Attached Figure Description

[0020] Figure 1 This is a schematic diagram of a high-voltage battery assembly, a motherboard, and an electronic device for identifying the battery charging state, according to one embodiment. Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0022] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0023] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0024] High-voltage batteries (such as those with a full charge voltage of 8V) are typically used for special functions that require higher voltage to operate (such as fast charging, high-power devices, etc.). When mobile phones and other electronic devices use such high-voltage battery components (such as batteries with a full charge voltage greater than a preset voltage threshold), they cannot be charged using conventional Type-C methods (such as those conforming to the "USB Type-C" standard, interface, or connector). Therefore, they need to be charged using external special charging equipment. In this case, mobile phones and other electronic devices cannot detect the charging status of the high-voltage battery component, and thus cannot display the charging status on the screen.

[0025] To address the aforementioned technical deficiencies of high-voltage batteries, the present application proposes the following technical concept: A preset voltage generation module is added within the high-voltage battery assembly to reduce the charging voltage applied to the high-voltage battery assembly by the external power source to 5V, and this 5V voltage is used as the preset voltage signal. This preset voltage generation module only generates the 5V voltage when the high-voltage battery assembly is being charged by an external power source (such as an external special charging device). The 5V voltage generated by the preset voltage generation module is then directly transmitted to the motherboard of the electronic device through the contacts connecting the high-voltage battery assembly and the electronic device. If the CPU on the motherboard detects this 5V voltage, it indicates that the high-voltage battery assembly is in a charging state, and the electronic device can then indicate this status via a screen and / or indicator lights. When the high-voltage battery assembly is fully charged, the CPU on the motherboard detects that the voltage of the high-voltage battery assembly has reached its maximum value, and can then change the charging display status of the high-voltage battery assembly via a screen and / or indicator lights.

[0026] The technical solution of this application will be described in detail below with reference to the embodiments.

[0027] This application provides a high-voltage battery assembly. Please refer to... Figure 1 The high-voltage battery assembly B includes:

[0028] Battery body ( Figure 1 (Not shown in the image) The full-charge voltage of the battery body is greater than the preset voltage threshold.

[0029] The battery body has a charging pin 100 and a discharging pin that are electrically connected to the battery body. The battery body supplies power to the electronic device A through its discharging pin and is charged through its charging pin 100.

[0030] The preset voltage generation module 200 is electrically connected to the charging pin 100. It is used to convert the charging voltage applied by the external power source into a preset voltage signal when the external power source charges the battery body through the charging pin 100, and send the preset voltage signal to the control unit of the electronic device A. The preset voltage signal is used to indicate to the control unit that the battery body is currently in a charging state (such as when the external power source charges the high-voltage battery assembly through the charging pin 100).

[0031] In some embodiments, the control unit includes a CPU.

[0032] It is understandable that those skilled in the art can determine the preset voltage threshold and the specific CPU signal according to the actual application scenario requirements. For example, the preset voltage threshold could be 6V, etc.

[0033] In some embodiments, the high-voltage battery assembly also includes control circuitry for detecting whether the battery cells are supplying power to the electronic device.

[0034] The preset voltage signal in this application is 5V.

[0035] It should be noted that the reasons for using "5V voltage" as the preset voltage signal are as follows: First, to avoid confusion with other communication signals when the motherboard receives the preset voltage signal while the high-voltage battery component is being charged by an external power source through this charging pin; Second, some electronic devices (such as MTK mobile phone chips) have specific logic for their power ICs to detect the charging status, and only when "5V voltage" is supplied to the chip can the charging status be correctly identified; otherwise, there will be a significant difference from the chip's reference circuit design; Third, if this logic is not followed in actual applications, it may require extensive modifications to both software and hardware, including code and circuitry, which would increase complexity and cost, and may introduce unnecessary risks; Fourth, the charging voltage of low-voltage batteries used in mobile phones and other electronic devices is usually 5V, and this design avoids modifications to the conventional detection process, simplifying the design and reducing risks.

[0036] In some embodiments, the preset voltage generation module is a linear regulator; wherein, the input terminal of the linear regulator is electrically connected to the charging pin, and the output terminal of the linear regulator is used to output the preset voltage signal and send the preset voltage signal to the CPU. The output terminal of the linear regulator is electrically connected to the CPU of the electronic device.

[0037] In some embodiments, this input terminal is the power input interface of the linear regulator. Its function is to introduce an unstable external DC power supply into the regulator. The output terminal is the stable voltage output interface of the linear regulator. Its function is to output the regulated stable DC power supply to the external load.

[0038] In some embodiments, the linear regulator also includes an adjustment terminal. The adjustment terminal is the interface in the linear regulator used to adjust the output voltage. By adjusting the resistance or voltage value at this port, the magnitude of the output voltage can be changed.

