Description

A power output distribution device and method for a power supply circuit Technical Field

[0001] This invention relates to the field of portable power supply technology, and more specifically to a power output distribution device and method for a power supply circuit. Background Technology

[0002] With the explosive growth of smartphones and laptops, and the rapid development of new energy electric vehicles, the photovoltaic industry, and energy storage equipment, electronic power modules and portable power bank products are becoming increasingly common. These products are becoming increasingly miniaturized. Lithium batteries are widely used in mobile devices, and each manufacturer designs specific charging schemes based on the characteristics of the selected batteries to achieve the fastest and safest charging. However, due to the flammability and explosiveness of lithium batteries, each manufacturer uses its own encrypted proprietary protocol (generally not publicly disclosed, except in authorized cases) for safety reasons, resulting in poor compatibility. To make mobile devices more convenient and faster to use, charging speeds are increasing, and power requirements are rising. How to redistribute and expand the applications of various adapters, ensuring compatibility, practicality, and convenient monitoring, has become a new challenge. The ability to expand compatibility with other output ports without changing the original performance of the adapter is a problem that urgently needs to be solved.

[0003] In practice, high-power output devices have limited application scenarios. For example, a mobile phone charger that is nominally rated at 240W may only use its peak power of 213W for a few seconds during actual use, with the vast majority of the time it only uses 20-40W of power, which is extremely wasteful. After charging the phone, a large portion of the energy could be used to charge other devices, but this is hampered by the limited output port.

[0004] For example, a mobile phone charger that claims to be 150W only outputs a maximum voltage of 11V, making it unusable for many devices, including notebooks. Furthermore, USB charging protocols evolve rapidly with product upgrades; PD3.0 adapters can only support a maximum output voltage of 20V, and therefore cannot provide functionality for devices that support PD3.1.

[0005] When mobile phone manufacturers launch new products (increasing battery capacity and shortening charging time), they develop the optimal charging solution based on the characteristics of the selected battery (i.e., fast and safe). They don't consider compatibility with other brands of charging devices and often only include a single charging port. If you need to charge multiple devices simultaneously, you must buy multiple charging adapters or more expensive multi-port adapters (these adapters can charge the phone, but they may not be the optimal charging solution; for example, charging time is slower, and charging safety is not as good as the original adapter), and compatibility and expandability are limited.

[0006] Similarly, electric vehicles also use lithium batteries. For fast and safe charging, they initially charge at extremely high speeds. However, when the battery temperature reaches a safety warning point (within a very short time), the charging power is rapidly reduced. This method significantly improves the power utilization rate of charging stations and can multiply their capacity.

[0007] Competition is fierce across all industries, and the power supply industry is no exception. Take chargers and power banks, for example; one day you release a two-port charger, the next day a three-port one, and the day after that a four-port one. Each update requires a complete redesign of the product's structure and circuitry. Because these are mandatory certification products, each one must obtain certifications (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, etc.). This practice leads to a massive waste of manpower, materials, and energy in design and production.

[0008] Due to the limited functionality and practicality of existing products, coupled with the rapid updates and increasingly demanding functional requirements of charging equipment, it is often necessary to repurchase expensive multi-port products with newer specifications, such as PD3.1. The circuitry must handle high-voltage AC mains power through EMI circuitry, AC-DC control circuitry, high-voltage gallium nitride switches, isolation transformers, DC-DC converters, and port protocol circuitry. Furthermore, the cost of various certifications, which consume considerable resources, results in exorbitant expenses. Summary of the Invention

[0090] As shown in Figure 1, the power output distribution device (hereinafter referred to as "this device") 1 of the present invention includes a control unit (including an AI control unit) 100, input terminals, and output terminals. There is at least one input terminal, each connected to the control unit 100. Each input terminal is used to connect to a power supply device or a power adapter, and is used to acquire power information (including voltage, current, power, maximum temperature, etc.) from the power supply device or power adapter. There is at least one output terminal, connected to the control unit. Each output terminal is used to connect to an electrical device, and is used to acquire power information (including voltage, current, power, maximum temperature, etc.) from the electrical device.

[0091] In this invention, power circuits and data lines having at least one pair of input terminals and output terminals are directly connected or connected through a control switch, or power circuits having at least one pair of input terminals and output terminals are directly connected or connected through a control switch.

[0092] The control unit 100 obtains the input power through the input terminal, and then redistributes it to each output terminal based on the output power of each output terminal. At the same time, it adjusts the optimal input voltage and current according to the output voltage and current requirements.

[0093] In situations where dedicated power supply devices or power adapters can only charge a single device, have a small output voltage range (small voltage, large current), limited application scenarios, or have high-power power supply devices with extremely short high-power charging times, this device, when used in combination with a power supply device or power adapter, expands the practicality and application range of the original product by adjusting the voltage range, expanding the output ports, and intelligently and controllably distributing the output power, without changing the performance or compatibility of the original power supply device or power adapter.

[0094] For example, a 240W charger, in actual use, only delivers a peak charging time of 213W for a few seconds, with the majority of the time only 20-40W of charging power (power utilization rate less than 20%). A 150W charger's maximum output voltage is only 11V (not even suitable for laptops). These two chargers are a waste. Combining these two chargers with this device does not change the previous fast charging performance and safety, and can still meet the needs of most current mobile terminal devices, charging multiple devices simultaneously. This device completes the conversion through a DC-DC converter combination, which is extremely low-cost, easy to update and upgrade, very easy to certify, and can be controlled by AI (via a wireless module, OTA updates are possible).

[0095] As shown in Figure 1, in the first embodiment, there is one input terminal, namely input terminal 131, and three output terminals, namely output terminal 161, output terminal 2 162 and output terminal 3 163.

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

[0097] Simultaneously, the communication data line of input terminal 131 is directly connected to the communication data line of output terminal 161. This means that the power signal and data signal of input terminal 131 are directly connected to output terminal 161, equivalent to the first port 261 of power adapter 2 being directly connected to port 331 of the electrical device. Clearly, after connecting to device 1, power adapter 2 retains all the performance characteristics and load-carrying capacity of the original power adapter (with the same compatibility and safety), enabling the expansion of new functions without altering the original performance of the power adapter.

