These include ECG monitoring devices for monitoring electrocardiogram (ECG) signals, blood pressure monitoring devices for monitoring blood pressure, and wearable devices that centrally display multiple physiological signals. All these wearable electronic products suffer from battery consumption issues and require timely charging after a period of use. Therefore, configuring charging equipment to manage the charging of these electronic products with different charging capacities and meet the need for timely charging has become an urgent problem to solve. Summary of the Invention

[0003] Therefore, it is necessary to provide a smart charging device and a combined charging device to address the aforementioned technical problems.

[0004] In a first aspect, this application provides a charging device for providing charging current to wearable electronic products with different charging powers; the charging device includes a base and a power interface, the base is provided with at least a first charging slot and a second charging slot, the first charging slot is used to place a first charging load, and the second charging slot is used to place a second charging load; the charging power of the first charging load is less than the charging power of the second charging load.

[0005] The charging device further includes a charging management circuit, which includes a first charging branch, a second charging branch, and a control circuit.

[0006] The first charging branch is used to electrically connect to the first charging load;

[0007] The second charging branch is used to electrically connect to the second charging load;

[0008] The control circuit is electrically connected to the power interface. The control circuit is used to monitor the operating status parameters of the first charging branch and the second charging branch respectively, and manage the first charging mode and / or the second charging mode according to the operating status parameters. In the first charging mode, the first charging branch is controlled to charge part or all of the first charging load, and the second charging branch is controlled to suspend charging the second charging load. In the second charging mode, the first charging branch is controlled to charge all of the first charging load, and the second charging branch is controlled to charge part or all of the second charging load.

[0009] In some embodiments, the operating status parameters include operating temperature parameters, and the control circuit further includes a temperature monitoring chip, which is used to simultaneously monitor the operating temperature parameters of the first charging branch and the second charging branch.

[0010] When the operating temperature parameter is higher than the temperature alarm threshold, the control circuit shuts down the first charging mode and the second charging mode, and stops charging the first charging load and the second charging load.

[0011] Alternatively, if the operating temperature parameter is higher than the first safety threshold but lower than the temperature alarm threshold, the control circuit activates the first charging mode.

[0012] Alternatively, if the operating temperature parameter is lower than the first safety threshold, the control circuit activates the second charging mode.

[0013] In some embodiments, the operating state parameters further include branch current parameters; when the first charging mode is activated, the control circuit is also used to monitor the first current parameter of the first charging branch, and when the first current parameter is higher than the first current threshold, the control circuit controls the first charging branch to charge a portion of the first charging load.

[0014] In some embodiments, the operating state parameters further include a load voltage value; when the first charging mode is activated, the control circuit is also configured to monitor the load voltage value of the first charging load electrically connected to the first charging branch, and when the load voltage value is greater than the branch voltage value, control the first charging branch to charge a portion of the first charging load according to the load voltage value.

[0015] In some embodiments, the operating state parameters further include branch current parameters; when the second charging mode is activated, the control circuit is also used to monitor the second current parameter of the second charging branch, and when the second current parameter is higher than the second current threshold, the control circuit controls the second charging branch to charge a portion of the second charging load.

[0016] In some embodiments, when the first charging mode is activated, the control circuit is further configured to monitor the power value of the first charging load. If the power value is not lower than the power threshold, the control circuit controls the first charging branch to stop charging the first charging load and switches the first charging mode to the second charging mode.

[0017] In some embodiments, the charging management circuit further includes a charging trunk line, which is connected to the first charging branch line and the second charging branch line; when the second charging mode is activated, the control circuit is also used to monitor a third current parameter of the charging trunk line, and when the third current parameter exceeds a third current threshold, the control circuit switches the second charging mode to the first charging mode.

[0018] In some embodiments, the base has a first inclined portion and a second inclined portion, the first charging slot is disposed on the first inclined portion, and the second charging slot is disposed on the second inclined portion.

[0019] In some embodiments, the base is provided with an in-situ detection unit, which is used to detect whether the first charging load is placed in the first charging slot and whether the second charging load is placed in the second charging slot.

[0020] Secondly, this application also provides a combined charging device, including multiple charging devices as described in the first aspect above, wherein the multiple charging devices are combined and installed as one unit.

