FIG. 1 is a block diagram of an electronic device according to an embodiment of the invention. Referring to fig. 1, the electronic device 100 may apply the transmission specification of USB Type-C. In the present embodiment, the electronic device 100 may include a power adapter 110 and a charging control device 120. The power adapter 110 is coupled to the charging control device 120. The power adapter 110 may also be coupled to an external device (not shown) such that the external device charges the charge control device 120 through the power adapter 110. The external device may be, for example, a mobile power supply or a power outlet. The charging control device 120 may be a power device such as a mobile phone, a tablet computer, a notebook computer, and a desktop computer.
In the present embodiment, the power adapter 110 may include a first controller 111 and a sensor 112. The sensor 112 is coupled to the first controller 111. The sensor 112 may be, for example, a Giant Magnetoresistive (GMR) sensor, a gravity sensor (G-sensor), and a contact sensor (Proximity seneor). The first controller 111 may be, for example, a Power Delivery (PD) controller.
In the present embodiment, the charging control device 120 may include a second controller 121. The second controller 121 is coupled to the first controller 111 and the sensor 112. The second controller 121 may be, for example, a power supply controller. In this embodiment, the power supply controller (i.e., controllers 111, 121) may comprise a signal converter, a field programmable gate array (Field Programmable GATE ARRAY, FPGA), a central processing unit (Central Processing Unit, CPU), or other general purpose or special purpose Microprocessor (Microprocessor), digital signal processor (Digital SignalProcessor, DSP), programmable controller, application specific integrated circuit (Application SpecificIntegrated Circuits, ASIC), programmable logic device (Programmable Logic Device, PLD), or other similar device or combination of devices that can be loaded with and execute computer program related firmware or software to perform the processing, computing, and execution functions.
Fig. 2 is a flowchart illustrating an operation method of the electronic device according to an embodiment of the invention. Referring to fig. 1 and 2, the electronic device 100 may execute steps S210 to S240. The order of steps S210 to S240 is only illustrative, but not limited thereto. In this embodiment, steps S210 to S240 may be applied to the following exemplary cases.
In the present embodiment, the power adapter 110 may be abutted against the working surface in various manners, and charge the charge control device 120 in this scenario. Taking the power adapter 110 of a column as an example, a user can lie any side of the power adapter 110 on a working surface to have a corresponding placement state.
In step S210, the sensor 112 senses the placement state of the power adapter 110 to generate a sensing signal S1-1. In the present embodiment, the sensing signal S1-1 may be, for example, a signal indicating the placement state of the power adapter 110. The sense signal S1-1 may include coordinate data (e.g., the "coordinates" in table (1)) of the power adapter 110.
In step S220, the first controller 111 generates event information S1-2 according to the sensing signal. In the present embodiment, the event information S1-2 may be, for example, information indicating a status event of the power adapter 110. The event information S1-2 may include information that the power adapter 110 maintains a certain placement state, and that the placement state of the power adapter 110 changes.
In step S230, the second controller 121 selects a first power supply setting information (e.g., the information D1) of the plurality of power supply setting information D1-DN according to the sensing signal S1-1 and the event information S1-2 to generate the control signal S2, wherein N is a positive integer greater than 1. In this embodiment, the power setting information D1-DN may be, for example, a plurality of power profiles (PD profiles) indicating different power settings under the transmission specification of USB Type-C. The power supply settings may include settings for supply voltage, supply current, and supply power.
In step S240, the first controller 111 causes the power adapter 110 to perform a power supply operation according to the first power supply setting information D1 according to the control signal S2. That is, the second controller 121 can select different power setting information D1 to DN according to various placement states of the power adapter 110. The power adapter 110 may perform a power supply operation based on a corresponding one of the power supply setting information D1 to DN.
It should be noted that, since various placement states of the power adapter 110 may correspond to different power supply setting information D1 to DN, a user can set the placement state of the power adapter 110, and the charging control device 120 selects the power supply setting information (e.g., the first power supply setting information D1) corresponding to the current placement state. In this way, the power adapter 110 can provide the corresponding power based on the selected power setting information D1, thereby satisfying various charging scenarios to increase the service flexibility of the electronic device 100 and simultaneously increase the service life of the electronic device 100.
Fig. 3 is a schematic diagram illustrating an operation of an electronic device according to an embodiment of the invention. Referring to fig. 3, the electronic device 300 may include a power adapter 310 and a charge control device 320. The power adapter 310 may include a first controller 311, a sensor 312, a switching circuit 313, and an information prompter 314. The first controller 311 is coupled to the sensor 312, the switch circuit 313 and the information indicator 314. The charge control device 320 may include a second controller 321. The power adapter 310, the charging control device 320, the first controller 311, the sensor 312, and the second controller 321 may refer to the relevant description of the electronic device 100 and so on.
