One-to-many charging devices have become an important means to solve the problem of charging multiple devices due to their convenience. As a specific application scenario of one-to-multiple devices, one-to-two charging cables have gradually attracted market attention due to their strong pertinence and limited number of devices.

[0003] Existing one-to-many charging technologies usually provide power support for connected devices by dynamically allocating power, and the allocation logic mainly depends on the device's protocol type, power requirements, and charging status. However, when dealing with multi-device connections, these technologies mainly focus on global power allocation. For scenarios where only two devices are connected, there is too much redundancy in their optimization logic and hardware configuration, making it difficult to fully exert their performance advantages.

DETAILED DESCRIPTION

[0024] The present application is further described in detail below in conjunction with the accompanying drawings.

[0025] In one embodiment, if Figure 1 As shown, the present application discloses a power distribution method for a one-to-two charging cable, which specifically includes the following steps: S10: Real-time detection of the main cable input power and the protocol characteristics, power requirements and charging status of the devices connected to the two branch cables, thereby establishing a bidirectional power coordination relationship.

[0026] Specifically, by collecting the input power value of the main cable in real time, monitoring its input current and voltage parameters, identifying the power fluctuation range, and reading the communication protocol information of the branch cable connection device, including the protocol type supported by the device, battery capacity and current power demand, after obtaining the device protocol characteristics, the power allocation ratio of each branch is dynamically calculated according to the charging status of the two branch devices, and a real-time adjusted two-way power coordination relationship is constructed based on the power allocation ratio, so that the dynamic power allocation of the two branch devices can adapt to changes in the device status, ensuring the balance and efficiency of power distribution.

[0027] S20: According to the bidirectional power coordination relationship, a charging phase complementary optimization mechanism is established between the connected devices, and the charging phase characteristics of the connected devices are detected, and charging coordination optimization is performed based on the charging phase characteristics.

[0028] Specifically, by collecting the real-time current and voltage changes of the two-branch devices and analyzing the charging stage of the device, including the fast charging stage, the constant voltage charging stage and the trickle charging stage, the power flow and priority allocation of the two-branch devices are dynamically adjusted according to the changing characteristics of the power demand in different stages. When the power demand difference is large, power is allocated to high-demand devices first. At the same time, the power of low-demand devices is dynamically controlled to avoid power waste. Through this collaborative optimization between charging stages, the charging efficiency is significantly improved.

[0029] S30: Analyze the input power of the main cable in real time. When the input power is abnormal, adjust the charging power of the connected device through the redundant buffer mechanism of the power coordination relationship.

[0030] Specifically, by monitoring the current and voltage fluctuations of the main cable input power, calculating whether the fluctuation range and frequency exceed the preset threshold range, when insufficient power input or drastic fluctuations are detected, the power abnormality analysis logic is triggered, and the power allocation of the main cable is dynamically adjusted according to demand priority. The power resources are buffered through the power coordination relationship, and branch devices with higher demand are supported first. At the same time, the power output to devices with lower demand is limited to ensure overall charging stability under power fluctuations.

[0031] S40: When any connected device completes charging and / or disconnects, obtain corresponding released power, and reversely adjust the charging paths of the remaining branches based on the released power.

[0032] Specifically, when a branch device completes charging or the user actively disconnects, the power output status of the device is monitored in real time, and the power allocation logic is readjusted according to the power value released by the device that has completed charging. The released power is preferentially allocated to another device that has not completed charging, and the charging path is dynamically optimized according to power demand, so that the utilization rate of power resources is improved while ensuring the charging stability of the remaining devices.

[0033] In one embodiment, if Figure 2 As shown, in step S10, a bidirectional power coordination relationship is established, which specifically includes: S11: Detect protocol characteristics of the connected device, obtain the maximum power support of the connected device, and generate an initial power allocation ratio according to the maximum power support and power demand.