[0021] The aforementioned charging devices and combined charging devices divide wearable electronic products into a first charging load and a second charging load based on their charging power. A first charging mode and a second charging mode are set according to the first and second charging loads, where the charging power of the first charging load is less than that of the second charging load. Considering that the first charging load has a higher charging priority and that disconnecting the first charging load yields less remaining charging resources than disconnecting the second charging load, a tiered charging control method is adopted. In both the first and second charging modes, the charging needs of the first charging load are prioritized to varying degrees. This ensures that if the charging device needs to shut down due to full load operation or potential overheating, only a portion of the charging circuits need to be closed. This allows for the normal use of some wearable electronic products while eliminating potential faults and achieving intelligent charging. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] Unless otherwise defined, the technical or scientific terms used in this application shall have the general meaning as understood by one of ordinary skill in the art to which this application pertains. Words such as “a,” “an,” “an,” “the,” “the,” and “these,” used in this application, do not indicate quantitative limitation and may be singular or plural. The terms “comprising,” “including,” “having,” and any variations thereof used in this application are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or modules (units) is not limited to the listed steps or modules (units) but may include steps or modules (units) not listed, or may include other steps or modules (units) inherent to such processes, methods, products, or devices. The terms “connected,” “linked,” and “coupled,” used in this application, are not limited to physical or mechanical connections but may include electrical connections, whether direct or indirect. The term “multiple” used in this application refers to two or more. The "and / or" operator describes the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: A alone, A and B simultaneously, and B alone. Typically, the character " / " indicates that the objects before and after it are in an "or" relationship. The terms "first," "second," and "third," etc., used in this application are merely for distinguishing similar objects and do not represent a specific ordering of the objects.

[0034] Traditional charging devices generate heat when charging wearable electronic devices. When multiple devices are charging simultaneously, the charging temperature can become excessively high, potentially damaging the charging device or the devices themselves. The traditional solution relies on manual inspection and intervention, cutting off power when the temperature is detected. However, this method of automatically shutting off power at the first sign of high temperature cannot meet the normal operating requirements of some wearable devices and degrades the user experience.

[0035] To address the issue that traditional charging devices have relatively simple and unintelligent charging strategies, one embodiment provides a charging device that includes a base and a power interface. Figure 1 This is a structural diagram of the base. Figure 1 As shown, the base 1 has at least a first charging slot 11 and a second charging slot 12. The first charging slot 11 is used to place a first charging load, and the second charging slot 12 is used to place a second charging load. The charging power of the first charging load is less than the charging power of the second charging load. Wearable electronic products can be categorized according to charging current into heavy-load devices (1000mA), medium-load devices (600mA), and light-load devices (200mA), or further subdivided into multiple types; this embodiment does not impose such limitations. Wearable electronic products include, but are not limited to, HUBs (medical electronic watches), ECG (Electrocardiogram, electrocardiogram detection devices), and blood pressure monitoring devices. In this application, "wearable electronic product" and "electronic product" both refer to charging loads.

[0036] Optional, Figure 2 A schematic diagram of the base's appearance is provided. For example... Figure 2 As shown, the base 1 has a first inclined portion 13 and a second inclined portion 14. The first charging slot 11 is disposed on the first inclined portion 13, and the second charging slot 12 is disposed on the second inclined portion 14. Traditional charging devices enclose electronic products in a sealed environment within the main body, using a display screen or LEDs to indicate the charging status externally. However, the display is not very intuitive and suffers from false alarms and cumbersome querying. Therefore, this embodiment provides an inclined portion on the base 1, and places the charging slots on the inclined portion. By using an inclined design, the charging status of various electronic products in the charging device can be seen intuitively, and the charging status of a single electronic product can be captured most quickly. The inclined design also makes it convenient for users to pick up and remove electronic products.

[0037] Furthermore, Figure 3 A schematic diagram of another base structure is provided. (See diagram below.) Figure 3As shown, the base 1 is equipped with an presence detection unit 15, which is used to detect whether the first charging load is placed in the first charging slot 11 and whether the second charging load is placed in the second charging slot 12. The presence detection unit 15 can detect whether the electronic product is correctly connected to the corresponding charging branch. When the presence detection unit 15 detects the presence signal, it will trigger the charging device to turn on the output voltage of the corresponding charging branch. Optionally, the presence detection unit 15 can be a light sensor (detecting light intensity) or a pressure sensor (e.g., a mechanical button), and correspondingly, the presence signal can be a light sensor signal or a pressure sensor signal. This embodiment determines whether an electronic product is connected to the charging branch by detecting the presence signal, and then decides whether to turn on the output voltage of the corresponding charging branch, which can prevent accidental human contact and leakage.