[0039] In some embodiments, the linear regulator is designated DS8242. This model of linear regulator can convert a charging voltage of approximately 8V to a 5V output voltage.

[0040] In some embodiments, the preset voltage generation module includes a pull-up resistor and a pull-down resistor connected in sequence; wherein, one end of the pull-up resistor is electrically connected to the charging pin, the common terminal of the pull-up resistor and the pull-down resistor is used to output the preset voltage signal, and the other end of the pull-down resistor is grounded. Those skilled in the art can determine the specific resistance values ​​of the pull-up resistor and the pull-down resistor according to actual needs. For example, the resistance value of the pull-up resistor can be 12 kΩ, and the resistance value of the pull-down resistor can be 20 kΩ.

[0041] In some embodiments, a second contact point may be provided on the high-voltage battery assembly. When the second contact point on the high-voltage battery assembly comes into contact with a newly added first contact point on the motherboard, the second contact point can transmit the preset voltage signal generated by the preset voltage generation module to the newly added first contact point on the motherboard. The second contact point can be a pin, spring, ejector pin, or wire bond, etc. The first contact point can also be a pin, spring, ejector pin, or wire bond, etc. The preset voltage signal is then transmitted to the CPU connected to the motherboard through the newly added first contact point on the motherboard.

[0042] As can be seen, in some embodiments, a preset voltage generation module is added to the high-voltage battery assembly of this application to convert the charging voltage applied to the high-voltage battery assembly by the external power source into a low voltage of 5V, and uses this 5V voltage as a preset voltage signal. The preset voltage generation module only generates this 5V voltage when the high-voltage battery assembly is being charged by an external power source (such as an external special charging device). Subsequently, the 5V voltage generated by the preset voltage generation module is directly transmitted to the motherboard of the electronic device through the port (such as a contact) where the high-voltage battery assembly is electrically connected to the electronic device. If the CPU on the motherboard detects this 5V voltage, it indicates that the high-voltage battery assembly is in a charging state, and the electronic device can then indicate that the high-voltage battery assembly is currently charging through the screen and / or indicator lights. When the high-voltage battery assembly is fully charged, the CPU on the motherboard detects that the voltage of the high-voltage battery assembly has reached its maximum value, and can then change the charging display status of the high-voltage battery assembly through the screen and / or indicator lights.

[0043] It should be noted that the specific process of "CPU detecting the voltage of the high-voltage battery component" is prior art in this field, and therefore will not be described in detail here.

[0044] The above is a description of the high-voltage battery assembly. Some embodiments of this application also disclose an electronic device for identifying the battery's charging state. Please refer to... Figure 1 Electronic device A is powered by a high-voltage battery pack B with a full-charge voltage greater than a preset voltage threshold, including a control unit and an action execution component;

[0045] The control unit is configured to receive a preset voltage signal and output a first drive signal only when the preset voltage signal sent by the high-voltage battery component B is received; wherein, the preset voltage signal is obtained by converting the charging voltage applied by the high-voltage battery component B to the external power supply, so as to indicate that the high-voltage battery component B is currently in a charging state; the control unit includes a CPU;

[0046] The action execution component is driven by the first drive signal to execute the first action.

[0047] It should be noted that those skilled in the art can determine the first driving signal (such as high level or low level) according to actual needs. The specific type of the first driving signal and the specific process of "outputting the first driving signal only when the preset voltage signal sent by the high-voltage battery component B" are prior art in this field, and therefore will not be described in detail here.

[0048] In some embodiments, the control unit further includes a level conversion circuit 300, which has a control terminal and an output terminal. The control terminal of the level conversion circuit 300 is electrically connected to the high-voltage battery assembly B, and the output terminal is electrically connected to the CPU. The level conversion circuit 300 is normally maintained in a high state. In the high state, the level conversion circuit 300 outputs a high-level signal through its output terminal and sends it to the CPU. When the control terminal of the level conversion circuit 300 receives a preset voltage signal, it exits its high state and outputs a low-level signal through its output terminal and sends it to the CPU. If the CPU receives the low level (i.e., the aforementioned low-level signal), the CPU determines that the high-voltage battery assembly B is currently in a charging state; if the CPU does not receive the low level, the CPU determines that the high-voltage battery assembly B is not currently in a charging state.

[0049] In some embodiments, the control unit (such as a CPU) can directly receive the preset voltage signal (such as a 5V voltage signal) and determine whether the high-voltage battery assembly is currently charging by detecting whether the preset voltage signal is received.

[0050] In some embodiments, if the control unit (such as the CPU) cannot directly receive the preset voltage signal, the preset voltage signal can be converted into a low-level signal using other level conversion circuits (such as other commonly used voltage divider circuits). Since voltage divider circuits are prior art in this field, they will not be described in detail here.

