Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a portable platform, a charging and discharging method for the portable platform, and a storage medium. Background Technology

[0002] Existing charging and discharging control systems for internal and external batteries cannot simultaneously charge both the internal and external batteries. External batteries typically come with dedicated chargers or charging managers, making them redundant. Electronic products usually only have one battery, resulting in limited battery life and requiring constant charging. For example, in outdoor scenarios where continuous operation is needed without power, only power banks or high-capacity batteries can provide continuous power, causing inconvenience for outdoor applications. Summary of the Invention

[0003] Based on this, this application provides a portable platform, a charging and discharging method for the portable platform, and a storage medium.

[0004] In a first aspect, this application provides a mobile platform, the mobile platform comprising:

[0005] The first battery and the second battery are used to power the mobile platform;

[0006] The first power management module is used to control the external charging power supply to charge the first battery;

[0007] The second power management module is used to control the external charging power supply to charge the second battery.

[0008] Secondly, this application provides a charging and discharging method for a portable platform, the method comprising:

[0009] The first power management module controls an external charging power supply to charge the first battery or controls the first battery to supply power to the system load of the mobile platform according to a preset charging and discharging control strategy.

[0010] And / or, the second power management module controls an external charging power supply to charge the second battery or controls the second battery to supply power to the system load of the mobile platform according to a preset charging and discharging control strategy.

[0011] Thirdly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to implement the charging and discharging method of the portable platform as described above.

[0012] This application provides a portable platform, a charging and discharging method for the portable platform, and a storage medium. The portable platform includes: a first battery and a second battery for supplying power to the portable platform; a first power management module for controlling an external charging power supply to charge the first battery; and a second power management module for controlling an external charging power supply to charge the second battery. Because the first power management module and the second power management module of the portable platform in this embodiment can control the external charging power supply to charge the first battery and the second battery respectively, the portable platform can charge the two batteries separately through the two power management modules. When one battery is removable, it is equivalent to an external battery, and when the other battery is not removable, it is equivalent to an internal battery. The portable platform can charge both the internal battery and the external battery, which can improve the integration of product functions and eliminate the need for redundant specially equipped electrical appliances or charging managers for external batteries. The fully charged external battery can also support the continuous operation of the portable platform, which can adapt to application scenarios such as those that require long battery life and continuous operation outdoors without interruption of power. It eliminates the need to carry additional power banks / large-capacity batteries and is convenient for outdoor applications. Therefore, the portable platform of this application embodiment provides technical support for charging both the internal battery and the external battery, and provides technical support for the continuous operation of the portable platform.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0026] Existing charging and discharging control systems for internal and external batteries cannot simultaneously charge both the internal and external batteries. External batteries require dedicated chargers or charging managers, which is redundant. Electronic products with only one battery have limited battery life and require constant charging; for continuous outdoor operation, they can only be powered by power banks or high-capacity batteries, causing inconvenience for outdoor applications.

[0027] This application provides a portable platform, a charging and discharging method for the portable platform, and a storage medium. The portable platform includes: a first battery and a second battery for supplying power to the portable platform; a first power management module for controlling an external charging power supply to charge the first battery; and a second power management module for controlling an external charging power supply to charge the second battery. Because the first power management module and the second power management module of the portable platform in this embodiment can control the external charging power supply to charge the first battery and the second battery respectively, the portable platform can charge the two batteries separately through the two power management modules. When one battery is removable, it is equivalent to an external battery, and when the other battery is not removable, it is equivalent to an internal battery. The portable platform can charge both the internal battery and the external battery, which can improve the integration of product functions and eliminate the need for redundant specially equipped electrical appliances or charging managers for external batteries. The fully charged external battery can also support the continuous operation of the portable platform, which can adapt to application scenarios such as those that require long battery life and continuous operation outdoors without interruption of power. It eliminates the need to carry additional power banks / large-capacity batteries and is convenient for outdoor applications. Therefore, the portable platform of this application embodiment provides technical support for charging both the internal battery and the external battery, and provides technical support for the continuous operation of the portable platform.

[0028] See Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of the mobile platform of this application. It should be noted that the mobile platform in this embodiment can refer to various platforms that can move automatically or under controlled conditions through their own power system, such as: gimbals (e.g., gimbal cameras, etc.), drones, vehicles, unmanned vehicles, ground robots, unmanned boats, etc. The mobile platform can also be a portable platform or electronic device that can change position when carried by a moving third party, such as: consumer electronics (including mobile terminals, mobile phones, etc.), industrial and agricultural electronic products (e.g., remote controls, etc.), etc.

