Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless charging, in particular to a mutual operation judgment method and device, a wireless charging system and an electric vehicle. BACKGROUND

[0002] An electric vehicle is a vehicle that uses a vehicle-mounted power supply as power, drives wheels by using an electric motor, and meets the requirements of road traffic and safety regulations. The vehicle-mounted power supply in the electric vehicle is usually a storage battery that can be repeatedly charged and discharged. At present, the methods for charging the electric vehicle mainly include contact charging and wireless charging. Compared with contact charging, wireless charging has the advantages of convenient use, no spark and electric shock danger, no mechanical wear and tear, adaptability to various harsh environments and weather, easy realization of unmanned automatic charging and mobile charging, and the like. Therefore, wireless charging is likely to become the mainstream of future electric vehicle charging.

[0003] For an electric vehicle supporting wireless charging, a receiving coil is arranged inside the electric vehicle, which is generally located at the chassis of the electric vehicle. The power transmitting device outside the electric vehicle includes a transmitting coil, which is usually arranged on the ground or buried underground. When wireless charging is performed, the electric vehicle is parked above the transmitting coil, so that the transmitting coil and the receiving coil can be coupled, energy can be transmitted between the transmitting coil and the receiving coil through electromagnetic coupling, and then wireless charging can be realized.

[0004] However, the wireless charging standards in the current electric vehicle industry are not unified, and common wireless charging standards mainly include the Chinese national standard scheme, the international standard scheme of the International Electrotechnical Commission (IEC), the international standard scheme of the International Organization for Standardization (ISO), the American national standard recommended scheme (Society of Automotive Engineers, SAE), and the like. Different charging parameter types and / or charging parameter ranges are further specified under different wireless charging standards. Due to the complex and diverse wireless charging standards in the current electric vehicle industry, the wireless transmitting device may not be able to perform wireless charging on all types of electric vehicles, that is, the wireless transmitting device and some electric vehicles may not be able to interoperate, thereby bringing much inconvenience to electric vehicle users.

[0005] Therefore, the current wireless charging technology still needs further research. SUMMARY

[0006] The application provides an interoperability judgment method and device, a wireless charging system and an electric vehicle. The interoperability judgment method provided by the application can be used to determine whether the wireless transmitting device and the wireless charging device can interoperate, which is beneficial to reduce the inconvenience caused by the wireless transmitting device and the wireless charging device failing to interoperate.

[0007] In a first aspect, the application provides an interoperability judgment method, which can be applied to a wireless transmitting device. The method mainly includes: receiving, by the wireless transmitting device, receiving standard information and receiving parameter information from a wireless receiving device. The receiving standard information can indicate a target charging standard of the wireless receiving device, and the receiving parameter information can indicate a charging receiving parameter in the wireless receiving device that meets the target charging standard. The wireless transmitting device acquires a charging transmitting parameter in the wireless transmitting device that meets the target charging standard when determining a target charging standard supported by the wireless transmitting device according to the receiving standard information. The wireless transmitting device can further determine whether the wireless transmitting device and the wireless receiving device can interoperate according to the charging transmitting parameter and the charging receiving parameter that meet the target charging standard.

[0008] The charging receiving parameter can be understood as a specific implementation of the charging parameter specified by the target charging standard in the wireless receiving device, and the charging transmitting parameter can be understood as a specific implementation of the charging parameter specified by the target charging standard in the wireless transmitting device.

[0009] The charging transmitting parameter includes at least one of the following parameters in the wireless transmitting device: output power level, compensation network structure, self-induction range of the transmitting coil, coupling coefficient range, working frequency range, and maximum adjustable current of the transmitting coil; and / or the charging receiving parameter includes at least one of the following parameters in the wireless receiving device: receiving power level, compensation network structure, ground clearance type of the receiving coil, self-induction range of the receiving coil, coupling coefficient range, working frequency range, and maximum working current of the receiving coil.

[0010] The interoperability judgment method provided by the application can be used to determine whether the wireless transmitting device and the wireless receiving device can interoperate. The wireless transmitting device can determine whether the wireless transmitting device and the wireless receiving device can interoperate before starting charging with the wireless receiving device, so that the wireless transmitting device can not perform wireless charging with the wireless receiving device if the wireless transmitting device and the wireless receiving device cannot interoperate, thereby protecting the safety of the wireless transmitting device and the wireless receiving device and reducing the inconvenience caused by the wireless transmitting device and the wireless receiving device failing to interoperate.

[0011] It can be understood that the wireless transmitting device can determine that the wireless transmitting device and the wireless receiving device cannot interoperate when it is determined according to the received standard information that the wireless transmitting device does not support the target charging standard.

[0012] Generally, the wireless transmitting device and the wireless receiving device can interoperate only when they support the same charging standard. Therefore, the wireless transmitting device can determine that it and the wireless receiving device cannot interoperate after it is determined that the target charging standard is not supported.

[0013] For example, the wireless transmitting device can determine that the wireless transmitting device and the wireless receiving device can interoperate when the charging transmitting parameters and the charging receiving parameters conform to the target charging standard, and the charging transmitting parameters and the charging receiving parameters match, and determine that the wireless transmitting device and the wireless receiving device cannot interoperate when the charging transmitting parameters and the charging receiving parameters conform to the target charging standard, and the charging transmitting parameters and the charging receiving parameters do not match.

[0014] Generally, the wireless transmitting device can have at least one charging transmitting parameter, and the wireless receiving device can have at least one charging receiving parameter. Since the wireless transmitting device and the wireless receiving device both support the target charging standard, the at least one charging transmitting parameter of the wireless transmitting device and the at least one charging receiving parameter of the wireless receiving device can be one-to-one corresponding. The wireless transmitting device can determine whether each charging transmitting parameter and the corresponding charging receiving parameter match according to the corresponding relationship. When all the charging transmitting parameters match the corresponding charging receiving parameters, it can be considered that the wireless transmitting device and the wireless receiving device can interoperate. When at least one charging transmitting parameter does not match the corresponding charging receiving parameter, it can be considered that the wireless transmitting device and the wireless receiving device cannot interoperate.

[0015] Here, the matching of the charging transmitting parameters and the charging receiving parameters can be understood as that the wireless transmitting device can work safely and efficiently when supporting the wireless receiving parameter, and the wireless receiving device can also work safely and efficiently when supporting the wireless transmitting parameter. If the wireless transmitting device cannot work safely and efficiently when supporting the wireless receiving parameter, or the wireless receiving device cannot work safely and efficiently when supporting the wireless transmitting parameter, it can be considered that the charging transmitting parameters and the charging receiving parameters do not match.

[0016] Exemplarily, the receiving standard information can be carried in a first receiving message, the first receiving message comprising at least one receiving standard field, and the at least one receiving standard field corresponding to at least one charging standard in one-to-one correspondence. A value of each receiving standard field is used to indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0017] On this basis, the wireless receiving device can send the receiving standard information to the wireless transmitting device through the first receiving message.

[0018] Exemplarily, the receiving parameter information can be carried in a second receiving message, the second receiving message comprising at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter in one-to-one correspondence. A value of each receiving function field is used to indicate a value or a value range of the at least one charging receiving parameter corresponding to each receiving function field.

[0019] On this basis, the wireless receiving device can send the receiving standard information to the wireless transmitting device through the first receiving message.

[0020] In a possible implementation, after determining whether the wireless transmitting device and the wireless receiving device can interoperate, the wireless transmitting device can further send first indication information to the wireless receiving device, the first indication information indicating whether the wireless transmitting device and the wireless receiving device can interoperate. That is, the wireless transmitting device can inform the wireless receiving device of the interoperation judgment result through the first indication information.

[0021] Generally, the interoperation judgment can be performed before starting the wireless charging. After the wireless transmitting device determines whether the wireless transmitting device and the wireless receiving device can interoperate, when the wireless transmitting device and the wireless receiving device can interoperate, the wireless transmitting device can further perform the wireless charging with the wireless receiving device.

[0022] In a second aspect, the embodiments of the present application provide an interoperability determination method, which can be applied to a management server, and the management server can control at least one wireless transmitting device. The technical effects of the corresponding solutions in the second aspect can be referred to the technical effects of the corresponding solutions in the first aspect, and the repeated parts will not be described in detail. For example, the interoperability determination method mainly includes: the management server receives receiving standard information and receiving parameter information from a wireless receiving device. The receiving standard information can indicate a target charging standard of the wireless receiving device, and the receiving parameter information can indicate a charging receiving parameter in the wireless receiving device that meets the target charging standard. The management server can determine at least one first wireless transmitting device that supports the target charging standard from the at least one wireless transmitting device according to the receiving standard information. The management server further acquires charging transmitting parameters in the at least one first wireless transmitting device that meet the target charging standard. Then, the management server determines a target transmitting device from the at least one first wireless transmitting device according to the receiving parameter information, and the charging transmitting parameters in the target transmitting device that meet the target charging standard match the charging receiving parameters.

[0023] For example, the charging transmitting parameters include at least one of the following parameters in the wireless transmitting device: an output power level, a compensation network structure, a self-induction range of a transmitting coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmitting coil; and / or the charging receiving parameters include at least one of the following parameters in the wireless receiving device: a receiving power level, a compensation network structure, a ground clearance type of a receiving coil, a self-induction range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0024] By using the interoperability determination method, the management server can determine the target wireless transmitting device that can interoperate with the wireless receiving device from the at least one wireless transmitting device controlled by the management server. Thus, the user of the wireless receiving device can directly use the wireless transmitting device for wireless charging, and the user does not need to find the wireless transmitting device that can interoperate with the wireless receiving device by himself / herself, which is beneficial to improve the user experience.

