[0001] This invention relates to the field of charging technology, and more specifically, to a charging control method and device. Background Technology

[0002] With the rapid development of new energy technologies, the demand for improving the vehicle charging experience is increasing.

[0003] Currently, vehicle charging experiences all utilize a seamless charging method, which involves identifying the charging equipment and the vehicle being charged to release charging authority to the vehicle. In other words, seamless charging primarily addresses the issue of the charging equipment relinquishing charging authority to the vehicle being charged.

[0004] However, it is impossible to guarantee whether the vehicle to be charged is the target vehicle that has completed the charging permission authentication. This poses a risk of unauthorized charging by the charging equipment. At the same time, for users, the failure of the charging equipment to authenticate the charging permission of the vehicle to be charged can lead to charging accidents, causing certain safety hazards and economic losses.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0055] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0056] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0057] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0058] To better understand the charging control method and device provided in the embodiments of this application, the charging device of the embodiments of this application will be described in detail with reference to the accompanying drawings and through multiple embodiments. Figure 1 This is a schematic diagram of a charging device provided in an embodiment of this application. Figure 1 As shown, the charging device 100 includes: a charging control device 110, a wireless communication module 120, a power module 130, and a charging gun 140.

[0059] The power module 130's output terminal is connected to the power line of the charging gun 140, providing the charging gun 140 with an electrical signal for normal operation. The power module 130's control terminal is also connected to the charging control device 110, allowing the charging control device 110 to control the power module 130's output, thereby controlling the charging gun 140. The charging gun 140 is used to connect to a vehicle to be charged, so that when the vehicle is connected to the charging device 100, the charging gun 140 in the charging device 100 can charge the vehicle. The charging control device 110 is also connected to the charging gun 140. A signal line connection is provided to transmit the charging data signal from the charging gun 140 charging the vehicle to be charged to the charging control device 110 in real time for subsequent analysis. The charging control device 110 is also connected to the wireless communication module 120 to enable the charging control device 110 to connect with other devices that require wireless connection through the wireless communication module 120. For example, the charging control device 110 can wirelessly connect with the vehicle to be charged through the wireless communication module 120 to achieve a communication connection with the vehicle to be charged for subsequent processing. The charging control device 110 can be used to implement charging control methods.

[0060] The charging control method provided in this application can be executed by a charging control device integrated in the charging device. The charging control method provided in the above-mentioned embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 2 A flowchart illustrating a charging control method provided in this application embodiment. Figure 1 This method is applied to charging devices, such as... Figure 2 As shown, the method may include:

[0061] S210, Obtain the first time parameters of the charging device detection.

[0062] Specifically, when a user inserts the charging gun of the charging device into the vehicle to be charged, the charging device and the vehicle to be charged start timing in seconds, and the charging device can send the first time parameter information it detects to the charging device.

[0063] S220: Receives second time parameters sent by the vehicle to be charged, which is wirelessly connected to the charging equipment.

[0064] Specifically, the charging device and the vehicle to be charged are connected wirelessly, allowing the vehicle to transmit its detected second-time parameter information to the charging device. The wireless connection method can be selected based on the specific situation; for example, it can be Wi-Fi (Wireless-Fidelity), Bluetooth, ZigBee (ZigBee Technology), or NFC (Near Field Communication).

[0065] S230. Determine the charging permission status of the vehicle to be charged based on the first time parameter and the second time parameter.

[0066] Specifically, based on the first and second time parameters obtained simultaneously in the above steps, the matching result of the first and second time parameters can be used to determine whether the target charging vehicle is a vehicle to be charged connected to the charging equipment. When the target charging vehicle is determined to be a vehicle to be charged connected to the charging equipment, the charging permission status of the target charging vehicle can be determined, that is, the charging permission status of the vehicle to be charged wirelessly connected to the charging equipment can be determined, so as to ensure effective charging of the vehicle to be charged and the charging equipment, thereby avoiding the safety hazard caused by the vehicle to be charged and the vehicle to be charged wirelessly connected to the charging equipment not being the same vehicle.

[0067] It should be noted that the first time parameter in the above embodiment is detected and obtained by the charging device; the second time parameter is detected and obtained by the vehicle to be charged that is wirelessly connected to the charging device and then sent to the charging device.

