Description

Technical Field

[0001] The present invention relates to the technical field of portable power supplies, and more particularly to a power output distribution device and method for a power supply circuit. Background Art

[0002] With the explosive growth of smart phones and laptops, and the rapid growth of new energy electric vehicles, photovoltaic industry and energy storage equipment, there are more and more electronic power modules and mobile power products. The products are getting smaller and smaller. Lithium batteries are widely used in mobile devices. When designing each product, a specific charging plan will be formulated according to the characteristics of the selected battery to complete the charging of the device in the fastest and safest way. Because lithium batteries are flammable and explosive, for safety reasons, each company has its own encrypted private protocol (generally not open to the public, except for authorization), and the mutual compatibility is not good. In order to make mobile devices more convenient and quick to use, the charging speed is getting faster and faster, and the power required is getting higher and higher. How to redistribute and expand the application of various adapters. Compatibility, practicality and convenient monitoring applications have become a new topic. It is an urgent problem to increase and expand the compatibility of other output ports without changing all the original performance of the adapter.

[0003] In practice, high-power output devices have a single application scenario. For example, a mobile phone charger with a nominal power of 240W actually uses a peak power of 213W for only a few seconds, and only uses 20-40W for charging most of the time, which is very wasteful. After charging the mobile phone, most of the energy can be allocated to charging other devices, but it cannot be used due to the one output port.

[0004] For example, a mobile phone charger with a nominal output voltage of 150W can only output a maximum voltage of 11V, which cannot be used on many devices including notebooks. In addition, the USB charging protocol is changing with each passing day as products are upgraded. The PD3.0 adapter can only support a maximum output voltage of 20V and cannot provide the functions of devices that support PD3.1.

[0005] When mobile phone manufacturers launch new products (increasing battery capacity and shortening charging time), they will develop the best charging solution (i.e. fast and safe) based on the characteristics of the selected batteries. They will not consider compatibility with other brands of charging devices and will often only be equipped with a single port. If you want to charge multiple devices at the same time, you must buy multiple charging heads or buy more expensive charging heads with multiple ports (this type of device can charge the phone, but it is not necessarily the best charging solution, such as slow charging time and charging safety is not as good as the original one), and the compatibility and expansion performance are not strong.

[0006] Similarly, electric vehicles also use lithium batteries. In order to charge quickly and safely, they are also charged very quickly at the beginning. When the battery temperature reaches the safety warning point (in a very short time), the charging power will be quickly reduced. This method can greatly improve the power utilization of the charging pile and increase the capacity of the charging pile exponentially.

[0007] Nowadays, competition in all walks of life is very fierce. The same is true for the power supply industry. For example, if you release a charger or power bank with two ports today, I will release a charger with three ports tomorrow, and a charger with four ports the day after tomorrow. Every time an update is made, all the structures and circuits of the product are redesigned because it is a mandatory certification product. Each product must obtain product certification (including UL, CE, CB, PCT (Russia), ETL, TUV (Germany), EN (Europe), CSA (Canada), GS (Germany), NF (France, FCC, IEC, CQC, 3C, PSE (Japan), RoHS, SASO, SAA and other standards). This practice will cause too much waste of manpower, materials and energy in design and production.

[0008] Due to the single function and low practicality of the product, the charging equipment is updated quickly and the functional requirements are getting higher and higher. In order to meet the equipment requirements, we have to re-purchase expensive multi-port and new requirements such as PD3.1 products. The circuit must meet the requirements of high-voltage AC mains through EMI circuit, AC-DC control circuit, high-voltage gallium nitride switch tube, isolation transformer, DC-DC and port protocol circuit, and various certification certificates that waste financial and material resources, resulting in high costs.

[0090] like Figure 1 As shown, the power output distribution device for a power supply circuit proposed in the present invention (hereinafter referred to as the present device) 1 includes a control unit (including an AI control unit) 100, an input end, and an output end. There is at least one input end, which is respectively connected to the control unit 100, each input end is used to connect to a power supply device or a power adapter, and the input end is used to obtain power information (including voltage, current, power, maximum temperature, etc.) of the power supply device or the power adapter. There is at least one output end, which is connected to the control unit, each output end is used to connect to an electrical device, and the output end is used to obtain power information (including voltage, current, power, maximum temperature, etc.) of the electrical device.

[0091] In the present invention, the power circuit having at least one pair of input terminals and output terminals and the data circuit are directly connected or connected through a control switch, or the power circuit having at least one pair of input terminals and output terminals is directly connected or connected through a control switch;

[0092] The control unit 100 obtains input power through the input end, and redistributes it to each output end according to the output power of each output end, and adjusts the optimal input voltage and current according to the output voltage and current requirements.

[0093] In cases where a dedicated power supply device or power adapter can only charge a single device, has a small output voltage range (small voltage and high current), has few application scenarios, or has a high-power power supply device but an extremely short high-power charging time, the combined application of this device and the power supply device or power adapter can expand the practicality and application scope of the original product by adjusting the voltage range, expanding the output port, and re-allocating the output power in an intelligent and controllable manner without changing the performance and compatibility of the original power supply device or power adapter.

[0094] For example, when a 240W charger is actually used, the 213W peak charging time is only a few seconds, and most of the time the charging power is only 20-40W (the power utilization rate is less than 20%). The maximum output voltage of a 150W charger is only 11V (a 150W laptop cannot be used). These two chargers are too wasteful. Combining these two chargers with this device will not change the previous fast charging performance and safety, and can also meet the current applications of most mobile terminal devices and charge multiple devices at the same time. This device completes the conversion through a combination of DC-DC converters, which is extremely low cost, easy to update and upgrade, very easy to authenticate, and can be controlled by Ai smart (via wireless module, OTA update is possible).

[0095] like Figure 1 In the first embodiment, there is one input terminal, namely input terminal one 131, and there are three output terminals, namely output terminal one 161, output terminal two 162 and output terminal three 163.

[0096] The device has three power output circuits, the first power output circuit is directly connected to the input terminal 131 and the output terminal 1 161; the second power output circuit is connected to the input terminal 1 131 and the output terminal 2 162 through the first DC converter 111; the third power output circuit is connected to the input terminal 1 131 and the output terminal 3 163 through the second DC converter 112.

[0097] At the same time, the communication data line of the input terminal 131 is directly connected to the communication data line of the output terminal 161. In this way, the power signal and data signal of the input terminal 131 are directly connected to the output terminal 161, which is equivalent to the first port 261 of the power adapter 2 being directly connected to the power-consuming device port 331. Obviously, after the power adapter 2 is connected to the device 1, it still has all the performance characteristics and load capacity (same compatibility and safety) of the original power adapter, and realizes the expansion of new functions without changing the original performance of the power adapter.

[0098] The control unit 100 is respectively connected to the input terminal 131 , the output terminal 161 , the output terminal 2 162 , the output terminal 3 163 , the current sensor Rcs1 , the current sensor Rcs3 , the current sensor Rcs4 , the current sensor Rcs5 , the first DC converter 111 , and the second DC converter 112 .

