[0004] In the above-mentioned charging pile, a large number of DC contactor switches are required, which leads to a high manufacturing cost of the charging pile. Summary of the Invention

[0018] In some possible implementations, the charging pile further includes a controller, and the controller is configured to:

[0019] receiving a charging instruction for a target gun body, wherein the charging instruction carries a target charging power;

[0020] determining a target power module for charging based on the target charging power and the maximum output power of each power module currently in an idle state;

[0021] The target moving module corresponding to the target power module is controlled to drive the corresponding second conductive member to move to a target position, where the target position is a position in contact with the first conductive member corresponding to the target gun body.

[0049] The above drawings illustrate specific embodiments of the present disclosure, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0051] The following explains terms that may appear in the embodiments of the present disclosure.

[0052] Integrated DC charging pile: The power range is 30kW to 400kW (for example, 60kW and 120kW). It is usually a floor-standing design with a larger size. All components (AC / DC module, controller, cooling system, and gun line) are integrated in a single cabinet.

[0053] Split DC charging pile: The power range is from 240kW to megawatt level, and the power cabinet (including multiple AC / DC modules) is physically separated from the charging terminal (gun + control panel).

[0054] Full Matrix Connection: See Figure 6 As shown, each power module is connected to a charging gun via an independent circuit, each with its own independent switch. The full matrix connection design allows a charging gun to be connected to one or more power modules, thereby controlling the output power of the charging gun to meet the varying charging power requirements of different vehicles.

[0055] Copper bar: also known as copper busbar or copper busbar, is a long strip of conductive component made of high-purity copper. Its cross-section is usually designed to be rectangular or chamfered (rounded) rectangular.

[0056] With the development and popularization of new energy vehicles, people's requirements for the charging speed of charging piles in daily life are constantly increasing. Therefore, split DC charging piles with high-power and fast charging characteristics have developed rapidly.

[0057] In related technologies, split-type DC charging piles consist of multiple power modules and multiple charging cables. The power module inputs are connected to the power grid, and the outputs are connected to the charging cables. This allows the module to transfer power from the grid to the charging cables to charge the vehicle. The power module has a maximum output power.

[0058] Each charging gun and each power module are connected by a switch (typically a DC contactor). The maximum output power of multiple power modules in a single charging station can be the same or different. By controlling each switch, and thus the conduction state of the corresponding charging gun and power module, a charging gun input can be selectively connected to the output of one or more power modules. This allows the output power of the charging gun to be controlled to meet the varying charging power requirements of different vehicles.

[0059] Reference Figure 6 As shown, taking a split-type DC charging pile including three power modules and three charging guns as an example, the split-type DC charging pile requires 9 pairs (18) of DC contactor switches to achieve full matrix connection of the power modules and charging guns.

[0060] Therefore, the above-mentioned charging pile requires a large number of DC contactor switches, which leads to a high manufacturing cost of the charging pile.

[0061] Combine Figure 1 As shown, an embodiment of the present disclosure provides a charging pile, which includes multiple charging gun assemblies 1 and multiple power supply assemblies 2.

[0062] The charging gun assembly 1 includes a gun body 11 and a first conductive member 12 that are electrically connected to each other.

[0063] The power supply assembly 2 includes a power supply module 21, a second conductive member 22 and a movable module 23. The power supply module 21 is electrically connected to the second conductive member 22. The movable module 23 is connected to the second conductive member 22. The movable module 23 is used to drive the second conductive member 22 to move so that the second conductive member 22 can contact any first conductive member 12.

[0064] The present disclosure does not impose any specific limitation on the number of charging gun assemblies 1 , and the number can be set based on parameters such as the usage scenario, manufacturing and installation costs of the charging pile.

[0065] The present disclosure does not impose a specific limit on the number of power supply assemblies 2, and the number of power supply assemblies 2 can be adjusted based on parameters such as the heat dissipation performance of the charging pile and the output power requirements of the charging pile. The maximum output power of the power modules 21 in multiple power supply assemblies 2 can be the same or different, and can be specifically set based on the different charging power requirements of the vehicles used in the charging pile.

