The electric automobile is a vehicle which takes a vehicle-mounted power supply as power, utilizes a motor to drive wheels to run and accords with various requirements of road traffic and safety regulations. The on-board power supply in an electric vehicle is generally a battery that can be repeatedly charged and discharged. At present, the method for charging the electric vehicle mainly comprises the following steps: contact charging and wireless charging. Compared with contact charging, the wireless charging device has the advantages of convenience in use, no spark, no electric shock hazard, no mechanical abrasion, adaptability to various severe environments and weathers, convenience in realizing unmanned automatic charging, movable charging and the like, and therefore the wireless charging device is likely to become a mainstream mode of charging for future electric vehicles.

For an electric automobile supporting wireless charging, a receiving coil is arranged inside the electric automobile, and the receiving coil is generally located at a chassis of the electric automobile. The power transmitter outside the electric vehicle includes a transmitter coil, which is usually disposed on the ground or buried in the ground. When wireless charging, electric automobile berths above transmitting coil, makes transmitting coil and receiving coil can couple, can transmit energy through electromagnetic coupling between transmitting coil and the receiving coil, and then can realize wireless charging.

However, wireless charging standards in the electric vehicle industry are not unified at present, and common wireless charging standards mainly include a chinese national standard scheme, an International Electrotechnical Commission (IEC) international standard scheme, an international organization for standardization (ISO) international standard scheme, an american national standard recommendation (SAE), and the like. Under different wireless charging standards, different charging parameter types and/or charging parameter ranges are further specified. Due to the fact that the wireless charging standards of the existing electric automobile industry are complex and various, the wireless transmitting device possibly cannot wirelessly charge all types of electric automobiles, namely, the wireless transmitting device and part of electric automobiles possibly cannot be interoperated, and further inconvenience is brought to electric automobile users.

Therefore, the current wireless charging technology needs further research.

Disclosure of Invention

The application provides an interoperation judging method and device, a wireless charging system and an electric automobile.

In a first aspect, an embodiment of the present application provides an interoperation determination method, which may be applied to a wireless transmitting apparatus. Illustratively, the method essentially comprises: the wireless transmitting apparatus receives the reception standard information and the reception parameter information from the wireless receiving apparatus. The receiving standard information may indicate a target charging standard of the wireless receiving device, and the receiving parameter information may indicate a charging receiving parameter in the wireless receiving device, which meets the target charging standard. And the wireless transmitting device acquires the charging transmission parameters which are in line with the target charging standard in the wireless transmitting device when determining the 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 which are in accordance with the target charging standard.

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

Illustratively, the charging transmission parameter includes at least one of the following parameters in the wireless transmission device: the output power level, the compensation network structure, the self-inductance range of the transmitting coil, the coupling coefficient range, the working frequency range and the maximum adjustable current of the transmitting coil; and/or the charging receiving parameter comprises at least one of the following parameters in the wireless receiving device: the device comprises a receiving power grade, a compensation network structure, a ground-to-ground distance 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.

By adopting the interoperation judging method provided by the embodiment of the application, whether the wireless transmitting device and the wireless receiving device can interoperate can be judged. The wireless transmitting device can judge whether the wireless transmitting device and the wireless receiving device can interoperate before the wireless transmitting device and the wireless receiving device start charging. If the wireless transmitting device and the wireless receiving device can not be mutually operated, the wireless transmitting device and the wireless receiving device can not be wirelessly charged, so that the safety of the wireless transmitting device and the wireless receiving device can be protected, and inconvenience brought to users due to the fact that the wireless transmitting device and the wireless receiving device can not be mutually operated can be reduced.

It is understood that the wireless transmission apparatus may determine that the wireless transmission apparatus and the wireless reception apparatus are not interoperable when it is determined from the reception standard information that the wireless transmission apparatus does not support the target charging standard.

Generally, when the wireless transmitting device and the wireless receiving device support the same charging standard, the two devices may interoperate with each other. Therefore, after determining that the target charging standard is not supported, the wireless transmitting device may determine that the wireless transmitting device and the wireless receiving device are not interoperable.

For example, when determining whether the wireless transmitting apparatus and the wireless receiving apparatus are interoperable according to the first charging transmission parameter and the charging receiving parameter, the wireless transmitting apparatus may determine that the wireless transmitting apparatus and the wireless receiving apparatus are interoperable when the charging transmission parameter and the charging receiving parameter that meet the target charging standard match, and determine that the wireless transmitting apparatus and the wireless receiving apparatus are not interoperable when the charging transmission parameter and the charging receiving parameter that meet the target charging standard do not match.

Generally, the wireless transmitting device may have at least one charging transmitting parameter, and the wireless receiving device may receive the at least one charging transmitting parameter. Since both the wireless transmitter and the wireless receiver support the target charging standard, the at least one charging transmission parameter of the wireless transmitter and the at least one charging reception parameter of the wireless receiver may be in a one-to-one correspondence. The wireless transmitting device may determine whether each charging transmission parameter matches the charging receiving parameter corresponding to the charging transmission parameter according to the correspondence. When all the charging transmission parameters are matched with the corresponding charging receiving parameters, the wireless transmitting device and the wireless receiving device can be considered to be capable of interoperating. When there is at least one charging transmission parameter not matching with the corresponding charging reception parameter, it may be considered that the wireless transmission device and the wireless reception device are not interoperable.

The charging transmission parameter and the charging receiving parameter are matched, that is, the wireless transmitting device can work safely and efficiently under the condition that the wireless receiving device supports the wireless receiving parameter, and the wireless receiving device can work safely and efficiently under the condition that the wireless transmitting parameter is supported. If the wireless transmitting device cannot safely and efficiently operate under the condition of supporting the wireless receiving parameter, or if the wireless receiving device cannot safely and efficiently operate under the condition of supporting the wireless transmitting parameter, it may be considered that the charging transmitting parameter and the charging receiving parameter are not matched.

For example, the receiving standard information may 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 one to one. And the value of each receiving standard field is used for indicating whether the charging standard corresponding to each receiving standard field is the target charging standard.