[0034] Specifically, by parsing the communication protocol of the connected devices, extracting the core parameters such as the maximum voltage and current value supported by the protocol, combining the current battery level of the device and the actual power demand, the maximum power support value and real-time demand value of the two branch devices are calculated, and by comparing the device demand ratio, the initial power allocation ratio is generated, and the main cable power is dynamically allocated to the two branch devices to ensure high efficiency and stability in the initial connection stage.

[0035] S12: Collect the power change trend of the connected devices in real time, establish the power change correlation matrix between the connected devices, and dynamically adjust the power allocation ratio.

[0036] Specifically, by recording the voltage and current change trends of the two-branch equipment in real time, the power change curve of the equipment is generated, and these change data are organized into a time series. The mathematical model is used to calculate the power demand change correlation matrix between the two-branch equipment. The matrix describes the power demand weights and allocation priorities of the two devices. Through dynamic adjustment of the correlation matrix, the power allocation ratio of the two-branch equipment is optimized in real time, making the power allocation more in line with actual demand changes.

[0037] S13: Based on the charging status of the connected devices, a power complementary path between the connected devices is generated, thereby obtaining a bidirectional power coordination relationship.

[0038] Specifically, by analyzing the charging stage and current power status of the two-branch devices, when a device enters the low-power demand stage, its released power value is calculated, and the released power is reallocated to the other branch device through dynamic path planning to achieve power complementarity between branches. At the same time, the path priority is adjusted according to the power change trend to build a more efficient two-way power coordination relationship.

[0039] In one embodiment, if Figure 3 As shown, in step S20, that is, based on the bidirectional power coordination relationship, a charging phase complementary optimization mechanism is established between the connected devices, specifically including: S21: During the fast charging stage, the current change trend of the connected device is detected, and the corresponding demand fluctuation is analyzed according to the current change trend, and then power is allocated according to the demand fluctuation.

[0040] Specifically, by collecting the current change value of the device during the fast charging stage in real time, the upward or downward trend of the current power demand is determined, and the dynamic power demand range of the device is calculated based on the trend change. When the demand of the device fluctuates greatly, more power is allocated first to support its stable charging. At the same time, power allocation is reduced to branch devices with smaller demand fluctuations, so as to improve the adaptability and rapid response capability of the overall power distribution.

[0041] S22: During the constant voltage charging stage, the voltage change trend of the connected device is detected, and the corresponding loss range is analyzed according to the voltage change trend, and then the power distribution is adjusted according to the loss range.

[0042] Specifically, by real-time monitoring of the voltage changes of the device during the constant voltage stage, analyzing whether the device is in a state where the battery is close to being fully charged, and calculating the power loss of the device during charging based on the stability of the voltage changes, when it is detected that the device has entered a state where the voltage changes tend to be stable, its power allocation is dynamically reduced, and the excess power is allocated to another branch device to optimize the overall power utilization efficiency.

[0043] S23: During the trickle charging stage, the main cable input power is adjusted according to the bidirectional power coordination relationship to reduce power waste during the trickle charging stage.

[0044] Specifically, by detecting the real-time power demand of the device after it enters the trickle charging stage, analyzing the downward trend of power demand, calculating the minimum power threshold actually required by the device, and dynamically adjusting the input power output of the main cable, the released excess power is reallocated to another branch device or the total power input of the main cable is reduced to avoid power waste and improve overall efficiency.

[0045] In one embodiment, if Figure 4 As shown, in step S30, the input power of the main cable is analyzed in real time. In the case of abnormal input power, the charging power of the connected device is adjusted through the redundant buffer mechanism of the power coordination relationship, which specifically includes: S31: When 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 variation range, an input power abnormality message is triggered, and the power distribution is adjusted according to the current charging status of the connected device.

[0046] Specifically, by real-time monitoring of the voltage and current parameters of the main cable, when it is detected that the input power drops below the preset standard or fluctuates beyond the normal range, the abnormal event is recorded and a power fluctuation warning is generated. Combined with the current charging status of the device, the power allocation to low-demand devices is reduced first, and the remaining power is allocated to high-demand devices to ensure stable charging of key equipment.

