[0039] Receiver: The receiver is a device that receives wireless power from the transmitter and converts it into electrical power that can be used to charge the battery. In the two-wheeled vehicle charging scenario, the receiver is usually a wireless charging receiver installed on the two-wheeled vehicle.

[0040] Communication address: In the control method of the wireless charging device, the communication address is used to uniquely identify the accessed transmitter for data transmission and control.

[0041] Battery real-time data: refers to the real-time status information of the receiving end battery during the charging process, including but not limited to voltage, current, temperature, internal resistance, capacity decay, number of cycles, charging efficiency and discharging efficiency, etc. It is crucial for the subsequent dynamic adjustment of charging parameters.

[0042] Control parameters of charging operation: refers to various parameters that control the charging process, such as charging current, charging voltage, charging time, charging mode (such as constant current charging, constant voltage charging, pulse charging, etc.) and coil frequency, etc. Adjustments are made based on real-time battery data to optimize charging efficiency and safety.

[0043] Coil spacing: In a wireless charging system, the transmitter and receiver usually transfer energy through the principle of electromagnetic induction. The coil spacing refers to the relative distance between the electromagnetic coils of the transmitter and receiver, which affects the efficiency and stability of wireless charging.

[0044] Optimal resonant frequency: When the coils at the transmitting and receiving ends operate at the same resonant frequency, the energy transfer efficiency is the highest. The optimal resonant frequency refers to the frequency at which the system can achieve the maximum energy transfer efficiency.

[0050] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a control method of a wireless charging device in an embodiment of the present invention includes:

[0051] 101. When detecting that a sender has accessed, assigning a communication address to the sender;

[0052] Specifically, the control device of the wireless charging device continuously monitors the signal changes in the wireless charging area to detect whether a new transmitter (such as a wireless charging pad or a wireless charging stand) is connected. When a new transmitter is detected, the control device shakes hands with the transmitter through a preset communication protocol (such as Bluetooth, Wi-Fi Direct, NFC, etc.) to confirm its identity and type.

[0053] After confirming the identity of the sender, the control device allocates a unique communication address to the sender from its internal address pool, and associates the address with the identity information of the sender and stores it in the memory of the control device.

[0054] The control device sends the assigned communication address to the sender and waits for a confirmation reply from the sender to ensure that the address allocation is successful.

[0055] 102. Perform a charging operation for the receiving end according to the mutual inductance value, and collect receiving end data returned by the Bluetooth module in the receiving end;

[0056] Specifically, the control device of the wireless charging device monitors the communication from each sending end, and when receiving the receiving end access information reported by a certain sending end, identifies the sending end according to the previously allocated communication address.

[0057] After confirming that the receiving end is connected, the control device sends a charging start instruction to the sending end through the communication address, and controls the sending end to start performing a charging operation for the receiving end.

[0058] At the same time, the control device sends a data request instruction to the transmitter, requiring the transmitter to obtain the real-time battery data (such as voltage, current, temperature, etc.) of the receiver through its wireless charging interface or an additional communication module (such as Bluetooth low energy BLE).

[0059] After the transmitter obtains the real-time data of the battery according to the instruction, it transmits the data back to the control device through the previously assigned communication address.

[0060] 103. Adjust charging parameters of the charging operation according to the receiving end data.

[0061] Specifically, after the control device of the wireless charging device receives the real-time battery data, it first confirms the sender and receiver of the data source according to the communication address, and then parses and analyzes the data to evaluate the battery status (such as power, health, temperature, etc.).

[0062] Based on the real-time battery data and preset charging strategies (such as fast charging, slow charging, constant temperature charging, etc.), the control device calculates and determines the optimal charging control parameters (such as charging current, charging voltage, charging time, etc.).

[0063] The control device of the wireless charging device sends the adjusted charging control parameters to the corresponding sending end through the communication address, and the sending end adjusts the charging operation according to the new parameters to achieve precise control of the battery at the receiving end.

[0064] During the entire charging process, the control device continuously monitors the real-time data of the battery and dynamically adjusts the charging parameters as needed to ensure the safety, efficiency and battery health of the charging process.

[0065] In an embodiment of the present invention, when the transmitter is detected to be connected, a communication address is assigned to the transmitter; when the transmitter reports that the receiver is connected, the transmitter is controlled to perform a charging operation for the receiver according to the communication address, and the transmitter is controlled to obtain and transmit back the real-time battery data of the receiver according to the communication address; when the real-time battery data is received, the control parameters of the charging operation are adjusted according to the communication address and the real-time battery data. By assigning a communication address to the transmitter, effective communication with the receiver is achieved, solving the problem of insufficient communication of traditional wireless charging devices. Charging efficiency is improved by acquiring battery data in real time and dynamically adjusting charging parameters. At the same time, it supports the control and management of multiple devices charging at the same time, which is convenient for remote management and maintenance.

