Description

Technical Field

[0001] The present invention relates to the field of battery charging, and particularly to a charging method for an electronic device, the electronic device, and a medium. Background Art

[0002] Wearable devices, such as bracelets, sports watches, smart watches, etc., are small in size, and their battery capacities are correspondingly small, generally between 100 - 500 mAh, and the charging voltage of the battery is between 2.2 V - 4.2 V. When charging the battery with a voltage lower than 3 V or higher than 4 V, in order to prevent damage to the battery by a large current, the charging current is controlled by a battery management chip, and the battery is charged with the minimum charging current. However, the minimum charging current of existing charging management chips is usually greater than the safe charging current of the battery of the electronic device. For example, the minimum charging current of the charging management chip is 50 mA, and the safe charging current of the battery of the electronic device is 40 mA. Obviously, the minimum charging current of the charging management chip cannot meet the safe charging requirements of the battery of the electronic device. Summary of the Invention

[0003] The embodiments of the present application provide a charging method for an electronic device, the electronic device, and a medium. The charging method of the present application does not require an additional charging protection shunt load circuit, saving the hardware cost and structural space of the electronic device. Moreover, by adjusting the working current of the shunt device, the charging current of the battery of the electronic device can be flexibly and precisely controlled to achieve charging protection for the battery of the electronic device.

[0004] In a first aspect, the embodiments of the present application disclose a charging method for an electronic device, including: the electronic device is in a first charging state; detecting whether a first charging current entering the battery of the electronic device is greater than a preset charging threshold; in the case where it is detected that the first charging current is greater than the preset charging threshold, inputting a partial current of the first charging current into a shunt device of the electronic device, so that a second charging current entering the battery is less than or equal to the preset charging threshold, where the shunt device is further used to perform a first function of the electronic device.

[0005] For example, when the first charging state is that the battery voltage is less than a low voltage threshold or higher than a high voltage threshold, or the ambient temperature is less than zero degrees Celsius, the first charging current is the minimum charging current of the charging management chip, the shunt device is a PPG sensor, and then the coulomb meter detects the actual charging current I1 flowing into the battery in real time and feeds the actual charging current I1 back to the controller. The controller determines whether the actual charging current is within the current threshold. If the actual charging current is greater than the current threshold, where the current threshold is 0.1 times the battery capacity, the controller consumes a partial current I2 of the charging current I in through controlling the bypass PPG sensor, and satisfies the following relationship:

[0006] I in = I1 + I2

[0007] As can be seen from the above formula, when I in is constant, by adjusting I2, that is, adjusting the working current of the PPG sensor, the actual charging current flowing into the battery can be kept within the current threshold. In order for the battery to be charged safely and quickly, the actual charging current can be made equal to the current threshold.

[0008] In one implementation of the above first aspect, the method further includes: when the charging condition of the electronic device meets the preset charging condition, charging the electronic device in the second charging state; when the charging condition of the electronic device does not meet the preset charging condition, charging the electronic device in the first charging state; wherein, the charging current entering the battery in the second charging state is greater than the charging current entering the battery in the first charging state.

[0009] In one implementation of the above first aspect, meeting the preset charging condition includes at least one of the following: the voltage of the battery is greater than the first voltage threshold and less than the second voltage threshold, where the second voltage threshold is greater than the first voltage threshold; the ambient temperature of the battery is greater than the temperature threshold.

[0010] In one implementation of the above first aspect, the method includes: the first voltage threshold is 3V, the second voltage threshold is 4V, and the temperature threshold is zero degrees Celsius. For example, the voltage of a lithium battery is generally between 2.2V and 4.2V. If the voltage of the lithium battery is below 3V, it means that the battery power of the lithium battery is low. If the voltage of the lithium battery is above 4V, it means that the battery power of the lithium battery is high. If a large current is used to directly charge the lithium battery at this time, it will damage the lithium battery. A small current must be used to charge the lithium battery. In addition, when the ambient temperature is less than zero degrees Celsius, directly charging the lithium battery with a large current will also damage the lithium battery. Therefore, in the embodiments of the present application, the first voltage threshold can be set to 3V, the second voltage threshold can be set to 4V, and the temperature threshold can be set to zero degrees Celsius.

