Description

Technical Field

[0001] The present invention relates to the field of power supply equipment technology, and in particular to a power transmission method and system based on power supply equipment during the secondary charging process. Background Technology

[0002] With the development of technology, power supply equipment is used as a backup for energy storage. Charging equipment charges the power supply equipment and performs multiple charges. The charging equipment connects to the power supply equipment for the first time, and the power supply equipment is charged for the first time. During the charging process, the charging equipment disconnects from the power supply equipment and connects to the power supply equipment again, and the power supply equipment is charged for the second time.

[0003] In the existing technology, the power supply equipment is in the second charging stage and is charged according to the charging efficiency of the first charging. However, there is an idle time between the second charging and the first charging. The current power supply equipment does not take the idle time into account during the second charging and charges according to the previous charging efficiency, which makes it impossible to control the overall charging time of the power supply equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. This invention provides a power transmission method and system based on a power supply device during secondary charging. When the charging device is disconnected from the power supply device and then reconnected, the power supply device is in a secondary charging phase. The secondary charging phase of the power supply device is controlled, and charging data from the first charging is collected to obtain the first charging efficiency and idle time. Secondary charging logic is constructed based on the first charging efficiency and idle time to adjust the power transmission efficiency of the power supply device. The parameters of the first charging efficiency and idle time are introduced to control the secondary charging in terms of efficiency and time factors, ensuring overall charging time control of the power supply device. The second charging time is adjusted based on the charging efficiency of the second charging. At this time, the power supply device triggers the replacement of the corresponding charging line according to the output of the secondary charging logic, and performs secondary charging based on the corresponding power transmission efficiency. The secondary charging process of the power supply device is monitored, and real-time charging parameters of the power supply device are collected. If the real-time charging parameters of the power supply device exceed a preset range, the self-regulation mechanism of the power supply device is triggered, and a backup power supply is connected.

[0005] To address the aforementioned technical problems, this invention provides a power transmission method for a power supply device during a secondary charging process. The method includes: when a charging device is disconnected from and reconnected to a power supply device, the power supply device is undergoing secondary charging; collecting charging data from the first charging cycle to obtain a first charging efficiency and idle time; constructing secondary charging logic based on the first charging efficiency and idle time, and adjusting the power transmission efficiency of the power supply device based on the secondary charging logic; triggering the replacement of the corresponding charging line as the secondary charging logic outputs, and performing secondary charging on the charging device based on the corresponding power transmission efficiency; monitoring the secondary charging process of the power supply device and collecting real-time charging parameters of the power supply device; if the real-time charging parameters of the power supply device exceed a preset range, triggering the self-regulation mechanism of the power supply device and connecting to a backup power source.

[0006] In addition, this embodiment of the invention also provides a power transmission system based on a power supply device during a secondary charging process. The power transmission system includes: a power module for the power supply device to be in a secondary charging state when it is reconnected to the power supply device after being disconnected; an acquisition module for acquiring charging data from the first charging cycle, obtaining a first charging efficiency and idle time; a control module for constructing secondary charging logic based on the first charging efficiency and idle time, and controlling the power transmission efficiency of the power supply device based on the secondary charging logic; a line module for the power supply device to trigger the replacement of the corresponding charging line as the secondary charging logic is output, and to perform secondary charging on the charging device based on the corresponding power transmission efficiency; a monitoring module for monitoring the secondary charging process of the power supply device and acquiring real-time charging parameters of the power supply device; and a backup module for triggering the self-regulation mechanism of the power supply device and connecting to a backup power source if the real-time charging parameters of the power supply device exceed a preset range.

[0007] In this embodiment of the invention, when the charging device is disconnected from the power supply device and then reconnected, the power supply device is in a secondary charging phase. The secondary charging phase of the power supply device is managed, and charging data from the first charging cycle is collected to obtain the first charging efficiency and idle time. Secondary charging logic is constructed based on the first charging efficiency and idle time to adjust the power transmission efficiency of the power supply device. The parameters of the first charging efficiency and idle time are introduced to control the secondary charging in terms of efficiency and time factors, ensuring overall charging time management of the power supply device. The second charging time is adjusted based on the charging efficiency of the second charging cycle. At this time, the power supply device triggers the replacement of the corresponding charging line according to the output of the secondary charging logic, and performs secondary charging based on the corresponding power transmission efficiency. The secondary charging process of the power supply device is monitored, and real-time charging parameters of the power supply device are collected. If the real-time charging parameters of the power supply device exceed a preset range, the self-regulation mechanism of the power supply device is triggered, and a backup power supply is connected.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example

[0017] Please see Figures 1 to 4 A power transmission method based on a power supply device during secondary charging, the method comprising:

[0018] S11: When the charging device is disconnected from the power supply device and then reconnected to the power supply device, the power supply device is in the process of recharging.

[0019] In the specific implementation of this invention, the specific steps can be as follows:

[0020] S111: The charging device is brought close to the power supply device and is connected to the power supply device for the first time;

[0021] S112: Obtain the docking signal between the charging device and the power supply device, and record the first charging time and charging progress of the power supply device;

[0022] S113: When the charging device is disconnected from the power supply device and then reconnected to the power supply device, the power supply device is in a secondary charging state.