[0066] With the popularization and expansion of wireless charging technology, how to effectively manage and maintain the batteries of wireless charging devices has become an urgent problem to be solved. Traditional battery management methods can only provide basic power display and charging status prompts, and cannot fully reflect the health of the battery. In order to solve the above technical problems, the present invention proposes an optional embodiment.

[0067] Specifically, refer to Figure 2 , Figure 2 This is a schematic diagram of a specific embodiment after step 102 of the control method of the wireless charging device in the embodiment of the present invention. After step 102, the following specific implementation methods are also included:

[0068] 201. When receiving the real-time battery data, calculate the battery health index corresponding to the receiving end according to the voltage, current, temperature, internal resistance, capacity attenuation, number of cycles, charging efficiency and discharging efficiency in the real-time battery data;

[0069] Specifically, when the sending end successfully obtains and transmits back the real-time battery data of the receiving end, the data is received. The received real-time battery data is processed, and the health index of the receiving end battery is calculated by a preset algorithm, taking into account multiple factors such as voltage, current, temperature, internal resistance, and long-term performance parameters such as battery cycle times and capacity attenuation. Among them:

[0070] Voltage: The voltage of a battery is a physical quantity that measures the uniformity of charge distribution inside the battery, and represents the potential difference between the positive and negative poles of the battery.

[0071] Current: The direction of current flows from the positive electrode to the negative electrode. During the discharge process, the chemical reaction inside the battery releases energy, driving electrons to flow from the positive electrode to the negative electrode, forming a current. The current intensity is the algebraic sum of the amount of charge passing through a certain cross section of the conductor per unit time, and is usually represented by the letter A.

[0072] Temperature: refers to the phenomenon of heating of the battery surface due to chemical and electrochemical changes in the internal structure, electron migration and material transfer during battery use. Changes in battery temperature will affect the performance and life of the battery. Excessively high temperature will accelerate the rate of chemical reactions inside the battery, leading to accelerated battery aging.

[0073] Internal resistance: refers to the resistance encountered by the current flowing through the battery when the battery is working. It includes two parts: ohmic internal resistance and polarization internal resistance. Ohmic internal resistance is mainly composed of electrode materials, electrolyte, diaphragm resistance and contact resistance of various parts, while polarization internal resistance is caused by electrochemical polarization and concentration polarization. The internal resistance of the battery is an important technical indicator to measure the battery performance. The battery with small internal resistance has strong large current discharge capacity, and vice versa.

[0074] Capacity decay: refers to the phenomenon that the amount of charge that a battery can store decreases over time and with increasing usage. This decay is caused by a variety of factors, including chemical reactions, temperature, vibration, etc. Battery capacity decay can lead to problems such as shortened device battery life, insufficient power, and long battery charging time, affecting user experience and work efficiency.

[0075] Cycle count: refers to the count after a battery completes a complete charge and discharge process. Each time a battery is fully charged and then fully discharged is called a battery cycle. As the number of battery cycles increases, the battery's performance will gradually decline, the capacity will decrease, the charging speed will slow down, etc.

[0076] Charging efficiency: refers to the ratio of the actual electric energy charged into the battery to the electric energy consumed during the charging process. It reflects the energy conversion efficiency of the battery during the charging process.

[0077] Discharge efficiency: refers to the ratio of the actual electric energy released by the battery during the discharge process to the electric energy initially stored in the battery. It reflects the energy utilization efficiency of the battery during the discharge process.

[0078] Optionally, substitute the above data into a preset formula to obtain the battery health index, which is as follows:

[0079]

[0080] Among them, SoH (%) is the battery health index (State of Health, SoH).

[0081] C nom is the rated capacity of the battery.

[0082] C actual It is the actual capacity of the current battery, which can be measured by full charge and full discharge method.

[0083] T is the average operating temperature of the battery.

[0084] I is the average operating current.

[0085] V is the average operating voltage of the battery.

[0086] R is the internal resistance of the battery, which may require specific instruments to measure.

[0087] Cyckes is the number of cycles of the battery.

[0088] charge It is the charging efficiency.

[0089] discharge is the discharge efficiency.

[0090] f(·) is a function that comprehensively considers the effects of temperature, current, voltage, internal resistance, number of cycles, and charging and discharging efficiency on the health status of the battery. The form and parameters of this function can be determined based on the test data and statistical analysis of the specific battery.

[0091] 202. Output the battery health index.

[0092] In this optional embodiment, the user can understand the battery health status of the device in real time and take corresponding measures in time, such as replacing the battery, optimizing charging habits, etc., so as to extend the service life of the device. By monitoring the battery health status, potential battery failures or safety hazards can be discovered in time to avoid device damage or safety accidents caused by battery problems. By optimizing charging operations and battery management, unnecessary power consumption and battery loss can be reduced.

[0093] With the popularization and expansion of wireless charging technology, how to effectively manage and maintain the battery resources of wireless charging devices has become an important issue. Traditional battery management methods often rely on user experience or regular maintenance inspections, which have problems such as low efficiency and insufficient accuracy. In order to solve the above technical problems, the present invention proposes an optional embodiment.