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

[0099] In this embodiment, we will explain the two cases in detail: when the power supply is connected through the output terminal 161 and when the power supply is not connected.

[0100] When output terminal 161 is connected to the power supply:

[0101] The control unit 100 obtains the power information (including maximum voltage, maximum current, and rated power) that the power adapter 2 can provide to input terminal 131 through input terminal 131. It obtains the information of the connected electrical devices (including the required output voltage and current) through output terminals 161, 162, and 163. The output of output terminal 161 is entirely determined by the protocol between the power adapter 2 and the electrical device's port 331, and is not controlled by the control unit 100; that is, it prioritizes meeting the requirements of the charging device connected to output terminal 161. The control unit 100 analyzes and calculates the maximum power P131imax@V331 that input terminal 131 can provide under the current voltage, subtracts the power output Pom = V331*I331 from output terminal 161, and obtains the remaining power Pirem after removing output terminal 161. This remaining power Pirem is then distributed to the electrical devices connected to output terminals 162 and 163 by controlling the first DC-DC converter 111 and the second DC-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 efficiency calculation of the control unit should be as follows: Ignoring losses, V161 = V331, V162 = V332, V163 = V333. All examples use V331, V332, V333, I331, I332, and I333 to represent V161, V162, V163, I161, I162, and I163 respectively, which will not be elaborated further.

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

[0105] The following are the output specifications of a certain 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 power adapter 2 will change with the voltage V331 (V331=V131) (ignoring losses, some margin should be reserved for actual applications).

[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 about 20-40W most of the time.

[0113] When the power adapter 2 charges the device at port 331 with 40W, the voltage V331 = 20V. At this time, the power that can be provided to output port 162 and output port 163 is 240W - 40W = 200W (ignoring losses, some margin should be left). There is still 80% of the energy to charge other devices (this embodiment gives three output ports, but it can also have four, five, six, etc.).

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

[0115] By using Boost or Buck-Boost topology circuits for the first DC-DC converter 111 and the second DC-DC converter 112, the voltages at output terminals 162 and 163 can be changed to 28V, 36V, and 48V, respectively.

[0116] When used in conjunction with this device 1, the power adapter 2 can achieve compatibility with PD3.1 products, thus expanding the product's practicality and application range.

[0117] When output terminal 161 is not connected to any electrical equipment:

[0118] The control unit 100 obtains the power information (including maximum voltage, maximum current, and rated power) that the power adapter 2 can provide to the input terminal 131 through input terminal 131. It obtains the information of the connected electrical equipment (including the required output voltage and current) through output terminals 162 and 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) is obtained. The voltage adapter provides different amounts of energy (load capacity) at different output voltages. The control unit 100 selects components according to priority to meet the following requirements:

[0121] (1) It meets all the energy requirements of output terminal 162 and output terminal 163 and has high efficiency;

[0122] (2) The output terminals 162 and 163 do not provide enough energy for all of their outputs;

[0123] (3) It does not satisfy the requirement that the output terminals 162 and 163 provide the same amount of energy and have high efficiency.

[0124] The control unit 100 first takes the maximum output voltage Vimax (or not) of the power adapter 2 as the input voltage of the first DC-DC converter 111 or the second DC-DC converter 112. At this time, the maximum power of the first port 261 of the power adapter 2 is P261@20V (as in the parameters of the 240W power adapter mentioned earlier, the power at a maximum voltage of 20V is P261@20V=240W). The control unit 100 adjusts the output of the first DC-DC converter 111 and the second DC-DC converter 112 to supply power to the electrical equipment connected to the second output terminal 162 and the third output terminal 163. The efficiency η is obtained as follows: η=(Po1+Po2) / Pi=(V332*I332+V333*I333) / (V131*I131).

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

[0126] The control unit 100 analyzes and calculates the maximum power that input terminal 131 can provide under the current voltage as P131imax@V331. The control unit 100 distributes the power to the electrical equipment connected to output terminal 162 and output terminal 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. It 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 to distribute power to the electrical equipment connected to the output terminal 162 and the output terminal 163 through the control unit 100. The control is relatively complex.

[0128] Another cost-effective and simple-to-control method is to use Buck converters 111 and 112.

[0129] When output terminal 161 is first connected to the device, during high-power charging (e.g., voltage V331 = 20V, at the start of charging or when connected to a laptop), if the voltage difference ΔV between the first DC-DC converter 111 and the second DC-DC converter 112 is approximately 1.5V, the output voltage range of output terminals 162 and 163 is 0-18.5V, which has a wide range of applications. When the phone is almost fully charged, the voltage drops to V331 = 5V, and the output voltage of output terminals 162 and 163 is 0-3.5V, which has fewer applications (but Example 3 can solve this problem).

[0130] When no electrical equipment is connected to output terminal 161, 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 required output voltage and current) of the connected electrical equipment through output terminal 162 and output terminal 163. The control unit 100 requires that the voltage V261 at the first port 261 of the power adapter 2 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-DC converter 111 or the second DC-DC converter 112. The efficiency η can be obtained as (Po1 + Po2) / Pi = (V332 * I332 + V333 * I333) / (V131 * I131).

[0132] The power adapter 2 provides different amounts of energy (load capacity) when outputting different voltages. The control unit 100 selects the appropriate option based on priority, meeting the following requirements:

[0133] (1) It meets all the energy requirements of output terminal 162 and output terminal 163 and has high efficiency;

[0134] (2) The output terminals 162 and 163 do not provide enough energy for all of their outputs;

[0135] (3) It does not satisfy the requirement that the output terminals 162 and 163 provide the same amount of 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. It 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 to distribute power to the electrical equipment connected to the output terminal 162 and the output terminal 163 through the control unit 100. The control is relatively complex.

