Description

Charging authentication methods, equipment, systems and media

[0001] This disclosure claims priority to Chinese Patent Application No. 2024110267883, filed on July 29, 2024, entitled "Charging Authentication Method, Device, System and Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of vehicle technology, and more specifically, to a charging authentication method, device, system, and computer-readable storage medium. Background Technology

[0003] With the development of new energy technologies, a large number of electric vehicle users are equipping their vehicles with dedicated charging stations. When charging their electric vehicles through a dedicated charging station, users first control the electric vehicle to enable the charging station to be plugged in, and then insert the charging gun from the charging station into the charging port of the electric vehicle, so that the charging station can charge the electric vehicle.

[0004] However, there is a possibility that user A might control their electric vehicle to make it ready for charging before the designated charging station is even located. This could lead to a situation where, even when a charging station is available, another user B, due to the similarity of the charging stations, might mistakenly insert user A's charging gun into their own electric vehicle's charging port, causing user A's charging station to charge their own vehicle.

[0005] Therefore, identifying whether an electric vehicle and a charging station are compatible is a technical problem that needs to be solved.

[0063] As shown in Figure 1, the charging authentication method provided in this disclosure includes the following steps S11 and S12.

[0064] Step S11: Determine at least one first authentication result based on the hard-wired authentication signal transmitted via the hard-wired connection and / or the wireless authentication signal received via the wireless communication connection.

[0065] The first authentication result is used to characterize whether the target charging device to be authenticated is the second charging device.

[0066] In addition, based on the above step S11, this disclosure also provides another charging authentication method, applied to the charging device to be authenticated, including the following step S21.

[0067] Step S21: Establish a wireless communication connection and / or a hardwired connection with the first charging device;

[0068] Wherein, the hard-wired connection is used to transmit the hard-wired authentication signal, the wireless communication connection is used to send the wireless authentication signal, the hard-wired authentication signal and / or the wireless authentication signal are used to determine at least one first authentication result, at least one first authentication result is used to determine a second authentication result, the first authentication result is used to characterize whether the target charging device to be authenticated is the second charging device, the target charging device to be authenticated is the charging device to be authenticated that is hard-wired connected to the first charging device, and the second charging device is the authenticated charging device of the first charging device.

[0069] It should be noted that the relevant explanations for step S21 above can be found in the relevant explanations for steps S11 and S12 below.

[0070] In this embodiment, hardwired connection refers to a physical connection based on a charging cable.

[0071] A hard-wired authentication signal is a signal used to authenticate the target charging device via a hard-wired connection. Taking a vehicle charging station as an example, the hard-wired authentication signal is a signal transmitted through the charging gun on the charging station to authenticate the target charging device.

[0072] Wireless authentication signals refer to signals received through wireless communication connections used to authenticate the target charging device to be authenticated.

[0073] At any given time, there is at least one charging device awaiting authentication from the first charging device. The charging device that is hardwired to the first charging device is designated as the target charging device awaiting authentication.

[0074] Furthermore, the first charging device has a pre-certified charging device, i.e., a certified charging device. This certified charging device is referred to as the second charging device.

[0075] In this embodiment, at least one first authentication result characterizing whether the target charging device to be authenticated is a second charging device can be determined by at least one of the following four methods based on at least one of the hard-wired authentication signal transmitted via hard-wired connection and the wireless authentication signal received via wireless communication connection.

[0076] The above step S11 is achieved through the following steps S111-1 and S111-2.

[0077] Step S111-1: Obtain the second hardwired connection duration of the second charging device through wireless communication connection.

[0078] Corresponding to step S111-1 above, the charging authentication method for a charging device to be authenticated provided in this disclosure includes the following step S22.

[0079] Step S22: If the charging device to be authenticated is the second charging device, a second hardwired connection duration is sent to the first charging device based on the wireless communication connection, and the second charging device is the authenticated charging device of the first charging device.

[0080] In this embodiment, the first authentication result is determined specifically based on the wireless authentication signal received via the wireless communication connection. The wireless authentication signal is the second hardwired connection duration of the second charging device. Furthermore, the second charging device has been pre-connected to the first charging device and has been authenticated by the first charging device.

