Based on this, in a first aspect, at least one embodiment of the present disclosure provides a charge conversion device, including: a plurality of power supply interfaces 102 (e.g., type1, type c2, type c3, and type c4 shown in fig. 1) for connecting with a charging apparatus 300 (e.g., a charger) and acquiring power; a charging terminal 101 (e.g. a regulator shown in fig. 1) connected to the plurality of power supply interfaces 102, and configured to connect to a device 200 to be charged and transmit power of the power supply interface 102 to the device 200 to be charged; and a controller 103, connected to the charging terminal 101 and each of the power supply interfaces 102, for controlling the operating power of each of the charging devices 300 connected to the power supply interfaces 102 according to the charging power of the device 200 to be charged connected to the charging terminal 101.

The charging terminal 101 may be connected to the device 200 to be charged through at least one charging interface. If the charging interface can be a socket interface, one end of the data line can be inserted into the charging interface, and the other end of the data line can be inserted into the charging interface of the charged device 200, so that the charging interface is connected with the charged device 200; the charging interface may also be in a plug structure, and the plug may be directly inserted into the device 200 to connect the device 200 to the charging interface.

The power supply interface 102 may be connected to the charging terminal 101 through corresponding charging power chips 106 (e.g., charge 1, charge 2, charge 3, and charge 4 shown in fig. 1), that is, the charging terminal 101 is respectively connected to a plurality of charging power chips 106, and each charging power chip 106 is connected to one power supply interface 102. It can be understood that the charging power chip 106 is disposed on a connection path between the charging terminal 101 and the power supply interface 102, so that it can control power transmission parameters on the connection path, that is, power transmission parameters, such as power transmission power and voltage, used by the power supply power chip to control the corresponding power supply interface 102 to transmit power to the charging terminal 101 according to a control instruction of the controller 103. For example, when each power supply interface 102 transmits power to the charging terminal 101, each charging power chip 106 may control the corresponding power supply interface 102 to transmit power to the charging terminal 101 according to a control instruction of the controller 103, with the same power transmission parameter, for example, the charging voltage is adjusted to 10V. The power supply interface 102 may be in a socket form, and then the output end of the data line of the charging device 300 may be inserted into the power supply interface 102, so as to implement the connection between the power supply interface 102 and the charging device 300; the power supply interface 102 may also be a plug structure, and the plug may be directly inserted into the charging device 300 to connect the charging device 300 and the power supply interface 102.

The controller 103 may be a micro control unit (e.g., MCU shown in fig. 1), which may be connected to the power supply interface 102 to obtain parameters of the power supply interface 102 and parameters for controlling the power supply interface 102, for example, may be connected to each power supply interface 102 through the charging protocol chip 105 to obtain whether each power supply interface 102 is connected to the charging device 300 and the rated power of each charging device 300 through the charging protocol chip 105, and simultaneously, may also control the operating power of each charging device 300 through the charging protocol chip 105; it can also be connected to the charging terminal 101 so as to acquire the charging power of the device 200 to be charged to which the charging terminal 101 is connected.

The charging terminal 101 may be connected to one charged device 200 or to a plurality of charged devices 200, and the charging power of the charged device 200 refers to the maximum charging power of the charged device 200, so the charging power of the charged device 200 connected to the charging terminal 101 may be the maximum charging power of only one charged device 200 connected thereto or the sum of the maximum charging powers of the plurality of charged devices 200 connected thereto.

When the controller 103 controls the operating power of each charging device 300 connected to the power supply interface 102, the connection state of each power supply interface 102 may be obtained first, where the connection state may include whether the charging device 300 is connected and the rated power of the connected charging device 300; then, according to the charging power of the charged device 200 and the connection state of each power supply interface 102, determining the operating power of each charging device 300 connected to the power supply interface 102, for example, the rated powers of the connected charging devices 300 may be summed to obtain a rated total power, then a power supply ratio is obtained according to the rated total power and the charging power of the charged device 200, and then the rated power of each charging device 300 is multiplied by the power supply ratio to obtain the operating power of the charging device 300; and finally, controlling each charging device 300 to transmit electric energy to the corresponding power supply interface 102 according to the determined operating power, and transmitting the electric energy to the charged device 200 connected with the charging terminal 101, so that the charging devices 300 are matched to meet the charging power of the charged device 200.

