Description

Technical Field

[0001] The present application relates to the technical field of charging power distribution, and particularly to a power distribution method, device, equipment and medium for a one-to-two charging cable. Background Art

[0002] Currently, with the continuous increase in the types and quantities of electronic devices, users' demand for simultaneous charging of multiple devices is growing day by day. One-to-many charging devices have become an important means to solve the problem of multi-device charging due to their convenience. As a specific application scenario of one-to-many devices, the one-to-two charging cable has gradually attracted market attention due to its strong pertinence and limited number of devices.

[0003] Existing one-to-many charging technologies usually provide power support for connected devices through a method of dynamically allocating power, and their allocation logic mainly depends on the protocol type, power demand and charging status of the devices. However, when dealing with multi-device connections, these technologies mainly focus on global power distribution. For the scenario of only connecting two devices, there is too much redundancy in their optimization logic and hardware configuration, and it is difficult to fully exert their performance advantages. In addition, during the charging process, due to the lack of a dedicated optimization mechanism for the one-to-two scenario, existing technologies still have deficiencies in the refinement of power distribution, the collaborative optimization of the charging stage, and the adaptability to input power fluctuations.

[0004] The above-mentioned existing technical solutions have the following defects: in the one-to-two charging scenario, the existing power distribution method fails to fully consider the specific optimization requirements of dual-device connections, so there is room for improvement.

[0059] The present application will be further described in detail below with reference to the accompanying drawings.

[0060] In one embodiment, as Figure 1 shown, the present application discloses a power distribution method for a one-to-two charging cable, which specifically includes the following steps:

[0061] S10: Real-time detect the input power of the main cable and the protocol characteristics, power requirements, and charging status of the devices connected to the two branch cables, and then construct a two-way power coordination relationship.

[0062] Specifically, by real-time collecting the input power value of the main cable, monitoring its input current and voltage parameters, identifying the power fluctuation range, and at the same time reading the communication protocol information of the devices connected to the branch cables, including the protocol types supported by the devices, battery capacity, and current power requirements, after obtaining the protocol characteristics of the devices, dynamically calculate the power distribution ratio of each branch according to the charging status of the two branch devices, and construct a real-time adjusted two-way power coordination relationship in combination with the power distribution ratio, so that the dynamic power distribution of the two branch devices can adapt to the changes in the device status, ensuring the balance and efficiency of power distribution.

[0063] S20: According to the two-way power coordination relationship, construct a complementary optimization mechanism for the charging stage between connected devices, detect the charging stage characteristics of the connected devices, and perform charging coordination optimization based on the charging stage characteristics.

[0064] Specifically, by collecting the real-time current and voltage changes of the two branch devices, analyze the charging stage where the devices are located, including the fast charging stage, constant voltage charging stage, and trickle charging stage. According to the characteristics of power demand changes in different stages, dynamically adjust the power flow direction and priority allocation of the two branch devices. When the power demand difference is large, preferentially allocate power to the high-demand device, and at the same time dynamically control the power of the low-demand device to avoid power waste. Through this collaborative optimization between charging stages, the charging efficiency is significantly improved.

[0065] S30: Perform real-time analysis on the input power of the main cable. In the case of abnormal input power, adjust the charging power of the connected devices through the redundant buffering mechanism of the power coordination relationship.

[0066] Specifically, by monitoring the current and voltage fluctuations of the input power of the main cable, calculate whether the fluctuation range and frequency exceed the preset threshold range. When it is detected that the power input is insufficient or the fluctuation is severe, trigger the power anomaly analysis logic, dynamically adjust the power distribution of the main cable according to the demand priority, buffer the power resources through the power coordination relationship, preferentially support the branch devices with higher demand, and at the same time limit the power output to the devices with lower demand to ensure the overall charging stability under power fluctuations.

[0067] S40: When any connected device completes charging and / or disconnects, obtain the corresponding released power, and reverse-regulate the charging path of the remaining branches based on the released power.