[0081] In one embodiment, prior to step S111-1, a process for determining a second charging device is included. This process can specifically involve: the second charging device establishing a communication connection with the first charging device as a charging device to be authenticated; the second charging device sending identity information to be verified to the first charging device based on the communication connection, the identity information to be verified including but not limited to the device identifier of the second charging device and the device identifier of the first charging device pre-authenticated by the second charging device; the first charging device receiving the identity information to be verified based on the aforementioned communication connection, and having pre-stored the authentication identity information of the authenticated charging devices it has authenticated; if the first charging device determines that the identity information to be verified received through the aforementioned communication connection is consistent with the authentication identity information, then it determines that the charging device sending the identity information to be authenticated is the second charging device.

[0082] Step S111-2: If the time difference between the first hard-wire connection duration and the second hard-wire connection duration of the first charging device is less than or equal to a preset duration, the first authentication result is determined to be the target charging device to be authenticated as the second charging device.

[0083] The preset duration is the maximum time difference between the first hardwire connection duration and the second hardwire connection duration when the first charging device charges the second charging device. It can be set based on experience.

[0084] In this embodiment, if the duration of the first hardwired connection of the first charging device and the duration of the hardwired connection of the second charging device exceed a preset duration, it indicates that although the second charging device has established a wireless communication connection with the first charging device, a hardwired connection has not been established between the first and second charging devices. That is, the first charging device and the second charging device have not established a hardwired connection, and the target charging device to be authenticated that is hardwired to the first charging device is not the second charging device. In this case, the first authentication result is determined to be that the target charging device to be authenticated is not the second charging device.

[0085] Conversely, if the duration of the first hardwired connection of the first charging device and the duration of the hardwired connection of the second charging device are less than or equal to a preset duration, it indicates that the second charging device has established both a wireless communication connection and a hardwired connection with the first charging device. That is, charging occurs between the first and second charging devices, and the target charging device to be authenticated that is hardwired to the first charging device is the second charging device. In this case, the first authentication result is determined to be the second charging device.

[0086] The above step S11 is achieved through the following steps S112-1 and S112-2.

[0087] Step S112-1: Send the first hardwire authentication signal to the target charging device to be authenticated via hardwire connection.

[0088] Corresponding to step S112-1 above, the charging authentication method for a charging device to be authenticated provided in this disclosure includes the following steps S22 and S23.

[0089] Step S22: When the charging device to be authenticated is hardwired to the first charging device, the charging device to be authenticated is determined to be the target charging device to be authenticated.

[0090] Step S23: Receive the first hardwire authentication signal sent by the first charging device based on the hardwire connection.

[0091] In this embodiment, the first authentication result is determined specifically based on the hard-wired authentication signal transmitted via the hard-wired connection and the wireless authentication signal received via the wireless communication connection. Specifically, the hard-wired authentication signal transmitted via the hard-wired connection is the first hard-wired authentication signal sent by the first charging device to the target charging device to be authenticated, and the wireless authentication signal is the wireless communication information received via the wireless communication connection.

[0092] In one embodiment, the first hard-wired authentication signal is a signal with a specific waveform. Correspondingly, the correct parameter values ​​of the first hard-wired authentication signal are its amplitude, frequency, phase, duty cycle, etc.

[0093] It should be noted that, in this embodiment, when the target charging device to be authenticated receives the first hardwired authentication signal, if the target charging device to be authenticated is in a communicative connection with the first charging device, the target charging device to be authenticated identifies the correct parameters of the first hardwired authentication signal, encapsulates the identified correct parameters of the first hardwired authentication signal with its own device identifier to obtain wireless communication information, and sends this wireless communication information to the first charging device based on the wireless communication connection. If the target charging device to be authenticated is not in a communicative connection with the first charging device, even if it identifies the correct parameters of the first hardwired authentication signal and encapsulates the identified first hardwired authentication signal with its own device identifier to obtain wireless communication information, it will still be unable to send this wireless communication information to the first charging device based on the wireless communication connection.

[0094] Step S112-2: If the correct parameter value for the first hard-wired authentication signal is received from the second charging device via wireless communication within a preset time period, the first authentication result is determined to be the second charging device as the target charging device to be authenticated.

[0095] Corresponding to step S112-2 above, the charging authentication method for a charging device to be authenticated provided in this disclosure further includes the following steps S24 and S25, based on steps S22 and S23 above.

[0096] Step S24: Generate a wireless authentication signal based on the first hard-wired authentication signal. The wireless authentication signal includes the correct parameters of the first hard-wired authentication signal and the device identifier of the charging device to be authenticated.

[0097] Step S25: When the target charging device to be authenticated is wirelessly connected to the first charging device, a wireless authentication signal is sent to the first charging device.

