In order to solve the technical problems of the related art, the embodiment of the application provides electronic equipment, which comprises a control module, an input interface, a plurality of output interfaces, a first power chip and a second power chip, wherein the second power chip corresponds to the output interfaces one by one, the first power chip can acquire input electric parameters matched with electric power output parameters of the power supply equipment through the input interface when the power supply equipment is connected with the input interface, then the control module determines power supply parameters based on the input electric parameters and the power receiving parameters of the power receiving equipment connected with the output interface, and finally the second power chip provides electric energy of the power supply equipment to the power receiving equipment through a power supply circuit based on the power supply parameters. In this way, the control module can not only reduce the damage risk of the power receiving device caused by overvoltage, overcurrent and overpower charging, but also dynamically adapt to the optimal power supply efficiency interval of the power receiving device through the input electrical parameter adapted to the power output parameter of the power supply device and the power receiving parameter of the power receiving device, thereby improving the charging efficiency of the power receiving device. In addition, each output interface corresponds to a second power supply chip, so that independent regulation and control and parallel power supply of the multiple output interfaces are realized, the risk of interference or power distribution conflict caused by sharing a power supply channel by multiple devices is reduced, and the charging safety of the powered device is improved.

In the following, a detailed description of the technical solution of the present application is provided with, as shown in fig. 1, a control module 101, an input interface 102, a plurality of output interfaces 103 (5 output interfaces are shown in fig. 1), a first power chip 104, and second power chips 105 (5 second power chips are shown in fig. 1) corresponding to the output interfaces 103 one by one;

The input interface 102 is connected with the control module 101 through a first power chip 104, the plurality of output interfaces 103 are respectively connected with the control module 101 through a second power chip 105 corresponding to each other, the input interface 102 is connected with the plurality of output interfaces 103 to form at least two power supply lines, wherein,

A first power chip 104, configured to obtain an input electrical parameter through the input interface 102, where the input electrical parameter is adapted to an electrical output parameter of a power supply device (not shown) connected to the input interface 102;

A control module 101, configured to determine a power supply parameter based on an input electrical parameter and a power receiving parameter of a power receiving device (not shown in the figure) connected to the output interface, and transmit the power supply parameter to the second power supply chip 105;

The second power supply chip 105 is configured to supply, via a power supply line, electric power of the power supply apparatus to the power receiving apparatus based on the power supply parameter.

In the embodiment of the application, the input interface is used for connecting with power supply equipment. Illustratively, the input interface 102 may be a universal serial bus Type-C (Universal Serial Bus Type-C INTERFACE, USB Type-C) female port, which is a power input port of an electronic device. The power supply device may include an adapter connectable with a power source to provide power to the electronic device and a power source. The output interface 103 is used for connecting a powered device, and the electronic device can transmit the electric energy of the power supply device to the powered device through the output interface 103 so as to charge the powered device. Illustratively, the output interface 103 may be a USB Type-C male plug, which is a power outlet of an electronic device.

In an embodiment of the present application, the first Power chip 104 may be a Power chip having a function of identifying an electrical parameter of a device connected to the input interface 102, and the first Power chip 104 may be a Sink USB Power DELIVERY INTEGRATED Circuit (Sink PD IC) as an example. Where the powered device is connected to the input interface 102 through an adapter of the electronic device, the first power supply chip 104 may transmit an electrical parameter acquisition request to the adapter, and the adapter may transmit a plurality of electrical parameters to the first power supply chip 104 in response to the electrical parameter acquisition request, where the first power supply chip 104 may be able to select an input electrical parameter that matches itself among the plurality of electrical parameters.

It will be appreciated that the first power chip 104 supports a plurality of electrical parameters, and after acquiring the plurality of electrical parameters transmitted by the adapter, an input electrical parameter matching itself may be selected from the plurality of electrical parameters, and then the adapter may deliver electrical energy to the electronic device based on the input electrical parameter. Illustratively, the first power chip 104 supports two different voltage class specifications, PD3.0 and PD3.1, and the first power chip 104 supports power classes PD3.0 45W,PD3.0 65W,PD3.0 100W,PD3.0 140W,PD3.1 140W,PD3.1 180W, respectively.

