the mechanical switch is set on one side of the corresponding parking space, and the user controls the opening or closing of the mechanical switch. At this time, the state of the mechanical switch is transmitted to the charging pile 10 by wire; when the parking switch is an infrared sensor, the infrared sensor can be set on one side of the corresponding parking space, and the infrared sensor is used to automatically identify whether a vehicle is parked in the corresponding parking space. At this time, it is sent to the charging pile 10 by wire or wireless; when the parking switch is a pressure sensor, the pressure sensor is set in a fixed parking space, and pressure detection is used to determine whether a vehicle enters. At this time, it can be transmitted to the charging pile 10 by wire or wireless.

[0079] The target state is used to characterize that there is a charging demand at the corresponding position. For example, when the parking switch is a mechanical switch, the closed state of the mechanical switch is the target state. After the mechanical switch is pressed by a person, the target state is transmitted to the charging pile 10 by wire, and the charging pile 10 is awakened and automatically moves to the target first power supply interface and the target second power supply interface, or controls its own first power supply input interface 11 and second power supply input interface 14 to extend to the target first power supply interface and the target second power supply interface, so as to charge the vehicle through the first charging power provided by the power supply 200 and / or the second charging power provided by the energy storage device 14, and to supplement the energy storage device 14 with the third charging power provided by the power supply unit 200.

[0080] When the charging pile 10 recognizes that the state of the parking switch is the target state, it takes the fixed parking space corresponding to the parking switch in the target state as the target parking space, and automatically moves to the target first power supply interface corresponding to the target parking space, or controls its own first power supply input interface 11 and second power supply input interface 14 to be retracted to the target first power supply interface and the target second power supply interface, making the charging process more convenient.

[0081] In some embodiments of the present application, the parking switch includes at least one of a mechanical switch, a pressure sensor, and an infrared sensor.

[0082] Specifically, the parking switch of each fixed parking space can adopt one or more of a mechanical switch, a pressure sensor and an infrared sensor. Exemplarily, the parking switch adopts a combination of a mechanical switch and an infrared sensor. When the user correctly parks the vehicle in parking space 02, the infrared sensor of parking space 02 detects that a vehicle has parked in, and at the same time, the user presses the mechanical switch of parking space 02. The charging pile determines that the parking switch of parking space 02 is in the target state based on the infrared detection result of parking space 02 and the closed state of the mechanical switch, and then automatically moves to the first power supply interface of parking space 02 and the second power supply interface of parking space 02, or controls its own first power supply input interface 11 and second power supply input interface 14 to extend to the first power supply interface of parking space 02 and the second power supply interface of parking space 02, so as to charge the vehicle in parking space 02. In this way, when the charging pile 10 recognizes that the state of the parking switch is the target state, it determines the target parking space based on the parking switch, and automatically moves to the target first power supply interface corresponding to the target parking space, or controls its own first power supply input interface 11 and second power supply input interface 14 to retract to the target first power supply interface and the target second power supply interface, making the charging process more convenient.

[0083] In some embodiments of the present application, Figure 4 As shown, the charging pile 10 is also provided with a sensing device 15 and a moving device 16, and the charging pile 10 is also configured to control the moving device 16 to automatically move to the target first power supply interface based on the surrounding environment information sensed by the sensing device 15, or, the charging pile 10 is also provided with a sensing device and a telescopic device, and the charging pile is also configured to control the telescopic device to drive the first power supply input interface 11 and the second power supply input interface 14 to telescope to the target first power supply interface and the target second power supply interface based on the surrounding environment information sensed by the sensing device.

[0084] Specifically, the sensing device 15 is used to detect surrounding environment information, such as whether there are obstacles in the forward direction, current location information, whether the target location has been reached, etc. The sensing device 15 may include a radar, a position sensor, a scanning recognition device, etc. The sensing device 15 may determine the moving route based on the surrounding environment information obtained by identification, so as to control the movement of the mobile device 16 or the telescopic device, and determine whether the target location has been reached. The mobile device 16 may include a control unit, a drive motor, and moving parts such as rollers installed on the charging pile 10 to move the charging pile 10. The telescopic device may include a control unit, a drive motor, and moving parts such as rollers installed on the first power input interface 11 and the second power input interface 12 of the charging pile 10 to enable the first power input interface 11 and the second power input interface 12 to telescopically move.

[0085] In addition, the charging pile 10 may or may not adopt a guide rail structure. For example, when the guide rail structure is adopted, the sensing device 15 may identify the surrounding environment information by identifying the position mark on the guide rail structure, and control the moving device 16 or the telescopic device to move along the guide rail, and the moving device 16 or the telescopic device may include a bottom clamping position that matches the guide rail; when the guide rail structure is not adopted, the sensing device 15 may identify the surrounding environment information through the mark information set in the surrounding area to determine whether the target position has been reached, and then control the moving device 16 or the telescopic device to move.

[0086] In this embodiment, the charging pile 10 automatically moves to the target power supply interface through the sensing device 15 and the moving device 16, or controls its own first power supply input interface 11 and the second power supply input interface 12 to extend to the target power supply interface through the sensing device 15 and the telescopic device, without the need for human intervention, making the charging process more convenient.

[0087] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the charging system 100 also includes: a mobile route identifier 60, on which a plurality of pile position identifiers are arranged, and the plurality of pile position identifiers are arranged in a one-to-one correspondence with the plurality of first power supply interfaces 20, and the charging pile 10 is also configured to control the mobile device 16 to automatically move to the target pile position identifier corresponding to the target first power supply interface based on the surrounding environment information perceived by the sensing device 15; or, the charging pile 10 is also configured to control the telescopic device to drive the first power supply input interface 11 to telescope to the target pile position identifier corresponding to the target first power supply interface based on the surrounding environment information perceived by the sensing device 15.