[0066] Using the charging pile provided by the embodiment of the present disclosure, each power module 21 has a corresponding movable module 23. Through the movement of the movable module 23, the second conductive part 22 corresponding to the power module 21 can contact the first conductive part 12 corresponding to the target gun body 11. The first conductive part 12 corresponding to each gun body 11 can also contact the second conductive part 22 corresponding to one or more power modules 21 at the same time.

[0067] In this way, there is no need to set up high-cost switching components such as DC contactor switches, and it is possible to selectively connect a charging gun assembly 1 to one or more power modules 21. On the basis of achieving a full matrix connection between the charging gun assembly 1 and the power supply assembly 2, the manufacturing cost of the charging pile is reduced.

[0068] At the same time, there is a certain risk of contact adhesion (i.e. the switch cannot be disconnected normally) in the DC contactor switch, especially the magnetic holding DC contactor. When the contacts of the DC contactor switch stick, on the one hand, it may cause the gun body 11 to maintain output (for example: 800V DC), and the user may cause an arc electric shock or port melting when pulling out the gun. On the other hand, it may cause continuous backflow of current and burn the internal electronic components of the charging pile (for example: AC / DC module).

[0069] In the present disclosure, through a motion-type connection method such as the movable module 23, if the first conductive member 12 and the second conductive member 22 are adhered, the first conductive member 12 and the second conductive member 22 can still be forced to disconnect under the drive of the movable module 23, thereby avoiding adverse phenomena such as short circuit and damage of electronic components inside the charging pile due to contact adhesion.

[0070] The following is combined with Figures 2 to 5 The details and functions of the charging pile provided in the embodiment of the present disclosure are described in more detail.

[0071] In some embodiments, the charging pile further includes a shell 3 , which is used to accommodate and fix the charging gun assembly 1 and the power supply assembly 2 .

[0072] The present disclosure does not specifically limit the size of the housing 3 , and it can be matched and set according to parameters such as the size parameters of the charging gun assembly 1 and the power supply assembly 2 , and the installation space limitations of the charging pile.

[0073] The present disclosure does not make any specific restrictions on the material and structure of the shell 3. It can be matched and set according to the basic protection requirements of the charging pile (for example: dust and water resistance requirements, mechanical impact resistance), electrical safety protection requirements (for example: insulation performance, electromagnetic shielding performance), thermal management requirements (for example: heat dissipation performance, temperature resistance), functional integration and user experience requirements, usage scenario environment requirements (for example: ultraviolet protection in high altitude areas, anti-corrosion treatment in coastal areas), manufacturing cost and other parameters.

[0074] In some examples, combined Figure 5 As shown, the charging pile includes a housing 3, in which the charging gun assembly 1 and the power supply assembly 2 are integrated. This charging pile structure is compact and easy to install, making it suitable for use in scenarios with limited space (such as underground parking lots and roadside charging piles). It does not require additional wiring and can be used directly by connecting to the power grid. It is also relatively easy to maintain. Troubleshooting only requires opening the housing 3, making the repair process relatively simple.

[0075] In some examples, the charging pile includes at least two shells 3, multiple power supply components 2 and the first conductive member 12 in the multiple charging gun assemblies 1 are located inside the first shell 3, and the gun body 11 in the multiple charging gun assemblies 1 is located outside the second or remaining multiple shells 3, and the gun body 11 is electrically connected to the first conductive member 12 inside the first shell 3 through the cable inside the corresponding shell 3.

[0076] With such a charging pile structure, on the one hand, the power module 21 can dissipate heat independently (for example: liquid cooling, forced air cooling, etc.), so as to avoid the accumulation of heat in the power module 21 and the inability to dissipate it in time when the charging pile is working; on the other hand, the modular design has strong scalability and can flexibly increase the number of power modules 21 inside the first shell 3; on the other hand, the first shell 3 and the remaining shells 3 can be installed in a dispersed manner. When the user uses the charging pile, he only needs to approach the shell 3 corresponding to the gun body 11, and does not need to approach the shell 3 corresponding to the power supply assembly 2, so as to avoid the risk of fire, explosion, etc. of the power module 21 threatening the user's personal safety.

[0077] In some embodiments, combined Figure 2 As shown, the moving module 23 includes a first driving member 231 , a first transmission member 232 , a second driving member 233 and a second transmission member 234 .