[0098] In this disclosure, the preset time period is a fixed duration starting from the moment when the first charging device sends the first hardwired authentication signal to the target charging device to be authenticated. This fixed duration is the maximum duration required for the second charging device to reply with the correct parameter value for the first hardwired authentication signal to the first charging device via wireless communication when the first charging device and the second charging device are hardwired connected.

[0099] The first charging device sends a first hardwired authentication signal to the target charging device to be authenticated via a hardwired connection. Further, the first charging device checks whether it has received the correct parameter values ​​for the first hardwired authentication signal from the second charging device via a wireless communication connection within a preset time period.

[0100] Specifically, the method by which the first charging device detects whether it has received the correct parameter value for the first hard-wire authentication signal sent by the second charging device via the wireless communication connection within a preset time period can be as follows: It detects whether wireless communication information has been received via the wireless communication connection within the preset time period; if no wireless communication information is received, it determines that the first charging device has not received the correct parameter value for the first hard-wire authentication signal sent by the second charging device via the wireless communication connection within the preset time period; if wireless communication information is received, it determines whether the device identifier of the transmitting device included in the wireless communication information is the device identifier of the second charging device; if the device identifier of the transmitting device included in the wireless communication information is not the device identifier of the second charging device... If the device is identified as a second charging device, it is determined that the first charging device did not receive the correct parameter value for the first hard-wired authentication signal sent by the second charging device via wireless communication within a preset time period. If the device is identified as a second charging device, it is determined whether the wireless communication information contains the correct parameter information for the first hard-wired authentication signal. If the wireless communication information contains the correct parameter information for the first hard-wired authentication signal, it is determined that the first charging device received the correct parameter value for the first hard-wired authentication signal sent by the second charging device via wireless communication within a preset time period; otherwise, it is determined that the first charging device did not receive the correct parameter value for the first hard-wired authentication signal sent by the second charging device via wireless communication within a preset time period.

[0101] Furthermore, if the correct parameter value for the first hardwired authentication signal sent by the second charging device is not received via wireless communication within the preset time period, it indicates that the second charging device has not received the first hardwired authentication signal sent by the first charging device. That is, the second charging device is not hardwired connected to the first charging device, and the target charging device to be authenticated that is hardwired to the first charging device is not the second charging device. In this case, the first authentication result is determined to be that the target charging device to be authenticated is not the second charging device.

[0102] Conversely, if the correct parameter value for the first hardwire authentication signal is received from the second charging device within a preset time period, it indicates that the second charging device has received the first hardwire authentication signal sent by the first charging device. This means the second charging device is hardwired to the first charging device, and the target charging device to be authenticated that is hardwired to the first charging device is the second charging device. In this case, the first authentication result is determined to be the second charging device.

[0103] In one embodiment of this disclosure, the first charging device is a charging pile, and the first hard-wired authentication signal is a first PWM signal output via the CP pin of the charging gun of the charging pile. The correct parameter values ​​of the first hard-wired authentication signal are the frequency and duty cycle of the first PWM signal. Alternatively, the first charging device is a vehicle, and the first hard-wired authentication signal is a second PWM signal formed by the on / off switching of a control guide switch inside the vehicle. The correct parameter information of the first hard-wired authentication signal is the frequency and duty cycle of the second PWM signal. In this embodiment, no hardware modification to the first charging device is required; the first charging device can transmit the first hard-wired authentication signal, which reduces the hardware cost of the charging authentication method provided in this disclosure.

[0104] The above step S11 is achieved through the following steps S113-1 to S113-4.

[0105] Step S113-1: Receive the second hardwire authentication signal sent by the target charging device to be authenticated via hardwire connection.

[0106] Corresponding to step S113-1 above, the charging authentication method for a charging device to be authenticated provided in this disclosure further includes the following steps S26 and S27.

[0107] Step S26: When the charging device to be authenticated is hardwired to the first charging device, the charging device to be authenticated is determined to be the target charging device to be authenticated.

[0108] Step S27: Send a second hardwire authentication signal to the first charging device.

[0109] In this embodiment, the first authentication result is determined specifically based on the hard-wired authentication signal transmitted via a hard-wired connection and the wireless authentication signal received via a wireless communication connection. The hard-wired authentication signal transmitted via the hard-wired connection is the second hard-wired authentication signal sent by the target charging device to the first charging device. The wireless authentication signal is authentication verification information sent by the charging device to be authenticated, including the device identifier of the charging device to be authenticated and the correct parameter values ​​of the second hard-wired authentication signal it can send.