In the present embodiment, the switch circuit 313 is coupled between paths of the power supply channel pin of the first controller 311 for receiving the power supply voltage. The power supply channel pin of the first controller 311 may be, for example, the pin VBUS to transmit power. The supply voltage may be, for example, a voltage at a power supply (Source). In the present embodiment, the switch circuit 313 is further coupled to the second controller 321. The switch circuit 313 may be controlled by a control signal (e.g., the control signal S2 shown in fig. 1) from the second controller 321, so that the switch circuit 313 performs a switching operation according to the control signal.
In this embodiment, the information prompter 314 is coupled to the first controller 311. The information prompter 314 may be controlled by a signal from the first controller 311 for performing a power supply operation, so that the information prompter 314 provides a prompt message corresponding to the power supply setting information (e.g. the first power supply setting information D1) performed by the power adapter 310.
In this embodiment, the information indicator 314 may be disposed on any side of the power adapter 310. The information indicator 314 may be, for example, a display that provides a display function, including a Liquid Crystal Display (LCD), a light-Emitting Diode (LED), an organic light-Emitting Diode (OLED), and the like. In the present embodiment, the prompt information may include various colored lights corresponding to different placement states of the power adapter 310, various carbon emission information, or a combination of the foregoing.
It should be noted that the user can clearly know the current charging mode through the prompt message (for example, a color light of a certain color) output by the message prompt 314. The charging mode may be, for example, a mode in which the power adapter 310 performs a power supply operation to the power adapter 310 based on the first power supply setting information D1.
In the present embodiment, the second controller 321 is further coupled to a memory (not shown). The memory may store a plurality of power setting information D1-DN, where N is illustrated as 4. That is, the second controller 321 may access the first to fourth power setting information D1 (denoted as "PD profile 1") to D4 (denoted as "PD profile 4") in the memory. In this embodiment, the memory may be, for example, an external memory or a memory provided in the charging control device 320. The memory may be, for example, a dynamic Random access memory (Dynamic Random Access Memory, DRAM), a Flash memory (Flash memory), or a Non-Volatile Random access memory (Non-Volatile Random AccessMemory, NVRAM), or the like.
In the present embodiment, the power setting information D1 to D4 may include a plurality of power supplies corresponding to different placement states of the power adapter 310. These power supplies are within an extended power range (ExtendedPower Range, EPR). The correspondence between the placement state and the EPR specification is shown in the following table (1).
Table (1):
referring to fig. 4 together, fig. 4 is a schematic structural diagram of the power adapter according to the embodiment of fig. 3. In this embodiment, the power adapter 310 may include four sides. The side surfaces are respectively laid on the working surface in the corresponding placing directions SD 1-SD 4 to have respective placing states.
For example, the first power setting information D1 corresponds to a first placement state. The first placement state may be, for example, a state when the power adapter 310 is lying across the work surface in the placement direction SD 1. The first pose state has coordinates denoted (1, 0). The first power supply setting information D1 includes a first power supply. The first power supply power instructs the power adapter 310 to perform a power supply operation with a charging voltage of 36V and a charging current of 5A. The first power supply setting information D1 further includes first prompt information. The first hint information instructs the information prompter 314 to emit red light. The second power supply setting information D2, the third power supply setting information D3, and the fourth power supply setting information D4 can be analogized with reference to the description related to the first power supply setting information D1.
It should be noted that since the fourth power supply power of the fourth power supply setting information D4 may be, for example, the lowest power supply power satisfying the EPR specification, the fourth power supply setting information D4 may be defined as an eco power supply mode. The user can select the power setting information D4 by setting the placement state of the power adapter 310 in response to environmental protection. In the present embodiment, the fourth power supply setting information D4 defined as the environment-friendly power supply mode may be designed or modified to have a corresponding power supply power in cooperation with the battery configuration of the charging control device 320.
In the present embodiment, the electronic device 300 may execute the modules S410-S432 to illustrate how to switch to different power settings for charging. It is assumed that the current power adapter 310 has a first put state and performs a power supply operation with the first power supply setting information D1. Assume that the power adapter 310 is flipped from the first to the second state of placement.