[0025] In a possible implementation, after determining the target transmitting device from the at least one first wireless transmitting device, the management server can further send second indication information to the wireless receiving device, and the second indication information is used to instruct the wireless receiving device to perform wireless charging with the target transmitting device.

[0026] Exemplarily, the receiving standard information can be carried in a first receiving message, the first receiving message comprising at least one receiving standard field, and the at least one receiving standard field corresponding to at least one charging standard in one-to-one correspondence. A value of each receiving standard field can indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0027] Exemplarily, the receiving parameter information can be carried in a second receiving message, the second receiving message comprising at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter. A value of each receiving function field can indicate a value or a value range of the charging receiving parameter corresponding to each receiving function field.

[0028] In a third aspect, an embodiment of the present application provides an interoperability determination method, which can be applied to a wireless receiving device. The technical effects of the corresponding solutions in the second aspect can be referred to the technical effects of the corresponding solutions in the first aspect, and the repeated parts will not be described in detail. Exemplarily, the interoperability determination method mainly comprises: the wireless receiving device receives transmitting standard information and transmitting parameter information from a wireless transmitting device, the transmitting standard information can indicate at least one charging standard supported by the wireless transmitting device, and the transmitting parameter information can indicate charging transmitting parameters corresponding to the at least one charging standard in the wireless transmitting device. When the wireless receiving device determines that a target charging standard of the at least one charging standard includes the wireless receiving device according to the transmitting standard information, the wireless receiving device acquires charging transmitting parameters conforming to the target charging standard according to the transmitting parameter information. The wireless receiving device can further determine whether the wireless transmitting device and the wireless receiving device can interoperate according to the charging transmitting parameters conforming to the target charging standard and charging receiving parameters conforming to the target charging standard in the wireless receiving device.

[0029] Exemplarily, the charging transmitting parameters comprise at least one of the following parameters in the wireless transmitting device: an output power level, a compensation network structure, a self-induction range of a transmitting coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmitting coil; and / or the charging receiving parameters comprise at least one of the following parameters in the wireless receiving device: a receiving power level, a compensation network structure, a ground clearance type of a receiving coil, a self-induction range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0030] The interoperation determination method provided in the embodiments of the present application can be used to determine whether the wireless transmitting device and the wireless receiving device can interoperate. The wireless receiving device can determine whether the wireless receiving device and the wireless transmitting device can interoperate before starting charging with the wireless transmitting device. If the wireless receiving device and the wireless transmitting device cannot interoperate, the wireless receiving device can not perform wireless charging with the wireless receiving device, thereby protecting the safety of the wireless transmitting device and the wireless receiving device, and reducing the inconvenience to the user caused by the fact that the wireless transmitting device and the wireless receiving device cannot interoperate. For example, if the wireless receiving device is an electric vehicle and the wireless transmitting device is a wireless charging station, the electric vehicle can determine whether the electric vehicle and the wireless charging station can interoperate before driving to the wireless charging station. If the electric vehicle and the wireless charging station cannot interoperate, the electric vehicle can immediately select another wireless charging station. Therefore, the use experience of the user can be improved.

[0031] It can be understood that when the wireless receiving device determines that the target charging standard of the wireless receiving device is not included in the at least one charging standard according to the transmission standard information, the wireless receiving device can directly determine that the wireless transmitting device and the wireless receiving device cannot interoperate.

[0032] For example, when the wireless receiving device determines whether the wireless transmitting device and the wireless receiving device can interoperate according to the charging transmission parameter conforming to the target charging standard and the charging receiving parameter conforming to the target charging standard in the wireless receiving device, the wireless receiving device can determine that the wireless transmitting device and the wireless receiving device can interoperate when the charging transmission parameter conforming to the target charging standard and the charging receiving parameter conforming to the target charging standard match, and determine that the wireless transmitting device and the wireless receiving device cannot interoperate when the charging transmission parameter conforming to the target charging standard and the charging receiving parameter conforming to the target charging standard do not match.

[0033] For example, the transmission standard information can be carried in a first transmission message, the first transmission message includes at least one transmission standard field, and the at least one transmission standard field is in one-to-one correspondence with at least one charging standard. The value of each transmission standard field is used to indicate whether the wireless transmitting device supports the charging standard corresponding to each transmission standard field.

[0034] For example, the transmission parameter information can be carried in a second transmission message, the second transmission message includes at least one transmission function field, and the at least one transmission function field is in one-to-one correspondence with at least one charging transmission parameter. The value of each transmission function field is used to indicate the value or value range of the charging transmission parameter corresponding to each transmission function field.

[0035] In a possible implementation, after determining whether the wireless transmitting device and the wireless receiving device can interoperate, the wireless receiving device can further send third indication information to the wireless transmitting device, where the third indication information can indicate whether the wireless transmitting device and the wireless receiving device can interoperate. That is, the wireless receiving device can inform the wireless transmitting device of the interoperability determination result through the third indication information.

[0036] After the wireless receiving device determines whether the wireless transmitting device and the wireless receiving device can interoperate, when the wireless transmitting device and the wireless receiving device can interoperate, the wireless receiving device can perform wireless charging with the wireless transmitting device.

[0037] In a fourth aspect, an embodiment of the present application provides a device, which can be a wireless transmitting device or a semiconductor chip in the wireless transmitting device. The device has the functions of implementing the first aspect or various possible implementation manners of the first aspect. The functions can be implemented through hardware or by executing corresponding software through hardware. The hardware or software includes one or more units or modules corresponding to the above functions.

[0038] For example, the device includes a transmitting control module and a transmitting communication module. The transmitting control module can execute computer-executed instructions to make the device perform the method in the first aspect or any one of the implementation manners of the first aspect through the transmitting communication module.

[0039] In a fifth aspect, an embodiment of the present application provides a device, which can be a management server or a semiconductor chip in the management server. The device has the functions of implementing the second aspect or various possible implementation manners of the second aspect. The functions can be implemented through hardware or by executing corresponding software through hardware. The hardware or software includes one or more units or modules corresponding to the above functions.

[0040] For example, the device includes a processor and a transceiver. The processor can execute computer-executed instructions to make the device perform the method in the second aspect or any one of the implementation manners of the second aspect through the transceiver.

[0062] The embodiments of the present application will be described in detail below with reference to the drawings.

[0063] Wireless charging is likely to become the mainstream of future electric vehicle charging. Figure 1 An example shows a common wireless charging scenario. As Figure 1As shown, the wireless charging system 00 mainly includes an electric vehicle 10, a wireless charging station 20 and a power source 30. The wireless charging station 20 can be a fixed wireless charging station, a fixed wireless charging parking space, a wireless charging road, etc. The wireless charging station 102 can be set on the ground or buried in the ground (such as Figure 1 During wireless charging, the electric vehicle 10 is located above the wireless charging station 20. The wireless charging station 20 can receive power from the power source 30 and provide the power to the electric vehicle in the form of wireless energy.

[0064] Next, the electric vehicle 10 , the wireless charging station 20 , and the power source 30 are further exemplarily described.

[0065] 1. Electric Vehicles 10

[0066] like Figure 1 As shown, the electric vehicle 10 mainly includes a power receiving module 101, a receiving control module 102, a receiving conversion module 103, an energy storage module 104, and a receiving communication module 105. The receiving control module 102 is connected to the receiving communication module 105 and the receiving conversion module 103 respectively. The receiving conversion module 103 is also connected to the power receiving module 101 and the energy storage module 104 respectively.

[0067] The power receiving module 101 is mainly used to receive the wireless energy transmitted by the wireless charging station 20. For example, Figure 2 As shown, the power receiving module 101 mainly includes a receiving coil Ls and a compensation network 1. The receiving coil Ls is mainly used for electromagnetic coupling with the transmitting coil Lp in the power transmitting module 201, so as to receive the wireless energy transmitted by the power transmitting module 201.

[0068] The compensation network 1 can adjust the input equivalent impedance of the receiving conversion module 103 so that the receiving conversion module 103 can work safely and efficiently. In general, the compensation network 1 can be composed of one or more capacitors, and / or one or more inductors. There are many possible network structures for the compensation network 1. For example, the compensation network 1 includes a capacitor, which is connected in series with the receiving coil Ls (S type), or the capacitor is connected in series with the receiving coil Ls (P type). For another example, the compensation network 1 includes two inductors and one capacitor (LCL type). For another example, the compensation network 1 can also include two capacitors and one inductor (LCC type), etc., which will not be listed one by one in the embodiments of the present application.

[0069] The receiving control module 102 can be an electronic control unit (ECU), a processor, a microprocessor, a controller, etc. in the electric vehicle 10, for example, can be a general central processing unit (CPU), a general processor, a digital signal processing (DSP), an application specific integrated circuits (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, transistor logic devices, hardware components or any combination thereof.

[0070] The receiving control module 102 can implement or execute various exemplary logic blocks, modules and circuits described in connection with the disclosure. The receiving control module 102 can also be a combination of implementing computing functions, such as including one or more microprocessor combinations, combinations of DSP and microprocessor, etc. The receiving control module 102 can adjust the input and output voltage, input and output current and frequency conversion parameters of the receiving conversion module 103 according to the actual receiving power requirement of wireless charging.