[0068] Embodiments of the present invention provide a charging control method that acquires first time parameters detected by a charging device and receives second time parameters sent by a vehicle to be charged that is wirelessly connected to the charging device. Based on the first and second time parameters, the charging permission status of the vehicle to be charged is determined. Therefore, this application can determine the charging permission status of the vehicle to be charged based on the first time parameters detected by the charging device itself and the second time parameters received from the vehicle to be charged that is wirelessly connected to the charging device. This ensures effective charging between the vehicle to be charged and the charging device, thereby preventing situations where the vehicle being charged and the vehicle wirelessly connected to the charging device are not the same vehicle, thus avoiding economic losses for the user and safety hazards caused by the vehicle being charged and the vehicle wirelessly connected to the charging device not being the same vehicle.

[0069] As an optional implementation, this application also provides a possible method for determining the charging permission status of a vehicle to be charged. The first time parameter includes a first insertion duration; the second time parameter includes a second insertion duration.

[0070] The first insertion duration refers to the first time parameter information detected by the charging device when the vehicle to be charged is inserted into the charging device; the second insertion duration refers to the time parameter information detected and obtained by the vehicle to be charged when the charging component (e.g., the charging gun) of the charging device is inserted into the vehicle to be charged. The second time parameter is sent by the vehicle to be charged to the charging device, and the charging device matches it with the first insertion duration after receiving it.

[0071] It should be noted that when the vehicle to be charged is plugged into the charging device, the vehicle to be charged and the charging device start timing simultaneously using the same base time unit, for example, simultaneously in seconds, or other counting methods.

[0072] To further illustrate the charging control method provided in the embodiments of this application. Figure 3 This is a schematic diagram of a charging control guide circuit provided in an embodiment of this application. Figure 3 As shown, when the user does not insert the charging gun of the charging device into the vehicle to be charged, the switch S1 in the charging device is in the 12V position of the power supply control device, and the internal resistor R1 of the charging device does not form a circuit loop with the grounding point (vehicle ground). At this time, the voltages across the internal resistor R1 are equal, that is, the voltage at detection point 1 of the charging device is 12V, and the voltage at detection point 2 of the vehicle to be charged is 0V.

[0073] Furthermore, as shown above, determining the charging permission status of the vehicle to be charged based on the first time parameter and the second time parameter may include:

[0074] If the duration of the first charging gun insertion and the duration of the second charging gun insertion match, then the first charging permission status of the vehicle to be charged is determined to include: releasing charging permission to the vehicle to be charged.

[0075] Continue to refer to Figure 3When a user inserts the charging gun of the charging device into the vehicle to be charged, switch S1 in the charging device is initially in the 12V position of the power supply control device, while switch S2 in the vehicle to be charged is in the off state. Further, the charging device can compare the first insertion duration it detects with the second insertion duration received from the vehicle to be charged. If the first and second insertion durations match, indicating that the target vehicle is wirelessly connected to the charging device, the charging device can grant charging permission to the vehicle. At this time, switch S1 of the charging device can switch to the PWM position. That is, when the first and second insertion durations match, the first charging permission state of the vehicle to be charged is granting charging permission to the vehicle.

[0076] If the duration of the first charging gun insertion and the duration of the second charging gun insertion do not match, the second charging permission status of the vehicle to be charged is determined to include: refusing to release charging permission to the vehicle to be charged.

[0077] Optionally, if the first and second plug-in durations do not match, meaning the charging device can receive the second plug-in duration sent from the vehicle to be charged and its own detected first plug-in duration, but the acquired first plug-in duration and the received second plug-in duration do not match, indicating the target charging vehicle is not the vehicle to be charged wirelessly connected to the charging device, the wireless connection between the charging device and the vehicle to be charged is disconnected. In other words, the charging device refuses to grant charging permission to the vehicle to be charged. Specifically, when the first and second plug-in durations do not match, the second charging permission status for the vehicle to be charged is "refuse to grant charging permission to the vehicle to be charged."