In the embodiment of the present application, when the first power chip 104 obtains the input electrical parameter, the input electrical parameter may be transmitted to the control module 101. In the case where the power receiving apparatus is connected to the output interface 103 of the electronic apparatus, the control module 101 can acquire the power receiving parameter of the power receiving apparatus through the output interface 103, and then the control module 101 determines the power supply parameter based on the input electrical parameter and the power receiving parameter of the power receiving apparatus. The control module 101 may send a power reception parameter acquisition request to a controller of the power reception device, and the controller of the power reception device sends the power reception parameter of the power reception device to the control module 101 in response to the power reception parameter acquisition request. Illustratively, the control module 101 of the electronic device may be a microcontroller (Microcontroller Unit, MCU) and the controller of the powered device may be an embedded controller (Embedded Controller, EC).

In some embodiments, when the powered device is in a power-off state, the controller of the powered device is in a sleep state, and when the powered device is connected to the output interface 103, the electronic device transmits an electrical signal to the powered device through the output interface 103, and the electrical signal can wake up the controller of the powered device, so as to complete interaction of power receiving parameters of the powered device. Thus, the power receiving parameter of the power receiving apparatus can be acquired even when the power receiving apparatus is in the power-off state.

In the embodiment of the present application, when the control module 101 obtains the input electrical parameter and the power receiving parameter of the power receiving device, the input electrical parameter and the power receiving parameter may be compared to obtain a comparison result of the input electrical parameter and the power receiving parameter, and then, a power supply parameter for transmitting electric energy to the power receiving device is determined based on the comparison result of the input electrical parameter and the power receiving parameter, and the power supply parameter is sent to the second power supply chip 105. The power supply parameter is used for representing a power supply mode for supplying power to the power receiving equipment. The second Power chip 105 may be, for example, a USB Power DELIVERY INTEGRATED Circuit (PD IC).

For example, if the input electrical parameter is equal to the power receiving parameter, it may indicate that the power supply device outputs electric energy to the electronic device through the adapter, and the electric energy receiving capability of the power receiving device is matched, so that the power receiving parameter is the input electrical parameter, that is, the electronic device adopts a direct power supply mode to supply power to the power receiving device; if the input electrical parameter is smaller than the power receiving parameter, the power supply equipment can not completely meet the power receiving requirement of the power receiving equipment, and the output power needs to be subjected to boosting treatment, so that the power receiving parameter is the boosted input electrical parameter, namely the electronic equipment supplies power to the power receiving equipment in a boosting power supply mode.

In some embodiments, after determining the power supply parameter, the control module 101 needs to determine a target power supply chip among the plurality of second power supply chips 105, where the target power supply chip refers to the second power supply chip 105 corresponding to the output interface 103 to which the powered device is connected. That is, the target power supply chip may be at least one second power supply chip 105 of the plurality of second power supply chips 105, and when only one output interface 103 is connected to a powered device, the second power supply chip 105 corresponding to the output interface 103 is the target power supply chip, and when all the output interfaces 103 are connected to powered devices, all the second power supply chips 105 are target power supply chips.

In the embodiment of the present application, the control module 101 may detect the pin voltage of each output interface 103, and if the target pin voltage within the preset voltage range exists in each pin voltage, it is determined that the output interface 103 corresponding to the target pin voltage is connected to the powered device, and then the second power chip 105 corresponding to the output interface 103 is the target power chip. Illustratively, where output interface 103 is a USB Type-C male, the pin voltage is a CC pin voltage.

In the embodiment of the present application, when the power supply device is connected to the input interface 102, the first power chip 104 can recognize the input electrical parameters of the adapter through interaction with the adapter. Thus, accurate acquisition of the adaptive power by the electronic equipment can be realized, and meanwhile, the power supply compatibility and the safety and high efficiency of power transmission are ensured. The control module 101 then compares the input electrical parameter with the power receiving parameter, determines a power supply parameter for transmitting electric power to the power receiving apparatus based on the comparison result of the two, and transmits the power supply parameter to the second power supply chip 105. In this way, the power supply mode matched with the power receiving capability of the power receiving equipment can be adopted to supply power to the power receiving equipment, so that the power supply efficiency of the power receiving equipment is improved.

In some embodiments, the input electrical parameter comprises an input current, the power receiving parameter comprises a power receiving voltage, and the control module 101 is configured to determine an output current based on the input current and the number of output interfaces 103, determine the power receiving voltage as an output voltage, and determine the output voltage and the output current as supply parameters.