[0071] The receiving conversion module 103 can convert the wireless power received by the power receiving module 101 into direct current power required for charging the energy storage module 104 under the control of the receiving control module 102. Generally, the receiving conversion module 103 can include a rectifier circuit and / or a direct current conversion circuit. The rectifier circuit can convert the alternating current power received by the power receiving module 101 into direct current power, and the direct current conversion circuit can adjust the voltage of the direct current power output by the rectifier circuit when the rectifier circuit has no adjustment capability, thereby outputting the charging power required by the energy storage module 104.

[0072] Generally speaking, the electric vehicle 10 may further include a receiving communication module 105, which may be used to implement communication between the electric vehicle 10 and the wireless charging station 20. Exemplarily, the communication methods that the receiving communication module 105 may employ include, but are not limited to, any one or more combinations of Bluetooth, Wireless-Fidelity (WiFi), Zigbee, Radio Frequency Identification (RFID), Long Range (Lora) wireless technology, and Near Field Communication (NFC). In some scenarios, the receiving communication module 105 may also communicate with a smart terminal of a user of the electric vehicle 10, enabling the user to achieve remote control through the communication function.

[0073] 2. Wireless Charging Station 20

[0074] like Figure 1 As shown, the wireless charging station 20 mainly includes a power transmission module 201, a transmission control module 202, a transmission conversion module 203, and a transmission communication module 204. The transmission control module 202 is connected to the transmission conversion module 203 and the transmission communication module 204 respectively. The transmission conversion module 203 is also connected to the power transmission module 201 and the power supply 30 respectively.

[0075] The power transmission module 201 is mainly used to transmit wireless energy to the electric vehicle 10. For example, Figure 2 As shown, the power transmitting module 201 mainly includes a transmitting coil Lp and a supplementary network 2. The transmitting coil Lp is mainly used for electromagnetic coupling with the receiving coil Ls in the power receiving module 101, so as to transmit wireless energy to the power receiving module 101.

[0076] Compensation network 2 can adjust the output equivalent impedance of transmission conversion module 203, so that the power switch tube in transmission conversion module 203 can achieve soft switching. Similar to compensation network 1, compensation network 2 also has multiple possible network structures, which will not be listed one by one.

[0077] Generally, the network structure of the compensation network 1 is adapted to the network structure of the compensation network 2. Common network structure combinations include: series-series type (S-S type), parallel-parallel type (P-P type), series-parallel type (S-P type), parallel-series type (P-S type), inductance-capacitance-inductance-inductance-capacitance-inductance type (LCL-LCL type), inductance-capacitance-inductance-parallel type (LCL-P type), inductance-capacitance-capacitance-inductance-capacitance-capacitance type (LCC-LCC type), and the like. Among them, the left side of "-" represents the network structure of the compensation network 2, and the right side of "-" represents the network structure of the compensation network 1.

[0078] The transmission control module 202 can be a control component such as an electronic control unit (ECU), a processor, a microprocessor, a controller, etc. in the wireless charging station 20, which can be a general central processing unit (CPU), a general processor, a digital signal processing (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a transistor logic device, a hardware component, or any combination thereof.

[0079] The transmission control module 202 can implement or execute various exemplary logic blocks, modules and circuits described in combination with the disclosure. The reception control module 102 can also be a combination of computing functions, such as including one or more microprocessor combinations, combinations of DSP and microprocessor, and the like. The transmission control module 202 can adjust the input and output voltage, input and output current, and frequency conversion parameters of the transmission conversion circuit 203 according to the actual transmission power requirement of the wireless charging, and control the output voltage and operating current of the transmission coil Ls in the power transmission module 201.

[0080] The transmission conversion module 203 can be connected with the power supply 30 to obtain electrical energy from the power supply 30, and under the control of the transmission control module 202, convert the electrical energy obtained from the power supply 30 into alternating current energy, and provide the alternating current energy to the power transmission module 201. Among them, the electrical energy obtained from the power supply 30 can be alternating current energy or direct current energy, and the specific implementation of the transmission conversion module 203 also has multiple possible ways.

[0081] Specifically, when the power output by the power supply 30 is alternating current power, the transmission conversion module 203 can include a power factor correction circuit and an inverter circuit. The power factor correction circuit can ensure that the phase of the input current of the transmission conversion module 203 is consistent with the voltage phase of the power supply 30, reduce the harmonic content of the system, and improve the power factor value to reduce pollution to the power supply 30. The transmission control module 202 can also raise or lower the output voltage of the power factor correction circuit according to the needs of the subsequent power transmission module 201. The inverter circuit can convert the output voltage of the power factor correction circuit into an alternating voltage and provide it to the power transmission module 201.

[0082] When the power output by the power supply 30 is direct current power, the transmission conversion module 203 can include an inverter circuit, which will not be described in detail.

[0083] The specific implementation of the transmission communication module 204 is similar to that of the reception communication module 105, and will not be described in detail.

[0084] It should be noted that the above modules are only examples, and in addition to the above modules, the wireless charging station 20 can also include other modules. For example, the wireless charging station 20 can also include an authentication management module, which can perform permission authentication and management on the electric vehicle 10. For example, the authentication management module can authenticate whether the electric vehicle 10 has permission to use the wireless charging station 20 for charging.

[0085] For another example, the wireless charging station 20 can also include a storage module, which can store data generated during wireless charging, interactive authentication data (such as interactive authentication information), and permission management data (such as permission management information). The interactive authentication data and the permission management data can be factory-set or user-set, and the embodiments of the present application do not make specific limitations.

[0086] 3, the power supply 30

[0087] The power supply 30 can be a device or equipment capable of outputting power, such as a power grid or a high-power battery. In the case of the power supply 30 as a high-power battery, the power supply 30 can be located outside the wireless charging station 20 or integrated inside the wireless charging station 20, and the embodiments of the present application do not make many limitations.

[0088] From the above introduction of the wireless charging system 00, it can be seen that wireless charging depends on the coordination between the electric vehicle 10 and the wireless charging station 20, and the coordination between the electric vehicle 10 and the wireless charging station 20 can also be called interoperation. That is, only in the case of interoperation between the electric vehicle 10 and the wireless charging station 20, safe and efficient wireless charging can be achieved.

[0089] Generally, the electric vehicle 10 and the wireless charging station 20 can be interoperable only when they support the same charging standard. The charging standard specifies various aspects of wireless charging. For example, in the Chinese national standard scheme, the off-ground clearance of the receiving coil is defined in the Chinese national standard scheme “Electric Vehicle Wireless Charging System Part 3: Special Requirements”, as shown in Table 1 below:

[0090] Table 1

[0091] Type Ground clearance (mm) Z1 100～150 Z2 140～210 Z3 170～250 Z4 ≥250

[0092] As shown in Table 1, the off-ground clearance of the receiving coil is divided into four types (Type Z1 to Type Z4) in the Chinese national standard scheme, each type corresponding to a different off-ground clearance range.

[0093] The input power level of the power transmitting device 201 is also specified in the Chinese national standard scheme “Electric Vehicle Wireless Charging System Part 1: General Requirements”. As shown in Table 2 below:

[0094] Table 2

[0095]

[0096] As shown in Table 2, the input power of the power transmitting device 201 is divided into seven levels in the Chinese national standard scheme, each level corresponding to a different power range.

[0097] During wireless charging, the receiving coil in the power receiving module 101 needs to be aligned as much as possible with the transmitting coil in the power transmitting module 201. However, in actual operation, it is difficult for the transmitting coil and the receiving coil to be completely aligned, so the Chinese national standard scheme also specifies the allowable offset range: the offset range in the X direction (the direction of the front and rear of the electric vehicle 10) is ±75 mm, and the offset range in the Y direction (the direction of the two side doors of the electric vehicle 10) is ±100 mm.

[0098] As can be seen, various aspects of the electric vehicle 10 and the wireless charging station 20 are specified in the charging standard. The manufacturers of the electric vehicle 10 and the wireless charging station 20 can both produce the electric vehicle 10 and the wireless charging station 20 according to the specifications of the charging standard.

[0099] However, there is no unified standard in the current wireless charging field. For example, in addition to the above-mentioned Chinese standard scheme, the current common charging standards also include the IEC international standard scheme, the ISO international standard scheme, the American national standard recommended scheme, and the like. In different charging standards, different types of charging parameters are specified, or different values or value ranges of the same charging parameter are specified. For example, for different charging standards, there may be differences in the compensation network structure, the operating current range of the transmitting coil, the adjustment mode of the charging power, the receiving coil ground clearance, the power level division, the offset range, and the like.

[0100] For the manufacturer of the electric vehicle 10, the electric vehicle 10 is often manufactured according to one of the charging standards. In order to be compatible with more types of electric vehicles 10, the current wireless charging station 20 can support more and more charging standards. However, even if the wireless charging station 20 can be compatible with multiple charging standards, it cannot be guaranteed that the wireless charging station 20 and all types of electric vehicles 10 can interoperate.

[0101] If the wireless charging station 20 cannot interoperate with the electric vehicle 10, the wireless charging station 20 can not be able to charge the electric vehicle 10, and even can damage the electric vehicle 10 or the wireless charging station 20. Especially when the wireless charging station 20 is a public wireless charging station, the electric vehicle 10 using the wireless charging station 20 for charging can support any type of charging standard. In this case, how to guarantee the safety of the wireless charging station 20 and the electric vehicle 10 and improve the user experience is a problem that needs to be solved in the wireless charging field.