[0038] Figure 4 This is a schematic diagram of the charging management circuit in this embodiment. Figure 4 As shown, the charging device also includes a charging management circuit 2, which includes a first charging branch 21, a second charging branch 22, and a control circuit 23. The first charging branch 21 is used to conductively connect to a first charging load; the second charging branch 22 is used to conductively connect to a second charging load; the control circuit 23 is conductively connected to a power interface, and the control circuit 23 is used to monitor the operating status parameters of the first charging branch 21 and the second charging branch 22 respectively, and manage the first charging mode and / or the second charging mode according to the operating status parameters. In the first charging mode, the first charging branch 21 is controlled to charge part or all of the first charging load, and the second charging branch 22 is controlled to pause charging the second charging load. In the second charging mode, the first charging branch 21 is controlled to charge all of the first charging load, and the second charging branch 22 is controlled to charge part or all of the second charging load.

[0039] In this embodiment, the control circuit 23 can be implemented using an MCU chip. Operating status parameters include operating temperature parameters. When the control circuit 23 detects that the operating temperature parameters of one or more charging branches are too high, it will shut down the corresponding charging branch to reduce heat generation. In some embodiments, if the operating temperature parameter is higher than the temperature alarm threshold, the control circuit 23 shuts down the first charging mode and the second charging mode, stopping charging the first charging load and the second charging load; or, if the operating temperature parameter is higher than the first safety threshold but lower than the temperature alarm threshold, the control circuit 23 starts the first charging mode; or, if the operating temperature parameter is lower than the first safety threshold, the control circuit 23 starts the second charging mode.

[0040] For example, if the control circuit 23 detects that the operating temperature parameter is higher than the temperature alarm threshold, the control circuit 23 shuts down the first charging mode and the second charging mode, stopping charging the first charging load and the second charging load. The charging device provided in this embodiment ensures safe charging during the charging process.

[0041] After charging the first and second charging loads stops, the temperature of the charging device will decrease over time. During this temperature drop, the control circuit 23 continues to monitor the operating temperature parameters. If the operating temperature parameter is detected to be higher than the first safety threshold but lower than the temperature alarm threshold, the control circuit 23 initiates the first charging mode. At this time, the charging device supports charging some of the charging loads. Some or all of the first charging loads can be connected to the charging device, and the first charging mode can be activated, i.e., controlling the first charging branch 21 to charge some or all of the first charging loads, and controlling the second charging branch 22 to suspend charging the second charging load.

[0042] When the control circuit 23 detects that the operating temperature parameter is lower than the first safety threshold, the control circuit 23 activates the second charging mode. At this time, the charging device supports supplying power to the first charging load and the second charging load, that is, controlling the first charging branch 21 to charge the entire first charging load, and simultaneously controlling the second charging branch 22 to charge part or all of the second charging load.

[0043] This embodiment divides the wearable electronic product into a first charging load and a second charging load based on its charging power. A first charging mode and a second charging mode are set according to the first and second charging loads, where the charging power of the first charging load is less than that of the second charging load. Considering that the first charging load has a higher charging priority, in this embodiment, the lower charging power is set to have a higher charging priority. Furthermore, disconnecting the first charging load yields less remaining charging resources than disconnecting the second charging load. Therefore, a tiered charging control method is adopted. In both the first and second charging modes, the charging needs of the first charging load are prioritized to varying degrees. This ensures that if the charging device needs to shut down due to full load operation or high temperature risks, only a portion of the charging branches need to be shut down. This eliminates potential faults and achieves intelligent charging while still allowing some wearable electronic products to function normally.

[0044] In one embodiment, Figure 5 A schematic diagram of another charging management circuit is provided. (For example...) Figure 5 As shown, the operating status parameters include the operating temperature parameters. The control circuit 23 also includes a temperature monitoring chip 24, which is used to simultaneously monitor the operating temperature parameters of the first charging branch 21 and the second charging branch 22.