[0029] The mobile platform 100 includes: a first battery 1, a second battery 2, a first power management module 3, and a second power management module 4.

[0030] The first battery 1 and the second battery 2 are used to supply power to the mobile platform 100; the first power management module 3 is used to control the external charging power supply to charge the first battery 1 and the second battery 2; the second power management module 4 is used to control the external charging power supply to charge the second battery 2.

[0031] In this embodiment, the first battery 1 and the second battery 2 are used to power the mobile platform 100. Typically, they power the system load of the mobile platform (i.e., all power-consuming terminals inside the mobile platform 100). The system load may have its own power system, which can convert the power supplied to the system load into different power domains for system use through boost and buck conversion.

[0032] In this embodiment, the first battery 1 and the second battery 2 can provide all the power required by the system, regardless of the battery capacity or voltage and current. Depending on the product form, the power supply battery can be designed to be removable or non-removable. For example, for mobile phones currently on the market, for reliability and other factors, the second battery 2 supplying power to the mobile platform can be designed as a non-removable built-in battery. The first battery 1 can be understood as a backup battery and can have various forms. The first battery 1 can usually be designed as a removable external battery for easy replacement. The first battery 1 and the second battery 2 can be lithium batteries or any other type of rechargeable battery.

[0033] Typically, battery series-parallel connection specifications are indicated as follows: 1s indicates a single battery being used, with a nominal voltage of approximately 3.7V; 2s indicates two batteries being used in series, with a nominal voltage of approximately 7.4V. 1p indicates a single battery pack being used; 2p indicates two battery packs being used in parallel. For example, 2s2p means two batteries are connected in series, and two battery packs are connected in parallel.

[0034] It should be noted that the first battery 1 in this embodiment can be interconnected with the first power management module 3 of the portable platform 100 through a custom battery interface or other standard battery interfaces. In fact, the first battery 1 can supply power to the portable platform 100 through various interfaces, such as USB Type-C and USB Micro-usb interfaces, all of which can serve as interfaces for the first battery. Broadly speaking, a power bank can also be considered a first battery in consumer electronics products.

[0035] In this embodiment, the first power management module 1 and the second power management module 2 can quickly and effectively distribute external charging power to the first battery 1 and the second battery 2 respectively, enabling the first battery 1 and the second battery 2 to be charged. When the first battery 1 and the second battery 2 are used as power sources, the first power management module 1 and the second power management module 2 can effectively distribute the power of the first battery 1 and the second battery 2 to the mobile platform 100 respectively, enabling the first battery 1 and the second battery 2 to supply power to the mobile platform 100.

[0036] The first power management module 3 and the second power management module 4 can be integrated circuits (ICs) for power management, or they can be self-designed charge and discharge management circuits, as long as they can realize some or all of the charge and discharge management functions for charging the first battery and the second battery, and charging and discharging the first battery and the second battery.

[0037] To improve integration, the first power management module 3 and the second power management module 4 can typically be charge / discharge management modules, which can be implemented using charge / discharge management chips. Various power chip manufacturers have their own unique charge / discharge management chips, such as Texas Instruments, MPS, and Analog Devices (ADI). Charge / discharge management chips are usually programmable, communicate with the system's main control chip, are controlled by the system, and implement corresponding charging logic. For example, in very mature consumer electronics products like mobile phones, the built-in charge / discharge management integrated circuit (IC) enables various charging mode management, charging status management, and reverse charging functionality. Charge management chips typically feature high integration, high precision, small packaging, and power path management capabilities, making them particularly suitable for use in consumer electronics.

[0038] In this embodiment, the first battery 1 is charged by the first power management module 3 and the second battery 2 is charged by the second power management module 4. This allows for more flexible and convenient control and management of the first battery 1 and the second battery 2. In particular, when the specifications and models of the first battery 1 and the second battery 2 are very different, using two power management modules can more flexibly and conveniently control and manage the first battery 1 and the second battery 2 respectively.