[0102] Therefore, the embodiments of the present application provide an interoperability determination method, which can be applied to a wireless transmitting device or a wireless receiving device. The wireless transmitting device can be a wireless charging station 20, or a chip or module set for wireless charging in the wireless charging station 20. The wireless receiving device can be an electric vehicle 10, an electric unmanned aerial vehicle, or the like, or a chip or module set for wireless charging in the electric vehicle 10, the electric unmanned aerial vehicle, or the like.

[0103] Before wireless charging between the wireless transmitting device and the wireless receiving device, interoperability determination is performed. After it is determined that interoperability can be achieved, wireless charging is performed, thereby facilitating the safety of the wireless transmitting device and the wireless receiving device and improving the user experience.

[0104] For ease of understanding, the embodiments of the present application will be described below with the wireless transmitting device being a wireless charging station 20 and the wireless receiving device being an electric vehicle 10 as an example, and subsequent descriptions will not be repeated.

[0105] Next, the interoperability determination method provided by the embodiments of the present application is further exemplarily described through the following examples.

[0106] Example One: the wireless charging station 20 determines interoperability

[0107] Figure 3 An exemplary flowchart of the interoperability determination method provided by the embodiments of the present application is shown. As shown in the figure, the interoperability determination method mainly includes the following steps: Figure 3

[0108] S301: The wireless charging station 20 receives the receiving standard information and the receiving parameter information from the electric vehicle 10. The receiving standard information can indicate the target charging standard of the electric vehicle 10, which can be the charging standard supported by the electric vehicle 10. The receiving parameter information can indicate the charging receiving parameters in the electric vehicle 10 that meet the provisions of the target charging standard.

[0109] Exemplarily, the receiving standard information and the receiving parameter information can be directly sent by the electric vehicle 10 to the wireless charging station 20, or sent by the electric vehicle 10 to other devices and then forwarded to the wireless charging station 20 by the other devices, and the embodiments of the present application do not make many restrictions on this.

[0110] The charging receiving parameters can be understood as the specific implementation of the various charging parameters related to wireless charging in the electric vehicle 10 as specified in the target charging standard. For example, if the type of the ground clearance of the transmitting coil is specified in the charging standard as shown in Table 1, the charging receiving parameters of the electric vehicle 10 can include the type of the ground clearance of the transmitting coil, and the value of the type of the ground clearance of the transmitting coil can indicate any one of Z1 to Z4.

[0111] S302: When the wireless charging station 20 determines that the target charging standard is supported by the wireless charging station 20 according to the receiving standard information, the wireless charging station 20 obtains the charging transmitting parameters in the wireless charging station 20 that meet the provisions of the target charging standard.

[0112] Specifically, the wireless charging station 20 can support multiple charging standards, and the wireless charging station 20 can determine whether the target charging standard is included in the multiple charging standards supported by the wireless charging station 20 according to the receiving standard information. For example, the wireless charging station 20 can support the Chinese national standard recommended scheme, the IEC international standard scheme and the American national standard recommended scheme, and if the target charging standard supported by the electric vehicle 10 is any one of the above three standards, the wireless charging station 20 can continue to perform S302.

[0113] ​As mentioned above, different charging standards specify different types of charging parameters, or different values or value ranges for the same charging parameter. Therefore, after determining the target charging standard, the wireless charging station 20 needs to obtain the charging transmission parameters in the wireless charging station 20 that meet the requirements of the target charging standard. The charging transmission parameters can be understood as the specific implementation of the various charging parameters related to wireless charging specified by the target charging standard in the wireless charging station 20.

[0114] Taking the current Chinese national standard scheme as an example, in order to realize the interoperability between the electric vehicle 10 and the wireless charging station 20, the charging transmission parameters can include one or more of the following parameters in the wireless charging station 20: output power level, compensation network structure, self-inductance range of the transmission coil, coupling coefficient range, operating frequency range, maximum adjustable current of the transmission coil, and the like. The embodiments of the present application will not be enumerated one by one.

[0115] It can be understood that if the target charging standard is not included in the various charging standards supported by the wireless charging station 20, it can be directly determined that the wireless charging station 20 and the electric vehicle 10 cannot interoperate.

[0116] It should be noted that different charging standards specify different charging modes (equivalent). For example, charging mode 1 corresponds to the Chinese national standard scheme, and charging mode 2 corresponds to the American national standard recommended scheme. That is, if the electric vehicle 10 supports the Chinese national standard scheme, the charging mode of the electric vehicle 10 is charging mode 1. If the electric vehicle 10 supports the American national standard recommended scheme, the charging mode of the electric vehicle 10 is charging mode 2.

[0117] Therefore, the received standard information in the embodiments of the present application can also be understood as indicating the charging mode of the electric vehicle 10. In this case, the wireless charging station 20 can also determine whether to support the target charging standard by determining whether to support the charging mode of the electric vehicle 10. It can be understood that the charging mode and the charging standard have the same effect in the embodiments of the present application, both of which are to ensure the rationality of subsequent parameter matching, i.e. the matching between charging parameters specified by different charging standards and the matching between charging parameters in different charging modes, which is meaningless for interoperability determination. Therefore, the charging mode should be understood as a specific implementation of the charging standard and should also be included in the embodiments of the present application. In order to facilitate description, the charging standard will be taken as an example for description.

[0118] S303: The wireless charging station 20 determines whether the wireless charging station 20 and the electric vehicle 10 can interoperate according to the charging transmission parameters and the charging reception parameters that meet the requirements of the target charging standard.

[0119] It can be understood that, since the charging transmission parameter and the charging receiving parameter are both parameters conforming to the target charging standard, the charging transmission parameter and the charging receiving parameter are often corresponding. For example, the charging transmission parameter can include the output power level of the wireless charging station 20, and the charging receiving parameter can include the receiving power level of the electric vehicle 10. The charging transmission parameter can include the maximum adjustable current of the transmitting coil in the wireless charging station 20, and the charging receiving parameter can include the maximum working current of the electric vehicle 10, and the like. The embodiments of the present application will not be enumerated one by one.

[0120] For example, the wireless charging station 20 can determine whether the wireless charging station 20 and the electric vehicle 10 can interoperate according to whether the charging transmission parameter and the charging receiving parameter match. Specifically, when the charging transmission parameter and the charging receiving parameter match, the wireless charging station 20 can determine that the wireless charging station 20 and the electric vehicle 10 can interoperate. When the charging transmission parameter and the charging receiving parameter do not match, it is determined that the wireless charging station 20 and the electric vehicle 10 cannot interoperate.

[0121] It can be understood that the charging transmission parameter and the charging receiving parameter match means that the wireless charging station 20 can work safely and efficiently under the condition of supporting the wireless receiving parameter, and at the same time, the electric vehicle 10 can also work safely and efficiently under the condition of supporting the wireless transmission parameter. If the wireless charging station 20 cannot work safely and efficiently under the condition of supporting the wireless receiving parameter, or the electric vehicle 10 cannot work safely and efficiently under the condition of supporting the wireless transmission parameter, it can be considered that the charging transmission parameter and the charging receiving parameter do not match.

[0122] For example, if the receiving power level of the electric vehicle 10 is MF-WPT5 and the transmitting power level of the wireless charging station 20 is MF-WTP1, it can be considered that the transmitting power of the wireless charging station 20 and the receiving power of the electric vehicle 10 do not match, and the electric vehicle 10 and the wireless charging station 20 cannot interoperate.

[0123] It should be pointed out that the charging transmission parameter and the charging receiving parameter often include multiple parameters. In the case that all the charging transmission parameters and the corresponding charging receiving parameters can match, it can be determined that the electric vehicle 10 and the wireless charging station 20 can interoperate. If there is at least one charging transmission parameter and the corresponding charging receiving parameter that cannot match, it can be determined that the electric vehicle 10 and the wireless charging station 20 cannot interoperate.

[0124] Next, the interoperability method provided by the embodiments of the present application will be further exemplarily described by the flow chart shown in Figure 5 As shown in Figure 5 , the main steps include the following steps:

[0125] S501: The electric vehicle 10 sends reception standard information and reception parameter information to the wireless charging station 20. The reception standard information may indicate a target charging standard supported by the electric vehicle 10, and the reception parameter information may indicate charging parameters in the electric vehicle 10 that comply with the target charging standard.

[0126] It is understood that before S501, the electric vehicle 10 and the wireless charging station 20 may also perform a communication handshake to establish a wireless communication link. Specific implementations may refer to existing technologies and will not be described in detail.

[0127] S502: The wireless charging station 20 determines whether it supports the target charging standard. If so, it executes S503; if not, it executes S506.

[0128] S503: The wireless charging station 20 obtains charging transmission parameters corresponding to the target charging standard in the wireless charging station 20 .

[0129] S504: The wireless charging station 20 determines whether the charging transmission parameters and the charging reception parameters match. If so, the process proceeds to S505; if not, the process proceeds to S507.

[0130] S505 : Determine whether the electric vehicle 10 and the wireless charging station 20 are interoperable.

[0131] S506 : Determine that the electric vehicle 10 and the wireless charging station 20 are not capable of interoperating with each other.

[0132] S507 : Determine that the electric vehicle 10 and the wireless charging station 20 are not capable of interoperating with each other.

