Detailed Implementation

[0016] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1 The diagram illustrates an embodiment of a dual-power supply device control method according to the present invention. The device includes an AC power supply path, a DC power supply path, and a workload connecting the AC power supply path and the DC power supply path. In one specific embodiment, the dual-power supply device can be an electronic device. The AC power supply path can be used to connect to mains power, providing AC input and converting it to power the workload. The DC power supply path can be a battery pack, etc., used to provide DC input and convert it to power the workload. Figure 1In an embodiment of the dual-power supply device control method of the present invention shown, the control method includes: S1, when the device starts working, sequentially confirming the power supply status of the AC power supply path and the DC power supply path, and confirming the working status of the workload; S2, according to the working status of the workload, the power supply status of the AC power supply path and the DC power supply path, switching the AC power supply path and / or the DC power supply path to supply power to the workload; S3, according to the working status of the workload and the conduction status of the AC power supply path and the DC power supply path, setting the working parameters of the AC power supply path and / or the DC power supply path.

[0018] Based on step S1, the device can begin operating in a state where it is powered on and ready to perform a specific task. This process can be triggered according to user needs. For example, the device's operating mode can be set via a power switch or selection button, powering it on and activating the corresponding mode. At this point, the power supply status of the AC and DC power supply paths can be checked sequentially to confirm whether they are receiving power, and the operating status of the workload can also be confirmed. Because different workloads have different power consumption levels, the requirements for the operating status of the AC and / or DC power supply paths will also differ. "Having power" in the AC and DC power supply paths means that there is power input at the input terminals of both paths. However, it's important to understand that even if there is power input, it doesn't necessarily mean that the workload is being powered. The following process is needed to confirm whether one or both of the AC and DC power supply paths are required to power the workload.

[0019] Based on step S2, after obtaining the working status of the workload and the power supply status of the AC power supply path and DC power supply path, the AC power supply path and / or DC power supply path can be switched on as needed to supply power to the workload. It is understood that the AC power supply path and DC power supply path can supply power to the workload individually or simultaneously; the specific process depends on the working status of the workload and the power supply status of the AC and DC power supply paths.

[0020] Based on step S3, after determining the power supply status of the AC power supply path and the DC power supply path, the operating parameters of the activated power supply path, such as the AC power supply path and / or the DC power supply path, can be further determined according to the operating status of the workload. The ultimate purpose of setting the operating parameters of the AC power supply path and the DC power supply path is to control the power output of the AC power supply path and the DC power supply path.

[0021] like Figure 2As shown, in one embodiment, the dual-power supply device control method of the present invention includes: S11A, controlling the AC power supply path to be turned on when only the AC power supply path is powered; S12A, obtaining the rated output power of the AC power supply path and obtaining the target power of the workload according to the working state of the workload; S13A, setting the output power of the AC power supply path according to the target power of the workload when the rated output power of the AC power supply path is greater than or equal to the target power of the workload; S14A, setting the output power of the AC power supply path according to the rated output power of the AC power supply path when the rated output power of the AC power supply path is less than the target power of the workload.

[0022] Specifically, based on the above process, when it is confirmed that only the AC power supply path has power, the AC power supply path can be directly controlled to conduct, so as to supply power to the workload through the AC power supply path. Simultaneously, the rated output power of the AC power supply path and the target power of the workload are obtained. The target power of the workload is determined by the working state of the workload. That is, during specific operation, it can be obtained according to the working state set for the workload. Comparing the rated output power of the AC power supply path and the target power of the workload, if the rated output power of the AC power supply path is greater than or equal to the target power of the workload, it indicates that the AC power supply path can supply power to the workload normally. In this case, the output power of the AC power supply path can be set according to the target power of the workload. When the rated output power of the AC power supply path is less than the target power of the workload, the output power of the AC power supply path needs to be set according to its power supply capacity, i.e., its rated output power, to avoid overloading the AC power supply path.

[0023] Furthermore, such as Figure 3 As shown, in one embodiment, the dual-power supply equipment control method of the present invention further includes: S15A, when the rated output power of the AC power supply path is less than the target power of the workload, monitoring the power supply status of the DC power supply path in real time during the operation of the equipment; S16A, when the DC power supply path is powered, controlling the DC power supply path to be turned on, so as to set the output power of the DC power supply path according to the target power of the workload and the rated output power of the AC power supply path.