[0088] Specifically, the moving route mark 60 is used to mark the moving path of the charging pile 10, and the charging pile 10, or the first power input interface 11 and the second power input interface 12 move along the moving route mark 60. The pile position mark is used to mark the parking position of the charging pile 10, or the first power input interface 11 and the second power input interface 12 in each fixed parking space. The pile position mark, the first power interface 20, the second power interface 40 and the fixed parking space correspond one to one. When the charging pile 10 moves to the target first power interface, it stops at the parking position corresponding to the target first power interface, that is, the pile position mark, or controls the telescopic device to drive the first power input interface 11 to telescope to the target pile position mark, so as to facilitate the connection of the power interface and charging.

[0089] Taking five fixed parking spaces and a movable charging pile 10 as an example, the five fixed parking spaces are represented by parking space 01, parking space 02, parking space 03, parking space 04 and parking space 05. Five first power supply interfaces and five second power supply interfaces are respectively provided for the five fixed parking spaces. The mobile route mark 60 is respectively provided with five pile position marks corresponding to the five first power supply interfaces 20, namely pile position 1, pile position 2, pile position 3, pile position 4 and pile position 5. When there is no demand for charging, that is, no vehicle is parked in any of the five parking spaces, the charging pile 10 is parked at a preset position. When there is a demand for charging, the charging pile 10 can be moved to the target position based on a trigger signal. For example, when the parking space switch determines that a vehicle is parked in parking space 02 and charging is required, the charging pile 10 moves along the moving route mark 60, and when position 2 is identified by the sensing device 15, the moving device 16 is controlled to stop running to stop the charging pile 10 at position 2. Then the user connects the first power supply input interface 11 of the charging pile 10 to the first power supply interface of parking space 02, the second power supply input interface 14 to the second power supply interface of parking space 02, and the charging output interface 13 of the charging pile 10, that is, the charging gun, is connected to the charging port of the vehicle to charge the vehicle.

[0090] In this embodiment, the charging pile 10 can be moved to the target position based on the moving route identifier 60, or the first power supply input interface 11 and the second power supply input interface 14 of the charging pile 10 can be controlled to be extended to the target position based on the moving route identifier 60, without the need to lay guide rails, which not only speeds up the movement but also saves costs.

[0091] In some embodiments of the present application, the number of charging piles 10 is greater than 1 and less than the number of multiple fixed parking spaces.

[0092] When there are multiple charging piles 10, the triggering and awakening sequence of the multiple charging piles 10 can be set in advance. The charging piles 10 are awakened according to the preset triggering sequence and moved to the target position to perform the charging process. For example, the preset serial number can be used as the triggering sequence.

[0093] This embodiment can charge multiple vehicles at the same time through multiple charging piles 10, meeting the demand for charging multiple vehicles at the same time.

[0094] As a specific embodiment of the present application, Figure 4 , Figure 5 and Figure 6As shown, the charging system 100 includes five fixed parking spaces, two movable charging piles and a mobile route mark 60, wherein the five fixed parking spaces are represented by parking space 01, parking space 02, parking space 03, parking space 04 and parking space 05 respectively, and a corresponding QR code is set for each fixed parking space as a location identification code, and a first power supply interface and a second power supply interface are provided near each parking space, and the five first power supply interfaces and the five second power supply interfaces are respectively connected to the AC power grid through the power supply device 30. In the power supply device 30, the first power conversion unit 31 is a bidirectional AC / DC conversion unit, and the second power conversion unit 32 is a bidirectional DC / DC conversion unit. The two movable charging piles are charging pile 1 and charging pile 2, respectively. The movable charging piles can move autonomously according to a preset program, and the user can trigger the charging pile to move to the corresponding position by scanning the QR code of the corresponding parking space. The structure of the movable charging pile is shown in FIG. Figure 4 and Figure 5 As shown, it is composed of a power supply output interface 13, a first power supply input interface 11, an energy storage system (not marked in the figure, located inside the charging pile), a second power supply input interface 14, a sensing device 15 and a mobile device 16, wherein the power supply output interface 13 adopts a standard charging interface to realize the power supply from the charging pile to the car; the first power supply input interface 11 adopts a cable plus charging head design scheme, which can manually realize the charging of the charging pile by the power grid; the mobile device 16 is composed of a wheeled mobile platform, including a transmission part, a servo motor, a rechargeable battery, a moving roller 161, etc.; the second power supply input interface 14 is arranged at the bottom of the mobile device 16, which is an automatic docking interface. When the charging pile moves to the corresponding charging position, that is, the target pile position mark, it can realize automatic docking with the second power supply interface next to the target parking space, and whether the charging pile moves to the target pile position mark can be determined based on infrared, short-distance communication, visual recognition and other schemes; the sensing device 15 can adopt a sensing system that can use visual, radar and sonar systems to realize space and environmental perception, and realize autonomous navigation and movement.

[0095] When there is no vehicle charging, as shown in 6, charging pile 1 and charging pile 2 are parked in a fixed standby position. After the owner parks the vehicle to be charged in the target parking space, and obtains the parking space information corresponding to the target parking space through the QR code corresponding to the target parking space, and generates trigger information based on the parking space information and sends it to the charging pile, the charging pile 1 is awakened based on the trigger signal, and identifies the trigger information to determine the target position, and automatically moves to the target pile position mark through the sensing device 15 and the moving device 16. At this time, the user inserts the first power supply input interface of the charging pile 1 into the target first power supply interface, and the second power supply input interface automatically docks with the target second power supply interface, and the charging gun of the charging pile 1 is connected to the charging port of the vehicle to start charging the vehicle.