[0133] In one possible implementation, Figure 5 As shown, after determining whether the electric vehicle 10 and the wireless charging station 20 are interoperable, the wireless charging station 20 may continue to execute S508: sending first indication information to the electric vehicle 10, where the first indication information may indicate to the electric vehicle 10 whether the wireless charging station 20 and the electric vehicle 10 are interoperable.

[0134] It should be understood that when the electric vehicle 10 sends the reception standard information and the reception parameter information to the wireless charging station 20, the electric vehicle 10 does not need to be parked above the wireless charging station 20. For example, the electric vehicle 10 can send the reception standard information and the reception parameter information to the wireless charging station 20 while driving toward the wireless charging station 20, or before driving toward the wireless charging station 20.

[0135] If the electric vehicle 10 and the wireless charging station 20 are not interoperable, the electric vehicle 10 can receive the first indication information before reaching the wireless charging station 20, and the user can immediately find other available wireless charging stations, thereby improving the user experience.

[0136] If the electric vehicle 10 and the wireless charging station 20 can interoperate, the wireless charging station 20 can perform wireless charging with the electric vehicle 10. The specific process of wireless charging can refer to the conventional wireless charging scheme. Generally, it mainly includes the following steps:

[0137] Step one: position alignment. The electric vehicle 10 judges whether the offset distance between the transmitting coil and the receiving coil is within the offset range that can be charged. If it is not within the offset range that can be charged, continue to adjust the position until the offset distance between the transmitting coil and the receiving coil falls within the offset range that can be charged. If it is within the offset range that can be charged, the electric vehicle 10 continues to detect the coupling coefficient. It can be understood that this step can also be implemented by the wireless charging station 20, which will not be described again.

[0138] Step two: detecting the coupling coefficient. The electric vehicle 10 detects the coupling coefficient between the transmitting coil and the receiving coil, and if the coupling coefficient is within the range that the wireless charging station 20 and the electric vehicle 10 can normally work, it sends a charging request to the wireless charging station 20, and if the coupling coefficient is not within the range that the wireless charging station 20 and the electric vehicle 10 can normally work, the electric vehicle 10 continues to adjust the position until the coupling coefficient falls within the range that the wireless charging station 20 and the electric vehicle 10 can normally work.

[0139] Step three: the electric vehicle 10 sends a charging request to the wireless charging station 20, and the wireless charging station 20 starts to output wireless energy in response to the charging request, thereby starting charging.

[0140] It should be understood that the above steps one to three are only a brief description, and the specific implementation can refer to the prior art.

[0141] Next, the specific implementation of receiving standard information and receiving parameter information is further exemplarily described.

[0142] Receiving standard information

[0143] Exemplarily, the receiving standard information can be carried in a first receiving message, the first receiving message includes at least one receiving standard field, and the at least one receiving standard field corresponds to at least one charging standard one by one. For example Figure 4 As shown, the first receiving message includes at least four receiving standard fields: field A, field B, field C and field D. The correspondence between the four receiving standard fields and the charging standards is shown in Table Four as follows:

[0144] Table Four

[0145] Receiving standard field Charging standard Field A Chinese national standard recommended scheme Field B IEC international standard scheme Field C ISO international standard scheme Field D American national standard recommended scheme

[0146] As shown in Table Four, in the four receiving standard fields of the first received message, field A corresponds to the Chinese national standard recommended scheme, field B corresponds to the IEC international standard scheme, field C corresponds to the ISO international standard scheme, and field D corresponds to the American national standard recommended scheme.

[0147] In the first received message, the value of each receiving standard field can indicate whether the charging standard corresponding to each receiving standard field is the target charging standard of the electric vehicle 10. For example, the format of the first received message can be as shown in Table Five:

[0148] Table Five

[0149]

[0150]

[0151] As shown in Table Five, the first received message includes two bytes. In the first received message, field A starts from the first bit and occupies two bits. When the value of field A is 00, it means that the Chinese national standard recommended scheme is not the target charging standard, and when the value of field A is 01, it means that the Chinese national standard recommended scheme is the target charging standard.

[0152] Field B starts from the third bit and occupies two bits. When the value of field B is 00, it means that the IEC international standard scheme is not the target charging standard, and when the value of field B is 01, it means that the IEC international standard scheme is the target charging standard.

[0153] Field C starts from the fifth bit and occupies two bits. When the value of field C is 00, it means that the ISO international standard scheme is not the target charging standard, and when the value of field C is 01, it means that the ISO international standard scheme is the target charging standard.

[0154] Field D starts from the seventh bit and occupies two bits. When the value of field D is 00, it means that the American national standard recommended scheme is not the target charging standard, and when the value of field D is 01, it means that the American national standard recommended scheme is the target charging standard.

[0155] Fields A to D are parameters that must be carried in the first received message, i.e., mandatory parameters. In addition, there are eight bytes as a reserved field, which is an optional parameter. The reserved field starts from byte 9 and occupies eight bytes. It can be understood that the first received message can also include one byte without including the reserved field.

[0156] In addition, the first received message can also carry other information. For example, the first received message can also carry format information to indicate the information format in the first received message. For example, hexadecimal, octal, binary, etc.

[0157] receiving parameter information

[0158] Exemplarily, the receiving parameter information can be carried in a second receiving message, which can be the same as or different from the first receiving message. The embodiments of the present application do not make many limitations on this.

[0159] The at least one receiving function field in the second receiving message corresponds to the at least one charging receiving parameter one by one, wherein the value of each receiving function field can indicate the value or value range of the corresponding charging receiving parameter.

[0160] Exemplarily, as shown in Figure 6 The second receiving message includes nine receiving function fields: field 1 to field 9. The specific format of the second receiving message can be as shown in Table Six:

[0161] Table Six

[0162]

[0163]

[0164]

[0165] As shown in Table Six and Figure 6 The second receiving message includes eight bytes, and the nine receiving function fields in the second receiving message correspond to nine charging receiving parameters respectively. Specifically:

[0166] Field 1 corresponds to the receiving power level of the electric vehicle 10, field 1 occupies the positions of Bit2 to Bit0 in Byte1, and there are eight possible values. Exemplarily, when the value of field 1 is 000, it indicates that the receiving power level of the electric vehicle 10 is MF-WPT1. When the value of field 1 is 001, it indicates that the receiving power level of the electric vehicle 10 is MF-WPT2. When the value of field 1 is 010, it indicates that the receiving power level of the electric vehicle 10 is MF-WPT3. Other possible values can be reserved.

[0167] Field 2 corresponds to the compensation network structure in the electric vehicle 10, field 2 occupies the positions of Bit7 to Bit3 in Byte1, there are 32 possible values. For example, when field 2 takes the value of 00000, it indicates that the compensation network structure of the electric vehicle 10 is LCC type structure. When field 2 takes the value of 00001, it indicates that the compensation network structure of the electric vehicle 10 is series type structure. When field 2 takes the value of 00010, it indicates that the compensation network structure of the electric vehicle 10 is parallel type structure. When field 2 takes the value of 00011, it indicates that the compensation network structure of the electric vehicle 10 is series-parallel type structure. Other possible values can be reserved.

[0168] Field 3 corresponds to the ground clearance of the receiving coil in the electric vehicle 10, field 3 occupies the positions of Bit2 to Bit0 in Byte2, there are 8 possible values. For example, when field 3 takes the value of 000, it indicates that the ground clearance of the receiving coil in the electric vehicle 10 is Z1. When field 3 takes the value of 001, it indicates that the ground clearance of the receiving coil in the electric vehicle 10 is Z2. When field 3 takes the value of 010, it indicates that the ground clearance of the receiving coil in the electric vehicle 10 is Z3. Other possible values can be reserved.

[0169] Field 4 corresponds to the self-inductance range of the transmitting coil supported by the electric vehicle 10, field 4 occupies the positions of Bit7 to Bit3 in Byte2, there are 32 possible values. For example, when field 4 takes the value of 00000, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp1. When field 4 takes the value of 00001, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp2. When field 4 takes the value of 00010, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp3. Other possible values can be reserved.

[0170] The indication format of other fields can be similarly deduced, and will not be described here.

[0171] Example II: Interoperation judgment by management server

[0172] With the popularization of wireless charging technology, it is foreseeable that large-scale wireless charging station clusters will emerge. For example, in a public parking lot, wireless charging stations can be arranged in the area where parking spaces are located. In one possible implementation, as shown in FIG. 2, the wireless charging system can further include a management server 40, which can uniformly control at least one wireless charging station (wireless charging station 20-1 to wireless charging station 20-N, N is an integer greater than or equal to 1). Figure 7

[0173] ​In this case, the management server 40 can also make the interoperability determination to determine the wireless charging station capable of interoperating with the electric vehicle 10 from the at least one wireless charging station controlled by the management server 40 to charge the electric vehicle 10. For example, the management server 40 can make the interoperability determination in the following method flow as shown in the following table. Figure 8 The method flow mainly includes the following steps:

[0174] S801: The management server 40 receives the receiving standard information and the receiving parameter information from the electric vehicle 10. The receiving standard information can indicate the target charging standard of the electric vehicle 10, and the receiving parameter information can indicate the charging receiving parameter in the electric vehicle 10 that meets the provision of the target charging standard. The specific implementation of the receiving standard information and the receiving parameter information can refer to Example 1, and will not be repeated here.

