[0025] The receiving end structure includes at least: 2.1. The second resonance module: receives the resonance signal from the transmitter, obtains the energy of wireless transmission through resonance induction with the first resonance module. It is connected to the second AC-DC power supply module, receives wireless power and converts it into DC power.

[0026] 2.2. The second AC-DC power supply module: charges the vehicle battery and converts the AC signal received by the second resonance module into DC power to supply the Bluetooth module at the receiving end. This design enables the Bluetooth module to be powered independently of the vehicle battery, avoiding over-reliance on the vehicle battery.

[0027] 2.3. Bluetooth module: The Bluetooth module is connected to the second AC-DC power supply module and is responsible for wirelessly transmitting the battery status and power information of the receiving end to the real-time adjustment device of the wireless charging power so that it can adjust the charging power.

[0028] The real-time adjustment device of the wireless charging power includes at least: 3.1. Function of the power adjustment device: Real-time detection of power transmission between the transmitter and the receiver. After receiving the battery status data from the Bluetooth module, such as voltage, current and other information, the system dynamically adjusts the input power of the transmitter based on this information to ensure optimal charging efficiency and safety.

[0029] Specifically, when the transmitting end and the receiving end are coil-coupled, the real-time adjustment device of the wireless charging power detects the resonant coupling signal between the two ends, and then enters the power calculation and adjustment stage.

[0030] The real-time adjustment device of the wireless charging power collects data from the first AC-DC power supply module of the transmitting end to obtain the first DC input voltage and the first DC input current.

[0031] The real-time adjustment device of the wireless charging power collects data from the second AC-DC power supply module at the receiving end to obtain the second DC input voltage and the second DC input current.

[0032] 102. If the battery parameters sent by the Bluetooth module of the receiving end are received, generating a power adjustment parameter according to the battery parameters and the real-time input power; Specifically, after detecting coupling induction between the transmitting end and the receiving end, the real-time adjustment device of the wireless charging power sends a power supply request to the Bluetooth module of the receiving end to ensure the normal operation of the Bluetooth module and request to establish a communication connection with the Bluetooth module.

[0033] When the Bluetooth module is successfully connected, the transmitter sends a parameter acquisition request to the Bluetooth module of the receiver, and the receiver returns the current parameters of the battery (such as voltage, current, temperature, etc.).

[0034] The real-time adjustment of the wireless charging power of the device is based on the received battery parameters (such as battery type, current charging status, etc.) and the real-time input power of the transmitter to calculate the corresponding power adjustment parameters.

[0035] The wireless charging power of the device is adjusted in real time by matching the corresponding charging characteristic parameters, such as charging current, voltage limit, etc., from the preset database according to the battery type.

[0036] The real-time adjustment device of wireless charging power calculates the control parameters required to adjust the transmitting end power according to the current status information of the battery (such as remaining power, temperature, etc.) and charging characteristic parameters.

[0037] 103. Perform an input power adjustment operation according to the power adjustment parameter.

[0038] The real-time adjustment device of the wireless charging power controls the first AC-DC power supply module of the transmitting end to adjust the input power according to the calculated power adjustment parameter, so that the transmitting end provides the preferred target power to the receiving end.

[0039] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: by real-time monitoring and adjustment of wireless charging power, all potential risks caused by battery aging, overcharging, etc. are effectively prevented. At the same time, the Bluetooth module is used to receive battery parameters and dynamically adjust the input power of the transmitter, which not only shortens the charging time, but also significantly optimizes the charging efficiency. In addition, the AC-DC module is separated from the wireless charging transmitter, which reduces the size of the transmitter and facilitates flexible installation and layout at various charging stations.

[0040] In the development of wireless charging technology, traditional wireless charging systems often only focus on the transmission efficiency of electric energy, ignoring the specific status of the battery at the receiving end. As a result, in actual applications, problems such as low charging efficiency, battery overheating or overcharging may occur, which not only affects the service life of the device, but also may bring safety hazards. In order to solve these problems, the present invention proposes an optional embodiment.

[0041] Reference Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a specific embodiment of step 101 of the method for real-time adjustment of wireless charging power in an embodiment of the present invention. Step 101 also includes the following specific implementation methods: 201. Requesting a second AC-DC power supply module in the receiving end to power a Bluetooth module in the receiving end, and requesting a communication connection with the Bluetooth module; Specifically, the real-time adjustment device of the wireless charging power first requests the second AC-DC power supply module in the receiving end to power the Bluetooth module, so that the Bluetooth module has power to perform communication operations.

[0042] Then, the real-time adjustment device of the wireless charging power establishes a communication connection with the Bluetooth module in the receiving end.

[0043] 202. If the Bluetooth module is successfully connected, send a parameter acquisition request to the Bluetooth module at the receiving end, wherein the Bluetooth module returns the battery parameters in response to the parameter acquisition request.

[0044] If the communication connection with the Bluetooth module is successfully established, the real-time adjustment device of the wireless charging power sends a parameter acquisition request to the Bluetooth module.

[0045] After receiving the request, the Bluetooth module obtains the current battery parameters (such as battery voltage, remaining power, battery temperature, etc.) from the battery management system at the receiving end according to the content of the request, and returns them to the real-time adjustment device of the wireless charging power.

[0046] In this optional embodiment, by acquiring detailed parameters of the receiving end battery in real time, the output power of the transmitting end can be adjusted more accurately to match the actual needs of the receiving end battery, thereby improving the charging efficiency. Knowing the specific status of the battery (such as temperature, voltage, etc.) helps prevent potential safety risks such as overcharging and overheating, and protects the safety of the battery and the device.