[0011] In one implementation of the above first aspect, the method includes: the preset charging threshold is numerically equal to 0.1 times the battery capacity of the battery. For example, the preset charging threshold of the battery can be set to 0.1C, where C is the charging rate, which represents the current value required for the battery to charge its rated capacity within a specified time, and it is numerically equal to a multiple of the battery rated capacity.

[0012] In one implementation of the first aspect described above, the step of inputting a partial current of the first charging current into a shunt device of the electronic device so that the second charging current entering the battery is less than or equal to the preset charging threshold includes: determining the difference between the first charging current and the preset charging threshold; inputting a partial current greater than or equal to the difference into the shunt device so that the second charging current entering the battery is less than or equal to the preset charging threshold.

[0013] In one implementation of the first aspect described above, the shunt device is a photoplethysmography (PPG) sensor.

[0014] In one implementation of the first aspect described above, the photoplethysmography (PPG) sensor includes a light-emitting diode; and the step of inputting a partial current of the first charging current into a shunt device of the electronic device so that the second charging current entering the battery is less than or equal to the preset charging threshold includes: adjusting the operating current of the light-emitting diode of the photoplethysmography (PPG) sensor so that the operating current of the light-emitting diode is greater than or equal to the difference.

[0015] For example, the preset charging threshold of the battery is 10 mA, and the actual charging current is 50 mA. According to the above formula, it can be known that the PPG sensor needs to shunt 40 mA. Then, the controller sends a command to the PPG sensor to start the operation of the PPG sensor. The LED of the PPG sensor emits light of a specific wavelength, for example, green light. Then, the controller adjusts the light-emitting intensity of the LED of the PPG sensor so that the operating current at this light-emitting intensity is 40 mA. Alternatively, start the operation of the PPG sensor, and then the controller adjusts the wavelength of the light emitted by the LED of the PPG sensor so that the current required for the light of this wavelength is 40 mA.

[0016] In one implementation of the first aspect described above, the photoplethysmography (PPG) sensor is further configured to perform at least one of the following functions of the electronic device: measuring the user's heart rate; measuring the user's blood oxygen saturation.

[0017] In one implementation of the first aspect described above, the shunt device includes a motor. For example, the controller can adjust the rotation speed of the motor by controlling the operating current of the motor. Moreover, the greater the operating current of the motor, the faster the rotation speed of the motor, and the smaller the operating current of the motor, the slower the rotation speed of the motor. When the actual charging current of the battery is greater than the preset charging threshold, the controller realizes shunting by controlling the operating current of the motor, so that the charging current input into the battery is within the preset charging current.

[0018] In one implementation of the first aspect described above, the first function performed by the motor for the electronic device is: generating a vibration prompt.

[0019] Second aspect, embodiments of the present application disclose an electronic device, including:

[0020] A current detection device for detecting whether a first charging current entering the battery of the electronic device is greater than a preset charging threshold;

[0021] A charging management chip for, when detecting that the first charging current is greater than the preset charging threshold, inputting a partial current of the first charging current into a shunt device of the electronic device, so that a second charging current entering the battery is less than or equal to the preset charging threshold;

[0022] A shunt device for, when detecting that the first charging current is greater than the preset charging threshold, receiving a partial current of the first charging current, so that the second charging current entering the battery is less than or equal to the preset charging threshold; for example, the shunt device may be a PPG sensor or a motor, etc.

[0023] A memory for storing instructions executed by one or more controllers of the electronic device, and

[0024] A controller for controlling the current detection device, the charging management chip, and the shunt device to execute the charging method of the electronic device described in the first aspect above.

[0035] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention, rather than limiting the embodiments of the present invention. In addition, only a part of the structure related to the embodiments of the present invention is shown in the drawings, rather than all the structures.

[0036] Next, the technical solutions of the embodiments of the present application will be further described in detail through the drawings and embodiments.