On the basis of this, the wireless receiving apparatus can transmit the reception standard information to the wireless transmitting apparatus through the first reception message.

For example, the receiving parameter information may be carried in a second receiving message, where the second receiving message includes at least one receiving function field, and the at least one receiving function field corresponds to at least one charging receiving parameter one to one. And the value of each receiving function field is used for indicating the value or the value range of at least one charging receiving parameter corresponding to each receiving function field.

In one possible implementation manner, after determining whether the wireless transmitting apparatus and the wireless receiving apparatus are interoperable, the wireless transmitting apparatus may further send first indication information to the wireless receiving apparatus, where the first indication information may indicate whether the wireless transmitting apparatus and the wireless receiving apparatus are interoperable. That is, the wireless transmitting apparatus may inform the wireless receiving apparatus of the result of the interoperation determination through the first indication information.

Generally, the interoperation determination may be performed before the wireless charging is started. After the wireless transmitting device determines whether the wireless transmitting device and the wireless receiving device can interoperate, the wireless transmitting device can also wirelessly charge with the wireless receiving device when the wireless transmitting device and the wireless receiving device can interoperate.

In a second aspect, an embodiment of the present application provides an interoperation determination method, which may be applied to a management server, where the management server may control at least one wireless transmission apparatus. Technical effects of corresponding schemes in the second aspect can refer to technical effects obtained by corresponding schemes in the first aspect, and repeated parts are not detailed. Illustratively, the interoperation determination method mainly includes: the management server receives the reception standard information and the reception parameter information from the wireless reception device. The receiving standard information may indicate a target charging standard of the wireless receiving device, and the receiving parameter information may indicate a charging receiving parameter in the wireless receiving device, which meets the target charging standard. The management server may determine, from the at least one wireless transmission apparatus, at least one first wireless transmission apparatus supporting the target charging standard according to the reception standard information. The management server can further acquire charging transmission parameters which are in accordance with the target charging standard and are regulated in the at least one first wireless transmission device respectively. Then, the management server may determine a target transmitting device from the at least one first wireless transmitting device according to the receiving parameter information, wherein the charging transmitting parameter meeting the target charging standard is matched with the charging receiving parameter.

Exemplary charging transmission parameters include at least one of the following in a wireless transmitting device: the output power grade, the compensation network structure, the self-inductance range of the transmitting coil, the coupling coefficient range, the working frequency range and the maximum adjustable current of the transmitting coil; and/or the charging receiving parameter comprises at least one of the following parameters in the wireless receiving device: the device comprises a receiving power grade, a compensation network structure, a ground-to-ground distance 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.

By adopting the interoperation judging method, the management server can determine the target wireless transmitting device capable of interoperating with the wireless receiving device from at least one wireless transmitting device controlled by the management server. Make wireless receiving arrangement's user can directly use wireless transmitting device to carry out wireless charging, the user need not to look for by oneself can with wireless receiving arrangement interoperation's wireless transmitting device, is favorable to improving user's use and experiences.

In one possible implementation manner, after determining the target transmitting device from the at least one first wireless transmitting device, the management server may further send second indication information to the wireless receiving device, where the second indication information is used to indicate that the wireless receiving device and the target transmitting device perform wireless charging.

For example, the receiving standard information may 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 one to one. The value of each receiving standard field may indicate whether the charging standard corresponding to each receiving standard field is the target charging standard.

For example, the receiving parameter information may be carried in a second receiving message, where the second receiving message includes at least one receiving function field, and the at least one receiving function field corresponds to at least one charging receiving parameter. The value of each receiving function field may indicate a value or a value range of the charging receiving parameter corresponding to each receiving function field.

In a third aspect, an embodiment of the present application provides an interoperability determining method, which may be applied to a wireless receiving apparatus. Technical effects of corresponding solutions in the second aspect can be referred to technical effects that can be obtained by corresponding solutions in the first aspect, and repeated parts are not detailed. Illustratively, the interoperation determination method mainly includes: the wireless receiving device receives transmission standard information and transmission parameter information from the wireless transmitting device, the transmission standard information may indicate at least one charging standard supported by the wireless transmitting device, and the transmission parameter information may indicate charging transmission parameters respectively corresponding to the at least one charging standard in the wireless transmitting device. And the wireless receiving device acquires the charging transmission parameters meeting the requirements of the target charging standard according to the transmission parameter information when determining that the at least one charging standard comprises the target charging standard of the wireless receiving device according to the transmission standard 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 meeting the target charging standard and the charging receiving parameters meeting the target charging standard in the wireless receiving device.

By adopting the interoperation judging method provided by the embodiment of the application, whether the wireless transmitting device and the wireless receiving device can interoperate can be judged. The wireless receiving device can judge whether the wireless receiving device and the wireless transmitting device can interoperate before the wireless receiving device and the wireless transmitting device start charging. If the wireless transmitting device and the wireless receiving device can not be mutually operated, the wireless receiving device can not be wirelessly charged with the wireless receiving device, so that the safety of the wireless transmitting device and the wireless receiving device can be protected, and inconvenience brought to users due to the fact that the wireless transmitting device and the wireless receiving device can not be mutually operated can be reduced. For example, if the wireless receiving device is an electric vehicle and the wireless transmitting device is a wireless charging station, the electric vehicle may determine whether the electric vehicle can interoperate with the wireless charging station before the electric vehicle travels to the wireless charging station. If interoperability is not possible, other wireless charging stations may be selected immediately. Therefore, the use experience of the user is improved.

It is to be understood that the wireless receiving apparatus may directly determine that the wireless transmitting apparatus and the wireless receiving apparatus are not interoperable when it is determined that the target charging standard of the wireless receiving apparatus is not included in the at least one charging standard based on the transmission standard information.