[0078] For example, in Figure 3 Based on this, when a user inserts the charging gun of the charging device into the vehicle to be charged, the system obtains the first insertion duration detected by the charging device and receives the second insertion duration sent by the vehicle to be charged, which is wirelessly connected to the charging device. Then, based on the first and second insertion durations, it can be determined whether the target vehicle is the same vehicle wirelessly connected to the charging device. When the target vehicle is determined to be the same vehicle, its charging permission status can be determined to ensure effective charging between the vehicle and the charging device. This avoids situations where the vehicle being charged and the vehicle wirelessly connected to the charging device are not the same vehicle, thus preventing economic losses for the user and avoiding safety hazards caused by the vehicle being charged and the vehicle wirelessly connected to the charging device being different vehicles.

[0079] As an optional implementation, this application, based on the above embodiments, also provides a possible method for determining the charging permission status of a vehicle to be charged. The first time parameter may include: a first closing duration; wherein the first closing duration is the time parameter information obtained by the charging device after the charging connection line between the vehicle to be charged and the charging device is closed; the second time parameter may include: a second closing duration; wherein the second closing duration is the time parameter information obtained by the vehicle to be charged after the charging connection line between the vehicle to be charged and the charging device is closed. The first charging permission status, as shown above, includes releasing charging permission to the vehicle to be charged; the method may further include:

[0080] If the first closing duration and the second closing duration match, the first charging permission status of the vehicle to be charged also includes: allowing the vehicle to be charged to be charged.

[0081] When the switch S2 of the vehicle to be charged begins to close, both the charging device and the vehicle to be charged begin timing in seconds. The charging device can send the first closing duration information it detects to the charging device. Since the charging device and the vehicle to be charged are connected wirelessly, when the vehicle to be charged detects its second closing duration, it sends it to the charging device wirelessly, so that the charging device receives the second closing duration sent by the vehicle to be charged.

[0082] Optionally, the charging device will detect a first closing duration and receive a second closing duration from the vehicle to be charged. If the first closing duration and the second closing duration match, that is, the vehicle to be charged and the target vehicle are the same vehicle, that is, the target vehicle is the vehicle to be charged that is wirelessly connected to the charging device, and the charging device has released the charging permission, the charging device can charge the vehicle to be charged. That is, when the first closing duration and the second closing duration match, the first charging permission status of the vehicle to be charged is that the vehicle to be charged is allowed to be charged.

[0083] If the first closing duration and the second closing duration do not match, the second charging permission status of the vehicle to be charged is determined to include: revoking the charging permission of the vehicle to be charged.

[0084] Optionally, if the first closing duration and the second closing duration do not match, meaning the charging device can receive the second closing duration sent from the vehicle to be charged and the first closing duration it detects, but the acquired first closing duration and the received second closing duration do not match, meaning the target charging vehicle is not the vehicle to be charged wirelessly connected to the charging device, and the charging device releases charging permission to the vehicle to be charged when the first plug-in duration and the second plug-in duration match, the charging device can revoke the charging permission of the vehicle to be charged because the first closing duration and the second closing duration do not match. That is, when the first closing duration and the second closing duration do not match, the second charging permission status of the vehicle to be charged is revoked.

[0085] The charging control method provided in the embodiments of the present invention, if the first closing duration and the second closing duration match, further includes determining the first charging permission state of the vehicle to be charged as: allowing the vehicle to be charged to be charged; if the first closing duration and the second closing duration do not match, determining the second charging permission state of the vehicle to be charged includes: revoking the charging permission of the vehicle to be charged. Therefore, based on the matching of the first plug-in duration and the second plug-in duration, the present application, after the charging device obtains its own detected first closing duration and receives the second closing duration sent from the vehicle to be charged, determines whether the first closing duration and the second closing duration match, and based on the matching result of the first closing duration and the second closing duration, ensures effective charging between the vehicle to be charged and the charging device, thereby preventing the vehicle being charged from being the same vehicle as the vehicle wirelessly connected to the charging device, i.e., confirming that the vehicle wirelessly connected to the charging device is the target charging vehicle, thus avoiding economic losses for the user and avoiding safety hazards caused by the vehicle being charged and the vehicle wirelessly connected to the charging device not being the same vehicle.