[0137] Alternatively, the voltage V261 = V261max can be directly taken. Typically, this is when power adapter 2 can output the highest power, such as the 240W power adapter mentioned earlier, with power P261 = 240W@20V. The control unit 100 controls the first DC-DC converter 111 and the second DC-DC converter 112 to distribute the corresponding voltage and current to the electrical devices connected to output terminals 162 and 163. If a power adapter with an output voltage higher than the PD3.0 or PD3.1 voltage ΔV is connected, this device can adjust the input voltage via protocol to supply power to PD3.0 and PD3.1 devices.

[0138] For example, the control unit 100 adjusts the voltage V261 to 21-22V via the protocol to ensure that after passing through Buck, the voltage V332 is 20V or V333 is 20V, thus satisfying PD3.0.

[0139] Control unit 100 adjusts voltage V261 to 29-30V via protocol to ensure that after passing through Buck, voltage V332 = 28V or V333 = 28V, satisfying PD3.1;

[0140] Control unit 100 adjusts voltage V261 to 37-38V via protocol to ensure that after passing through Buck, voltage V332 = 36V or V333 = 36V, satisfying PD3.1;

[0141] Control unit 100 adjusts voltage V261 to 49-50V via protocol to ensure that after passing through Buck, voltage V332 = 48V or V333 = 48V, satisfying PD3.1.

[0142] In this method, the first DC converter 111 and the second DC converter 112 are Buck converters, which are low in cost, cost-effective, and easy to control. However, the power adapter of PD3.0 cannot meet the requirements for upgrading to PD3.1 when used with this device (this problem can be solved in Embodiment 2).

[0143] In the first embodiment, output terminal 2 162 is connected to port 332 of the second power device, and output terminal 3 163 is connected to port 333 of the third power device.

[0144] As shown in Figure 2, 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 application scenarios can be realized, which can solve the shortcoming mentioned in the first embodiment that the PD3.0 power adapter cannot meet the charging requirements of PD3.1 devices when used with this device 1.

[0145] When the first DC-DC converter 111 and the second DC-DC converter 112 use Buck converters, it is easy to add a third DC-DC converter 113 as a boost converter or a buck-boost converter.

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

[0147] The first DC-DC converter 111 and the second DC-DC converter 112 use Buck converters (this circuit is low-cost and simple to 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 at port 331 of the device will drop to V331 = 5V. When the mobile phone is almost fully charged, if the voltage difference ΔV between the first DC converter 111 and the second DC converter 112 is approximately 1.5V, the output voltage at output port 162 and output port 163 will be 0-3.5V, which has limited application scenarios (refer to the first embodiment).

[0149] If the control unit 100 detects that port 331 of the electrical device is fully charged, it disconnects the first switch unit 121 and the second switch unit 122, and resets the voltage V261 of the first port 261 of the power adapter 2, such as V261max, or the voltage at which the power adapter 2 outputs the maximum power. If the power adapter 2 connected to output port 161 is not the original power adapter 2 of the electrical device, or if the original power adapter 2 of the electrical device is connected but it is necessary to prioritize charging the electrical devices connected to output port 2 162 and output port 3 163 (which can be set by the App for devices with wireless modules), the method of setting V261 = V261max can be used.

[0150] As shown in Figure 4, 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 the first embodiment, thus changing to the second embodiment.

[0151] As shown in Figure 5, 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, both of which are DC power interfaces.

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

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

[0154] Existing interfaces with both data and power signals (such as USB-A and USB-C interfaces) can only handle a very small current, typically only 5-6A at most. By using existing integrated interfaces with both data and power signals and extracting data information as a protocol communication channel, DC interfaces can handle larger currents.

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

[0156] As shown in Figure 6, the difference between the sixth embodiment and the fifth embodiment is that a third DC converter 113 is added between the first input terminal 131, the second input terminal 132 and the first DC converter 111 and the second DC converter 112. Different application scenarios can be realized by changing the power conversion topology combination between them.

[0157] The wireless module has been added to Figures 7, 8 and 9 to facilitate intelligent control. This device is connected to the terminal and controlled via an APP.

[0158] As shown in Figure 7, the difference between the seventh embodiment and the sixth embodiment is that the device is equipped with a wireless module for easy intelligent control. Wireless modules include, but are not limited to, Zeebe, Wi-Fi, Bluetooth, LoRa, 4G, 5G, 6G, and Huawei's StarScan, etc.

[0159] In this embodiment, an internal wireless circuit unit 102 is provided, which is connected to the control unit 100. The internal wireless circuit unit 102 (refer to Figure 18; it can also be connected to a USB interface via an external wireless circuit unit 104) allows the device to wirelessly connect to mobile phones, tablets, and computers. Installing corresponding programs (such as Apps) on these devices can clearly display the charging status and allow for adjusting the charging priority and remote intelligent control via the internet. This enables functions such as remote monitoring of charging status, control of the switch, power distribution, timed power-off, and timed charging.

[0160] As shown in Figure 8, the difference between the eighth embodiment and the fifth embodiment is that the eighth embodiment adds a first switch unit 121 (power switch), a second switch unit 122 (a set of data switches), a third switch unit 123 (power switch) and an internal wireless circuit unit 102.

[0161] Only one power interface can be used at a time, either input terminal 131 or input terminal 132. (This is optional; the diagram does not provide an example.)

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

[0163] The first type: Input terminal 131 outputs power through a three-way power output circuit. The first power output circuit connects input terminal 131 to the first switch unit 121 and then to output terminal 161. The second power output circuit connects input terminal 131 to output terminal 162 through the first DC-DC converter 111. The third power output circuit connects input terminal 131 to output terminal 163 through the second DC-DC converter 112.

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

[0165] The above describes the general power control methods for USB, which involve relatively low current, voltage, and power.

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

[0167] At this time, the first power output can output high power, but since there is no control signal, the power parameters cannot be controlled.