[0045] In practical applications, the charging management circuit includes a circuit board, on which the first charging branch 21 and the second charging branch 22 are mounted. The operating temperature can be used as a parameter by monitoring the circuit board temperature, or the ambient temperature of the entire charging device can be used as a parameter. This embodiment does not impose any limitations on this.

[0046] In one embodiment, the operating status parameters include not only the operating temperature parameter but also the load voltage value. When the first charging mode is activated, the control circuit 23 is also used to monitor the load voltage value of the first charging load conductively connected to the first charging branch 21. If the load voltage value is greater than the branch voltage value, the control circuit 23 controls the first charging branch 21 to charge a portion of the first charging load based on the load voltage value. This configuration can reduce the power supply pressure on the charging device and prevent the charging device from overheating due to excessive output power, thus protecting the charging device and the first charging load.

[0047] Considering the wear and tear of charging devices or electronic products during use, there is a problem of invalid detection when monitoring operating status parameters. In practical applications, charging devices or electronic products, due to prolonged use and wear to a certain extent, may still detect output voltage even when there is no current input.

[0048] To address this issue, in one embodiment, the operating status parameters include not only the operating temperature parameter but also the branch current parameter. When the first charging mode is activated, the control circuit 23 further monitors the first current parameter of the first charging branch 21. If the first current parameter exceeds a first current threshold, the control circuit 23 controls the first charging branch 21 to charge a portion of the first charging load. Alternatively, when the second charging mode is activated, the control circuit 23 further monitors the second current parameter of the second charging branch 22. If the second current parameter exceeds a second current threshold, the control circuit 23 controls the second charging branch 22 to charge a portion of the second charging load.

[0049] This embodiment uses the current value as the operating status parameter. It reads the input and output voltage values ​​of the charging branch, and obtains the sampling resistor value. Based on these values, the current value of the charging branch is calculated. This setup ensures the effectiveness of the detection by detecting the current value of the charging branch to determine if there are potential faults in the charging device.

[0050] For example, Figure 6 A schematic diagram of current detection is provided. (For example...) Figure 6As shown, the control circuit 23 includes a voltage / current detection chip U. Assuming the control circuit 23 reads the input voltage value Vi and output voltage value Vo of the first charging branch 21 or the second charging branch 22, and obtains the sampling resistor value Rs, then the current value I = (Vi - Vo) / Rs. Furthermore, to facilitate the computer's reading of the current value, it can be converted using the formula: Cal = turnc[2^15 × 0.04096 / (Rs × I)]. For example, if I = 0.0001A and Rs = 0.1Ω, then Cal = 4096 = 0 × 1000.

[0051] In one embodiment, when the first charging mode is activated, the control circuit 23 is also used to monitor the power value of the first charging load. If the power value is not lower than the power threshold, the control circuit 23 controls the first charging branch 21 to stop charging the first charging load and switches the first charging mode to the second charging mode.

[0052] In this embodiment, if the power level of the first charging load is not lower than a power threshold (e.g., 80%–100%), it indicates that the electronic product has completed its charging task. After the higher-priority electronic product completes its task, the control circuit 23 can disconnect the first charging branch and restore the power supply to the second charging branch; or, it can turn off the voltage output of the first charging branch and restore the voltage output of the second charging branch, thereby opening up the remaining available charging resources to meet the charging needs of lower-priority electronic products. This configuration, when the charging device cannot charge multiple electronic products simultaneously, converts the charging needs of each electronic product to be met sequentially in a serial manner, increasing the flexibility of the charging mode.

[0053] In practical applications, such as Figure 6 As shown, the control circuit 23 also includes a communication interface IIC, which is used to connect to the terminal device. The voltage / current detection chip U sends the detected charging status (including power level and charging progress) of each electronic product to the terminal device through the communication interface IIC, allowing users to remotely view the charging status of the electronic products.

[0054] In one embodiment, Figure 7 A schematic diagram of another charging management circuit is provided. (For example...) Figure 7 As shown, the charging management circuit 2 also includes a charging trunk line 25, which is connected to the first charging branch line 21 and the second charging branch line 22. When the second charging mode is started, the control circuit 23 is also used to monitor the third current parameter of the charging trunk line 25. When the third current parameter exceeds the third current threshold, the control circuit 23 switches the second charging mode to the first charging mode.

