Description

Technical Field

[0001] The embodiments of the present application relate to the field of wireless charging technology, and in particular to a wireless charging abnormality alarm method, device, vehicle, and storage medium. Background Art

[0002] In the prior art, communication between a wireless charging module and the device to be charged primarily relies on a preset handshake protocol, such as sending and receiving PING signals to confirm the presence and connection status of the device to be charged. Once the device to be charged establishes a connection with the charging module and enters the power transmission state, the wireless charging module will continue to output power until it receives a disconnect signal from the device to be charged. However, in some cases, the device to be charged may suddenly stop charging due to software errors, hardware failures, or battery saturation, but does not send a disconnect signal according to the preset protocol. As a result, the wireless charging module cannot indicate a disconnection when the device is not charging, and the user does not receive a reminder when the device is not actually charging, thereby reducing the user experience.

[0041] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0042] Existing wireless charging technologies lack safety and user feedback mechanisms under abnormal operating conditions. Specifically, in wireless charging scenarios, if a device suddenly stops charging but fails to send a power transfer termination packet to the wireless charging module in a timely manner, the module lacks an effective mechanism to identify and respond to the abnormal situation. This can cause the module to continue outputting power while in an ineffective charging state, increasing the risk of overheating. Furthermore, users may not be immediately notified when charging stops, leading to unnecessary waiting and inconvenience, which in turn reduces the user experience.

[0043] An embodiment of the present application provides a wireless charging abnormality alarm method, comprising: in response to a wireless charging module being in a standby state, sending an extended digital signal to a device to be charged and obtaining a response signal fed back by the device to be charged, wherein the response signal is generated based on the extended digital signal; based on the response signal, controlling the transmission of power between the wireless charging module and the device to be charged; in response to the presence of power transmission between the wireless charging module and the device to be charged, obtaining an output parameter of the wireless charging module and a charging parameter of the device to be charged; and controlling the wireless charging module to issue an abnormality alarm signal based on the output parameter and the charging parameter.

[0044] The above optional embodiments of the present application can achieve the following beneficial effects: by actively sending an extended digital signal to the device to be charged when the wireless charging module is in the standby state and obtaining a response signal fed back by the device to be charged, and then controlling the power transmission process between the wireless charging module and the device to be charged based on the information in the response signal, monitoring the output parameters of the wireless charging module and the charging parameters of the device to be charged in real time during the power transmission, and finally controlling the wireless charging module to issue an abnormal alarm signal based on the above parameters, thereby achieving the purpose of immediate response to abnormal wireless charging conditions, thereby achieving the technical effect of improving the safety and user experience during the wireless charging process, and thus solving the technical problems of low safety and poor user experience of the wireless charging abnormality alarm method provided in the related art.

[0045] Example 1

[0046] This application embodiment provides a wireless charging abnormality alarm method, please refer to Figure 1 , including the following steps:

[0047] Step S11: in response to the wireless charging module being in a standby state, sending an extended digital signal to the device to be charged and obtaining a response signal fed back by the device to be charged, wherein the response signal is generated based on the extended digital signal;

[0048] Step S12: Based on the response signal, controlling the power transmission between the wireless charging module and the device to be charged;

[0049] Step S13: In response to the presence of power transmission between the wireless charging module and the device to be charged, obtaining output parameters of the wireless charging module and charging parameters of the device to be charged;

[0050] Step S14: Based on the output parameters and the charging parameters, the wireless charging module is controlled to send an abnormal alarm signal.

[0051] For example, the above-mentioned wireless charging abnormality alarm method can be applied to, but not limited to, the fields of vehicles, smart homes, commercial services, etc. It should be noted that the embodiments of the present disclosure use the vehicle field as an example to introduce the wireless charging abnormality alarm.

[0052] The standby state is used to indicate that the wireless charging module has been activated but has not yet established a charging connection with any device.

[0053] The above-mentioned device to be charged is a smart device that supports wireless charging function, including but not limited to smartphones, tablets, smart watches, wireless earphone charging boxes, etc. The above-mentioned device to be charged has a built-in wireless charging receiving coil, which can receive power from the wireless charging module without the need for physical connection, achieving convenient charging.