[0037] Figure 1 A charging scenario diagram 10 of an electronic device provided by a specific embodiment of the present application is shown. As Figure 1 shown, the battery power of the electronic device is very low. For example, the battery power of the electronic device only remains 10%. The power supply 200 charges the battery of the electronic device. When the battery power of the electronic device is low, the charging current must be controlled within a safe current at this time to protect the battery of the electronic device. In order to ensure that the charging current of the electronic device is within the safe current, the embodiments of the present application perform bypass shunting through internal devices of the electronic device, such as a PPG (photoplethysmograph) sensor, a motor, etc. When the charging current is greater than the safe current of the battery of the electronic device, the working current of the PPG sensor is adjusted to consume a part of the charging current, so that the actual current flowing into the battery of the electronic device is within the safe current. The embodiments of the present application do not need to add an additional charging protection shunt load circuit, saving the hardware cost and structural space of the electronic device. Moreover, by adjusting the working current of the PPG sensor, the charging current of the battery of the electronic device can be flexibly and accurately controlled, realizing the charging protection of the battery of the electronic device.

[0038] For the convenience of description, the technical solutions of the present application will be introduced below by taking the PPG sensor as an example.

[0039] It can be understood that Figure 1As shown, the electronic device is charged by wired charging. In other embodiments of the present application, the electronic device can also be charged by wireless charging. The wireless charging methods include but are not limited to electromagnetic induction, electromagnetic resonance, electric field coupling, and radio wave methods, which are not limited herein.

[0040] In specific embodiments of the present application, the electronic device can be various devices, including but not limited to bracelets, sports watches, smart watches, or wearable electronic devices such as glasses, helmets, headbands, and medical detection instruments. In the following description, for simplicity of explanation, the bracelet 100 is taken as an example to illustrate the technical solution of the present application.

[0041] Figure 2 Shown is a schematic diagram of the hardware structure of a bracelet 100 provided according to some embodiments of the present application. As Figure 2 shown, the bracelet 100 can include a bracelet body. In one embodiment of the present application, the main body of the bracelet 100 can include a touch screen 101 (also known as a touch panel), a display screen 102, a housing (the housing includes a front shell ( Figure 2 not shown) and a bottom shell ( Figure 2 not shown), as well as a controller 103, a memory 104, a PPG sensor 105, a charging management chip 106, a coulomb meter 107, and a battery 108, etc.

[0042] The following separately introduces each functional component of the bracelet 100:

[0043] The touch screen 101, also known as a touch panel, can collect the touch operations of the bracelet user thereon (such as the operations of the user using a finger, a stylus, or any suitable object or accessory on or near the touch panel).

[0044] The display screen 102 can be used to display the information input by the user, the prompt information for the user, and various menus on the bracelet. Further, the touch panel 101 can cover the display screen 102. When the touch panel 101 detects a touch operation on or near it, it is transmitted to the controller 103 to determine the type of touch event. Subsequently, the controller 103 provides a corresponding visual output on the display screen 102 according to the type of touch event. In some embodiments of the present application, the display screen 102 can display the remaining battery power of the battery 108. For example, the display screen 102 shows that the battery 108 has 10% remaining power, reminding the user to charge the bracelet 100.

[0045] The controller 103 is the control center of the smart bracelet 100. It can be one or more general-purpose central processing units, microprocessors, etc., or it can be an application-specific integrated circuit (ASIC), electronic circuit, etc. In some embodiments of the present application, the controller 103 can control the charging current of the charging management chip 106 and the working current of the PPG sensor 105 according to the battery voltage or ambient temperature, and can also receive the current signal detected by the coulomb meter 107.

[0046] The memory 104 is used to store software programs and data. The controller 103 executes various functional applications and data processing of the smart bracelet 100 by running the software programs and data stored in the memory 104.

[0047] The PPG sensor 105 mainly consists of three parts of circuits: a light-emitting diode (LED), a photodiode, and a signal processing / compensation circuit. Among them, the working current of the LED is between 0 and 100 mA, and the controller 103 can adjust the light-emitting intensity of the LED by adjusting the working current of the LED. The working principle of the PPG sensor is that the LED emits light of a certain wavelength (usually green light when measuring heart rate), and then the photodiode measures the intensity of the emitted / transmitted light. Since only the reflection of light by blood is a fluctuating value, the frequency of this fluctuation is the pulse, and the fluctuation frequency is consistent with the heart rate. In addition, the PPG sensor 105 is also used to measure the blood oxygen saturation of the user.