[0168] The third method: Input terminal 2 132 outputs power via a three-way power output circuit. The first power output circuit connects input terminal 2 132 to the third switch unit 123 and then to output terminal 4 166. The second power output circuit connects input terminal 2 132 to the first DC-DC converter 111 and then to output terminal 2 162. The third power output circuit connects input terminal 2 132 to the second DC-DC converter 112 and then to output terminal 3 163. The communication data line of input terminal 1 131 is connected to the communication data line of output terminal 1 161 via the second switch unit 122.

[0169] At this point, the high-current, high-voltage, and high-power transmission has a set of input terminals, namely input terminal 131 as the first data signal input terminal and input terminal 132 as the first high-power input terminal. It also has a set of output terminals, namely output terminal 161 as the first data signal output terminal and output terminal 166 as the first high-power output terminal.

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

[0171] In Figure 8, the power adapter 2 contains both a set of data ports (i.e., the first port 261) and a high-power power interface (i.e., the third port 263).

[0172] Electrical device 3 also contains a set of data ports (i.e., electrical device port 331) and a high-power power interface (i.e., electrical device port 336).

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

[0174] As shown in Figure 9, the difference between the ninth embodiment and the eighth 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 and the second DC converter 112.

[0175] Similarly, only one connection can be used at a time for the power interfaces of input terminal 131 and input terminal 132 (this is not always the case, as not illustrated in the diagram), or input terminal 131 can be used as a data information interface and input terminal 132 can be used as a high-power power interface.

[0176] As shown in Figure 10, the difference between the tenth embodiment and the third embodiment is that a fifth DC-DC converter 115 is added, and the fifth DC-DC converter 115 is connected in parallel with the first switching unit 121. That is, the first power output circuit is connected to the output terminal 161 through the parallel circuit of the first switching unit 121 and the fifth DC-DC converter 115.

[0177] When output terminal 161 is not connected to the original power adapter 2, or although it is connected to the original power adapter 2, it is necessary to prioritize charging output terminal 162 and output terminal 163:

[0178] When both the first switch unit 121 and the second switch unit 122 are turned on, the circuit structure becomes as shown in Figure 1.

[0179] When both the first switch unit 121 and the second switch unit 122 are disconnected, the circuit structure becomes as shown in Figure 11 (i.e., the eleventh embodiment).

[0180] If the first DC converter (111), the second DC converter (112), and the fifth DC converter (115) are Buck, the circuit structure becomes as shown in Figure 12 (i.e., 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 required output voltage and current) of the connected electrical equipment through output terminal 161, output terminal 162, and output terminal 163. The control unit 100 requires that the voltage V261 of the first port 261 of the power adapter 2 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 and the second DC converter 112, and the efficiency η can be obtained as follows: η = (Pom + Po1 + Po2) / Pi = (V331 * I331 / V332 * I332 + V333 * I333) / (V131 * I131).

[0183] Power adapter 2 provides different amounts of energy (load capacity) at different output voltages. Power adapter 2 should be selected according to priority to meet the following requirements:

[0184] (1) It meets all the energy requirements of output terminal 161, output terminal 2 162, and output terminal 3 163, and has high efficiency;

[0185] (2) The output terminals 161, 162, and 163 do not provide enough energy;

[0186] (3) It does not satisfy the requirement that all the energy provided by output terminal 161, output terminal 262, and output terminal 363 is the same and has high efficiency.

[0187] The tenth embodiment has one more fifth DC-DC converter 115 than the third embodiment. By disconnecting the first switching unit 121, all three output ports can be charged simultaneously, and the input voltages V131 (V111 = V112 = V115) of the first DC-DC converter 111, the second DC-DC converter 112, and the fifth DC-DC converter 115 can be equalized.

[0188] =V131)≠V331 (unlike in the third embodiment, where the voltage V131=V331 when the output terminal 161 is connected to the electrical device, it is constrained by the port 331 of the electrical device). It can also monitor the efficiency η in real time, intelligently select input requirements, and control the first DC converter 111, the second DC converter 112, and the fifth DC converter 115 to distribute voltage and current to the electrical devices connected to the output terminal 161, the output terminal 2 162, and the output terminal 3 163, and has 3 independent output ports, one more than in the third embodiment.

[0189] The control unit 100 directly sets the voltage V261 = V261max (usually at this voltage, the power adapter can output a larger power), such as the 240W power adapter mentioned earlier, with power P261 = 240W@20V. The control unit 100 distributes voltage and current to the electrical equipment connected to output terminals 161, 162, and 163 by controlling the fifth DC-DC converter 115, the first DC-DC converter 111, and the second DC-DC converter 112.

[0190] This method is low-cost, cost-effective, and easy to control. However, the PD3.0 power adapter, when used with this device, cannot meet the requirements for upgrading to PD3.1 (this problem can be solved by adding a third DC-DC converter 113, as in the second embodiment). Buck converters step down, resulting in a lower output voltage. However, this device can adjust the voltage of power adapters with output voltages higher than the PD3.0 device's output voltage via protocol, thus enabling power supply to PD3.1 devices. If a power adapter with an output voltage ΔV higher than the PD3.0 or PD3.1 voltage is connected, this device, when used with this device, can adjust the input voltage via protocol to power both PD3.0 and PD3.1 devices.

[0191] For example, the control unit 100 adjusts the voltage V261 = 21-22V through the protocol to ensure that the voltage V332 = 20V or V333 = 20V after passing through Buck, thus satisfying PD3.0;

[0192] Control unit 100 adjusts voltage V261 = 29-30V via protocol to ensure that voltage V332 = 28V or V333 = 28V after passing through Buck, thus satisfying PD3.1;

[0193] Control unit 100 adjusts voltage V261 to 37-38V via protocol to ensure that voltage V332 after Buck is 36V or V333 is 36V, thus satisfying PD3.1;

[0194] Control unit 100 adjusts V261 = 49-50V via protocol to ensure that the voltage after Buck is V332 = 48V or V333 = 48V, thus satisfying PD3.1.