[0055] In this embodiment, when the second charging mode is activated, if the control circuit 23 detects that the third current parameter (the sum of the current parameters of multiple charging branches) of the charging trunk 25 exceeds the third current threshold, then the control circuit 23 switches the second charging mode to the first charging mode. Specifically, it controls the first charging branch 21 to charge part or all of the first charging load, and controls the second charging branch 22 to suspend charging the second charging load. This configuration protects the charging equipment and electronic products while meeting the usage needs of some electronic products.

[0056] In one embodiment, a combined charging device is provided. Figure 8 This is a schematic diagram of the combined charging device in this embodiment. Figure 8 As shown, multiple charging devices are combined and installed as a single unit to form a combined charging device. Each charging device contains... Figure 2 The base 1 shown has a first inclined portion 13 and a second inclined portion 14. A first charging slot 11 is disposed on the first inclined portion 13, and a second charging slot 12 is disposed on the second inclined portion 14. Embodiments of the charging management circuit have been described in the above embodiments and will not be repeated in this embodiment.

[0057] In this embodiment, the combined charging device can charge multiple first charging loads and / or second charging loads simultaneously. Each charging device is divided into a first charging load and a second charging load based on the charging power of the wearable electronic product, and a first charging mode and a second charging mode are set according to the first charging load and the second charging load, wherein the charging power of the first charging load is less than that of the second charging load. Considering that the first charging load has a higher charging priority (higher usage frequency, lower charging power), and that disconnecting the first charging load provides less remaining charging resources than disconnecting the second charging load, this embodiment adopts a tiered charging control method. In both the first charging mode and the second charging mode, the charging needs of the first charging load are prioritized to varying degrees. This ensures that if the charging device needs to shut down due to full load operation or potential high temperature, only a portion of the charging branches need to be shut down, thus eliminating potential faults and achieving intelligent charging while still allowing some wearable electronic products to function normally.

[0058] In one embodiment, based on the same inventive concept as the aforementioned charging device or combined charging device, an intelligent centralized charging method is provided, which can be applied to the aforementioned charging device or combined charging device. Figure 9 The flowchart of the centralized charging method in this embodiment is as follows: Figure 9 As shown, the process includes the following steps:

[0059] Step S101: Detect the operating status parameters of the charging circuit.

[0060] The charging device includes a charging circuit, which comprises multiple charging branches, such as a first charging branch and a second charging branch. These charging branches are used to charge electronic products. A detection device can be installed in the charging device to monitor the operating status parameters of the charging branches, which can be current or voltage values. The electronic products include, but are not limited to, HUBs (medical electronic watches), ECG (electrocardiogram) devices, and blood pressure monitoring devices.

[0061] Step S102: Determine whether the working status parameters meet the first preset condition.

[0062] The first preset condition can be divided into two cases: the operating state parameter of any charging branch exceeds a first threshold; or, the sum of the operating state parameters of multiple charging branches exceeds a second threshold. The charging circuit may further include a charging main circuit, with multiple charging branches connected to the charging main circuit respectively, the multiple charging branches connected in parallel, and the sum of the operating state parameters of the multiple charging branches equal to the operating state parameter of the charging main circuit.

[0063] If the operating status parameters meet the first preset condition, it indicates that the charging equipment is operating at full load or may experience continuous temperature rise, indicating a potential malfunction. If the current or voltage value of any charging branch exceeds the first current threshold or the second current threshold, or if the current or voltage value of the charging main circuit exceeds the second threshold, it indicates that the charging equipment is operating at full load or may experience continuous temperature rise. If measures are not taken in time, safety issues will arise.

[0064] Step S103: If it is determined that the working status parameters meet the first preset condition, the charging function of the second charging branch is turned off, wherein the charging priority of the first charging branch is higher than the charging priority of the second charging branch.

[0065] Each electronic product uses an independent charging branch for charging, and each charging branch has a corresponding charging priority. The charging priority can depend on the usage frequency of the electronic product, the charging power, or the state of charge. For example, the higher the usage frequency of the electronic product, the higher the charging priority of the corresponding charging branch, and vice versa. For example, the lower the charging power of a charging branch, the higher its charging priority. For example, the higher the percentage of charge a product has, the higher the charging priority of the corresponding charging branch, and vice versa. Disabling the charging function of the second charging branch can be achieved by the power supply stopping power to the second charging branch, or by shutting down the voltage output of the second charging branch; this embodiment is not limited to these methods.