[0086] As an optional implementation, this application, based on the above embodiments, also provides a possible method for determining the charging permission status of a vehicle to be charged. The first time parameter may include: a first closing duration; wherein the first closing duration is the time parameter information obtained by the charging device after the charging connection line between the vehicle to be charged and the charging device is closed; the second time parameter may include: a second closing duration; wherein the second closing duration is the time parameter information obtained by the vehicle to be charged after the charging connection line between the vehicle to be charged and the charging device is closed.

[0087] As shown above, determining the charging permission status of the vehicle to be charged based on the first and second time parameters can include:

[0088] If the first closing duration and the second closing duration match, the first charging permission status of the vehicle to be charged is determined to include: releasing the charging permission to the vehicle to be charged and allowing the vehicle to be charged to be charged.

[0089] Continue to refer to Figure 3 When the detection point 2 of the vehicle to be charged detects the transmitted PWM waveform, the switch S2 of the vehicle to be charged begins to close. The charging device acquires the first closing duration detected by itself and the second closing duration sent by the vehicle to be charged that is wirelessly connected to the charging device. When it is determined that the first closing duration and the second closing duration match, that is, the vehicle to be charged and the target charging vehicle are the same vehicle, that is, the target charging vehicle is the vehicle to be charged that is wirelessly connected to the charging device, and the charging device can release charging permission to the vehicle to be charged that is wirelessly connected to it and allow charging to the vehicle to be charged, that is, when the first closing duration and the second closing duration match, the first charging permission state of the vehicle to be charged is to release charging permission to the vehicle to be charged and allow charging to the vehicle to be charged.

[0090] If the first closing duration and the second closing duration do not match, the second charging permission status of the vehicle to be charged is determined to include: refusing to release charging permission to the vehicle to be charged.

[0091] Optionally, if the first closing duration and the second closing duration do not match, that is, the charging device can receive the second closing duration sent from the vehicle to be charged and the first closing duration detected by itself, but the acquired first closing duration and the received second closing duration do not match, that is, the target charging vehicle is not the vehicle to be charged that is wirelessly connected to the charging device, the charging device refuses to release charging permission to the vehicle to be charged. In other words, when the first closing duration and the second closing duration do not match, the second charging permission status of the vehicle to be charged is "refuse to release charging permission to the vehicle to be charged".

[0092] As an optional implementation, the charging control method shown above may further include:

[0093] The first time parameter and the second time parameter are determined based on the voltage value of the target detection point on the charging connection line between the vehicle to be charged and the charging equipment.

[0094] In one possible implementation, continue to refer to Figure 3When a user inserts the charging gun of the charging device into the vehicle to be charged, the switch S1 in the charging device is initially in the 12V position of the power supply control device. Since the switch S2 in the vehicle to be charged is in the open state, the internal resistor R1 of the charging device is connected in series with the resistor R3 of the vehicle to be charged. This series circuit forms a circuit loop with the grounding point (vehicle ground). Due to the series connection of the internal resistor R1 and the resistor R3, the voltage of the charging control guide circuit is divided, so that the voltage of detection point 1 of the charging device is 9V and the voltage of detection point 2 of the vehicle to be charged is 9V. That is, the voltage value of the target detection point on the charging connection line between the vehicle to be charged and the charging device is 9V. Based on the time parameter information that the voltage of detection point 1 of the charging device is 9V, the first time parameter of the charging device, such as the first insertion time, can be obtained; and based on the time parameter information that the voltage of detection point 2 of the vehicle to be charged is 9V, the second time parameter of the vehicle to be charged, such as the second insertion time, can be obtained.

[0095] It should be noted that the internal resistors R1 and R3 are connected in series to divide the voltage in the charging control guide circuit. The voltage division is related to the resistance values ​​of the resistors.

[0096] In another possible implementation, continue to refer to Figure 3 When the duration of the first and second charging gun insertions matches, i.e., when the switch S1 of the charging device is in the PWM position and the voltage at the PWM position in the charging device is 9V, the charging device releases charging permission to the vehicle to be charged. Figure 2 Based on this, when the detection point 2 of the vehicle to be charged detects the transmitted PWM waveform, the switch S2 of the vehicle to be charged begins to close. When the switch S2 of the vehicle to be charged is closed, resistors R2 and R3 are connected in parallel, and the parallel R2 and R3 are connected in series with the internal resistor R1 of the charging device to divide the voltage of the charging control guide circuit. This allows both the detection point 1 of the charging device and the detection point 2 of the vehicle to be charged to detect the PWM waveform, and the voltage is 6V. Therefore, based on the time parameter information that the voltage of the detection point 1 of the charging device is 6V, the first time parameter of the charging device, such as the first closing duration, can be obtained; and based on the time parameter information that the voltage of the detection point 2 of the vehicle to be charged is 6V, the second time parameter of the vehicle to be charged, such as the second closing duration, can be obtained.