[0099] In this embodiment, two situations are specifically described: one in which an electric device is connected to the output terminal 161 and the other in which an electric device is not connected.

[0100] When the output terminal 161 is connected to an electrical device:

[0101] The control unit 100 obtains the power information (including the maximum voltage, maximum current and rated power) that the power adapter 2 can provide to the input terminal 131 through the input terminal 131. The information of the connected power device (including the voltage and current to be output) is obtained through the output terminal 161, the output terminal 2 162 and the output terminal 3 163. The output of the output terminal 161 is completely determined by the protocol between the power adapter 2 and the power device 1 port 331, and is not controlled by the control unit 100, that is, it gives priority to meeting the requirements of the charging device connected to the output terminal 161. The control unit 100 analyzes and calculates the maximum power P131imax@V331 that the input terminal 131 can provide under the current voltage, subtracts the power output of the output terminal 161 Pom=V331*I331, and obtains the remaining power Pirem after removing the output terminal 161, and distributes it to the power devices connected to the output terminal 2 162 and the output terminal 3 163 by controlling the first DC converter 111 and the second DC converter 112. The efficiency is as follows:

[0102] η=(Pom+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131).

[0103] In fact, the control unit efficiency should be calculated as follows: Ignoring the loss V161=V331, V162=V332, V163=V333, all examples are represented by V331, V332, V333, I331, I332, I333 to represent V161, V162, V163, I161, I162, I163 respectively, and will not be repeated here.

[0104] η=(Pom+Po1+Po2) / Pi=(V161*I161+V162*I162+V163*I163) / (V131*I131).

[0105] The following are the output specifications of a mobile phone adapter:

[0106] If there is only one Type C port, the voltage and current output specifications are: 3.3-5V / 8A Max, 5.2-11V / 9.1A Max, 12-18V / 10A Max, 20V / 12A Max;

[0107] When the voltage V331 = 20V, the maximum output power P131imax@20V = 20*12 = 240W;

[0108] When the voltage V331 = 15V, the maximum output power P131imax@15V = 15*10 = 150W;

[0109] When the voltage V331 = 11V, the maximum output power P131imax@11V = 11*9.1 = 100W;

[0110] When the voltage V331 = 5V, the maximum output power P131imax@5V = 5*8 = 40W.

[0111] It can be seen that the maximum output power of the power adapter 2 will change with the change of the voltage V331 (V331=V131) (ignoring the loss and retaining some margin for actual application).

[0112] When the output terminal 161 charges the mobile phone, the initial voltage is V331 (V331=20V) and the current is 12A, but the time is very short and the power is around 20-40W most of the time.

[0113] When the power adapter 2 charges the electrical device at port 331 with a power of 40W, the voltage V331 = 20V. At this time, the power that can be provided to the output terminal 2 162 and the output terminal 3 163 is 240W-40W=200W (ignoring the loss and leaving some margin), and 80% of the energy is available to charge other electrical devices (three output terminals are provided in this embodiment, and four, five, six, etc. output terminals may also be provided).

[0114] The maximum output voltage of the power adapter 2 is 20V, which can meet the needs of PD3.0 power devices, but cannot meet the needs of PD3.1 power devices (such as V=28V, 36V, 48V).

[0115] Selecting Boost or Buck-Boost topology circuits for the first DC converter 111 and the second DC converter 112 can make the voltage of the output terminal 2 162 and the output terminal 3 163 become 28V, 36V, or 48V.

[0116] The power adapter 2 can be compatible with PD3.1 products when used in conjunction with the device 1, thus expanding the practicability and application scope of the product.

[0117] When the output terminal 161 is not connected to an electrical device:

[0118] The control unit 100 obtains the power information (including the maximum voltage, maximum current and rated power) that the power adapter 2 can provide to the input terminal 1 131 through the input terminal 1 131, and obtains the information of the connected power device (including the voltage and current required to be output) through the output terminal 2 162 and the output terminal 3 163.

[0119] The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage of the first DC converter 111 and the second DC converter 112 .

[0120] The efficiency η = (Po1 + Po2) / Pi = (V332 * I332 + V333 * I333) / (V131 * I131), the voltage adapter can provide different energy (load capacity) at different output voltages. The control unit 100 selects the following requirements according to the priority level:

[0121] (1) Satisfy all energy requirements of output terminal 2 162 and output terminal 3 163 and have high efficiency;

[0122] (2) not satisfying the full energy of output terminal two 162 and output terminal three 163, and providing sufficient energy;

[0123] (3) It does not satisfy that the output terminal two 162 and the output terminal three 163 have all the energy, provide the same energy, and have high efficiency.

[0124] The control unit 100 first takes the maximum voltage Vimax (or not) that the power adapter 2 can output as the input voltage of the first DC converter 111 or the second DC converter 112. At this time, the maximum power of the first port 261 of the power adapter 2 is P261@20V (such as the parameters of the 240W power adapter above, the power when the maximum voltage is 20V is P261@20V=240W). The control unit 100 supplies power to the electrical equipment connected to the output terminal 2 162 and the output terminal 3 163 by adjusting the output of the first DC converter 111 and the second DC converter 112. The efficiency η=(Po1+Po2) / Pi=(V332*I332+V333*I333) / (V131*I131).

[0125] Gradually reduce the voltage V261 and calculate the efficiency η at this time. Quickly determine all voltages that can provide all energy or enough energy to the output terminal 2 162 and the output terminal 3 163, and take the voltage with the highest efficiency η as the input voltage of the first DC converter 111 or the second DC converter 112.

[0126] The control unit 100 analyzes and calculates that the maximum power that the input terminal 1 131 can provide under the current voltage is P131imax@V331, and the control unit 100 distributes the power to the electrical equipment connected to the output terminal 2 162 and the output terminal 3 163 by controlling the first DC converter 111 and the second DC converter 112.

[0127] The above method retains all the performance of the original power adapter and monitors the efficiency η in real time, intelligently selects the input conditions (voltage, current, power) when the efficiency η is the highest, and controls the first DC converter 111 and the second DC converter 112 through the control unit 100 to allocate them to the electrical equipment connected to the output terminal 2 162 and the output terminal 3 163. The control is relatively complex.

[0128] There is another method with high cost performance and simple control: the first DC converter 111 and the second DC converter 112 are Buck converters.

[0129] When the output terminal 1 161 is just connected to the power device, during high-power charging, such as voltage V331 = 20V (charging starts or connected to a laptop), if the voltage difference ΔV≈1.5V between the first DC converter 111 and the second DC converter 112, the output voltage range of the output terminal 2 162 and the output terminal 3 163 is 0-18.5V, and the application scenarios are relatively wide. When the mobile phone is almost fully charged, the voltage drops to V331 = 5V, and the output voltage of the output terminal 2 162 and the output terminal 3 163 is 0-3.5V, and the application scenarios are relatively few (but the third embodiment can solve this problem).

