Description

Technical Field

[0001] 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

[0002] As vehicles move toward electrification and intelligence, wireless power transfer (WPT) technology has been rapidly developed and widely used in the field of vehicle charging due to its convenience, safety, and low maintenance costs. Wireless charging technologies include radio frequency or microwave wireless charging technology, electromagnetic induction wireless charging technology, and electromagnetic resonance wireless charging technology. Among them, electromagnetic induction wireless charging technology is widely used. It relies on the high-frequency alternating electromagnetic field between the separated power supply coil and the power receiving coil, thereby inducing an AC current at the power receiving coil, which is rectified and filtered to charge the battery pack of the electric vehicle.

[0003] However, the efficiency and power of electromagnetic induction wireless charging are affected by the offset between the power supply coil and the power receiving coil. For example, when the power supply coil of a 6.6-kilowatt wireless charging system and the power receiving coil of a vehicle are 10 centimeters apart in the direction perpendicular to the magnetic field between the two coils, the loss at the energy transmitting end where the power supply coil is located increases by 82.11% to 591.51 watts compared to when the two coils are aligned in the direction perpendicular to the magnetic field between the two coils. This value is similar to the power of an ordinary household electric kettle, resulting in a maximum surface temperature of 95°C at the energy transmitting end, making it possible to ignite low-ignition-point foreign objects such as catkins, or even burn humans or animals.

[0004] In view of this, a charging solution that can improve the alignment between the power supply coil and the power receiving coil needs to be developed urgently. Summary of the invention

[0005] 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.

[0007] 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) according to the energy loss during the charging process, which can not only improve the mutual inductance coefficient and charging efficiency between the energy transmitting coil and the energy receiving coil, thereby reducing the energy loss during the charging process, thereby reducing safety hazards, but also reduce 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 the energy loss can not only ensure that the energy loss during the charging process will not change suddenly, but also help to adapt to devices to be charged of different models and different parking positions.

[0008] The connection between the first end of the supporting component and the energy transmitting coil may be a dynamic connection or a static connection.

[0016] In an example, the first energy loss may be power loss, and the loss threshold may be 15% of the power supply power, or 20% of the power supply power, or may be other values.

[0017] In another example, the first energy loss may be an average power loss, for example, the 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.

[0065] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0066] As mentioned above, when the power supply coil of the wireless charging system and the power receiving coil of the vehicle are displaced in a direction perpendicular to the magnetic field direction 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, such as Figure 1 Position 1 in the charging area 3 shown. Alternatively, the power supply coil of some wireless charging systems may also be set on the wall or charging pile, such as Figure 1 Position 2 in the charging area 3 is shown. Regardless of the above position where the power supply coil is set, when the vehicle is parked in the charging area 3 and is ready to charge, it is impossible to quickly and accurately align its power receiving coil with the power supply coil of the wireless charging system.

[0067] 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 posture 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.

[0068] Figure 2 Schematic diagram of the power supply device provided by the present application is shown. Figure 2As shown, the power supply device includes an energy transmitting coil 100, a supporting 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 supporting component 200 includes a first end and a second end, wherein the first end of the supporting component 200 is connected to the energy transmitting coil 100, and the second end of the supporting 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 posture of the first end of the supporting component 200 according to the energy loss to adjust the posture of the energy transmitting coil 100 in the first charging area. The energy loss is determined according to 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, etc.).

[0069] 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.

The magnetic field strength between the energy transmitting coil 100 and the energy receiving coil may be obtained from the sensor. Alternatively, the magnetic field strength may also be detected by a sensor disposed at the energy receiving coil of the device to be charged.

[0074] Exemplarily, the control component may include an electronic control unit (ECU), and the support component 200 includes one or more actuators. In one implementation, the control component is electrically connected to the actuator of the support component 200, and sends a control signal to each actuator of the support component 200 through an electrical signal. In another implementation, the control component sends a control signal to each actuator of the support component 200 through a wireless communication network. When the actuator of the support component 200 executes the control signal, the posture of the first end of the support component 200 is adjusted, thereby adjusting the posture of the energy transmitting coil 100.

[0075] 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.