The charge conversion device further comprises a display screen 107 (e.g. an OLED screen shown in fig. 1), and the display screen 107 is connected to the controller 103, and is used for acquiring the charge state of the charge conversion device from the controller 103 and displaying the charge state.

The charging device 300 may be a charger, and the charged device 200 may be a terminal device such as a smart phone or a tablet power device. The charging conversion device provided by the embodiment can be used between the charger and the terminal device, so that the charging protocol, the charging power and the like can be coordinated, and the charger and the terminal device with different charging protocols can be charged. Moreover, the charging terminal 101 of the charging conversion device can be connected with a plurality of terminal devices, and the plurality of power supply interfaces 102 can be connected with a plurality of chargers, so that the charging conversion device can arrange and distribute the electric energy provided by the chargers in the middle, and therefore, the situation that a plurality of chargers charge one terminal device, or one charger charges a plurality of terminal devices can be realized.

The charging conversion apparatus provided by the embodiment of the present disclosure may be connected to a plurality of charging devices 300 and obtain electric energy from each charging device 300 by providing a plurality of power supply interfaces 102, may be connected to a device 200 to be charged by providing a charging terminal 101 connected to the plurality of power supply interfaces 102, and thus transmit the electric energy obtained by the power supply interfaces 102 to the device 200 to be charged, and may be capable of charging the device 200 to be charged by a plurality of charging devices 300, and further provided with a controller 103 respectively connected to the charging terminal 101 and each power supply interface 102, so as to control the operating power of each charging device 300 connected to the power supply interfaces 102, that is, control the operating power of the connected charging device 300 according to the charging power of the device 200 to be charged connected to the charging terminal 101. Therefore, the charging device 300 connected to each power supply interface 102 can charge the device 200 to be charged connected to the charging terminal 101, and fast charging is realized, the charging device can be adapted to various charging devices 300, so that various charging devices 300 can charge terminal devices, and a plurality of chargers of the same type or different types can charge terminal devices fast together.

In some embodiments of the present disclosure, each of the power supply interfaces 102 is connected to the controller 103 through a corresponding switch unit 104 (e.g., switch1, switch2, switch3, and switch4 shown in fig. 1), each of the switch units 104 is further connected to a charging protocol chip 105, and the charging protocol chip 105 is connected to the controller 103; the switch unit 104 is configured to: after the corresponding power supply interface 102 is accessed to the charging device 300, reporting a device access event of the corresponding power supply interface 102 to the controller 103; the controller 103 is configured to: after the switch unit 104 reports the device access event, the switch unit 104 is controlled to turn on the corresponding power supply interface 102 and the charging protocol chip 105, so that the charging device 300 and the charging protocol chip 105 perform protocol interaction.

After the charging device 300 is connected to the power supply interface 102, protocol interaction is initiated by sending protocol interaction information, and at this time, the switching unit 104 does not conduct the charging protocol chip 105 and the power supply interface 102, so that the protocol interaction information cannot cause further protocol interaction, but can trigger the switching unit 104 to report a device connection event of the corresponding power supply interface 102 to the controller 103, so that the controller 103 can control the switching unit 104 to conduct the corresponding charging protocol chip 105 and the power supply interface 102, so that the charging device 300 and the charging protocol chip 105 perform protocol interaction, and the controller 103 can acquire a charging protocol and a rated power of the charging device 300.

The plurality of power supply interfaces 102 share the charging protocol chip 105, so that if the plurality of power supply interfaces 102 are all connected to the charging device 300, each power supply interface 102 can be sequentially connected according to the connection sequence, protocol interaction is further performed when the connection is performed, and after the protocol interaction is completed and power supply is started, the power supply interface 102 is disconnected, and other power supply interfaces 102 are connected.