Here, the input current refers to a current value input from an external power supply device (such as a charger or a power adapter) into the first power chip 104. The input current parameter reflects the actual power supply capacity of the input power source. The power receiving voltage refers to the maximum charging voltage that the power receiving apparatus can accept. For example, when the power receiving apparatus is a notebook computer, the power receiving voltage may be 20V.

In the embodiment of the present application, the control module 101 may allocate an output current to each output interface 103 according to the number of output interfaces 103 and a current required by the electronic device. Illustratively, in the case of an input current of 2.25A, the output current of each output interface 103 may be 0.4A, the current required by the electronic device is 0.25A, in the case of an input current of 3.25A, the output current of each output interface 103 may be 0.6A, the current required by the electronic device is 0.25A, and in the case of an input current of 5A, the output current of each output interface 103 may be 0.95A, the current required by the electronic device is 0.25A.

In the embodiment of the present application, the control module 101 uses the maximum charging voltage that the powered device can accept as the output voltage of the electronic device. It is understood that the voltage of the electric energy output by the power supply device to the electronic device through the adapter may be different from the power receiving voltage of the power receiving device, if the voltage of the electric energy output by the power supply device to the electronic device through the adapter is directly taken as the power receiving voltage of the power receiving device, the risk of damage to the power receiving device caused by over-voltage charging may occur, or the charging efficiency of the power receiving device may be reduced due to the condition that the power receiving device does not reach the optimal power supply efficiency interval of the power receiving device, so that the maximum charging voltage acceptable by the power receiving device needs to be taken as the output voltage of the electronic device.

In some embodiments, if the voltage of the electric energy output by the power supply device to the electronic device through the adapter is greater than the power receiving voltage of the power receiving device, the step-down processing needs to be performed on the electric energy output by the power supply device to the electronic device through the adapter, if the voltage of the electric energy output by the power supply device to the electronic device through the adapter is less than the power receiving voltage of the power receiving device, the step-up processing needs to be performed on the electric energy output by the power supply device to the electronic device through the adapter, and if the voltage of the electric energy output by the power supply device to the electronic device through the adapter is equal to the power receiving voltage of the power receiving device, no processing needs to be performed on the output electric energy, and the electric energy is directly provided to the power receiving device.

In the embodiment of the application, the output current is reasonably distributed through the quantity of the input current and the output interfaces, so that the problems of overload or current waste can be effectively prevented. Meanwhile, the power receiving voltage is used as the output voltage, so that the damage risk of the power receiving equipment caused by over-voltage charging can be reduced, or the problem that the charging efficiency of the power receiving equipment is reduced due to the fact that the optimal power supply efficiency interval of the power receiving equipment is not reached is solved.

In some embodiments, the input electrical parameters further include an input voltage, as shown in fig. 2, the electronic device further includes a plurality of voltage reduction modules 201 corresponding to the output interfaces 103 one by one, and the plurality of voltage reduction modules 201 are respectively disposed on the corresponding power supply lines, where the second power supply chip 105 is configured to control the voltage reduction module 201 corresponding to the second power supply chip 105 to perform voltage reduction processing on the electric energy of the power supply device if the output voltage of the power supply parameter is less than the input voltage, and provide the reduced electric energy to the power receiving device based on the power supply parameter through the power supply line.

Here, the input voltage refers to an output voltage of an adapter of the electronic device, and the input voltage is an important basis for determining whether voltage conversion is needed in the following. For example, under the PD3.1 specification, the input voltage may need to be reduced to 20V to meet the input requirement of some powered devices, and under the PD3.0 specification, the input voltage may not need to be reduced to directly provide the power of the power supply device to the powered devices when the input voltage is 20V.

As shown in fig. 2, a step-down module 201 is disposed on each power supply line for connecting the input interface 102 and the output interface 130, and if the output voltage of the power supply parameter sent by the control module 101 received by the second power supply chip 105 is smaller than the input voltage of the power receiving device, the corresponding step-down module 201 is controlled to step down the power of the power supply device. The control process of the voltage step-down module 201 by the second power chip 105 may refer to controlling the current of the power supply device to pass through the voltage step-down module 201 to step-down the voltage of the electric energy of the power supply device. For example, when the buck module 201 is connected in parallel with a switching module, the switching module may be controlled to be turned off. In some embodiments, the control process of the voltage reducing module 201 by the second power supply chip 105 may refer to controlling the operating state of the voltage reducing module 201, and when the voltage reducing module 201 is required to perform voltage reducing processing on the electric energy of the power supply device, the voltage reducing module 201 may be controlled to be in the operating state. Illustratively, the buck module 201 may be a direct current-direct current converter (Direct Current to Direct Current Converter, DCDC).