[0110] Furthermore, if the target charging device to be authenticated is hardwired to the first charging device, a second hardwired authentication signal is sent to the first charging device via the hardwired connection. The descriptions of the second hardwired authentication signal and the correct parameter values ​​of the second hardwired authentication signal are the same as those of the first hardwired authentication signal, and will not be repeated here.

[0111] Step S113-2: Determine the value of the parameter to be authenticated for the second hard-wire authentication signal based on the second hard-wire authentication signal.

[0112] In this embodiment, the first charging device performs feature recognition on the second hard-wire authentication signal to obtain the feature value corresponding to the second hard-wire authentication signal. The identified feature value corresponding to the second hard-wire authentication signal is recorded as the authentication parameter value.

[0113] Step S113-3: Receive authentication verification information sent by the charging device to be authenticated via wireless communication connection, and obtain target authentication verification information that matches the parameter value to be authenticated from the authentication verification information.

[0114] Corresponding to steps S113-3 above, the charging authentication method for a charging device to be authenticated provided in this disclosure further includes the following step S28, based on steps S26 and S27 above.

[0115] Step S28: When the target charging device to be authenticated is wirelessly connected to the first charging device, authentication verification information is sent to the first charging device based on the wireless communication connection. The authentication verification information includes the device identifier of the target charging device to be authenticated and the correct parameter value of the second hard-wired authentication signal.

[0116] In this embodiment, when the charging device to be authenticated establishes a communication connection with the first charging device, it sends authentication verification information to the first charging device based on the wireless communication connection. This authentication verification information includes the device identifier of the charging device to be authenticated and the correct parameter values ​​of the second hard-wired authentication signal it can send.

[0117] Furthermore, when the first charging device receives at least one authentication verification message based on the wireless communication connection, it searches for authentication verification messages from the authentication verification messages that correspond to the correct parameter value that is the same as the parameter value to be authenticated determined in step S113-2 above, and uses it as the target authentication verification message that matches the parameter value to be authenticated.

[0118] Step S113-4: If the device identifier in the target authentication verification information is the device identifier of the second charging device, determine that the target charging device to be authenticated is the second charging device.

[0119] In this embodiment, the first charging device pre-stores the device identifier of the second charging device. The first charging device verifies whether the device identifier in the target authentication verification information is the device identifier of the second charging device. If the device identifier in the target authentication verification information is verified to be the device identifier of the second charging device, it indicates that the second hardwired authentication signal is sent by the second charging device through a hardwired connection. That is, the target charging device to be authenticated that is hardwired to the first charging device is the second charging device. At this time, the first authentication result is determined to be that the target charging device to be authenticated is the second charging device.

[0120] Conversely, if the device identifier in the target authentication verification information is not the device identifier of the second charging device, it indicates that the second hardwired authentication signal was not sent by the second charging device via a hardwired connection. That is, the target charging device to be authenticated, which is hardwired to the first charging device, is not the second charging device. In this case, the first authentication result is determined to be that the target charging device to be authenticated is not the second charging device.

[0121] In one embodiment of this disclosure, the first charging device is a charging pile, the charging device to be authenticated is a vehicle, and the second hard-wired authentication signal is a third PWM signal generated by the on / off switching of a control guide switch inside the vehicle. The authentication verification information includes the frequency and duty cycle of the third PWM signal and the VIN of the charging device to be authenticated. Alternatively, the first charging device is a vehicle, the charging device to be authenticated is a charging pile, and the second hard-wired authentication signal is a fourth PWM signal output from the CP pin of the charging gun of the charging pile. The authentication verification information includes the frequency and duty cycle of the fourth PWM signal and the VIN of the charging device to be authenticated. In this embodiment, no hardware modification is required for the target charging device to be authenticated to transmit the second hard-wired authentication signal.

[0122] Step S11 above specifically determines the first authentication result based on the hardwire authentication signal transmitted via the hardwire connection. Specifically, the first charging device, via the hardwire connection, instructs the target charging device to be authenticated to transmit a fifth hardwire authentication signal via the hardwire connection; the first charging device receives the fifth hardwire authentication signal via the hardwire connection, and authenticates the fifth hardwire authentication signal to determine whether the parameter value of the fifth hardwire authentication signal is the same as the parameter value of the hardwire authentication signal that the second charging device can send; if yes, the first authentication result is determined to be that the target charging device to be authenticated is the second charging device; if no, the first authentication result is determined to be that the target charging device to be authenticated is not the second charging device.

[0123] Step S12: Determine the second authentication result based on at least one first authentication result.