[0097] The first closing time refers to the first closing time parameter detected by the charging device itself when the detection point 2 of the vehicle to be charged detects the transmitted PWM waveform and the switch S2 of the vehicle to be charged begins to close; the second closing time refers to the second closing time received by the charging device from the vehicle to be charged when the detection point 2 of the vehicle to be charged detects the transmitted PWM waveform and the switch S2 of the vehicle to be charged begins to close.

[0098] As an optional implementation method, Figure 4 A flowchart illustrating a charging control method provided in this application embodiment. Figure 2 .like Figure 4 As shown above, before determining the charging permission status of the vehicle to be charged based on the first time parameter and the second time parameter, the method may further include:

[0099] S410. Determine the time error of the first time parameter and the second time parameter.

[0100] Specifically, when the charging device detects its own first time parameter, it also receives a second time parameter detected by the vehicle to be charged, which is wirelessly connected to it. This allows the charging device to determine the time error between the first and second time parameters. The time error can be determined by the time difference between the first and second time parameters.

[0101] S420. If the time error is within the preset error range, then determine that the first time parameter and the second time parameter are matched.

[0102] The preset error range can be selected according to the actual situation. For example, the preset error range can be selected as -3S to 3S.

[0103] Optionally, if the time error between the first time parameter and the second time parameter is within a preset error range (e.g., -3S to 3S), then the first time parameter and the second time parameter are determined to be matched, that is, the target charging vehicle is the vehicle to be charged that is wirelessly connected to the charging device, and the charging device can release charging permission to the vehicle to be charged.

[0104] S430. If the time error is not within the preset error range, then it is determined that the first time parameter and the second time parameter do not match.

[0105] Optionally, if the time error between the first time parameter and the second time parameter is not within the preset error range (e.g., -3S to 3S), then it is determined that the first time parameter and the second time parameter do not match, that is, the target charging vehicle is not the vehicle to be charged that is wirelessly connected to the charging device, and the wireless connection between the charging device and the vehicle to be charged is disconnected, or the charging device refuses to release charging permission to the vehicle to be charged.

[0106] The charging control method provided in the embodiments of the present invention determines the time error between a first time parameter and a second time parameter. If the time error is within a preset error range, the first time parameter and the second time parameter are determined to match; if the time error is not within the preset error range, the first time parameter and the second time parameter are determined to be mismatched. Therefore, by determining the relationship between the time error between the present application and the second time parameter based on the first time parameter, and the preset error range, it is possible to determine whether the target charging vehicle is a vehicle connected to the charging equipment, thereby determining the charging permission status of the vehicle to be charged. This avoids situations where the vehicle being charged and the vehicle wirelessly connected to the charging equipment are not the same vehicle, thus preventing economic losses for the user and avoiding safety hazards caused by the vehicle being charged and the vehicle wirelessly connected to the charging equipment not being the same vehicle.

[0107] As an optional implementation method, Figure 5 A flowchart illustrating a charging control method provided in this application embodiment. Figure 3 .like Figure 5 As shown above, before obtaining the first time parameters detected by the charging device, the method may further include:

[0108] S510: Send authentication information to the vehicle to be charged so that the vehicle to be charged can authenticate the charging device based on the authentication information of the charging device.

[0109] Once a wireless connection is successfully established between the charging device and the vehicle being charged, the charging device sends an identity declaration to the vehicle. The vehicle receives the identity declaration from the charging device, allowing it to verify the charging device based on its authentication information. This authentication information may include details such as the type and manufacturer of the charging device.

[0110] S520. If no verification information is received from the vehicle to be charged within the first preset time period, the identity verification information of the charging device is resent to the vehicle to be charged until the preset first resending condition is met.