[0078] The first transmission member 232 is connected to the housing 3, the first driving member 231 is in transmission connection with the first transmission member 232, and the first transmission member 232 is connected to the second driving member 233. The first transmission member 232 is used to drive the second driving member 233 to move in the first direction X. The second driving member 233 is in transmission connection with the second transmission member 234, and the second transmission member 234 is connected to the second conductive member 22. The second transmission member 234 is used to drive the second conductive member 22 to move in the second direction Y.

[0079] By using a movable module 23 that can move in two directions (i.e., a first direction X and a second direction Y), it is possible to avoid a single-direction movement trajectory causing the second conductive member 22 to contact the first conductive member 12 corresponding to the non-target gun body 11, thereby preventing the non-target gun body 11 from being connected to the power module 21 and having power output.

[0080] In some embodiments, the first driving member 231 and the second driving member 233 are both servo motors.

[0081] First, the servo motor uses an encoder (such as absolute value / incremental) feedback, and the positioning accuracy can reach ±0.01mm. It also has closed-loop control logic, real-time detection of speed, position, and torque, and automatic error correction, thereby ensuring the precise relative contact between the second conductive part 22 and the first conductive part 12 corresponding to the target gun body 11. Secondly, the servo motor has a fast response speed and can achieve rapid start and stop, which is conducive to the mutual separation of the second conductive part 22 and the first conductive part 12, and reduces the possibility of adhesion between the second conductive part 22 and the first conductive part 12. Then, the servo motor adopts a brushless design (i.e., no carbon brush wear), and has a long working life, which is conducive to the long-term and stable operation of the charging pile. Finally, the servo motor has a high energy efficiency ratio and can recover energy during deceleration. Therefore, the overall power consumption is low, which is conducive to reducing the cost of using the charging pile.

[0082] The present disclosure does not limit the types of components of the first transmission member 232 and the second transmission member 234 , and they can be matched and set according to parameters such as the strength requirements of the mobile module 23 for the transmission member, the movement accuracy of the transmission member, and the difficulty of assembling and debugging the transmission member.

[0083] In some examples, the first transmission member 232 and the second transmission member 234 are both screw-nut mechanisms, which can convert rotational motion into linear motion. The specific situation is as follows: the first transmission member 232 is connected to the housing 3, the screw in the first transmission member 232 is connected to the first drive member 231, the nut in the first transmission member 232 is sleeved on the corresponding screw, the second drive member 233 is connected to the nut in the first transmission member 232, the screw in the second transmission member 234 is connected to the second drive member 233, and the second conductive member 22 is connected to the nut in the second transmission member 234.

[0084] In some examples, the first transmission member 232 and the second transmission member 234 are both gear rack mechanisms, which can convert rotational motion into linear motion. The specific situation is as follows: the first transmission member 232 is connected to the shell 3, the gear in the first transmission member 232 is connected to the first driving member 231, the rack in the first transmission member 232 is meshed with the corresponding gear, the second driving member 233 is connected to the rack in the first transmission member 232, the gear in the second transmission member 234 is connected to the second driving member 233, and the second conductive member 22 is connected to the rack in the second transmission member 234.

[0085] In some examples, the first transmission member 232 and the second transmission member 234 are respectively one of a screw-nut mechanism and a gear rack mechanism. The connection relationship between the screw-nut mechanism and the gear rack mechanism has been described in the above embodiments and will not be repeated here.

[0086] In some embodiments, combined Figure 2 As shown, the first direction X and the second direction Y are perpendicular to each other.

[0087] In this way, on the one hand, the movements in mutually perpendicular directions are independent of each other, and the movement in one direction will not affect the displacement in the other direction, which also simplifies the control logic of the mobile module 23. On the other hand, the mutually perpendicular first direction X and second direction Y are conducive to improving the structural stability of the mobile module 23. The vertical layout can reduce the mechanical coupling of movements in different directions and reduce the vibration of the mobile module 23. On the other hand, the motion errors of the vertical axis will not be linearly superimposed, which can avoid the error transmission of the mobile module 23.

[0088] In some embodiments, combined Figure 2 、 Figure 3 As shown, the first conductive member 12 includes a positive copper bus 12a and a negative copper bus 12b that are spaced apart.