[0048] The charging management chip 106 supports a USB interface input source with a voltage range of 3.9V - 14V, and can automatically identify various input sources, including USB SDP, CDP, DCP, non-standard adapters, adjustable high-voltage adapters. After identifying the input source, it can set the input current limit according to the input source to prevent large currents from damaging the circuit or the lithium battery (battery 108).

[0049] The coulomb meter 107 is used to accurately track the power change of the battery 108. A current detection resistor is connected in series with the positive or negative electrode of the battery 108. Once there is current flowing into or out of the battery 108, a voltage will be generated across the two ends of the resistor. By detecting the voltage, the current flowing through the battery 108 can be calculated. The integral of the current with respect to time is the changing power, so the power change can be accurately tracked with an accuracy of up to 1%. In the embodiments of the present application, the coulomb meter 107 can obtain the current of the battery 108 in real time and feedback the obtained current value to the controller 103.

[0050] The battery 108 is used to power the components within the bracelet 100. In some embodiments of the present application, the battery 108 is a lithium battery and can be repeatedly charged. Among them, a lithium battery is a type of battery with metal lithium or a lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. Due to the high chemical activity of metallic lithium, the lithium battery needs to be protected during the charging of the battery 108.

[0051] It can be understood that Figure 2 The structure shown is merely a specific structure for implementing the functions of the bracelet 100 in the technical solution of the present application. Bracelets 100 with other structures and capable of achieving similar functions are also applicable to the technical solution of the present application, and are not limited herein.

[0052] Next, in combination with specific scenarios, the technical solution of the present application will be introduced in detail.

[0053] As Figure 3 shown, when the DC power supply charges the battery 108, the controller 103 can control the charging current I of the charging management chip 106 according to the ambient temperature or the battery voltage in . For example, when the battery voltage is less than the low voltage threshold or higher than the high voltage threshold, or the ambient temperature is less than zero degrees Celsius, the controller 103 can control the charging management chip 106 to charge with the minimum charging current through I2C (inter-integrated circuit, two-wire serial bus). The coulomb meter 107 real-time detects the actual charging current I1 flowing into the battery 108 and feeds back the actual charging current I1 to the controller 103 through the I2C bus. The controller 103 determines whether the actual charging current is within the current threshold. If the actual charging current is greater than the current threshold, where the current threshold is 0.1 times the battery capacity, the controller 103 controls the bypass PPG sensor 105 to consume a part of the charging current I in of the current I2, and satisfies the following relationship:

[0054] I in =I1 + I2 (1)

[0055] It can be seen from formula (1) that when I in is constant, by adjusting I2, that is, adjusting the working current of the PPG sensor 105, the actual charging current flowing into the battery 108 can be kept within the current threshold. In order for the battery 108 to be safely and quickly charged, the actual charging current can be made equal to the current threshold.

[0056] It can be understood that Figure 3The communication bus in

[0057] is not limited to I2C and SPI, and can also be other buses. For example, UART (Universal Asynchronous Receiver / Transmitter) is not restricted here. In addition, the communication connection method is not limited. For example, the PPG sensor 105 can also be connected to the controller 103 through the I2C bus, and the charge management chip 106 and the coulomb meter 107 can also be connected to the controller 103 through the SPI bus. Figures 4a - 4c Next, according to some embodiments of the present application, the technical solution of the present application will be specifically described as follows:

[0058] Figure 4a The flowchart showing the technical solution of the present application is as Figure 4a shown and includes:

[0059] a401: The bracelet 100 is connected to a DC power supply. In some embodiments of the present application, the DC power supply can be a USB power supply or an adapter power supply, which is not restricted here.