[0054] The extended digital signal is a specific high-frequency communication signal used to enable more refined communication between the wireless charging module and the device being charged. Specifically, the extended digital signal allows both parties to negotiate charging parameters such as maximum acceptable power, charging frequency, and battery status, thereby ensuring the safety and efficiency of the charging process.

[0055] For example, when a vehicle's wireless charging module is in standby mode—that is, it's activated but not connected to any device to be charged—it broadcasts an extended digital signal wirelessly to the surrounding area. Furthermore, upon receiving a response signal from the device to be charged, the wireless charging module adjusts its output power and frequency based on the detailed information provided in the response signal to ensure efficient and safe power transmission with the device to be charged. Once the adjustment is complete and the communication link is confirmed to be stable, the wireless charging module begins transmitting power to the device to be charged, and the device's wireless charging receiving coil begins receiving the power and converting it into the electricity required to charge the battery.

[0056] During the power transmission process, the wireless charging module continuously monitors output parameters, including actual output power and voltage, and simultaneously continuously obtains charging parameters of the device being charged, such as the current power received by the device and the battery charge status, through wireless communication. If, during the monitoring process, there is an abnormal discrepancy between the output parameters of the wireless charging module and the charging parameters of the device being charged—for example, the output power of the wireless charging module is significantly higher than the received power of the device being charged, or the voltage of the wireless charging module is outside the normal range—the wireless charging module will send an abnormal alarm signal to the infotainment domain controller (IDC) via the vehicle's communication network, triggering the vehicle system's alarm mechanism to alert the driver that a problem has occurred during the wireless charging process and that prompt attention and appropriate measures are needed, such as stopping charging to avoid safety risks or checking the position and connection status between the device being charged and the wireless charging module to ensure a smooth charging process and device safety.

[0057] Based on the above steps S11 to S14, when the vehicle's wireless charging module is in standby state, an extended digital signal is actively sent to the device to be charged and a response signal is fed back by the device to be charged. Then, based on the information in the response signal, the power transmission process between the wireless charging module and the device to be charged is controlled. During the power transmission, the output parameters of the wireless charging module and the charging parameters of the device to be charged are monitored in real time. Finally, based on the above parameters, the wireless charging module is controlled to issue an abnormal alarm signal, thereby achieving the purpose of immediate response to abnormal wireless charging conditions, thereby achieving the technical effect of improving the safety and user experience during the wireless charging process, and thus solving the technical problems of low safety and poor user experience of the wireless charging abnormality alarm method provided in the related art.

[0058] Optionally, in step S11, in response to the wireless charging module being in a standby state, sending an extended digital signal to the device to be charged includes:

[0059] Step S111, in response to the wireless charging module being in a standby state, performing a state detection on the wireless charging module to obtain a state detection result;

[0060] Step S112 : in response to the status detection result indicating that there is a device to be charged that generates electromagnetic induction with the wireless charging module, sending an extended digital signal to the device to be charged.

[0061] For example, when a vehicle's wireless charging module enters standby mode, it immediately initiates a built-in self-test program to assess its own health and performance indicators, including but not limited to checking the integrity of the transmitting coil, verifying the conduction state of the metal oxide semiconductor field effect transistor bridge circuit (MOSFET bridge), verifying the version compatibility of the control system software, and ensuring the stability of the power supply to confirm whether the wireless charging module can safely transmit power. Furthermore, after the self-test program confirms that the wireless charging module meets the safe power transmission standards, if electromagnetic induction is detected, indicating that a device to be charged that matches the wireless charging module has entered the sensing range, the wireless charging module immediately responds by constructing and sending an extended digital signal to the device to be charged.

[0062] Based on the above steps S111 to S112, by performing an internal status test on the wireless charging module when entering the standby state, and after the test results show that the wireless charging module is healthy and meets the performance standards, capturing the device to be charged that generates electromagnetic induction with the wireless charging module and instantly sending an extended digital signal to the device, it can be ensured that each charging attempt is initiated when the wireless charging module is in the optimal state, and at the same time, quickly identify and prepare to establish a high-quality charging communication connection with the device to be charged, thereby eliminating charging failures or safety hazards caused by instability of the wireless charging module itself or poor compatibility with the device to be charged, thereby improving the efficiency and reliability of the wireless charging process.