[0130] When the output terminal 161 is not connected to an electrical device, the voltage Vomax = V332. When the voltage V333 is a high voltage, it changes dynamically.

[0131] The control unit 100 obtains the power information (including the voltage and current to be output) of the connected power-consuming device through the output terminal 2 162 and the output terminal 3 163. The control unit 100 requires the voltage V261 of the first port 261 of the power adapter 2 to be greater than or equal to Vomax+ΔV. The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage of the first DC converter 111 or the second DC converter 112. The efficiency η=(Po1+Po2) / Pi=(V332*I332+V333*I333) / (V131*I131) can be obtained.

[0132] The power adapter 2 can provide different energies (load capacity) when outputting different voltages. The control unit 100 selects the following requirements according to the priority level:

[0133] (1) Satisfy all energy requirements of output terminal 2 162 and output terminal 3 163 and have high efficiency;

[0134] (2) not satisfying the full energy of output terminal two 162 and output terminal three 163, and providing sufficient energy;

[0135] (3) It does not satisfy that the output terminal two 162 and the output terminal three 163 have all the energy, provide the same energy, and have high efficiency.

[0136] The above method retains all the performance of the original power adapter and monitors the efficiency η in real time, intelligently selects the input conditions (voltage, current, power) when the efficiency η is the highest, and controls the first DC converter 111 and the second DC converter 112 through the control unit 100 to allocate them to the electrical equipment connected to the output terminal 2 162 and the output terminal 3 163. The control is relatively complex.

[0137] It is also possible to directly take the voltage V261=V261max. Usually, the voltage is the highest at this time, and the power adapter 2 can output a larger power, such as the 240W power adapter mentioned above, the power P261=240W@20V. The control unit 100 distributes the corresponding voltage and current to the power-consuming devices connected to the output terminal 2 162 and the output terminal 3 163 by controlling the first DC converter 111 and the second DC converter 112. If a power adapter with an output voltage higher than the PD3.0 or PD3.1 voltage ΔV is connected, the device can adjust the input voltage through the protocol to meet the power supply of the PD3.0 and PD3.1 devices.

[0138] For example: the control unit 100 adjusts the voltage V261 = 21-22V through the protocol, so that after Buck, the voltage V332 = 20V or V333 = 20V, which meets PD3.0;

[0139] The control unit 100 adjusts the voltage V261 = 29-30V through the protocol, so that after Buck, the voltage V332 = 28V or V333 = 28V, which meets PD3.1;

[0140] The control unit 100 adjusts the voltage V261 = 37-38V through the protocol, so that after Buck, the voltage V332 = 36V or V333 = 36V, which meets PD3.1;

[0141] The control unit 100 adjusts the voltage V261 = 49-50V through the protocol, so that after Buck, the voltage V332 = 48V or V333 = 48V, meeting PD3.1.

[0142] In this method, the first DC converter 111 and the second DC converter 112 are Buck, which has low cost, high cost performance and simple control. However, the PD3.0 power adapter cannot meet the requirements of upgrading to PD3.1 when used with this device (the second embodiment can solve this problem).

[0143] In the first embodiment, the second output terminal 162 is connected to the second port 332 of the electric device, and the third output terminal 163 is connected to the third port 333 of the electric device.

[0144] like Figure 2 As shown, the difference between the second embodiment and the first embodiment is that a third DC converter 113 is added between the input terminal 131 and the first DC converter 111 and the second DC converter 112. By changing the DC converter topology combination between them, different scene applications can be realized, which can solve the shortcoming mentioned in the first embodiment that the PD3.0 power adapter combined with the present device 1 cannot meet the charging requirements of the PD3.1 electrical equipment.

[0145] When the first DC converter 111 and the second DC converter 112 are Buck converters, adding the third DC converter 113 for boost or buck-boost can be easily achieved.

[0146] like Figure 3 As shown, the difference between the third embodiment and the first embodiment is that two switch units, a first switch unit 121 (power switch) and a second switch unit 122 (a group of data switches), are added between the input terminal 131 and the output terminal 161. The first switch unit 121 is a power signal on-off switch, and the second switch unit 122 is a data signal on-off switch.

[0147] The first DC converter 111 and the second DC converter 112 use Buck (this circuit has low cost and simple control, but is not limited to this), and the output terminal 161 is connected to the load.

[0148] When the mobile phone is almost fully charged, the voltage of the first port 331 of the power-consuming device will drop to V331=5V. When the mobile phone is almost fully charged, if the voltage difference ΔV≈1.5V between the first DC converter 111 and the second DC converter 112, the output voltage of the output terminal 2 162 and the output terminal 3 163 is 0-3.5V, and there are fewer application scenarios (refer to the first embodiment).

[0149] When the control unit 100 detects that the first port 331 of the power-consuming device is fully charged, the first switch unit 121 and the second switch unit 122 are disconnected, and the voltage V261 of the first port 261 of the power adapter 2 is reset, such as V261max, or the voltage at which the power adapter 2 outputs the maximum power. If the output terminal 1 161 is not connected to the power adapter 2 originally provided with the power-consuming device, or the power adapter 2 originally provided with the power-consuming device needs to be charged preferentially to the power-consuming devices connected to the output terminals 2 162 and 3 163 (those with wireless modules can be set by the App), the method of setting V261=V261max can be adopted.

[0150] like Figure 4As shown, the difference between the fourth embodiment and the third embodiment is that a third DC converter 113 is added between the input terminal 131 and the first DC converter 111 and the second DC converter 112. The purpose is the same as that of the first embodiment.

[0151] like Figure 5 As shown, the difference between the fifth embodiment and the first embodiment is that an input terminal 2 132 and an output terminal 4 166 are added, and both the input terminal 2 132 and the output terminal 4 166 are DC power interfaces.

[0152] The input terminal 2 132 is output through three power output circuits, the first power output circuit is the direct connection between the input terminal 2 132 and the output terminal 4 166; the second power output circuit is the input terminal 2 132 connected to the first DC converter 111 and then connected to the output terminal 2 162; the third power output circuit is the input terminal 2 132 connected to the second DC converter 112 and then connected to the output terminal 3 163.

[0153] The traditional power adapter is a DC interface, the input terminal 2 132 is connected to the third port 263 of the power adapter 2, and the output terminal 4 166 is connected to the fourth port 336 of the power device (the original charging device interface), so that the traditional power adapter can charge the original charging device while supplying excess energy to the second port 332 and the third port 333 of the power device.

[0154] The current that can pass through the existing interfaces with data signals and power signals (such as USBA and USBC interfaces) is too small, generally only 5-6A at most. By using the existing integrated interface with data signals and power signals and taking data information as the protocol communication channel, the DC interface can pass large current.

