Description

Technical Field

[0001] This invention belongs to the field of intelligent charging power allocation technology, specifically a method for intelligent charging power allocation. Background Technology

[0002] With the widespread adoption of mobile phones, computers, tablets, and other information devices, and the increasing demand from users for longer battery life and lighter designs, fast charging technology and docking station products are being used more and more extensively. In this environment, many similar external power-consuming devices have also acquired functions such as fast charging relay.

[0003] However, many external power-consuming devices have multiple USB ports that consume additional power during use, and chargers typically do not have sufficient power reserve to support this extra power consumption. Therefore, when the extra power consumption exceeds the charger's total load, insufficient power can lead to device malfunctions.

[0004] To address the aforementioned power deficiency issue, most products on the market currently employ a method of modifying the fast charging power protocol declaration to pre-deduct a certain amount of power. This pre-deducted power is then used to maintain the additional power consumption of the power-consuming device, thereby resolving the power deficiency problem. For example, the common PD fast charging relay technology, when fast charging relays an external power-consuming device, pre-deducts a certain amount of charging power during protocol declaration to maintain the additional power consumption of the external power-consuming device.

[0005] However, due to differences in charging definitions set by various information devices or their manufacturers, some devices may experience issues such as pop-up windows, charging refusal, or malfunctions when using external power-consuming devices that have undergone fast charging pre-charging. For example, some computers may forcibly limit the minimum charging power; if the pre-charged power is lower than this minimum limit, normal charging will not be possible.

[0006] Therefore, we propose a method for intelligent charging power allocation. Summary of the Invention

[0007] The purpose of this invention is to provide a method for intelligent charging power allocation in order to solve the problem of insufficient power or inability to use external power-consuming devices during fast charging transfer.

[0008] The technical solution adopted in this invention is as follows: A method for intelligent charging power distribution includes a fast charging relay device connecting a charger or power bank to a terminal device, comprising the following steps: S1: Charging power detection: Real-time acquisition of the initial charging power parameters input from the charger or power bank to the fast charging transfer device; S2: Power consumption monitoring and prediction: The microprocessor continuously monitors the power consumption of the fast charging transfer device itself and the additional power consumption of the expansion interface, and predicts the total power consumption requirement based on historical data; S3: Dynamic power adjustment: Based on the predicted total power consumption demand, dynamically reduce the actual charging power output to the terminal device without changing the declared power of the fast charging protocol; S4: Power Redistribution: The reduced charging power is redistributed to maintain the operation of the fast charging relay device and power the expansion interface.

[0009] In a preferred embodiment of the invention, the charging power detection includes identifying the type of fast charging protocol supported by the charger or power bank, acquiring input voltage and current data and calculating real-time input power values ​​through a power adjustment circuit, and transmitting the data to a microprocessor.

[0010] In a preferred embodiment of the invention, the power consumption monitoring and prediction includes establishing a power consumption prediction model, predicting the power consumption increment in the future period based on the type and number of access devices of the extended interface and real-time load fluctuations, and triggering a dynamic power adjustment command when the predicted total power consumption exceeds the input power threshold.

[0011] In a preferred embodiment of the invention, the dynamic power adjustment is achieved by a microprocessor controlling a power adjustment circuit to reduce the output voltage or current in priority order, and to ensure that the adjustment range satisfies the following: actual output power = input power - (device power consumption + predicted power consumption of expansion interface) + redundant buffer value.

[0012] In a preferred embodiment of the invention, the redundancy buffer value is dynamically set to 5%–10% of the predicted power consumption to avoid device restarts due to sudden load changes.

[0013] In a preferred embodiment of the invention, the power redistribution includes dividing the power distribution into levels: the first level ensures power supply for the core functions of the fast charging relay device; the second level distributes power to the expansion interface as needed; and when the expansion interface is unloaded, redundant power is automatically released to the charging channel of the terminal device.

[0014] In a preferred embodiment of the invention, the fast charging relay device includes a power adjustment circuit, a microprocessor, a multi-protocol expansion interface, and a current sensor. The power adjustment circuit is used to connect to the input terminal of a charger or power bank. The microprocessor is used to build in a power consumption prediction algorithm and power allocation logic. The multi-protocol expansion interface is used to support USB-C and QC3.0+ fast charging standards. The current sensor is used to monitor the load current of each interface in real time.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the microprocessor monitors the input power in real time and predicts the additional power consumption requirements of the expansion interface based on the power consumption prediction model. When the predicted total power consumption is close to or exceeds the input power threshold, the microprocessor dynamically reduces the actual charging power output to the terminal device without changing the declared power of the fast charging protocol. This solves the problem of insufficient power or inability to use external power-consuming devices during the fast charging transfer process.