[0063] Optionally, in step S112, in response to the status detection result indicating that there is a device to be charged that generates electromagnetic induction with the wireless charging module, sending an extended digital signal to the device to be charged includes:

[0064] Step S1121: In response to the status detection result indicating that there is a device to be charged that generates electromagnetic induction with the wireless charging module, a communication signal is sent to the device to be charged, wherein the communication signal is used to determine the connection status between the wireless charging module and the device to be charged;

[0065] Step S1122: In response to successfully sending the communication signal, obtaining a communication data packet from the device to be charged, wherein the communication data packet includes at least: a maximum receiving power of the device to be charged and an actual receiving power of the device to be charged;

[0066] Step S1123: Send an extended digital signal to the device to be charged based on the communication data packet.

[0067] The above-mentioned communication signal is an initial communication detection signal. In a wireless charging scenario, it is usually manifested as a PING signal or a similar handshake signal, which is used to detect the initial connection status between the wireless charging module and the device to be charged and confirm whether a valid communication link has been established between the two.

[0068] The above communication data packet is a power requirement and status data packet, including but not limited to the maximum received power of the device to be charged, the current actual received power and other status information, such as the battery type, charging requirements, health status, etc. of the device to be charged.

[0069] For example, assuming that the device to be charged is a smartphone that supports wireless charging, when the sensor built into the wireless charging module detects that the smartphone that generates electromagnetic induction with it enters its charging area, the wireless charging module immediately starts the initial communication detection and sends a PING handshake signal to the smartphone to confirm whether the two parties have established a valid wireless communication connection. After a successful handshake, assuming that during the current wireless charging process, the maximum received power recorded in the communication data packet fed back by the device to be charged is 15W, and the actual received power at the beginning of the handshake is 10W. Furthermore, based on the above communication data packet, the wireless charging module sends an extended digital signal to the smartphone through algorithm analysis, adjusts the charging power to the optimal state, ensures that it is neither overcharged nor undercharged, and maintains a stable charging efficiency, avoiding device damage or low charging efficiency problems that may be caused by power mismatch.

[0070] Based on steps S1121 to S1123 above, after detecting electromagnetic induction between the device to be charged and the wireless charging module and confirming the effective establishment of the communication link through a PING handshake signal, the wireless charging module can receive a communication data packet from the device to be charged, including the device's maximum received power and actual received power. Based on this communication data packet, the wireless charging module can not only determine whether the current charging status is normal, but also intelligently adjust the charging power by sending an extended digital signal to accurately match the actual needs of the device to be charged, avoiding power overload or underload, ensuring charging efficiency, and protecting the device safety.

[0071] Optionally, in step S1123, sending an extended digital signal to the device to be charged based on the communication data packet includes:

[0072] Step S21, performing format verification on the communication data packet to obtain a verification result;

[0073] Step S22 : In response to the verification result indicating that the communication data packet conforms to a preset format, an extended digital signal is sent to the device to be charged.

[0074] The above-mentioned preset format is a standardized communication protocol format. In the field of wireless charging technology, the wireless charging standard (Qi standard) developed by the Wireless Power Alliance or the Power Matters Alliance (PMA) standard, or other defined industry standards are generally followed. Specifically, the preset format includes but is not limited to specific fields and data types for transmitting status information including the maximum received power of the device to be charged, the current actual received power, the device type, the charging requirements, the battery health status, etc. Its purpose is to ensure that the wireless charging module can correctly identify and parse the data received from the device to be charged, so as to perform accurate power adjustment and status monitoring.

[0075] For example, when the wireless charging module detects a Qi-supported smartphone within its charging range, it immediately sends an initial PING handshake signal to establish a wireless communication link with the smartphone. Once the handshake is successful, the wireless charging module begins receiving communication data packets from the smartphone and performs format verification on the received communication data packets to ensure that they conform to the pre-set format of the Qi standard, including the correct fields, data types, and encoding methods. If the verification result indicates that the communication data packet format is correct, the wireless charging module will send an extended digital signal to the smartphone based on the power requirement information in the communication data packet, instructing it to adjust the charging power to achieve optimal charging efficiency.