In the embodiment of the present application, each output interface is equipped with an independent buck module 201 to support independent power supply control during parallel charging of multiple devices. The use of the design of the independent step-down module 201 can ensure that each connected device can obtain a voltage and current that are stable and meet the requirements of the powered device, without being affected by other devices. For example, when one output interface requires 20V power, the corresponding buck module 201 will convert the input 28V voltage to 20V, while other output interfaces that are not enabled for buck may remain in pass-through mode. Thus, integrating the buck module 201 on each power supply line can increase the flexibility and stability of the system as a whole and enhance the fault isolation capability of the system. When an abnormality occurs in a certain step-down module 201, since each power supply line is independent of the other, normal operation of the entire electronic device is not affected.

In the embodiment of the present application, when the input voltage is higher than the required output voltage, the second power chip 105 may control the corresponding step-down module 201 to perform step-down processing, so that the output voltage meets the requirements of the powered device, and compatibility and safety are improved.

In some embodiments, as shown in fig. 3, the electronic device further includes a switch module 301 corresponding to the output interface 103 one by one, where the switch module 301 is connected in parallel with the respective voltage reduction module 201, and the second power supply chip 105 is configured to control the switch module 301 corresponding to the second power supply chip 105 to be closed if the output voltage of the power supply parameter is equal to the input voltage, and provide, through the power supply line, electric energy of the power supply device to the power receiving device through the power supply parameter.

In the embodiment of the present application, the switch module 301 and the buck module 201 are connected in parallel, that is, the switch module 301 and the buck module 201 are connected to the same power supply path respectively, but they do not affect each other. When the switch module 301 is in the closed state, the current can be directly transmitted to the output terminal through the switch module 301, and when the switch module 301 is in the open state, the current is processed by the step-down module 201. The parallel connection manner between the switch module 301 and the buck module 201 enables the system to be seamlessly switched between the direct power supply mode and the buck power supply mode, so that flexibility and efficiency of charging the powered device by the electronic device are improved.

In the embodiment of the present application, when the output voltage of the power supply parameter is equal to the input voltage, the second power supply chip 105 may send the first electrical signal to the switch module 301, so that the switch module 301 corresponding to the second power supply chip 105 is closed, and at this time, the current may be directly transmitted to the output end through the switch module 301, and the current is not processed by the step-down module 201, that is, the power receiving device is powered by adopting a through power supply mode. For example, under the PD3.1 specification, when the input voltage is 28V, if the power receiving voltage of the power receiving device is also 28V, the switch module 301 corresponding to the second power supply chip 105 may be controlled to be closed, and under the PD3.0 specification, when the input voltage is 20V, the power receiving voltage of the power receiving device is 20V, the switch module 301 corresponding to the second power supply chip 105 may be controlled to be closed.

In some embodiments, when the output voltage of the power supply parameter is greater than the input voltage, the second power supply chip 105 may send a second electrical signal to the switch module 301, so that the switch module 301 corresponding to the second power supply chip 105 is turned off, and at this time, the current is transmitted to the output terminal through the step-down module 201, that is, the power receiving device is powered by adopting a step-down power supply mode. For example, under the PD3.1 specification, when the input voltage is 28V, if the power receiving voltage of the power receiving device is 20V, the switch module 301 corresponding to the second power chip 105 may be controlled to be turned off, and the voltage is reduced to 20V by the voltage reducing module 201, so as to supply power to the power receiving device.

In some embodiments, the electronic device further includes a plurality of boost modules corresponding to the output interfaces one by one, the plurality of boost modules are respectively provided with corresponding power supply lines, and each of the buck modules 201 is further connected in series with a switch unit, and when the output voltage of the power supply parameter is smaller than the input voltage, the corresponding switch unit is controlled to be turned off, and the corresponding switch module 301 is controlled to be turned off, so that current flows through the boost modules, so that the voltage of the electric energy of the power supply device can be boosted by the boost modules. The boost module may be a direct current boost module, for example.