[0066] In steps S101 to S103 above, the working status parameters of the charging circuit are detected during the charging process of the charging device for electronic products. When the working status parameters meet the first preset condition, that is, when the charging device is running at full load or there is a risk of high temperature, only some charging branches are shut down according to the charging priority, so that some charging branches in the charging device are still working. In this way, potential faults are eliminated while ensuring the normal use of some electronic products, and intelligent charging of the charging device is realized.

[0067] In one embodiment, before detecting the operating status parameters of the charging circuit, the method further includes: detecting the temperature of the charging device; determining whether the temperature meets a second preset condition; and triggering an alarm if the temperature meets the second preset condition.

[0068] In this embodiment, the temperature of the charging device is detected before detecting the operating status parameters of the charging circuit. If the temperature of the charging device is found to be high, an alarm is triggered, and the operating status parameters of the charging circuit are further detected. This setting can, on the one hand, remind the user to pay attention to the current operating status of the charging device, and on the other hand, the charging device will not directly cut off the power supply. Instead, through the above steps S101 to S103, potential faults are eliminated while ensuring the normal use of some electronic products, thus realizing intelligent charging of the charging device.

[0069] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0070] In one embodiment, the second preset condition can be divided into two cases: the ambient temperature of the charging device exceeds a third threshold; or, the circuit board temperature of the charging device exceeds a fourth threshold. These two temperatures can be detected individually or in combination. In practical applications, when the charging device is fully loaded, the circuit board temperature and the main power chip temperature will become high. If encountering harsh ambient temperatures while still needing to power critical equipment, the following methods can be adopted. Figure 10 A flowchart of a centralized charging method according to this embodiment is provided, such as... Figure 10 As shown, the process includes the following steps:

[0071] Step S201: Detect the ambient temperature;

[0072] Step S202: Determine whether the ambient temperature is lower than the third threshold (e.g., 45°C); if yes, proceed to step S202; otherwise, proceed to step S210.

[0073] Step S203: Detect the board temperature;

[0074] Step S204: Determine whether the board temperature is below the fourth threshold (e.g., 70°C); if yes, proceed to step S205; otherwise, proceed to step S210.

[0075] Step S205: Detect the current in the charging branch;

[0076] Step S206: Determine whether the current of the charging branch is lower than the first threshold (e.g., 1A); if yes, proceed to step S207; otherwise, proceed to step S210.

[0077] Step S207: Detect the current in the charging main circuit;

[0078] Step S208: Determine whether the current of the charging main circuit is lower than the second threshold (e.g., 8A); if yes, proceed to step S209; otherwise, proceed to step S210.

[0079] Step S209: Maintain the charging function of the currently running charging branch;

[0080] Step S210: Trigger the alarm;

[0081] Step S211: Turn off the charging function of the second charging branch.

[0082] This embodiment combines temperature detection of the charging equipment with the detection of operating parameters of the charging circuit to automatically warn of potential faults or abnormalities, reducing the risk of equipment damage. It formulates personalized charging strategies based on the battery type and charging needs of different devices. According to the urgency and usage frequency of the devices, it intelligently allocates charging priorities, optimizes charging time and power usage, extends battery life, reduces energy consumption, and lowers operating costs. Furthermore, while ensuring the normal use of some electronic products, it automatically eliminates potential faults, achieving intelligent charging of the equipment.

[0083] In one embodiment, before detecting the operating state parameters of the charging circuit, the method further includes: responding to an in-situ signal received by the charging branch; controlling the output voltage of the charging branch. For example... Figure 3As shown, the base 1 is equipped with an presence detection unit 15, which is used to detect whether the first charging load is placed in the first charging slot 11 and whether the second charging load is placed in the second charging slot 12. The presence detection unit 15 can detect whether the electronic product is correctly connected to the corresponding charging branch. When the presence detection unit 15 detects the presence signal, it will trigger the charging device to turn on the output voltage of the corresponding charging branch. Optionally, the presence detection unit 15 can be a light sensor (detecting light intensity) or a pressure sensor (e.g., a mechanical button), and correspondingly, the presence signal can be a light sensor signal or a pressure sensor signal. This embodiment determines whether an electronic product is connected to the charging branch by detecting the presence signal, and then decides whether to turn on the output voltage of the corresponding charging branch, which can prevent accidental human contact and leakage.