[0076] Based on the above steps S21 to S22, by verifying the format of the communication data packet and sending an extended digital signal to the device to be charged based on the verification result, the stability and charging efficiency of the wireless charging system can be improved, ensuring that the wireless charging module can accurately understand the needs and status of the device to be charged, and then intelligently adjust the charging parameters to achieve both safe and efficient charging.

[0077] Optionally, in step S12: based on the response signal, controlling the power transmission between the wireless charging module and the device to be charged includes:

[0078] Step S121: determining the pairing status between the wireless charging module and the device to be charged based on the response signal, wherein the response signal includes a communication pairing protocol and a power requirement difference error control packet sent by the device to be charged;

[0079] Step S122: controlling power transmission between the wireless charging module and the device to be charged based on the pairing status.

[0080] For example, in the Qi standard, the communication pairing protocol requires the device to be charged to send an initialization packet containing its device ID and version information. After receiving the initialization packet, the wireless charging module will perform preliminary identity authentication and respond with a list of supported charging parameters. Subsequently, the two parties will negotiate the power and frequency through a series of interactive packets to determine the final charging settings. If at any stage it is found that the device to be charged does not meet the standards or poses a safety risk, the wireless charging module will not continue the pairing process, but will terminate the connection to prevent unauthorized devices from charging, thereby ensuring the safety of the entire charging process and the compatibility of the devices.

[0081] For example, when a smart car's wireless charging module detects a device to be charged, such as a Qi-compliant device, within its effective charging range, it immediately sends an initial PING handshake signal to attempt to establish a wireless communication connection with the device. Upon successful handshake, it then sends an extended digital signal to the device. Furthermore, upon receiving the extended digital signal, the device to be charged sends a response signal to the wireless charging module containing a communication pairing protocol and a power requirement discrepancy error control packet. The communication pairing protocol details the device ID, version information, supported charging power range, and security authentication data of the device to be charged. Upon receiving this information, the wireless charging module verifies the format and content to determine whether the device to be charged is legitimate and can be charged safely. The power requirement discrepancy error control packet also provides the device's current charging status, including battery level, required charging power, and any abnormalities during power transmission. Based on this information, the wireless charging module can determine the pairing status with the device to be charged and whether the conditions for initiating charging are met.

[0082] Based on steps S121 to S122 above, upon receiving a response signal from the device to be charged, including a communication pairing protocol and a power requirement difference error control packet, the wireless charging module can not only confirm the identity and charging compatibility of the device to be charged, but also adjust the output power based on the device's real-time charging needs, avoiding overcharging or undercharging while also reducing heat generation and efficiency issues caused by power mismatch. The aforementioned intelligent pairing and dynamic power management mechanisms enable the wireless charging module to provide optimal charging services for user devices in any charging environment, thereby improving safety and user experience during wireless charging.

[0083] Optionally, in step S1221, controlling power transmission between the wireless charging module and the device to be charged based on the pairing status includes:

[0084] Step S31, in response to the pairing status being pairing successful, controlling the wireless charging module to transmit power to the device to be charged;

[0085] Step S32: In response to the pairing status being pairing failure, resending the extended digital signal to the device to be charged and obtaining a response signal, wherein the pairing failure at least includes: no power transmission protocol exists between the wireless charging module and the device to be charged, the communication data packet sent by the device to be charged is an abnormal communication data packet, there is a communication error between the wireless charging module and the device to be charged, and the communication between the wireless charging module and the device to be charged times out.

[0086] The above-mentioned power transmission protocols are the rules followed by communication between devices during the wireless charging process, including but not limited to proprietary protocols, Qi standards, PMA standards, etc.

[0087] The above-mentioned abnormal communication data packets are data packets that do not comply with the preset communication standards or format requirements, specifically including but not limited to data packets with abnormal serial numbers, data packets with undefined function codes, data packets exceeding the maximum length limit, data packets missing necessary fields, data packets with abnormal timestamps, and erroneous status report data packets.