[0078] In some possible implementations, the power supply device further includes a power supply component, which is used to provide current to the energy transmitting coil, and the power supply component is arranged at the first end of the supporting component. Alternatively, the power supply component is arranged on the ground or in the charging pile, and the power supply component provides current to the energy transmitting coil through a wiring harness. In one example, the power supply device further includes a wiring harness management component, which is used to control the length of the wiring harness.

Exemplarily, the support component 200 may include a telescopic component 210, a limiting component 220, and a 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 limiting component 220, and the second end of the telescopic component 210 is connected to the limiting component 230; the limiting component 220 is located at the first end of the support component 200, and the 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 through the limiting component 220, and the support component 200 is connected to the first plane 300 through the 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.

Figure 5 As shown, the support component 200 may include a connecting rod 240, a connecting rod 250, a rotating component 260 and a moving component 270. The connecting rod 240 and the connecting rod 250 respectively 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 through the rotating component 260, and the second end of the connecting rod 250 is connected to the moving component 270; the connecting rod 240 is located at the first end of the support component 200, and the moving 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 through the second end of the connecting rod 240, and the support component 200 is connected to the first plane 300 through the moving component 270. The control component can realize the reciprocating swing or circumferential rotation of the connecting rod 240 in a plane parallel to the first plane 300 by controlling the rotation angle of the rotating component 260. The control component can control the translation of the first end of the support component 200 by controlling the position of the moving component 270 in the first plane 300.

[0085] 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.

[0086] Exemplarily, the rotating component 260 may be a bearing, or may be a cam structure, or may be other structures capable of controlling the reciprocating swing or circumferential rotation of the connecting rod 240 .

[0087] For example, the moving part 270 may be a cam structure; or the moving part 270 may include a slider 271 and a slide rail 272. The slide rail 272 may be arranged on the first plane 300 as follows: Figure 6 In the specific implementation process, the slide rail 272 can also be a cross shape, or can also be other shapes. Figure 6This is only an exemplary description. The embodiment of the present application does not specifically limit the specific shape and length of the slide rail 272. In the specific implementation process, the specific shape and length of the slide rail 272 can be determined according to the length of the connecting rod 240 and the size of the charging area.

[0088] Alternatively, if Figure 7 As shown, the connecting rod 250 may also be a retractable connecting rod. The control component can adjust the distance between the energy transmitting coil 100 and the energy coil of the device to be charged in the direction parallel to the magnetic field between the two coils by controlling the length of the retractable connecting rod.

[0089] Combination of the above Figures 2 to 7 The structure of the power supply device provided by the present application is introduced. Figure 8 The specific process of the control method of the power supply device provided in the embodiment of the present application is described in detail.

[0090] Figure 8 The control method 800 shown can be applied Figures 2 to 7 In the power supply device shown. Exemplarily, the method 800 may be executed by a control component of the power supply device. The method 800 includes S801 and S802.

[0091] S801, when the energy transmitting coil transmits energy in a first posture, obtaining a first energy loss, where the first energy loss is determined according to energy transmitted by the energy transmitting coil in the first posture and energy received by the device to be charged.

[0092] Exemplarily, the energy transmitting coil may be the above energy transmitting coil 100. The device to be charged may be an electric vehicle, or may be other devices to be charged.

[0093] It can be understood that the device to be charged receives energy emitted by the power supply device through the energy receiving coil.

[0094] The energy transmitted by the energy transmitting coil can be determined based on the voltage U1 of the power supply component providing the current for 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.

[0095] Exemplarily, 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.

[0096] Exemplarily, the first energy loss may be power loss, or the first energy loss may be average electric energy loss, or the first energy loss may also be total electric energy loss over a period of time. The following uses power loss as an example to illustrate the method for determining the first energy loss.

[0097] 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 in the first time period 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, and the control component calculates the average power supply power P2 of the power supply device in the first time period based on the voltage U1 and the 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.

[0098] In another example, during the charging process, the power supply device uploads information about its power supply voltage and power supply current to the cloud server. The cloud server calculates the power supply power based on the power supply voltage and power supply current, and then the cloud server determines the power loss based on the difference between the power supply power and the charging power of the battery pack of the device to be charged, and sends the power loss to the control component.

[0099] S802: According to the first energy loss, adjust the posture of the first end of the supporting component to adjust the posture of the energy transmitting coil in the first charging area.