In one possible embodiment, the charging conversion apparatus includes a plurality of charging protocol chips 105 connected to the controller 103, each of the charging protocol chips 105 is connected to each of the switch units 104, and each of the charging protocol chips 105 is used for protocol interaction of at least one charging protocol. For example, the plurality of charging protocol chips 105 include a BC (battery charging) protocol chip and a PD (power delivery) protocol chip, the BC protocol chip is used for protocol interaction of charging protocols such as QC3.0, QC2.0, DCP, CDD, USB, and the PD protocol chip is used for protocol interaction of charging protocols such as PD3.0 and PD 2.0. Based on this, the controller 103 is configured to: after the switch unit 104 reports the device access event, the switch unit 104 is controlled to turn on the corresponding power supply interface 102 and each charging protocol chip 105, so that the charging device 300 performs protocol interaction with the corresponding charging protocol chip 105.

Each of the charging protocol chips 105 is connected to a different pin of the switch unit 104, and the pin connected to the charging protocol chip 105 is used for protocol interaction of a charging protocol corresponding to the charging protocol chip 105. The connection between the switch unit 104 and the corresponding power supply interface 102 is a corresponding connection of all pins, so that the charging protocol chip 105 can be connected to different pins of the power supply interface 102 through the switch unit 104. For example, the BC protocol chip is connected to the DM pin and the DP pin of each switch unit 104, and thus the BC protocol chip can be connected to the DM pin and the DP pin of each charging interface through the switch unit 104. That is to say, after the charging device 300 accessed by the power supply interface 102 is connected, the charging device 300 initiates protocol interaction with the charging protocol supported by the charging device 300, and the protocol interaction process of the charging protocol interacts with one or more pins, and after the corresponding switch unit 104 is turned on, the pin turns on the charging interface and the corresponding charging protocol chip 105, so that the charging protocol chip 105 can perform protocol interaction with the newly accessed charging device 300, and other charging protocol chips 105 do not participate in the protocol interaction process.

In some embodiments of the present disclosure, referring to fig. 2, the charging conversion apparatus further includes a plurality of charging interfaces 108 (e.g., typec5, typec6, typec7, and typec8 shown in fig. 2), connected to the charging terminal 101, for connecting to the device 200 to be charged, and transmitting the electric energy transmitted from the charging device 300 to the charging terminal 101 to the device 200 to be charged; the controller 103 is connected to each charging interface 108, and is configured to control electric energy transmission power of each charging interface 108 according to a connection state of each charging interface 108.

The charging interface 108 may be connected to the charging terminal 101 through corresponding charging power chips 106 (e.g., charge 5, charge 6, charge 7, and charge 8 shown in fig. 2), that is, the charging terminal 101 is respectively connected to a plurality of charging power chips 106, and each charging power chip 106 is connected to one charging interface 108. It can be understood that the charging power chip 106 is disposed on a connection path between the charging terminal 101 and the charging interface 108, so that it can control the power transmission power on the connection path, that is, the controller 103 is configured to control the power transmission power of the corresponding charging interface 108 through the charging power chip 106. Each charging power chip 106 is capable of distributing the electric energy of the charging terminal 101, i.e. to at least one charging interface 108. If the charging interface 108 can be a socket interface, one end of the data line can be inserted into the charging interface, and the other end of the data line can be inserted into a charging interface of the terminal device, so that the charging interface 108 is connected with the terminal device; the charging interface 108 may also be a plug structure, and the plug may be directly inserted into the terminal device to connect the terminal device and the charging interface 108.

The connection state of charging interface 108 may include whether charging interface 108 accesses charged device 200, and the charging protocol and charging power of the accessed charged device 200, where the charging protocol of charged device 200 refers to the unique charging protocol supported by charged device 200, or the optimal charging protocol among a plurality of charging protocols supported by charged device 200, and the charging power of charged device 200 refers to the maximum charging power.

When the controller 103 controls the power transmission power of each charging interface 108 according to the connection state of each charging interface 108, the power transmission power of the charging interface 108 which is not connected to the device 200 to be charged may be set to 0, that is, the power is not transmitted to the charging interface 108, and the power transmission power of the charging interface 108 which is connected to the device 200 to be charged is set to the charging power of the device 200 to be charged which is connected to the charging interface 108.

The charge conversion device further comprises a display screen 107 (e.g. an OLED screen as shown in fig. 1), and the display screen 107 is connected to the controller 103 for acquiring the charge state of the charge conversion device from the controller 103 and displaying the charge state.