[0039] In practical applications, the mobile platform connects to various charging adapters and chargers with different functions, including fast charging and slow charging. For example, a slow charging adapter generally refers to an adapter that can only output 5V and 0.5A voltage and current; a fast charging adapter generally refers to an adapter with a charging protocol (such as QC or PD protocol) that can achieve 5V and 2A or higher voltage and current. In this embodiment, the charging protocols for fast charging of the first and second batteries include, but are not limited to, QC fast charging and PD fast charging, and any charging protocol implementation method applied to the charging and discharging of the first and second batteries is included.

[0040] The portable platform of this application embodiment includes: a first battery and a second battery for supplying power to the portable platform; a first power management module for controlling an external charging power supply to charge the first battery; and a second power management module for controlling an external charging power supply to charge the second battery. Because the first power management module and the second power management module of the portable platform in this embodiment can control the external charging power supply to charge the first battery and the second battery respectively, the portable platform can charge the two batteries separately through the two power management modules. When one battery is removable, it is equivalent to an external battery, and when the other battery is not removable, it is equivalent to an internal battery. The portable platform can charge both the internal battery and the external battery, which can improve the integration of product functions and eliminate the need for redundant specially equipped electrical appliances or charging managers for external batteries. The fully charged external battery can also support the continuous operation of the portable platform, which can adapt to application scenarios such as those that require long battery life and continuous operation outdoors without interruption of power. It eliminates the need to carry additional power banks / large-capacity batteries and is convenient for outdoor applications. Therefore, the portable platform of this application embodiment provides technical support for charging both the internal battery and the external battery, and provides technical support for the continuous operation of the portable platform.

[0041] See Figure 2 In one embodiment, the first power management module 3 and the second power management module 4 are connected, and the first power management module 3 can be connected to an external charging power source. In this way, the structure of the mobile platform 100 can be made more compact.

[0042] In addition to managing and controlling the charging of the first battery 1 and the second battery 2, the first power management module 3 and the second power management module 4 also need to manage and control the discharging of the first battery 1 and the second battery 2. In order to further improve the integration and better adapt to and meet the different charging and discharging needs of users for the first battery 1 and the second battery 2, in one embodiment, the first power management module 3 is also used to control an external charging power supply to charge the first battery 1 or control the first battery to supply power to the system load of the mobile platform 100 according to a preset charging and discharging control strategy; and / or, the second power management module 4 is also used to control an external charging power supply to charge the second battery 2 or control the second battery 2 to supply power to the system load of the mobile platform 100 according to a preset charging and discharging control strategy.

[0043] The first power management module 3 is connected to an external charging power source (either directly or indirectly), to the first battery 1, and to the second power management module 4. The second power management module 4 is connected to the first power management module 3, to the second battery 2, and to the system load of the movable platform 100 (either directly or indirectly) at one end.

[0044] In this embodiment, the preset charge and discharge control strategy can refer to the control strategy for charging and discharging the first battery and the second battery that is preset based on the characteristics of the first battery and the second battery themselves (e.g., the first battery and the second battery have different capacities), the characteristics of the mobile platform itself, the actual application scenario, user needs, etc.

[0045] The preset charging and discharging control strategy involves the system control strategy when the mobile platform is used in the whole electronic product. In specific implementation, a system software controller, in conjunction with a programmable control module and a hardware system, can be used to control the charging and discharging of the battery.

[0046] The system software controller, such as a microcontroller (MCU) or system-on-chip (SoC) interconnection signal, implements charge and discharge logic control through system software control. In one embodiment, the first power management module 3 and the second power management module 4 are charge and discharge management modules, and the block diagram of the charge and discharge management module is shown below. Figure 3 As shown, the charge / discharge management module has a battery terminal (for connecting the battery), a charging power supply terminal (for connecting the charging power supply), a load terminal (for connecting the system load), and a system software controller. The charge / discharge management module mainly implements the power path management function of the charging power supply, battery, and back-end load.

[0047] The following section details the preset charge and discharge control strategy.

[0048] In one embodiment, the preset charging and discharging control strategy is initially divided into a power-off charging strategy and a power-on charging strategy based on whether the mobile platform is powered off or powered on.

[0049] When the first power management module 3 is detected to be connected to an external charging power source, the power-off or power-on state of the mobile platform 100 is detected. When the mobile platform 100 is in the power-off state, the first power management module 3 and the second power management module 4 control the external charging power source to charge the first battery 1 and the second battery 2 according to the power-off charging strategy.