For example, when the wireless receiving device determines whether the wireless transmitting device and the wireless receiving device are interoperable according to the charging transmission parameter complying with the target charging standard specification and the charging receiving parameter complying with the target charging standard specification in the wireless receiving device, the wireless receiving device may determine that the wireless transmitting device and the wireless receiving device are interoperable when the charging transmission parameter complying with the target charging standard specification and the charging receiving parameter complying with the target charging standard specification match, and determine that the wireless transmitting device and the wireless receiving device are not interoperable when the charging transmission parameter complying with the target charging standard specification and the charging receiving parameter complying with the target charging standard specification do not match.

For example, the transmission standard information may 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 corresponds to at least one charging standard one to one. And the value of each transmission standard field is used for indicating whether the wireless transmitting device supports the charging standard corresponding to each transmission standard field.

For example, the transmission parameter information may be carried in a second transmission message, where the second transmission message includes at least one transmission function field, and the at least one transmission function field corresponds to the at least one charging transmission parameter one-to-one. And the value of each transmitting function field is used for indicating the value or the value range of the charging transmitting parameter corresponding to each receiving function field.

In one possible implementation, after determining whether the wireless transmitting apparatus and the wireless receiving apparatus are interoperable, the wireless receiving apparatus may further send third indication information to the wireless transmitting apparatus, where the third indication information may indicate whether the wireless transmitting apparatus and the wireless receiving apparatus are interoperable. That is, the wireless receiving apparatus may notify the wireless transmitting apparatus of the result of the interoperation determination through the third indication information.

After the wireless receiving device determines whether the wireless transmitting device and the wireless receiving device can interoperate, the wireless receiving device can wirelessly charge with the wireless transmitting device when the wireless transmitting device and the wireless receiving device can interoperate.

Wireless charging may become the mainstream way of charging electric vehicles in the future. Fig. 1 illustrates a common wireless charging scenario. As shown in fig. 1, the wireless charging system 00 mainly includes an electric vehicle 10, a wireless charging station 20, and a power supply 30. The wireless charging station 20 may be a fixed wireless charging station, a fixed wireless charging parking space, a wireless charging road, or the like. The wireless charging station 102 may be located on the ground or buried below the ground (as shown in fig. 1). In the wireless charging, the electric vehicle 10 is located above the wireless charging station 20. The wireless charging station 20 may receive the power provided by the power source 30 and provide the power to the electric vehicle in the form of wireless energy.

Next, the electric vehicle 10, the wireless charging station 20, and the power supply 30 will be further exemplified, respectively.

1. Electric automobile 10

As shown in fig. 1, the electric vehicle 10 mainly includes a power receiving module 101, a reception control module 102, a reception conversion module 103, an energy storage module 104, and a reception communication module 105. The reception control module 102 is connected to the reception communication module 105 and the reception conversion module 103, respectively. The receiving conversion module 103 is also connected with the power receiving module 101 and the energy storage module 104 respectively. Wherein:

the power receiving module 101 is mainly used for receiving wireless energy transmitted by the wireless charging station 20. Illustratively, as shown in fig. 2, the power receiving module 101 mainly includes a receiving coil Ls and a compensating network 1. The receiving coil Ls is mainly used for being electromagnetically coupled with the transmitting coil Lp in the power transmitting module 201, so that the wireless energy transmitted by the power transmitting module 201 can be received.

In general, the compensation network 1 may be formed by one or more capacitors, and/or one or more inductors. There are many possible network configurations of the compensation network 1, for example, the compensation network 1 comprises a capacitor, which is connected in series with the receiving coil Ls (S-type), or which is connected in series with the receiving coil Ls (P-type). As another example, the compensation network 1 includes two inductors and one capacitor (LCL type). As another example, the compensation network 1 may further include two capacitors and an inductor (LCC type), and so on, which are not listed in this embodiment.

In some scenarios, the receiving communication module 105 may also communicate with a smart terminal of a user of the electric vehicle 10, so that the user may implement remote control through a communication function.

2. Wireless charging station 20

As shown in fig. 1, the wireless charging station 20 mainly includes a power transmitting 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 with the power transmission module 201 and the power supply 30 respectively. Wherein:

the power transmitting module 201 is mainly used for transmitting wireless energy to the electric vehicle 10. Illustratively, as shown in fig. 2, 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.

The compensation network 2 can adjust the output equivalent impedance of the transmission transformation module 203, so that the power switch tube in the transmission transformation module 203 can realize soft switching. Similar to the compensation network 1, there are many possible network configurations for the compensation network 2, which are not listed.

The transmission control module 202 may implement or execute the various illustrative logical blocks, modules, and circuits described in connection with the present disclosure. The receive control module 102 may also be a combination that performs a computational function, including for example, one or more microprocessor combinations, a combination of a DSP and a microprocessor, or the like. The transmitting control module 202 can adjust the input/output voltage, the input/output current, the frequency conversion parameter, and the like of the transmitting conversion circuit 203 according to the transmitting power requirement of the actual wireless charging, and control the output voltage and the operating current of the transmitting coil Ls in the power transmitting module 201.

The transmission converting module 203 may be connected to the power supply 30, obtain power from the power supply 30, convert the power obtained from the power supply 30 into ac power under the control of the transmission control module 202, and provide the ac power to the power transmitting module 201. The electric energy obtained from the power supply 30 may be ac electric energy or dc electric energy, and there are many possible specific implementation manners of the transmission conversion module 203.

Specifically, when the power output by the power supply 30 is ac power, the transmission conversion module 203 may 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 so as to reduce the pollution to the power supply 30. The transmission control module 202 may also increase or decrease the output voltage of the power factor correction circuit according to the requirements of the subsequent stage (the power transmission module 201). The inverter circuit may convert the output voltage of the power factor correction circuit into an alternating voltage and provide the alternating voltage to the power transmission module 201.

When the electric energy output by the power supply 30 is dc electric energy, the transmitting and converting module 203 may include an inverter circuit, which is not described in detail herein.

The specific implementation of the transmitting communication module 204 is similar to that of the receiving communication module 105, and is not described in detail here.