[0175] For example, the receiving standard information and the receiving parameter information can be directly sent by the electric vehicle 10 to the management server 40, or sent by the electric vehicle 10 to other devices and then forwarded to the management server 40, and the embodiments of the present application do not limit this too much.

[0176] S802: The management server 40 determines at least one first wireless charging station supporting the target charging standard from the at least one wireless charging station 20 controlled by the management server 40 according to the receiving standard information.

[0177] For example, the target charging standard is the recommended scheme of the Chinese national standard, and the wireless charging station 20-1 and the wireless charging station 20-2 support the recommended scheme of the Chinese national standard among the wireless charging station 20-1 to the wireless charging station 20-N. Then the management server 40 can determine the wireless charging station 20-1 and the wireless charging station 20-2 as the first wireless charging station.

[0178] S803: The management server 40 respectively acquires the charging transmission parameter of the at least one first wireless charging station meeting the provision of the target charging standard. For example, the wireless charging station 20-1 and the wireless charging station 20-2 are the first wireless charging station in the above example, and the management server 40 can acquire the charging transmission parameter of the wireless charging station 20-1 and the wireless charging station 20-2.

[0179] In a possible implementation, the management server 40 can pre-cache the charging transmission parameter of each wireless charging station under different charging standards. In this case, the management server 40 can directly read the charging transmission parameter of the first wireless charging station from the cache.

[0180] In another possible implementation, the management server 40 can also send query information to the first wireless charging station to instruct the first wireless charging station to report the charging transmission parameter corresponding to the target charging standard.

[0181] It can be understood that if there is no first wireless charging station in the wireless charging stations 20-1 to 20-N that can support the target wireless charging standard, the management server 40 can directly determine that the electric vehicle 10 cannot be charged.

[0182] S804: The management server 40 determines a target wireless charging station from the at least one first wireless charging station 20 according to the received parameter information. The target wireless charging station can be a first wireless charging station whose charging transmission parameters can match the charging receiving parameters of the electric vehicle 10. For example, in the above example, if the charging transmission parameters of the wireless charging station 20-1 can match the charging receiving parameters of the electric vehicle 10, the management server 40 can determine the wireless charging station 20-1 as the target wireless charging station.

[0183] In a possible implementation, after determining the target wireless charging station, the management server 40 can further perform S805: sending second indication information to the electric vehicle 10, which can instruct the electric vehicle 10 to perform wireless charging with the target transmission device. For example, the wireless charging station 20-1 is the target wireless charging station, and the management server 40 can instruct the electric vehicle 10 to perform wireless charging with the wireless charging station 20-1 through the second indication information. After receiving the second indication information, the electric vehicle 10 can be parked above the wireless charging station 20-1, so as to perform wireless charging with the wireless charging station 20-1.

[0184] It can be understood that the management server 40 can also send fourth indication information (S806) to the target wireless charging station, which can instruct the target wireless charging station to perform wireless charging with the electric vehicle 10. For example, the wireless charging station 20-1 is the target wireless charging station, and the management server 40 can send the fourth indication information to the wireless charging station 20-1, which can include the identification information of the electric vehicle 10, so that after the electric vehicle 10 is parked above the wireless charging station 20-1, the wireless charging station 20-1 can perform wireless charging with the electric vehicle 10.

[0185] The specific process of wireless charging between the electric vehicle 10 and the wireless charging station 20-1 can refer to the prior art, and will not be described here.

[0186] Example Three: Management Server 40 and First Wireless Charging Device Cooperate to Determine Interoperability

[0187] In the embodiments of the present application, the management server 40 can also determine the first wireless charging station, and the first wireless charging station can determine whether it can be interoperable. For example, as shown in FIG. 8, the main steps include the following steps: Figure 9

[0188] ​S901: The electric vehicle 10 sends the receiving standard information to the management server 40. The specific implementation manner of the receiving standard information can refer to Example One, and details are not described herein again.

[0189] S902: The management server 40 determines at least one first wireless charging station from the wireless charging stations 20-1 to 20-N according to the receiving standard information. The specific implementation manner of S902 can refer to S802, and details are not described herein again.

[0190] S903: The management server 40 sends the fifth indication information to the electric vehicle 10, which can indicate the at least one first wireless charging station to the electric vehicle 10. For example, the wireless charging station 20-1 and the wireless charging station 20-2 are the first wireless charging stations, and the management server 40 can indicate the wireless charging station 20-1 and the wireless charging station 20-2 to the electric vehicle 10 through the fifth indication information.

[0191] S904: The electric vehicle 10 sends the receiving standard information and the receiving parameter information to the at least one first wireless charging station respectively. The specific implementation manners of the receiving standard information and the receiving parameter information can both refer to Example One, and details are not described herein again.

[0192] After S904, each first wireless charging station can perform S503 to S508 as shown in Figure 5 , so as to complete the interoperability judgment. The specific implementation manner can refer to Example One, and details are not described herein again. The electric vehicle 10 can further determine the target wireless charging station which can interoperate with the electric vehicle 10 according to the first indication information fed back by the at least one wireless charging station.

[0193] Example Four: The electric vehicle 10 performs interoperability judgment

[0194] The interoperability judgment method provided in the embodiments of the present application can also be applied to the electric vehicle 10. For example, as shown in Figure 10 , the method mainly includes the following steps:

[0195] S1001: The electric vehicle 10 receives the transmission standard information and the transmission parameter information from the wireless charging station 20. The transmission standard information can indicate at least one charging standard supported by the wireless charging station 20, and the transmission parameter information can indicate the charging transmission parameters corresponding to the at least one charging standard in the wireless charging station 20.

[0196] For example, the transmission standard information and the transmission parameter information can be directly sent to the electric vehicle 10 by the wireless charging station 20, or sent to other devices by the wireless charging station 20 and then forwarded to the electric vehicle 10 by the other devices, and the embodiments of the present application do not limit this too much.

[0197] The transmission of the standard information can be carried in a first transmission message, which includes at least one transmission standard field corresponding to at least one charging standard. The value of each transmission standard field can indicate whether the wireless charging station 20 supports the charging standard corresponding to the transmission standard field. The specific implementation can refer to Figure 4 The above and the content shown in Table 5 will not be repeated.

[0198] The transmission of the parameter information can be carried in a second transmission message, which includes at least one transmission function field corresponding to at least one charging transmission parameter. The value of each transmission function field can indicate the value or value range of the charging transmission parameter corresponding to the transmission function field. The specific implementation of the transmission parameter information can refer to Figure 6 The above and the content shown in Table 6 will not be repeated.

[0199] It should be noted that the difference from Example 1 is that the wireless charging station 20 can support multiple charging standards, so in Example 4, the transmission parameter information sent by the wireless charging station 20 can need to indicate multiple sets of charging transmission parameters, each set of charging transmission parameters corresponding to a charging standard.

[0200] For example, the wireless charging station 20 supports both the Chinese national standard recommended scheme and the IEC international standard scheme, and the transmission parameter information sent by the wireless charging station 20 can indicate both the charging transmission parameters in the wireless charging station 20 that meet the Chinese national standard recommended scheme and the charging transmission parameters in the wireless charging station 20 that meet the IEC international standard scheme.

[0201] S1002: When the electric vehicle 10 determines that the target charging standard of the electric vehicle 10 is included in the at least one charging standard according to the transmission standard information, the electric vehicle 10 acquires the charging transmission parameters that meet the target charging standard according to the transmission parameter information.

[0202] For example, the wireless charging station 20 supports both the Chinese national standard recommended scheme and the IEC international standard scheme, and the target charging standard of the electric vehicle 10 is the Chinese national standard recommended scheme, then the electric vehicle 10 can acquire the charging transmission parameters corresponding to the Chinese national standard recommended scheme in the wireless charging station 20 according to the transmission parameter information.

[0203] It can be understood that if the target charging standard is not included in the charging standard supported by the wireless charging station 20, the electric vehicle 10 can directly determine that the wireless charging station 20 and the electric vehicle 10 cannot be interoperable. For example, the wireless charging station 20 supports the Chinese national standard recommended scheme and the IEC international standard scheme, and the target charging standard of the electric vehicle 10 is the ISO international standard scheme. The electric vehicle 10 can determine that the wireless charging station 20 and the electric vehicle 10 cannot be interoperable.

[0204] S1003: The electric vehicle 10 determines whether the wireless charging station 20 and the electric vehicle 10 can be interoperable according to the charging transmission parameters conforming to the target charging standard and the charging reception parameters conforming to the target charging standard in the electric vehicle 10. The specific implementation of S1003 is similar to S303, and will not be described here.

[0205] In a possible implementation, after determining whether the wireless charging station 20 and the electric vehicle 10 can be interoperable, the electric vehicle 10 can further send third indication information to the wireless charging station 20, which can indicate whether the wireless charging station 20 and the electric vehicle 10 can be interoperable.

[0206] If the wireless charging station 20 and the electric vehicle 10 can be interoperable, the electric vehicle 10 can perform wireless charging with the wireless charging station 20. The specific implementation will not be described here.

[0207] The above mainly introduces the scheme provided by the present application from the perspective of the method embodiment. It can be understood that in order to implement the above functions, the wireless receiving device or the wireless transmitting device or the management server can include the corresponding hardware structure and / or software module for executing each function. Those skilled in the art should easily realize that the units and algorithm steps of each example described in combination with the embodiments disclosed herein can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is implemented in hardware or computer software driven hardware depends on the specific application and design constraints of the technical solution. Professional technicians can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the present application.