[0089] First, copper has excellent electrical conductivity, and its resistance is much lower than that of other metal materials under the same cross-sectional area, which can reduce energy loss during charging and improve the charging efficiency of the charging pile; second, copper has a high thermal conductivity coefficient and can quickly and promptly transfer heat from the contact point to the corresponding heat dissipation structure; finally, the copper busbar has a long strip structure, which can make it easier for the second conductive parts 22 corresponding to multiple power modules 21 to contact the first conductive part 12 at the same time.

[0090] The present disclosure does not specifically limit the size parameters of the positive copper busbar 12a and the negative copper busbar 12b, and they can be matched and set according to factors such as the target current value design, insulation performance, structural strength requirements, and safety spacing of the copper busbar.

[0091] In some embodiments, combined Figure 4As shown, the power supply assembly 2 further includes an elastic member 24 . The elastic member 24 is located between the second conductive member 22 and the movable module 23 , and is connected to the second conductive member 22 and the movable module 23 .

[0092] When the movable module 23 drives the second conductive member 22 to move in the second direction Y, the second conductive member 22 and the first conductive member 12 first come into contact. Then, as the movable module 23 continues to move in the second direction Y, the elastic member 24 is gradually compressed and generates a rebound force. In this way, the elastic member 24 can buffer the impact force generated when the second conductive member 22 and the first conductive member 12 come into contact, thereby reducing the degree of wear between the second conductive member 22 and the first conductive member 12.

[0093] Under the elastic force of the elastic member 24, the second conductive member 22 and the first conductive member 12 are tightly fitted in the second direction Y. On the one hand, the tight fit can significantly reduce the contact resistance between the second conductive member 22 and the first conductive member 12, thereby reducing the energy loss in the contact area between the second conductive member 22 and the first conductive member 12, and reducing the heat generated in the contact area between the second conductive member 22 and the first conductive member 12, thereby reducing the occurrence of adverse phenomena such as welding and fire; on the other hand, the tight fit can reduce the possibility of arc discharge, thereby avoiding local high temperature and shock waves caused by arc discharge, and avoiding adverse phenomena such as welding, rupture, and splashing between the second conductive member 22 and the first conductive member 12.

[0094] Under the elastic force of the elastic member 24, the second conductive member 22 and the first conductive member 12 can be prevented from relative movement in the first direction X. For example, the movable module 23 may move to a certain extent in the first direction X due to factors such as vibration and external force impact. Under the deformation action of the elastic member 24, the second conductive member 22 can be prevented from moving together with the movable module 23 in the first direction X, thereby realizing the constraint of the relative position of the second conductive member 22 and the first conductive member 12 in the first direction X.

[0095] The present disclosure does not limit the type of elastic member 24 , and the elastic member 24 may be specifically matched and set according to parameters such as the elastic force requirement of the elastic member 24 , the manufacturing cost of the elastic member 24 , and the difficulty of assembly, for example: a spring, an elastic rubber pad, a silicone gasket, or a shape memory alloy member.

[0096] In some examples, the elastic member 24 is a spring.

[0097] Among them, the spring has good anti-fatigue performance, and the production process of the spring is relatively mature and highly standardized, which can reduce the production cost of the charging pile while ensuring the service life of the elastic member 24.

[0098] In some embodiments, the charging station further includes a controller, which is configured to:

[0099] A charging instruction of the target gun body 11 is received, where the charging instruction carries a target charging power.

[0100] Based on the target charging power and the maximum output power of each power supply module 21 currently in an idle state, a target power supply module 21 for charging is determined.

[0101] The target moving module 23 corresponding to the target power module 21 is controlled to drive the corresponding second conductive member 22 to move to a target position, which is a position in contact with the first conductive member 12 corresponding to the target gun body 11 .

[0102] For example, the target charging power in the charging instruction of the target gun body 11 is 240kW, and the maximum output power of each power module 21 currently in idle state is 60kW. The controller determines that four power modules 21 are the target power modules 21 for charging, and controls the target moving modules 23 corresponding to these four power modules 21 to drive the corresponding second conductive members 22 to move to the target position.

[0103] In this way, the second conductive parts 22 corresponding to the four power modules 21 are in contact with the first conductive parts 12 corresponding to the target gun body 11 at the same time, the four power modules 21 all output at a maximum output power of 60kW, the output end of the gun body 11 outputs at 240kW, and the corresponding charging object is charged at the target charging power.