[0050] When the mobile platform 100 is powered on, the first power management module 3 and the second power management module 4 control the external charging power supply to charge the first battery 1 and the second battery 2 according to the power-on charging strategy.

[0051] In this embodiment, the difference between charging while the device is off and charging while the device is on is that charging while the device is off does not require consideration of system consumption, while charging while the device is on requires consideration of power-on losses and prioritizes the allocation of power input from the external charging power source to meet the system's needs.

[0052] In one embodiment, the preset charging and discharging control strategy is divided into four cases based on whether the mobile platform is powered off or powered on and whether fast charging is possible: fast charging strategy for the first and second batteries when powered off, fast charging strategy for the first and second batteries when powered on, slow charging strategy for the first and second batteries when powered off, and slow charging strategy for the first and second batteries when powered on.

[0053] When an external charging power source is detected to be a fast charging power source, the first power management module 3 and the second power management module 4 control the external charging power source to fast charge the first battery 1 and the second battery 2 according to the fast charging strategy of the first battery and the second battery in the power-off state, or the first power management module 3 and the second power management module 4 control the external charging power source to fast charge the first battery 1 and the second battery 2 according to the fast charging strategy of the first battery 1 and the second battery 2 in the power-on state.

[0054] Specifically, when an external charging power source is detected to be a slow charging power source, the first power management module 3 and the second power management module 4 control the external charging power source to charge the first battery 1 and the second battery 2 according to the slow charging strategy of the first battery and the second battery in the power-off state, or the first power management module 3 and the second power management module 4 control the external charging power source to charge the first battery 1 and the second battery 2 according to the slow charging strategy of the first battery and the second battery in the power-on state.

[0055] Normally, if the battery temperature is below a certain temperature (e.g., 0°C) or above a certain temperature (e.g., 45°C), the battery cannot be charged. Therefore, in one embodiment, the battery temperature needs to be detected before charging. When the first power management module 3 detects that an external charging power source is connected, the battery temperature is detected. When the battery temperature is within the rechargeable temperature range, the first power management module 3 and the second power management module 4 control the external charging power source to charge the first battery 1 and the second battery 2; when the battery temperature is outside the rechargeable temperature range, the first power management module 3 and the second power management module 4 control the external charging power source not to charge the first battery 1 and the second battery 2.

[0056] In one embodiment, the first power management module 3 and the second power management module 4 control the external charging power supply to perform equal charging on the first battery 1 and the second battery 2 based on their respective charge levels. The first battery 1 is removable; when the first battery 1 is detected to be removed, the second power management module 4 controls the external charging power supply to charge the second battery 2.

[0057] Typically, the battery with the lowest charge is charged first. When the first and second batteries reach the same charge level, they are then charged evenly. Specifically, the first power management module 3 controls the external charging power supply to prioritize charging the first battery 1 (lower charge), or the second power management module 4 controls the external charging power supply to prioritize charging the second battery 2 (lower charge). When the first and second batteries reach the same charge level, the first and second power management modules 3 and 4 control the external charging power supply to perform equal charging on both batteries.

[0058] In one embodiment, when the external charging power source is detected to be a fast charging power source, the second power management module 4 controls the external charging power source to prioritize charging the second battery 2.

[0059] Because the power adapter and other components charge the second battery 2 via the first power management module 3 and the second power management module 4, the charging efficiency of the second battery 2 is relatively lower than that of the first battery 1. Therefore, when the power adapter and other components are capable of fast charging the battery, the second battery 2 is charged first.

[0060] There are several ways to detect the power-off or power-on state of the mobile platform 100. In one embodiment, a power-on / off control module is positioned in front of the system load in the direction of the current flowing to the system load. This module allows the mobile platform 100 to detect its own power-off or power-on state and also controls the power supply to the system load. Specifically, the mobile platform 100 further includes a power-on / off control module 5, such as... Figure 4 As shown.

[0061] The power-on / off control module 5 is used to detect whether its own power-on button is pressed, thereby determining whether the portable platform 100 is in a powered-on or powered-off state. When the portable platform 100 is determined to be powered on, the first battery 1 and / or the second battery 2 can supply power to the system load; when the portable platform 100 is determined to be powered off, the first battery 1 and / or the second battery 2 cannot supply power to the system load.

