Description
Power supply device and control method, control device and system thereof
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on June 28, 2023, with application number 202310781150.X and invention name “Power supply device and its control method, control device and system”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of wireless charging technology, and more specifically, to a power supply device and a control method, a control device, and a system thereof. Background Art
[0003] As vehicles move toward electrification and intelligentization, wireless power transfer (WPT) technology has rapidly developed and become widely used in vehicle charging due to its convenience, safety, and low maintenance costs. Wireless charging technologies include radio frequency or microwave wireless charging, electromagnetic induction wireless charging, and electromagnetic resonance wireless charging. Electromagnetic induction wireless charging is the most widely used technology. It relies on a high-frequency alternating electromagnetic field between a separate power supply coil and a power receiving coil, inducing an AC current in the receiving coil. After rectification and filtering, the current is used to charge the battery pack of the electric vehicle.
[0004] However, the efficiency and power of electromagnetic induction wireless charging are affected by the offset between the power supply coil and the receiving coil. For example, in a 6.6-kW wireless charging system, if the power supply coil and the receiving coil of a vehicle are offset 10 cm perpendicular to the magnetic field between the two coils, the power loss at the power supply coil, where the power transmitter is located, increases by 82.11% to 591.51 watts compared to when the two coils are aligned perpendicular to the magnetic field between them. This value is similar to the power of a typical household electric kettle, resulting in a maximum surface temperature of 95°C at the power transmitter, potentially igniting low-ignition-point foreign objects such as catkins and even causing burns to humans or animals.
[0005] In view of this, a charging solution that can improve the alignment between the power supply coil and the power receiving coil is in urgent need of development.
[0006] Summary of the Invention
[0007] The present application provides a power supply device and a control method, a control device, and a system thereof, which can adjust the position and / or posture of a power supply coil during charging, thereby improving the alignment between the power supply coil and the power receiving coil.
[0008] In a first aspect, a power supply device is provided, comprising an energy transmitting coil, a support component, and a control component; wherein the energy transmitting coil is used to provide energy to a device to be charged; a first end of the support component is connected to the energy transmitting coil, and a second end of the support component is connected to a first plane, the first plane comprising the surface of the ground or a building in a first charging area; when the energy transmitting coil transmits energy in a first posture, the control component adjusts the posture of the first end of the support component according to a first energy loss to adjust the posture of the energy transmitting coil in the first charging area, wherein the first energy loss is determined based on the energy transmitted by the energy transmitting coil in the first posture and the energy received by the device to be charged.
[0009] In the above technical solution, the power supply device can adjust the position and posture of the energy transmitting coil (such as the power supply coil) based on the energy loss during the charging process. This not only improves the mutual inductance coefficient and charging efficiency between the energy transmitting coil and the energy receiving coil, thereby reducing energy loss during the charging process and thus reducing safety hazards, but also reduces the complexity of aligning the charging position of the device to be charged (such as a vehicle). In addition, adjusting the position and posture of the energy transmitting coil based on energy loss not only ensures that energy loss does not suddenly change during the charging process, but also helps to adapt to different models and different parking positions of devices to be charged.
[0010] The connection between the first end of the supporting component and the energy transmitting coil may be a dynamic connection or a static connection.
[0011] Exemplarily, the control component adjusts the posture of the first end of the support component according to the first energy loss, including: the control component adjusts the position and / or posture angle of the first end of the support component.
[0012] In some possible implementations, the control component adjusts the posture of the first end of the support component so that the energy transmitting coil is parallel to the energy receiving coil of the device to be charged.
[0013] In some possible implementations, the power supply device includes a fixed base connected to the second end of the supporting component, and the second end of the supporting component can be connected to the first plane through the fixed base.
[0014] In combination with the first aspect, in certain implementations of the first aspect, the device further includes a sensor, which is arranged on the energy transmitting coil and is used to detect the magnetic field strength between the energy transmitting coil and the energy receiving coil of the device to be charged; the control component is used to: adjust the position of the first end of the support component according to the first energy loss and the magnetic field strength.