[0155] Only one of the power interfaces of input terminal 1 131 and input terminal 2 132 is used at the same time (or not, which is not shown in the diagram), or input terminal 1 131 is used as a data information interface and input terminal 2 132 is used as a high-power power interface.

[0156] like Figure 6 The difference between the sixth embodiment and the fifth embodiment is that a third DC converter 113 is added between the input terminal 131, the input terminal 2 132 and the first DC converter 111, the second DC converter 112, and different scene applications can be realized by changing the power conversion topology combination between them.

[0157] Figure 7 , Figure 8 and Fig. 9 A wireless module is added to facilitate intelligent control. The device is connected to the terminal and the control is completed through the APP.

[0158] like Figure 7 The difference between the seventh embodiment and the sixth embodiment is that the device is provided with a wireless module for intelligent control. The wireless module includes but is not limited to Zeebe, Wifi, Bluetooth, Lora, 4G, 5G, 6G and Huawei's Star Flash, etc.

[0159] In this embodiment, an internal wireless circuit unit 102 is provided, and the internal wireless circuit unit 102 is connected to the control unit 100. The internal wireless circuit unit 102 is provided in the device (refer to Fig.18 , or connected to the USB interface through the external wireless circuit unit 104), so that the device can be wirelessly connected to mobile phones, tablets and computers, and corresponding programs (such as App) installed on them can clearly display the charging status, and can adjust the priority level of charging control and remote intelligent control system through the Internet. It can realize functions such as remote monitoring of charging status, control switch, power distribution, timed power off, and timed charging.

[0160] like Figure 8 The difference between the eighth embodiment and the fifth embodiment is that a first switch unit 121 (power switch), a second switch unit 122 (a group of data switches), a third switch unit 123 (power switch) and an internal wireless circuit unit 102 are added.

[0161] Only one of the power interfaces of input terminal 1 131 and input terminal 2 132 can be connected and used at the same time. (It may not be the case, which is not shown in the diagram)

[0162] This embodiment has three output applications and control methods:

[0163] The first type: the input terminal 131 is output through three power output circuits, the first power output circuit is the input terminal 131 connected to the first switch unit 121 and then connected to the output terminal 1 161, the second power output circuit is the input terminal 131 connected to the output terminal 2 162 through the first DC converter 111, and the third power output circuit is the input terminal 131 connected to the output terminal 3 163 through the second DC converter 112.

[0164] The communication data line of the input terminal 131 is connected to the communication data line of the output terminal 161 through the second switch unit 122 .

[0165] The above is a general USB power control method, where the current, voltage and power are relatively small.

[0166] The second type: the input terminal 2 132 is output through three power output circuits, the first power output circuit is the input terminal 2 132 connected to the third switch unit 123 and then connected to the output terminal 4 166, the second power output circuit is the input terminal 2 132 connected to the first DC converter 111 and then connected to the output terminal 2 162, and the third power output circuit is the input terminal 2 132 connected to the second DC converter 112 and then connected to the output terminal 3 163.

[0167] At this time, the first power output can output high power, but due to the lack of control signal, the power parameters cannot be controlled.

[0168] The third type: the input terminal 2 132 is output through three power output circuits, the first power output circuit is the input terminal 2 132 connected to the third switch unit 123 and then connected to the output terminal 4 166, the second power output circuit is the input terminal 2 132 connected to the first DC converter 111 and then connected to the output terminal 2 162, and the third power output circuit is the input terminal 2 132 connected to the second DC converter 112 and then connected to the output terminal 3 163. The communication data line of the input terminal 1 131 is connected to the communication data line of the output terminal 1 161 through the second switch unit 122.

[0169] At this time, the transmission of high current, high voltage and high power has a set of input terminals, namely, input terminal 131 is the first data signal input terminal, input terminal 2 132 is the first high power input terminal, and also has a set of output terminals, namely, output terminal 1 161 is the first data signal output terminal, and output terminal 4 166 is the first high power output terminal.

[0170] The first power output circuit is through a set of input interfaces, namely, the first input terminal 131 and the output terminal 161. The first input terminal 131 (only a data interface at this time) and the output terminal 161 (only a data interface at this time) obtain power information (voltage, current, power) through the second input terminal 132 (high power interface) and the output terminal 166 (high power interface) channels, and the control unit 100 controls the second switch unit 122 (data switch) and the third switch unit 123 (power switch) to achieve high power output.

[0171] Figure 8 The medium power adapter 2 also includes a set of data ports (ie, the first port 261 ) and a high-power power interface (ie, the third port 263 ).

[0172] The electric device 3 also includes a group of data ports (ie, the electric device one port 331 ) and a high-power power interface (ie, the electric device four port 336 ).

[0173] The internal wireless circuit unit 102 is connected to the control unit 100 .

[0174] like Fig. 9The difference between the ninth embodiment and the eighth embodiment is that a third DC converter 113 is added between the input terminal 1 131 , the input terminal 2 132 and the first DC converter 111 , the second DC converter 112 .

[0175] As above, only one connection of the power interface of input terminal 1 131 and input terminal 2 132 is used at the same time (it may not be, which is not shown in the diagram), or input terminal 1 131 is used as a data information interface and input terminal 2 132 is used as a high-power power interface.

[0176] like Fig.10 The tenth embodiment differs from the third embodiment in that a fifth DC converter 115 is added, and the fifth DC converter 115 is connected in parallel with the first switch unit 121. That is, the first power output circuit is connected to the output terminal 161 via the parallel circuit of the first switch unit 121 and the fifth DC converter 115 and the input terminal 131.

[0177] When the output terminal 1 161 is not connected to the original power adapter 2, or although it is connected to the original power adapter 2, but the output terminal 2 162 and the output terminal 3 163 need to be charged first:

[0178] If the first switch unit 121 and the second switch unit 122 are both turned on, the Figure 1 Circuit structure;

[0179] If the first switch unit 121 and the second switch unit 122 are both disconnected, the Fig.11 (i.e., the circuit structure of the eleventh embodiment);

[0180] If the first DC converter (111), the second DC converter (112) and the fifth DC converter (115) are Buck converters, Fig.12 (i.e., the circuit structure of the twelfth embodiment).

[0181] The voltage Vomax is equal to the highest voltage among V331, V332, and V333, and it changes dynamically.

[0182] The control unit 100 obtains the power information (including the voltage and current to be output) of the connected power-consuming device through the output terminal 1 161, the output terminal 2 162, and the output terminal 3 163. The control unit 100 requires that the voltage V261 of the first port 261 of the power adapter 2 is greater than or equal to Vomax+ΔV. The control unit 100 adjusts the output voltage of the power adapter 2 as the input voltage of the first DC converter 111 and the second DC converter 112, and the efficiency η can be obtained as follows:

[0183] η=(Pom+Po1+Po2) / Pi=(V331*I331V332*I332+V333*I333) / (V131*I131).