[0024] Specifically, when the rated output power of the AC power supply path is less than the target power of the workload, the workload is not operating in an ideal state. Therefore, during equipment operation, the power supply status of the DC power supply path is continuously monitored according to preset rules. When there is power input to the DC power supply path, such as when the battery pack is charged, the DC power supply path can be controlled to conduct, allowing the workload to simultaneously receive auxiliary power through the DC power supply path. The output power of the DC power supply path is set based on the target power of the workload and the rated output power of the AC power supply path. For example, the output power of the DC power supply path can be set to the difference between the target power of the workload and the rated output power of the AC power supply path.

[0025] It is understandable that when the rated output power of the AC power supply path is greater than the target power of the workload, the DC power supply path will not participate in the operation, regardless of whether there is power input, in order to save the energy of the battery pack.

[0026] like Figure 4 As shown, in one embodiment, the dual-power supply device control method of the present invention includes: S11B, controlling the DC power supply path to be turned on when only the DC power supply path is powered; S12B, obtaining the rated output power of the DC power supply path and obtaining the target power of the workload according to the working state of the workload; S13B, setting the output power of the DC power supply path according to the target power of the workload when the rated output power of the DC power supply path is greater than or equal to the target power of the workload; S14B, setting the output power of the DC power supply path according to the rated output power of the DC power supply path when the rated output power of the DC power supply path is less than the target power of the workload.

[0027] Specifically, based on the above process, when it is confirmed that only the DC power supply path has power, the DC power supply path can be directly controlled to conduct, so as to supply power to the workload through the DC power supply path. Simultaneously, the rated output power of the DC power supply path and the target power of the workload are obtained. The target power of the workload is determined by the working state of the workload. That is, during specific operation, it can be obtained according to the working state set for the workload. Comparing the rated output power of the DC power supply path and the target power of the workload, if the rated output power of the DC power supply path is greater than or equal to the target power of the workload, it indicates that the DC power supply path can supply power to the workload normally. In this case, the output power of the DC power supply path can be set according to the target power of the workload. When the rated output power of the DC power supply path is less than the target power of the workload, the output power of the DC power supply path needs to be set according to its power supply capacity, i.e., its rated output power, to avoid overloading the DC power supply path.

[0028] Furthermore, such as Figure 5As shown, in one embodiment, the dual-power supply device control method of the present invention further includes: S15B, when only the DC power supply path is powered, monitoring the power supply status of the AC power supply path in real time during the operation of the device; S16B, when the AC power supply path is powered, controlling the AC power supply path to be turned on; S17B, obtaining the rated output power of the AC power supply path, gradually increasing the output power of the AC power supply path according to the rated output power of the AC power supply path, and gradually decreasing the output power of the DC power supply path according to the target power of the workload and the rated output power of the AC power supply path.

[0029] Specifically, when only the DC power supply path is operational (i.e., only the DC power supply path is conducting), the AC power supply status is monitored in real-time according to preset rules during equipment operation. When the AC power supply path is operational, it is directly controlled to conduct, and its rated output power is obtained. Then, based on the rated output power of the AC power supply path, the output power of the AC power supply path is gradually increased, while the output power of the DC power supply path is gradually decreased. It can be understood that during the reduction of the DC power supply path's output power, the sum of the output power of the AC power supply path and the DC power supply path must be equal to the target power of the workload.

[0030] It is understandable that during the process of reducing the output power of the DC power supply path, including reducing the output power of the DC power supply path to zero as needed, and finally shutting down the DC power supply path and directly switching to the AC power supply path that is connected later.

[0031] like Figure 6 As shown, in one embodiment, the dual-power supply device control method of the present invention includes: S11C, controlling the AC power supply path to be turned on when both the AC power supply path and the DC power supply path are powered simultaneously; S12C, obtaining the rated output power of the AC power supply path and obtaining the target power of the workload according to the working state of the workload; S13C, setting the output power of the AC power supply path according to the target power of the workload when the rated output power of the AC power supply path is greater than or equal to the target power of the workload; S14C, setting the output power of the AC power supply path according to the rated output power of the AC power supply path and controlling the DC power supply path to be turned on when the rated output power of the AC power supply path is less than the target power of the workload, so as to set the output power of the DC power supply path according to the target power of the workload and the rated output power of the AC power supply path.