[0195] The first switch unit 121 and the second switch unit 122 can be mechanical linkage switches (or electronic switches). When the electrical device connected to output terminal 161 uses the original power adapter 2, the first switch unit 121 and the second switch unit 122 are closed, prioritizing the optimal charging scheme for output terminal 161. All three output terminals charge simultaneously. When the electrical device connected to 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 operate independently. Output terminal 161 is compatible with the original power adapter and has an additional independently operating output port (refer to the first to ninth embodiments).

[0196] As shown in Figure 16, the difference between the sixteenth embodiment and the tenth embodiment is that a fifth switching unit 125 is added, which is connected in parallel with the first DC-DC converter 111. A seventh switching unit 127 is added, which is connected in parallel with the second DC-DC converter 112. That is, the second power output circuit connects input terminal 131 to output terminal 162 via the parallel circuit of the fifth switching unit 125 and the first DC-DC converter 111. The third power output circuit connects input terminal 131 to output terminal 163 via the parallel circuit of the seventh switching unit 127 and the second DC-DC converter 112.

[0197] Simultaneously, a fourth switch unit 124 and a sixth switch unit 126 were added, allowing the communication data line of input terminal 131 to be directly connected to the communication data line of output terminal 161 via the second switch unit 122. The communication data line of input terminal 131 is directly connected to the communication data line of output terminal 162 via the fourth switch unit 124. The communication data line of input terminal 131 is directly connected to the communication data line of output terminal 163 via the sixth switch unit 126.

[0198] The advantages of this are: the output ports can be directly connected to the input ports, and all the performance of the original adapter can be obtained. Furthermore, it can simultaneously meet the high-speed and safe output requirements of all ports.

[0199] As with the 240W adapter mentioned earlier, three phones are connected simultaneously. The control unit directly connects the first phone's port for input (data and power simultaneously), at which point the adapter charges it at a high power of 213W. Simultaneously, the second and third phones can share the remaining 27W power (for a very short time). After the first phone completes its 213W high-power fast charging, its pass-through mode is disconnected, and the second phone is switched to pass-through mode. The second phone then charges at a high power of 213W, while the remaining 27W power is shared with the first and third phones. The second phone will soon complete its 213W high-power fast charging as well, then its pass-through mode is disconnected again, and the third phone is switched to pass-through mode. Finally, all three phones are charged at 40W -> 20W (with 120W-180W remaining to power all three phones). All three ports can simultaneously provide fast and safe charging services. It can be seen that this 240W adapter can optimally charge six phones simultaneously.

[0200] Clearly, in the sixteenth embodiment, all output ports of this device can be directly connected to the original power adapter output ports (power and data interfaces) via control, resulting in a much higher utilization rate of the original adapter compared to the tenth embodiment. Of course, some output ports of this device can also be directly connected to the original adapter output ports (not illustrated).

[0201] As shown in Figure 13, the thirteenth embodiment differs from the first embodiment in that it has two output terminals, namely output terminal one 161 and output terminal two 162, and adds a wireless charging transmitter 181.

[0202] This device has three power output circuits. The first power output circuit connects input terminal 131 directly to output terminal 161. The second power output circuit connects input terminal 131 to output terminal 162 via a first DC-DC converter 111. The third power output circuit connects input terminal 131 to a wireless charging transmitter 181 via a second DC-DC converter 112. The wireless charging transmitter 181 is connected to the control unit 100. The communication data lines of input terminal 131 and output terminal 161 are directly connected.

[0203] As shown in Figure 14, the fourteenth embodiment differs from the first embodiment in that an energy storage device 151 is added.

[0204] The power output distribution device of this power circuit has four power output circuits. The first power output circuit is directly connected to the input terminal 131 and the output terminal 161. The second power output circuit is connected to the input terminal 131 and the output terminal 162 through the first DC-DC converter 111. The third power output circuit is connected to the input terminal 131 and the output terminal 163 through the second DC-DC converter 112. The fourth power output circuit is connected to the internal charging circuit 133 of the energy storage device 151 through the input terminal 131 to charge the energy storage device 151.

[0205] The sixth DC-DC converter 165 inside the energy storage device 151 is connected to input terminal 131. Similar to the power adapter 2 via the first input terminal 131, the energy storage device 151 can supply power to output terminals 161, 162, and 163.

[0206] The communication data line of input terminal 131 is directly connected to the communication data line of output terminal 161.

[0207] As shown in Figure 15, the fifteenth embodiment differs from the fourteenth embodiment in that a first switch unit 121 and a second switch unit 122 are added.

[0208] This device has four power output circuits. The first power output circuit is connected to the first switch unit 121 via input terminal 131 and then to output terminal 161. The second power output circuit is connected to the second output terminal 162 via the first DC-DC converter 111 via input terminal 131. The third power output circuit is connected to the third output terminal 163 via the second DC-DC converter 112 via input terminal 131. The fourth output circuit is connected to the internal charging circuit 133 of the energy storage device 151 via input terminal 131 to charge the energy storage device 151.

[0209] The sixth DC-DC converter 165 inside the energy storage device 151 is connected to input terminal 131. Similar to the power adapter 2 via the first input terminal 131, the energy storage device 151 can supply power to output terminals 161, 162, and 163.

[0210] The communication data line of input terminal 131 is directly connected to the communication data line of output terminal 161 through the second switch unit 122.

[0211] The energy storage device 151 has a built-in control module and is connected to the control unit 100.

[0212] As shown in Figure 17, in the seventeenth embodiment, the control system of this device can consist of a control unit 100 and multiple coprocessors 101, instead of a single controller. The advantage of this is that each coprocessor 101 only needs to handle simple control signals. For example, each USB port can be controlled by one coprocessor 101, and each coprocessor 101 can handle one or more protocols (OPPO protocol, Huawei protocol, Apple protocol, etc.), making software and circuit design simpler and more flexible.

[0213] In this embodiment, the control unit 100 is connected to three coprocessors 101, or the three coprocessors 101 are interconnected before being connected to the control unit 100.

[0214] As shown in Figure 18, in the eighteenth embodiment, the device further includes a wireless module. The wireless module includes, but is not limited to, Zeebe, Wi-Fi, Bluetooth, LoRa, 5G, 4G, Huawei StarFlash, etc.