[0184] The power adapter 2 can provide different energies (load capacity) at different output voltages. The power adapter 2 is selected to meet the following requirements according to the priority level:

[0185] (1) Satisfying all energy requirements of output terminal 1 161, output terminal 2 162, and output terminal 3 163, with high efficiency;

[0186] (2) not satisfying the full energy of output terminal 1 161, output terminal 2 162, and output terminal 3 163, and providing sufficient energy;

[0187] (3) Not satisfying all the energy of output terminal 1 161, output terminal 2 162, and output terminal 3 163, providing the same energy with high efficiency.

[0188] The tenth embodiment has one more fifth DC converter 115 than the third embodiment. By disconnecting the first switch unit 121, three output ports can be charged simultaneously and the input voltage V131 (V111=V112=V115) of the first DC converter 111, the second DC converter 112 and the fifth DC converter 115 can be made equal.

[0189] =V131)≠V331 (unlike the third embodiment, when the output terminal 161 is connected to the electrical device, the voltage V131=V331 is constrained by the electrical device port 131). It can also monitor the efficiency η in real time, intelligently select the input requirements, and control the first DC converter 111, the second DC converter 112, and the fifth DC converter 115 to distribute the voltage and current to the electrical devices connected to the output terminal 1 161, the output terminal 2 162, and the output terminal 3 163, and has 3 independent output ports, one more than the third embodiment.

[0190] The control unit 100 directly sets the voltage V261=V261max (usually the highest voltage at this time means the power adapter can output a larger power), such as the 240W power adapter mentioned above, the power P261=240W@20V. The control unit 100 distributes the voltage and current to the power-consuming devices connected to the output terminal 1 161, the output terminal 2 162, and the output terminal 3 163 by controlling the fifth DC converter 115, the first DC converter 111, and the second DC converter 112.

[0191] This method is low-cost, cost-effective and easy to control. The PD3.0 power adapter cannot meet the requirements of upgrading to PD3.1 when used with this device (this problem can be solved by adding a third DC converter 113, such as the second embodiment). Buck is a step-down device, so the output voltage becomes smaller. However, this device can adjust the power adapter with a voltage higher than the output voltage of the PD3.0 device through the protocol to meet the power supply of the PD3.1 device. If the output voltage of the connected power adapter is higher than the PD3.0 or PD3.1 voltage ΔV, this device can adjust the input voltage through the protocol to meet the power supply of the PD3.0 and PD3.1 devices.

[0192] For example: the control unit 100 adjusts the voltage V261 = 21-22V through the protocol to meet the voltage V332 = 20V or V333 = 20V after Buck, meeting PD3.0;

[0193] The control unit 100 adjusts the voltage V261 = 29-30V through the protocol to meet the voltage V332 = 28V or V333 = 28V after Buck, meeting PD3.1;

[0194] The control unit 100 adjusts the voltage V261 = 37-38V through the protocol to meet the voltage V332 = 36V or V333 = 36V after Buck, meeting PD3.1;

[0195] The control unit 100 adjusts V261=49-50V through the protocol to meet the voltage V332=48V or V333=48V after Buck, meeting PD3.1.

[0196] The first switch unit 121 and the second switch unit 122 can use mechanical linkage switches (or electronic switches). When the power-consuming device connected to the output terminal 161 uses the original power adapter 2, the first switch unit 121 and the second switch unit 122 are closed, and the optimal charging scheme of the output terminal 161 is preferentially satisfied. The three output terminals are charged at the same time; when the power-consuming device connected to the output terminal 161 does not use the original power adapter 2, the first switch unit 121 and the second switch unit 122 are turned off, and the three output terminals work independently. The output terminal 161 is compatible with the original power adapter and has an additional independently working output port (refer to the first to ninth embodiments).

[0197] like Fig.16The difference between the sixteenth embodiment and the tenth embodiment is that: a fifth switch unit 125 is added, and the fifth switch unit 125 is connected in parallel with the first DC converter 111. A seventh switch unit 127 is added, and the seventh switch unit 127 is connected in parallel with the second DC converter 112. That is, the second power output circuit is the input end 131 connected to the output end 2 162 through the parallel circuit of the fifth switch unit 125 and the first DC converter 111. The third power output circuit is the input end 131 connected to the output end 3 163 through the parallel circuit of the seventh switch unit 127 and the second DC converter 112.

[0198] At the same time, the fourth switch unit 124 and the sixth switch unit 126 are added, so that the communication data line of the input terminal 1 131 is directly connected to the communication data line of the output terminal 1 161 through the second switch unit 122. The communication data line of the input terminal 1 131 is directly connected to the communication data line of the output terminal 2 162 through the fourth switch unit 124. The communication data line of the input terminal 1 131 is directly connected to the communication data line of the output terminal 3 163 through the sixth switch unit 126.

[0199] The advantage of this is that the output ports can be directly connected to the input ports, and all the performance of the original adapter can be obtained. And all ports can simultaneously meet the extremely fast and safe output.

[0200] As in the 240W adapter above, three mobile phones are connected at the same time. The control unit will directly connect the input to the first mobile phone interface (data and power at the same time). At this time, the adapter charges it at 213W high power and extremely fast, and the second and third mobile phones can share the remaining 27W power (for a very short time). When the first mobile phone completes the 213W high power and extremely fast charging, disconnect the pass-through mode of the first mobile phone and switch the second mobile phone to pass-through mode. At this time, the second mobile phone is charged at 213W high power and extremely fast, and the remaining 27W power is shared with the first and third mobile phones. Soon the second mobile phone will also complete the 213W high power and extremely fast charging, and then disconnect its pass-through mode and switch to the third mobile phone. Soon the third mobile phone will also complete the 213W high power and extremely fast charging. Finally, the charging power of the three mobile phones is 40W—>20W (there is still 120W-180W of power left, which can also meet the needs of three mobile phones). All three ports can provide extremely fast and safe charging services at the same time. It can be seen that this 240W adapter can meet the optimal charging method for 6 mobile phones at the same time.

[0201] Obviously, in the sixteenth embodiment, all the output ports of the device can be directly connected to the output ports of the original power adapter (power and data interface) through control, which is much more efficient than the utilization rate of the original adapter in the tenth embodiment. Of course, some of the output ports of the device can also be directly connected to the output ports of the original adapter (not shown).

[0202] like Fig.13 The thirteenth embodiment is different from the first embodiment in that: there are two output terminals, namely output terminal one 161 and output terminal two 162, and a wireless charging transmitter 181 is added.

[0203] The device has three power output circuits, the first power output circuit is a direct connection between the input terminal 131 and the output terminal 161, the second power output circuit is a connection between the input terminal 131 and the output terminal 2 162 through the first DC converter 111, and the third power output circuit is a connection between the input terminal 131 and the wireless charging transmitter 181 through the second DC converter 112, and the wireless charging transmitter 181 is connected to the control unit 100. The communication data line of the input terminal 131 is directly connected to the communication data line of the output terminal 161.