In the embodiment of the application, when the input voltage is higher than the required output voltage, the second power chip can control the corresponding voltage reducing module to reduce the voltage. Therefore, when the electronic device is connected with a plurality of powered devices, the second power chip can charge each powered device in different charging modes based on different voltages supported by different powered devices, for example, one power supply line charges the powered device in a straight-through mode, and the other power supply line charges the powered device in a step-down mode, so that the output voltage of each power supply line of the electronic device meets the requirements of each powered device, and compatibility and safety are improved.

In some embodiments, as shown in fig. 4, the electronic device further includes a display module 401, where the second power chip 105 is further configured to send an information acquisition request to a controller of the powered device, receive attribute information of the powered device sent by the controller in response to the information acquisition request, and transmit the attribute information of the powered device to the control module 101, where the attribute information includes power information of the powered device and/or identification information of the powered device, and the control module 101 is further configured to control the display module 401 to display the attribute information of the powered device.

Here, the identification information of the power receiving apparatus may be unique identification information of the power receiving apparatus, such as a serial number, a model number of the power receiving apparatus.

In the embodiment of the present application, when the output interface corresponding to the second power chip 105 is connected to the powered device, the second power chip 105 may communicate with the controller of the powered device through the output interface, that is, send an information acquisition request to the controller of the powered device. The second power chip 105 may send the attribute information of the power receiving device to the control module 101 after receiving the attribute information of the power receiving device, and the control module 101 may control the display module 401 to display the attribute information of the power receiving device or process the attribute information of the power receiving device, and then control the display module 401 to display the processed attribute information.

In some embodiments, when the powered device is in the dormant state, if the powered device is connected to the output interface of the electronic device, the electronic device transmits an electrical signal to the powered device through the output interface, so as to wake up the controller of the powered device in the dormant state, so that a communication link can be established with the powered device. The controller of the powered device may be an embedded controller (Embedded Controller, EC), for example.

In some embodiments, the power information of the powered device includes a design power of a battery of the powered device and a current power of the battery, at which time the control module 101 may determine a power percentage of the powered device based on the design power of the battery of the powered device and the current power of the battery, and then control the display module 401 to display the power percentage of the powered device. In other embodiments, the power information of the powered device further includes a remaining power (SOC), and the control module 101 does not need to process the information at this time, and controls the display module 401 to display the remaining power of the powered device.

In the embodiment of the present application, the display module 401 includes a plurality of display areas corresponding to the output interfaces one by one, and when the output interfaces are connected with the powered device, attribute information of the powered device is displayed in the display areas corresponding to the output interfaces. As shown in fig. 4, the number of output interfaces is 5, the number of display areas in the display module 401 is also 5, the output interfaces are in one-to-one correspondence, 3 output interfaces of the current 5 output interfaces are connected with powered devices, the electric quantity of the 3 powered devices is 5%, 75% and 100%, and two output interfaces are not connected with powered devices, so that the corresponding display area displays "N.C", that is, indicates that the corresponding output interfaces are not connected with powered devices.

In the embodiment of the application, through the communication between the second power chip 105 and the powered device controller, key information such as electric quantity and device identification can be obtained in real time, and the key information is displayed through the display module 401, so that a user can conveniently know the charging state of the powered device, and the man-machine interaction experience is enhanced.

In some embodiments, as shown in fig. 4 and fig. 5, the electronic device further includes a peripheral interface 402, where the peripheral interface 402 is connected to the control module 101, and the peripheral interface 402 is configured to transmit identification information of the powered device acquired by the information acquisition device to the control module 101, and the control module 101 is further configured to match the identification information of the powered device acquired by the peripheral interface 402 with the identification information sent by the controller of the powered device, so as to obtain a matching result, and perform identity verification on the powered device based on the matching result.

Here, the peripheral interface 402 is a communication channel for connecting the information acquisition device and the internal control system. The peripheral interface 402 typically supports the standard USB-A protocol and is capable of communicating datA collected by the information acquisition device to the control module 101 for processing in real time. Illustratively, the information acquisition device may be a code scanning device, such as a code scanning gun.

The method comprises the steps of determining that identity verification of the power receiving equipment is not passed under the condition that acquired identification information is inconsistent with the identification information obtained through interaction, and stopping charging the power receiving equipment at the moment.

In some embodiments, after the identity of the powered device passes, the electronic device may further send a control instruction to the powered device to implement changing the operating state of the powered device.