[0062] Based on the above, the specific content of the preset charge and discharge control strategy may also include the following:

[0063] In one embodiment, the first battery 1 is removable. When the first power management module 3 detects that it is not connected to an external charging power source, it detects whether the first battery 1 is in place. When the first battery 1 is detected to be in place, the first power management module 3 controls the first battery 1 to supply power to the system load of the mobile platform according to the first battery in place discharge strategy, and / or the second power management module 4 controls the second battery 2 to supply power to the system load according to the first battery in place discharge strategy. When the first battery 1 is detected to be out of place, the second power management module 4 controls the second battery 2 to supply power to the system load according to the second battery discharge strategy.

[0064] In one embodiment, when the presence of the first battery 1 is detected, the charge levels of the first battery 1 and the second battery 2 are detected. When the charge levels of the first battery 1 and the second battery 2 are equal, the first power management module 3 and the second power management module 4 control the first battery 1 and the second battery 2 to work together to supply power to the system load.

[0065] In one embodiment, when the presence of the first battery 1 is detected, the charge levels of the first battery 1 and the second battery 2 are detected. When the charge level of the first battery 1 is greater than the charge level of the second battery 2, and the charge level of the second battery 2 is greater than a charge threshold, the first power management module 3 controls the first battery 1 to supply power to the system load. Until the charge levels of the first battery 1 and the second battery 2 are equal, the first power management module 3 and the second power management module 4 control the first battery 1 and the second battery 2 to work together to supply power to the system load.

[0066] In one embodiment, when the presence of the first battery 1 is detected, the charge levels of the first battery 1 and the second battery 2 are detected. When the charge level of the first battery 1 is greater than the charge level of the second battery 2, and the charge level of the second battery 2 is less than a charge threshold, the first power management module 3 controls the first battery 1 to supply power to the system load. Simultaneously, the first power management module 3 and the second power management module 4 control the first battery 1 to charge the second battery 2. When the charge level of the second battery 2 equals the charge threshold, the first power management module 3 and the second power management module 4 control the first battery 1 to stop charging the second battery 2. When the charge levels of the first battery 1 and the second battery 2 are equal, the first power management module 3 and the second power management module 4 control the first battery 1 and the second battery 2 to work together to supply power to the system load.

[0067] In one embodiment, when the charge of the first battery 1 is greater than the charge of the second battery 2, and the charge of the second battery 2 is less than a charge threshold, the first power management module 3 controls the first battery 1 to supply power to the system load. At the same time, the first power management module 3 and the second power management module 4 control the first battery 1 to charge the second battery 2. When the charge of the second battery 2 has not yet reached the charge threshold during the charging process, and the charges of the first battery 1 and the second battery 2 are equal, the first power management module 3 and the second power management module 4 control the first battery 1 and the second battery 2 to work together to supply power to the system load.

[0068] In one embodiment, to control the orderly supply of power to the system load by the first battery 1 and the second battery 2, the branch supplying power to the system load by the first battery 1 and the branch supplying power to the system load by the second battery 2 are separated, and two anti-backflow modules are added to the two branches. The conduction and cutoff of the two anti-backflow modules control the orderly supply of power to the system load by the first battery 1 and the second battery 2. Even if the first battery 1 is removed during the power supply process, the second battery 2 can continue to supply power to the system load. Even if the first battery 1 is not in place and the second battery 2 is inserted during the power supply process, the first battery 1 will not be disconnected from the system load, thus meeting the user's hot-swappable requirement for the first battery 1. Therefore, the movable platform 100 further includes: a first anti-backflow module 6 and a second anti-backflow module 7, such as... Figure 5 As shown.

[0069] The first backflow prevention module 6 is disposed between the first power management module 3 and the power on / off control module 5. When the voltage of the end of the first backflow prevention module 6 near the first power management module 3 is greater than the voltage of the end near the power on / off control module 5, the first backflow prevention module 6 is turned on, enabling the first battery 1 to supply power to the system load. When the voltage of the end of the first backflow prevention module 6 near the first power management module 3 is less than the voltage of the end near the power on / off control module 5, the first backflow prevention module 6 is turned off.

[0070] The second backflow prevention module 7 is disposed between the second power management module 4 and the power on / off control module 5. When the voltage of the end of the second backflow prevention module 7 closest to the second power management module 4 is greater than the voltage of the end closest to the power on / off control module 5, the second backflow prevention module 7 is turned on, enabling the second battery 2 to supply power to the system load. When the voltage of the end of the second backflow prevention module 7 closest to the second power management module 4 is less than the voltage of the end closest to the power on / off control module 5, the second backflow prevention module 7 is turned off.