[0015] For example, the sensor may include multiple sensors that are evenly arranged around the energy transmitting coil, for example, evenly arranged on the inner circle of the energy transmitting coil, or evenly arranged on the outer circle of the energy transmitting coil.
[0016] In the above technical solution, the position of the energy transmitting coil is adjusted according to the magnetic field strength and energy loss between the energy transmitting coil and the energy receiving coil during the charging process, which can not only reduce the energy loss, but also increase the magnetic field strength of the induced magnetic field of the energy receiving coil, thereby achieving a balance between energy loss and magnetic field strength.
[0017] In combination with the first aspect, in certain implementations of the first aspect, the control component is configured to: when the first energy loss is greater than or equal to a loss threshold, adjust the position of the first end of the support component to adjust the energy transmitting coil from the first position to a second position, wherein the second energy loss of the energy transmitting coil when providing energy to the device to be charged in the second position is less than the loss threshold, and the magnetic field strength is within a set range.
[0018] In one example, the first energy loss may be power loss, and the loss threshold may be 15% of the power supply, or 20% of the power supply, or other values.
[0019] In another example, the first energy loss may be average power loss, for example, average power loss per minute, and the loss threshold may be 15% of the supplied power, or 20% of the supplied power, or other values.
[0020] In some possible implementations, the setting range of the magnetic field strength may be determined according to the power supply of the power supply device.
[0021] In the above technical solution, controlling and adjusting the position of the energy transmitting coil when the energy loss is greater than or equal to the loss threshold helps save the energy and computing power required to adjust the position of the energy transmitting coil during charging. When the energy loss is less than the loss threshold, adjusting the position of the energy transmitting coil based on the magnetic field strength helps further reduce energy loss during charging and improve charging efficiency.

[0067] The technical solution in this application will be described below with reference to the accompanying drawings.
[0068] As mentioned above, when the power supply coil of the wireless charging system and the power receiving coil of the vehicle shift laterally in a direction perpendicular to the direction of the magnetic field between the two coils, the charging efficiency will be greatly reduced. In actual application scenarios, the power supply coil of the wireless charging system is usually set on the ground, as shown in position 1 in the charging area 3 in Figure 1. Alternatively, the power supply coil of some wireless charging systems may also be set on a wall or charging pile, as shown in position 2 in the charging area 3 in Figure 1. Regardless of the above position of the power supply coil, when the vehicle is parked in the charging area 3 and preparing to charge, it is impossible to quickly and accurately align its power receiving coil with the power supply coil of the wireless charging system.
[0069] In view of this, the embodiments of the present application provide a power supply device and a control method, a control device and a system for the power supply device, which can adjust the position of the power supply coil according to the energy loss during the wireless charging process to improve the alignment of the power supply coil and the power receiving coil in the direction perpendicular to the magnetic field between the two coils, thereby improving the charging efficiency, reducing the energy loss during the charging process, and improving the safety during the wireless charging process.
[0070] FIG2 shows a schematic diagram of the power supply device provided in the present application. As shown in FIG2 , the power supply device includes an energy transmitting coil 100, a support component 200, and a control component (not shown in the figure). The energy transmitting coil 100 is used to provide energy to the device to be charged; the support component 200 includes a first end and a second end, wherein the first end of the support component 200 is connected to the energy transmitting coil 100, and the second end of the support component 200 is connected to the first plane 300 of the first charging area. When the energy transmitting coil 100 transmits energy, the control component controls the position of the first end of the support component 200 according to the energy loss to adjust the position of the energy transmitting coil 100 in the first charging area. The energy loss is determined based on the energy transmitted by the energy transmitting coil 100 and the energy received by the device to be charged (such as a vehicle or an intelligent robot).
[0071] Exemplarily, the first plane 300 may be the ground, or may be the surface of a building, such as a wall or the surface of a charging pile; or, the first plane 300 may be the surface of other objects with supporting capabilities.