[0032] Specifically, when both the AC and DC power supply paths are powered, the AC power supply path is first activated. Simultaneously, the rated output power of the AC power supply path and the target power of the workload are obtained. The target power of the workload is determined by its operating state. Different operating states may correspond to the same or different target powers. When the rated output power of the AC power supply path meets the target power requirement of the workload, the output power of the AC power supply path can be directly set according to the target power of the workload. In this case, even if the DC power supply path is powered, it will not supply power to the workload. When the rated output power of the AC power supply path does not meet the target power requirement of the workload, the output power of the AC power supply path is directly set according to its rated output power. Simultaneously, the DC power supply path is activated so that it supplies power to the workload. In this case, the output power of the DC power supply path can be set by the target power of the workload and the rated output power of the AC power supply path; that is, the output power of the DC power supply path is set as the difference between the target power of the workload and the rated output power of the AC power supply path.

[0033] Furthermore, such as Figure 7 As shown, in one embodiment, the dual-power supply device control method of the present invention further includes: S15C, when the AC power supply path and the DC power supply path are simultaneously turned on, monitoring the power supply status of the AC power supply path and the DC power supply path in real time; S16C, when the power supply of the AC power supply path disappears, when the rated output power of the DC power supply path is greater than or equal to the target power of the workload, setting the output power of the DC power supply path according to the target power of the workload; when the rated output power of the DC power supply path is less than the target power of the workload, setting the output power of the DC power supply path according to the rated output power of the DC power supply path; S17C, when the power supply of the DC power supply path disappears, keeping the output power of the AC power supply path unchanged.

[0034] Specifically, when both AC and DC power supply paths are simultaneously active, their power supply status is monitored in real time. If the AC power supply fails, the output power of the DC power supply path needs to be set according to the target power of the workload. In this case, it's equivalent to only the DC power supply path providing power. During DC power supply, its rated output power must be considered to ensure it doesn't exceed its rated output power. In other words, during operation, the rated output power of the DC power supply path is compared to the target power of the workload. If the rated output power is greater than or equal to the target power, the DC power supply path can supply power normally to the workload, and its output power can be set according to the target power. If the rated output power is less than the target power, the output power needs to be set according to the DC power supply path's capacity (i.e., its rated output power) to prevent overloading.

[0035] If the DC power supply path loses power, the AC power supply path will remain unchanged because its output power is already at the rated output power. This will allow the AC power supply path to continue to output at the rated output power.

[0036] Furthermore, in one embodiment, the dual-power supply equipment control method of the present invention further includes: S18C, when the AC power supply path and the DC power supply path are simultaneously turned on, monitoring the working status of the workload; S19C, when the target power of the workload changes, adjusting the output power of the DC power supply path according to the change.

[0037] Specifically, when both AC and DC power supply paths are supplying power to the workload simultaneously, if the target power of the workload changes, the output power of the DC power supply path is adjusted according to the change. This is equivalent to prioritizing ensuring that the output power of the AC power supply path is at its rated output power.

[0038] In one specific embodiment, when the target power of the workload changes, the output power of the DC power supply path is adjusted accordingly. This includes controlling the DC power supply path to shut down when the target power of the workload is less than the rated output power of the AC power supply path, and setting the output power of the AC power supply path according to the target power of the workload. That is, when the target power of the workload changes to be less than the rated output power of the AC power supply path, the DC power supply path can be directly shut off to the workload, and the output power of the AC power supply path can be directly set according to the target power of the workload.

[0039] Furthermore, an electronic device according to the present invention includes: a controller, an AC power supply path, a DC power supply path, and a workload connecting the AC power supply path and the DC power supply path; the controller is used to implement the control method as described above. That is, the power supply process of the electronic device during operation can be realized through the above control method.

[0040] In one specific embodiment, the electronic device can be configured with different AC input states to accommodate multi-regional shipments. The commonly used US standard AC power plug specification of 120VAC / 15A is actually used in products with a power of less than 1800W, while high-pressure cleaners reach 1800W and typically use the US standard 120VAC / 20A power plug specification. However, when AC power supply is limited and cannot meet the demand for higher power, a DC power source can also operate simultaneously on top of AC power supply. This not only enables applications with higher power but also combines the advantages of AC / DC power supply modes.

[0041] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