[0051] In some embodiments, the preset voltage signal (such as a 5V voltage signal) can be converted into a low-level signal by a level conversion circuit, and then the control unit determines whether the preset voltage signal has been received by detecting whether a low-level signal has been received.

[0052] In some embodiments, the level shifting circuit includes a pull-up resistor; one end (i.e., the output terminal) of the pull-up resistor is electrically connected to a GPIO pin of the CPU, and the other end of the pull-up resistor is used to be electrically connected to the power supply voltage connected to the electronic device. The level shifting circuit also includes an NMOS transistor; wherein the drain of the NMOS transistor is electrically connected to a GPIO pin of the CPU, the source of the NMOS transistor is grounded, and the gate (i.e., the control terminal) of the NMOS transistor is used to receive the preset voltage signal.

[0053] It should be noted that the "power supply voltage connected to the electronic device" and the "charging voltage applied by the external power source" are usually different. For example, the power supply voltage connected to the electronic device (such as a mobile phone) is 3.3V, while the charging voltage applied by the external power source is 8V.

[0054] Since the GPIO pin is connected to the power supply voltage via a pull-up resistor, its level is high by default (if the preset voltage signal is not received). When the gate of the NMOS transistor receives the preset voltage signal, the NMOS transistor turns on, and the original high level on the CPU's GPIO pin is pulled low. By using the interrupt-triggered GPIO detection method described above, the overhead of the CPU continuously detecting the preset voltage signal can be reduced.

[0055] In some embodiments, both the level conversion circuit and the CPU are located on the motherboard.

[0056] In some embodiments, the action execution component further includes a display screen; the display screen is electrically connected to the CPU; when the CPU determines that the high-voltage battery assembly is currently in a charging state, the CPU sends charging status information to the display screen; the display screen is used to display the charging status information to indicate that the high-voltage battery assembly is currently in a charging state; when the CPU determines that the high-voltage battery assembly is not currently in a charging state, the display screen does not display the charging status information.

[0057] In some embodiments, the action execution component further includes an indicator light; the indicator light is electrically connected to the CPU; when the CPU determines that the high-voltage battery assembly is currently in a charging state, the CPU can enable the indicator light to be in a working state to indicate that the high-voltage battery assembly is currently in a charging state; when the CPU determines that the high-voltage battery assembly is currently not in a charging state, the CPU can enable the indicator light to be in a closed state to indicate that the high-voltage battery assembly is currently not in a charging state.

[0058] It is understood that "the action execution component is driven by the first drive signal to execute the first action" includes the display screen showing the above-mentioned charging status information, and / or the indicator light being in the working state / off state.

[0059] It should be noted that the specific process of "the action execution component being driven by the first drive signal to execute the first action" is existing technology in this field, and therefore will not be described in detail here.

[0060] As can be seen, in some embodiments, the level conversion circuit of the electronic device of this application generates a high level when it does not receive a preset voltage signal (such as 5V) sent by the high-voltage battery component, and sends the high level to the CPU of the electronic device; when and only when it receives the preset voltage signal sent by the high-voltage battery component, it uses the preset voltage signal to convert the high level to a low level and sends the low level to the CPU of the electronic device; and the CPU of the electronic device can determine whether the high-voltage battery component is currently in a charging state based on whether it receives the low level. For example, if the CPU of the electronic device detects the preset voltage signal (such as 5V), it indicates that the high-voltage battery component is in a charging state, and the electronic device can then indicate that the high-voltage battery component is currently in a charging state through the screen and / or indicator lights. When the high-voltage battery component is fully charged, the CPU of the electronic device detects that the voltage of the high-voltage battery component has reached its maximum value, and can then change the charging display status of the high-voltage battery component through the screen and / or indicator lights.

[0061] Please refer to Figure 1When an external power source applies a charging voltage to the cells of the high-voltage battery assembly B through the charging pin 100, a preset voltage generation module 200, electrically connected to the charging pin 100, generates a preset voltage signal (e.g., 5V). This preset voltage generation module 200 sends the preset voltage signal to the motherboard of the electronic device through the connection port between the high-voltage battery assembly and the electronic device. When the CPU on the motherboard detects this preset voltage signal, it displays that the high-voltage battery assembly is currently charging via the display screen 400 or the indicator light 500. When the external power source is removed, the preset voltage generation module 200 does not generate a preset voltage signal. In this case, the CPU of the electronic device cannot detect the preset voltage signal, and thus indicates via the display screen 400 or the indicator light 500 that the high-voltage battery assembly B is not currently charging.

[0062] The above is a description of an electronic device used to identify the battery charging state. A motherboard is also disclosed in some embodiments of this application. Please refer to... Figure 1 The motherboard C can be installed in electronic device A, which is powered by a high-voltage battery pack B with a full charge voltage greater than a preset voltage threshold.