[0072] It should be noted that the connection between the support component 200 and the energy transmitting coil 100 can be a dynamic connection or a static connection. The energy transmitting coil 100 includes the above-mentioned power supply coil, and the device to be charged includes an energy receiving coil, which can include the above-mentioned power receiving coil.

[0075] Exemplarily, the power supply device further includes a sensor, which is disposed on the energy transmitting coil 100 and is configured to detect the magnetic field strength between the energy transmitting coil 100 and the energy receiving coil of the device to be charged. The magnetic field strength between the energy transmitting coil 100 and the energy receiving coil can be obtained from the sensor. Alternatively, the magnetic field strength can also be detected by a sensor disposed on the energy receiving coil of the device to be charged.
[0076] Illustratively, the control component may include an electronic control unit (ECU), and the support component 200 may include one or more actuators. In one implementation, the control component is electrically connected to the actuators of the support component 200 and transmits control signals to the actuators of the support component 200 via electrical signals. In another implementation, the control component transmits control signals to the actuators of the support component 200 via a wireless communication network. When the actuators of the support component 200 execute the control signals, the position of the first end of the support component 200 is adjusted, thereby adjusting the position of the energy transmitting coil 100.
[0077] In addition, the control component can communicate with another device (such as a cloud server, a device to be charged, etc.) through a wired or wireless communication network.

In one implementation, the control component can be disposed in the fixed base.
[0080] In some possible implementations, the power supply device further includes a power supply component for providing current to the energy transmitting coil, the power supply component being disposed at the first end of the support member. Alternatively, the power supply component is disposed on the ground or in a charging station, and provides current to the energy transmitting coil via a wiring harness. In one example, the power supply device further includes a wiring harness management component for controlling the length of the wiring harness.

For example, the support component 200 may include a telescopic component 210, a position-limiting component 220, and a position-limiting component 230. The telescopic component 210 includes a first end and a second end. The first end of the telescopic component 210 is connected to the position-limiting component 220, and the second end of the telescopic component 210 is connected to the position-limiting component 230. The position-limiting component 220 is located at the first end of the support component 200, and the position-limiting component 230 is located at the second end of the support component 200. The support component 200 is connected to the energy transmitting coil 100 via the position-limiting component 220, and the support component 200 is connected to the first plane 300 via the position-limiting component 230. The control component can adjust the position of the energy transmitting coil 100 by controlling the axial length of the telescopic component 210; the control component can realize multi-degree-of-freedom rotation of the energy transmitting coil 100, such as three-degree-of-freedom rotation, by controlling the attitude angle of the limiting component 220; the control component can realize multi-degree-of-freedom rotation of the telescopic component 210, such as three-degree-of-freedom rotation, by controlling the attitude angle of the limiting component 230, thereby adjusting the position and attitude of the energy transmitting coil 100.
[0082] In the embodiments of the present application, the attitude angle refers to the angle between the object coordinate system and the ground coordinate system (o-xyz). The attitude angle includes the pitch angle (pitch), roll angle (roll), and heading angle (yaw). The pitch angle is the angle between the x-axis of the object coordinate system and the xoy plane of the ground coordinate system. The roll angle is the angle between the y-axis of the object coordinate system and the xoy plane of the ground coordinate system. The heading angle is the angle between the projection of the x-axis of the object coordinate system on the xoy plane of the ground coordinate system and the y-axis of the ground coordinate system.
[0083] For example, the telescopic component 210 may be in the form of a telescopic structure as shown in FIG2 , such as a pneumatic telescopic rod, a telescopic screw, etc. Alternatively, the telescopic component 210 may be in the form of a planar four-bar structure as shown in FIG4 . The position-limiting components 220 or 230 may be implemented by a stepper motor, a servo motor, or other methods.
[0084] Optionally, the telescopic component 210, the limiting component 220, and the limiting component 230 are all provided with position sensors. In order to adjust the posture of the energy transmitting coil 100, the control component can adjust at least one of the following items according to the position signal fed back by the above-mentioned position sensor: the axial length of the telescopic component 210, the attitude angle of the limiting component 220, and the attitude angle of the limiting component 230.