[0068] Specifically, when the branch device completes charging or the user actively disconnects, real-time monitor the power output status of the device, re-adjust the power distribution logic according to the power value released by the completed charging device, preferentially allocate the released power to the other device that has not completed charging, and dynamically optimize the charging path according to the power demand, so as to improve the utilization rate of power resources and ensure the charging stability of the remaining devices at the same time.

[0069] In one embodiment, as Figure 2 shown, in step S10, that is, constructing the two-way power coordination relationship, specifically includes:

[0070] S11: Detect the protocol characteristics of the connected devices, obtain the maximum power support of the connected devices, and generate an initial power distribution ratio according to the maximum power support and power demand.

[0071] Specifically, by parsing the communication protocol of the connected device, core parameters such as the maximum voltage and current values supported by the protocol are extracted. Combining the current power level of the device's battery and the actual power demand, the maximum power support value and the real-time demand value of the two branch devices are calculated. By comparing the device demand ratio, an initial power distribution ratio is generated, and the main cable power is dynamically distributed to the two branch devices to ensure high efficiency and stability in the initial connection stage.

[0072] S12: Real-time collect the power change trend of the connected device, establish a power change correlation matrix between the connected devices, and dynamically adjust the power distribution ratio.

[0073] Specifically, by real-time recording the voltage and current change trends of the two branch devices, a power change curve of the device is generated. These change data are sorted into a time series, and a mathematical model is used to calculate the power demand change correlation matrix between the two branch devices. This matrix describes the power demand weights and distribution priorities of the two devices. By dynamically adjusting the correlation matrix, the power distribution ratio of the two branch devices is optimized in real time to make the power distribution more in line with the actual demand changes.

[0074] S13: Based on the charging status of the connected device, generate a power complementary path between the connected devices, and then obtain a two-way power coordination relationship.

[0075] Specifically, by analyzing the charging stage and the current power state of the two branch devices, when one device enters the low power demand stage, calculate the released power value, and redistribute the released power to the other branch device through dynamic path planning to achieve power complementarity between the branches. At the same time, adjust the path priority according to the power change trend to construct a more efficient two-way power coordination relationship.

[0076] In one embodiment, as Figure 3 shown, in step S20, that is, according to the two-way power coordination relationship, a charging stage complementary optimization mechanism is constructed between the connected devices, which specifically includes:

[0077] S21: In the fast charging stage, detect the current change trend of the connected device, analyze the corresponding demand fluctuation according to the current change trend, and then perform power distribution according to the demand fluctuation.

[0078] Specifically, by real-time collecting the current change value of the device in the fast charging stage, judge the rising or falling trend of the current power demand, calculate the dynamic power demand range of the device according to the trend change. When the demand fluctuation of the device is large, preferentially allocate more power to support its stable charging, and at the same time reduce the power distribution to the branch device with smaller demand fluctuation to improve the adaptability and fast response ability of the overall power distribution.

[0079] S22: During the constant-voltage charging stage, detect the voltage change trend of the connected device, analyze the corresponding loss range according to the voltage change trend, and then adjust the power distribution according to the loss range.

[0080] Specifically, by monitoring the voltage change of the device in the constant-voltage stage in real time, analyze whether the device is in a state where the battery charge is close to full, calculate the power loss during the charging process of the device according to the stability of the voltage change. When it is detected that the device enters a state where the voltage change tends to be stable, dynamically reduce its power distribution and allocate the excess power to another branch device to optimize the overall power utilization efficiency.

[0081] S23: During the trickle charging stage, adjust the input power of the main cable according to the two-way power coordination relationship to reduce power waste in the trickle stage.

[0082] Specifically, by detecting the real-time power demand of the device after it enters the trickle charging stage, analyze the power demand decline trend, calculate the minimum power threshold actually required by the device, dynamically adjust the input power output of the main cable, and reallocate the released excess power to another branch device or reduce the total power input of the main cable to avoid power waste and improve the overall efficiency.