[0204] like Fig.14 The fourteenth embodiment differs from the first embodiment in that an energy storage device 151 is added.

[0205] The power output distribution device of the power supply circuit has four power output circuits, the first power output circuit is a direct connection between the input terminal 131 and the output terminal 1 161; the second power output circuit is a connection between the input terminal 1 131 and the output terminal 2 162 through the first DC converter 111; the third power output circuit is a connection between the input terminal 1 131 and the output terminal 3 163 through the second DC converter 112; the fourth power output circuit is a connection between the input terminal 1 131 and the internal charging circuit 133 of the energy storage device 151 to charge the energy storage device 151.

[0206] The sixth DC converter 165 inside the energy storage device 151 is connected to the input terminal 1 131. Like the power adapter 2 through the first input terminal 131 channel, the energy storage device 151 can output power to the output terminal 1 161, the output terminal 2 162, and the output terminal 3 163.

[0207] The communication data line of the input terminal 131 is directly connected to the communication data line of the output terminal 161.

[0208] like Fig.15 The fifteenth embodiment differs from the fourteenth embodiment in that a first switch unit 121 and a second switch unit 122 are added.

[0209] The device has four power output circuits, the first power output circuit is an input terminal 131 connected to the first switch unit 121 and then connected to the output terminal 1 161; the second power output circuit is an input terminal 131 connected to the output terminal 2 162 through the first DC converter 111; the third power output circuit is an input terminal 131 connected to the output terminal 3 163 through the second DC converter 112; the fourth output circuit is an input terminal 131 connected to the internal charging circuit 133 of the energy storage device 151 to charge the energy storage device 151.

[0210] The sixth DC converter 165 inside the energy storage device 151 is connected to the input terminal 1 131. Like the power adapter 2 through the first input terminal 131 channel, the energy storage device 151 can output power to the output terminal 1 161, the output terminal 2 162, and the output terminal 3 163.

[0211] The communication data line of the input terminal 131 is directly connected to the communication data line of the output terminal 161 through the second switch unit 122 .

[0212] The energy storage device 151 has a built-in control module and is connected to the control unit 100 .

[0213] like Fig.17 In the seventeenth embodiment, the control system of the device can be composed of a control unit 100 and multiple coprocessors 101, rather than a single controller. The advantage of this is that each coprocessor 101 is only responsible for simple control signals. For example, each USB port is controlled by a coprocessor 101, and each coprocessor 101 is responsible for one or more protocols (OPPO protocol, Huawei protocol, Apple protocol, etc.), making the software and circuit design simpler and more flexible.

[0214] In this embodiment, the control unit 100 is connected to the three coprocessors 101 , or the three coprocessors 101 are connected to each other and then connected to the control unit 100 .

[0215] like Fig.18 In the eighteenth embodiment, the device is further provided with a wireless module. The wireless module includes but is not limited to Zeebe, Wifi, Bluetooth, Lora, 5G, 4G, Huawei Star Flash, etc.

[0216] In this embodiment, the wireless module is an internal wireless circuit unit 102, and the internal wireless circuit unit 102 is connected to the control unit 100. The internal wireless circuit unit 102 is set in the device so that the device can be wirelessly connected to a mobile phone, a tablet and a computer. By installing corresponding programs (such as App) on them, the charging status can be clearly displayed, and the priority level of charging control and the remote intelligent control system can be adjusted through the Internet. Functions such as timed power off and timed charging can be realized.

[0217] like Fig.19 The difference between the nineteenth embodiment and the eighteenth embodiment is that the device also includes a microprocessor (including an AI control unit) 103, the microprocessor 103 is connected to the control unit 100, and the microprocessor 103 is used to connect to an external wireless circuit unit 104, so that the device can also be connected to the Internet.

[0218] like Fig. 20 In the twentieth embodiment, the control unit 100 is connected to the internal wireless circuit unit 102, and the internal wireless circuit unit 102 is connected to the external router 105 by wireless means, and then connected to the computer 106 or the Internet through the router 105, so as to control the device through the computer 106. The mobile phone 107 can also be directly connected through the internal wireless circuit unit 102 to control the device through the mobile phone.

[0219] like Fig.21 The first port 261 of the power adapter can be connected to the input terminal 1 131 of the device. The device has four output terminals, namely output terminal 1 161, output terminal 2 162, output terminal 3 163 and output terminal 5 164.

[0220] like Fig. 22 The present invention also provides a power output distribution method for a power supply circuit, comprising the following steps:

[0221] The control unit obtains input power through each input terminal;

[0222] The control unit redistributes the acquired input power according to the output power of each output terminal and outputs it to each output terminal;

[0223] The control unit detects whether the power circuit and data line of the input end and the output end are directly connected or connected through a control switch. If so, power is preferentially distributed to the output end that is directly connected to the power circuit and data line of the input end or connected through a control switch.

[0224] like Fig.23A , Fig. 23B and Fig.23C After S1 starts, the control unit detects whether the output terminal 1 161 or the output terminal 4 166 is connected to an electrical device. If the electrical device is connected, it enters S2. If the electrical device is not connected, it enters S3.

[0225] S2, the control unit closes the first switch unit 121, the second switch unit 122, and the third switch unit 123, and enters S4.

[0226] S4, whether the control unit preferably disconnects the first switch unit 121, the second switch unit 122 and the third switch unit 123 (via APP); if not, enter S5; if disconnected, enter S6;

[0227] S5, the control unit determines whether it is preferred (via APP) to disconnect the second switch unit 122. If not, the process proceeds to S7; if so, the process proceeds to S8.

[0228] S7, the power adapter directly communicates with the first port 331 of the power device through the first switch unit 121, the second switch unit 122, and the third switch unit 123 to obtain the best charging solution (such as the power adapter of the mobile phone manufacturer) or directly charges the fourth port 336 of the power device. This device gives priority to meeting the charging requirements of the first port 331 and the fourth port 336 of the power device (the priority can be changed through App control). The control unit calculates the efficiency η by subtracting the maximum power Pirem (after reserving the margin) remaining after the power Pom is used up by the first port 331 of the power device from the maximum power output by the power adapter at the current voltage V331 and V336. Enter S9.

[0229] η=Pom / Pi=V336*I336 / (V132*I 132)

[0230] Or η=Pom / Pi=V331*I331 / (V131*I131).

[0231] S9, the first DC converter 111 (reference Figure 1 ) or the third DC converter 113 (reference Figure 2 ) is equal to the voltage V331 (ignoring the losses of the second switch unit 121, the third switch unit 123 and the wire), and the charging voltage of the first port 331 of the power device changes with the load requirements. When it is detected that the output terminal 2 162 is connected to the second power device, after reading the various voltages and currents supported by the charging protocol of the second power device, the corresponding power Po1 can be obtained, and the control unit determines whether the power Pirem>Po1. If yes, the second port 332 of the power device outputs the power Po1, otherwise, the second port 332 of the power device outputs the power Pirem, and the efficiency η is calculated. Enter S10.