[0086] In some possible implementations, the support component 200 may include at least two connecting rods, at least one rotating component, and at least one movable component. For example, as shown in FIG5 , the support component 200 may include a connecting rod 240, a connecting rod 250, a rotating component 260, and a movable component 270. The connecting rods 240 and 250 each include a first end and a second end. The first end of the connecting rod 240 is connected to the first end of the connecting rod 250 via the rotating component 260, and the second end of the connecting rod 250 is connected to the movable component 270. The connecting rod 240 is located at the first end of the support component 200, and the movable component 270 is located at the second end of the support component 200. The support component 200 is connected to the energy transmitting coil 100 via the second end of the connecting rod 240, and the support component 200 is connected to the first plane 300 via the movable component 270. By controlling the rotation angle of the rotating component 260, the control component can cause the connecting rod 240 to oscillate back and forth or rotate in a plane parallel to the first plane 300. The control component can control the translation of the first end of the supporting component 200 by controlling the position of the moving component 270 on the first plane 300 .
[0087] Optionally, both the rotating component 260 and the movable component 270 are provided with position sensors. In order to adjust the posture of the energy transmitting coil 100, the control component can adjust at least one of the following items according to the position signal fed back by the above position sensor: the rotation angle of the rotating component 260 and the position of the movable component 270.
[0088] For example, the rotating component 260 may be a bearing, or a cam structure, or other structures capable of controlling the reciprocating swing or circumferential rotation of the connecting rod 240 .
[0089] Exemplarily, the movable part 270 may be a cam structure; or, the movable part 270 may include a slider 271 and a slide rail 272. The arrangement of the slide rail 272 on the first plane 300 may be as shown in FIG6 . In a specific implementation, the slide rail 272 may also be a cross-shaped structure, or may be in other forms. FIG6 is merely an exemplary illustration. The embodiment of the present application does not specifically limit the specific form and length of the slide rail 272. In a specific implementation, the specific form and length of the slide rail 272 may be determined based on the length of the connecting rod 240 and the size of the charging area.
[0090] Optionally, as shown in FIG7 , the connecting rod 250 may also be a retractable connecting rod. The control component may adjust the distance between the energy transmitting coil 100 and the energy coil of the device to be charged in a direction parallel to the magnetic field between the two coils by controlling the length of the retractable connecting rod.
[0091] The structure of the power supply device provided in the present application is introduced above in conjunction with Figures 2 to 7. The specific process of the control method of the power supply device provided in the embodiment of the present application is described in detail below in conjunction with Figure 8.
[0092] The control method 800 shown in FIG8 can be applied to the power supply devices shown in FIG2 to FIG7. For example, the method 800 can be executed by a control component of the power supply device. The method 800 includes S801 and S802.
[0093] S801: When the energy transmitting coil transmits energy in a first posture, a first energy loss is obtained, where the first energy loss is determined based on energy transmitted by the energy transmitting coil in the first posture and energy received by the device to be charged.
[0094] For example, the energy transmitting coil may be the aforementioned energy transmitting coil 100. The device to be charged may be an electric vehicle, or may be another device to be charged.
[0095] It can be understood that the device to be charged receives energy transmitted by the power supply device through the energy receiving coil.
[0096] The energy transmitted by the energy transmitting coil can be determined based on the voltage U1 of the power supply component providing the current to the energy transmitting coil and the current I1 of the energy transmitting coil. The energy received by the device to be charged can be determined based on the charging current I2 and charging voltage U2 of the battery pack of the device to be charged.
[0097] For example, the first energy loss may be determined by a control component of the power supply device, or may be determined by a cloud server that communicates with both the power supply device and the device to be charged.
[0098] For example, the first energy loss may be power loss, or the first energy loss may be average power loss, or the first energy loss may be total power loss over a period of time. The following uses power loss as an example to illustrate a method for determining the first energy loss.