[0083] In one embodiment, as Figure 4 shown, in step S30, that is, analyze the input power of the main cable in real time. In the case of abnormal input power, adjust the charging power of the connected device through the redundant buffer mechanism of the power coordination relationship, specifically including:

[0084] S31: In the case where the input power of the main cable is lower than the preset standard power and / or the fluctuation range of the input power of the main cable exceeds the preset normal change range, trigger an input power abnormal message, and then adjust the power distribution according to the current charging state of the connected device.

[0085] Specifically, by monitoring the voltage and current parameters of the main cable in real time, when it is detected that the input power drops below the preset standard or the fluctuation exceeds the normal range, record the abnormal event and generate a power fluctuation warning. Combining the current charging state of the device, preferentially reduce the power distribution of low-demand devices and allocate the remaining power to high-demand devices to ensure the stable charging of key devices.

[0086] S32: Construct a branch power buffer according to the fluctuation amplitude of the input power until the input power returns to normal.

[0087] Specifically, by calculating the fluctuation amplitude and frequency of the input power, dynamically allocate a part of the power to the buffer. The buffer is used to store the excess power to meet the power demand in the case of fluctuations. When the input power returns to normal, release the power from the buffer to compensate for the deficiency during the fluctuation period to ensure that the charging process is not affected by the abnormal input power.

[0088] In one embodiment, as Figure 5 shown, in step S31, that is, adjusting power distribution according to the current charging state of the connected device, specifically including:

[0089] S311: In the case where there is a unique fast charging stage in the current charging state, perform power guarantee allocation for the connected device in the fast charging stage, and adjust the power corresponding to the other connected device to the safety threshold.

[0090] Specifically, by judging the charging states of the two branch devices, when one device is in the fast charging stage and the other device is in the low power demand stage, preferentially allocate most of the power of the main cable to the fast charging device, and limit the power output of the low power demand device within the safety threshold range to ensure efficient charging of the fast charging device.

[0091] S312: In the case where the current charging states are both fast charging stages or neither are fast charging stages, randomly perform power guarantee allocation for any one of the connected devices, and adjust the power corresponding to the other connected device to the safety threshold.

[0092] Specifically, by detecting the real-time charging states of the two devices, when the two devices are both in the fast charging or non-fast charging stage, adopt a random selection logic to preferentially support one device, and limit the power of the other device to the lowest safety threshold to avoid power overload caused by the high demands of the two devices at the same time and ensure the stability of the overall system.

[0093] In one embodiment, as Figure 6 shown, in step S32, that is, constructing a branch power buffer according to the fluctuation amplitude of the input power until the input power returns to normal, specifically including:

[0094] S321: Determine the power capacity of the score power buffer by real-time monitoring of the fluctuation amplitude and frequency of the input power.

[0095] Specifically, by collecting the change trend of the input power, analyzing the influence of the fluctuation frequency and amplitude on the power demand, calculating the required buffer capacity according to the maximum fluctuation range, and real-time updating the power distribution ratio of the buffer to ensure that the buffer has sufficient power redundancy under the condition of input power fluctuation.

[0096] S322: In the case of input power fluctuation, call the buffer power resource to preferentially support the connected device corresponding to the power guarantee allocation.

[0097] Specifically, when it is detected that the input power fluctuation causes the power demand of the device not to be directly met, the stored power resources are called from the buffer and preferentially allocated to high-demand devices to ensure that the charging process of critical devices is not affected by the fluctuation, while restricting the power allocation of low-demand devices to maintain overall power stability.

[0098] S323: When the input power returns to normal, release the buffered power resources and allocate them to the connected devices corresponding to the safety threshold power.

[0099] Specifically, when the input power returns to the normal range, release the excess power resources in the buffer to the devices with low power demand, allocate this power to the safe power range to optimize the power utilization rate, and at the same time release the buffer capacity for continued use in case of subsequent abnormal fluctuations.

[0100] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