It should be noted that the above modules are merely examples, and other modules may be included in the wireless charging station 20 in addition to the above modules. For example, the wireless charging station 20 may further include an authentication management module, and the authentication management module may authenticate and manage the authority of the electric vehicle 10. For example, the authentication management module may authenticate whether the electric vehicle 10 has the authority to use the wireless charging station 20 for charging.

For another example, the wireless charging station 20 may further include a storage module, and the storage module may store data generated during the wireless charging process, mutual authentication data (for example, mutual authentication information), and authority management data (for example, authority management information), where the mutual authentication data and the authority management data may be set by a factory or a user, and the embodiment of the present application is not limited to this.

3. Power supply 30

The power source 30 may be a power grid, a high power battery, or other device or apparatus capable of outputting electrical energy. In the case that the power supply 30 is a large power battery, the power supply 30 may be located outside the wireless charging station 20, or may be integrated inside the wireless charging station 20, which is not limited in this embodiment.

As can be seen from the above description of the wireless charging system 00, the wireless charging can be realized by relying 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 referred to as interoperation. That is, only in the case where the interoperation between the electric vehicle 10 and the wireless charging station 20 is enabled, the safe and efficient wireless charging can be achieved.

Generally, the interoperation between the electric vehicle 10 and the wireless charging station 20 is possible only in the case where the electric vehicle 10 and the wireless charging station 20 support the same charging standard. Charging standards specify aspects of wireless charging. Taking the chinese national standard scheme as an example, in the chinese national standard scheme "part 3 of the wireless charging system for electric vehicles: the ground clearance of the receiving coil is defined in the special requirement, as shown in the following table one:

watch 1

Types of	Ground clearance (mm)
Z1	100～150
Z2	140～210
Z3	170～250
Z4	≥250

As shown in table one, the ground clearance of the receiving coil is divided into 4 types (type Z1 to type Z4) in the chinese national standard scheme, and each type corresponds to a different ground clearance range.

Part 1 of the wireless charging system for electric vehicles in the scheme of the Chinese national standard: the input power level of the power transmission means 201 is also specified in the general requirements. As shown in table two:

watch 2

As shown in table two, the input power of the power transmitting apparatus 201 is divided into 7 levels in the chinese national standard scheme, and each level corresponds to a different power range.

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. In practice, however, it is difficult to perfectly align the transmitter coil and the receiver coil, so the allowable offset range is also specified in the chinese national standard scheme: the offset range in the X direction (the head and tail directions of the electric vehicle 10) is ± 75mm, and the offset range in the Y direction (the door directions on both sides of the electric vehicle 10) is ± 100mm.

As can be seen, the charging standards specify various aspects of the electric vehicle 10 and the wireless charging station 20. Both the manufacturer of the electric vehicle 10 and the manufacturer of the wireless charging station 20 can produce the electric vehicle 10 and the wireless charging station 20 as specified in the charging standard.

However, there is no unified standard in the current wireless charging field. For example, in addition to the above-mentioned international national standard scheme, the currently common charging standards include an IEC international standard scheme, an ISO international standard scheme, a U.S. international recommended scheme, and the like. Different types of charging parameters are specified in different charging standards, 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 manner of the charging power, the ground clearance of the receiving coil, the power level division, the offset range, and so on.

For manufacturers of electric vehicles 10, electric vehicles 10 are often manufactured to only one of the charging standards. In order to be able to accommodate more types of electric vehicles 10, current wireless charging stations 20 are able to support more and more charging standards. However, even if the wireless charging station 20 is compatible with multiple charging standards, there is no guarantee that the wireless charging station 20 will interoperate with all types of electric vehicles 10.

If the wireless charging station 20 is unable to interoperate with the electric vehicle 10, the wireless charging station 20 may not be able to charge the electric vehicle 10 and may even damage the electric vehicle 10 or the wireless charging station 20. Especially when the wireless charging station 20 is a public wireless charging station, it is possible for the electric vehicle 10 charged using the wireless charging station 20 to support any type of charging standard. Under the circumstances, 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 urgently in the field of wireless charging.

In view of the above, the present disclosure provides an interoperability judging method, which can be applied to a wireless transmitting apparatus or a wireless receiving apparatus. The wireless transmitting device may be the wireless charging station 20, or may be a chip or a module set used in the wireless charging station 20 for wireless charging. The wireless receiving device may be an electronic device such as an electric vehicle 10 or an electric unmanned aerial vehicle, or may be a chip or a module set used for wireless charging in the electronic device such as the electric vehicle 10 or the electric unmanned aerial vehicle.

Before wireless charging is carried out between the wireless transmitting device and the wireless receiving device, interoperation judgment is carried out. After the interoperation is confirmed, wireless charging is carried out, so that the safety of the wireless transmitting device and the wireless receiving device is guaranteed, and the use experience of a user is improved.

For convenience of understanding, in the embodiment of the present application, a wireless transmitting device is taken as the wireless charging station 20, and a wireless receiving device is taken as the electric vehicle 10 for example, which will not be described again.

Next, the interoperation determination method provided in the embodiments of the present application is further exemplarily described by the following examples.

Example one: wireless charging station 20 interoperation determination

Fig. 3 schematically illustrates a flow chart of an interoperation determination method provided in an embodiment of the present application. As shown in fig. 3, the interoperation determination method mainly includes the following steps:

s301: the wireless charging station 20 receives the reception standard information and the reception parameter information from the electric vehicle 10. The reception standard information may indicate a target charging standard of the electric vehicle 10, which may be a charging standard supported by the electric vehicle 10. The reception parameter information may indicate a charge reception parameter in the electric vehicle 10 that meets the target charge standard.

For example, the reception standard information and the reception parameter information may be directly sent to the wireless charging station 20 by the electric vehicle 10, or may be sent to other devices by the electric vehicle 10, and then forwarded to the wireless charging station 20 by the other devices, which is not limited in this embodiment of the present invention.