[0232] η=(Pom+Po1) / Pi=(V336*I336+V332*I332) / (V132*I 132) or η=(Pom+Po1) / Pi=(V331*I331+V332*I332) / (V131*I 131) (can be displayed on the terminal through APP).

[0233] S10, the control unit detects that the output terminal three 163 is also connected to the power consumer three, and after reading the various voltages and currents supported by the charging protocol of the power consumer three, the corresponding power Po2 can be obtained. The control unit determines whether the power Pirem>Po1+Po2, if so, the power consumer three port 333 outputs the power Po2, if not, the power consumer three port 333 outputs the power Pirem-Po1, or divides the power equally, or first satisfies the power Po2 to the power consumer three port 333, and the remaining power Pirem-Po2 is then given to the power consumer two port 332 (which can be determined according to the priority selection indication of the app), and the efficiency η is calculated.

[0234] η=(Pom+Po1+Po2) / Pi=(V336*I336+V332*I332+V333*I333) / (V132*I132) or η=(Pom+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131)(can be displayed on the terminal through APP)

[0235] Since the load is variable, the control unit can select the most efficient output mode to meet the requirements of each load according to the current situation. First, consider providing the maximum power to each load as much as possible (at the beginning of charging), and then consider efficiency when the power is equivalent. When the shell temperature is too high, choose high efficiency and reduce power. Enter S18.

[0236] S18, the control unit monitors whether the charging of the power-consuming device port 331 is completed (100%) or n%, if yes, then enter S3. If no, then end after completing all port tasks. (n%<1, can be set, such as 60%, 80%).

[0237] S8, when the device is connected to a port 331 of the power-consuming device, the device selects the highest voltage V331max from the charging scheme of the port 331 of the power-consuming device as much as possible to output power P331. Since the first switch unit (121) is closed, the voltage of the power adapter is equal to the voltage of the port V331 of the power-consuming device, so the input voltage from the power adapter is V331max, and its corresponding maximum input power is Pv331max. The control unit determines whether the power Pv331max*K>P331, if yes, the power output of the port 331 of the power-consuming device is P331, if no, the power output of the port 331 of the power-consuming device is Pv331max, and the margin is appropriately considered.

[0238] If the first port 331 of the power device is prioritized (or set by the App), when the output voltage of the first port 331 of the power device is V331, that is, the output voltage of the power adapter is V331, the corresponding maximum output power is Pv331. The controller unit determines whether the power Pv331*K>P331, if yes, the output power of the first port 331 of the power device is P331, if no, the output power of the first port 331 of the power device is Pv331*K (K is a margin coefficient less than 1), and calculates the efficiency η. Enter S11.

[0239] η=P331 / P131=V331*I331 / (V131*I131)(can be displayed on the terminal through APP).

[0240] S11, the control unit detects that the output terminal 2 162 is connected to the power device 2, and after reading various voltages and currents supported by the charging protocol of the power device 2, the corresponding power Po1 can be obtained. The control unit determines whether the power Pv331max*K-P331>Po1 (or Pv331*K-P331>Po1), if yes, the power device 2 port 332 outputs the power Po1, if no, the power device 2 port 332 outputs the power Pv331max*K-P331 (or Pv331*K-P331), and calculates the efficiency η. Enter S12.

[0241] η=P331 / P131=(V331*I331+V332*I332) / (V131*I131)(can be displayed on the terminal through APP)

[0242] S12, the control unit detects that the output terminal 3 163 is also connected to the power device 3, and after reading the various voltages and currents supported by the charging protocol of the power device 3, the corresponding power Po2 can be obtained. The control unit determines whether the power Pv331max-P331-Po1>Po2 or Pv331-P331-Po 1>Po2. If yes, the power device 3 port 333 outputs the power Po2, if not, the power device 3 port 333 outputs the power Pv331max-P331-Po1 or Pv331-P331-Po 1, or divides the power equally, or first satisfies the power Po2 to the power device 3 port 333, and the remaining power Pv331max-P331-Po2 or Pv331-P331-Po2 is then given to the power device 2 port 332 (which can be determined according to the app priority selection indication). Calculate the efficiency η.

[0243] η=(P331+Po1+Po2) / Pi=(V336*I336+V332*I332+V333*I333) / (V132*I132) or

[0244] η=(P331+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131)(can be displayed on the terminal through APP)

[0245] Since the load is variable, the control unit can select the most efficient output mode to meet the requirements of each load according to the current situation. First, consider providing the maximum power to each load as much as possible (at the beginning of charging), and then consider efficiency when the power is equivalent. When the shell temperature is too high, select high efficiency and reduce power. Enter S19.

[0246] S19, the control unit monitors whether the charging of the power-consuming device port 331 is completed (100%) or n%, if yes, then enter S3. If no, then end after completing all port tasks. (n%<1, can be set, such as 60%, 80%).

[0247] S3, the control unit disconnects the first switch unit 121, the second switch unit 122, and the third switch unit 123, and enters S6.

[0248] S6, the control unit determines whether there is a fifth DC converter 115, if not, it goes to S13, if yes, it goes to S17.

[0249] S13, the control unit first takes the maximum output voltage Vimax (or not) of the power adapter as the first DC converter 111 (reference Figure 1 ) or the third DC converter 113 (reference Figure 2 ) input voltage, at this time the power adapter can provide a maximum power of Pimax0. If it is first detected that the output terminal 2 162 is connected to the power device 2, the best solution for the power device 2 to support the protocol is first satisfied, and the charging voltage of the power device 2 port 332 changes with the load requirements. At this time, the output power corresponding to the voltage is Po1, and the control unit determines whether the power Pimax0*K (K is a margin coefficient less than 1)>Po1. If yes, the power device 2 port 332 outputs power Po1, otherwise, the power device 2 port 332 outputs power Pimax0*K. Enter S14.

[0250] In S13, a more cost-effective and simpler control solution can also be used (refer to Figure 1 and Figure 3 ): When there is no third DC converter 113 and the first DC converter 111 and the second DC converter 112 are Buck, the control unit requires the first port 261 of the power adapter to output a voltage V261=V131=V111i=V112i=Vomax+ΔV (about 1-2V, or not).

[0251] For example: V261 = 6-7V, 10-11V, 13-14V, 16-17V, 21-22V correspond to output 5V, 9V, 12V, 15V, 20V (PD3.0) respectively

[0252] V261=29-30V, 37-38V, 49-50V correspond to output 28V, 36V, 48V (PD3.1)

[0253] For example, if the load requires 15V, adjust the input V261 = 16-17V; if it requires 36V, adjust the input V261 = 37-38V...

[0254] ΔV is 1-2V at low power (wearable devices, mobile devices). ΔV will be much larger at high power.