In block S410, the power adapter 310 performs a power supply operation and is flipped so that the placement state of the power adapter 310 is changed. The sensor 312 senses the present placement state of the power adapter 310 to generate a sensing signal (e.g., the sensing signal S1-1 shown in FIG. 1). The sensor 312 transmits the sensing signal to the first controller 311 and the second controller 321 through transmission lines, respectively. In this embodiment, the sensing signal includes coordinate data of the power adapter 310. The coordinate data may be, for example, the "coordinates" (i.e., (0, 1, 0)) in table (1) corresponding to the second pose state.
Continuing the above description, the first controller 311 receives the sensing signal and generates event information (e.g., event information S1-2 shown in fig. 1) according to the sensing signal. The first controller 311 transmits event information to the second controller 321 through a set of configuration channels (Configuration Channel, CC). In the present embodiment, the event information indicates that the placement state of the power adapter 310 is changed.
At block S420, the second controller 321 receives the sensing signal and the event information, and switches (e.g., turns off) the switching circuit 313 according to the event information. That is, during the charging process, when the placement state of the power adapter 310 is changed, the second controller 321 learns the aforementioned changing scenario according to the event information, and cuts off the path between the power supply voltage and the power supply channel pins (for example, the pins VBUS) in the power adapter 310 accordingly.
In the present embodiment, after the switch circuit 313 is turned off, the second controller 321 switches the plurality of power setting information D1 to D4 according to the sensing signal and the event information to select the second power setting information D2 corresponding to the current placement state (i.e., the second placement state) of the power adapter 310.
In detail, in block S431, the second controller 321 analyzes the sensing signal according to the event information to interpret the coordinate data of the power adapter 310. That is, the second controller 321 reads the sensor 312 through the transmission line to acquire the coordinate data of the power adapter 310 when the second controller 321 receives the event information.
In block S432, the second controller 321 designates and reads the power supply setting information D1 to D4 in the memory according to the sensing signal. The second controller 321 selects the second power supply setting information D2 to switch the first power supply setting information D1 to the second power supply setting information D2 according to the interpreted coordinate data, i.e., the coordinates (0, 1, 0) of the second placement state.
Following the above description, when the switching circuit 313 is turned off, the second controller 321 generates a control signal according to the switched (or selected) second power setting information D2. The second controller 321 transmits control signals to the first controller 311 through a set of configuration channels. In addition, the second controller 321 switches (e.g., turns on) the switching circuit 313 to enable the power adapter 310 to re-receive the power supply voltage to enable the power supply operation.
That is, when the second controller 321 completes the switching of the power supply setting information D1, D2, the second controller 321 informs the first controller 311 of the updated second power supply setting information D2, and the second controller 321 releases the power outage between the power adapter 310 and the power supply voltage. Accordingly, the power adapter 310 can re-complete the power communication based on the second power setting information D2 to continue the power operation.
In this embodiment, in order to prevent the placement state of the power adapter 310 from being changed carelessly, for example, when the user trips over the power adapter 310, the second controller 321 stops generating the control signal during a preset period in which event information is received. That is, when the second controller 321 receives the event information, the second controller 321 waits for a period of time to make the placement state of the power adapter 310 appear stable. After this period of time, the second controller 321 then generates a control signal according to the current event information. Therefore, the second controller 321 does not generate a control signal according to the current event information during this period of time (i.e., a preset period).
In this embodiment, in order to protect the service life of the charging control device 320, when the remaining power of the charging control device 320 is too low, the second controller 321 does not switch the power supply setting information D1, D2 according to the sensing signal and the event information. In detail, the second controller 321 stops generating the control signal according to the remaining power of the charge control device 320 being less than the threshold (for example, the power is 0%).
In summary, in the electronic device and the operating method thereof according to the embodiments of the present invention, the corresponding power supply setting information is selected by switching the placement state of the power adapter, so that the user can adjust the power supply setting of the power adapter by himself, for example, the setting that the power supply voltage of the power adapter approaches the voltage of the charging control device. Therefore, the electronic device can improve the efficiency of charging the charging control device and reduce the power consumption of the charging control device, thereby achieving the energy-saving effect. In addition, the power adapter can provide corresponding power supply power based on the selected power supply setting information, so that the service flexibility and the service life of the electronic device are improved.
It should be noted that the above embodiments are merely for illustrating the technical solution of the present invention and not for limiting the same, and although the detailed description of the present invention has been described with reference to the above embodiments, it should be understood by those skilled in the art that modifications may be made to the technical solution described in the above embodiments or equivalents may be substituted for some or all of the technical features thereof, and these modifications or substitutions do not deviate the essence of the corresponding technical solution from the scope of the technical solution of the embodiments of the present invention.