[0111] The first retransmission condition is receiving verification information returned by the vehicle to be charged.

[0112] The first preset duration can be selected according to the actual situation. For example, the first preset duration can be selected as 1 second.

[0113] Optionally, the charging device sends authentication information to the vehicle to be charged after a successful wireless connection. However, if it does not receive authentication information from the vehicle to be charged within a first preset time period (e.g., 1 second), it can resend the authentication information to the vehicle to be charged until a preset first retransmission limit is reached, i.e., a pre-set first number of retransmissions, such as 3 times. Alternatively, if authentication information is received from the vehicle to be charged within the preset first retransmission limit (e.g., 3 times), the charging device verifies the authentication information sent by the vehicle and returns the verification result to the vehicle to be charged. This verification information may include information such as vehicle type and manufacturer.

[0114] S530. If the preset second retransmission condition is met within the first preset time period, the wireless connection with the vehicle to be charged is disconnected.

[0115] The second condition for resending is that no verification information from the vehicle to be charged is received, or the identity authentication of the vehicle to be charged fails.

[0116] Optionally, if the authentication information of the vehicle to be charged is not received from the vehicle to be charged within the first preset time period (e.g., 1 second), the authentication information of the charging device can be resent to the vehicle to be charged until the preset first retransmission limit condition (e.g., 3 times) is reached. If the authentication information of the vehicle to be charged is still not received after that, it can be considered that the authentication of the vehicle to be charged, which has successfully connected wirelessly with the charging device, has failed, and the wireless connection between the charging device and the vehicle to be charged is disconnected.

[0117] It should be noted that, in the above embodiment, if no verification information from the vehicle to be charged is received within the first preset time period, the authentication information of the charging device is resent to the vehicle to be charged. This is to prevent the communication between the charging device and the vehicle to be charged from being lost, causing both the charging device and the vehicle to enter a silent phase simultaneously, thus preventing the wireless connection between the charging device and the vehicle to be charged from being disconnected. This silent phase can be understood as the charging device and the vehicle to be charged being in an inactive state, i.e., unable to perform effective charging.

[0118] The charging control method provided in the embodiments of the present invention sends authentication information to the vehicle to be charged, so that the vehicle to be charged can authenticate the charging device based on the authentication information of the charging device. If no authentication information of the vehicle to be charged is received from the vehicle to be charged within a first preset time period, the authentication information of the charging device is resent to the vehicle to be charged until a preset first retransmission restriction condition is met, or the authentication information of the vehicle to be charged is received. If the preset retransmission restriction condition is met within the first preset time period, but the corresponding authentication information of the vehicle to be charged is not received, the wireless connection with the vehicle to be charged is disconnected. Thus, this application can, based on the fact that the charging device has not received the authentication information of the vehicle to be charged within the first preset time period, resent the authentication information of the charging device to the vehicle to be charged, so as to avoid the loss of communication content between the charging device and the vehicle to be charged, which would cause both the charging device and the vehicle to be charged to enter a silent stage and be unable to disconnect the wireless connection between the charging device and the vehicle to be charged.

[0119] The charging control method provided in the above embodiments of this application will be explained and described in detail below with reference to the accompanying drawings. Figure 6 A flowchart illustrating a charging control method provided in this application embodiment. Figure 4 This method is applied to vehicles. For example... Figure 6 As shown, the charging control method includes the following steps:

[0120] S610 establishes a wireless connection with charging devices.

[0121] Specifically, the charging device scans for the wireless signals of nearby vehicles to be charged via wireless connection. When the vehicle to be charged approaches, it wirelessly connects with the charging device. The method of wireless connection between the charging device and the vehicle to be charged can be selected according to the actual situation. For example, the wireless connection method can be WIFI connection, Bluetooth connection, ZigBee connection, or NFC connection, etc.

[0122] S620: Based on a wireless connection, a second time parameter is sent to the charging device. The second time parameter is used to enable the charging device to determine the charging permission status of the vehicle to be charged based on the detected first and second time parameters.