[0099] In one example, during the charging process, the device to be charged uploads the power data of its battery pack to the cloud server, and the cloud server calculates the average charging power P1 of the battery pack over a first period of time based on the power data. The power data includes at least one of the following: the charging current I2 and charging voltage U2 of the battery pack, the state of charge (SOC) of the battery pack, and the state of health (SOH) of the battery pack. The cloud server sends the charging power information to the control component of the power supply device. The control component calculates the average power supply power P2 of the power supply device over the first period of time based on the voltage U1 and current I1, and then calculates the difference between the average power supply power P2 and the average charging power P1, which is the power loss.
[0100] In another example, during charging, the power supply device uploads its supply voltage and current information to a cloud server. The cloud server calculates the supply power based on the supply voltage and current. Furthermore, the cloud server determines the power loss based on the difference between the supply power and the charging power of the battery pack of the device to be charged, and transmits the power loss information to the control component.
[0101] S802: Adjust the posture of the first end of the supporting component according to the first energy loss to adjust the posture of the energy transmitting coil in the first charging area.
[0102] For example, the supporting member may be the supporting member 200. The first charging area may be an area including the first plane 300.
[0103] In some possible implementations, adjusting the posture of the first end of the support component according to the first energy loss includes: adjusting the posture of the first end of the support component when the first energy loss is greater than or equal to a loss threshold.
[0104] In one example, the first energy loss may be power loss, and the loss threshold may be 15% of the power supply, or 20% of the power supply, or other values.
[0105] In another example, the first energy loss may be average power loss, for example, average power loss per minute, and the loss threshold may be 15% of the supplied power, or 20% of the supplied power, or other values.
[0106] In a specific implementation process, the above loss threshold can be determined according to the line loss of the power supply device and the line loss of the device to be charged.
[0107] In some possible implementations, the method further includes: obtaining the magnetic field strength of the magnetic field between the energy transmitting coil and the energy receiving coil of the device to be charged, and adjusting the posture of the first end of the supporting component according to the first energy loss and the magnetic field strength.
[0108] In some possible implementations, the method further includes: when the first energy loss is greater than or equal to a loss threshold, adjusting the position of the first end of the support component, adjusting the position of the energy transmitting coil in the first charging area to a second position, wherein the second energy loss of the energy transmitting coil when providing energy to the device to be charged in the second position is less than the loss threshold, and the magnetic field strength is within a set range.
[0109] For example, based on the first energy loss and / or magnetic field strength, the first end of the support component is controlled to perform a zigzag motion in the area of the energy receiving coil of the device to be charged, thereby determining the second position of the energy transmitting coil. The speed of the zigzag motion of the first end of the support component can be determined based on the operating speed of the algorithm of the control component. It should be noted that during the movement of the first end of the support component, the planes in which the energy transmitting coil and the energy receiving coil are located remain parallel.
[0110] Exemplarily, the control logic for controlling the support component based on the first energy loss and magnetic field strength can be shown in Figure 9. The control component includes a power loss regulator and a magnetic field strength regulator. The difference between the expected power loss and the actual power loss is input into the power loss regulator, which then determines the expected magnetic field strength based on the difference between the expected and actual power losses. The difference between the expected and actual magnetic field strengths is input into the magnetic field strength regulator, so that the magnetic field strength regulator determines a control variable for the support component based on the difference between the expected and actual magnetic field strengths. When the actuator of the support component executes the control variable, the position of the first end of the support component is controlled. Exemplarily, the expected power loss can be the loss threshold, the actual energy loss can be the first energy loss, and the expected magnetic field strength can be within the set range. The table consulted by the power loss regulator can be a table that represents the relationship between the difference between the expected and actual power losses and the expected magnetic field strength. Exemplarily, the specific value of the expected magnetic field strength in the table can be determined based on the number of turns of the energy transmitting / receiving coil, the charging current, and the effective magnetic path length of the energy transmitting / receiving coil. It can be understood that the above-mentioned magnetic field strength is the strength of the superposition of the original magnetic field of the energy transmitting coil and the induced magnetic field generated by the energy receiving coil. Since the strength of the induced magnetic field generated by the energy receiving coil of the device to be charged increases with the improvement of the alignment between the energy transmitting coil and the energy receiving coil, the above-mentioned magnetic field strength increases with the improvement of the alignment between the energy transmitting coil and the energy receiving coil.