[0060] a402: The controller 103 determines whether the voltage of the battery 108 is less than the low voltage threshold;

[0061] The voltage of the battery 108 reflects the power situation. The lower the voltage, the lower the power of the battery. For example, the battery 108 is a lithium battery, and the voltage of the lithium battery of the electronic device is generally between 2.2V and 4.2V. If the voltage of the lithium battery is below 3.0V, it means that the power of the lithium battery is low. If the lithium battery is directly charged with a large current at this time, it will damage the lithium battery, and the lithium battery must be charged with a small current. In some embodiments of the present application, the low voltage threshold of the battery 108 can be set to 3.0V.

[0062] If the voltage of the battery 108 is less than the low voltage threshold, then a404 is executed; otherwise, a403 is executed;

[0063] a403: The controller 103 controls the charge management chip 106 to charge the battery 108 with the current charging current. It can be understood that if the battery voltage is greater than the low voltage threshold and less than the high voltage threshold, the battery 108 can be quickly charged with a large current at this time.

[0064] a404: The controller 103 controls the charge management chip 106 to charge with the minimum charging current;

[0065] In some embodiments of the present application, the charging management chip 106 can be any type of charging management chip. For example, as shown in Table 1, the charging management chip 106 can be RT9471, BQ25601, or SGM41511, and the minimum charging current can be represented by the minimum value, typical value, or maximum value. Among them, the charging management chip 106 can divide the charging current into multiple gears, and the current difference between the gears is relatively large. The minimum charging current is the lowest gear. For example, the charging management chip RT9471 can divide the charging current into 3 gears. The lowest gear is the minimum charging current of 50 mA, and the other gears can be 100 mA and 150 mA.

[0066]

[0067] Table 1. Minimum Charging Current of Charging Management Chip

[0068] For the convenience of description, in the embodiments of the present application, the typical value of the minimum charging current is used as the minimum charging current. Taking the charging management chip 106 as RT9471 as an example, its minimum charging current is 50 mA. It can be understood that in other embodiments of the present application, the minimum value or maximum value of the minimum charging current can also be used as the minimum charging current of the charging management chip 106, which is not limited here.

[0069] a405: The coulomb meter 107 detects the actual charging current flowing into the battery 108 and feeds back the detected actual charging current to the controller 103.

[0070] a406: The controller 103 determines whether the actual charging current is less than the current threshold;

[0071] In some embodiments of the present application, the current threshold of the battery 108 can be set to 0.1C, where C is the charging rate, which represents the current value required for the battery to charge its rated capacity within a specified time, and it is numerically equal to the multiple of the battery rated capacity. The current thresholds of the batteries of different electronic devices may be different. For example, as shown in Table 2, if the electronic device is a bracelet, its rated battery capacity may be 100 mAh, then the current threshold (0.1C) is 10 mA; if the electronic device is a sports watch, its rated battery capacity may be 450 mAh, then the current threshold (0.1C) is 45 mA; if the electronic device is a smart watch, its rated battery capacity may be 600 mAh, then the current threshold (0.1C) is 60 mA.

[0072] It should be noted that in the embodiments of the present application, the current threshold is set to 0.1C based on the IEC62368 (International Product Safety Standard) certification standard. Regarding the charging accuracy, the requirements of the battery specification sheet need to be met, and a maximum charging current of 0.1C is required during trickle or low-temperature charging. In other embodiments of the present application, the current threshold can also be set to other values, which are not limited herein.

[0073]

[0074] Table 2. Charging required current of different electronic devices

[0075] Obviously, as can be seen from Table 1 and Table 2, on electronic devices such as smart bracelets and sports bracelets, the charging management chip cannot meet the charging current requirement of 0.1C.

[0076] If the actual charging current is less than the current threshold, then a402 is executed, and the controller 103 determines whether the battery voltage is less than the low-voltage threshold to achieve real-time monitoring of the battery voltage, so that the actual charging current remains below the current threshold;

[0077] If the actual charging current is greater than the current threshold, then a407 is executed;

[0078] a407: The controller 103 controls the PPG sensor 105 to perform shunt;

[0079] For example, the charging management chip 106 is RT9471, its minimum charging current is 50mA, the rated battery capacity of the smart bracelet 100 is 100mAh. According to the safe current required for 0.1C charging, the charging rate C is numerically equal to the battery capacity. Then the current threshold of the battery 108 can be set to 0.1C, that is, the current threshold of the battery 108 is 10mA, and the working current of the PPG sensor 105 is between 0 - 100mA. At this time, the actual charging current is the minimum charging current (50mA), which is greater than the current threshold of the battery 108 (10mA), and the controller 103 controls the PPG sensor to work at the corresponding current.