[0215] In this embodiment, the wireless module is an internal wireless circuit unit 102, which is connected to the control unit 100. The internal wireless circuit unit 102 within this device allows it to wirelessly connect to mobile phones, tablets, and computers. Installing corresponding programs (such as apps) on these devices clearly displays the charging status, and users can adjust the charging priority and remotely control the intelligent system via the internet. Functions such as timed power-off and timed charging are also possible.

[0216] As shown in Figure 19, the difference between the nineteenth embodiment and the eighteenth embodiment is that the device further includes a microprocessor (including an AI control unit) 103, which is connected to the control unit 100. The microprocessor 103 is used to connect to an external wireless circuit unit 104, thereby enabling the device to connect to the Internet.

[0217] As shown in Figure 20, in the twentieth embodiment, the control unit 100 is connected to the internal wireless circuit unit 102. The internal wireless circuit unit 102 is wirelessly connected to an external router 105, which in turn connects to a computer 106 or the Internet, enabling control of the device via the computer 106. Alternatively, the internal wireless circuit unit 102 can be directly connected to a mobile phone 107, allowing control of the device via the mobile phone.

[0218] As shown in Figure 21, the first port 261 of the power adapter can be connected to the input port 131 of this device. This device has four output ports, namely output port 161, output port 262, output port 363 and output port 564.

[0219] As shown in Figure 22, the present invention also provides a power output distribution method for a power supply circuit, comprising the following steps:

[0220] The control unit obtains input power through various input terminals;

[0221] The control unit redistributes the acquired input power to each output terminal based on the output power of each output terminal;

[0222] The control unit detects whether the power circuits and data lines at the input and output terminals are directly connected or connected via a control switch. If so, it prioritizes allocating power to the output terminals that are directly connected or connected via a control switch to the power circuits and data lines at the input terminals.

[0223] As shown in Figures 23A, 23B, and 23C, after S1 starts, the control unit checks whether an electrical device is connected to output terminal 161 or output terminal 166. If an electrical device is connected, it proceeds to S2; otherwise, it proceeds to S3.

[0224] S2, the control unit closes the first switch unit 121, the second switch unit 122, and the third switch unit 123, and enters S4.

[0225] S4. Whether the control unit preferably (via APP) disconnects the first switch unit 121, the second switch unit 122 and the third switch unit 123. If not disconnected, proceed to S5. If disconnected, proceed to S6.

[0226] S5. Whether the control unit can preferentially (via APP) disconnect the second switch unit 122. If it is not disconnected, proceed to S7. If it is disconnected, proceed to S8.

[0227] S7, the power adapter communicates directly with port 331 of the device via the first switch unit 121, the second switch unit 122, and the third switch unit 123 to obtain the optimal charging solution (such as the power adapter from the mobile phone manufacturer) or directly charges port 336 of the device. This device prioritizes the charging requirements of port 331 and port 336 of the device (the priority order can be changed via App control). The control unit calculates the efficiency η by subtracting the power consumed by port 331 (Pom) from the maximum power output by the power adapter under the current voltages V331 and V336, and then calculating the remaining maximum power (Pirem) after reserving a margin. Proceed to S9. η = Pom / Pi = V336 * I336 / (V132 * I132)

[0228] Or η = Pom / Pi = V331*I331 / (V131*I131).

[0229] S9, the input voltage of the first DC-DC converter 111 (refer to Figure 1) or the third DC-DC converter 113 (refer to Figure 2) is equal to voltage V331 (ignoring the losses of the second switching unit 121, the third switching unit 123, and the wires). The charging voltage of port 331 of device one varies with the load requirements. When output port two 162 is detected to be connected to device two, after reading the various voltages and currents supported by the charging protocol of device two, the corresponding power Po1 can be obtained. The control unit determines whether the power Pirem > Po1. If yes, the output power Po1 is output at port 332 of device two; otherwise, the output power Pirem is output at port 332 of device two, and the efficiency η is calculated. Proceed to S10.

[0230] η=(Pom+Po1) / Pi=(V336*I336+V332*I332) / (V132*I132) or η=(Pom+Po1) / Pi=(V331*I331+V332*I332) / (V131*I131) (can be displayed on the terminal via APP).

[0231] S10, the control unit detects that output terminal 3163 is also connected to device 3. After reading the various voltages and currents supported by the charging protocol of device 3, the corresponding power Po2 can be obtained. The control unit determines whether the power Pirem > Po1 + Po2. If yes, device 3 port 333 outputs power Po2. If no, device 3 port 333 outputs power Pirem - Po1, or the power is split equally, or the power Po2 is given to device 3 port 333 first, and the remaining power Pirem - Po2 is given to device 2 port 332 (which can be determined according to the app priority selection indication), and the efficiency η is calculated.

[0232] 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) (This can be displayed on the terminal via the APP)

[0233] Since the load is variable, the control unit can select the most efficient output mode to meet the requirements of each load based on the current situation. First, it considers providing the maximum power to each load (at the start of charging). Once the power is sufficient, efficiency is considered. When the casing temperature is too high, high efficiency and reduced power are selected. Proceed to S18.

[0234] S18: The control unit monitors whether port 331 of the electrical equipment is fully charged (100%) or n%. If yes, proceed to S3. If no, end after completing all port tasks. (n% < 1, which can be set, such as 60% or 80%).

[0235] S8. When this device is connected to port 331 of the power-consuming equipment, it selects the highest voltage V331max from the charging scheme of port 331 of the power-consuming equipment to output power P331. Since the first switch unit (121) is closed, the voltage of the power adapter is equal to the voltage of port 331 of the power-consuming equipment. Therefore, 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 output power of port 331 of the power-consuming equipment is P331; if no, the output power of port 331 of the power-consuming equipment is Pv331max, with appropriate margin.