[0094] Optional, see Figure 3 , Figure 3 2 is a schematic diagram of a specific embodiment of step 202 of the control method of the wireless charging device in an embodiment of the present invention. Step 202 also includes the following specific implementation methods:

[0095] 2021. When the battery health index reaches a preset threshold, generate a warning instruction according to the battery health index;

[0096] 2022. Send the early warning instruction to the sending end according to the communication address, wherein when the sending end receives the early warning instruction, it responds to the early warning instruction and performs an early warning prompt operation.

[0097] Specifically, when the battery health index reaches a preset threshold, a warning instruction will be generated according to the battery health index. The warning instruction will be sent to the sender through the communication address of the wireless charging device. After receiving the warning instruction, the sender will perform corresponding warning prompt operations, such as sounding an alarm, lighting an indicator light, displaying a warning message on the display screen, etc., to remind the user to pay attention to the health of the battery.

[0098] In this optional embodiment, through the early warning prompt operation, the user can timely understand the health status of the battery and take corresponding measures to avoid device failure or performance degradation caused by battery problems.

[0099] With the popularization of wireless charging technology and the expansion of its application scope, the number and types of wireless charging devices are increasing. In order to ensure that these devices can operate stably and meet the growing needs of users, regular OTA upgrades become particularly important. However, traditional upgrade methods often require indiscriminate upgrade operations on all devices, which is not only inefficient but may also cause unnecessary waste of resources. In order to solve the above technical problems, the present invention proposes an optional embodiment.

[0100] Optional, see Figure 3 , Figure 3 This is a schematic diagram of a specific embodiment after step 101 of the control method of the wireless charging device in the embodiment of the present invention, and the following specific implementation methods are also included after step 101:

[0101] 203. Store the communication address in a communication address database, wherein the number of communication addresses in the communication address database corresponds to the number of connected sending terminals;

[0102] 204. When an OTA upgrade instruction is detected, dividing the target communication address and the non-target communication address in the communication address database;

[0103] 205. Send the OTA upgrade instruction to the target communication address, wherein the target sending end corresponding to the target communication address executes the OTA upgrade instruction when receiving the OTA upgrade instruction.

[0104] Specifically, when the wireless charging device detects that a transmitter has been connected, it allocates a unique communication address to the transmitter and stores the address in a communication address database. The number of records in the communication address database corresponds to the number of transmitters that have been connected.

[0105] When the wireless charging device detects an OTA (Over-the-Air) upgrade instruction, it will divide the target communication address and non-target communication address in the communication address database. The target communication address corresponds to the transmitter that needs to be upgraded by OTA, while the non-target communication address corresponds to the transmitter that does not need to be upgraded at present.

[0106] The wireless charging device sends the OTA upgrade command to the target communication address. The target transmitter that receives the upgrade command will perform the corresponding upgrade operation to upgrade its software version or fix known problems.

[0107] In this optional embodiment, by assigning communication addresses to the transmitters and storing them in a database, the control device of the wireless charging device can accurately identify which transmitters need to be OTA upgraded, thereby avoiding unnecessary upgrade operations on all transmitters and improving upgrade efficiency. Accurate upgrade control reduces unnecessary communication and data transmission, thereby reducing energy consumption and costs during the upgrade process.

[0108] During the OTA upgrade process, if the upgrade instruction is mistakenly sent to devices that do not need to be upgraded, these devices may become unstable or fail. In order to avoid this situation, the present invention proposes an optional embodiment to solve the above technical problem.

[0109] Optionally, step 205 also includes the following specific implementations:

[0110] 2051. Disable non-target communication addresses in the communication address database, and send the OTA upgrade instruction to the target communication address.

[0111] Specifically, before sending the OTA upgrade instruction, the wireless charging device will disable the non-target communication addresses in the communication address database to ensure that the upgrade instruction will only be sent to the target sending end that needs to be upgraded.

[0112] After disabling the non-target communication address, the control device of the wireless charging device sends the OTA upgrade instruction to the non-disabled target communication address. The target sending end that receives the upgrade instruction will perform the corresponding upgrade operation.

[0113] In this optional embodiment, by disabling non-target communication addresses, the wireless charging device can reduce interference with other devices during the upgrade process, ensuring the smooth progress of the upgrade process, and avoiding the upgrade instruction from being mistakenly sent to a device that does not need to be upgraded, thereby improving the security of the upgrade process.

[0114] Optionally, monitor the upgrade completion notification message returned from the target transmitting end in response to the OTA upgrade instruction; when the upgrade completion notification message is received, cancel the disabling of the non-target communication address. Specifically, when there are multiple target transmitting ends, when the upgrade completion notification messages from all target transmitting ends are received, cancel the disabling of the non-target communication address. Among them, by canceling the disabled state of the non-target communication address, the wireless charging device can ensure that all devices can work normally after the upgrade is completed. This mechanism enables the wireless charging device to flexibly control the status of different devices during the upgrade process, thereby improving the flexibility and reliability of the entire wireless charging system.