[0063] The motherboard C includes:

[0064] The control unit is configured to receive a preset voltage signal and output a first drive signal only when the preset voltage signal sent by the high-voltage battery component B is received; wherein, the preset voltage signal is obtained by converting the charging voltage applied by the high-voltage battery component B to the external power supply, so as to indicate that the high-voltage battery component B is currently in a charging state; the control unit includes a CPU.

[0065] In some embodiments, the control unit further includes a level conversion circuit 300, which has a control terminal and an output terminal. The control terminal of the level conversion circuit 300 is electrically connected to the high-voltage battery assembly B, and the output terminal is electrically connected to the CPU. The level conversion circuit 300 is normally maintained in a high state. In the high state, the level conversion circuit 300 outputs a high-level signal through its output terminal and sends it to the CPU. When the control terminal of the level conversion circuit 300 receives a preset voltage signal, it exits its high state and outputs a low-level signal through its output terminal and sends it to the CPU. If the CPU receives the low level signal, the CPU determines that the high-voltage battery assembly B is currently in a charging state; if the CPU does not receive the low level signal, the CPU determines that the high-voltage battery assembly B is not currently in a charging state.

[0066] In some embodiments, the motherboard also integrates a power management integrated circuit (PMIC).

[0067] In some embodiments, the level conversion circuit includes a pull-up resistor and an NMOS transistor; wherein one end of the pull-up resistor is electrically connected to a GPIO pin of the CPU, and the other end of the pull-up resistor is used to be electrically connected to a power supply voltage connected to the electronic device; the drain of the NMOS transistor is electrically connected to a GPIO pin of the CPU, the source of the NMOS transistor is grounded, and the gate of the NMOS transistor is used to receive the preset voltage signal.

[0068] It should be noted that the power supply voltage and the charging voltage mentioned above are usually different. For example, the power supply voltage connected to the electronic device (such as a mobile phone) is 3.3V, while the charging voltage applied by the external power source is 8V.

[0069] Since the GPIO pin is connected to the power supply voltage via a pull-up resistor, the GPIO pin is at a high level by default (if the preset voltage signal is not received). When the gate of the NMOS transistor receives the preset voltage signal, the NMOS transistor turns on, and the original high level on the CPU's GPIO pin is pulled low.

[0070] In some embodiments, the CPU is also electrically connected to a display screen; wherein, when the CPU determines that the high-voltage battery assembly is currently in a charging state, the CPU sends charging status information to the display screen; the display screen is used to display the charging status information to indicate that the high-voltage battery assembly is currently in a charging state; when the CPU determines that the high-voltage battery assembly is not currently in a charging state, the display screen does not display the charging status information.

[0071] In some embodiments, the CPU is also electrically connected to an indicator light; wherein, when the CPU determines that the high-voltage battery assembly is currently in a charging state, the CPU can enable the indicator light to be in an active state to indicate that the high-voltage battery assembly is currently in a charging state; when the CPU determines that the high-voltage battery assembly is currently not in a charging state, the CPU can enable the indicator light to be in an off state to indicate that the high-voltage battery assembly is currently not in a charging state.

[0072] As can be seen, in some embodiments, the level conversion circuit on the motherboard of this application generates a high level when it does not receive a preset voltage signal (such as 5V) sent by the high-voltage battery component, and sends the high level to the CPU of the motherboard; when and only when it receives the preset voltage signal sent by the high-voltage battery component, it uses the preset voltage signal to convert the high level to a low level and sends the low level to the CPU of the motherboard; and the CPU of the motherboard can determine whether the high-voltage battery component is currently in a charging state based on whether it receives the low level. For example, if the CPU on the motherboard detects the preset voltage signal (such as 5V), it indicates that the high-voltage battery component is in a charging state, and the CPU on the motherboard can then indicate that the high-voltage battery component is currently in a charging state through the screen and / or indicator lights. When the high-voltage battery component is fully charged, the CPU on the motherboard detects that the voltage of the high-voltage battery component has reached its maximum value, and can then change the charging display status of the high-voltage battery component through the screen and / or indicator lights.

However, those skilled in the art will recognize that changes and modifications can be made to the exemplary embodiments without departing from the scope of this document. For example, various operational steps and components for performing operational steps can be implemented in different ways depending on the specific application or considering any number of cost functions associated with the operation of the system (e.g., one or more steps can be deleted, modified, or combined with other steps).

[0074] In the above embodiments, implementation can be achieved, in whole or in part, by software, hardware, firmware, or any combination thereof. Furthermore, as those skilled in the art will understand, the principles herein can be reflected in a computer program product on a computer-readable storage medium pre-loaded with computer-readable program code.