The charging reception parameter may be understood as a specific implementation of a plurality of charging parameters related to wireless charging specified by a target charging standard in the electric vehicle 10. For example, if the charging standard specifies the type of the ground clearance of the transmitting coil as shown in table one, the charging receiving parameter of the electric vehicle 10 may 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 may indicate any one of the types Z1 to Z4.

S302: the wireless charging station 20 acquires the charging transmission parameters in the wireless charging station 20, which meet the target charging standard, when it is determined that the wireless charging station 20 supports the target charging standard based on the reception standard information.

Specifically, the wireless charging station 20 may support a plurality of charging standards, and the wireless charging station 20 may determine whether the target charging standard is included in the plurality of charging standards supported by the wireless charging station 20 according to the reception standard information. For example, the wireless charging station 20 may support the chinese international recommendation, the IEC international standard and the U.S. international recommendation, and if the target charging standard supported by the electric vehicle 10 is any one of the three standards, the wireless charging station 20 may continue to perform S302.

As mentioned above, different charging standards specify different types of charging parameters, or specify different values or value ranges for the same charging parameter. Therefore, after determining that the target charging standard is supported, the wireless charging station 20 needs to acquire the charging transmission parameters in the wireless charging station 20, which meet the requirements of the target charging standard. The charging transmission parameter may be understood as a specific implementation of a plurality of charging parameters related to wireless charging specified by a target charging standard in the wireless charging station 20.

Taking the current chinese standard scheme as an example, if the interoperation between the electric vehicle 10 and the wireless charging station 20 is to be implemented, the charging transmission parameters may 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 transmitting coil, coupling coefficient range, working frequency range, maximum adjustable current of the transmitting coil, and the like, which are not listed in the embodiments of the present application.

It is understood that if the target charging standard is not included in the plurality of charging standards supported by the wireless charging station 20, it may be directly determined that the wireless charging station 20 and the electric vehicle 10 cannot interoperate with each other.

It is noted that different charging standards specify (correspond to) different charging modes. For example, the charging mode 1 corresponds to the chinese national standard scheme, and the charging mode 2 corresponds to the us 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 the charging mode 1. If the electric vehicle 10 supports the recommended U.S. national standard, the charging mode of the electric vehicle 10 is charging mode 2.

In view of this, the reception standard information in the embodiment of the present application may also be understood as indicating the charging mode of the electric vehicle 10. In this case, the wireless charging station 20 may also determine whether the target charging standard is supported by determining whether the charging mode of the electric vehicle 10 is supported. It can be understood that the charging mode and the charging standard have the same function in the embodiment of the present application, and both the functions are to ensure the rationality of the subsequent parameter matching, that is, the matching between the charging parameters specified by different charging standards and the matching between the charging parameters in different charging modes are meaningless for the interoperation judgment. 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. For convenience of description, the charging standard will be described as an example.

S303: the wireless charging station 20 determines whether the wireless charging station 20 and the electric vehicle 10 can interoperate with each other based on the charging transmission parameter and the charging reception parameter that meet the target charging standard.

It can be understood that, since the charging transmission parameter and the charging reception parameter are both parameters that meet the target charging standard, the charging transmission parameter and the charging reception parameter are both corresponding to each other. For example, the charging transmission parameter may include an output power level of the wireless charging station 20, and the charging reception parameter may include a reception power level of the electric vehicle 10. The charging transmission parameters may include a maximum adjustable current of a transmission coil in the wireless charging station 20, the charging reception parameters may include a maximum operating current of the electric vehicle 10, and so on. This is not further illustrated in the embodiments of the present application.

For example, the wireless charging station 20 may determine whether the wireless charging station 20 and the electric vehicle 10 are interoperable according to whether the charging transmission parameter and the charging reception parameter match. Specifically, when the charging transmission parameter and the charging reception parameter match, the wireless charging station 20 may determine that the interoperation between the wireless charging station 20 and the electric vehicle 10 is possible. When the charging transmission parameter and the charging reception parameter do not match, it is determined that the wireless charging station 20 and the electric vehicle 10 cannot interoperate with each other.

Here, the charging transmission parameter and the charging reception parameter are matched, that is, the wireless charging station 20 can safely and efficiently operate in the presence of the wireless reception parameter, and meanwhile, the electric vehicle 10 can also safely and efficiently operate in the presence of the wireless transmission parameter. If the wireless charging station 20 cannot operate safely and efficiently while supporting the wireless receiving parameters, or if the electric vehicle 10 cannot operate safely and efficiently while supporting the wireless transmitting parameters, it may be determined that the charging transmitting parameters and the charging receiving parameters do not match.

For example, if the received power level of the electric vehicle 10 is MF-WPT5 and the transmission power level of the wireless charging station 20 is MF-WTP1, it is considered that the transmission power of the wireless charging station 20 does not match the received power of the electric vehicle 10, and the electric vehicle 10 and the wireless charging station 20 cannot interoperate with each other.

It should be noted that the charging transmission parameter and the charging reception parameter often include a plurality of parameters, and it can be determined that the electric vehicle 10 and the wireless charging station 20 can interoperate with each other in the case that all the charging transmission parameters and the corresponding charging reception parameters can be matched. If there is at least one charging transmission parameter that cannot be matched with the corresponding charging reception parameter, it may be determined that the electric vehicle 10 and the wireless charging station 20 cannot interoperate.

Next, the interoperation method provided by the embodiment of the present application is further exemplified by a flowchart shown in fig. 5. As shown in fig. 5, the method mainly comprises the following steps:

s501: the electric vehicle 10 transmits the reception standard information and the 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 a charging parameter that meets a target charging standard specification in the electric vehicle 10.

It is understood that before S501, a communication handshake may also be performed between the electric vehicle 10 and the wireless charging station 20 to establish a wireless communication link. For specific implementation, reference may be made to the prior art, which is not described in detail herein.

S502: the wireless charging station 20 determines whether the target charging standard is supported. If yes, go to S503, otherwise go to S506.

S503: the wireless charging station 20 acquires the charging transmission parameter corresponding to the target charging standard in the wireless charging station 20.

