[0044] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be construed as limiting the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.
[0045] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.
[0046] It should be noted that the terms "first / second / third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific order for the objects. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.
[0047] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the field to which the embodiments of the present application belong. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as herein.
[0048] The MPPT function can detect the generated voltage of the solar panel in real time and track the maximum voltage and current values, so that the solar panel charges the battery with the maximum power output. In the related art, a power bank usually does not have a solar charging circuit and does not support the maximum power point tracking (MPPT) function. Although there are already some power banks with solar charging circuits, these power banks still have some defects. For example, they can achieve solar charging but do not support the MPPT function, and there are problems such as low solar energy utilization efficiency and small power; or they can also achieve solar charging and support the MPPT function, but an independent charging port needs to be introduced to support the MPPT function, resulting in problems such as high cost and too large a volume of the power bank.

In this way, on the one hand, since the MPPT function can be realized by feedbacking the mode adjustment signal through the first interface without adding an independent interface to realize the MPPT function, the cost of the power supply device is reduced and the volume of the power supply device is reduced at the same time; on the other hand, since the power supply device of the present application supports the MPPT function and can adjust the power supply signal input by the solar panel to a high power, the power supply power of the power supply device can be improved while the utilization efficiency of solar energy is improved.

[0083] In some embodiments, when the connection state between the solar panel and the first interface indicates that the solar panel is connected to the power management circuit, the mode adjustment signal fed back by the control module can switch the working mode of the power management circuit to the power adjustment mode.
[0084] In some embodiments, the power management circuit may further include a voltage detection module and a load module. The voltage detection module is connected to the first interface. The voltage detection module is used to obtain the first power supply signal and feed back the first power supply signal to the control module. The control module is connected to the load module. The control module is further used to determine that the solar panel is connected to the power management circuit through the first interface and the power management circuit when the power supply parameters of the first power supply signal meet the preset conditions, and / or to adjust the loading degree of the load module when obtaining the first power supply signal to obtain the load signal corresponding to the first power supply signal; and to determine that the solar panel is connected to the power management circuit through the first interface when the load signal corresponding to the first power supply signal conforms to the working curve corresponding to the solar panel.
[0085] In an embodiment of the present application, the power supply device includes: a battery; a solar panel for providing a first power supply signal; a power management circuit connected to the solar panel through a first interface, the power management circuit being connected to the battery, and the power management circuit being configured to generate a second power supply signal based on the first power supply signal and charge the battery based on the second power supply signal when the power supply parameters of the received first power supply signal meet a preset condition; a control module connected to the power management circuit, the control module being configured to adjust a mode adjustment signal according to the connection state feedback mode of the solar panel and the first interface, and the mode adjustment signal being used to adjust the working mode of the power management circuit. In this way, on the one hand, since the MPPT function can be realized by feedback the mode adjustment signal through the first interface without adding an independent interface to realize the MPPT function, the cost of the power supply device is reduced and the volume of the power supply device is reduced; on the other hand, since the power supply device of the present application can support the MPPT function and can adjust the power supply signal input by the solar panel to a high power, the power supply power of the power supply device can be improved and the utilization efficiency of solar energy can be improved while.
[0086] In some embodiments, the power supply device further includes: a power supply component connected to the power management circuit through the first interface, the power supply component being configured to provide a third power supply signal to the power management circuit; the power management circuit is further configured to generate a fourth power supply signal based on the third power supply signal and charge the battery based on the fourth power supply signal when a charging signal is detected.
[0087] Here, the power supply component refers to a component that can supply electrical energy to the power supply device. The power supply component can be any suitable component that can implement this function. For example, a power adapter, a fixed power supply, a power bank, etc. A power adapter is a power supply conversion device for electronic devices and electrical appliances and can supply power to the power supply device.
[0088] In some embodiments, the power supply component is connected to the power management circuit through the first interface. The first interface can be any suitable interface, such as a USB interface, a Lightning interface, etc. The power supply component is configured to provide a third power supply signal to the power management circuit. The third power supply signal and the fourth power supply signal refer to signals for supplying electrical energy.