[0016] 2. In this invention, the microprocessor divides power allocation into two levels. The first level prioritizes power supply to the core functions of the fast charging relay device, while the second level dynamically allocates power to the expansion interface as needed. When the expansion interface is unloaded, redundant power is automatically released to the charging channel of the terminal device, maximizing resource utilization and improving the user experience of docking stations, multi-port charging devices, and products that require fast charging relay for external power consumption.

[0017] 3. In this invention, the charging power detection first identifies the fast charging protocol type of the charger or power bank, and maintains the protocol-declared power unchanged through the power adjustment circuit. This ensures that the terminal device always perceives the standard fast charging capability, avoiding protocol errors or charging refusal caused by power adjustment. Moreover, the redundant buffer value acts as a dynamic safety cushion, absorbing prediction errors or load fluctuations and preventing compatibility interruptions. The power redistribution logic supports hot-swappable scenarios. When a new device is connected to the expansion interface, the system redistributes power immediately without needing to re-handshake the protocol, improving the compatibility of products that require pre-deducted power for fast charging transfer.

The actual charging power of the terminal device; the fast charging relay device includes a power adjustment circuit, a microprocessor, a multi-protocol expansion interface, and a current sensor.

The multi-protocol expansion interface is used to support USB-C and QC3.0+ fast charging standards. The current sensor is used to monitor the load current of each interface in real time. Specifically, the microprocessor monitors the input power in real time and predicts the additional power consumption requirements of the expansion interface according to the power consumption prediction model. When the predicted total power consumption is close to or exceeds the input power threshold, the microprocessor dynamically reduces the actual charging power output to the terminal device without changing the declared power of the fast charging protocol. This solves the problem of insufficient power or inability to use external power-consuming devices during fast charging relay. Example

[0022] Reference Figures 1-4 Power redistribution: The reduced charging power is redistributed to maintain the operation of the fast charging relay device and power supply to the expansion interfaces. Power redistribution includes dividing the power allocation into two levels. The first level ensures the power supply for the core functions of the fast charging relay device, while the second level allocates power to the expansion interfaces as needed. When the expansion interfaces are unloaded, redundant power is automatically released to the charging channel of the terminal device. Specifically, the microprocessor divides the power allocation into two levels. The first level prioritizes the power supply for the core functions of the fast charging relay device, such as the operation of the microprocessor and current sensor. The second level dynamically allocates power to the expansion interfaces, such as USB-C and QC3.0+ ports, as needed. When the expansion interfaces are unloaded, redundant power is automatically released to the charging channel of the terminal device, maximizing resource utilization and improving the user experience of docking stations, multi-port charging devices, and products that require fast charging relay for external power consumption. Example

[0023] Reference Figures 1-4Charging power detection includes identifying the fast charging protocol type supported by the charger or power bank. It collects input voltage and current data and calculates the real-time input power value through a power adjustment circuit, transmitting this data to the microprocessor. Dynamic power adjustment, controlled by the microprocessor, reduces the output voltage or current in a priority order, ensuring the adjustment range satisfies: Actual output power = Input power - (Device's own power consumption + Predicted power consumption of expansion interfaces) + Redundancy buffer value. The redundancy buffer value is dynamically set to 5%–10% of the predicted power consumption to prevent device restarts due to sudden load changes. Specifically, the power adjustment circuit fine-tunes the output voltage or current in a priority order to ensure that the actual output power = Input power - (Device's own power consumption + Predicted power consumption of expansion interfaces) + The redundant buffer effectively absorbs sudden load changes, preventing device crashes or restarts due to instantaneous overload. Charging power detection first identifies the fast charging protocol type of the charger or power bank and maintains the declared power of the protocol unchanged through a power adjustment circuit. This ensures that the terminal device always perceives the standard fast charging capability, avoiding protocol errors or charging refusal caused by power adjustment. Furthermore, the redundant buffer acts as a dynamic safety cushion, absorbing prediction errors or load fluctuations and preventing compatibility interruptions. The power redistribution logic supports hot-swapping scenarios; when a new device is connected to the expansion interface, the system instantly redistributes power without needing to re-handshake the protocol, improving the compatibility of products requiring pre-deducted power for fast charging.