[0236] If device 1 port 331 is prioritized (or set in the App), when the output voltage of device 1 port 331 is V331, i.e., 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 device 1 port 331 is P331; otherwise, the output power of device 1 port 331 is Pv331*K (K is a margin coefficient less than 1), and calculates the efficiency η. Proceed to S11.

[0237] η = P331 / P131 = V331*I331 / (V131*I131) (can be displayed on the terminal via APP).

[0238] S11, the control unit detects that output terminal 2 162 is connected to device 2. After reading the various voltages and currents supported by the charging protocol of 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, device 2 outputs power Po1 at port 332; otherwise, device 2 outputs power Pv331max*K-P331 (or Pv331*K-P331) at port 332, and calculates the efficiency η. Proceed to S12.

[0239] η = P331 / P131 = (V331*I331 + V332*I332) / (V131*I131) (This can be displayed on the terminal via the APP)

[0240] S12, the control unit detects that output terminal 3163 is also connected to device 3. After reading the various voltages and currents supported by the charging protocol of device 3, the corresponding power Po2 can be obtained. The control unit determines whether the power Pv331max-P331-Po1>Po2 or Pv331-P331-Po1>Po2. If yes, device 3 port 333 outputs power Po2. If no, device 3 port 333 outputs power Pv331max-P331-Po1 or Pv331-P331-Po1, or the power is split equally, or the power Po2 is first satisfied and given to device 3 port 333, and the remaining power Pv331max-P331-Po2 or Pv331-P331-Po2 is then given to device 2 port 332 (which can be determined according to the app priority selection indication). Calculate the efficiency η.

[0241] η=(P331+Po1+Po2) / Pi=(V336*I336+V332*I332+V333*I333) / (V132*I132) or η=(P331+Po1+Po2) / Pi=(V331*I331+V332*I332+V333*I333) / (V131*I131) (This can be displayed on the terminal via the APP)

[0242] Since the load is variable, the control unit can select the most efficient output mode to meet the requirements of each load based on the current situation. First, it considers providing the maximum power to each load (at the start of charging). Once the power is sufficient, efficiency is considered. When the casing temperature is too high, high efficiency and reduced power are selected. Proceed to S19.

[0243] S19: The control unit monitors whether port 331 of the electrical equipment is fully charged (100%) or n%. If yes, proceed to S3. If no, end after completing all port tasks. (n% < 1, can be set, such as 60% or 80%).

[0244] S3, the control unit disconnects the first switch unit 121, the second switch unit 122, and the third switch unit 123, and proceeds to S6.

[0245] S6, the control unit determines whether there is a fifth DC-DC converter 115. If not, it proceeds to S13; if so, it proceeds to S17.

[0246] In step S13, the control unit first takes the maximum output voltage Vimax of the power adapter (or not) as the input voltage for either the first DC-DC converter 111 (refer to Figure 1) or the third DC-DC converter 113 (refer to Figure 2). At this time, the power adapter can provide a maximum power of Pimax0. If it is detected that output terminal 2 162 is connected to device 2, the optimal solution that supports the protocol of device 2 is first met, and the charging voltage of port 332 of device 2 changes with the load requirements. At this time, the output power corresponding to the voltage is Po1. The control unit determines whether the power Pimax0*K (K is a margin coefficient less than 1) > Po1. If yes, the output power of port 332 of device 2 is Po1; otherwise, the output power of port 332 of device 2 is Pimax0*K. Proceed to step S14.

[0247] In S13, a more cost-effective and simpler control scheme can also be used (refer to Figures 1 and 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 voltage V261 = V131 = V111i = V112i = Vomax + ΔV (approximately 1-2V, or not).

[0248] For example: V261 = 6-7V, 10-11V, 13-14V, 16-17V, 21-22V correspond to outputs of 5V, 9V, 12V, 15V, and 20V (PD3.0) respectively.

[0249] V261 = 29-30V, 37-38V, 49-50V correspond to outputs of 28V, 36V, and 48V (PD3.1) respectively.

[0250] For example, if the load requires 15V, adjust the input V261 to 16-17V; if it requires 36V, adjust the input V261 to 37-38V…

[0251] ΔV is 1-2V at low power (wearable devices, mobile devices). ΔV will be much larger at high power.

[0252] S14, obtain the efficiency η = Po1 / Pi = V332*I332 / (V131*I131) (all electronic information, including temperature and efficiency η, can be displayed on the App terminal). Gradually decrease (change) the power adapter voltage Vi to obtain the input voltage and corresponding efficiency. After a preliminary and rapid scan of all Vi voltages, the voltage corresponding to the highest efficiency is obtained as the input voltage. Dynamically monitor the output of the 332 port of the power device and select the input voltage according to the efficiency. At this time, the maximum output power of the power adapter is Pimax. Proceed to S15.

[0253] S15, the control unit detects that output terminal 3163 is connected to device 3. First, it satisfies the optimal solution according to the protocol supported by device 3, where the charging voltage at port 333 of device 3 changes with the load. At this time, the power corresponding to the voltage is Po2. The control unit determines whether the power Pimax*K (K is a margin coefficient less than 1) > Po1 + Po2. If yes, port 333 of device 3 outputs power Po2; otherwise, port 333 of device 3 outputs power Pimax*K - Po1, or the power is split evenly, or the power Po2 is first supplied to port 333 of device 3, and the remaining power Pimax*K - Po2 is then supplied to port 332 of device 3 (this can be determined according to the app's priority selection indication). Proceed to S16.

[0254] S16: After scanning all 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). Gradually decrease the voltage Vi to obtain the corresponding output parameters, and record the input voltage and corresponding efficiency. Select the voltage corresponding to the highest efficiency as the input voltage. Monitor the output of device two-port 332 and device three-port 333, dynamically allocate power (App priority), and select the input voltage according to the efficiency.

[0255] The control unit can select the most efficient output mode to meet the requirements of each load based on the situation. First, it considers providing the maximum power to each load (at the start of charging). Once the power is comparable, it then considers efficiency. When the casing temperature is too high, it selects high efficiency and reduces power.

[0256] Once all port tasks are completed, the process ends.