[0089] In some embodiments, the third power supply signal and the fourth power supply signal have power supply parameters. The power supply parameters can include but are not limited to at least one of the following: supply current, supply voltage, supply power, etc. In implementation, the power supply parameters of the third power supply signal and the fourth power supply signal are different, and the power supply parameters of the fourth power supply signal are suitable for the power supply requirements of the battery.
[0090] In some embodiments, when the connection state between the power supply component and the first interface indicates that the power supply component is connected to the power management circuit, the mode adjustment signal fed back by the control module can switch the operating mode of the power management circuit to the DC power supply mode. In some embodiments, the power management circuit will generate a fourth power supply signal based on the third power supply signal and charge the battery only when a charging signal is detected. The charging signal may include, but is not limited to, one of the following: CC (Charger Configuration) signal, CP (Charge Pilot) signal, etc. The CC signal is mainly used for communication between the power supply component and the power supply device to identify and negotiate charging parameters, and is mostly used in USB Type-C interfaces and some new charging interfaces. The CP signal is used to control the switching state of the charger to ensure the safety of the charging process.
[0091] In some embodiments, the power management circuit includes a power conversion module, which can be used to generate a fourth power supply signal based on the third power supply signal and charge the battery based on the fourth power supply signal.
[0092] In the embodiments of the present application, the power supply component can be connected to the power management circuit through the first interface, so that the power management circuit generates a fourth power supply signal based on the third power supply signal provided by the power supply component and charges the battery when a charging signal is detected. Thus, power supply in the conventional charging scenario is supported through the first interface, improving the compatibility of the power supply device. Since the MPPT function can also be realized by feeding back the mode adjustment signal through the first interface, the cost of the power supply device is reduced and the volume of the power supply device is reduced at the same time.
[0093] In some embodiments, the power management circuit includes a protocol chip and a power conversion module; the control module is connected to the protocol chip, and the control module is further configured to feed back a mode adjustment signal to the protocol chip when the solar panel is connected to the power management circuit; the protocol chip is connected to the power conversion module, and the protocol chip is configured to switch the operating mode to the power adjustment mode based on the mode adjustment signal and send a power adjustment signal to the power conversion module; the power conversion module is configured to perform power conversion on the first power supply signal based on the power adjustment signal to determine the second power supply signal.
[0094] Here, the protocol chip is an integrated circuit that integrates the functions of power management and charging protocol control. The protocol chip can receive the mode adjustment signal sent by the control module, switch the operating mode to the power adjustment mode based on the mode adjustment signal, and send a power adjustment signal to the power conversion module.
[0095] The power conversion module can convert the input power supply signal into a power supply signal that meets the battery specifications. In some embodiments, the power conversion module can adjust the power supply parameters of the power supply signal, so as to convert the input power supply signal into a power supply signal that meets the battery specifications.
[0096] In some embodiments, the power conversion module can be any suitable element capable of implementing this function. For example, a bidirectional Buck-Boost, a charge pump, etc. The bidirectional Buck-Boost is a special power converter that can automatically adjust the output voltage according to the level of the input voltage, so as to achieve the step-up and step-down functions of the power supply. The charge pump is a circuit that uses the charging and discharging of capacitors to achieve voltage conversion and can convert the input voltage.
[0097] In some embodiments, since the power supply device needs to enter the power adjustment mode to implement the MPPT function when connecting to the solar panel, the control module needs to feedback a mode adjustment signal to the protocol chip when the solar panel is connected to the power management circuit, so that the protocol chip switches the working mode to the power adjustment mode based on the mode adjustment signal.
[0098] In some embodiments, a microcontroller or chip supporting the MPPT function can be built into the protocol chip. Therefore, the protocol chip can be used to switch the working mode to the power adjustment mode based on the mode adjustment signal and send a power adjustment signal to the power conversion module.
[0099] In some embodiments, after receiving the power adjustment signal sent by the protocol chip, the power conversion module can perform power conversion on the first power supply signal to determine the second power supply signal.