[0100] Exemplarily, the support member may be the support member 200. The first charging area may be an area including the first plane 300.

[0101] In some possible implementations, adjusting the posture of the first end of the support component according to the first energy loss includes: when the first energy loss is greater than or equal to a loss threshold, adjusting the posture of the first end of the support component.

[0102] In an example, the first energy loss may be power loss, and the loss threshold may be 15% of the power supply power, or 20% of the power supply power, or may be other values.

[0103] In another example, the first energy loss may be an average power loss, for example, the 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.

[0104] 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.

[0105] In some possible implementations, the method further includes: acquiring 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.

[0106] In some possible implementations, the method further includes: when the first energy loss is greater than or equal to a loss threshold, adjusting the posture of the first end of the supporting component, adjusting the posture of the energy transmitting coil in the first charging area to a second posture, and the second energy loss of the energy transmitting coil when providing energy to the device to be charged in the second posture is less than the loss threshold, and the magnetic field strength is within a set range.

[0107] Exemplarily, according to 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 where the energy receiving coil of the device to be charged is located, so as to determine the second posture of the energy transmitting coil. The speed of the zigzag motion of the first end of the support component can be determined according to the algorithm running speed of the control component. It should be noted that during the movement of the first end of the support component, the energy transmitting coil remains parallel to the plane where the energy receiving coil is located.

[0108] Exemplarily, the control logic of the control component controlling the support component according to the first energy loss and the magnetic field strength can be as follows: Fig. 9 As shown. Wherein, the control component includes a power loss regulator and a magnetic field strength regulator, and the difference between the expected power loss and the actual power loss is input into the power loss regulator, and the power loss regulator determines the expected magnetic field strength by looking up a table according to the difference between the expected power loss and the actual power loss. The difference between the expected magnetic field strength and the actual magnetic field strength is input into the magnetic field strength regulator, so that the magnetic field strength regulator determines the control amount of the support component according to the difference between the expected magnetic field strength and the actual magnetic field strength, and when the actuator of the support component executes the control amount, the posture of the first end of the support component is controlled. Exemplarily, the expected power loss can be the above-mentioned loss threshold, the actual energy loss can be the above-mentioned first energy loss, and the expected magnetic field strength can be the above-mentioned set range. The table looked up by the above-mentioned power loss regulator can be a table characterizing the relationship between the difference between the expected power loss and the actual power loss and the expected magnetic field strength. Exemplarily, the specific value of the expected magnetic field strength in the above-mentioned table can be determined according to the number of turns of the energy sending / receiving coil, the charging current, and the effective magnetic path length of the energy sending / 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.

[0109] In some possible implementations, when method 800 is applied to Figures 2 to 4 When any of the power supply devices shown in the figure is used, adjusting the posture of the first end of the supporting 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.

[0110] 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 the 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 according to the 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, so that the position of the first end of the supporting component at the next moment becomes position 1.

[0111] In some possible implementations, when method 800 is applied to Figures 5 to 7 When any power supply device shown in the figure is used, 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 and the position of the moving component 270.

[0112] 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 the 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, so that the position of the first end of the supporting component at the next moment becomes position 2.

[0113] In some possible implementations, Figures 5 to 7 When the connecting rod 250 of the power supply device shown in the figure 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.

[0114] 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 of the vehicle 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.

[0115] The control method of 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, which can not only improve the mutual inductance system between the energy transmitting coil and the energy receiving coil, thereby reducing the energy loss during the charging process, thereby improving the charging efficiency and reducing safety hazards, but also reduce 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 the energy loss can not only ensure that the energy loss during the charging process will not change suddenly, but also help to adapt to devices to be charged of different models and different parking positions.

[0116] 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, so as to realize more functions. For example, when the power supply device is installed on the ground, the alignment between the energy transmitting coil and the energy receiving coil arranged at the rear of the device to be charged (such as a vehicle) can still be achieved, or when the power supply device is installed on the wall or the surface of the charging pile, the alignment between the energy transmitting coil and the energy receiving coil arranged on the chassis of the device to be charged (such as a vehicle) can still be achieved. Then the above implementation methods should also fall within the scope of protection of this application.