[0208] In the case of using integrated units, Figure 11A possible exemplary block diagram of an apparatus involved in embodiments of the present application is shown, which can exist in the form of software. The apparatus 1100 can include a processing unit 1102 and a communication unit 1103. The processing unit 1102 is configured to control and manage actions of the apparatus 1100. The communication unit 1103 is configured to support communication of the apparatus 1100 with other entities. The apparatus 1100 can further include a storage unit 1101 configured to store program codes and data of the apparatus 1100.

[0209] The apparatus 1100 can be a wireless transmitting apparatus (e.g., a wireless charging station) in any of the above embodiments, or can also be a chip or a module set arranged in the wireless transmitting apparatus. The processing unit 1102 can support the apparatus 1100 to perform actions of the wireless transmitting apparatus in the above method examples, and the communication unit 1103 can support communication between the apparatus 1100 and the wireless receiving apparatus.

[0210] Specifically, in one embodiment, the communication unit 1103 can receive receiving standard information and receiving parameter information from the wireless receiving apparatus, the receiving standard information can indicate a target charging standard of the wireless receiving apparatus, and the receiving parameter information can indicate a charging receiving parameter in the wireless receiving apparatus that meets a provision of the target charging standard.

[0211] The processing unit 1102 can acquire a charging transmitting parameter in the apparatus 1100 that meets a provision of the target charging standard when it is determined according to the receiving standard information that the apparatus supports the target charging standard, and determine whether the apparatus 1100 and the wireless receiving apparatus can interoperate according to the charging transmitting parameter that meets the provision of the target charging standard and the charging receiving parameter.

[0212] Exemplarily, the charging transmitting parameter includes at least one of the following parameters in the apparatus 1100: an output power level, a compensation network structure, a self-inductance range of a transmitting coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmitting coil; and / or, the charging receiving parameter includes at least one of the following parameters in the wireless receiving apparatus: a receiving power level, a compensation network structure, a ground clearance type of a receiving coil, a self-inductance range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0213] It can be understood that the processing unit 1102 can also determine that the apparatus and the wireless receiving apparatus cannot interoperate when it is determined according to the receiving standard information that the apparatus does not support the target charging standard.

[0214] For example, the processing unit 1102 can determine whether the device 1100 and the wireless receiving device can interoperate according to the charging transmitting parameters and the charging receiving parameters specified in the target charging standard, and specifically, can determine that the device and the wireless receiving device can interoperate when the charging transmitting parameters and the charging receiving parameters specified in the target charging standard match, and can determine that the device and the wireless receiving device cannot interoperate when the charging transmitting parameters and the charging receiving parameters specified in the target charging standard do not match.

[0215] For example, the receiving standard information can be carried in a first receiving message, the first receiving message including at least one receiving standard field, and the at least one receiving standard field corresponding to at least one charging standard in a one-to-one manner; and a value of each receiving standard field is used to indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0216] For example, the receiving parameter information can be carried in a second receiving message, the second receiving message including at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter in a one-to-one manner; and a value of each receiving function field is used to indicate a value or a value range of the charging receiving parameter corresponding to each receiving function field.

[0217] In a possible implementation, the communication unit 1103 can further send first indication information to the wireless receiving device, the first indication information indicating whether the device and the wireless receiving device can interoperate.

[0218] Generally, after determining that the device and the wireless receiving device can interoperate wirelessly, the device 1100 can perform wireless charging with the wireless receiving device. Therefore, the processing unit 1102 can further control the device to perform wireless charging with the wireless receiving device when the device and the wireless receiving device can interoperate.

[0219] The device 1100 can also be a management server in any of the above embodiments, or can also be a chip or a set of modules arranged in the management server. The processing unit 1102 can support the device 1100 to perform the actions of the management server in the above method examples, and the communication unit 1103 can support the device 1100 to communicate with the wireless transmitting device and the wireless receiving device.

[0220] Specifically, in one embodiment, the communication unit 1103 can receive receiving standard information and receiving parameter information from the wireless receiving device. The receiving standard information can indicate a target charging standard of the wireless receiving device, and the receiving parameter information can indicate charging receiving parameters in the wireless receiving device that comply with the target charging standard. The processing unit 1102 can determine at least one first wireless transmitting device that supports the target charging standard from the at least one wireless transmitting device according to the receiving standard information. The processing unit 1102 can further acquire charging transmitting parameters in the at least one first wireless transmitting device that comply with the target charging standard, respectively. Then, the processing unit 1102 can determine a target transmitting device from the at least one first wireless transmitting device according to the receiving parameter information, in which the charging transmitting parameters that comply with the target charging standard match the charging receiving parameters.

[0221] Exemplary charging transmitting parameters include at least one of the following parameters in the wireless transmitting device: an output power level, a compensation network structure, a self-induction range of a transmitting coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmitting coil; and / or, exemplary charging receiving parameters include at least one of the following parameters in the wireless receiving device: a receiving power level, a compensation network structure, a ground clearance type of a receiving coil, a self-induction range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0222] In one possible implementation, after determining the target transmitting device from the at least one first wireless transmitting device, the communication unit 1103 can further send second indication information to the wireless receiving device, the second indication information being used to instruct the wireless receiving device to perform wireless charging with the target transmitting device.

[0223] Exemplarily, the receiving standard information can be carried in a first receiving message, the first receiving message including at least one receiving standard field, and the at least one receiving standard field corresponding to at least one charging standard one by one. The value of each receiving standard field can indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0224] Exemplarily, the receiving parameter information can be carried in a second receiving message, the second receiving message including at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter. The value of each receiving function field can indicate the value or value range of the charging receiving parameter corresponding to each receiving function field.

[0225] The apparatus 1100 can also be a wireless receiving device (e.g., an electric vehicle) in any of the embodiments described above, or can also be a chip or module set provided in a wireless receiving device. The processing unit 1102 can support the apparatus 1100 to perform the actions of the wireless receiving device in each of the method examples above, and the communication unit 1103 can support the communication between the apparatus 1100 and the wireless transmitting device.

[0226] Specifically, in one embodiment, the communication unit 1103 can receive the transmission standard information and the transmission parameter information from the wireless transmitting device, the transmission standard information can indicate at least one charging standard supported by the wireless transmitting device, and the transmission parameter information can indicate the charging transmission parameters corresponding to the at least one charging standard respectively in the wireless transmitting device. When the processing unit 1102 determines that the target charging standard of the apparatus 1100 is included in the at least one charging standard according to the transmission standard information, the processing unit 1102 can obtain the charging transmission parameters conforming to the target charging standard according to the transmission parameter information. The processing unit 1102 can further determine whether the wireless transmitting device and the apparatus 1100 can interoperate according to the charging transmission parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard in the apparatus 1100.

[0227] For example, the charging transmission parameters include at least one of the following parameters in the wireless transmitting device: output power level, compensation network structure, self-induction range of the transmitting coil, coupling coefficient range, operating frequency range, and maximum adjustable current of the transmitting coil; and / or, the charging receiving parameters include at least one of the following parameters in the apparatus 1100: receiving power level, compensation network structure, ground clearance type of the receiving coil, self-induction range of the receiving coil, coupling coefficient range, operating frequency range, and maximum operating current of the receiving coil.

[0228] It can be understood that when the processing unit 1102 determines that the target charging standard is not included in the at least one charging standard according to the transmission standard information, the processing unit 1102 can directly determine that the wireless transmitting device and the apparatus 1100 cannot interoperate.

[0229] For example, when the processing unit 1102 determines whether the wireless transmitting device and the apparatus 1100 can interoperate according to the charging transmission parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard in the apparatus 1100, the processing unit 1102 can determine that the wireless transmitting device and the apparatus 1100 can interoperate when the charging transmission parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard match, and can determine that the wireless transmitting device and the apparatus 1100 cannot interoperate when the charging transmission parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard do not match.

[0230] Exemplarily, the transmission standard information can be carried in a first transmission message, the first transmission message comprising at least one transmission standard field, and the at least one transmission standard field corresponding to at least one charging standard in a one-to-one manner. A value of each transmission standard field is used to indicate whether the wireless transmission device supports the charging standard corresponding to the transmission standard field.

[0231] Exemplarily, the transmission parameter information can be carried in a second transmission message, the second transmission message comprising at least one transmission function field, and the at least one transmission function field corresponding to at least one charging transmission parameter in a one-to-one manner. A value of each transmission function field is used to indicate a value or a value range of the charging transmission parameter corresponding to the transmission function field.

[0232] In a possible implementation, after determining whether the wireless transmission device and the wireless reception device can interoperate, the communication unit 1103 can further send third indication information to the wireless transmission device, the third indication information indicating whether the wireless transmission device and the device 1100 can interoperate.

[0233] After the processing unit 1102 determines whether the wireless transmission device and the device 1100 can interoperate, if the wireless transmission device and the device 1100 can interoperate, the processing unit 1102 can control the device 1100 to perform wireless charging with the wireless transmission device.

[0234] Based on the same technical concept, the embodiments of the present application further provide a device, which can be a wireless transmission device. Exemplarily, as shown in the wireless charging station 20 in Figure 1 The device provided by the embodiments of the present application can comprise a transmission control module 202 and a transmission communication module 204. The transmission control module 202 can support the device to perform the actions of the wireless transmission device in the above method examples, and the transmission communication module 204 can support the communication between the device and the wireless reception device.