[0023] Specifically, the system acquires the docking signal between the charging device and the power supply device, and records the first charging time and charging progress of the power supply device. This allows for the determination of the first charging time and charging progress of the power supply device during the first charging cycle, and serves as reference data for the second charging cycle, enabling overall control of the power supply device's charging process.

[0024] S12: Collect the charging data table of the power supply device during the first charge, and obtain the first charging efficiency and no-load time;

[0025] In the specific implementation of this invention, the specific steps can be as follows:

[0026] Collect charging data table of the power supply device during the first charge; traverse the charging data table of the first charge and obtain the first charging efficiency and idle time; form a corresponding relationship table based on the first charging efficiency and idle time; introduce adjustment parameters based on the relationship table, and adjust the curve shape of the relationship table based on the adjustment parameters.

[0027] Specifically, the charging data table for the first charge is traversed to obtain the first charging efficiency and idle time. The first charging efficiency and idle time are used as the basis for adjusting the second charge, and a corresponding relationship table is formed based on the first charging efficiency and idle time.

[0028] Furthermore, adjustment parameters are introduced based on a relationship table, and the curve shape of the relationship table is adjusted based on these parameters. In this case, the adjustment parameters can be environmental parameters or loss parameters. The concept of parameter adjustment can be freely introduced based on the replacement of these adjustment parameters, and it can adapt to various environmental applications to accommodate the environmental adjustments of power supply equipment.

[0029] S13: Construct secondary charging logic based on the first charging efficiency and idle time, and regulate the power transmission efficiency of the power supply equipment based on the secondary charging logic;

[0030] In the specific implementation of this invention, the specific steps can be as follows:

[0032] S132: Output the control result based on the secondary charging learning model, and adjust the power transmission efficiency of the power supply equipment based on the control result.

[0033] In this process, the previous first charging efficiency and idle time are input into the learning model, and the first charging efficiency and idle time are dimensionality reduced to output the second charging learning model. At this time, the second charging learning model serves as the result of the second charging logic, and the second charging of the power supply device is adjusted along the framework of the second charging logic. In this process, the second charging learning model adjusts the charging efficiency of the power supply device in real time, and ensures the stability and integrity of the second charging of the power supply device, thereby reducing the charging time of the second charging.

[0034] S14: The power supply device triggers the replacement of the corresponding charging line as the secondary charging logic is output, and performs secondary charging on the charging device based on the corresponding power transmission efficiency.

[0035] In the specific implementation of this invention, the specific steps can be as follows:

[0036] S141: In the control result of the secondary charging logic, the charging efficiency of the power supply device in the secondary charging is changed based on the control result. At this time, the charging efficiency of the secondary charging is adjusted based on the charging time of the secondary charging.

[0037] S142: The charging efficiency of the secondary charge is fixed by design, and the charging efficiency of the secondary charge is limited.

[0038] S143: The charging device is recharged based on the charging efficiency of the second charging.

[0039] In the control results of the secondary charging logic, the charging efficiency of the power supply device in the secondary charging is changed based on the control results. At this time, the charging efficiency of the secondary charging is adjusted based on the charging time of the secondary charging, and the charging efficiency of the secondary charging is fixed by design.

[0040] The solidified design based on the charging efficiency of secondary charging ensures the continuous stability of the charging efficiency. Furthermore, the charging efficiency of secondary charging is guaranteed by adjusting the internal structure. At this time, the charging efficiency of secondary charging will not change. The adjustment of the internal structure can be based on the parameter changes between multiple dimensions.

[0041] S15: Monitor the secondary charging process of the power supply equipment and collect the real-time charging parameters of the power supply equipment;

[0042] In the specific implementation of this invention, the specific steps include: monitoring the secondary charging process of the power supply device and collecting the real-time charging parameters of the power supply device; forming a corresponding charging parameter library from multiple real-time charging parameters; traversing the charging parameter library and filtering the corresponding deviation parameters based on the charging parameter library; performing self-checks on the power supply device along the deviation parameters and adjusting the deviation parameters of the power supply device to ensure the stability of the charging efficiency of the secondary charging.

[0043] S16: If the real-time charging parameters of the power supply exceed the preset range, the self-regulation mechanism of the power supply will be triggered, and the backup power supply will be connected.

[0044] In the specific implementation of this invention, the specific steps include: if the real-time charging parameters of the power supply device exceed the preset range, the self-regulation mechanism of the power supply device is triggered; the real-time charging parameters are screened and fixed within the preset range; the real-time charging parameters exceeding the preset range are adjusted based on the self-regulation mechanism of the power supply device, and the corresponding component's operating parameters are adjusted, or a backup power supply can be connected.

[0045] The purpose of this invention is to overcome the shortcomings of existing technologies.

Secondary charging logic is constructed based on the first charging efficiency and idle time to adjust the power transmission efficiency of the power supply device. The parameters of the first charging efficiency and idle time are introduced to control the secondary charging in terms of efficiency and time factors, ensuring overall charging time control of the power supply device. The second charging time is adjusted based on the charging efficiency of the second charging. At this time, the power supply device triggers the replacement of the corresponding charging line according to the output of the secondary charging logic, and performs secondary charging based on the corresponding power transmission efficiency. The secondary charging process of the power supply device is monitored, and real-time charging parameters of the power supply device are collected.