[0047] S32: Building a branch power buffer according to the fluctuation amplitude of the input power until the input power returns to normal.

[0048] Specifically, by calculating the fluctuation amplitude and frequency of the input power, a portion of the power is dynamically allocated to the buffer zone. The buffer zone is used to store excess power to cope with power demand under fluctuating conditions. When the input power returns to normal, power is released from the buffer zone to compensate for the shortfall during the fluctuation period, ensuring that the charging process is not affected by abnormal input power.

[0049] In one embodiment, if Figure 5 As shown, in step S31, the power distribution is adjusted according to the current charging state of the connected device, specifically including: S311: When there is only one fast charging stage in the current charging state, power guarantee allocation is performed for the connected device in the fast charging stage, and the power corresponding to another connected device is adjusted to a safety threshold.

[0050] Specifically, by judging the charging status of the two-branch devices, when one of the devices is in the fast charging stage and the other is in the low power demand stage, most of the power of the main cable is preferentially allocated to the fast charging device, and the power output of the low power demand device is limited to a safe threshold range, ensuring efficient charging of the fast charging device.

[0051] S312: When the current charging states are both in the fast charging stage or neither is in the fast charging stage, randomly allocate power guarantee to any connected device, and adjust the power corresponding to the other connected device to a safety threshold.

[0052] Specifically, by detecting the real-time charging status of the two devices, when the two devices are in the fast charging or non-fast charging stage at the same time, a random selection logic is used to prioritize one device and limit the power of the other device to the lowest safety threshold, avoiding power overload due to high demand from both devices at the same time, and ensuring the stability of the overall system.

[0053] In one embodiment, if Figure 6 As shown, in step S32, a branch power buffer is constructed according to the fluctuation amplitude of the input power until the input power returns to normal, which specifically includes: S321: Determine the power capacity of the fractional power buffer zone by real-time monitoring of the fluctuation amplitude and frequency of the input power.

[0054] Specifically, by collecting the changing trend of input power, analyzing the impact of fluctuation frequency and amplitude on power demand, calculating the required buffer capacity according to the maximum fluctuation range, and updating the power allocation ratio of the buffer in real time, it is ensured that the buffer has sufficient power redundancy when the input power fluctuates.

[0055] S322: In case of input power fluctuation, buffer power resources are called to preferentially support the connected devices corresponding to the power guarantee allocation.

[0056] Specifically, when it is detected that input power fluctuations cause the power demand of the device to be unable to be met directly, the stored power resources are called from the buffer and allocated preferentially to high-demand devices to ensure that the charging process of key devices is not affected by fluctuations, while limiting the power allocation of low-demand devices to maintain overall power stability.

[0057] S323: When the input power returns to normal, the buffer power resource is released and allocated to the connected device corresponding to the safety threshold power.

[0058] Specifically, when the input power returns to the normal range, the excess power resources in the buffer zone are released to devices with low power requirements, and the power is allocated to a safe power range to optimize power utilization. At the same time, the buffer zone capacity is released for continued use in the event of subsequent abnormal fluctuations.

[0059] It should be understood that the size of the serial numbers of the steps in the above embodiments does 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 on the implementation process of the embodiments of the present application.

[0060] In one embodiment, a power distribution device for a one-to-two charging cable is provided, and the power distribution device for a one-to-two charging cable corresponds to the power distribution method for a one-to-two charging cable in the above embodiment. Figure 7 As shown, the power distribution device of the one-to-two charging cables includes a power detection module, an optimization mechanism module, an abnormality processing module, and a power regulation module. The detailed description of each functional module is as follows: The power detection module is used to 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 in real time, thereby establishing a two-way power coordination relationship; The optimization mechanism module is used to build a complementary optimization mechanism for the charging stage between the connected devices according to the bidirectional power coordination relationship, detect the charging stage characteristics of the connected devices, and perform charging coordination optimization based on the charging stage characteristics; The abnormality handling module is used to analyze the input power of the main cable in real time.