[0235] Specifically, in one embodiment, the transmission communication module 204 can receive reception standard information and reception parameter information from the wireless reception device, the reception standard information indicating a target charging standard of the wireless reception device, and the reception parameter information indicating charging reception parameters in the wireless reception device that meet the provision of the target charging standard.

[0236] The transmission control module 202 can acquire charging transmission parameters in the device that meet the provision of the target charging standard when it is determined according to the reception standard information that the device supports the target charging standard, and determine whether the device and the wireless reception device can interoperate according to the charging transmission parameters that meet the provision of the target charging standard and the charging reception parameters.

[0237] Exemplarily, the charging transmission parameters include at least one of the following parameters in the apparatus: an output power level, a compensation network structure, a self-inductance range of the transmission coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmission coil; and / or the charging receiving parameters include at least one of the following parameters in the wireless receiving apparatus: a receiving power level, a compensation network structure, a ground clearance type of the receiving coil, a self-inductance range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0238] It can be understood that the transmission control module 202 can also determine that the apparatus and the wireless receiving apparatus cannot interoperate when it is determined according to the receiving standard information that the apparatus does not support the target charging standard.

[0239] Exemplarily, the transmission control module 202 can determine that the apparatus and the wireless receiving apparatus can interoperate when the charging transmission parameters and the charging receiving parameters conform to the target charging standard, and can determine that the apparatus and the wireless receiving apparatus cannot interoperate when the charging transmission parameters and the charging receiving parameters do not conform to the target charging standard.

[0240] Exemplarily, the receiving standard information can be carried in a first receiving message, the first receiving message including at least one receiving standard field, and the at least one receiving standard field corresponding to at least one charging standard in a one-to-one manner; wherein a value of each receiving standard field is used to indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0241] Exemplarily, the receiving parameter information can be carried in a second receiving message, the second receiving message including at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter in a one-to-one manner; wherein a value of each receiving function field is used to indicate a value or a value range of the charging receiving parameter corresponding to each receiving function field.

[0242] In a possible implementation, the transmission communication module 204 can also send first indication information to the wireless receiving apparatus, the first indication information indicating whether the apparatus and the wireless receiving apparatus can interoperate.

[0243] Generally, after it is determined that the apparatus and the wireless receiving apparatus can interoperate wirelessly, the apparatus can perform wireless charging with the wireless receiving apparatus. Therefore, the transmission control module 202 can also control the apparatus to perform wireless charging with the wireless receiving apparatus when the apparatus and the wireless receiving apparatus can interoperate.

[0244] Based on the same technical concept, the embodiment of the present application also provides a device, which can be the management server in the above embodiment. Figure 12 As shown, the device 1200 includes: a processor 1202, a transceiver 1203, and a memory 1201. Optionally, the device 1200 may further include a bus 1204. The transceiver 1203, the processor 1202, and the memory 1201 may be interconnected via the bus 1204; the bus 1204 may be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus. The bus 1204 may be divided into an address bus, a data bus, a control bus, and the like. For ease of representation, Figure 12 Only one thick line is used in the diagram, but this does not mean that there is only one bus or one type of bus.

[0245] The processor 1202 may be a CPU, a microprocessor, an ASIC, or one or more integrated circuits for controlling the execution of the program of the present application.

[0246] The transceiver 1203 is used to communicate with other devices or communication networks, such as Ethernet, RAN, wireless local area networks (WLAN), wired access networks, etc.

[0247] The memory 1201 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including a compact disc, laser disc, optical disc, digital versatile disc, Blu-ray disc, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 1201 may exist independently and be connected to the processor 1202 via the bus 1204. The memory 1201 may also be integrated with the processor 1202.

[0248] The memory 1201 is configured to store computer-executable instructions for implementing the solutions of the present application, and the processor 1202 is configured to execute the computer-executable instructions stored in the memory 1201. The processor 1202 is configured to execute the computer-executable instructions stored in the memory 1201, so as to implement the method for determining interoperation provided in the embodiments of the present application.

[0249] Specifically, in one embodiment, the transceiver 1203 can receive receiving standard information and receiving parameter information from the wireless receiving device. The receiving standard information can indicate a target charging standard of the wireless receiving device, and the receiving parameter information can indicate charging receiving parameters in the wireless receiving device that meet the target charging standard. The processor 1202 can determine at least one first wireless transmitting device that supports the target charging standard from at least one wireless transmitting device according to the receiving standard information. The processor 1202 can further acquire charging transmitting parameters in the at least one first wireless transmitting device that meet the target charging standard, respectively. Then, the processor 1202 can determine a target transmitting device from the at least one first wireless transmitting device according to the receiving parameter information, wherein the charging transmitting parameters in the target transmitting device match the charging receiving parameters.

[0250] Exemplary charging transmitting parameters include at least one of the following parameters in the wireless transmitting device: an output power level, a compensation network structure, a self-induction range of a transmitting coil, a coupling coefficient range, an operating frequency range, and a maximum adjustable current of the transmitting coil; and / or, exemplary charging receiving parameters include at least one of the following parameters in the wireless receiving device: a receiving power level, a compensation network structure, a ground clearance type of a receiving coil, a self-induction range of the receiving coil, a coupling coefficient range, an operating frequency range, and a maximum operating current of the receiving coil.

[0251] In one possible implementation, after determining the target transmitting device from the at least one first wireless transmitting device, the transceiver 1203 can further send second indication information to the wireless receiving device, where the second indication information is used to instruct the wireless receiving device to perform wireless charging with the target transmitting device.

[0252] Exemplarily, the receiving standard information can be carried in a first receiving message, where the first receiving message includes at least one receiving standard field, and the at least one receiving standard field corresponds to at least one charging standard in a one-to-one manner. The value of each receiving standard field can indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

[0253] Exemplarily, the receiving parameter information can be carried in a second receiving message, the second receiving message comprising at least one receiving function field, and the at least one receiving function field corresponding to at least one charging receiving parameter. A value of each receiving function field can indicate a value or a value range of the charging receiving parameter corresponding to the receiving function field.

[0254] Based on the same technical concept, the embodiments of the present application further provide a device, which can be a wireless receiving device. Exemplarily, as shown in the electric vehicle 10 in Figure 1 The device provided by the embodiments of the present application can comprise a receiving control module 102 and a receiving communication module 104. The receiving control module 102 can support the device to perform the actions of the wireless receiving device in the above method examples, and the receiving communication module 104 can support the communication between the device and the wireless transmitting device.

[0255] Specifically, in one embodiment, the receiving communication module 104 can receive the transmitting standard information and the transmitting parameter information from the wireless transmitting device, the transmitting standard information can indicate at least one charging standard supported by the wireless transmitting device, and the transmitting parameter information can indicate the charging transmitting parameters corresponding to the at least one charging standard respectively in the wireless transmitting device. When the receiving control module 102 determines that the target charging standard including the device 1100 is not included in the at least one charging standard according to the transmitting standard information, the receiving control module 102 can directly determine that the wireless transmitting device and the device 1100 cannot interoperate.

[0256] Exemplarily, the charging transmitting parameters comprise at least one of the following parameters in the wireless transmitting device: output power level, compensation network structure, self-induction range of the transmitting coil, coupling coefficient range, working frequency range, and maximum adjustable current of the transmitting coil; and / or, the charging receiving parameters comprise at least one of the following parameters in the device 1100: receiving power level, compensation network structure, ground clearance type of the receiving coil, self-induction range of the receiving coil, coupling coefficient range, working frequency range, and maximum working current of the receiving coil.

[0257] It can be understood that when the receiving control module 102 determines that the target charging standard is not included in the at least one charging standard according to the transmitting standard information, the receiving control module 102 can directly determine that the wireless transmitting device and the device 1100 cannot interoperate.

[0258] For example, the receiving control module 102 can determine whether the wireless transmitting device and the device 1100 can interoperate based on the charging transmitting parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard in the device 1100. When the charging transmitting parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard match, the receiving control module 102 can determine that the wireless transmitting device and the device 1100 can interoperate. When the charging transmitting parameters conforming to the target charging standard and the charging receiving parameters conforming to the target charging standard do not match, the receiving control module 102 can determine that the wireless transmitting device and the device 1100 cannot interoperate.

[0259] For example, the transmitting standard information can be carried in a first transmitting message, the first transmitting message including at least one transmitting standard field, and the at least one transmitting standard field corresponding to at least one charging standard in a one-to-one manner. The value of each transmitting standard field is used to indicate whether the wireless transmitting device supports the charging standard corresponding to each transmitting standard field.

[0260] For example, the transmitting parameter information can be carried in a second transmitting message, the second transmitting message including at least one transmitting function field, and the at least one transmitting function field corresponding to at least one charging transmitting parameter in a one-to-one manner. The value of each transmitting function field is used to indicate the value or value range of the charging transmitting parameter corresponding to each receiving function field.

[0261] In a possible implementation, after the receiving control module 102 determines whether the wireless transmitting device and the wireless receiving device can interoperate, the receiving communication module 104 can further send third indication information to the wireless transmitting device, the third indication information indicating whether the wireless transmitting device and the device 1100 can interoperate.

[0262] After the receiving control module 102 determines whether the wireless transmitting device and the device 1100 can interoperate, if the wireless transmitting device and the device 1100 can interoperate, the receiving control module 102 can control the device 1100 to perform wireless charging with the wireless transmitting device.