S504: the wireless charging station 20 determines whether the charging transmission parameter and the charging receiving parameter are matched. If so, go to step S505, otherwise, go to step S507.

S505: it is determined that the electric vehicle 10 and the wireless charging station 20 can interoperate with each other.

S506: it is determined that the electric vehicle 10 and the wireless charging station 20 cannot interoperate with each other.

S507: it is determined that the electric vehicle 10 and the wireless charging station 20 cannot interoperate with each other.

In one possible implementation manner, as shown in fig. 5, after determining whether the electric vehicle 10 and the wireless charging station 20 are interoperable, the wireless charging station 20 may further continue to perform S508: the first indication information is transmitted to the electric vehicle 10, and the first indication information may indicate to the electric vehicle 10 whether the wireless charging station 20 and the electric vehicle 10 are interoperable.

It should be understood that when the electric vehicle 10 transmits the reception standard information and the reception parameter information to the wireless charging station 20, the electric vehicle 10 does not need to stop above the wireless charging station 20. For example, the electric vehicle 10 may transmit the reception standard information and the reception parameter information to the wireless charging station 20 when driving to the wireless charging station 20 or before driving to the wireless charging station 20.

If the electric vehicle 10 and the wireless charging station 20 cannot interoperate with each other, the electric vehicle 10 may receive the first indication information before reaching the wireless charging station 20, and the user may immediately search for other available wireless charging stations, thereby facilitating the improvement of user experience.

If the electric vehicle 10 and the wireless charging station 20 can be operated with each other, the wireless charging station 20 can be charged with the electric vehicle 10 wirelessly. The specific process of wireless charging may refer to a conventional wireless charging scheme. Generally, the method mainly comprises the following steps:

the method comprises the following steps: and (4) aligning the positions. The electric vehicle 10 determines whether the offset distance between the transmission coil and the reception coil is within the offset range in which charging is possible. If not, the position adjustment continues until the offset distance between the transmitter coil and the receiver coil falls within the chargeable offset range. If within the offset range in which charging is possible, the electric vehicle 10 continues to detect the coupling coefficient. It is understood that this step may also be performed by the wireless charging station 20, and will not be described in detail.

Step two: the coupling coefficient is detected. The electric vehicle 10 detects the coupling coefficient between the transmitting coil and the receiving coil, sends a charging request to the wireless charging station 20 if the coupling coefficient is in a range in which the wireless charging station 20 and the electric vehicle 10 can normally operate, and the electric vehicle 10 continues to adjust the position until the coupling coefficient falls within a range in which the wireless charging station 20 and the electric vehicle 10 can normally operate if the coupling coefficient is not in a range in which the wireless charging station 20 and the electric vehicle 10 can normally operate.

Step three: the electric vehicle 10 transmits a charging request to the wireless charging station 20, and the wireless charging station 20 starts outputting wireless energy in response to the charging request, thereby starting charging.

It should be understood that the above steps one to three are only brief descriptions, and the specific implementation can refer to the prior art.

Next, specific implementations of the reception standard information and the reception parameter information will be further exemplified.

Receiving standard information

For example, the receiving standard information may 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 one to one. For example, as shown in fig. 4, the first received message includes at least 4 reception criteria fields: field a, field B, field C, and field D. The correspondence between the 4 receiving standard fields and the charging standard is shown in the following table four:

watch four

Receive standard field	Standard of charge
Field A	Chinese national standard recommendation scheme
Field B	IEC international standard scheme
Field C	ISO international standard scheme
Field D	American national standard recommendation scheme

As shown in table four, in the 4 reception standard fields of the first reception message, the field a corresponds to the chinese international standard recommendation scheme, the field B corresponds to the IEC international standard scheme, the field C corresponds to the ISO international standard scheme, and the field D corresponds to the U.S. international standard recommendation scheme.

In the first received message, the value of each reception standard field may indicate whether the charging standard corresponding to each reception standard field is the target charging standard of the electric vehicle 10. For example, the format of the first received message may be as shown in table five below:

watch five

As shown in table five, the first received message includes 2 bytes. In the first received message, the field a takes two bits starting from bit 1 (bit). When the value of the field a is 00, it means that the chinese national standard recommendation scheme is not the target charging standard, and when the value of the field a is 01, it means that the chinese national standard recommendation scheme is the target charging standard.

The field B starts with bit3 and occupies two bits. When the value of the field B is 00, it means that the IEC international standard scheme is not the target charging standard, and when the value of the field B is 01, it means that the IEC international standard scheme is the target charging standard.

The field C takes two bits, starting with bit 5. When the value of the field C is 00, it means that the ISO international standard scheme is not the target charging standard, and when the value of the field C is 01, it means that the ISO international standard scheme is the target charging standard.

The field D starts at bit7 and occupies two bits. When the value of the field D is 00, it means that the american national standard recommendation is not the target charging standard, and when the value of the field D is 01, it means that the american national standard recommendation is the target charging standard.

The fields a to D are parameters that must be carried in the first received message, i.e., mandatory parameters. In addition, there are 8 bytes as a reserved field, and the reserved field is an optional parameter. The reserved field starts at byte 9 and occupies 8 bytes. It is to be understood that the first received message may also include 1 byte without including the reserved field.

In addition, the first received message may also carry other information. For example, the first received message may also carry format information to indicate the format of the information in the first received message. Such as hexadecimal, octal, binary, etc.

Receiving parameter information

For example, the receiving parameter information may be carried in a second receiving message, where the second receiving message and the first receiving message may be the same message or different messages, and this is not limited in this embodiment of the present application. The second received message may include at least one receive function field, which may also be referred to as a function (function) code.