[0047] In the development of wireless charging technology, precise control of charging power has always been a technical difficulty. Traditional wireless charging systems often use a fixed charging power for charging, and cannot be dynamically adjusted according to the actual state of the battery and the charging environment. This leads to low charging efficiency and potential safety hazards. Furthermore, since the power conversion efficiency during wireless charging is affected by many factors (such as coil coupling degree, battery internal resistance, ambient temperature, etc.), traditional wireless charging does not specifically consider this problem. In order to solve these problems, the present invention proposes an optional embodiment.

[0048] Reference Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a specific embodiment of step 101 of the method for real-time adjustment of wireless charging power in an embodiment of the present invention. Step 101 also includes the following specific implementation methods: 1011. Perform a data acquisition operation on the first AC-DC power supply module in the transmitting end to obtain a first DC input voltage and a first DC input current, and perform a data acquisition operation on the second AC-DC power supply module in the receiving end to obtain a second DC input voltage and a second DC input current; Specifically, a small electric vehicle equipped with a wireless charging receiving device is placed close to a wireless charging transmitting device, and the wireless charging receiving coil is placed within the induction range of the transmitting device coil; The receiving device uses the coil coupling induction to reduce the voltage to 3.3V DC through the rectifier filter circuit and DC-DC circuit to power the receiving wireless communication module and the receiving control module, and establish a wireless link with the transmitting wireless communication module; 1012. Calculate the real-time input power of the transmitting end according to the first DC input voltage and the first DC input current, and calculate the real-time charging power of the receiving end according to the second DC input voltage and the second DC input current.

[0049] Get the DC input voltage and input current, and calculate the real-time input power P of the transmitter 发 , the input power P at the transmitter 发 The DC input voltage V DC and input current I DC The product of The battery voltage and battery input current of the receiving end are obtained through the wireless communication module, and the real-time charging power P of the receiving end is calculated. 接 , the charging power P at the receiving end 接 is the battery voltage V BAT and the battery input current I BAT The product of .

[0050] In this optional embodiment, by real-time acquisition and calculation of the power of the transmitter and receiver, the charging process can be controlled more accurately to ensure charging efficiency and safety. This method is not limited by the battery type and charging environment, and can be applied to a variety of wireless charging scenarios and different types of batteries. Real-time power data can also be used to diagnose potential faults of the wireless charging system, such as poor coil coupling, foreign object interference, etc., thereby improving the reliability and stability of the system.

[0051] In the development of wireless charging technology, traditional wireless charging systems often only focus on the transmission efficiency of electric energy, ignoring the specific status of the battery at the receiving end. As a result, in actual applications, problems such as low charging efficiency, battery overheating or overcharging may occur, posing safety hazards. In order to solve these problems, the present invention proposes an optional embodiment.

[0052] Step 102 also includes the following specific implementations: 1021. Matching battery charging characteristic parameters in a preset database according to the battery type in the battery parameters; Specifically, the receiving end battery type parameter is detected and matched with the corresponding battery charging characteristic parameter.

[0053] 1022. Determine a power control parameter according to the battery charging characteristic parameter.

[0054] Specifically, a power adjustment parameter is generated based on the battery charging characteristic parameter and a charging command is sent based on the power adjustment parameter to start constant current charging with the receiving end charging current set for this battery type. For example: when the battery is charged to the set voltage VCV, the receiving end step-down charging current is charged; when the battery is charged to the full-charge voltage, the receiving end trickle charging current is charged; and the trickle charging current is charged to the full-charge voltage of the battery and then stops charging; the receiving end charging current I is set. 限 is the limit value and the real-time receiving end charging current I BAT Use P for input I The algorithm calculates the control information S of the transmitter control module; the operating frequency of the high-frequency full-bridge inverter circuit is controlled by the control information S so that the charging current of the receiving end reaches the set charging current I 限 ; The control quantity information S is the duty cycle information of the high-frequency full-bridge inverter circuit.

[0055] Optionally, when the real-time charging power is less than the preset charging power, it is determined that a foreign object is present between the transmitting end and the receiving end, and the charging operation on the transmitting end is terminated. 正常 =P 接 / P 发 When the transmitter control module calculates that the charging efficiency is lower than 65%, it determines that there is a foreign object in the charging process and stops charging in time.

[0056] Optionally, when the difference between the real-time charging power and the real-time charging power is greater than or equal to a preset difference, the charging operation on the sending end is terminated.

[0057] It is easy to understand that the method of this embodiment can be applied not only to small electric vehicles, but also to small devices such as robotic devices and drone devices for wireless charging.

[0058] In this optional embodiment, by adjusting the charging power according to the actual type and characteristics of the battery, it is possible to ensure that the battery is charged under optimal conditions, thereby improving the charging efficiency. Overcharging or over-discharging will damage the battery life. By controlling the charging power, this can be avoided.

[0059] In the development of wireless charging technology, different battery types and states have different requirements for charging power. Traditional wireless charging systems often adopt fixed charging strategies and cannot be flexibly adjusted according to the real-time status of the battery, resulting in low charging efficiency and shortened battery life. In order to solve these problems, the present invention proposes an optional embodiment.

[0060] Step 1022 also includes the following specific implementations: 10221. Detect current battery status information of the receiving end; Specifically, the real-time adjustment device of the wireless charging power obtains the current battery status information by interacting with the receiving end, including but not limited to the remaining battery power, battery temperature, battery voltage, etc.

[0061] 10222. Calculate the power control parameter according to the charging characteristic parameter and the current battery status information.

[0062] Specifically, appropriate power control parameters are calculated in combination with current battery status information and matching battery charging characteristic parameters.

[0063] In this optional embodiment, by considering the current state and charging characteristics of the battery in real time, the charging power can be further accurately controlled on the basis of the original effect, thereby optimizing the charging efficiency.