[0123] Specifically, based on the wireless connection established in step S610, the vehicle to be charged sends a second time parameter it has detected to the charging device. This second time parameter allows the charging device to determine whether the target vehicle is the vehicle to be charged connected to the charging device based on the matching result of the first and second time parameters detected by the charging device. When the target vehicle is determined to be the vehicle to be charged connected to the charging device, the charging permission status of the target vehicle can be determined, that is, the charging permission status of the vehicle to be charged wirelessly connected to the charging device can be determined, so as to ensure effective charging of the vehicle to be charged and the charging device, thereby avoiding the safety hazard caused by the vehicle to be charged and the vehicle to be charged wirelessly connected to the charging device not being the same vehicle.

[0124] Embodiments of the present invention provide a charging control method. A wireless connection is established between a vehicle and a charging device. Based on this wireless connection, a second time parameter is sent to the charging device. This second time parameter enables the charging device to determine the charging permission status of the vehicle to be charged based on the detected first and second time parameters. Therefore, this application can send the second time parameter to the charging device based on the wireless connection between the vehicle to be charged and the charging device. This allows the charging device to determine whether the target vehicle is the vehicle to be charged connected to the charging device based on the matching result of the detected first and second time parameters. When the target vehicle is determined to be the vehicle to be charged connected to the charging device, the charging permission status of the target vehicle can be determined, i.e., the charging permission status of the vehicle wirelessly connected to the charging device can be determined. This ensures effective charging between the vehicle to be charged and the charging device, thereby avoiding the safety hazard caused by the vehicle to be charged and the vehicle wirelessly connected to the charging device being different vehicles.

[0125] As an optional implementation method, Figure 7 A flowchart illustrating a charging control method provided in this application embodiment. Figure 5 .like Figure 7 As shown above, the method may also include:

[0126] S710. If no response message corresponding to the second time parameter is received from the charging device within the second preset time period, the new second time parameter is retransmitted to the charging device based on the wireless connection until the preset first retransmission limit condition is met, or the corresponding response message is received.

[0127] The first preset duration can be selected according to the actual situation. For example, the first preset duration can be selected as 1 second.

[0128] Optionally, the vehicle to be charged sends a second time parameter to the charging device with which it has successfully established a wireless connection. However, if the vehicle does not receive a response message corresponding to the second time parameter from the charging device within a second preset time period (e.g., 1 second), it can resend a new second time parameter to the charging device based on the wireless connection until a preset first retransmission limit condition is reached, i.e., a preset second retransmission count, such as 127 times. Alternatively, the vehicle receives a corresponding response message from the charging device within the preset first retransmission limit condition (e.g., 127 times).

[0129] S720: If the first retransmission restriction condition is met, but no corresponding response message is received, the wireless connection with the charging device is disconnected.

[0130] Optionally, if no response message is received from the charging device within a second preset time period (e.g., 1 second), the second time parameters of the vehicle to be charged can be retransmitted to the charging device until a preset first retransmission limit condition (e.g., 127 times) is reached. If no response message is still received from the charging device after this limit is reached, the wireless connection between the vehicle to be charged and the charging device is considered to have failed, and the wireless connection between the charging device and the vehicle to be charged is disconnected. The second time parameters may include a second insertion duration and a second closing duration.

[0131] It should be noted that in the above embodiment, if no response message is received from the charging device within the second preset time period, the second time parameter of the device to be charged is resent to the charging device. This is to prevent the communication content between the charging device and the vehicle to be charged from being lost, which would cause the charging device and the vehicle to be charged to enter a silent phase at the same time, thus making it impossible to disconnect the wireless connection between the charging device and the vehicle to be charged.

[0132] The charging control method provided in the embodiments of the present invention, if no response message corresponding to the second time parameter is received from the charging device within a second preset time period, resends a new second insertion duration wirelessly to the charging device until a preset first retransmission limit condition is reached; or, if a corresponding response message is received, and the first retransmission limit condition is reached but no corresponding response message is received, then the wireless connection with the charging device is disconnected. Therefore, this application allows the vehicle to resend the second time parameter to the charging device if the vehicle to be charged does not receive a response message from the charging device within the second preset time period. This avoids the charging device being unable to obtain the second time parameter due to lost communication content between the charging device and the vehicle to be charged, thus preventing both the charging device and the vehicle to be charged from entering a silent phase and being unable to disconnect the wireless connection.

[0133] Based on the same inventive concept, this application also provides a charging control device for use in charging equipment.