In one possible embodiment, each of the charging interfaces 108 is connected to the controller 103 through a corresponding switch unit 104 (e.g., switch5, switch6, switch7, and switch8 shown in fig. 2), each of the switch units 104 is further connected to a charging protocol chip 105, and the charging protocol chip 105 is connected to the controller 103; the switch unit 104 is configured to: after the corresponding charging interface 108 is accessed to the charged device 200, reporting a device access event of the corresponding charging interface 108 to the controller 103; the controller 103 is configured to: after the switch unit 104 reports the device access event, the switch unit 104 is controlled to turn on the corresponding charging interface 108 and the charging protocol chip 105, so that the charged device 200 and the charging protocol chip 105 perform protocol interaction.

After the charged device 200 is connected to the charging interface 108, protocol interaction is initiated by sending protocol interaction information, and at this time, the switching unit 104 does not connect the charging protocol chip 105 and the charging interface 108, so that the protocol interaction information cannot cause further protocol interaction, but can trigger the switching unit 104 to report a device connection event of the corresponding charging interface 108 to the controller 103, so that the controller 103 can control the switching unit 104 to connect the corresponding charging protocol chip 105 and the charging interface 108, so that the charged device 200 and the charging protocol chip 105 perform protocol interaction, and the controller 103 can acquire the charging protocol and the charging power of the charged device 200.

The charging interfaces 108 share the charging protocol chip 105, so that if the charging interfaces 108 are all connected to the charged device 200, each charging interface 108 can be sequentially connected according to the connection sequence, protocol interaction is performed when the charging interfaces are connected, and after the protocol interaction is completed and charging is started, the charging interface 108 is disconnected, and other charging interfaces 108 are connected.

Optionally, the charging conversion apparatus 100 includes a plurality of charging protocol chips 105 connected to the controller 103, each of the charging protocol chips 105 is connected to each of the switch units 104, and each of the charging protocol chips 105 is used for protocol interaction of at least one charging protocol. For example, the plurality of charging protocol chips include a BC protocol chip (i.e., BC1.2_ PHY shown in fig. 2) and a PD protocol chip (i.e., PD _ PHY shown in fig. 2), the BC protocol chip is used for protocol interaction of charging protocols such as QC3.0, QC2.0, DCP, CDD, USB, and the PD protocol chip is used for protocol interaction of charging protocols such as PD3.0, PD 2.0. Based on this, the controller 103 is configured to: after the switch unit 104 reports the device access event, the switch unit 104 is controlled to turn on the corresponding charging interface 108 and each charging protocol chip 105, so that the charged device 200 and the corresponding charging protocol chip 105 perform protocol interaction.

Each of the charging protocol chips 105 is connected to a different pin of the switch unit 104, and the pin connected to the charging protocol chip 105 is used for protocol interaction of a charging protocol corresponding to the charging protocol chip 105. The connection between the switch unit 104 and the corresponding charging interface 108 is a corresponding connection of all pins, so that the charging protocol chip 105 can be connected with different pins of the charging interface 108 through the switch unit 104. For example, the BC protocol chip is connected to the DM pin and the DP pin of each switch unit 104, and thus the BC protocol chip can be connected to the DM pin and the DP pin of each charging interface 108 via the switch unit 104. That is to say, after the charged device 200 is accessed by the charging interface 108, the charged device 200 initiates protocol interaction with the charging protocol supported by the charged device 200, and the protocol interaction process of the charging protocol interacts with one or more pins, and after the corresponding switch unit 104 is turned on, the pin turns on the charging interface 108 and the corresponding charging protocol chip 105, so that the charging protocol chip 105 can perform protocol interaction with the newly accessed charged device 200, and other charging protocol chips 105 do not participate in the protocol interaction process.

In step S501, the charging power of the device to be charged to which the charging terminal of the charge conversion apparatus is connected is acquired.

Alternatively, the step of acquiring the charging power of the device to be charged to which the charging terminal of the charging conversion apparatus is connected in the manner shown in fig. 6 includes substeps S5011 to substep S5013.

In step S5011, the connection state of each charging interface of the charge conversion device is acquired.