[0080] In some embodiments of the present application, the controller 103 adjusts the luminous intensity of the LED of the PPG sensor 105 to adjust the working current of the PPG sensor 105.

[0081] For example, since the threshold of the battery 108 is 10 mA and the actual charging current is 50 mA, according to formula (1), it can be known that the PPG sensor 105 needs to shunt 40 mA. Then, the controller 103 sends an instruction to the PPG sensor 105 to start the operation of the PPG sensor 105, and the LED of the PPG sensor 105 emits light of a specific wavelength, for example, green light. Then, the controller 103 adjusts the light emission intensity of the LED of the PPG sensor 105 so that the working current at this light emission intensity is 40 mA. It can be understood that the greater the current, the greater the light emission intensity.

[0082] In some embodiments of the present application, the controller 103 adjusts the light emission wavelength of the LED of the PPG sensor 105 to adjust the working current of the PPG sensor 105.

[0083] For example, since the threshold of the battery 108 is 10 mA and the actual charging current is 50 mA, according to formula (1), it can be known that the PPG sensor 105 needs to shunt 40 mA. Then, the controller 103 sends an instruction to the PPG sensor 105 to start the operation of the PPG sensor 105, and then the controller 103 adjusts the light emission wavelength of the LED of the PPG sensor 105 so that the current required for the light of this wavelength is 40 mA.

[0084] It can be understood that the shorter the wavelength, the greater the energy consumed and the greater the current required. For example, under the same light intensity, the current of the red light wavelength may be 10 mA, and the current of the green light wavelength may be 40 mA.

[0085] In addition, during the charging process, due to factors such as wire loss or device detection error, the actual charging current of the battery 108 may change. The coulomb meter 107 detects the actual charging current of the battery 108 in real time and feeds the detected actual charging current back to the controller 103. If the actual charging current is greater than the current threshold, the controller 103 adjusts the working current of the PPG sensor 105 in real time.

[0086] For example, the sampling frequency of the coulomb meter 107 is 50 Hz, that is, the coulomb meter 107 detects the actual charging current of the battery 108 50 times per second. For example, the actual charging currents detected by the coulomb meter 107 in the first 48 times are equal to the current threshold (10 mA), and the actual charging current detected in the 49th time is 15 mA, which is greater than the current threshold. The coulomb meter 107 feeds the current value of 15 mA back to the controller 103, and the controller 103 controls the PPG sensor 105 to increase the working current of the LED by another 5 mA. Then, the coulomb meter 107 detects the actual charging current of the battery 108 in the 50th time to be 10 mA, within the safe charging range.

[0087] The charging management chip 106 charges with the minimum charging current, and the power of the battery 108 continuously increases until the battery voltage reaches the low voltage threshold. At this time, the charging management chip 106 can switch to a high current gear to charge the battery 108, which will not be elaborated here.

[0088] Figure 4a A charging protection scheme when the voltage of the battery 108 is relatively low is introduced. If the battery 108 is almost fully charged, at this time the voltage of the battery 108 is relatively high, and large current charging cannot be continued. The charging current of the battery 108 needs to be controlled within a safe current. Figure 4b Shows a charging protection flowchart when the battery voltage is relatively high, as Figure 4b shown, including:

[0089] b401: The bracelet is connected to a DC power supply (refer to Figure 4a description);

[0090] b402: The controller 103 determines whether the battery voltage is greater than the high voltage threshold;

[0091] The voltage of the battery 108 reflects the power situation. The higher the voltage, the higher the power of the battery. For example, the battery 108 is a lithium battery, and the voltage of the lithium battery of the electronic device is generally between 2.2V - 4.2V. If the voltage of the lithium battery is above 4.0V, directly charging the lithium battery with a large current at this time will damage the lithium battery, and it must be charged with a small current. In some embodiments of the present application, the high voltage threshold of the battery 108 can be set to 4.0V.