[0071] Both the first anti-backflow module and the second anti-backflow module are Or-ing devices or diodes.

[0072] The input of the first backflow prevention module 6 comes from the first power management module 3, and the input of the second backflow prevention module 7 comes from the second power management module 4. The outputs of the first backflow prevention module 6 and the second backflow prevention module 7 are connected to each other and to the input of the power-on / off control module 5. The power supply from the first backflow prevention module 6 and the second backflow prevention module 7 is only provided to the downstream system load after the system is powered on. The input of the power-on / off control module 5 is connected to the outputs of the first backflow prevention module 6 and the second backflow prevention module 7, and the output of the power-on / off control module 5 is connected to the system load. The input of the system load is connected to the output of the power-on / off control module 5.

[0073] Backflow prevention modules isolate each input terminal to prevent mutual interference. Commonly used backflow prevention modules include dedicated backflow prevention circuits, diodes, or oscillating devices, or any module that can achieve backflow prevention. Diodes have unidirectional conduction characteristics, enabling backflow prevention. In high-power applications, oscillating devices are typically used to achieve high-efficiency backflow prevention, significantly improving circuit efficiency.

[0074] In one embodiment, to enable the mobile platform 100 to not only charge and supply power to its own internal components but also to supply power to an external load in reverse, and to improve integration, the mobile platform 100 further includes: an interface connector 8 and a third anti-backflow module 9, such as... Figure 6 As shown.

[0075] One end of the interface connector 8 is connected to an external power adapter 10 or an external load 11. When the first power management module 3 detects that the interface connector 8 is connected to an external charging power source through the external power adapter 10, the first power management module 3 controls the first battery 1 to charge and / or the second power management module 4 controls the second battery 2 to charge. When the first power management module 3 detects that the interface connector 8 is connected to an external load 11, it controls itself to disconnect from the interface connector 8.

[0076] The third backflow prevention module 9 is disposed between the interface connector 8 and the system load. When the voltage of the third backflow prevention module 9 near the system load is greater than the voltage near the interface connector 8, the third backflow prevention module 9 is turned on, enabling the first battery 1 and / or the second battery 2 to supply power to the external load 11. When the voltage of the third backflow prevention module 9 near the system load is less than the voltage near the interface connector 8, the third backflow prevention module 9 is turned off.

[0077] In this embodiment, the interface connector 8 includes interfaces of various protocols, including but not limited to USB interfaces, such as USB Type-C, USB Type-A, USB micro-B, or other types of interface connectors. Taking the USB Type-C interface as an example, the interface includes VCC and GND pins, enabling functions such as charging the portable platform 100 from an external power source and reverse power supply from the portable platform 100. The interface may also include communication pins related to the USB 3.0 protocol to implement communication functions.

[0078] Interface connector 8 is connected to external power adapter 10, which outputs different power specifications to the mobile platform (depending on the capabilities of external power adapter 10 itself, as well as the input voltage and current configuration and charging protocol of the first power management module 3); external power adapter 10 can be any charging head, power bank, or other battery-type item that can stably output rated voltage and current.

[0079] Interface connector 8 can also be connected to an external load 11. If interface connector 8 is no longer connected to the external power adapter 10, but instead connected to an external load 11 (such as a mobile phone), the external load 11 will trigger the OTG function of the interface, and the portable platform 100 will output power. The default output voltage is generally 5V, but this can be adjusted according to the actual application scenario. The interface connector can be a USB-Type-C connector, and the external load can be a load conforming to the USB specification. For example, low-power devices such as keyboards and mice will draw a maximum of 100mA of current from the interface, while high-power devices such as mobile phones will draw a maximum of 500mA of current.

[0080] The output terminal of the third backflow prevention module 9 is connected to the input terminal of the interface connector 8 and the charging power terminal of the first power management module 3. When the OTG function is enabled and the product outputs current, the first power management module 3 is in charging off mode, and the charging power terminal of the first power management module 3 is turned off.

[0081] In one embodiment, in order to control the power supply to the external load 11 and to limit the magnitude of the current output to the external load 11, the movable platform 100 further includes: a current limiting switch control module 12, such as... Figure 6 As shown.