[0104] The controller may be one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), central processing units (CPUs), and other electronic components. The PLDs may be complex programmable logic devices (CPLDs), field-programmable gate arrays (FPGAs), general purpose array logic (GALs), or any combination thereof, and are not specifically limited in the embodiments of the present application.

[0105] In some embodiments, the controller is further configured to: when a charging end condition is met, control the target moving module 23 to drive the corresponding second conductive member 22 to separate from the first conductive member 12 .

[0106] When the charging termination conditions are met, the controller promptly separates the second conductive member 22 from the first conductive member 12. This, on the one hand, prevents the risk of overcharging the charging object and extends its service life. On the other hand, by using the target movement module 23 to promptly separate the second conductive member 22 from the first conductive member 12, it not only prevents electric shock and adhesion caused by prolonged contact between the second conductive member 22 and the first conductive member 12, but also shortens the separation time between the second conductive member 22 and the first conductive member 12, eliminating the hazards of arc discharge.

[0107] At the same time, the second conductive member 22 is separated from the first conductive member 12, which can also reduce the reactive loss of the power module 21 and reduce the cost of using the charging pile.

[0108] In some embodiments, the charging end condition is: receiving a charging end instruction from the target gun body 11; or detecting that the target gun body 11 has no current output within a preset time period.

[0109] In some examples, the charging end instruction can be an instruction sent by the charging object to the target gun body 11 through a preset communication method. For example, the charging object is an electric vehicle, and the vehicle's battery management system (BMS) detects that the vehicle battery has reached a preset power value and sends a preset instruction to the target gun body 11 through a preset communication method. The target gun body 11 receives the preset instruction and sends a charging end instruction to the controller.

[0110] In some examples, the charging end instruction may be a manually input instruction. For example, the user sends a charging end instruction of the target gun body 11 to the controller through an interactive panel installed on the housing 3 .

[0111] In some examples, the preset time length can be 60 seconds. Thus, the timer starts when the target moving module 23 drives the corresponding second conductive member 22 to contact the first conductive member 12. If the target gun body 11 still does not output current after 60 seconds, the controller controls the second conductive member 22 corresponding to the target moving module 23 to separate from the first conductive member 12. At the same time, the controller can also send a prompt message to the user through the interactive panel installed on the housing 3.

[0112] In this way, the user can be prompted that there is an abnormality in the circuit from the power module 21 to the gun body 11 and then to the charging object, for example: the gun body 11 is not correctly plugged into the charging object to achieve electrical connection, or part of the power module 21 is damaged and cannot effectively output power.

[0113] In some embodiments, combined Figure 4 、 Figure 5As shown, the power supply assembly 2 also includes a first contact member 25, which is fixed on the mobile module 23 and electrically connected to the controller. The charging gun assembly 1 also includes a second contact member 13, the relative position of the second contact member 13 and the first conductive member 12 is fixed, and is electrically connected to the controller.

[0114] The controller is also used to: control the target moving module 23 to move along a preset direction, and when it is detected that the first contact member 25 is conductive with the second contact member 13 corresponding to the target gun body 11, it is determined that the target moving module 23 drives the corresponding second conductive member 22 to move to the target position, and controls the target moving module 23 to stop moving.

[0115] The controller determines whether the second conductive member 22 has moved to the target position by monitoring the conductive state of the first contact member 25 and the second contact member 13, and then controls the target moving module 23 to continue or stop moving. This prevents movement errors of the target moving module 23 from causing the second conductive member 22 to fail to effectively contact the first conductive member 12 or excessive compression between the second conductive member 22 and the first conductive member 12.

[0116] In some examples, combined Figure 5 As shown, the second contact member 13 is connected to the housing 3 , and the first conductive member 12 is connected to the housing 3 . Therefore, the relative positions of the second contact member 13 and the first conductive member 12 are fixed.

[0117] In other examples, combined with Figure 4 As shown, the second contact member 13 is connected to the first conductive member 12 , and the second contact member 13 and the first conductive member 12 are insulated from each other, so that the relative positions of the second contact member 13 and the first conductive member 12 are fixed.

[0118] However, the present disclosure is not limited thereto. In the embodiment of the present disclosure, the relative position of the second conductive member 22 and the first conductive member 12 may be detected by using a laser ranging element, an infrared ranging element, a Hall effect sensor, or the like.