[0088] For example, in the Qi communication protocol, each data packet should be accompanied by a serial number to ensure the order and uniqueness of the message. If the serial number is repeated or jumps, it may indicate that the data packet is lost or retransmitted, resulting in communication confusion, and the current data packet can be determined as an abnormal communication data packet.

[0089] For example, the function code in the data packet is used to indicate the operation or command to be executed. If the received data contains a function code that the wireless charging module does not understand or is undefined, it will be regarded as an abnormal communication data packet;

[0090] For example, there is a strict maximum length limit for communication data packets between the wireless charging module and the device to be charged. An overlong data packet may be regarded as an abnormal communication data packet because it cannot be parsed.

[0091] For example, according to the Qi standard, each data packet must contain a set of basic fields, such as source address, destination address, length byte, data, and cyclic redundancy check value (CRC). If any of the required fields is missing, the data packet is considered an abnormal communication data packet.

[0092] For example, the timestamp in the data packet is used for synchronous communication. If the time displayed by the timestamp differs greatly from the current time of the wireless charging module, it may indicate that the data packet is severely delayed or there is a time synchronization problem, and the data packet is an abnormal communication data packet;

[0093] For example, the device to be charged periodically reports its status to the wireless charging module, including battery level, temperature, and power requirements. If the status report contains unreasonable or extreme parameter values, such as a negative battery level, it may cause a wireless charging control logic error, and the current data packet may be determined to be an abnormal communication data packet.

[0094] For example, when pairing is successful, the wireless charging module immediately controls the power transmission and starts wireless charging to the device to be charged, while monitoring the power transmission status in real time to ensure that the charging process is both safe and efficient. On the contrary, when pairing fails, the wireless charging module will resend the extended digital signal to the device to be charged, try to establish communication with the device to be charged again, and seek an opportunity to reacquire the response signal. If a valid response signal cannot be obtained after re-communication, or the communication data packet sent by the device to be charged still belongs to the above-mentioned abnormal communication data packet, the wireless charging module will continue to monitor and try different communication strategies until the conditions for successful pairing are met. At the same time, the wireless charging module will send a notification to the user, indicating the current pairing failure status and possible reasons, to help the user check the device to be charged or environmental problems, so as to solve the charging obstacles in time and ensure a safe and efficient charging experience.

[0095] Based on steps S31 to S32 above, when pairing is detected, the wireless charging module immediately initiates power transmission while monitoring the power transmission status to ensure charging safety and efficiency. If pairing fails, the wireless charging module automatically analyzes and eliminates communication obstacles, such as correcting data packet anomalies and trying multiple power transmission protocols until a stable connection is established. This not only avoids ineffective charging, but also improves the user's charging experience and ensures device safety and functional integrity during the wireless charging process.

[0096] Optionally, in step S13, in response to the presence of power transmission between the wireless charging module and the device to be charged, obtaining the output parameter of the wireless charging module includes:

[0097] Step S131, obtaining the input voltage, input current and transmission power loss of the wireless charging module;

[0098] Step S132: determining output parameters based on the input voltage, input current, and transmission power loss, wherein the output parameters include output current and output power.

[0099] The above-mentioned transmission power loss includes but is not limited to the loss consumed in the MOSFET bridge circuit, the transmission coil and the capacitor.

[0100] For example, assuming that the input voltage of the wireless charging module is V in =12V, input current is I in =2A, then its input power is P in =V in ×I in =24W. Assume that the transmission power loss is P loss =6W, then the actual output power of the wireless charging module that can be used for wireless charging is P usable =P in -P loss =18W.

[0101] For example, it is assumed that the charging voltage V out =10V, the output current is

[0102] Based on the above steps S131 to S132, by obtaining the input voltage, input current and transmission power loss of the wireless charging module, and determining the output parameters based on the input voltage, input current and transmission power loss, problems can be identified in a timely manner under abnormal circumstances, such as voltage fluctuations, excessive power loss, etc., and corresponding measures can be taken quickly, such as adjusting power output, stopping charging, etc., thereby preventing potential failures and extending the life of the equipment.