[0082] The current limiting switch control module 12 is located between the third anti-backflow module 9 and the system load. When it is detected that the interface connector 8 is connected to an external load 11, it controls the opening of its own switch to output current to the external load 11 and limits the magnitude of the output current.

[0083] In this embodiment, the main function of the current limiting switch control module 12 is to: after the system enables OTG, open the current limiting switch to allow the portable platform 100 to output power externally; and limit the rated output current, for example, to 0.5A or 1.5A. Different specifications of current limiting switches can be selected according to different application scenarios. In this way, the application scenarios of the portable platform can be expanded.

[0084] The output of the current limiting switch control module 12 is connected to the third anti-backflow module 9 to prevent the external charging power supply from affecting the current limiting switch control module 12 and the system load 1 in application scenarios where the system is being charged by a normal external charging power supply.

[0085] The portable platform 100 of this application embodiment can meet the user's need to charge the first battery 1 and the second battery 2. It can realize the charging management of the first battery 1 and the second battery 2 without the need for an additional charging adapter or charging manager, reducing redundant charging devices. While improving the experience, it maintains the original needs of meeting the user's needs for hot-swappable removable first battery 1, uninterrupted long battery life, and reverse power supply to external devices.

[0086] In particular, the mobile platform 100 in this embodiment can be a remote controller, especially a remote controller for agricultural / industrial drones, for use in harsh outdoor operating environments. Theoretically, it can achieve 24 / 7 operation, uninterrupted long battery life, and fast charging.

[0087] The following is combined Figure 6 The practical application of the embodiments of this application is explained in detail by taking the design of different charging strategies based on the different capacities of the first battery and the second battery as an example. The first battery can be a removable external battery, and the second battery can be a non-removable internal battery.

[0088] The first battery has a capacity of 5200mAh and a 2s capacity; the second battery has a capacity of 2600mAh and a 2s capacity. The mobile platform uses a design with one first battery and one second battery. In a practical application, the charging strategy for the internal and external batteries of this mobile platform is as follows:

[0089] When both the first and second batteries are in place and fully charged, based on the characteristics of the mobile platform's own hardware, the two anti-backflow modules work together to simultaneously supply power to the system load. Specifically, this may include the following:

[0090] (1) The mobile platform 100 consumes the power of the first battery 1 and the second battery 2 simultaneously. The internal and external batteries switch discharges together through the coordination of the anti-backflow module. Before the second battery 2 is completely consumed, the second power management module 4 will control the cessation of consuming the power of the second battery 2 and reserve 5 minutes (the 5 minutes set here is just a specific example and can be adjusted according to the actual application) of power for the system to use when switching the first battery 1.

[0091] (2) Based on the results of (1), when the system alarms for low battery (or at any time before the low battery alarm), the user can hot-swap the first battery 1 to switch it off while working outdoors without shutting down the system. When the first battery 1 is removed, the second battery 2 continues to provide stable power to the system. At this time, the first battery 1 is reinserted (the first power management module 1 judges the charge status of the inserted first battery 1). If the inserted first battery 1 is fully charged, the first anti-backflow module 6 is turned on, and the first battery 1 supplies power to the system through the upper branch. At the same time, when the system judges that the charge of the second battery 2 is less than a certain percentage (e.g., 30%), it will simultaneously raise the voltage through the second power management module 4 to charge the second battery 2. At this time, the second anti-backflow module 7 of the lower branch is in the off state. When the charge of the second battery 2 reaches 30%, it stops charging. In practical applications, the logic here is: if the newly inserted first battery 1 has sufficient charge, the second battery 2 needs to be charged to ensure that the charge of the second battery 2 is at 30%. This is based on the principle of extending the life of the second battery 2. At this time, the second battery 2 is in a better state of preservation and can be stored for a long time. At the same time, 30% of the battery capacity is sufficient to allow time for the system to replace the first battery 1.

[0092] (3) Specifically, when the charge of the first battery 1 is much higher than that of the second battery 2 (which is 30% higher), the voltage of the first battery 1 is higher than that of the second battery 2. At this time, due to the characteristics of the hardware design, the first anti-backflow module 6 is turned on and the second anti-backflow module 7 is turned off, prioritizing the consumption of the charge of the first battery 1. If it is detected that the charge of the first battery 1 is slowly decreasing until it is the same as that of the second battery 2, the first anti-backflow module 6 and the second anti-backflow module 7 are turned on in coordination according to the charge status of the internal and external batteries, and the internal and external batteries are used simultaneously, slowly consuming the charge.