Firstly, after a switch unit reports a device access event of a corresponding charging interface, the switch unit is controlled to conduct the corresponding charging interface and a charging protocol chip, wherein the device access event is generated when the switch unit accesses a charged device in the corresponding charging interface. If the charging conversion device is provided with a plurality of charging protocol chips, and each charging protocol chip is used for protocol interaction of different charging protocols, the switch unit can be controlled to conduct the corresponding charging interface and each charging protocol chip.

And then, controlling the charging protocol chip to perform protocol interaction with the charged device accessed on the charging interface so as to obtain the charging protocol and the charging power of the charged device. If the charging conversion device is provided with a plurality of charging protocol chips, each charging protocol chip is connected with different pins of the switch unit, and the pins connected with the charging protocol chips are used for protocol interaction of the charging protocol corresponding to the charging protocol chips, so that the charging protocol chips corresponding to the pins and the charged equipment can be controlled to perform protocol interaction according to the pins used by the charged equipment for initiating the protocol interaction.

It is understood that this step needs to be performed for each charging interface of the charge conversion device. If the switch unit corresponding to a certain charging interface does not report the device access event, the connection state of the charging interface is acquired as the device which is not accessed to the charged device, and if the switch unit corresponding to a certain charging interface reports the device access event, the charging protocol and the charging power of the device which is accessed to the charging interface are acquired according to the steps. And if the equipment access events are reported by the plurality of charging interfaces, sequentially acquiring the charging protocol and the charging power of the charged equipment accessed by each charging interface according to the reporting sequence.

In sub-step S5012, the charging power of the device to be charged to which the charging terminal is connected is determined according to the connection state of each of the charging interfaces.

Optionally, the sum of the charging power of each charged device connected to the charging interface is determined as the charging power of the charged device connected to the charging terminal.

In step S502, the connection state of each power supply interface of the charge conversion device is acquired.

Firstly, after a switch unit reports an equipment access event of a corresponding power supply interface, the switch unit is controlled to conduct the corresponding power supply interface and a charging protocol chip, wherein the equipment access event is generated when the switch unit accesses charging equipment in the corresponding power supply interface. If the charging conversion device has a plurality of charging protocol chips, and each charging protocol chip is used for protocol interaction of different charging protocols, the switch unit can be controlled to conduct the corresponding power supply interface and each charging protocol chip.

And then, controlling the charging protocol chip to perform protocol interaction with the charging equipment accessed on the power supply interface so as to obtain a charging protocol and rated power of the charging equipment. If the charging conversion device is provided with a plurality of charging protocol chips, each charging protocol chip is connected with different pins of the switch unit, and the pins connected with the charging protocol chips are used for protocol interaction of the charging protocol corresponding to the charging protocol chips, so that the charging protocol chips corresponding to the pins and the charging equipment can be controlled to perform protocol interaction according to the pins used by the charging equipment for initiating the protocol interaction.

It will be appreciated that this step needs to be performed for each power supply interface of the charge conversion device. If the switch unit corresponding to a certain power supply interface does not report the device access event, acquiring that the connection state of the power supply interface is the charging device which is not accessed, and if the switch unit corresponding to a certain charging interface reports the device access event, acquiring the charging protocol and the rated power of the charging device which is accessed by the power supply interface according to the steps. And if the equipment access events are reported by the plurality of power supply interfaces, sequentially acquiring the charging protocol and the rated power of the charging equipment accessed by each power supply interface according to the reporting sequence.

In step S503, the operating power of each charging device connected to the power supply interface is determined according to the charging power and the connection state of each power supply interface.

Optionally, the rated power of each charging device that is accessed is summed to obtain a rated total power, then a power supply ratio is obtained according to the rated total power and the charging power of the charged device that is accessed to the charging end, and then the rated power of each charging device is multiplied by the power supply ratio to obtain the operating power of the charging device.

In step S504, each charging device is controlled to transmit electric energy to the corresponding power supply interface according to the determined operating power, and transmit the electric energy to the device to be charged connected to the charging terminal.

When each power supply interface transmits electric energy to a charging terminal, the charging power chip corresponding to each power supply interface may be controlled to adjust an electric energy transmission parameter of the power supply interface for transmitting electric energy to the charging terminal to a preset parameter, for example, adjust a voltage to 10V.