[0103] Optionally, in step S14, based on the output parameter and the charging parameter, controlling the wireless charging module to issue an abnormality alarm signal includes:

[0104] Step S141: Compare the output parameters with the charging parameters to obtain a comparison result, wherein the charging parameters include charging current and charging power;

[0105] Step S142: Based on the comparison result, the wireless charging module is controlled to issue an abnormality alarm signal.

[0106] For example, the wireless charging module monitors its output parameters in real time during the charging process, while also collecting the charging current and power of the charging device. If, at a certain moment, the output parameters of the wireless charging module deviate significantly from the charging parameters of the device being charged, the module quickly activates the abnormality alarm mechanism based on this comparison result, generates an abnormality alarm signal, and transmits the abnormality alarm signal to the IDC and the Central Computational Unit (CCU) via the vehicle's internal CAN bus network. Upon receiving the abnormality alarm signal, the CCU instructs the IDC to display the abnormality warning message "Wireless charging abnormality, please check the device" and notifies the vehicle's energy management system to appropriately adjust the power supply strategy to address potential energy waste or safety risks. Simultaneously, upon receiving the abnormality alarm signal, the IDC immediately updates the information on the vehicle's display screen, displaying the abnormality warning message to the user, reminding them to check the connection status of the charging device and whether there is any foreign object interference. The wireless charging module also automatically stops power output at this moment to prevent device overheating or other safety issues caused by the abnormal operating condition.

[0107] Based on steps S141 to S142, real-time monitoring and intelligent comparison of output parameters and charging parameters enable instant identification of abnormal charging conditions. If the comparison result fails to meet preset conditions, an abnormality alarm is triggered, automatically interrupting power transmission and alerting the user to check their equipment or eliminate foreign objects. The vehicle's energy management system is also notified to adjust its strategy, preventing energy waste and safety risks. This improves the safety and user experience of wireless charging.

[0108] Optionally, in step S142, based on the comparison result, controlling the wireless charging module to issue an abnormality alarm signal includes:

[0109] Step S1421: Determine the abnormal alarm type based on the comparison result and the preset alarm threshold, wherein the abnormal alarm type includes at least a charging stop alarm type and a foreign object alarm type;

[0110] Step S1422: Based on the abnormal alarm type, control the wireless charging module to send an abnormal alarm signal, wherein the abnormal alarm signal corresponds to the abnormal alarm type one by one.

[0111] For example, assuming that the difference between the output power of the wireless charging module and the charging power of the device to be charged is between [-0.5V, 0.5V], the device to be charged may be in a full charge protection state or charging is stopped due to an abnormality, and the current abnormal alarm type can be determined to be a stop-charging alarm type; assuming that the difference between the output voltage of the wireless charging module and the charging power of the device to be charged is greater than the preset foreign object threshold, there may be foreign objects between the device to be charged and the wireless charging module, causing charging to stop, and the current abnormal alarm type can be determined to be a foreign object alarm type.

[0112] For example, assuming that the difference between the output current of the wireless charging module and the charging current of the device to be charged is less than 0.2, the device to be charged may be in a full charge protection state or charging has stopped due to an abnormality, and the current abnormal alarm type can also be determined to be a stop charging alarm type.

[0113] It should be noted that the above-mentioned power difference range and preset foreign object threshold are both preset alarm thresholds in the embodiment of the present application. Depending on different wireless charging modules and devices to be charged, the above-mentioned preset alarm thresholds can be selected according to actual conditions and are not limited here.

[0114] Based on steps S1421 to S1422 above, by accurately identifying the comparison results of the output parameters and charging parameters, and determining the type of anomaly based on the preset alarm threshold, the corresponding abnormality alarm mechanism can be immediately activated. Whether it is an abnormal charging stop or the detection of a foreign object, it can trigger the wireless charging module to send a specific abnormality alarm signal, ensuring that the vehicle and user receive accurate information in a timely manner, avoiding potential risks, and enhancing the safety of wireless charging and user trust.