[0124] In this embodiment, step S11 is implemented using at least one of the four methods described above. Based on this, at least one first authentication result can be obtained from step S11. The second authentication result is the final authentication result obtained based on at least one first authentication result.

[0125] In one embodiment, if at least one first authentication result indicates that the target charging device to be authenticated is the second charging device, then the second authentication result is determined to be the target charging device to be authenticated as the second charging device.

[0126] In another embodiment, if there are three first authentication results, and at least two of the first authentication results indicate that the target charging device to be authenticated is the second charging device, then the second authentication result is determined to be that the target charging device to be authenticated is the second charging device.

[0127] It should be noted that the determination method in step S12 above can be determined according to the requirements.

[0128] The second authentication result determined in step S12 above can then determine whether the target charging device to be authenticated, which is hardwired to the first charging device, is the second charging device. Thus, when the first charging device is a charging pile and the target charging device to be authenticated is a vehicle, it can be identified whether the charging pile is hardwired to an authenticated vehicle. When the first charging device is a vehicle and the target charging device to be authenticated is a charging pile, it can be identified whether the vehicle is hardwired to an authenticated charging pile. In other words, it can be determined whether the vehicle and the charging pile are identical.

[0129] In one embodiment of this disclosure, the charging authentication method provided in this disclosure may further include the following step S13.

[0130] Step S13: If the second authentication result indicates that the target charging device to be authenticated is not the second charging device, control the first charging device to stop charging.

[0131] In this embodiment, based on the above step S13, the problem of the first charging device continuing to incorrectly charge the target charging device that is not the second charging device can be avoided.

[0132] This disclosure provides a charging authentication method applied to a first charging device, comprising: determining at least one first authentication result based on a hard-wired authentication signal transmitted via a hard-wired connection and / or a wireless authentication signal received via a wireless communication connection; and determining a second authentication result based on the at least one first authentication result. The first authentication result is used to characterize whether the target charging device to be authenticated is a second charging device, wherein the target charging device to be authenticated is a charging device to be authenticated that is hard-wired to the first charging device, and the second charging device is an authenticated charging device of the first charging device. Using this method, when the first charging device is a charging pile and the target charging device to be authenticated is a vehicle, it can identify whether the charging pile is hard-wired to an authenticated vehicle. When the first charging device is a vehicle and the target charging device to be authenticated is a charging pile, it can identify whether the vehicle is hard-wired to an authenticated charging pile. In other words, it can identify whether the vehicle and the charging pile are identical.

[0133] In one embodiment of this disclosure, the charging authentication method provided by this disclosure further includes the following steps S114-1 to S114-4 before the above step S11.

[0134] Step S114-1: Establish a wireless communication connection with the charging device to be authenticated.

[0135] Step S114-2: Receive the basic information to be verified sent by the charging device to be authenticated via wireless communication connection.

[0136] Corresponding to step S114-2 above, the charging authentication method for a charging device to be authenticated provided in this disclosure further includes the following step S29.

[0137] Step S29: Send the basic information to be verified to the first charging device via wireless communication connection.

[0138] Step S114-3: If the preset authentication basic information matches the basic information to be verified, determine that the charging device to be authenticated is the second charging device.

[0139] Step S114-4 involves controlling the first charging device to be in a rechargeable state and triggering a step of determining at least one first authentication result based on a hard-wired authentication signal transmitted via a hard-wired connection and / or a wireless authentication signal received via a wireless communication connection.

[0140] In one embodiment, the basic information to be verified may specifically be: the device identifier of the charging device to be authenticated. Furthermore, the preset authentication basic information may specifically be the device identifier of the second charging device.

[0141] If the basic information to be verified matches the preset authentication basic information, it is determined that one of the charging devices wirelessly connected to the first charging device is the second charging device. At this point, it is determined that the second charging device has a charging requirement. Based on this, the first charging device is controlled to be in a charging-ready state. However, if a situation occurs where a non-second charging device is hardwired to the first charging device, step S11 is triggered to identify this situation.

[0142] Conversely, if the basic information to be verified is inconsistent with the preset authentication basic information, it is determined that the second charging device has no charging requirement. In this case, the first charging device is controlled to be in an uncharging state, and the step of determining at least one first authentication result based on the hard-wired authentication signal transmitted via the hard-wired connection and / or the wireless authentication signal received via the wireless communication connection is not triggered to authenticate the target charging device to be authenticated. In this way, unnecessary computational resource overhead for the first charging device can be avoided.