[0257] S17, the control unit first takes the maximum output voltage Vimax of the power adapter (or not) as the input voltage of the first DC converter 111 (Figure 1) or the third DC converter 113 (Figure 2). At this time, the maximum input power is Pimax0. If it is detected that the output terminal 161 is connected to the first device, the optimal solution that supports the protocol of the first device port 331 is first satisfied. The charging voltage of the first device port 331 changes with the load requirements. At this time, the power corresponding to the voltage is Pom. The control unit determines whether the power Pimax0*K>Pom. If yes, the output power of the first device port 331 is Pom; if no, the output power of the second device port 332 is Pimax0*K; proceed to S20.

[0258] In S17, there is a cost-effective and simple control scheme (refer to Figure 12): When the first DC converter 111, the second DC converter 112, and the second DC converter 115 are Buck converters, 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), making control simple.

[0259] Alternatively, 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 (approximately 1-2V, but may not be V).

[0260] V111i, V112i, and V115i are the input voltages of the first DC-DC converter 111, the second DC-DC converter 112, and the second DC-DC converter 115, respectively.

[0261] For example: V261 = 6-7V, 10-11V, 13-14V, 16-17V, 21-22V correspond to outputs of 5V, 9V, 12V, 15V, and 20V (PD3.0) respectively.

[0262] V261 = 29-30V, 37-38V, 9-50V corresponds to outputs of 28V, 36V, and 48V (PD3.1) respectively.

[0263] For example, if the load requires 15V, adjust the input V261 to 16-17V; if it requires 36V, adjust the input V261 to 37-38V.

[0264] In S20, the efficiency η = Pom / Pi = V331*I331 / (V131*I131) is obtained. The voltage Vi of the power adapter is gradually decreased to obtain the input voltage and corresponding efficiency. After a preliminary and rapid scan of all Vi voltages, the voltage corresponding to the highest efficiency is obtained as the input voltage. The output of port 331 of the power device is dynamically monitored, and the input voltage is selected according to the efficiency. At this time, the maximum output power of the power adapter is Pimax. Proceed to S21.

[0265] S21, the control unit detects that output terminal 2 162 is connected to device 2. First, it satisfies the optimal solution based on the protocol supported by device 2, where the charging voltage at port 332 of device 2 varies with the load. At this time, the power corresponding to the voltage is Po1. The control unit determines whether the power Pimax*K > Pom + Po1. If yes, port 332 of device 2 outputs power Po1; otherwise, port 332 of device 2 outputs power Pimax*K - Pom. Proceed to S22.

[0266] S22, the control unit detects that output terminal 3163 is connected to device 3. First, it satisfies the optimal solution according to the protocol supported by device 3, where the charging voltage at port 333 of device 3 varies with the load. At this time, the power corresponding to the voltage is Po2. The control unit determines whether the power Pimax*K > Pom + Po1 + Po2. If yes, port 333 of device 3 outputs power Po2; otherwise, port 333 of device 3 outputs power Pimax*K - Pom - Po1, either by splitting the power equally or by first satisfying the power Po2 requirement at port 333 of device 3, and then allocating the remaining power Pimax*K - Pom - Po2 to port 332 of device 3. Proceed to S23.

[0267] S23, after rescanning 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 status of the first port 331, the second port 332, and the third port 333 of the power device, dynamically allocate power, and select the input voltage according to the efficiency.

[0268] Once all port tasks are completed, the process ends.

[0269] Throughout the process, the control unit can control power adapter 2 to select the option that meets the following requirements according to priority:

[0270] (1) It meets all the energy requirements of output terminal 161, output terminal 2 162, and output terminal 3 163, and has high efficiency;

[0271] (2) The output terminals 161, 162, and 163 do not provide enough energy;

[0272] (3) It does not satisfy the requirement that all the energy provided by output terminal 161, output terminal 262, and output terminal 363 is the same and has high efficiency.

[0273] In the example, the order of output terminals 161, 162, and 163 is for illustrative purposes only and is variable.

[0274] As shown in Figure 23C, the flowchart of Figure 16 is applicable. S61, after starting, the detection output terminal is connected to the electrical equipment (let's say output terminal 161), and then proceeds to S62.

[0275] S62, the control unit requests the power adapter to charge output terminal 161 at high speed and completes the high-speed charging mode, then enters S63.

[0276] S63, Output terminal 161 exits the high-speed mode and switches to the optimal mode to charge output terminal 161 until output terminal 161 is fully charged, then enters S64.

[0277] S64, check whether the power supply is connected to output terminal 2 162 or output terminal 3 163 (if it is output terminal 2 162). If yes, proceed to S65; otherwise, proceed to S63.

[0278] S65, the control unit requests the power adapter to charge output terminal 2 162 at high speed, while the remaining power charges output terminal 1 161. Output terminal 2 162 completes the high-speed charging mode and enters S66.

[0279] S66, Output terminal 2 162 exits the high-speed mode and switches to fast mode. The control unit will charge output terminal 1 161 in the optimal way until output terminal 1 161 and output terminal 2 162 are fully charged (or the App selects priority), and then enters S67.

[0280] S67 checks whether output terminal 3163 is connected to an electrical device. If yes, proceed to S68; otherwise, proceed to S66.

[0281] S68, the control unit requests the power adapter to charge output terminal 3 163 at high speed, while the remaining power is used to charge output terminals 161 and 162. The high-speed charging mode of output terminal 162 is completed first, and then the process proceeds to S69.

[0282] S69, Output terminal 3 163 exits high-speed mode and switches to fast mode. The control unit will charge output terminal 1 161 in the optimal way until output terminal 1 161, output terminal 2 162, and output terminal 3 163 are fully charged (or select priority in the App).

[0283] Once all port tasks are completed, the process ends.

[0284] This invention uses the widely used Type-C and USB-C interfaces in its embodiments, but is not limited to these. Furthermore, the D+ / D- and CC1 / CC2 interfaces used in the USB-C interface are merely illustrative examples and are not limited to these.