[0093] (4) In special scenarios, if both the inner and outer batteries are simultaneously depleted to less than 30% of their capacity: After the first battery 1 is removed, the newly inserted first battery 1 is not fully charged. Based on the principle of increasing the lifespan of the internal battery in (2), if the capacity of the first battery 1 is higher than 30%, the first battery 1 will still charge the second battery 2 until the second battery 2 reaches 30% to ensure its use when switching to the first battery 1. If the capacity of the first battery 1 is also less than 30% while the second battery 2 is being charged, then according to the hardware design of the portable platform 100, the battery with the higher capacity will be consumed until they are equal and consumed simultaneously.

[0094] (5) When the external power adapter 10 is plugged in, the portable platform 100 is quickly charged. At this time, the internal and external batteries are charged equally through the first power management module 3 and the second power management module 4. If the first battery 1 is unplugged at this time, the second battery 2 is charged. When the first battery 1 is plugged in, equal charging is performed according to the charge levels of the second battery 2 and the first battery 1. The strategy logic is: prioritize charging the battery with lower charge level, and after the charge levels are equal, the internal and external batteries are charged together.

[0095] (6) Because it passes through two levels of management modules, namely the first power management module 3 and the second power management module 4, the charging efficiency of the adapter 10 for the second battery 2 is relatively lower than that for the first battery 1. Therefore, the principle is to charge the second battery 2 as much as possible when the adapter 10 is fast charging. When the adapter 10 is not connected, it is only necessary to ensure that the second battery 2 has 30% of its charge level to meet the requirements for hot-swappable replacement and long-term storage.

[0096] (7) If the battery temperature is below 0℃ or above 45℃, the battery cannot be charged. The difference between charging when the power is off and charging when the power is on is that charging when the power is off does not need to consider system consumption, while charging when the power is on needs to consider power-on losses and prioritize the allocation of power at the charging input terminal to meet the system's needs.

[0097] (8) If the adapter 10 used for the internal and external batteries is not a fast charging adapter, fast charging cannot be performed. In particular, the slow charging adapter prioritizes meeting the system's needs, and charging balance is achieved through the first power management module 3 and the second power management module 4.

[0098] In summary, the mobile platform of this application embodiment has the following advantages:

[0099] 1. The removable first battery supports hot-swapping. When the first battery is removed, because the voltage on the right end of the second anti-backflow module is lower than the voltage on the left end, the second anti-backflow module will immediately activate the moment the first battery is removed. At this time, the second battery will immediately output power to the system load, and the system will not be powered down. When the first battery is inserted, it can be determined whether the second battery or the first battery provides power based on the current charge levels of the internal and external batteries and the system's charge and discharge management strategy.

[0100] 2. Due to the use of an internal and external battery solution, the second battery can continue to power the system when the first battery is replaced, achieving permanent standby. Typically, if users of the portable platform are equipped with multiple first batteries and cycle-charge them, they can achieve indefinite battery life without interruption. This can be applied to extreme scenarios of continuous outdoor operation, providing a long-lasting system solution.

[0101] 3. This embodiment enables fast charging of either the second or first battery using an adapter, based on the system's own charging strategy. For the first battery, the mobile platform itself acts as a charging manager, and this solution allows the mobile platform to fast charge its internal first battery.

[0102] 4. The solution in this embodiment has an external output voltage function. Regardless of whether the first battery is present, it can output the power required by the external device through the interface connector (e.g., USB interface).

[0103] 5. Based on the control of the above-mentioned intelligent hardware programmable module, the embodiments of this application can realize the strategy of optimal use and optimal storage of the internal first battery.

[0115] The mobile platform further includes a power-on / off control module, which detects whether its power-on button is pressed to determine whether the mobile platform is in a powered-on or powered-off state.

[0116] The first battery is removable. When the first power management module detects that it is not connected to an external charging power source, it checks whether the first battery is in place. When the first battery is detected to be in place, the first power management module controls the first battery to supply power to the system load according to the first battery in place discharge strategy, and / or the second power management module controls the second battery to supply power to the system load according to the first battery in place discharge strategy. When the first battery is detected to be out of place, the second power management module controls the second battery to supply power to the system load according to the second battery discharge strategy.

[0117] Specifically, when the presence of the first battery is detected, the charge levels of the first and second batteries are detected.