[0111] In some possible implementations, when method 800 is applied to any power supply device shown in Figures 2 to 4, adjusting the posture of the first end of the support component includes adjusting at least one of the following: the axial length of the telescopic component 210, the posture angle of the limiting component 220, and the posture angle of the limiting component 230.
[0112] For example, the control component determines the position of the first end of the supporting component at the next moment, such as position 1, based on the first energy loss and / or magnetic field strength, and generates a control amount for at least one of the telescopic component 210, the limiting component 220, and the limiting component 230 based on position 1 and the current position of the supporting component, and sends the control amount to the supporting component. When the supporting component executes the above control amount, the adjustment of the relevant components in the supporting component can be realized, thereby making the position of the first end of the supporting component at the next moment become position 1.
[0113] In some possible implementations, when method 800 is applied to any power supply device shown in Figures 5 to 7, adjusting the posture of the first end of the supporting component includes adjusting at least one of the following: the rotation angle of the rotating component 260, the position of the moving component 270.
[0114] For example, the control component determines the position of the first end of the supporting component at the next moment, such as position 2, based on the first energy loss and / or magnetic field strength, generates a control amount for the rotating component 260 and / or the moving component 270 based on position 2 and the current position of the supporting component, and sends the control amount to the supporting component. When the supporting component executes the above control amount, the adjustment of the relevant components in the supporting component can be realized, thereby making the position of the first end of the supporting component at the next moment become position 2.
[0115] In some possible implementations, when the connecting rod 250 of the power supply device shown in Figures 5 to 7 is a telescopic connecting rod, adjusting the posture of the first end of the supporting component also includes: adjusting the axial length of the connecting rod 250.
[0116] In some possible implementations, the method further includes: obtaining position information of the energy receiving coil of the device to be charged, and adjusting the posture of the first end of the support component according to the position information and the first energy loss. In one example, the position information indicates the approximate position of the energy receiving coil in the device to be charged. For example, taking the device to be charged as a vehicle as an example, the position information may indicate that the energy receiving coil is located on the chassis or the rear of the vehicle. In another example, the position information indicates the precise position of the energy receiving coil in the device to be charged. For example, taking the device to be charged as a vehicle as an example, the position information may indicate the coordinates of the energy receiving coil in the vehicle coordinate system.
[0117] The control method for the power supply device provided in the embodiment of the present application can adjust the position and posture of the energy transmitting coil of the power supply device according to the energy loss during the charging process. This not only improves the mutual induction system between the energy transmitting coil and the energy receiving coil, thereby reducing the energy loss during the charging process, thereby improving charging efficiency and reducing safety hazards, but also reduces the complexity of aligning the charging position of the device to be charged (such as a vehicle). In addition, adjusting the position and posture of the energy transmitting coil according to energy loss not only ensures that the energy loss during the charging process does not change suddenly, but also helps to adapt to devices to be charged of different models and different parking positions.
[0118] It should be noted that those skilled in the art can improve the supporting components of the power supply device based on the above embodiments, such as adding more components or structures to achieve more functions. For example, when the power supply device is installed on the ground, it is still possible to achieve alignment between the energy transmitting coil and the energy receiving coil provided at the tail of the device to be charged (such as a vehicle), or when the power supply device is installed on a wall or the surface of a charging pile, it is still possible to achieve alignment between the energy transmitting coil and the energy receiving coil provided on the chassis of the device to be charged (such as a vehicle). The above implementation methods should also fall within the scope of protection of this application.