[0255] S14, get efficiency η=Po1 / Pi=V332*I332 / (V131*I131) (all electronic information including temperature and efficiency η can be displayed on the App terminal), gradually reduce (change) the power adapter voltage Vi, get the input voltage and corresponding efficiency. After a preliminary and rapid scan of all Vi voltages, the voltage corresponding to the highest efficiency is the input voltage. Dynamically monitor the output of the second port 332 of the electrical equipment and select the input voltage according to the efficiency. At this time, the maximum output power of the power adapter is Pimax. Enter S15.

[0256] S15, the control unit detects that the output terminal 3 163 is connected to the power device 3, and first satisfies the best solution of the power device 3 supporting the protocol, and the charging voltage of the power device 3 port 333 changes with the load. At this time, the power corresponding to the voltage is Po2, and the control unit determines whether the power Pimax*K (K is a margin coefficient less than 1)>Po1+Po2. If yes, the power device 3 port 333 outputs power Po2, otherwise, the power device 3 port 333 outputs power Pimax*K-Po1, or divides the power equally, or first satisfies the power Po2 to the power device 3 port 333, and the remaining power Pimax*K-Po2 is then given to the power device 2 port 332 (which can be determined according to the app priority selection indication). Enter S16.

[0257] S16, after scanning all the Vi voltages, the voltage corresponding to the highest efficiency is obtained as the input voltage Vi, and the efficiency η=(Po1+Po2) / Pi=(V332*I332+V333*I333) / (V131*I131) is obtained (all electronic information including temperature and efficiency η can be displayed on the App terminal), and the voltage Vi is gradually reduced to obtain the corresponding output parameters, and the input voltage and the corresponding efficiency are recorded. The voltage corresponding to the highest efficiency is selected as the input voltage. Monitor the output of the second port 332 of the electrical equipment and the third port 333 of the electrical equipment, dynamically allocate power (App priority) and select the input voltage according to the efficiency.

[0258] The control unit can select the most efficient output mode to meet the requirements of each load according to the current situation. First, consider providing the maximum power to each load (at the beginning of charging), and then consider efficiency when the power is equivalent. When the shell temperature is too high, choose high efficiency and reduce power.

[0259] After all port tasks are completed, end.

[0260] S17, the control unit first takes the maximum output voltage Vimax (or not) of the power adapter as the first DC converter 111 ( Figure 1 ) or the third DC converter 113 ( Figure 2 ) input voltage, at this time the maximum input power is Pimax0. If it is first detected that the output terminal 161 is connected to the power device 1, the best solution for the power device 1 port 331 to support the protocol is first satisfied, and the charging voltage of the power device 1 port 331 changes with the load requirements. At this time, the power corresponding to the voltage is Pom, and the control unit determines whether the power Pimax0*K>Pom, if yes, the power device 1 port 331 outputs the power Pom, if not, the power device 2 port 332 outputs the power Pimax0*K; enter S20.

[0261] S17 has a cost-effective and simple control solution (reference Fig.12 ): When the first DC converter 111, the second DC converter 112, and the third DC converter 115 are Buck, the control unit 100 requires the output voltage V261 of the first port 261 of the power adapter 2 to be equal to Vimax; in this mode, V261=Vimax remains unchanged throughout the entire process (S20, S21, S22, S23), and the control is simple.

[0262] Or the control unit 100 requires the output voltage of the first port 261 of the power adapter 2 to be V261=V131=V111i=V112i=V115i=Vomax+ΔV (about 1-2V, or not).

[0263] V111i, V112i, and V115i are input voltages of the first DC converter 111, the second DC converter 112, and the second DC converter 115, respectively.

[0264] For example: V261=6-7V, 10-11V, 13-14V, 16-17V, 21-22V correspond to outputs of 5V, 9V, 12V, 15V, 20V (PD3.0) respectively.

[0265] V261=29-30V, 37-38V, 9-50V correspond to output 28V, 36V, 48V (PD3.1)

[0266] For example, if the load requires 15V, adjust the input V261=16-17V; if it requires 36V, adjust the input V261=37-38V.

[0267] S20, get the efficiency η=Pom / Pi=V331*I331 / (V131*I 131), gradually reduce the voltage Vi of the power adapter, get the input voltage and the corresponding efficiency. After preliminary and rapid scanning of all Vi voltages, get the voltage corresponding to the highest efficiency as the input voltage. Dynamically monitor the output of the first port 331 of the electrical equipment and select the input voltage according to the efficiency. At this time, the maximum output power of the power adapter is Pimax. Enter S21.

[0268] S21, the control unit detects that the output terminal 2 162 is connected to the power device 2, and firstly satisfies the best solution of the power device 2 supporting the protocol, and the charging voltage of the power device 2 port 332 changes with the load. At this time, the power corresponding to the voltage is Po1, and the control unit determines whether the power Pimax*K>Pom+Po1, if yes, the power device 2 port 332 outputs the power Po1, otherwise, the power device 2 port 332 outputs the power Pimax*K-Pom. Enter S22.

[0269] S22, the control unit detects that the output terminal 3 163 is connected to the power device 3, and first satisfies the best solution of the power device 3 supporting the protocol, and the charging voltage of the power device 3 port 333 changes with the load. At this time, the power corresponding to the voltage is Po2, and the control unit determines whether the power Pimax*K>Pom+Po1+Po2, if yes, the power device 3 port 333 outputs the power Po2, if not, the power device 3 port 333 outputs the power Pimax*K-Pom-Po1, or divides the power equally, or satisfies the power Po2 to the power device 3 port 333 first, and the remaining power Pimax*K-Pom-Po2 is then given to the power device 2 port 332. Enter S23.

[0270] S23, rescan all Vi voltages, obtain the voltage corresponding to the highest efficiency as the input voltage, and obtain the efficiency η=(Pom+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131), monitor the output of port 1 331, port 2 332, and port 333 of the electrical equipment, dynamically allocate power and select the input voltage according to the efficiency.

[0271] After all port tasks are completed, end.

[0272] During the whole process, the control unit can control the power adapter 2 to select and meet the following requirements according to the priority level:

[0273] (1) Satisfying all energy requirements of output terminal 1 161, output terminal 2 162, and output terminal 3 163, with high efficiency;

[0274] (2) not satisfying the full energy of output terminal 1 161, output terminal 2 162, and output terminal 3 163, and providing sufficient energy;

[0275] (3) Not satisfying all the energy of output terminal 1 161, output terminal 2 162, and output terminal 3 163, providing the same energy with high efficiency.

[0276] In the example, the order of describing output terminal 1 161, output terminal 2 162, and output terminal 3 163 is only used for description and is changeable.

[0277] like Fig.23C , applicable Fig.16 S61, after starting, detect that the output terminal is connected to an electrical device (if it is output terminal 161), and enter S62.

[0278] S62, the control unit requires the power adapter to charge the output terminal 161 at an extremely fast speed, and completes the extremely fast charging mode, and enters S63.