[0115] Optionally, the abnormal alarm type further includes: an overvoltage alarm type and an undervoltage alarm type. The wireless charging abnormal alarm method in this application further includes:

[0116] Step S41, obtaining the real-time voltage of the wireless charging module;

[0117] Step S42: in response to the real-time voltage being greater than the first threshold, determining that the abnormal alarm type is an overvoltage alarm type;

[0118] Step S43 : in response to the real-time voltage being less than a second threshold, determining that the abnormal alarm type is an undervoltage alarm type, wherein the second threshold is less than the first threshold.

[0119] For example, assuming that the first threshold is [16V, 17V], and the current real-time voltage is 18V, which is greater than the first threshold, it can be determined that the current abnormal alarm type is an overvoltage alarm type; assuming that the second threshold is [8.5V, 9.5V], when the current real-time voltage is 6V, it can be determined that the current abnormal alarm type is an undervoltage alarm type.

[0120] Based on steps S41 to S43 above, by acquiring the real-time voltage of the wireless charging module and comparing it with the first and second thresholds, the type of voltage anomaly can be quickly determined. When the voltage exceeds the normal range, whether it is overvoltage or undervoltage, the alarm type is immediately determined and the corresponding safety mechanism is triggered, thereby effectively controlling charging risks and ensuring the safety and stability of the wireless charging process.

[0121] Figure 2FIG. 1 is a schematic diagram of a wireless charging abnormality alarm system provided by an embodiment of the present application. Figure 2 As shown, the system includes a wireless charging module, a device to be charged, a right-side zone controller, a central processing unit, and an infotainment domain controller. These components can communicate via CAN signals or Ethernet + CANFD. During wireless charging, the presence of a device to be charged is determined by detecting electromagnetic induction between the wireless charging module and the device.

[0122] Figure 3 Schematic diagram of a wireless charging abnormality alarm method provided by an embodiment of the present application, such as Figure 3 As shown, during the wireless charging process, the wireless charging system is first initialized and, when the wireless charging module is in standby mode, a communication signal is sent to the device to be charged. If a device to be charged responds to the communication signal, an extended digital signal is sent to the device to be charged. Conversely, if no device to be charged responds to the communication signal, the current communication signal is terminated, power transmission ends, and the communication signal is sent to the device to be charged again.

[0123] Furthermore, based on the extended digital signal and the response signal generated by the device to be charged based on the extended digital signal, it is determined whether the wireless charging module and the device to be charged are successfully paired. If the wireless charging module and the device to be charged are successfully paired, the wireless charging module is controlled to transmit power to the device to be charged. Conversely, if the response signal generated by the device to be charged based on the extended digital signal indicates the absence of a power transmission protocol, an abnormal communication data packet, a communication error, or a communication timeout, the communication signal is resent to the device to be charged.

[0124] During the power transmission process, the output parameters of the wireless charging module and the charging parameters of the device to be charged are continuously obtained, and the above parameters are compared with preset thresholds based on the abnormality identification system to determine the abnormality alarm type. Specifically, when the real-time voltage of the wireless charging module is greater than a first threshold, it is in an overvoltage protection state and charging should be stopped. The corresponding abnormality alarm type is an overvoltage alarm type. When the real-time voltage of the wireless charging module is less than a second threshold, it is in an undervoltage protection state and charging should be stopped. The corresponding abnormality alarm type is an undervoltage alarm type. When the difference between the output power of the wireless charging module and the charging power of the device to be charged is within a preset alarm threshold range, or the difference between the output current of the wireless charging module and the charging current of the device to be charged is less than a preset alarm threshold, it is in a full charge protection state or an abnormal charging stop state. The corresponding abnormality alarm type is a charging stop alarm type. When the difference between the output power of the wireless charging module and the charging power of the device to be charged is less than a preset alarm threshold, it indicates that a foreign object is present between the wireless charging module and the device to be charged and charging should be stopped. The corresponding abnormality alarm type is a foreign object alarm type.

[0125] It should be noted that Figure 3 The preset alarm threshold in can be flexibly selected according to actual conditions and is not limited to using the same value. At the same time, the first threshold is greater than the second threshold.