[0092] If the battery voltage is greater than the high voltage threshold, then execute b404; otherwise, execute b403;

[0093] b403: The controller 103 controls the charging management chip 106 to charge the battery 108 with the current charging current; if the battery voltage is greater than the low voltage threshold and less than the high voltage threshold, at this time the battery 108 can be quickly charged with a large current.

[0096] b406: The controller 103 determines whether the actual charging current is less than the current threshold (for the specific process, please refer to Figure 4a description);

[0097] If the actual charging current is less than the current threshold, then b402 is executed, and the controller 103 determines whether the battery voltage is greater than the high-voltage threshold, so as to monitor the battery voltage in real time and keep the actual charging current below the current threshold;

[0098] If the actual charging current is greater than the current threshold, then b407 is executed;

[0099] b407: The controller 103 controls the PPG sensor 105 to shunt (for the specific process, please refer to Figure 4a the description).

The temperature threshold can be set to zero degrees Celsius, because when the electronic device is charged below zero degrees Celsius, if the electronic device is charged with a large current, it will damage the battery.

[0103] If the ambient temperature is less than the temperature threshold, then b404 is executed; otherwise, 403 is executed;

[0104] c403: The controller 103 controls the charging management chip 106 to charge the battery 108 with the current charging current; if it is greater than the temperature threshold, at this time, the battery 108 can be quickly charged with a large current.

[0105] c404: The controller 103 controls the charging management chip 106 to charge with the minimum charging current (for the specific process, please refer to Figure 4a the description);

[0106] c405: The coulomb meter 107 detects the actual charging current flowing into the battery 108 and feeds back the detected actual charging current to the controller 103 (for the specific process, please refer to Figure 4a the description).

[0107] c406: The controller 103 determines whether the actual charging current is less than the current threshold (for the specific process, please refer to Figure 4a the description);

[0108] If the actual charging current is less than the current threshold, then execute c402; the controller 103 determines whether the ambient temperature is less than the temperature threshold, to achieve real-time monitoring of the ambient temperature, so that the actual charging current is kept below the current threshold;

[0109] If the actual charging current is greater than the current threshold, then execute c407;

[0110] c407: The controller 103 controls the PPG sensor 105 to shunt (for the specific process, please refer to Figure 4a the description).

[0112] d401: The bracelet is connected to a DC power supply (refer to Figure 4a the description);

[0113] d402: The controller 103 determines whether the battery voltage or the ambient temperature meets the preset conditions;

[0114] In some embodiments of the present application, the preset conditions include at least one of the battery voltage being less than the low voltage threshold, the battery voltage being greater than the high voltage threshold, or the ambient temperature being less than the temperature threshold.

[0116] The battery voltage is greater than 4V;

[0117] The ambient temperature is below zero degrees Celsius.

[0118] If the ambient temperature or the battery voltage meets the preset conditions, then execute d404; otherwise, execute d403;

[0119] For example, if the current ambient temperature is minus 2 degrees Celsius and the battery voltage is 2.5V, then the preset conditions are met and d404 is executed.

In the embodiments of the present invention, taking the Android system with a layered architecture as an example, the software structure of the terminal device is exemplarily described. Figure 6 It is the software structure block diagram of the terminal device in the embodiments of the present invention.

[0151] The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces.

For example, it prompts text information in the status bar, emits a prompt tone, the terminal device vibrates, the indicator light flashes, etc.

[0162] Android runtime includes the core libraries and the virtual machine. Android runtime is responsible for the scheduling and management of the Android system.

[0163] The core libraries contain two parts: one part is the functional functions that need to be called by the Java language, and the other part is the core libraries of Android.

[0164] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as the management of object life cycles, stack management, thread management, security and exception management, and garbage collection.

[0165] The system libraries can include multiple functional modules. For example: surface manager, Media Libraries, 3D graphics processing library (such as: OpenGL ES), 2D graphics engine (such as: SGL), etc.