[0100] In some embodiments, the power management circuit further includes a switch circuit. When the protocol chip switches the working mode to the power adjustment mode based on the mode adjustment signal, the switch circuit can receive the control signal sent by the protocol chip and adjust the connection state of the power management circuit to the connection state required for the power adjustment mode. In implementation, the switch circuit can be an HV-Gate switch circuit. The HV-Gate switch circuit is a switch circuit used to control high-voltage devices, and its core function is to achieve efficient and reliable power management by controlling the gate voltage of the high-side switch.
[0101] In some embodiments, the control module may be connected to the protocol chip via an Inter-Integrated Circuit (IIC) bus. The protocol chip may be connected to the power conversion module via the IIC bus. The IIC bus is a multi-master, two-wire, low-speed serial communication bus, which is widely used for communication between microcontrollers and various peripheral devices. It uses two lines: a serial data line and a serial clock line for bidirectional transmission.
[0102] In the embodiments of the present application, the protocol chip of the power management circuit switches the working mode to the power adjustment mode based on the mode adjustment signal fed back by the control module, and sends a power adjustment signal to the power conversion module of the protocol chip, so that the MPPT function can be implemented by the microcontroller or processing chip built in the protocol chip, without adding an additional microcontroller or processing chip for implementing the MPPT function, while reducing the structural complexity of the power supply device and further reducing the volume of the power supply device.
[0103] In some embodiments, the power management circuit includes a protocol chip and a power conversion module; the control module is connected to the protocol chip, and the control module is further configured to feed back a mode adjustment signal to the protocol chip when the solar panel is connected to the power management circuit; the protocol chip is connected to the power conversion module, and the protocol chip is configured to switch the working mode to the power adjustment mode based on the mode adjustment signal; the control module is connected to the power conversion module, and the control module is further configured to send a power adjustment signal to the power conversion module when the working mode is the power adjustment mode; the power conversion module is configured to perform power conversion on the first power supply signal based on the power adjustment signal to determine the second power supply signal.
[0104] Here, the protocol chip can receive the mode adjustment signal sent by the control module, switch the working mode to the power adjustment mode based on the mode adjustment signal, and send a power adjustment signal to the power conversion module.
[0105] The power conversion module can adjust the power supply parameters of the power supply signal, so as to be able to convert the input power supply signal into a power supply signal that meets the battery specifications. In some embodiments, the power conversion module may be any suitable element capable of implementing this function, such as a bidirectional Buck-Boost, a charge pump, etc.
[0106] In some embodiments, since the power supply device needs to enter the power adjustment mode to implement the MPPT function when connected to the solar panel, the control module needs to feed back a mode adjustment signal to the protocol chip when the solar panel is connected to the power management circuit, so that the protocol chip switches the working mode to the power adjustment mode based on the mode adjustment signal.
[0107] In some embodiments, since the processing capabilities of the microcontroller or chip built into the protocol chip are relatively weak, it is necessary to add a microcontroller or chip that supports the MPPT function inside the control module or in the power management circuit. After the working mode is switched to the power adjustment mode, the control module can send a power adjustment signal to the power conversion module.
[0108] In some embodiments, after receiving the power adjustment signal sent by the protocol chip, the power conversion module can perform power conversion on the first power supply signal to determine the second power supply signal.
[0109] In some embodiments, the power management circuit further includes a switching circuit. When the protocol chip switches the working mode to the power adjustment mode based on the mode adjustment signal, the switching circuit can receive the control signal sent by the protocol chip and adjust the connection state of the power management circuit to the connection state required for the power adjustment mode. In implementation, the switching circuit can be an HV-Gate switching circuit.

The solar panel 11 is connected to the switching circuit 41, the load module 42, and the voltage detection module 43 through the first interface 14. The switching circuit 41 is connected to the power conversion module 45 and the protocol chip 44. The protocol chip 44 is connected to the power conversion module 45 and the control module 13 through the IIC bus. The power conversion module 45 is connected to the battery 15.
[0121] In Figure 4A , a single-chip microcomputer or chip supporting the MPPT function can be built in the protocol chip 44. Therefore, the protocol chip 44 can be used to switch the working mode to the power adjustment mode based on the mode adjustment signal and send a power adjustment signal to the power conversion module 45.