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

Illustratively, as shown in fig. 6, the second received message includes 9 received function fields: field 1 through field 9. The specific format of the second received message may be as shown in table six below:

watch six

As shown in table six and fig. 6, the second received message includes 8 bytes, and the 9 receiving function fields in the second received message correspond to the 9 charging receiving parameters, specifically:

the field 1 corresponds to the received power level of the electric vehicle 10, and the field 1 occupies positions from Bit2 to Bit0 in Byte1, and there are 8 possible values. Illustratively, a field 1 value of 000 indicates that the received power level of the electric vehicle 10 is MF-WPT1. When the field 1 takes a value of 001, the received power level of the electric vehicle 10 is indicated as MF-WPT2. And when the field 1 takes the value of 010, the received power level of the electric automobile 10 is MF-WPT3. Other possible values may then be reserved.

The field 2 corresponds to a compensation network structure in the electric vehicle 10, the field 2 occupies positions from Bit7 to Bit3 in Byte1, and there are 32 possible values. Illustratively, a field 2 value of 00000 indicates that the compensation network configuration of the electric vehicle 10 is an LCC-type configuration. And when the field 2 takes the value of 00001, indicating that the compensation network structure of the electric automobile 10 is a series structure. And when the field 2 is 00010, the compensation network structure of the electric automobile 10 is indicated to be a parallel structure. When the field 2 is 00011, the compensation network structure of the electric vehicle 10 is indicated as a series-parallel structure. Other possible values may then be reserved.

The field 3 corresponds to the ground clearance of the receiving coil in the electric vehicle 10, the field 3 occupies the positions from Bit2 to Bit0 in Byte2, and there are 8 possible values. Illustratively, a field 3 value of 000 indicates a ground clearance Z1 for the receiver coil in the electric vehicle 10. When the field 3 takes a value of 001, it indicates that the ground clearance of the receiving coil in the electric vehicle 10 is Z2. When the value of the field 3 is 010, it indicates that the ground clearance of the receiving coil in the electric vehicle 10 is Z3. Other possible values may then be reserved.

The field 4 corresponds to the self-inductance range of the transmitting coil supported by the electric vehicle 10, and the field 4 occupies the positions from Bit7 to Bit3 in Byte2, and there are 32 possible values. Illustratively, when the field 4 takes a value of 00000, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp1. When the field 4 takes a value of 00001, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp2. When the field 4 is 00010, it indicates that the self-inductance range of the transmitting coil supported by the electric vehicle 10 is Lp3. Other possible values may then be reserved.

The indication formats of other fields can be analogized, and the description is omitted.

Example two: management server interoperable determination

With the popularization of wireless charging technology, it is expected that large-scale wireless charging station clusters are expected to appear. For example, in a public parking lot, the wireless charging station may be arranged in the area where the parking space is located. In a possible implementation manner, as shown in fig. 7, the wireless charging system may further include a management server 40, and the management server 40 may collectively control at least one wireless charging station (the wireless charging station 20-1 to the wireless charging station 20-N, where N is an integer greater than or equal to 1).

In this case, the management server 40 may perform the interoperation determination, identify a wireless charging station capable of interoperating with the electric vehicle 10 from among at least one wireless charging station controlled by the interoperation determination, and charge the electric vehicle 10 by the wireless charging station. As an example, a method flow of the management server 40 for performing the interoperation determination may be as shown in fig. 8, and mainly includes the following steps:

s801: the management server 40 receives the reception standard information and the reception parameter information from the electric vehicle 10. The receiving standard information may indicate a target charging standard of the electric vehicle 10, and the receiving parameter information may indicate a charging receiving parameter in the electric vehicle 10, which meets the target charging standard. For a specific implementation manner of receiving the standard information and the parameter information, reference may be made to example one, which is not described again.

For example, the receiving standard information and the receiving parameter information may be directly sent to the management server 40 by the electric vehicle 10, or may be sent to other devices by the electric vehicle 10, and then forwarded to the management server 40 by the other devices, which is not limited in this embodiment of the application.

S802: the management server 40 determines at least one first wireless charging station that supports the target charging standard from among the at least one wireless charging station 20 it controls, according to the reception standard information.

For example, if the target charging standard is the chinese national standard recommended scheme, and the wireless charging station 20-1 to the wireless charging station 20-N support the chinese national standard recommended scheme for the wireless charging station 20-1 and the wireless charging station 20-2, the management server 40 may determine that the wireless charging station 20-1 and the wireless charging station 20-2 are the first wireless charging station.

S803: the management server 40 obtains charging transmission parameters that meet the target charging standard in the at least one first wireless charging station, respectively. As in the above example, the wireless charging station 20-1 and the wireless charging station 20-2 are first wireless charging stations, the management server 40 can acquire the charging transmission parameters of the wireless charging station 20-1 and the wireless charging station 20-2.

In one possible implementation, the management server 40 may be pre-cached with charging transmission parameters of each wireless charging station under different charging standards. In this case, the management server 40 may read the charging transmission parameter of the first wireless charging station directly from the cache.

In another possible implementation manner, the management server 40 may also send query information to the first wireless charging station to instruct the first wireless charging station to report its charging transmission parameter corresponding to the target charging standard.

It is understood that if there is no first wireless charging station among the wireless charging stations 20-1 to 20-N capable of supporting the target wireless charging standard, the management server 40 may directly determine that the electric vehicle 10 cannot be charged.

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 may be a first wireless charging station whose charging transmission parameters can be matched to the charging reception 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 reception parameters of the electric vehicle 10, the management server 40 may determine that the wireless charging station 20-1 is the target wireless charging station.

In one possible implementation, after determining the target wireless charging station, the management server 40 may further proceed to S805: sending second indication information to the electric vehicle 10, wherein the second indication information may indicate that the electric vehicle 10 and the target transmitting device perform wireless charging. For example, if the wireless charging station 20-1 is the target wireless charging station, the management server 40 may instruct the electric vehicle 10 to wirelessly charge with the wireless charging station 20-1 through the second instruction information. After receiving the second indication, the electric vehicle 10 can stop above the wireless charging station 20-1, so as to wirelessly charge with the wireless charging station 20-1.

It is understood that the management server 40 may also transmit fourth instruction information to the target wireless charging station (S806), and the fourth instruction information may instruct the target wireless charging station to wirelessly charge the electric vehicle 10. For example, the wireless charging station 20-1 is the target wireless charging station, the management server 40 may send fourth indication information to the wireless charging station 20-1, where the fourth indication information may include identification information of the electric vehicle 10, so that the wireless charging station 20-1 can wirelessly charge the electric vehicle 10 after the electric vehicle 10 stops above the wireless charging station 20-1.

The detailed process of the wireless charging between the electric vehicle 10 and the wireless charging station 20-1 can refer to the prior art, and is not described in detail herein.

Example three: the management server 40 and the first wireless charging apparatus cooperatively perform the interoperation determination

In the embodiment of the present application, the management server 40 may further determine a first wireless charging station, and determine whether the first wireless charging station is interoperable. Illustratively, as shown in fig. 9, the method mainly includes the following steps:

s901: the electric vehicle 10 transmits the reception standard information to the management server 40. For a specific implementation manner of receiving the standard information, reference may be made to example one, which is not described herein again.

S902: the management server 40 determines at least one first wireless charging station from among the wireless charging stations 20-1 to 20-N according to the reception standard information. S802 may be referred to for a specific implementation of S902, which is not described herein again.

S903: the management server 40 transmits, to the electric vehicle 10, fifth instruction information that can instruct the electric vehicle 10 of the at least one first wireless charging station. For example, if the wireless charging station 20-1 and the wireless charging station 20-2 are the first wireless charging station, the management server 40 may indicate the wireless charging station 20-1 and the wireless charging station 20-2 to the electric vehicle 10 through the fifth indication information.

S904: the electric vehicle 10 transmits the reception standard information and the reception parameter information to at least one first wireless charging station, respectively. For the specific implementation of the receiving standard information and the receiving parameter information, reference may be made to example one, which is not described in detail herein.

After S904, each first wireless charging station may perform S503 to S508 as shown in fig. 5, thereby completing the interoperation determination. For a specific implementation, reference may be made to example one, which is not described again. The electric vehicle 10 may further determine a target wireless charging station in which the electric vehicle 10 is interoperable, based on the first indication information fed back by the at least one wireless charging station.

Example four: the electric vehicle 10 performs the interoperation determination

The interoperation determination method provided by the embodiment of the application can also be applied to the electric vehicle 10. Illustratively, as shown in fig. 10, the method mainly includes the following steps:

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 may indicate at least one charging standard supported by the wireless charging station 20, and the transmission parameter information may indicate charging transmission parameters corresponding to the at least one charging standard in the wireless charging station 20.

For example, the transmission standard information and the transmission parameter information may be directly sent to the electric vehicle 10 by the wireless charging station 20, or may be sent to other devices by the wireless charging station 20, and then forwarded to the electric vehicle 10 by the other devices, which is not limited in this embodiment of the present invention.

Similar to the specific implementation of the receiving standard information in the first example, the receiving standard information may be carried in a first transmit message, where the first transmit message includes at least one transmitting standard field, and the at least one transmitting standard field corresponds to at least one charging standard one to one. Wherein, the value of each transmission standard field may indicate whether the wireless charging station 20 supports the charging standard corresponding to the transmission standard field. For specific implementation, reference may be made to contents shown in fig. 4 and table 5, which are not described again.

The transmission parameter information may be carried in a second transmission message, which includes at least one transmission function field corresponding to at least one charging transmission parameter, similar to the specific implementation manner of the receiving parameter information in example one. The value of each receiving function field may indicate a value or a value range of a charging transmission parameter corresponding to the receiving function field. The specific implementation of the transmission parameter information may refer to fig. 6 and the content shown in table six, which are not described again.

It should be noted that, unlike example one, the wireless charging station 20 may support a plurality of charging standards, and thus, in example four, the transmission parameter information sent by the wireless charging station 20 may need to indicate a plurality of sets of charging transmission parameters, where each set of charging transmission parameters corresponds to one charging standard.

For example, the wireless charging station 20 supports both the chinese national standard recommendation scheme and the IEC international standard scheme, and the transmission parameter information sent by the wireless charging station 20 may indicate the charging transmission parameters in the wireless charging station 20 that meet the requirements of the chinese national standard recommendation scheme, and may indicate the charging transmission parameters in the wireless charging station 20 that meet the requirements of the IEC international standard scheme.

S1002: the electric vehicle 10 acquires the charging emission parameter that meets the specification of the target charging standard according to the emission parameter information when it is determined that the at least one charging standard includes the target charging standard of the electric vehicle 10 according to the emission standard information.

For example, the wireless charging station 20 supports a chinese national standard recommendation scheme and an IEC international standard scheme, and the target charging standard of the electric vehicle 10 is the chinese national standard recommendation scheme, the electric vehicle 10 may obtain the charging transmission parameter corresponding to the chinese national standard recommendation scheme in the wireless charging station 20 according to the transmission parameter information.

It is understood that if the target charging standard is not included in the charging standards supported by the wireless charging station 20, the electric vehicle 10 may directly determine that the wireless charging station 20 and the electric vehicle 10 are not interoperable. For example, if the wireless charging station 20 supports the chinese international standard recommendation 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 may determine that the wireless charging station 20 and the electric vehicle 10 cannot interoperate with each other.

S1003: the electric vehicle 10 determines whether the wireless charging station 20 and the electric vehicle 10 are interoperable based on the charging transmission parameter complying with the target charging standard and the charging reception parameter complying with the target charging standard in the electric vehicle 10. The specific implementation manner of S1003 is similar to that of S303, and is not described again.

In one possible implementation, after determining whether the wireless charging station 20 and the electric vehicle 10 are interoperable, the electric vehicle 10 may further transmit third indication information to the wireless charging station 20, where the third indication information may indicate whether the wireless charging station 20 and the electric vehicle 10 are interoperable.

If the wireless charging station 20 and the electric vehicle 10 can operate with each other, the electric vehicle 10 can be charged wirelessly with the wireless charging station 20. The specific implementation is not described in detail.
